* [PATCH] Call init_timer() for ISDN PPP CCP reset state timerMarcel Holtmann2006-12-22
| | | | | | | | | | | | | The function isdn_ppp_ccp_reset_alloc_state() sets ->timer.function and ->timer.data and later on calls add_timer() with no init_timer() ever done. Noted by Al Viro.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When this code was converted to use sk_for_each() the logic for the "best hash chain length" code was reversed, breaking everything. The original code was of the form: size = 0; do { if (++size >= best_size_so_far) goto next; } while ((sk = sk->next) != NULL); best_size_so_far = size; best = result; next:; and this got converted into: sk_for_each(sk2, node, head) if (++size < best_size_so_far) { best_size_so_far = size; best = result; } Which does something very very different from the original.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | While looking at DCCP sequence numbers, I stumbled over a problem with the following definition of before in tcp.h: static inline int before(__u32 seq1, __u32 seq2) { return (__s32)(seq1-seq2) < 0; } Problem: This definition suffers from an an ambiguity, i.e. always before(a, (a + 2^31) % 2^32)) = 1 before((a + 2^31) % 2^32), a) = 1 In text: when the difference between a and b amounts to 2^31, a is always considered `before' b, the function can not decide. The reason is that implicitly 0 is `before' 1 ... 2^31-1 ... 2^31 Solution: There is a simple fix, by defining before in such a way that 0 is no longer `before' 2^31, i.e. 0 `before' 1 ... 2^31-1 By not using the middle between 0 and 2^32, before can be made unambiguous. This is achieved by testing whether seq2-seq1 > 0 (using signed 32-bit arithmetic). I attach a patch to codify this. Also the `after' relation is basically a redefinition of `before', it is now defined as a macro after before. Signed-off-by: Gerrit Renker <gerrit@erg.abdn.ac.uk> Signed-off-by: David S.

* [PATCH] build compile.h earlierAndrew Morton2006-12-22
| | | | | | | | | | | | | | | | | compile.h is created super-late in the build. But proc_misc.c want to include it, and it's generally not sane to have a header file in include/linux be created at the end of the build: it's either not present or, worse, wrong for most of the build. So the patch arranges for compile.h to be built at the start of the build process. It also consolidates the compile.h rules with those for version.h and utsname.h, so they all get built together. I hope. My chances of having got this right are about 2%. Cc: Sam Ravnborg <sam@ravnborg.org> Signed-off-by: Andrew Morton <akpm@osdl.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org>
* [PATCH] sched: fix bad missed wakeups in the i386, x86_64, ia64, ACPI and ↵Ingo Molnar2006-12-22

The latencies were serious and unjustified by system load, often in the milliseconds range. After a patient and heroic multi-month effort of Fernando, where he tested dozens of kernels, tried various configs, boot options, test-patches of mine and provided latency traces of those incidents, the following 'smoking gun' trace was captured by him: _------=> CPU# / _-----=> irqs-off | / _----=> need-resched || / _---=> hardirq/softirq ||| / _--=> preempt-depth |||| / ||||| delay cmd pid ||||| time | caller \ / ||||| \ | / IRQ_19-1479 1D..1 0us : __trace_start_sched_wakeup (try_to_wake_up) IRQ_19-1479 1D..1 0us : __trace_start_sched_wakeup <<...>-5856> (37 0) IRQ_19-1479 1D..1 0us : __trace_start_sched_wakeup (c01262ba 0 0) IRQ_19-1479 1D..1 0us : resched_task (try_to_wake_up) IRQ_19-1479 1D..1 0us : __spin_unlock_irqrestore (try_to_wake_up) ... <idle>-0 1...1 11us!: default_idle (cpu_idle) ... <idle>-0 0Dn.1 602us : smp_apic_timer_interrupt (c0103baf 1 0) ... <...>-5856 0D..2 618us : __switch_to (__schedule) <...>-5856 0D..2 618us : __schedule <<idle>-0> (20 162) <...>-5856 0D..2 619us : __spin_unlock_irq (__schedule) <...>-5856 0...1 619us : trace_stop_sched_switched (__schedule) <...>-5856 0D..1 619us : trace_stop_sched_switched <<...>-5856> (37 0) what is visible in this trace is that CPU#1 ran try_to_wake_up() for PID:5856, it placed PID:5856 on CPU#0's runqueue and ran resched_task() for CPU#0. But it decided to not send an IPI that no CPU - due to TS_POLLING. But CPU#0 never woke up after its NEED_RESCHED bit was set, and only rescheduled to PID:5856 upon the next lapic timer IRQ. The result was a 600+ usecs latency and a missed wakeup! the bug turned out to be an idle-wakeup bug introduced into the mainline kernel this summer via an optimization in the x86_64 tree: commit 495ab9c045e1b0e5c82951b762257fe1c9d81564 Author: Andi Kleen <ak@suse.de> Date: Mon Jun 26 13:59:11 2006 +0200 [PATCH] i386/x86-64/ia64: Move polling flag into thread_info_status During some profiling I noticed that default_idle causes a lot of memory traffic. I think that is caused by the atomic operations to clear/set the polling flag in thread_info. There is actually no reason to make this atomic - only the idle thread does it to itself, other CPUs only read it. So I moved it into ti->status. the problem is this type of change: if (!hlt_counter && boot_cpu_data.hlt_works_ok) { - clear_thread_flag(TIF_POLLING_NRFLAG); + current_thread_info()->status &= ~TS_POLLING; smp_mb__after_clear_bit(); while (!need_resched()) { local_irq_disable(); this changes clear_thread_flag() to an explicit clearing of TS_POLLING. clear_thread_flag() is defined as: clear_bit(flag, &ti->flags); and clear_bit() is a LOCK-ed atomic instruction on all x86 platforms: static inline void clear_bit(int nr, volatile unsigned long * addr) { __asm__ __volatile__( LOCK_PREFIX "btrl %1,%0" hence smp_mb__after_clear_bit() is defined as a simple compile barrier: #define smp_mb__after_clear_bit() barrier() but the explicit TS_POLLING clearing introduced by the patch: + current_thread_info()->status &= ~TS_POLLING; is not an atomic op! So the clearing of the TS_POLLING bit is freely reorderable with the reading of the NEED_RESCHED bit - and both now reside in different memory addresses. CPU idle wakeup very much depends on ordered memory ops, the clearing of the TS_POLLING flag must always be done before we test need_resched() and hit the idle instruction(s). [Symmetrically, the wakeup code needs to set NEED_RESCHED before it tests the TS_POLLING flag, so memory ordering is paramount.] Fernando's dual-core Athlon64 system has a sufficiently advanced memory ordering model so that it triggered this scenario very often. ( And it also turned out that the reason why these latencies never triggered on my testsystems is that i routinely use idle=poll, which was the only idle variant not affected by this bug. ) The fix is to change the smp_mb__after_clear_bit() to an smp_mb(), to act as an absolute barrier between the TS_POLLING write and the NEED_RESCHED read. This affects almost all idling methods (default, ACPI, APM), on all 3 x86 architectures: i386, x86_64, ia64.

