This allows the removal of some #ifdefs. (2) #ifdef'ing out the contents of slow_work_wait_for_items() in moduleless kernels. The four functions related to handling module unloading synchronisation (and their associated variables) could be offloaded into a separate .c file, but each function is only used once and three of them are tiny, so doing so would prevent them from being inlined.

| 199bc9f | David Woodhouse | 30 November 2009, 09:06:40 UTC | jffs2: Fix memory corruption in jffs2_read_inode_range() In 2.6.23 kernel, commit a32ea1e1f925399e0d81ca3f7394a44a6dafa12c ("Fix read/truncate race") fixed a race in the generic code, and as a side effect, now do_generic_file_read() can ask us to readpage() past the i_size. This seems to be correctly handled by the block routines (e.g. block_read_full_page() fills the page with zeroes in case if somebody is trying to read past the last inode's block). JFFS2 doesn't handle this; it assumes that it won't be asked to read pages which don't exist -- and thus that there will be at least _one_ valid 'frag' on the page it's being asked to read. It will fill any holes with the following memset: memset(buf, 0, min(end, frag->ofs + frag->size) - offset); When the 'closest smaller match' returned by jffs2_lookup_node_frag() is actually on a previous page and ends before 'offset', that results in: memset(buf, 0, <huge unsigned negative>); Hopefully, in most cases the corruption is fatal, and quickly causing random oopses, like this: root@10.0.0.4:~/ltp-fs-20090531# ./testcases/kernel/fs/ftest/ftest01 Unable to handle kernel paging request for data at address 0x00000008 Faulting instruction address: 0xc01cd980 Oops: Kernel access of bad area, sig: 11 [#1] [...] NIP [c01cd980] rb_insert_color+0x38/0x184 LR [c0043978] enqueue_hrtimer+0x88/0xc4 Call Trace: [c6c63b60] [c004f9a8] tick_sched_timer+0xa0/0xe4 (unreliable) [c6c63b80] [c0043978] enqueue_hrtimer+0x88/0xc4 [c6c63b90] [c0043a48] __run_hrtimer+0x94/0xbc [c6c63bb0] [c0044628] hrtimer_interrupt+0x140/0x2b8 [c6c63c10] [c000f8e8] timer_interrupt+0x13c/0x254 [c6c63c30] [c001352c] ret_from_except+0x0/0x14 --- Exception: 901 at memset+0x38/0x5c LR = jffs2_read_inode_range+0x144/0x17c [c6c63cf0] [00000000] (null) (unreliable) This patch fixes the issue, plus fixes all LTP tests on NAND/UBI with JFFS2 filesystem that were failing since 2.6.23 (seems like the bug above also broke the truncation).

As the comment indicates, the BUG_ON can be removed since the ampdu_action callback must already exist when the state is != IDLE. The second problem isn't easily exploitable but there's a race condition due to unconditionally setting the state to OPERATIONAL when a delBA frame is received, even when no aggregation session was ever initiated. All the drivers accept stopping the session even then, but that opens a race window where crashes could happen before the driver accepts it. Right now, a WARN_ON may happen with non-HT drivers, while the race opens only for HT drivers. For this case, there are two things necessary to fix it: 1) don't process spurious delBA frames, and be more careful about the session state; don't drop the lock 2) HT drivers need to be prepared to handle a session stop even before the session was really started -- this is true for all drivers (that support aggregation) but iwlwifi which can be fixed easily. The other HT drivers (ath9k and ar9170) are behaving properly already.

However, d280ead changed this to checking for non-zero resource flags. Unfortunately, this means that on some platforms, we end up passing '-1' to request_irq rather than the desired result. Combine the two conditions into one so that the IRQ flags are taken from the resource if either SMC_IRQ_FLAGS is -1 or the resource flags specify an interrupt trigger.

There's no reason to go through a pair of enable/disable cycles when acquiring and releasing the parent's lock. In __pm_runtime_set_status(), irqs are already disabled when the parent's lock is acquired, and they must remain disabled when it is released.

