3790ee4 Eric W. Biederman 10 December 2007, 23:49:36 UTC proc: remove/Fix proc generic d_revalidate Ultimately to implement /proc perfectly we need an implementation of d_revalidate because files and directories can be removed behind the back of the VFS, and d_revalidate is the only way we can let the VFS know that this has happened. Unfortunately the linux VFS can not cope with anything in the path to a mount point going away. So a proper d_revalidate method that calls d_drop also needs to call have_submounts which is moderately expensive, so you really don't want a d_revalidate method that unconditionally calls it, but instead only calls it when the backing object has really gone away. proc generic entries only disappear on module_unload (when not counting the fledgling network namespace) so it is quite rare that we actually encounter that case and has not actually caused us real world trouble yet. So until we get a proper test for keeping dentries in the dcache fix the current d_revalidate method by completely removing it. This returns us to the current status quo. So with CONFIG_NETNS=n things should look as they have always looked. For CONFIG_NETNS=y things work most of the time but there are a few rare corner cases that don't behave properly. As the network namespace is barely present in 2.6.24 this should not be a problem. Signed-off-by: Eric W. Biederman <ebiederm@xmission.com> Cc: "Rafael J.

d84248b Rini van Zetten 10 December 2007, 23:49:34 UTC atmel_spi: reload RCR before TCR We have a wifi module connected to the spi bus and got sometimes FIFO overrun errors on the spi bus. After some investigation i found that the driver loads the TCR (transmit count) register before the RCR (receive count). When the transfer list is not empty the atmel_spi_next_message is called while tx and rx are enabled. As soon as the TCR is loaded, hardware starts transfer and causes a rx fifo overrun because the RCR is not loaded yet. Load the RCR before the TCR. After this patch the fifo overrun disapears at out setup.

522939d Maciej W. Rozycki 10 December 2007, 23:49:31 UTC esp_scsi: fix reset cleanup spinlock recursion The esp_reset_cleanup() function is called with the host lock held and invokes starget_for_each_device() which wants to take it too. Here is a fix along the lines of shost_for_each_device()/__shost_for_each_device() adding a __starget_for_each_device() counterpart which assumes the lock has already been taken. Eventually, I think the driver should get modified so that more work is done as a softirq rather than in the interrupt context, but for now it fixes a bug that causes the spinlock debugger to fire. While at it, it fixes a small number of cosmetic problems with starget_for_each_device() too. Signed-off-by: Maciej W. Rozycki <macro@linux-mips.org> Acked-by: David S.

72fad71 Adam Litke 10 December 2007, 23:49:28 UTC hugetlb: handle write-protection faults in follow_hugetlb_page The follow_hugetlb_page() fix I posted (merged as git commit 5b23dbe8173c212d6a326e35347b038705603d39) missed one case. If the pte is present, but not writable and write access is requested by the caller to get_user_pages(), the code will do the wrong thing. Rather than calling hugetlb_fault to make the pte writable, it notes the presence of the pte and continues. This simple one-liner makes sure we also fault on the pte for this case. Please apply.

a186b4a Jarod Wilson 03 December 2007, 18:43:12 UTC firewire: OHCI 1.0 Isochronous Receive support Third rendition of FireWire OHCI 1.0 Isochronous Receive support, using a zer-copy method similar to OHCI 1.1 which puts the IR data payload directly into the userspace buffer. The zero-copy implementation eliminates the video artifacts, audio popping, and buffer underrun problems seen with version 1 of this patch, as well as fixing a regression in OHCI 1.1 support introduced by version 2 of this patch. Successfully tested in OHCI 1.1 mode on the following chipsets: - NEC uPD72847 (rev 01), OHCI 1.1 (PCI) - Ti XIO2200(A) (rev 01), OHCI 1.1 (PCIe) - Ti TSB41AB2 (rev 01), OHCI 1.1 (PCI on SB Audigy) - Apple UniNorth 2 (rev 81), OHCI 1.1 (PowerBook G4 onboard) Successfully tested in OHCI 1.0 mode on the following chipsets: - Agere FW323 (rev 06), OHCI 1.0 (Mac Mini onboard) - Agere FW323 (rev 06), OHCI 1.0 (PCI) - Via VT6306 (rev 46), OHCI 1.0 (PCI) - NEC OrangeLink (rev 01), OHCI 1.0 (PCI) - NEC uPD72847 (rev 01), OHCI 1.1 (PCI) - Ti XIO2200(A) (rev 01), OHCI 1.1 (PCIe) The bulk of testing was done in an x86_64 system, but was also successfully sanity-tested on other systems, including a PPC(32) PowerBook G4 and an i686 EPIA M10k. Crude benchmarking (watching top during capture) puts the cpu utilization during capture on the EPIA's 1GHz Via C3 processor around 13%, which is down from 30% with the v1 code. Some implementation details: To maintain the same userspace API as dual-buffer mode, we set up two descriptors for every incoming packet. The first is an INPUT_MORE descriptor, pointing to a buffer large enough to hold just the packet's iso headers, immediately followed by an INPUT_LAST descriptor, pointing to a chunk of the userspace buffer big enough for the packet's data payload. With this setup, each incoming packet fills in these two descriptors in a manner that very closely emulates dual-buffer receive, to the point where the bulk of the handle_ir_* code is now identical between the two (and probably primed for some restructuring to share code between them). The only caveat I have at the moment is that neither of my OHCI 1.0 Via VT6307-based FireWire controllers work particularly well with this code for reasons I have yet to figure out.

