e89a5a4 Trond Myklebust 31 August 2007, 14:45:17 UTC NFS: Fix the mount regression This avoids the recent NFS mount regression (returning EBUSY when mounting the same filesystem twice with different parameters). The best I can do given the constraints appears to be to have the kernel first look for a superblock that matches both the fsid and the user-specified mount options, and then spawn off a new superblock if that search fails. Note that this is not the same as specifying nosharecache everywhere since nosharecache will never attempt to match an existing superblock.

36ad488 Linus Torvalds 01 September 2007, 03:18:51 UTC x86: be even more careful about checking the stack frame on dumping lguest didn't initialize the kernel stack the way a real i386 kernel does, and ended up triggering a corner-case in the stack frame checking that doesn't happen on naive i386, and that the stack dumping didn't handle quite right. This makes the frame handling more correct, and tries to clarify the code at the same time so that it's a bit more obvious what is going on.

3b2b64f Linus Torvalds 01 September 2007, 03:13:57 UTC Do not use the ia64 clocksource on non-ia64 architectures The HPET clocksource in drivers/char/hpet.c was written as generic code for ia64, but it is not yet ready to replace the native HPET clocksource implementations that the i386/x86-64 architectures use. On x86[-64], trying to register this clocksource results in potentially multiple hpet-based clocksources being registered, and if the ia64 one is chosen on x86_64 some users have experienced hangs. Eventually all three architectures may end up using the same code, but that is not the case right now.

A network interface can get ARP packets even when the interface has NOARP specified. In a HiperSockets environment this disturbs receiving systems when packets are sent on the multicast queue. (E.g.

d0a34f9 Ursula Braun 29 August 2007, 09:26:52 UTC qeth: ungrouping a device must not be interruptible Problem: A recovery thread must not be active when device is removed. In qeth_remove_device() an interruptible wait operation is used to wait until a qeth recovery thread is finished. If a user really interrupts the ungroup operation of a qeth device while a recovery is running, cio and qeth are out of sync (device already removed from cio, but kept in qeth). A following module unload of qeth results in a kernel OOPS here. Solution: Do not allow interruption of ungroup operation to guarantee finishing of a potentially running qeth recovery thread.

The IOC3 driver's UART detection bits used to rely on the the firmware setting the UART pre-divider in a way that's apropriate for the 8250 driver which doesn't currently program this register. This happens to work for the console but not rarely for additional ports. While at it, also program the UART to RS-232 PIO mode; it the UART might have been in mac-serial and/or DMA mode though that hasn't actually been observed in practice.

dec4ad8 David Gibson 31 August 2007, 06:56:40 UTC hugepage: fix broken check for offset alignment in hugepage mappings For hugepage mappings, the file offset, like the address and size, needs to be aligned to the size of a hugepage. In commit 68589bc353037f233fe510ad9ff432338c95db66, the check for this was moved into prepare_hugepage_range() along with the address and size checks. But since BenH's rework of the get_unmapped_area() paths leading up to commit 4b1d89290b62bb2db476c94c82cf7442aab440c8, prepare_hugepage_range() is only called for MAP_FIXED mappings, not for other mappings. This means we're no longer ever checking for an aligned offset - I've confirmed that mmap() will (apparently) succeed with a misaligned offset on both powerpc and i386 at least. This patch restores the check, removing it from prepare_hugepage_range() and putting it back into hugetlbfs_file_mmap(). I'm putting it there, rather than in the get_unmapped_area() path so it only needs to go in one place, than separately in the half-dozen or so arch-specific implementations of hugetlb_get_unmapped_area().

60187d2 Oleg Nesterov 31 August 2007, 06:56:35 UTC sigqueue_free: fix the race with collect_signal() Spotted by taoyue <yue.tao@windriver.com> and Jeremy Katz <jeremy.katz@windriver.com>. collect_signal: sigqueue_free: list_del_init(&first->list); if (!list_empty(&q->list)) { // not taken } q->flags &= ~SIGQUEUE_PREALLOC; __sigqueue_free(first); __sigqueue_free(q); Now, __sigqueue_free() is called twice on the same "struct sigqueue" with the obviously bad implications. In particular, this double free breaks the array_cache->avail logic, so the same sigqueue could be "allocated" twice, and the bug can manifest itself via the "impossible" BUG_ON(!SIGQUEUE_PREALLOC) in sigqueue_free/send_sigqueue. Hopefully this can explain these mysterious bug-reports, see http://marc.info/?t=118766926500003 http://marc.info/?t=118466273000005 Alexey Dobriyan reports this patch makes the difference for the testcase, but nobody has an access to the application which opened the problems originally.

