This reverts commit ac741ab71bb39e6977694ac0cc26678d8673cda4. Okay this looks like wasn't as fully baked as I'd led myself to believe. Revert for now for further baking.

So "git status" no longer shows these files, but the ones who works with quilt patchsets, this not makes life easier as expected. Because sometimes a work flow (at least for me) requires "quilt push -f" followed by "git status" to see unresolved merge conflicts, work on these conflicts to correct them and finalize the patch with "quilt refresh". And if there are some "*.rej" files exists in tree, for whatever reason, this means something goes really wrong there and i think this situation not deserves to be ignored.

These permissions changes are "ephemeral" however. They are lost whenever a share is mounted and unmounted, or when memory pressure forces the inode out of the cache. Because of this, we'd like to introduce a behavior change to make CIFS behave more like local DOS/Windows filesystems. When unix extensions and cifsacl support aren't enabled, then don't silently ignore changes to permission bits that can't be reflected on the server. Still, there may be people relying on the current behavior for certain applications. This patch adds a new "dynperm" (and a corresponding "nodynperm") mount option that will be intended to make the client fall back to legacy behavior when setting these modes.

Therefore when all search entries are returned, the server may return "end of search" and close the search implicitly when this bit is set by the client on the request. We check for this when a readdir is explicitly closed - but when the client notices that a directory has changed after the last operation, we attempt to close the directory before reopening by reissuing a second FindFirst. But, the directory may already been implicitly closed (due to end of search) because the first readdir finished. So we only want to issue a FindClose call in this case when we don't expect it to already be closed.

Anyway, in this case the proper error path is for device_rename to return an error code, not to generate bogus backtrace and errors. Also, to avoid possible races, the create link should be done before the remove link. This makes a device rename atomic operation like other renames.

The atm_tcp.h uses types from linux/atm.h, but does not include it. It should also use the standard __u## types from linux/types.h rather than the uint##_t types since the former can be found with the kernel already. Same goes for linux/atm.h.

The use of cli()/sti() within the do/while was a way to ensure interrupts were only disabled for short periods of time while the bulk of the time interrupts were free to occur. The use of the spin lock has eliminated the need to play with interrupts in this way while still allowing for IO to be protected. The remaining 3 sti() calls seem unneeded now that at no other point in the driver is there a call to cli().

During init-time and error-recovery (after a RISC reset), the driver disables interrupts and 'polls' for completions by calling qla2x00_poll(): static inline void qla2x00_poll(scsi_qla_host_t *ha) { ha->isp_ops->intr_handler(0, ha); } which in-turn calls the ISP registered interrupt handler.

The reason for the bug is that the time_in_range() test returns 'true' as long as the current time lies between nfsi->read_cache_jiffies and nfsi->read_cache_jiffies + nfsi->attrtimeo. In other words, if jiffies equals nfsi->read_cache_jiffies, then we still cache the attribute data.

NFSv4 hooks were not originally added since it was reasonably late in the merge window and NFSv3 was the only thing that had regressed (v4 has never supported any LSM options) This patch makes NFSv4 call into the LSM to set security options rather than just blindly dropping them with no notice to the user as happens today.

This patch fixes the association problem with 11n hidden ssid ap. Patch fixes the problem of associating with hidden ssid when all three parameters ap,essid and channel are given to iwconfig. This patch removes the condition of checking three parameters and always checks for bss in bss list while associating. Signed-off-by: Abhijeet Kolekar Signed-off-by: John W.

This patch restores ieee80211_iterate_active_interfaces() to use RTNL lock, and provides the non-RTNL version under a new name: ieee80211_iterate_active_interfaces_atomic() So far only rt2x00 uses ieee80211_iterate_active_interfaces(), and those drivers require the RTNL version of ieee80211_iterate_active_interfaces(). Since they already call that function directly, this patch will automatically fix the USB rt2x00 drivers. v2: Rename ieee80211_iterate_active_interfaces_rtnl Signed-off-by: Ivo van Doorn Acked-by: Johannes Berg Signed-off-by: John W.

Moreover, more files could be opened while we allocate a copy, in which case we end up copying only part into new descriptor table. Since what we get _is_ affected by all changes in the old range, we can get rather weird effects - e.g. dup2(0, 1024); close(0); in parallel with fork() resulting in child that sees the effect of close(), but not that of dup2() done just before that close(). What we need is to recalculate the open_count after having reacquired ->file_lock and if external fdtable we'd just allocated is too small for it, free the sucker and redo allocation.

However, the firmware also reports a limit on the maximum descriptor size allowed, and because mthca takes into account the worst case send request overhead when checking whether to allow a QP to be created, the largest number of scatter/gather entries that can be used with mthca may be limited by the maximum descriptor size rather than just by the actual s/g entry limit. This means that applications cannot actually create QPs with max_send_sge equal to the limit returned by ib_query_device(). Fix this by checking if the maximum descriptor size imposes a lower limit and if so returning that lower limit.

There are a few different types of debug trap exceptions, though now that they are all going through a special jump table, the restorer needs to be unified as well. Presently this is falling through the ret_from_fork path, which more or less does the right thing on SH-3/4 whilst being completely unsuitable on MMU-less targets. Ultimately what we want here is a branch through the platform's restore_all directly, without worrying about the retval being clobbered. We can accomplish that through a branch to __restore_all directly, so switch it so we come back from the jump table and branch to the restorer. This fixes up a recursion in the nommu WARN_ON() path, as well as some other userspace nastiness where said recursion caused serious stack corruption.

There are two principal pieces of data that need to be tracked: the list of pages that comprise the completed RPC and the SGE of dma mapped pages to refer to this list of pages. Previously this whole bit was managed as a linked list of contexts with the context containing the page list buried in this list. This patch simplifies this processing by not keeping a linked list, but rather only a pionter from the last submitted RDMA_READ's context to the context that maps the set of pages that describe the RPC. This significantly simplifies this code path. SGE contexts are cleaned up inline in the DTO path instead of at read completion time.

Since the DDR controller only returns the valid portion of a read request, the bridge will prevent other PLB masters from completing their transactions. This implements the recommended workaround for this errata for chips that use older versions of firmware that do not already handle it. The last 4KiB of memory are hidden from the kernel to prevent the problem transactions from occurring.

SKB BUG: Invalid truesize (272) len=72, sizeof(sk_buff)=208 When L2TP adds its header in the transmit path, it might need to increase the headroom of the skb. In some cases, the increased headroom trips a kernel bug when the skb is freed because the skb has grown beyond its truesize value. The fix is to increase the truesize by the amount of headroom added, after orphaning the skb. While here, fix a misleading comment. Thanks to Iouri Kharon for the initial report and testing the fix.

When clearing the irq status for a specific port, the driver read the global SEQMASK register. This is wrong because that clears the irq status for _all_ ports. 2. pdc_thaw() incorrectly added the PDC_INT_SEQMASK host register offset to a per-port ata engine base address. This resulted in it reading the unrelated PDC_PKT_SUBMIT register, which did not have the desired irq status clearing effect. In both cases the fix is to read from the port's Command/Status register. This also matches what Promise's own driver does.

In sata_promise there are three distinct mmio address spaces: 1. global registers, offsets from host->iomap[PDC_MMIO_BAR] 2. per-port ATA registers, offsets from ap->ioaddr.cmd_addr 3. per-port SATA registers, offsets from ap->ioaddr.scr_addr The driver currently often fails to indicate which address space a given mmio base pointer refers to, which is a source of bugs and confusion (see recent pdc_thaw() irq clearing bug; it's also been an obstacle for the pending NCQ extensions). To reduce these problems, adopt a coding style where the name of a base pointer always indicates which address space it refers to: 1. global registers: host_mmio 2. per-port ATA registers: ata_mmio 3. per-port SATA registers: sata_mmio Also rearrange register offset definitions to clearly indicate which address space they belong to, and add a symbolic definition for the previously hard-coded PHYMODE4 register.

This had two race conditions. 1: hotplug could occur after reset but before SError is cleared and libata won't know about it. 2: hotplug could occur after all the reset is complete but before the port is thawed. As all events are cleared on thaw, the hotplug event would be lost. Commit ac371987a81c61c2efbd6931245cdcaf43baad89 kills the first race by clearing SError during link resume but before link onlineness test. However, this doesn't fix race #2 and in some cases clearing SError after SRST is a good idea. This patch solves this problem by cross checking link onlineness with classification result after SError is cleared and port is thawed. Reset is retried if link is online but all devices attached to the link are unknown. As all devices will be revalidated, this one-way check is enough to ensure that all devices are detected and revalidated reliably. This, luckily, also fixes the cases where host controller returns bogus status while harddrive is spinning up after hotplug making classification run before the device sends the first FIS and thus causes misdetection. Low level drivers can bypass the logic by setting class explicitly to ATA_DEV_NONE if ever necessary (currently none requires this).