a743084 David Chinner 23 November 2007, 05:30:23 UTC [XFS] Fix broken inode cluster setup. The radix tree based inode caches did away with the inode cluster hashes, replacing them with a bunch of masking and gang lookups on the radix tree. This masking got broken when moving the code to per-ag radix trees and indexing by agino # rather than straight inode number. The result is clustered inode writeback does not cluster and things can go extremely slowly when there are lots of inodes to write.

cd57e59 Lachlan McIlroy 23 November 2007, 05:30:32 UTC [XFS] 971064 Various fixups for xfs_bulkstat(). - sanity check for NULL user buffer in xfs_ioc_bulkstat[_compat]() - remove the special case for XFS_IOC_FSBULKSTAT with count == 1. This special case causes bulkstat to fail because the special case uses xfs_bulkstat_single() instead of xfs_bulkstat() and the two functions have different semantics. xfs_bulkstat() will return the next inode after the one supplied while skipping internal inodes (ie quota inodes). xfs_bulkstate_single() will only lookup the inode supplied and return an error if it is an internal inode. - in xfs_bulkstat(), need to initialise 'lastino' to the inode supplied so in cases were we return without examining any inodes the scan wont restart back at zero. - sanity check for valid *ubcountp values. Cannot sanity check for valid ubuffer here because some users of xfs_bulkstat() don't supply a buffer. - checks against 'ubleft' (the space left in the user's buffer) should be against 'statstruct_size' which is the supplied minimum object size. The mixture of checks against statstruct_size and 0 was one of the reasons we were skipping inodes. - if the formatter function returns BULKSTAT_RV_NOTHING and an error and the error is not ENOENT or EINVAL then we need to abort the scan. ENOENT is for inodes that are no longer valid and we just skip them. EINVAL is returned if we try to lookup an internal inode so we skip them too. For a DMF scan if the inode and DMF attribute cannot fit into the space left in the user's buffer it would return ERANGE. We didn't handle this error and skipped the inode. We would continue to skip inodes until one fitted into the user's buffer or we completed the scan. - put back the recalculation of agino (that got removed with the last fix) at the end of the while loop. This is because the code at the start of the loop expects agino to be the last inode examined if it is non-zero. - if we found some inodes but then encountered an error, return success this time and the error next time. If the formatter aborted with ENOMEM we will now return this error but only if we couldn't read any inodes. Previously if we encountered ENOMEM without reading any inodes we returned a zero count and no error which falsely indicated the scan was complete.

Jan Altenberg <jan.altenberg@linutronix.de> reported that building with redirected input like this failed: make O=dir oldconfig bzImage < /dev/null The problem were caused by a make silentoldconfig being run before oldconfig and with a non-recent .config the build failed because silentoldconfig requires non-redirected stdin. Silentoldconfig was run as a side-effect of having the top-level Makefile re-made by make. Introducing an empty rule for the top-level Makefile (and Kbuild.include) fixed the issue.