This shows that a driver's irq handler was running both in hard interrupt and process contexts with irqs enabled. The latter was done during free_irq() call and was possible only with CONFIG_DEBUG_SHIRQ enabled. This was fixed by another patch. But similar problem is possible with request_irq(): any locks taken from irq handler could be vulnerable - especially with soft interrupts. This patch fixes it by disabling local interrupts during handler's run. (It seems, disabling softirqs should be enough, but it needs more checking on possible races or other special cases).

fc3ba95 David Brownell 31 August 2007, 06:56:24 UTC SPI driver hotplug/coldplug fixes Update various SPI drivers so they properly support - coldplug through "modprobe $(cat /sys/devices/.../modalias)" - hotplug through "modprobe $(MODALIAS)" The basic rule for platform, SPI, and (new style) I2C drivers is just to make sure that modprobing the driver name works. In this case, all the relevant drivers are platform drivers, and this patch either (a) Changes the driver name, if no in-tree code would break; this is simpler and thus preferable in the long term. (b) Adds MODULE_ALIAS directives, when in-tree platforms declare devices using the current driver name; less desirable. Most systems will link SPI controller drivers statically, but there's no point in being needlessly broken.

62e6f1e Hugh Dickins 31 August 2007, 03:26:50 UTC fix maxcpus=1 oops in show_stat() Alexey Dobriyan reports that maxcpus=1 is still broken in 2.6.23-rc4: if CONFIG_HOTPLUG_CPU is not set, x86_64 bootup oopses in show_stat() - for_each_possible_cpu accesses a per-cpu area which was never set up. Alexey identified commit 61ec7567db103d537329b0db9a887db570431ff4 (ACPI: boot correctly with "nosmp" or "maxcpus=0") as the origin; but it's not really to blame, just exposes a bug in 2.6.23-rc1's commit 8b3b295502444340dd0701855ac422fbf32e161d (Especially when !CONFIG_HOTPLUG_CPU, avoid needlessy allocating resources for CPUs that can never become available). rc1's test for max_cpus < 2 in start_kernel() wasn't working because max_cpus was still NR_CPUS at that point: until rc4 moved the maxcpus parsing earlier. Now it sets cpu_possible_map to 1 before allocating all possible per-cpu areas; then smp_init() expands cpu_possible_map to cpu_present_map (0xf in my case) later on. rc1's commit has good intentions, but expects cpu_present_map to be limited by maxcpus, which is only the case on i386. cpus_and(possible, possible,present) might be good, but needs an audit of cpu_present_map uses - there may well be assumptions that any cpu present is possible. So stay safe for now and just revert those #ifndef CONFIG_HOTPLUG_CPU optimizations in rc1's commit.

If SHUTDOWN-ACK is bundled 300 times in one packet, message will be print 300 times. The same problem also exists when received unexpected HEARTBEAT-ACK message which is bundled message times.

00f1c2d Wei Yongjun 21 August 2007, 07:50:01 UTC SCTP: Fix to encode PROTOCOL VIOLATION error cause correctly PROTOCOL VIOLATION error cause in ABORT is bad encode when make abort chunk. When SCTP encode ABORT chunk with PROTOCOL VIOLATION error cause, it just add the error messages to PROTOCOL VIOLATION error cause, the rest four bytes(struct sctp_paramhdr) is just add to the chunk, not change the length of error cause. This cause the ABORT chunk to be a bad format. The chunk is like this: ABORT chunk Chunk type: ABORT (6) Chunk flags: 0x00 Chunk length: 72 (*1) Protocol violation cause Cause code: Protocol violation (0x000d) Cause length: 62 (*2) Cause information: 5468652063756D756C61746976652074736E2061636B2062...

ada83da Andre Detsch 21 August 2007, 02:06:22 UTC [POWERPC] spufs: Don't call spu_run_init from spu_reacquire_runnable This fixes a major bug which was happening when a SPU thread advances its execution right after being restored to a SPU. A potentially outdated NPC value was being (re)written to the SPU. So, spu_run_init, in this case, was either not doing anything relevant, or breaking the execution of the SPU thread. This fixes a common problem of losing a mailbox write when it was done to a saved context.

aac2e68 Christian Krafft 29 August 2007, 23:33:53 UTC [POWERPC] spu_manage: fix spu_unit_number for celleb device tree This fixes a regression introduced with 2.6.23-rc4 after on some confusion about the device tree interfaces. IBM QS21 device trees provide "physical-id", so we changed the code to run on that and remain compatible with all IBM machines. However, the Toshiba Celleb device tree provides the "unit-id" property, which was in the Linux code, but never used in this way on IBM hardware. Legacy device tree used the reg property for the physical id of an spe. This patch fixes find_spu_unit_number to look for the spu id in that order. The length is checked to avoid misinterpretation in case the attributes unit-id or reg do not contain the id.