This does not match the behaviour of the bay driver, and may result in confusion when two hotplug requests are received for the same device. This patch limits the hotplug notification to removable ACPI devices, which in turn allows it to use the _STA method to determine whether the device has been removed or inserted. On removal, devices are marked as detached. On insertion, a hotplug scan is started. This should avoid lockups caused by the ata layer attempting to scan devices which have been removed. The uevent sending is moved outside the spinlock in order to avoid a warning generated by it firing when interrupts are disabled.

Miller" Date: Mon, 19 May 2008 23:46:00 -0700 Subject: sparc64: Add global register dumping facility. When a cpu really is stuck in the kernel, it can be often impossible to figure out which cpu is stuck where. The worst case is when the stuck cpu has interrupts disabled. Therefore, implement a global cpu state capture that uses SMP message interrupts which are not disabled by the normal IRQ enable/disable APIs of the kernel. As long as we can get a sysrq 'y' to the kernel, we can get a dump. Even if the console interrupt cpu is wedged, we can trigger it from userspace using /proc/sysrq-trigger The output is made compact so that this facility is more useful on high cpu count systems, which is where this facility will likely find itself the most useful :) Signed-off-by: David S.

Since 2.6.25 the HID_QUIRK_APPLE_HAS_FN quirk is enabled even for non-laptop Apple keyboards of the Aluminium series. The USB version of these don't need Numlock emulation, like the laptop (and Aluminium Wireless) do, as they have a proper keypad. This patch splits the Numlock emulation for Apple keyboards in a different quirk flag, so that it can be enabled for all the keyboards but the Aluminium USB ones. If the Numlock emulation is enabled for Aluminium USB keyboards, the JKL and UIO keys become the numeric pad, and the rest of the keyboard is disabled, included the key used to disable Numlock. Additionally, these keyboard should not have a Numlock at all, as the Numlock key is instead replaced by the 'Clear' key as usual for Apple USB keyboards.

Previously it was defined as a "long" which means that it was too short to cover a 32-bit PAE pte entry. It is now defined as a pteval_t, which is an integer type long enough to contain a full pte (or pmd, pud, pgd). This fixes an Xorg crash on 32-bit x86 with PAE due to corruption of the NX bit in mprotect due to the incorrect type/value of PTE_MASK reported by Hugh Dickins: "Yes, thanks Jeremy: I've checked that each stage builds and runs X on my boxes here, x86_32 and x86_32+PAE and x86_64. (So even 1/8 is enough to fix the PAT pte_modify issue, though 2/8 then fixes compiler warnings.)"

The node_id and generation returned by GET_INFO will be outdated, but INITIATE_BUS_RESET would still cause a bus reset, and GET_CYCLE_TIMER will return data. And if you guess the correct generation to use, you can send requests to a different device on the bus, and get responses back.

So, create two new functions, deviec_create_vargs() and device_create_drvdata() that take this new field. device_create_drvdata() will go away in 2.6.27 as the drvdata field will just be moved to the device_create() call as it should be.

This is not a problem; the only issue is to make sure that the actual descriptors used do not overflow the maximum descriptor size, so check this instead. Clamp the returned max_send_sge value to be no bigger than what query_device returns for the max_sge to avoid confusing hapless users, even if the hardware is capable of handling a few more s/g entries. This bug caused NFS/RDMA mounts to fail when the server adapter used the mlx4 driver.

Otherwise the return values from nf_hook and dst_output may clash as they both use the value 1 but for different purposes. When that clash occurs this can cause a packet to be used after it has been freed which usually leads to a crash. Because the offending value is only returned from dst_output with qdiscs such as HTB, this bug is normally not visible. Thanks to Marco Berizzi for his perseverance in tracking this down.

If the loop is executed multiple times in the tasklet then the variables may see changes from previous packets. For TKIP, this results in 'Invalid Michael MIC' errors if two packets are processed in the tasklet: rxs.flag gets set to RX_DECRYPTED by mac80211 when it decrypts the first encrypted packet. The subsequent packet will have RX_DECRYPTED set upon entry to mac80211, so mac80211 will not try to decrypt it. We currently initialize all but two fields in the structures, so fix the other two.

The test randomly causes the HCA physical port to go down then up. The cause of this is that ipoib_mcast_join_finish() processing happen just after ipoib_mcast_dev_flush() was invoked (in which case the broadcast pointer is NULL). This patch tests for and handles the case where priv->broadcast is NULL.

The default value of retries1 is 3. So if the path mtu changes and ICMP frag needed is lost for the first 3 retransmits or if it gets delayed until 3 retransmits are done, TCP doesn't update MSS correctly and continues to retransmit the orginal message until it timesout after tcp_retries2 retransmits. I am seeing this issue even with the latest 2.6.25.4 kernel. In tcp_retransmit_timer(), when retransmits counter exceeds tcp_retries1 value, the dst cache entry of the socket is reset. At this time, if we receive an ICMP frag needed message, the dst entry gets updated with the new MTU, but the TCP sockets dst_cache entry remains NULL. So the next time when we try to retransmit after the ICMP frag needed is received, tcp_retransmit_skb() gets called. Here the cur_mss value is calculated at the start of the routine with a NULL sk_dst_cache. Instead we should call tcp_current_mss after the rebuild_header that caches the dst entry with the updated mtu. Also the rebuild_header should be called before tcp_fragment so that skb is fragmented if the mss goes down. Signed-off-by: Sridhar Samudrala Signed-off-by: David S.

This was observed with ARP frames (skb->len = 42 bytes, !skb_cloned(), skb_tailroom = 84 bytes). Then in skb_pad(), the first condition is true, where skb->len is not updated. As a consequence, the driver uses 42 bytes instead of the 60 bytes, and the ARP frame never makes it onto the wire.

To do this without disable_irq()/enable_irq() pair we should fully protect the handler. Luckily, it's already using irqsave spinlock, the only unprotected place is interrupts re-enabling write. It was safe to re-enable interrupts without holding the spinlock, but with netpoll possibility now it doesn't seem so. Patch was tested using netconsole and KGDBoE.

So far, it called nla_parse_nested() to parse the stream of nested attributes which was wrong, as nla_parse_nested() expects a container attribute as data which holds the attribute stream. It needs to call nla_parse() directly while pointing at the next possible alignment point after the struct in the beginning of the attribute.

I could also reproduce the problem on a 4 way z/VM host with a 64 way guest. It turned out that the guest was consuming all available cpus mostly for spinning on scheduler locks like rq->lock. This is expected as the threads are calling yield all the time. The problem is now, that the host scheduling decisings together with the guest scheduling decisions and spinlocks not being fair managed to create an interesting scenario similar to a live lock. (Sometimes the hang resolved itself after some minutes) Changing stop_machine to yield the cpu to the hypervisor when yielding inside the guest fixed the problem for me. While I am not completely happy with this patch, I think it causes no harm and it really improves the situation for me. I used cpu_relax for yielding to the hypervisor, does that work on all architectures? p.s.: If you want to reproduce the problem, cpu hotplug and kprobes use stop_machine_run and both triggered the problem after some retries.

This misses inode size updates when the data flushed by the fsync() is extending the file. Hence, like fdatasync(), we need to wait for I/o completion first, then check the inode for cleanliness. Doing so makes the behaviour of xfs_fsync() identical for fsync and fdatasync and we *always* use synchronous semantics if the inode is dirty. Therefore also kill the differences and remove the unused flags from the xfs_fsync function and callers.

Eventually, when the inode is revalidated, it changes to have the file_mode or dir_mode for the mount. This is confusing to users who expect that the mode shouldn't change this way. It's also problematic since only the mode is treated this way, not the uid or gid. Suppose you have a CIFS mount that's mounted with: uid=0,gid=0,file_mode=0666,dir_mode=0777 ...if an unprivileged user comes along and does this on the mount: mkdir -m 0700 foo touch foo/bar ...there is a period of time where the touch will fail, since the dir will initially be owned by root and have mode 0700. If the user waits long enough, then "foo" will be revalidated and will get the correct dir_mode permissions. This patch changes cifs_mkdir and cifs_create to not overwrite the mode found by the initial cifs_get_inode_info call after the inode is created on the server. Legacy behavior can be reenabled with the new "dynperm" mount option.

Have CIFS silently ignore ownership changes that can't be persistently stored on the server unless the "setuids" option is explicitly specified.

When performing a "recovery" or "check" pass on a RAID1 array, we read from each device and possible, if there is a difference or a read error, write back to some devices. We use the same 'bio' for both read and write, resetting various fields between the two operations. We forgot to reset bv_offset and bv_len however. These are often left unchanged, but in the case where there is an IO error one or two sectors into a page, they are changed. This results in correctable errors not being corrected properly. It does not result in any data corruption.

In some configurations, a raid6 resync can be limited by CPU speed (Calculating P and Q and moving data) rather than by device speed. In these cases there is nothing to be gained byt serialising resync of arrays that share a device, and doing the resync in parallel can provide benefit. So add a sysfs tunable to flag an array as being allowed to resync in parallel with other arrays that use (a different part of) the same device.