459ad68 Tejun Heo 07 December 2007, 03:46:23 UTC libata: kill spurious NCQ completion detection Spurious NCQ completion detection implemented in ahci was incorrect. On AHCI receving and processing FISes and raising interrupts are not interlocked and spurious interrupts are expected. For example, if an interrupt occurs while interrupt handler is running and the running interrupt handler handles the event the new IRQ indicated, after IRQ handler finishes, it will be executed again because IRQ pending bit is set by the new interrupt but there won't be anything to process. Please read the following message for more information. http://article.gmane.org/gmane.linux.ide/26012 This patch... * Removes all spurious IRQ whining from ahci. Spurious NCQ completion detection was completely wrong. Spurious D2H Register FIS taught us that some early drives send spurious D2H Register FIS with I bit set while NCQ commands are in progress but none of recent drives does that and even the ones which show such behavior can do NCQ fine. * Kills all NCQ blacklist entries which were added because of spurious NCQ completions. I tracked down each commit and verified all removed ones are actually added because of spurious completions. WD740ADFD-00NLR1 wasn't deleted but moved upward because the drive not only had spurious NCQ completions but also is slow on sequential data transfers if NCQ is enabled. Maxtor 7V300F0 was added by 0e3dbc01d53940fe10e5a5cfec15ede3e929c918 from Alan Cox. I can only find evidences that the drive only had troubles with spuruious completions by searching the mailing list. This entry needs to be verified and removed if it doesn't have other NCQ related problems.

Originally submitted by "Glenn Griffin" <ggriffin.kernel@gmail.com>; modified by Jay Vosburgh to move setting of hash policy out of line, tweak the documentation update and add version update to 3.2.2. Glenn's original comment follows: Included is a patch for a new xmit_hash_policy for the bonding driver that selects slaves based on MAC and IP information. This is a middle ground between what currently exists in the layer2 only policy and the layer3+4 policy. This policy strives to be fully 802.3ad compliant by transmitting every packet of any particular flow over the same link. As documented the layer3+4 policy is not fully compliant for extreme cases such as ip fragmentation, so this policy is a nice compromise for environments that require full compliance but desire more than the layer2 only policy.

62f0f61 Thomas Gleixner 07 December 2007, 18:16:17 UTC hrtimers: avoid overflow for large relative timeouts Relative hrtimers with a large timeout value might end up as negative timer values, when the current time is added in hrtimer_start(). This in turn is causing the clockevents_set_next() function to set an huge timeout and sleep for quite a long time when we have a clock source which is capable of long sleeps like HPET. With PIT this almost goes unnoticed as the maximum delta is ~27ms. The non-hrt/nohz code sorts this out in the next timer interrupt, so we never noticed that problem which has been there since the first day of hrtimers. This bug became more apparent in 2.6.24 which activates HPET on more hardware.

68ca3e5 Haavard Skinnemoen 03 December 2007, 17:04:11 UTC [AVR32] Fix copy_to_user_page() breakage The current implementation of copy_to_user_page() gives "vaddr" to the cache instruction when trying to sync the icache with the dcache. If vaddr does not exist in the TLB, the CPU will silently abort the operation, which may result in the caches staying out of sync. To fix this, pass the "dst" parameter to flush_icache_range() instead -- we know this is valid because we just wrote to it.

2507bc1 Haavard Skinnemoen 28 November 2007, 14:04:01 UTC [AVR32] Follow the rules when dealing with the OCD system The current debug trap handling code does a number of things that are illegal according to the AVR32 Architecture manual. Most importantly, it may try to schedule from Debug Mode, thus clearing the D bit, which can lead to "undefined behaviour". It seems like this works in most cases, but several people have observed somewhat unstable behaviour when debugging programs, including soft lockups. So there's definitely something which is not right with the existing code. The new code will never schedule from Debug mode, it will always exit Debug mode with a "retd" instruction, and if something not running in Debug mode needs to do something debug-related (like doing a single step), it will enter debug mode through a "breakpoint" instruction. The monitor code will then return directly to user space, bypassing its own saved registers if necessary (since we don't actually care about the trapped context, only the one that came before.) This adds three instructions to the common exception handling code, including one branch. It does not touch super-hot paths like the TLB miss handler.

8dfe8f2 Haavard Skinnemoen 27 November 2007, 12:31:20 UTC [AVR32] Clean up OCD register usage Generate a new set of OCD register definitions in asm/ocd.h and rename __mfdr() and __mtdr() to ocd_read() and ocd_write() respectively. The bitfield definitions are a lot more complete now, and they are entirely based on bit numbers, not masks. This is because OCD registers are frequently accessed from assembly code, where bit numbers are a lot more useful (can be fed directly to sbr, bfins, etc.) Bitfields that consist of more than one bit have two definitions: _START, which indicates the number of the first bit, and _SIZE, which indicates the number of bits. These directly correspond to the parameters taken by the bfextu, bfexts and bfins instructions. Signed-off-by: Haavard Skinnemoen <hskinnemoen@atmel.com> 07 December 2007, 13:54:40 UTC
