2006-09-17ieee1394: sbp2: convert sbp2util_down_timeout to waitqueueStefan Richter
The waitqueue API is used to replace a custom wait mechanism. Only one global waitqueue (instead of per-device waitqueues or completions) is added because there is usually just one waiter. Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de>
2006-09-17ieee1394: sbp2: more checks of status blockStefan Richter
- Add checks for the (very unlikely) cases that the target writes too little or too much status data or writes unsolicited status. - Indicate that these and similar conditions are unlikely(). - Check the 'resp' and 'sbp_status' fields for possible failure status. - Slightly optimize access macros for the status block bitfields. - Unify a few related log messages. TODO: Check if 'src'==1, then withhold the respective ORB from reuse until status for any subsequent ORB was received. This is an old bug whose fix requires more complex command queue handling.

2006-09-17ieee1394: sbp2: safer initialization of status fifoStefan Richter
Sbp2's copy of the status fifo was cleared when management ORBs or new command ORBs were prepared. The latter had potential for a race condition if the block layer's soft IRQ and the 1394 LLD's interrupt handler ran on different CPUs. It would also yield wrong status if a command was completed with non-zero completion status before other commands that had zero completion status, and no new command was enqueued in the meantime. Now, the status buffer is cleared right before it is written. Thus it ends up in the following simpler and safer access pattern: - sbp2_alloc_device: allocates and implicitly clears once, - sbp2_handle_status_write: clears, writes, and reads, - sbp2_query_logins, sbp2_login_device, sbp2_reconnect_device: read. The latter three do not race with sbp2_handle_status_write because of how the protocol works. As a tiny optimization, the first two quadlets of the status never need to be cleared.

2006-09-17ieee1394: sbp2: optimize DMA direction of command ORBsStefan Richter
Only the driver writes ORBs, the device just reads them. Therefore PCI_DMA_BIDIRECTIONAL can be replaced by PCI_DMA_TODEVICE which may be cheaper on some architectures. Signed-off-by: Stefan Richter <stefanr@s5r6.in-berlin.de>
2006-09-17ieee1394: sbp2: discard return value of sbp2_link_orb_commandStefan Richter

2006-09-17ieee1394: sbp2: safer last_orb and next_ORB handlingStefan Richter
The sbp2 initiator has two ways to tell a target's fetch agent about new command ORBs: - Write the ORB's address to the ORB_POINTER register. This must not be done while the fetch agent is active. - Put the ORB's address into the previously submitted ORB's next_ORB field and write to the DOORBELL register. This may be done while the fetch agent is active or suspended. It must not be done while the fetch agent is in reset state. Sbp2 has a last_orb pointer which indicates in what way a new command should be announced. That pointer is concurrently accessed at various occasions. Furthermore, initiator and target are accessing the next_ORB field of ORBs concurrently and asynchronously. This patch does: - Protect all initiator accesses to last_orb by sbp2_command_orb_lock. - Add pci_dma_sync_single_for_device before a previously submitted ORB's next_ORB field is overwritten. - Insert a memory barrier between when next_ORB_lo and next_ORB_hi are overwritten. Next_ORB_hi must not be updated before next_ORB_lo. - Remove the rather unspecific and now superfluous qualifier "volatile" from the next_ORB fields. - Add comments on how last_orb is connected with what is known about the target's fetch agent's state.

2006-09-17ieee1394: shrink tlabel pools, remove tpool semaphoresStefan Richter
This patch reduces the size of struct hpsb_host and also removes semaphores from ieee1394_transactions.c. On i386, struct hpsb_host shrinks from 10656 bytes to 6688 bytes. This is accomplished by - using a single wait_queue for hpsb_get_tlabel instead of many instances of semaphores, - using a single lock to serialize access to all tlabel pools (the protected code regions are small, i.e. lock contention very low), - omitting the sysfs attribute tlabels_allocations. Drawback: In the rare case that a process needs to sleep because all transaction labels for the node are temporarily exhausted, it is also woken up if a tlabel for a different node became free, checks for an available tlabel, and is put to sleep again. The check is not costly and the situation occurs extremely rarely. (Tlabels are typically only exhausted if there was no context switch to the khpsbpkt thread which recycles tlables.) Therefore the benefit of reduced tpool size outweighs this drawback. The sysfs attributes tlabels_free and tlabels_mask are not compiled anymore unless CONFIG_IEEE1394_VERBOSEDEBUG is set. The by far biggest member of struct hpsb_host, the struct csr_control csr (5272 bytes on i386), is now placed at the end of struct hpsb_host. Note, hpsb_get_tlabel calls the macro wait_event_interruptible with a condition argument which has a side effect (allocation of a tlabel and manipulation of the packet). This side effect happens only if the condition is true. The patch relies on wait_event_interruptible not evaluating the condition again after it became true.