When we get any IO error during a recovery (rebuilding a spare), we abort the recovery and restart it. For RAID6 (and multi-drive RAID1) it may not be best to restart at the beginning: when multiple failures can be tolerated, the recovery may be able to continue and re-doing all that has already been done doesn't make sense. We already have the infrastructure to record where a recovery is up to and restart from there, but it is not being used properly. This is because: - We sometimes abort with MD_RECOVERY_ERR rather than just MD_RECOVERY_INTR, which causes the recovery not be be checkpointed. - We remove spares and then re-added them which loses important state information. The distinction between MD_RECOVERY_ERR and MD_RECOVERY_INTR really isn't needed. If there is an error, the relevant drive will be marked as Faulty, and that is enough to ensure correct handling of the error. So we first remove MD_RECOVERY_ERR, changing some of the uses of it to MD_RECOVERY_INTR. Then we cause the attempt to remove a non-faulty device from an array to fail (unless recovery is impossible as the array is too degraded). Then when remove_and_add_spares attempts to remove the devices on which recovery can continue, it will fail, they will remain in place, and recovery will continue on them as desired. Issue: If we are halfway through rebuilding a spare and another drive fails, and a new spare is immediately available, do we want to: 1/ complete the current rebuild, then go back and rebuild the new spare or 2/ restart the rebuild from the start and rebuild both devices in parallel. Both options can be argued for. The code currently takes option 2 as a/ this requires least code change b/ this results in a minimally-degraded array in minimal time.

Add GENHD_FL_SUPPRESS_PARTITION_INFO, which was present in rd.c. All kernels prior to 2.6.25 weren't displaying ramdisks in /proc/partitions. Since there are many userspace tools using information from /proc/partitions some of them may now behave incorrectly (I didn't tested any though). For example before 2.6.25 /proc/partitions was empty if no block devices like hard disks and such were detected by kernel. Now all 16 ramdisks are always visible there. Some software may rely on such information (I mean, on empty /proc/partitions). There was quite similar situation back in 2004, and ramdisks were excluded back from displaying. Thats why I called this a regression (maybe a bit unfortunate). See this patch for info: http://kernel.org/pub/linux/kernel/people/akpm/patches/2.6/2.6.3-rc2/2.6.3-rc2-mm1/broken-out/nbd-proc-partitions-fix.patch I also think that someone somewhere (long time ago) excluded ramdisks from /proc/partitions for good reasons. It is possible that now such new "feature" is harmless, but I think there are more chances that someone will say "hey, /proc/partitions has changed, now my software doesn't work" then "hey where did my new 2.6.25 feature go". nbd devices are also excluded, maybe for very same (unknown to me) reasons.

The change is that previously when cgroup_clone() was called (currently only from the unshare path in ns_proxy cgroup, you'd get a new group named "node_$pid" whereas now you'll get a group named after just your pid.) The only users who would notice it are those who are using the ns_proxy cgroup subsystem to auto-create cgroups when namespaces are unshared - something of an experimental feature, which I think really needs more complete container/namespace support in order to be useful. I suspect the only users are Cedric and Serge, or maybe a few others on containers@lists.linux-foundation.org. And in fact it would only be noticed by the users who make the assumption about how the name is generated, rather than getting it from the /proc//cgroups file for the process in question. Whether the change is actually needed or not I'm fairly agnostic on, but I guess it is more elegant to just use the pid as the new group name rather than adding a fairly arbitrary "node_" prefix on the front.

On penalty of the oopsing reported by Sebastian Siewior ... This is a partial fix, adding handshaking between the lower level (SPI messaging) and the file operations using the spi_dev. (It also fixes an issue where reads and writes didn't return the number of bytes sent or received.) There's still a refcounting issue to be addressed (separately).

The inode in this case *only* has its mode changed in memory on the client. This is problematic since it can change any time the inode is purged from the cache. This patch makes cifs_setattr silently ignore most mode changes when unix extensions and cifsacl support are not enabled, and when the share is not mounted with the "dynperm" option. The exceptions are: When a mode change would remove all write access to an inode we turn on the ATTR_READONLY bit on the server and remove all write bits from the inode's mode in memory. When a mode change would add a write bit to an inode that previously had them all turned off, it turns off the ATTR_READONLY bit on the server, and resets the mode back to what it would normally be (generally, the file_mode or dir_mode of the share).

If only one watchdog is enabled, when the core that doesn't enable the watchdog is hung, system can't reset because no watchdog is running on it. That's bad. It means we must enable watchdogs on both cores. We can use smp_call_function() to send appropriate messages to all the other cores to enable and update the watchdog.

Change sigqueue_free() to clear SIGQUEUE_PREALLOC but leave sigqueue on list if it is queued. This is a user-visible change. If the signal is blocked, it stays queued after sys_timer_delete() until unblocked with the "stale" si_code/si_value, and of course it is still counted wrt RLIMIT_SIGPENDING which also limits the number of posix timers.

This approach was suggested by Austin Clements from the very beginning, and then by Linus. As Austin pointed out, the execing task can be killed by SI_TIMER signal because exec flushes the signal handlers, but doesn't discard the pending signals generated by posix timers. Perhaps not a bug, but people find this surprising.

To avoid divide-by-zero, the implementation previously ignored RTTs smaller than 4 microseconds when performing integer division RTT/4. When the RTT reached a value less than 4 microseconds (as observed on loopback), this prevented the Window Counter CCVal value from advancing. As a result, the receiver stopped sending feedback. This in turn caused non-ending expiries of the nofeedback timer at the sender, so that the sending rate was progressively reduced until reaching the minimum of one packet per 64 seconds. The patch fixes this bug by handling integer division more intelligently. Due to consistent use of dccp_sample_rtt(), divide-by-zero-RTT is avoided.

I tracked this down to a pretty obscure little bug. The LSI fusion drivers for SAS and Fibre Channel both use their respective transport layers. Those transport layers increment the target number assigned to new targets. The routine __scsi_scan_target uses the "this_id" element of the Scsi_Host structure to avoid scanning the scsi host adapter. Both fusion drivers set "this_id" from a value returned in a firmware PortFacts response. For my particular test case (SAS) the firmware id assigned to the initiator was 173. After enough raid resets to cause the raid targets to go and come a sufficient number of times, the id assigned by the transport to a raid target would match the id assigned by the host adapter to the "this_id" field, resulting in that target not being scanned. Fix by not assigning this_id and not checking it in slave_configure.

Such faults may initiate a cascade of repeated illegal operation faults within OS interruption handlers. The specific behavior is OS dependent. Implication: An application causing an illegal operation fault with specific RSE state may result in a series of illegal operation faults and an eventual OS stack overflow condition. Workaround: OS interruption handlers that switch to kernel backing store implement a check for invalid RSE state to avoid the series of illegal operation faults. The core of the workaround is the RSE_WORKAROUND code sequence inserted into each invocation of the SAVE_MIN_WITH_COVER and SAVE_MIN_WITH_COVER_R19 macros. This sequence includes hard-coded constants that depend on the number of stacked physical registers being 96. The rest of this patch consists of code to disable this workaround should this not be the case (with the presumption that if a future Itanium processor increases the number of registers, it would also remove the need for this patch). Move the start of the RBS up to a mod32 boundary to avoid some corner cases. The dispatch_illegal_op_fault code outgrew the spot it was squatting in when built with this patch and CONFIG_VIRT_CPU_ACCOUNTING=y Move it out to the end of the ivt.

On such system, slot initialization would fail because of name collision. The shpchp driver already have a "slot_with_bus" module option which adds the bus number into the slot name.

(1) Clear all events bits in Slot Status register to prevent the pciehp driver from detecting the spurious events that would have been occur before pciehp loading.

Nordholz in http://bugzilla.kernel.org/show_bug.cgi?id=10751. The command completed bit in Slot Status register applies only to commands issued to control the attention indicator, power indicator, power controller, or electromechanical interlock. However, writes to other parts of the Slot Control register would end up writing to the control fields. Hence, any write to Slot Control register is considered as a command. However, if the controller doesn't support any of attention indicator, power indicator, power controller and electromechanical interlock, command completed bit would not set in writing to Slot Control register. In this case, we should not wait for command completed bit set, otherwise all commands would be considered not completed in timeout seconds (1 sec.). The cause of the problem is pciehp driver didn't take this situation into account. This patch changes pciehp to take it into account. This patch also add the check for "No Command Completed Support" bit in Slot Capability register. If it is set, we should not wait for command completed bit set as well. This problem seems to be revealed by the commit c27fb883dffe11aa4cb35ecea1fa1832ba45d4da that fixed the bug that pciehp did not wait for command completed properly (pciehp just ignored the command completion event).

