2011-08-11Bluetooth: rfcomm: Remove unnecessary krfcommd eventPeter Hurley
Removed superfluous event handling which was used to signal that the rfcomm kthread had been woken. This appears to have been used to prevent lost wakeups. Correctly ordering when the task state is set to TASK_INTERRUPTIBLE is sufficient to prevent lost wakeups. To prevent wakeups which occurred prior to initially setting TASK_INTERRUPTIBLE from being lost, the main work of the thread loop - rfcomm_process_sessions() - is performed prior to sleeping.

2011-08-11Bluetooth: btusb: be quiet on device disconnectPaul Bolle
Disabling the bluetooth usb device embedded in (some) ThinkPads tends to lead to errors like these: btusb_bulk_complete: hci0 urb ffff88011b9bfd68 failed to resubmit (19) btusb_intr_complete: hci0 urb ffff88011b46a318 failed to resubmit (19) btusb_bulk_complete: hci0 urb ffff88011b46a000 failed to resubmit (19) That is because usb_disconnect() doesn't "quiesces" pending urbs. Disconnecting a device is a normal thing to happen so it's no big deal that usb_submit_urb() returns -ENODEV. The simplest way to get rid of these errors is to stop treating that return as an error. Trivial, actually. While we're at it, add comments to be explicit about the reasons we're not complaining about -EPERM and -ENODEV.

2011-08-11move RLIMIT_NPROC check from set_user() to do_execve_common()Vasiliy Kulikov
The patch http://lkml.org/lkml/2003/7/13/226 introduced an RLIMIT_NPROC check in set_user() to check for NPROC exceeding via setuid() and similar functions. Before the check there was a possibility to greatly exceed the allowed number of processes by an unprivileged user if the program relied on rlimit only. But the check created new security threat: many poorly written programs simply don't check setuid() return code and believe it cannot fail if executed with root privileges. So, the check is removed in this patch because of too often privilege escalations related to buggy programs. The NPROC can still be enforced in the common code flow of daemons spawning user processes. Most of daemons do fork()+setuid()+execve(). The check introduced in execve() (1) enforces the same limit as in setuid() and (2) doesn't create similar security issues. Neil Brown suggested to track what specific process has exceeded the limit by setting PF_NPROC_EXCEEDED process flag. With the change only this process would fail on execve(), and other processes' execve() behaviour is not changed. Solar Designer suggested to re-check whether NPROC limit is still exceeded at the moment of execve(). If the process was sleeping for days between set*uid() and execve(), and the NPROC counter step down under the limit, the defered execve() failure because NPROC limit was exceeded days ago would be unexpected. If the limit is not exceeded anymore, we clear the flag on successful calls to execve() and fork(). The flag is also cleared on successful calls to set_user() as the limit was exceeded for the previous user, not the current one. Similar check was introduced in -ow patches (without the process flag). v3 - clear PF_NPROC_EXCEEDED on successful calls to set_user().

2011-08-11cifs: Do not set cifs/ntfs acl using a file handle (try #4)Shirish Pargaonkar
Set security descriptor using path name instead of a file handle. We can't be sure that the file handle has adequate permission to set a security descriptor (to modify DACL). Function set_cifs_acl_by_fid() has been removed since we can't be sure how a file was opened for writing, a valid request can fail if the file was not opened with two above mentioned permissions. We could have opted to add on WRITE_DAC and WRITE_OWNER permissions to file opens and then use that file handle but adding addtional permissions such as WRITE_DAC and WRITE_OWNER could cause an any open to fail. And it was incorrect to look for read file handle to set a security descriptor anyway. Signed-off-by: Shirish Pargaonkar <shirishpargaonkar@gmail.com> Signed-off-by: Steve French <sfrench@us.ibm.com>

pmbus_clear_faults() attempts to clear faults on non-existing real pages. As a result, the command error bit in the status register is set, and faults are not really cleared. All byte writes to non-zero pages are requests to clear the status register on that page. Since non-zero pages are virtual and do not exist on the chip, there is nothing to do, and such requests have to be ignored. This fixes above problem.