| 5fdd4ba | Andrei Pelinescu-Onciul | 29 November 2009, 08:14:02 UTC | sctp: on T3_RTX retransmit all the in-flight chunks When retransmitting due to T3 timeout, retransmit all the in-flight chunks for the corresponding transport/path, including chunks sent less then 1 rto ago. This is the correct behaviour according to rfc4960 section 6.3.3 E3 and "Note: Any DATA chunks that were sent to the address for which the T3-rtx timer expired but did not fit in one MTU (rule E3 above) should be marked for retransmission and sent as soon as cwnd allows (normally, when a SACK arrives). ". This fixes problems when more then one path is present and the T3 retransmission of the first chunk that timeouts stops the T3 timer for the initial active path, leaving all the other in-flight chunks waiting forever or until a new chunk is transmitted on the same path and timeouts (and this will happen only if the cwnd allows sending new chunks, but since cwnd was dropped to MTU by the timeout => it will wait until the first heartbeat). Example: 10 packets in flight, sent at 0.1 s intervals on the primary path. The primary path is down and the first packet timeouts. The first packet is retransmitted on another path, the T3 timer for the primary path is stopped and cwnd is set to MTU. All the other 9 in-flight packets will not be retransmitted (unless more new packets are sent on the primary path which depend on cwnd allowing it, and even in this case the 9 packets will be retransmitted only after a new packet timeouts which even in the best case would be more then RTO). This commit reverts d0ce92910bc04e107b2f3f2048f07e94f570035d and also removes the now unused transport->last_rto, introduced in b6157d8e03e1e780660a328f7183bcbfa4a93a19. p.s The problem is not only when multiple paths are there. It can happen in a single homed environment. If the application stops sending data, it possible to have a hung association.

We delay the adding until all scans have completed to retain the same ordering as sync scanning. This delay in visibility causes an oops if a device is removed before we make it visible because the SCSI removal routines have an inbuilt assumption that if a device is in SDEV_RUNNING state, it must be visible (which is not necessarily true in the async scanning case). Fix this by introducing an additional is_visible flag which we can use to condition the tear down so we do the right thing for running but not yet made visible.

This prevents setting DMA mode to any other value than the default (maximum) supported by the device (or UDMA6, if supported) irrespective of the actual requested transfer mode and returns error. For example, setting mode to UDMA2 using hdparm, where UDMA4 is the default transfer mode gives following error: # ./hdparm -d1 -Xudma2 /dev/hda /dev/hda:hda: UDMA/66 mode selected setting using_dma to 1 (on) hda: UDMA/66 mode selected setting xfermode to 66 (UltraDMA mode2) HDIO_DRIVE_CMD(setxfermode) failed: Invalid argument using_dma = 1 (on) This patch fixes the issue.

| 275014a | Henrique de Moraes Holschuh | 17 November 2009, 22:07:22 UTC | thinkpad-acpi: fix detection of old ThinkPads There is a problem in the quirk tables used by tpacpi_is_fw_known() and tpacpi_check_outdated_fw(), which causes outdated BIOSes that are lacking the EC firmware ID DMI field to never match. This breaks module loading on, e.g. a T23 with outdated BIOS, and the module will refuse to load unless the "force_load=1" parameter is given. Fix the quirk tables so that they can also match the outdated BIOSes, which in turn will both fix the module loading, and also warn the user that he is using outdated firmware and should upgrade. This fixes a serious regression, introduced by commit e675abafcc0df38125e6e94a9ba91c92fe774f52, "thinkpad-acpi: be more strict when detecting a ThinkPad". http://bugzilla.kernel.org/show_bug.cgi?id=14597 Reported-by: Paul Kimoto <kimoto@lightlink.com> Signed-off-by: Henrique de Moraes Holschuh <hmh@hmh.eng.br> Tested-by: Paul Kimoto <kimoto@lightlink.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> Signed-off-by: Len Brown <len.brown@intel.com> | 25 November 2009, 05:42:15 UTC |

| cea6234 | Steve French | 24 November 2009, 22:49:37 UTC | [CIFS] Duplicate data on appending to some Samba servers SMB writes are sent with a starting offset and length. When the server supports the newer SMB trans2 posix open (rather than using the SMB NTCreateX) a file can be opened with SMB_O_APPEND flag, and for that case Samba server assumes that the offset sent in SMBWriteX is unneeded since the write should go to the end of the file - which can cause problems if the write was cached (since the beginning part of a page could be written twice by the client mm). Jeff suggested that masking the flag on posix open on the client is easiest for the time being. Note that recent Samba server also had an unrelated problem with SMB NTCreateX and append (see samba bugzilla bug number 6898) which should not affect current Linux clients (unless cifs Unix Extensions are disabled). The cifs client did not send the O_APPEND flag on posix open before 2.6.29 so the fix is unneeded on early kernels. In the future, for the non-cached case (O_DIRECT, and forcedirectio mounts) it would be possible and useful to send O_APPEND on posix open (for Windows case: FILE_APPEND_DATA but not FILE_WRITE_DATA on SMB NTCreateX) but for cached writes although the vfs sets the offset to end of file it may fragment a write across pages - so we can't send O_APPEND on open (could result in sending part of a page twice).