For this, current pciehp wait for 1 second after issuing the power off command in hpc_power_off_slot() function. But waiting for 1 second in hpc_power_off_slot() can make pciehp probing slow-down because pciehp probe code calls hpc_power_off_slot() if the slot is not occupied just in case. We don't need to wait for 1 second at the pciehp probe time because there is no action on that empty slot. So move 1 second wait from hpc_power_off_slot() to the caller of hpc_power_off_slot().

TID and sta_info are extracted in ADDBA Timer expiry function through the timer handler's argument. The problem is extracging the TID (which was stored in timer_to_tid[] array of type "u8") through "int *" typecast which may also yield unwanted bytes for the MSB of TID that results in incorrect sta_info and ieee80211_local pointers. ieee80211_local pointer is NULL as illustrated below, it crashes in sta_info_get(). The problem started when extracting ieee80211_local pointer out of sta_info iteself and eventually crashed in stat_info_get(). The proper way to fix is to change the data type of TID to u8 instead of u16. However changing all the occurences requires some prototype changes as well. We should fix this in upcoming patches.

HOWEVER, this assumes that the rfcomm_sk_state_change() function always gets called with the rfcomm_dlc_lock() taken. This is the case for all but one case, and in that case where we don't have the lock, we do a double unlock followed by an attempt to take the lock, which due to underflow isn't going anywhere fast. This patch fixes this by moving the stragling case inside the lock, like the other usages of the same call are doing in this code.

Uninitialised Apple iSight drivers present with a distinctive USB ID. Once firmware has been uploaded, they disconnect and reconnect with a new ID. At this point they can be driven by the uvcvideo driver. As this is unique to the Apple cameras and not functionality shared by any other UVC devices, it makes sense to provide the firmware loading functionality in a separate driver. This driver will read an isight.fw file extracted from the Apple driver using the tools at http://bersace03.free.fr/ift/ and upload it to the camera. It will also handle the case where the device loses its firmware during hibernation and must have it reloaded.

The problem is that generic_disconnect() is called with the device lock held, and it removes a bunch of device attributes from sysfs. If a user task happens to be running an attribute method at the time, the removal will block until the method returns. But at least one of the attribute methods (the store routine for power/level) needs to acquire the device lock! This patch (as1093) eliminates the deadlock by moving the calls to create and remove the sysfs attributes from the usb_generic driver into usb_new_device() and usb_disconnect(), where they can be invoked without holding the device lock. Besides, the other sysfs attributes are created when the device is registered and removed when the device is unregistered. So it seems only fitting for the extra attributes to be created and removed at the same time.

Now it will contain the device descriptor followed by all the configuration descriptors, not just the descriptor for the current config. Userspace libraries want to have access to the kernel's cached descriptor information, so they can learn about device characteristics without having to wake up suspended devices. So far the only user of this attribute is the new libusb-1.0 library; thus changing its contents shouldn't cause any problems. This should be considered for 2.6.26, if for no other reason than to minimize the range of releases in which the attribute contains only the current config descriptor. Also, it doesn't hurt that the patch removes the device locking -- which was formerly needed in order to know for certain which config was indeed current.

The ehci->is_tdi_rh_tt flag is redundant, since it means the same thing as the hcd->has_tt flag, so it is removed and the other flag used in its place. Some of the bus-glue files didn't get the relinquish_port method added to their hc_driver structures. Although that routine currently doesn't do anything for controllers with an integrated TT, in the future it might. So the patch adds it where it is missing. Lastly, some of the bus-glue files have erroneous entries for their hc_driver's suspend and resume methods. These method pointers are specific to PCI and shouldn't be used otherwise. (The patch also includes an invisible whitespace fix.)

That the current scheduling code is wrong is clear on the face of it: Sometimes it returns -EL2NSYNC (meaning that an URB couldn't be scheduled because it was submitted too late), but it does this even when the URB_ISO_ASAP flag is set (meaning the URB should be scheduled as soon as possible). The new code properly implements as-soon-as-possible scheduling, assigning the next unexpired slot as the URB's starting point. It also is more careful about checking for Iso URB completion: It doesn't bother to check for activity during frames that are already over, and it allows for the possibility that some of the URB's packets may have raced the hardware when they were submitted and so never got used (the packet status is set to -EXDEV). This fixes problems several people have experienced with USB video applications.

The fundamental problem is that queue headers get removed from the schedule too quickly, since the code checks for a counter advancing rather than making an actual time-based check. The latency involved in removing the queue header and then relinking it can severely degrade certain kinds of workloads. The patch replaces a simple counter with a timestamp derived from the controller's uframe value. In addition, the delay for unlinking an idle queue header is increased from 5 ms to 10 ms; since some controllers (nVidia) have a latency of up to 1 ms for unlinking, this reduces the relative impact from 20% to 10%. Finally, a logical error left over from the IAA watchdog-timer conversion is corrected. Now the driver will always either unlink an idle queue header or set up a timer to unlink it later. The old code would sometimes fail to do either.

Anthony Liguori points out that three different transports use the virtio code, but each one keeps its own counter to set the virtio_device's index field. In theory (though not in current practice) this means that names could be duplicated, and that risk grows as more transports are created. So we move the selection of the unique virtio_device.index into the common code in virtio.c, which has the side-benefit of removing duplicate code. The only complexity is that lguest and S/390 use the index to uniquely identify the device in case of catastrophic failure before register_virtio_device() is called: now we use the offset within the descriptor page as a unique identifier for the printks.

Please look at virtnet_poll: [...] /* Out of packets? */ if (received < budget) { netif_rx_complete(vi->dev, napi); if (unlikely(!vi->rvq->vq_ops->enable_cb(vi->rvq)) && napi_schedule_prep(napi)) { vi->rvq->vq_ops->disable_cb(vi->rvq); __netif_rx_schedule(vi->dev, napi); goto again; } } If an interrupt arrives after netif_rx_complete, a second poll routine can run on a different cpu. The second check for napi_schedule_prep would prevent any harm in the network stack, but we have called enable_cb possibly after the disable_cb in skb_recv_done. static void skb_recv_done(struct virtqueue *rvq) { struct virtnet_info *vi = rvq->vdev->priv; /* Schedule NAPI, Suppress further interrupts if successful. */ if (netif_rx_schedule_prep(vi->dev, &vi->napi)) { rvq->vq_ops->disable_cb(rvq); __netif_rx_schedule(vi->dev, &vi->napi); } } That means that the second poll routine runs with interrupts enabled, which is ok, since we can handle additional interrupts. The problem is now that the second poll routine might also call enable_cb, triggering the BUG. The only solution I can come up with, is to remove the BUG statement in enable_cb - similar to disable_cb. Opinions or better ideas where the oops could come from?

There's a similar mechanism for the host to suppress notifications coming from the guest: in that case, we ignore the suppression if the ring is completely full. It turns out that life is simpler if the host similarly ignores callback suppression when the ring is completely empty: the network driver wants to free up old packets in a timely manner, and otherwise has to use a timer to poll. We have to remove the code which ignores interrupts when the driver has disabled them (again, it had no locking and hence was unreliable anyway).

Calling the generic vmemmap_alloc_block() function to get initialized memory is a nice idea, however that function is __meminit annotated and therefore the function might be gone if we try to call it later. This can happen if a DCSS segment gets added. So basically revert the patch and clear the memmap explicitly to fix the original bug.

I know the following patch fixes the issue, it clearly also adds port multipler support. The current 2.6.26-rc driver is broken. On boot with debug enabled we get something like (w/o this patch): spurious interrupt!!, CC = 0x1 interrupt status 0x1 xx_scr_read, reg_in = 1 spurious interrupt!!, CC = 0x1 interrupt status 0x1 xx_scr_read, reg_in = 1 spurious interrupt!!, CC = 0x1 interrupt status 0x1 xx_scr_read, reg_in = 1 .. continues for ever. This change fixes this as a side effect of adding port multiplier support.

As external modules often do: ccflags-y := -I$(src) We had problems because $(src) was unassinged and gcc then used the next parameter for -I resulting in strange build failures. Fix is to assign $(src) and $(obj) when building external modules.

Morgan" Date: Tue, 27 May 2008 22:05:17 -0700 Subject: capabilities: remain source compatible with 32-bit raw legacy capability support. Source code out there hard-codes a notion of what the _LINUX_CAPABILITY_VERSION #define means in terms of the semantics of the raw capability system calls capget() and capset(). Its unfortunate, but true. Since the confusing header file has been in a released kernel, there is software that is erroneously using 64-bit capabilities with the semantics of 32-bit compatibilities. These recently compiled programs may suffer corruption of their memory when sys_getcap() overwrites more memory than they are coded to expect, and the raising of added capabilities when using sys_capset(). As such, this patch does a number of things to clean up the situation for all. It 1. forces the _LINUX_CAPABILITY_VERSION define to always retain its legacy value. 2. adopts a new #define strategy for the kernel's internal implementation of the preferred magic. 3. deprecates v2 capability magic in favor of a new (v3) magic number. The functionality of v3 is entirely equivalent to v2, the only difference being that the v2 magic causes the kernel to log a "deprecated" warning so the admin can find applications that may be using v2 inappropriately. [User space code continues to be encouraged to use the libcap API which protects the application from details like this. libcap-2.10 is the first to support v3 capabilities.] Fixes issue reported in https://bugzilla.redhat.com/show_bug.cgi?id=447518.