2011-08-11ipv4: some rt_iif -> rt_route_iif conversionsJulian Anastasov
As rt_iif represents input device even for packets coming from loopback with output route, it is not an unique key specific to input routes. Now rt_route_iif has such role, it was fl.iif in 2.6.38, so better to change the checks at some places to save CPU cycles and to restore 2.6.38 semantics. compare_keys: - input routes: only rt_route_iif matters, rt_iif is same - output routes: only rt_oif matters, rt_iif is not used for matching in __ip_route_output_key - now we are back to 2.6.38 state ip_route_input_common: - matching rt_route_iif implies input route - compared to 2.6.38 we eliminated one rth->fl.oif check because it was not needed even for 2.6.38 compare_hash_inputs: Only the change here is not an optimization, it has effect only for output routes. I assume I'm restoring the original intention to ignore oif, it was using fl.iif - now we are back to 2.6.38 state Signed-off-by: Julian Anastasov <ja@ssi.bg> Signed-off-by: David S.

2011-08-11slcan: ldisc generated skbs are received in softirq contextOliver Hartkopp
As this discussion pointed out http://marc.info/?l=linux-netdev&m=131257225602375 netdevices that are based on serial line disciplines should use netif_rx_ni() when pushing received socketbuffers into the netdev rx queue. Following commit 614851601c121b1320a35757ab88292d6272f906 ("slip: fix NOHZ local_softirq_pending 08 warning") this patch updates the slcan driver accordingly.

2011-08-11perf report: Use properly build_id kernel binariesJiri Olsa
If we bring the recorded perf data together with kernel binary from another machine using: on server A: perf archive on server B: tar xjvf perf.data.tar.bz2 -C ~/.debug the build_id kernel dso is not properly recognized during the "perf report" command on server B. The reason is, that build_id dsos are added during the session initialization, while the kernel maps are created during the sample event processing. The machine__create_kernel_maps functions ends up creating new dso object for kernel, but it does not check if we already have one added by build_id processing. Also the build_id reading ABI quirk added in commit: - commit b25114817a73bbd2b84ce9dba02ee1ef8989a947 perf build-id: Add quirk to deal with perf.data file format breakage populates the "struct build_id_event::pid" with 0, which is later interpreted as DEFAULT_GUEST_KERNEL_ID. This is not always correct, so it's better to guess the pid value based on the "struct build_id_event::header::misc" value. - Tested with data generated on x86 kernel version v2.6.34 and reported back on x86_64 current kernel. - Not tested for guest kernel case. Note the problem stays for PERF_RECORD_MMAP events recorded by perf that does not use proper pid (HOST_KERNEL_ID/DEFAULT_GUEST_KERNEL_ID). They are misinterpreted within the current perf code. Probably there's not much we can do about that.

2011-08-11block: improve rq_affinity placementShaohua Li
This patch reverts commit 35ae66e0a09ab70ed(block: Make rq_affinity = 1 work as expected). The purpose is to avoid an unnecessary IPI. Let's take an example. My test box has cpu 0-7, one socket. Say request is added from CPU 1, blk_complete_request() occurs at CPU 7. Without the reverted patch, softirq will be done at CPU 7. With it, an IPI will be directed to CPU 0, and softirq will be done at CPU 0. In this case, doing softirq at CPU 0 and CPU 7 have no difference from cache sharing point view and we can avoid an ipi if doing it in CPU 7. An immediate concern is this is just like QUEUE_FLAG_SAME_FORCE, but actually not. blk_complete_request() is running in interrupt handler, and currently I/O controller doesn't support multiple interrupts (I checked several LSI cards and AHCI), so only one CPU can run blk_complete_request(). This is still quite different as QUEUE_FLAG_SAME_FORCE. Since only one CPU runs softirq, the only difference with below patch is softirq not always runs at the first CPU of a group.

2011-08-11blktrace: add FLUSH/FUA supportNamhyung Kim
Add FLUSH/FUA support to blktrace. As FLUSH precedes WRITE and/or FUA follows WRITE, use the same 'F' flag for both cases and distinguish them by their (relative) position. The end results look like (other flags might be shown also): - WRITE: W - WRITE_FLUSH: FW - WRITE_FUA: WF - WRITE_FLUSH_FUA: FWF Note that we reuse TC_BARRIER due to lack of bit space of act_mask so that the older versions of blktrace tools will report flush requests as barriers from now on.

Using a gcc 4.4.3, warnings are emitted for a possibly uninitialized use of ecn_ok. This can happen if cookie_check_timestamp() returns due to not having seen a timestamp. Defaulting to ecn off seems like a reasonable thing to do in this case, so initialized ecn_ok to false. Signed-off-by: Mike Waychison <mikew@google.com> Signed-off-by: David S.