[PATCH 6/9] s390: qeth driver fixes [3/6] From: Frank Pavlic <fpavlic@de.ibm.com> fixed kernel panic caused by qeth driver: Using a bonding device qeth driver will realloc headroom for every skb coming from the bond device. Once this happens qeth frees the original skb and set the skb pointer to the new realloced skb. Under heavy transmit workload (e.g.UDP streams) through bond network device the qdio output queue might get full. In this case we return with EBUSY from qeth_send_packet. Returning to qeth_hard_start_xmit routine the skb address on the stack still points to the old address, which has been freed before. Returning from qeth_hard_start_xmit with EBUSY results in requeuing the skb. In this case it corrupts the qdisc queue and results in kernel panic.

2006-09-16[PATCH] headers_check: use a different default directoryDavid Woodhouse
`make headers_check' wants to go and write stuff in /lib/modules, which requires root, whic is unfortunate. In fact, there's no _particular_ reason for headers_install to put it there either -- it can go into a subdirectory of the build tree in both cases. It's not intended to go directly into /usr/include, which is why we didn't put it there -- and we certainly don't want people screwing around with symlinking to it. It's for distributors to take away and do stuff with, so leaving it in $(objtree) is fine, even in the headers_install case. I picked $(objtree)/usr/include but I have no _particular_ preference for that; it just seemed reasonable.

2006-09-16[PATCH] Fix 'make headers_check' for AlphaDavid Woodhouse
Alpha currently fails 'make headers_check' in the 2.6.18-rc kernels. This patch fixes it, by moving the existing #ifdef __KERNEL__ in asm/page.h so that it covers everything that userspace shouldn't so, and by adding asm/compiler.h to the list of exported files so that its use within asm/byteorder.h is successful. [ Note that at least with GCC 4, <linux/compiler.h> doesn't do the forced inlining about which there are nasty comments (and a workaround) in <asm/compiler.h>, unless you set CONFIG_FORCED_INLINING. Rather than keep the mess you have in <asm/compiler.h> you could perhaps just make sure CONFIG_FORCED_INLINING=n is also honoured with GCC3, and make sure it cannot be set for Alpha? ] Signed-off-by: David Woodhouse <dwmw2@infradead.org> Cc: Sam Ravnborg <sam@ravnborg.org> Cc: Ivan Kokshaysky <ink@jurassic.park.msu.ru> Cc: Richard Henderson <rth@twiddle.net> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>

We generate an <asm/foo.h> which includes either <asm-$ARCH/foo.h> or <asm-$ALTARCH/foo.h> as appropriate. But we were doing this dependent on whether the file in question existed in the _unexported_ tree, not the exported tree. So if a file was exported to userspace in one asm- directory but not the other, the generated file in asm/ was incorrect. This only changed the failure mode if it _was_ included from a nice #error to a less explicable #include failure -- but it also gave false errors in 'make headers_check' output.

2006-09-14IB/srp: Don't schedule reconnect from srpIshai Rabinovitz
If there is a problem in the connection, the SCSI mid-layer will eventually call srp_reset_host(), which will call srp_reconnect(), so we do not need to schedule a call to srp_reconnect_work() from srp_completion(). Removing this prevents srp_reset_host() from failing if a reconnect scheduled from srp_completion() is already in progress, which in turn was causing crashes as both SCSI midlayer and srp_reconnect() were cancelling commands.

2006-09-13[PATCH] cciss: version update, new hwMike Miller
Add support for new hardware and bumps the version to 3.6.10. It seems there were several changes introduced including soft_irq. I decided to bump the major number to reflect these changes. Since we're still supporting older vendor kernels I need some way differentiate between kernel versions <=2.6.10 and newer kernels >=2.6.16.

2006-09-13[PATCH] headers_check: fix userspace build of asm-mips/page.hDavid Woodhouse
MIPS asm/page.h unconditionally includes <asm-generic/memory_model.h>, which doesn't exist in userspace. Move an #endif /* __KERNEL__ */ down a few lines to prevent that. Also, remove the broken definition of PAGE_SIZE which is never going to be correct -- in the absence of PAGE_SIZE, non-broken userspace will fall back to using sysconf() or getpagesize() instead.