The FRV, SH and Xtensa ports are also missing a memory clobber, so I thought it would be polite to let you know. The bug manifests as dropped network packets (obviously they have the wrong checksum). It started appearing for parisc with GCC 4.3. The GCC manual says: If your assembler instructions access memory in an unpredictable fashion, add `memory' to the list of clobbered registers. This will cause GCC to not keep memory values cached in registers across the assembler instruction and not optimize stores or loads to that memory. I see that FRV has a 400 byte memory output which may prevent this problem from appearing, but SH and Xtensa have nothing to prevent this bug. Hope this saves you a few days of debugging.

RSK7203 is supportable through the generic machvec, so we add a defconfig for those bits. This gets updated with more complete board support later.

Some hardware uses this to configure hardware specific features such as IrDA mode on serial ports. Unfortunately the serial layer does not provide this feature or pass it down to drivers. Blackfin used to hack around this by rewriting the tty ops, but those are now properly shared and const so the hack fails. Instead provide the proper operations. This change plus a follow up from the Blackfin guys is needed to avoid blackfin losing features in this release.

Here fixed it by unlock dlc before rfcomm_dev_get in rfcomm_dev_state_change. why not unlock just before rfcomm_dev_put? it's because there's another problem. rfcomm_dev_get/rfcomm_dev_del will take rfcomm_dev_lock, but in rfcomm_dev_add the lock order is : rfcomm_dev_lock --> dlc lock so I unlock dlc before the taken of rfcomm_dev_lock. Actually it's a regression caused by commit 1905f6c736cb618e07eca0c96e60e3c024023428 ("bluetooth : __rfcomm_dlc_close lock fix"), the dlc state_change could be two callbacks : rfcomm_sk_state_change and rfcomm_dev_state_change. I missed the rfcomm_sk_state_change that time. Thanks Arjan van de Ven for the effort in commit 4c8411f8c115def968820a4df6658ccfd55d7f1a ("bluetooth: fix locking bug in the rfcomm socket cleanup handling") but he missed the rfcomm_dev_state_change lock issue.

From: Jarek Poplawski There is only one function in AX25 calling skb_append(), and it really looks suspicious: appends skb after previously enqueued one, but in the meantime this previous skb could be removed from the queue. This patch Fixes it the simple way, so this is not fully compatible with the current method, but testing hasn't shown any problems. Signed-off-by: Ralf Baechle Signed-off-by: David S.

Kernel to user space ABI's need to use USER_HZ (or milliseconds), otherwise the application has to try and discover the real system HZ value which is problematic. Linux has standardized on keeping USER_HZ consistent (100hz) even when kernel is running internally at some other value. This change is small, but it breaks the ABI for older version of iproute2 utilities. But these utilities are already broken since they are looking at the psched_hz values which are completely different. So let's just go ahead and fix both kernel and user space. Older utilities will just print wrong values. Signed-off-by: Stephen Hemminger Signed-off-by: David S.

I actually suspect the logic was wrong before the changes but -rc isn't the time to play with that ata_sff_sync - ensure writes hit the device Really we want an io* operation for 'is posted' eg ioisposted(ioaddr) so that we can fix the nasty delay this causes on most systems. - ata_sff_pause - 400nS delay Ensure the command hit the device and delay 400nS - ata_sff_dma_pause Ensure the I/O hit the device and enforce an HDMA1:0 transition delay.

(UDMA the checksum will save your backside in theory) The only other complication then is devices with their own handlers. rb532 can use dma_pause but scc needs to access its own altstatus register for internal errata workarounds so directly call the drivers own altstatus function.

This latency shows up out of the blue and has been seen to be as big as 5ms! Using ftrace I found the cause of the latency. pcscd-2995 3dNh1 52360300us : irq_exit (smp_apic_timer_interrupt) pcscd-2995 3dN.2 52360301us : idle_cpu (irq_exit) pcscd-2995 3dN.2 52360301us : rcu_irq_exit (irq_exit) pcscd-2995 3dN.1 52360771us : smp_apic_timer_interrupt (apic_timer_interrupt ) pcscd-2995 3dN.1 52360771us : exit_idle (smp_apic_timer_interrupt) Here's an example of a 400 us latency. pcscd took a timer interrupt and returned with "need resched" enabled, but did not reschedule until after the next interrupt came in at 52360771us 400us later! At first I thought we somehow missed a preemption check in entry.S. But I also noticed that this always seemed to happen during a __delay call. pcscd-2995 3dN.2 52360836us : rcu_irq_exit (irq_exit) pcscd-2995 3.N.. 52361265us : preempt_schedule (__delay) Looking at the x86 delay, I found my problem. In git commit 35d5d08a085c56f153458c3f5d8ce24123617faf, Andrew Morton placed preempt_disable around the entire delay due to TSC's not working nicely on SMP. Unfortunately for those that care about latencies this is devastating! Especially when we have callers to mdelay(8). Here I enable preemption during the loop and account for anytime the task migrates to a new CPU. The delay asked for may be extended a bit by the migration, but delay only guarantees that it will delay for that minimum time. Delaying longer should not be an issue.

Specifically, pat_x_mtrr_type() is restructured to highlight, under what conditions we look for mtrr hint. pat_x_mtrr_type() uses a default type when there are any errors in mtrr lookup (still maintaining the pat consistency). And, reserve_memtype() highlights its usage ot mtrr_lookup for request type of '-1' and also defaults in a sane way on any mtrr lookup failure. pat.c looks at mtrr type of a range to get a hint on what mapping type to request when user/API: (1) hasn't specified any type (/dev/mem mapping) and we do not want to take performance hit by always mapping UC_MINUS. This will be the case for /dev/mem mappings used to map BIOS area or ACPI region which are WB'able. In this case, as long as MTRR is not WB, PAT will request UC_MINUS for such mappings. (2) user/API requests WB mapping while in reality MTRR may have UC or WC. In this case, PAT can map as WB (without checking MTRR) and still effective type will be UC or WC. But, a subsequent request to map same region as UC or WC may fail, as the region will get trackked as WB in PAT list. Looking at MTRR hint helps us to track based on effective type rather than what user requested. Again, here mtrr_lookup is only used as hint and we fallback to WB mapping (as requested by user) as default. In both cases, after using the mtrr hint, we still go through the memtype list to make sure there are no inconsistencies among multiple users.

Add tsk_used_math() checks to prevent calling math_state_restore() which can sleep in the case of !tsk_used_math(). This prevents making a blocking call in __switch_to(). Apparently "fpu_counter > 5" check is not enough, as in some signal handling and fork/exec scenarios, fpu_counter > 5 and !tsk_used_math() is possible. It's a side effect though. This is the failing scenario: process 'A' in save_i387_ia32() just after clear_used_math() Got an interrupt and pre-empted out. At the next context switch to process 'A' again, kernel tries to restore the math state proactively and sees a fpu_counter > 0 and !tsk_used_math() This results in init_fpu() during the __switch_to()'s math_state_restore() And resulting in fpu corruption which will be saved/restored (save_i387_fxsave and restore_i387_fxsave) during the remaining part of the signal handling after the context switch.

However, the actual tty-layer function that does this callback for serial devices was declared with the wrong type, having a spurious and unused 'ldisc' argument. This fixed the resulting compiler warning by just removing it.

If next valid ACK doesn't contain new SACK information TCP fails to enter into tcp_fastretrans_alert(). Thus at least high_seq is set incorrectly to a too high seqno because some new data segments could be sent in between (and also, limited transmit is not being correctly invoked there). Reordering in both directions can easily cause this situation to occur. I guess we would want to use tcp_moderate_cwnd(tp) there as well as it may be possible to use this to trigger oversized burst to network by sending an old ACK with huge amount of SACK info, but I'm a bit unsure about its effects (mainly to FlightSize), so to be on the safe side I just currently fixed it minimally to keep TCP's state consistent (obviously, such nasty ACKs have been possible this far). Though it seems that FlightSize is already underestimated by some amount, so probably on the long term we might want to trigger recovery there too, if appropriate, to make FlightSize calculation to resemble reality at the time when the losses where discovered (but such change scares me too much now and requires some more thinking anyway how to do that as it likely involves some code shuffling). This bug was found by Brian Vowell while running my TCP debug patch to find cause of another TCP issue (fackets_out miscount). Signed-off-by: Ilpo Järvinen Signed-off-by: David S.

In order for this to cause corruption: 1) DSACK in the middle of previous SACK block must be generated. 2) In order to take that particular branch, part or all of the DSACKed segment must already be SACKed so that we have that in cache in the first place. 3) The new info must be top enough so that fackets_out will be updated on this iteration. ...then fack_count is updated while skb wasn't, then we walk again that particular segment thus updating fack_count twice for a single skb and finally that value is assigned to fackets_out by tcp_sacktag_one. It is safe to call tcp_sacktag_one just once for a segment (at DSACK), no need to call again for plain SACK. Potential problem of the miscount are limited to premature entry to recovery and to inflated reordering metric (which could even cancel each other out in the most the luckiest scenarios :-)). Both are quite insignificant in worst case too and there exists also code to reset them (fackets_out once sacked_out becomes zero and reordering metric on RTO). This has been reported by a number of people, because it occurred quite rarely, it has been very evasive. Andy Furniss was able to get it to occur couple of times so that a bit more info was collected about the problem using a debug patch, though it still required lot of checking around. Thanks also to others who have tried to help here. This is listed as Bugzilla #10346. The bug was introduced by me in commit 68f8353b48 ([TCP]: Rewrite SACK block processing & sack_recv_cache use), I probably thought back then that there's need to scan that entry twice or didn't dare to make it go through it just once there. Going through twice would have required restoring fack_count after the walk but as noted above, I chose to drop the additional walk step altogether here.

This, however, opens a window of opportunity for tcp_collapse() to aggregate skbs and thus potentially free the current skb used in skb_splice_bits and tcp_read_sock. This patch fixes the problem by (re-)getting the same "logical skb" after the lock has been temporary dropped. Based on idea and initial patch from Evgeniy Polyakov.

The pppol2tp driver uses private data that is referenced via the sk->sk_user_data of its UDP and PPPoL2TP sockets. This patch makes sure that the driver uses sock_hold() when it holds a reference to the sk pointer. This affects its sendmsg(), recvmsg(), getname(), [gs]etsockopt() and ioctl() handlers. Tested by ISP where problem was seen. System has been up 10 days with no oops since running this patch. Without the patch, an oops would occur every 1-2 days.

This problem can probably be worked around in other ways as well, i went for the minimal fix. Obviously, the kconfig tool should be fixed, it is not reasonable to expect driver authors to do manual dependency resolution (that kconfig itself already does) and uglify the Kconfig files. The kconfig tool did nothing to warn about this situation and did not prevent this faulty .config from being constructed.

That doesn't really work for distro kernels, so this patch allows one to choose CONFIG_OLPC and CONFIG_PCI_GOANY in order to build in OLPC support in a generic kernel (as requested by Robert Millan). This also moves GOOLPC before GOANY in the menuconfig list. Finally, make pci_access_init return early if we detect OLPC hardware. There's no need to continue probing stuff, and pci_pcbios_init specifically trashes our settings (we didn't run into that before because PCI_GOANY wasn't supported).

The CONFIG_DEBUG_SHIRQ flag is by default 'y' with all Fedora kernels since 2.6.23.

KVM allows the guest to choose one or the other (the default is Intel), and if the guest chooses incorrectly, KVM will patch it at runtime to select the correct instruction. This allows live migration between Intel and AMD machines. This patching occurs in the x86 emulator. The current code also executes the hypercall. Unfortunately, the tail end of the x86 emulator code also executes, overwriting the return value of the hypercall with the original contents of rax (which happens to be the hypercall number). Fix not by executing the hypercall in the emulator context; instead let the guest reissue the patched instruction and execute the hypercall via the normal path.

We take the task_lock and the mmap_sem. As exit_mm uses the same locks vice versa, this triggers a lockdep warning. The second problem is that dup_mm and mmput might sleep, so we must not hold the task_lock at that moment. The solution is to dup the mm unconditional and use the task_lock before and afterwards to check if we can use the new mm. dup_mm and mmput are called outside the task_lock, but we run update_mm while holding the task_lock, protection us against ptrace.

When this happens the prexor completes and the stripe is unconditionally marked "insync", effectively canceling the sync_request for the stripe. Prior to 2.6.23 this was not a problem because the prexor operation was done under sh->lock. The effect in older kernels being that the prexor would still erroneously mark the stripe "insync", but sync_request would be held off and re-mark the stripe as "!in_sync". Change the write completion logic to not mark the stripe "in_sync" if a prexor was performed. The effect of the change is to sometimes not set STRIPE_INSYNC. The worst this can do is cause the resync to stall waiting for STRIPE_INSYNC to be set. If this were happening, then STRIPE_SYNCING would be set and handle_issuing_new_read_requests would cause all available blocks to eventually be read, at which point prexor would never be used on that stripe any more and STRIPE_INSYNC would eventually be set. echo repair > /sys/block/mdN/md/sync_action will correct arrays that may have lost this race.

Pointless because ecryptfs_get_locked_page() has already brought the page up to date, and buggy because prior mmap writes will just be blown away by the decrypt call. This patch also removes the declaration of a now-nonexistent function ecryptfs_write_zeros(). Thanks to Eric Sandeen and David Kleikamp for helping to track this down. Eric said: fsx w/ mmap dies quickly ( < 100 ops) without this, and survives nicely (to millions of ops+) with it in place.

Presently we are not able to accurately size arbitrary pointers that don't come from kmalloc(), so the best we can do is sort out the compound order from the head page if it's a compound page, or default to 0-order if it's impossible to ksize() the object. Obviously this leaves quite a bit to be desired in terms of object sizing accuracy, but the behaviour is unchanged over the existing implementation, while fixing the page->index oopses originally reported here: http://marc.info/?l=linux-mm&m=121127773325245&w=2 Accuracy could also be improved by having SLUB and SLOB both set PG_slab on ksizeable pages, rather than just handling the __GFP_COMP cases irregardless of the PG_slab setting, as made possibly with Pekka's patches: http://marc.info/?l=linux-kernel&m=121139439900534&w=2 http://marc.info/?l=linux-kernel&m=121139440000537&w=2 http://marc.info/?l=linux-kernel&m=121139440000540&w=2 This is primarily a bugfix for nommu systems for 2.6.26, with the aim being to gradually kill off kobjsize() and its particular brand of object abuse entirely.

After this you'll see the c foo:bar r c foo:bar w lines in a devices.list file. Another example - consider you added 10 'c foo:bar r' permissions to some cgroup (e.g. by mistake). After this you'll see 10 c foo:bar r lines in a list file. This is weird. This situation also has one more annoying consequence. Having many items in a white list makes permissions checking slower, sine it has to walk a longer list. The proposal is to merge permissions for items, that correspond to the same device.

Previously, since pm->out was a char *, put_user was only copying 1 byte of every PFN, resulting in the top 7 bytes of each PFN not being copied. By requiring that reads be a multiple of 8 bytes, I can make pm->out and pm->end u64*s instead of char*s, which makes put_user work properly, and also simplifies the logic in add_to_pagemap a bit.

The scripts/kernel-doc perl script, some +SGML templates in Documentation/DocBook, and other tools understand +these conventions, and are used to extract this embedded documentation +into various documents. + +In order to provide good documentation of kernel functions and data +structures, please use the following conventions to format your +kernel-doc comments in Linux kernel source. + +We definitely need kernel-doc formatted documentation for functions +that are exported to loadable modules using EXPORT_SYMBOL. + +We also look to provide kernel-doc formatted documentation for +functions externally visible to other kernel files (not marked +"static"). + +We also recommend providing kernel-doc formatted documentation +for private (file "static") routines, for consistency of kernel +source code layout. But this is lower priority and at the +discretion of the MAINTAINER of that kernel source file. + +Data structures visible in kernel include files should also be +documented using kernel-doc formatted comments. + +The opening comment mark "/**" is reserved for kernel-doc comments. +Only comments so marked will be considered by the kernel-doc scripts, +and any comment so marked must be in kernel-doc format. Do not use +"/**" to be begin a comment block unless the comment block contains +kernel-doc formatted comments. The closing comment marker for +kernel-doc comments can be either "*/" or "**/". + +Kernel-doc comments should be placed just before the function +or data structure being described. + +Example kernel-doc function comment: + +/** + * foobar() - short function description of foobar + * @arg1: Describe the first argument to foobar. + * @arg2: Describe the second argument to foobar. + * One can provide multiple line descriptions + * for arguments. + * + * A longer description, with more discussion of the function foobar() + * that might be useful to those using or modifying it.

Its relatively easy to trigger by sharing (virtio-blk + usbtablet was the testcase, initially reported by Gerd von Egidy). The "remote_irr" variable is used to indicate accepted but not yet acked interrupts. Its cleared from the EOI handler. Problem is that the EOI handler clears remote_irr unconditionally, even if it reinjected another pending interrupt. In that case, kvm_ioapic_set_irq() proceeds to ioapic_service() which sets remote_irr even if it failed to inject (since the IRR was high due to EOI reinjection). Since the TMR bit has been cleared by the first EOI, the second one fails to clear remote_irr. End result is interrupt line dead. Fix it by setting remote_irr only if a new pending interrupt has been generated (and the TMR bit for vector in question set).

This leads to an infinite loop in ib_umem_get(), since the code boils down to: while (npages) { ret = get_user_pages(...); npages -= ret; } Fix this by taking the minimum as unsigned longs, so that the value of npages is never truncated. The impact of this bug isn't too severe, since the value of npages is checked against RLIMIT_MEMLOCK, so a process would need to have an astronomical limit or have CAP_IPC_LOCK to be able to trigger this, and such a process could already cause lots of mischief. But it does let buggy userspace code cause a kernel lock-up; for example I hit this with code that passes a negative value into a memory registartion function where it is promoted to a huge u64 value.

However, the support was incomplete: the completion structure was not extended with a field for the key contained in incoming send with invalidate requests. Full support for memory management extensions (send with invalidate, local invalidate, fast register through a send queue, etc) is planned for 2.6.27. Since send with invalidate is not very useful by itself, just remove the IB_DEVICE_SEND_W_INV bit before the 2.6.26 final release; we will add an IB_DEVICE_MEM_MGT_EXTENSIONS bit in 2.6.27, which makes things simpler for applications, since they will not have quite as confusing an array of fine-grained bits to check.

However, that direct scan is usually the scan that's really needed by userspace, and gets stomped on by all the broadcast scans the ipw2200 driver issues internally. Make sure the direct scan happens eventually, and as a bonus ensure that the passive scan worker is cleaned up when appropriate. The change of request_passive_scan form a struct work to struct delayed_work is only to make the set_wx_scan() code a bit simpler, it's still only used with a delay of 0 to match previous behavior.

The problem is that the added flow control check will always fail if flow control is set to autoneg and either RX or TX (or both) flow control is enabled. The driver defaults to setting flow control to autoneg and advertises both RX and TX flow control. The fix is to remove the errant check.

The first problem is that GPIO 0 and GPIO 2 have been swapped. This change prevented the administrator from turning on WOL when it is disabled in NVRAM. The fix is to add a new path for the 5761 that swaps the two GPIOs in the code as well. The second problem is that GPIO 1 could not be toggled by the driver because the GPIO is shared with the debug UART GPIO. This will prevent the administrator from being able to turn WOL off if it was enabled in NVRAM. The fix is to always disable the debug UART after a GRC reset.

However, the code like current->state = TASK_KILLABLE; schedule(); is not right, schedule() doesn't take TASK_WAKEKILL into account. This means that mutex_lock_killable(), wait_for_completion_killable(), down_killable(), schedule_timeout_killable() can miss SIGKILL (and btw the second SIGKILL has no effect). Introduce the new helper, signal_pending_state(), and change schedule() to use it. Hopefully it will have more users, that is why the task's state is passed separately. Note this "__TASK_STOPPED | __TASK_TRACED" check in signal_pending_state(). This is needed to preserve the current behaviour (ptrace_notify). I hope this check will be removed soon, but this (afaics good) change needs the separate discussion. The fast path is "(state & (INTERRUPTIBLE | WAKEKILL)) + signal_pending(p)", basically the same that schedule() does now. However, this patch of course bloats schedule().

If skb->len is bigger than the caller's buffer length, memcpy_toiovec() will go into unintialized data on the kernel heap, interpret it as an iovec and start modifying memory. The fix is to change the memcpy_toiovec() call to skb_copy_datagram_iovec() so that paged packets (rare for PPPOL2TP) are handled properly. Also check that the caller's buffer is big enough for the data and set the MSG_TRUNC flag if it is not so. Reported-by: Ilja Signed-off-by: James Chapman Signed-off-by: David S.

However, a side-effect of this scheme is that there are always xmit skbs left dangling when no new packets are sent, against the Documentation/networking/driver.txt guideline: "... it is not allowed for your TX mitigation scheme to let TX packets "hang out" in the TX ring unreclaimed forever if no new TX packets are sent." Add a timer to ensure that any time we queue new TX skbs, we will shortly free them again. This fixes an easily reproduced hang at shutdown where iptables attempts to unload nf_conntrack and nf_conntrack waits for an skb it is tracking to be freed, but virtio_net never frees it.

Such RTTs can be found e.g. when running CCID-3 over loopback. The fix removed a check against RTT < 4, but introduced a divide-by-zero bug. All steady-state RTTs in DCCP are filtered using dccp_sample_rtt(), which ensures non-zero samples. However, a zero RTT is possible on initialisation, when there is no RTT sample from the Request/Response exchange. The fix is to use the fallback-RTT from RFC 4340, 3.4. This is also better than just fixing update_win_count() since it allows other parts of the code to always assume that the RTT is non-zero during the time that the CCID is used.

The issue is that Ack Vectors must not be parsed on request sockets, since the Ack Vector feature depends on the selection of the (TX) CCID. During the initial handshake the CCIDs are undefined, and so RFC 4340, 10.3 applies: "Using CCID-specific options and feature options during a negotiation for the corresponding CCID feature is NOT RECOMMENDED [...]" And it is not even possible: when the server receives the Request from the client, the CCID and Ack vector features are undefined; when the Ack finalising the 3-way hanshake arrives, the request socket has not been cloned yet into a full socket. (This order is necessary, since otherwise the newly created socket would have to be destroyed whenever an option error occurred - a malicious hacker could simply send garbage options and exploit this.)

Since this value is scaled by 10^6, the outcome of this bug is that a loss of 8172/10^6 = 0.8172% was reported whenever the input was below the table resolution of 0.01%. This means that the value was over 80 times too high, resulting in large spikes of the initial loss interval, thus unnecessarily reducing the throughput.

Due to this bug, there will be oops on AC<->DC on some systems, where they support C-states in one DC and not in AC. The current code does ON BOOT: Look at CST and other C-state info to see whether more than C1 is supported. If it is, then acpi processor_idle does a cpuidle_register_driver() call, which internally enables the device. ON CST change notification (AC<->DC) and on suspend-resume: acpi driver temporarily disables device, updates the device with any new C-states, and reenables the device. The problem is is on boot, there are no C2, C3 states supported and we skip the register. Later on AC<->DC, we may get a CST notification and we try to reevaluate CST and enabled the device, without actually registering it. This causes breakage as we try to create /sys fs sub directory, without the parent directory which is created at register time.

If one is lucky, that illegal write would cause an OOPS, but chances are it would silently corrupt a byte. The problem was introduced in commit af116101, "ACPI: thinkpad-acpi: add sysfs led class support to thinkpad leds (v3.2)". Fix the bug by refactoring the entire code to be far more obvious on what it wants to do. Also do some defensive "constification". Issue reported by Karol Lewandowski (he's an lucky guy and got an OOPS instead of silent corruption :-) ). Root cause of the OOPS identified by Adrian Bunk . Thanks, Adrian!

Some resources have optional fields, so the size of encoded descriptors varies depending on the specific values. For example, IRQ descriptors can be either two or three bytes long. The third byte contains triggering information and can be omitted if the IRQ is edge-triggered and active high. The BIOS often assumes that IRQ descriptors in the _SRS buffer use the same format as those in the _CRS buffer, so this patch enforces that constraint. The "Start Dependent Function" descriptor also has an optional byte, but we don't currently encode those descriptors, so I didn't do anything for those. I have tested this patch on a Toshiba Portege 4000. Without the patch, parport_pc claims the parallel port only if I use "pnpacpi=off". This patch makes it work with PNPACPI.

Unfortunately modern gcc's have the tendency to strength "reduce" this into a full mod operation, which isn't necessarily any faster, and even if it were, doesn't exist if gcc implements it in libgcc. The workaround is to put a dummy asm statement in the loop to prevent gcc from performing the transformation. This patch creates a single implementation of this loop, and uses it to replace the open-coded versions I know about.

Miller" Date: Thu, 12 Jun 2008 02:22:02 -0700 Subject: net: Eliminate flush_scheduled_work() calls while RTNL is held. If the RTNL is held when we invoke flush_scheduled_work() we could deadlock. One such case is linkwatch, it is a work struct which tries to grab the RTNL semaphore. The most common case are net driver ->stop() methods. The simplest conversion is to instead use cancel_{delayed_}work_sync() explicitly on the various work struct the driver uses. This is an OK transformation because these work structs are doing things like resetting the chip, restarting link negotiation, and so forth. And if we're bringing down the device, we're about to turn the chip off and reset it anways. So if we cancel a pending work event, that's fine here. Some drivers were working around this deadlock by using a msleep() polling loop of some sort, and those cases are converted to instead use cancel_{delayed_}work_sync() as well.

Also, I found another bug about "the shares value is too large": pid1 and pid2 are set affinity to cpu#0 pid1 is attached to cg1 and pid2 is attached to cg2 if cg1/cpu.shares = 1024 cg2/cpu.shares = 2000000000 then pid2 got 100% usage of cpu, and pid1 0% if cg1/cpu.shares = 1024 cg2/cpu.shares = 20000000000 then pid2 got 0% usage of cpu, and pid1 100% And a weight of a cfs_rq is the sum of weights of which entities are queued on this cfs_rq, so the shares value should be limited to a smaller value.

Although, overflow occurs very rarely, but it break fairness when it occurs. 64-bits systems have more memory than 32-bit systems and 64-bit systems can create more process usually, so overflow may occur more frequently. This patch guarantees fairness when overflow happens on 64-bit systems. Thanks to the optimization of compiler, it changes nothing on 32-bit.

The routines are intended for handling out-of-line function call register save/restore so having them as EXPORT_SYMBOL() is counter productive (we do also need to link the same "library" code into the kernel). Without this patch a powerpc build would error out and fail to build modules with the added register save/restore module. There were two obvious solutions: 1) To link the .o file before the modpost stage 2) To ignore the symbols in modpost Option 1) was ruled out because we do not have any separate linking stage for single file modules. This patch implements option 2 - and do so only for powerpc.

This implements a few changes on top of the recent kobjsize() refactoring introduced by commit 6cfd53fc03670c7a544a56d441eb1a6cc800d72b. As Christoph points out: virt_to_head_page cannot return NULL. virt_to_page also does not return NULL. pfn_valid() needs to be used to figure out if a page is valid. Otherwise the page struct reference that was returned may have PageReserved() set to indicate that it is not a valid page. As discussed further in the thread, virt_addr_valid() is the preferable way to validate the object pointer in this case. In addition to fixing up the reserved page case, it also has the benefit of encapsulating the hack introduced by commit 4016a1390d07f15b267eecb20e76a48fd5c524ef on the impacted platforms, allowing us to get rid of the extra checking in kobjsize() for the platforms that don't perform this type of bizarre memory_end abuse (every nommu platform that isn't blackfin). If blackfin decides to get in line with every other platform and use PageReserved for the DMA pages in question, kobjsize() will also continue to work fine. It also turns out that compound_order() will give us back 0-order for non-head pages, so we can get rid of the PageCompound check and just use compound_order() directly. Clean that up while we're at it.

I see, that the 64bit has fixed the problem. I copied the same lines into 32bit part. Recorded debugs are from coLinux kernel 2.6.22.18 (virtualisation): http://www.henrynestler.com/colinux/testing/pfn-check-0.7.3/20080410-antinx/bug16-recursive-page-fault-endless.txt The physicaly memory was trimmed down to 192MB to better catch the bug. More memory gets the bug more rarely. Details, how every x86 32bit system can fail: Start from "mount_block_root", http://lxr.linux.no/linux/init/do_mounts.c#L297 There the variable "fs_names" got one memory page with 4096 bytes. Variable "p" walks through the existing file system types. The first string is no problem. But, with the second loop in mount_block_root the offset of "p" is not at beginning of page, the offset is for example +9, if "reiserfs" is the first in list. Than calls do_mount_root, and lands in sys_mount. Remember: Variable "type_page" contains now "fs_type+9" and not contains a full page. The sys_mount copies 4096 bytes with function "exact_copy_from_user()": http://lxr.linux.no/linux/fs/namespace.c#L1540 Mostly exist pages after the buffer "fs_names+4096+9" and the page fault handler was not called. No problem. In the case, if the page after "fs_names+4096" is not mapped, the page fault handler was called from http://lxr.linux.no/linux/fs/namespace.c#L1320 The do_page_fault gots an address 0xc03b4000. It's kernel address, address >= TASK_SIZE, but not from vmalloc! It's from "__getname()" alias "kmem_cache_alloc". The "error_code" is 0. "vmalloc_fault" will be call: http://lxr.linux.no/linux/arch/i386/mm/fault.c#L332 "vmalloc_fault" tryed to find the physical page for a non existing virtual memory area. The macro "pte_present" in vmalloc_fault() got a next page fault for 0xc0000ed0 at: http://lxr.linux.no/linux/arch/i386/mm/fault.c#L282 No PTE exist for such virtual address. The page fault handler was trying to sync the physical page for the PTE lockup. This called vmalloc_fault() again for address 0xc000000, and that also was not existing. The endless began... In normal case the cpu would still loop with disabled interrrupts. Under coLinux this was catched by a stack overflow inside printk debugs.

It would be interesting to see where the int3 comes from. Too bad, lockdep doesn't provide the register dump. The stacktrace also doesn't go further than the int3(), I wonder if this int3 came from userspace? The ltrace readme says "software breakpoints, like gdb", so I guess this is the case.

The ipv4 part was fine, but the ipv6 part was not done correctly. Unlike the ipv4 side, the ipv6 code already has a .destroy method for rawv6_prot. So now there were two assignments to this member, and what the compiler does is use the last one, effectively making the ipv6 parts of that changeset a NOP. Fix this by removing the: .destroy = inet6_destroy_sock, line, and adding an inet6_destroy_sock() call to the end of raw6_destroy(). Noticed by Al Viro. Signed-off-by: David S.

MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit This reverts two changesets, ec3c0982a2dd1e671bad8e9d26c28dcba0039d87 ("[TCP]: TCP_DEFER_ACCEPT updates - process as established") and the follow-on bug fix 9ae27e0adbf471c7a6b80102e38e1d5a346b3b38 ("tcp: Fix slab corruption with ipv6 and tcp6fuzz"). This change causes several problems, first reported by Ingo Molnar as a distcc-over-loopback regression where connections were getting stuck. Ilpo Järvinen first spotted the locking problems. The new function added by this code, tcp_defer_accept_check(), only has the child socket locked, yet it is modifying state of the parent listening socket. Fixing that is non-trivial at best, because we can't simply just grab the parent listening socket lock at this point, because it would create an ABBA deadlock. The normal ordering is parent listening socket --> child socket, but this code path would require the reverse lock ordering. Next is a problem noticed by Vitaliy Gusev, he noted: ---------------------------------------- >--- a/net/ipv4/tcp_timer.c >+++ b/net/ipv4/tcp_timer.c >@@ -481,6 +481,11 @@ static void tcp_keepalive_timer (unsigned long data) > goto death; > } > >+ if (tp->defer_tcp_accept.request && sk->sk_state == TCP_ESTABLISHED) { >+ tcp_send_active_reset(sk, GFP_ATOMIC); >+ goto death; Here socket sk is not attached to listening socket's request queue. tcp_done() will not call inet_csk_destroy_sock() (and tcp_v4_destroy_sock() which should release this sk) as socket is not DEAD. Therefore socket sk will be lost for freeing. ---------------------------------------- Finally, Alexey Kuznetsov argues that there might not even be any real value or advantage to these new semantics even if we fix all of the bugs: ---------------------------------------- Hiding from accept() sockets with only out-of-order data only is the only thing which is impossible with old approach. Is this really so valuable? My opinion: no, this is nothing but a new loophole to consume memory without control. ---------------------------------------- So revert this thing for now.

A feature of such code (for example, dhclient) is that it tries to operate with minimum privilege (dropping unneeded capabilities). While the dummy module doesn't restrict code execution based on capability state, the user code expects the kernel to appear to support it.

This hid two format errors - shp->shm_segsz and shp->shm_nattach are both unsigned long, but were being printed as unsigned int and signed int respectively. This leads to 32-bit truncation of SHM segment sizes reported in /proc/sysvipc/shm. (And for nattach, but that's less of a problem for most users). This patch makes the format string directly visible to gcc's format specifier checker, and fixes the two broken format specifiers.

The child becomes the new root node. To perform this operation in a manner compatible with concurrent lockless lookups, we atomically switch the root pointer from the parent to its child. However a concurrent lockless lookup may now have loaded a pointer to the parent (and is presently deciding what to do next). For this reason, we also have to keep the parent node in a valid state after shrinking the tree, until the next RCU grace period -- otherwise this lookup with the parent pointer may not do the right thing. Notably, we need to keep the child in the left most slot there in case that is requested by the lookup. This is all pretty standard RCU stuff. It is worth repeating because in my eagerness to obey the radix tree node constructor scheme, I had broken it by zeroing the radix tree node before the grace period. What could happen is that a lookup can load the parent pointer, then decide it wants to follow the left most child slot, only to find the slot contained NULL due to the concurrent shrinker having zeroed the parent node before waiting for a grace period. The lookup would return a false negative as a result. Fix it by doing that clearing in the RCU callback. I would normally want to rip out the constructor entirely, but radix tree nodes are one of those places where they make sense (only few cachelines will be touched soon after allocation). This was never actually found in any lockless pagecache testing or by the test harness, but by seeing the odd problem with my scalable vmap rewrite. I have not tickled the test harness into reproducing it yet, but I'll keep working at it. Fortunately, it is not a problem anywhere lockless pagecache is used in mainline kernels (pagecache probe is not a guarantee, and brd does not have concurrent lookups and deletes).

It turned out this is because I use pnpacpi=off kernel option to work around the parport_pc bugs. I always did so, but RTC used to work fine in the past, and now it have regressed. The patch fixes the problem by creating the platform device for the RTC when PNP is disabled. This may also help running the PNP-enabled kernel on an older PCs.