* [PATCH] jbd: wait for already submitted t_sync_datalist buffer to completeHisashi Hifumi2006-12-22
| | | | | | | | | | | | | | | | | | | | | In the current jbd code, if a buffer on BJ_SyncData list is dirty and not locked, the buffer is refiled to BJ_Locked list, submitted to the IO and waited for IO completion. But the fsstress test showed the case that when a buffer was already submitted to the IO just before the buffer_dirty(bh) check, the buffer was not waited for IO completion. Following patch solves this problem. If it is assumed that a buffer is submitted to the IO before the buffer_dirty(bh) check and still being written to disk, this buffer is refiled to BJ_Locked list.

* [PATCH] increase CARDBUS_MEM_SIZEAndrew Morton2006-12-22
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Linus sayeth: Google knows everything, and finds, on MS own site no less: "Windows 2000 default resources: One 4K memory window One 2 MB memory window Two 256-byte I/O windows" which is clearly utterly bogus and insufficient. But Microsoft apparently realized this, and: "Windows XP default resources: Because one memory window of 4K and one window of 2 MB are not sufficient for CardBus controllers in many configurations, Windows XP allocates larger memory windows to CardBus controllers where possible. However, resource windows are static (that is, the operating system does not dynamically allocate larger memory windows if new devices appear.) Under Windows XP, CardBus controllers will be assigned the following resources: One 4K memory window, as in Windows 2000 64 MB memory, if that amount of memory is available. If 64 MB is not available the controller will receive 32 MB; if 32 MB is not available, the controller will receive 16 MB; if 16 MB is not available, the bridge will receive 8 MB; and so on down to a minimum assignment of 1 MB in configurations where memory is too constrained for the operating system to provide a larger window. Two 256-byte I/O windows" So I think we have our answer. Windows uses one 4k window, and one 64MB window. And they are no more dynamic than we are (we _could_ try to do it dynamically, but let's face it, it's fairly painful to dynamically expand PCI bus resources - you may need to reprogram everything up to the root, so it would be absolutely crazy to do that unless you have some serious masochistic tendencies). So let's just increase our default value to 64M too.

* [PATCH] ptrace: Fix EFL_OFFSET value according to i386 pda changesJeremy Fitzhardinge2006-12-22
| | | | | | | | | | | | | | | | | | | The PDA patches introduced a bug in ptrace: it reads eflags from the wrong place on the target's stack, but writes it back to the correct place. The result is a corrupted eflags, which is most visible when it turns interrupts off unexpectedly. This patch fixes this by making the ptrace code a little less fragile. It changes [gs]et_stack_long to take a straightforward byte offset into struct pt_regs, rather than requiring all callers to do a sizeof(struct pt_regs) offset adjustment. This means that the eflag's offset (EFL_OFFSET) on the target stack can be simply computed with offsetof().

* [PATCH] compile error of register_memory()Yasunori Goto2006-12-22
| | | | | | | | | | | | | register_memory() becomes double definition in 2.6.20-rc1. It is defined in arch/i386/kernel/setup.c as static definition in 2.6.19. But it is moved to arch/i386/kernel/e820.c in 2.6.20-rc1. And same name function is defined in driver/base/memory.c too. So, it becomes cause of compile error of duplicate definition if memory hotplug option is on.

| | | | | | | | | | | | | | | | | | | | Fix a bug that only appears when AoE goes over a network card that does not support scatter-gather. The headers in the linear part of the skb appeared to be larger than they really were, resulting in data that was offset by 24 bytes. This patch eliminates the offset data on cards that don't support scatter-gather or have had scatter-gather turned off. There remains an unrelated issue that I'll address in a separate email.

* [PATCH] fsstack: Remove inode copyMichael Halcrow2006-12-22

This was the eCryptfs copy_attr_all: > -void ecryptfs_copy_attr_all(struct inode *dest, const struct inode *src) > -{ > - dest->i_mode = src->i_mode; > - dest->i_nlink = src->i_nlink; > - dest->i_uid = src->i_uid; > - dest->i_gid = src->i_gid; > - dest->i_rdev = src->i_rdev; > - dest->i_atime = src->i_atime; > - dest->i_mtime = src->i_mtime; > - dest->i_ctime = src->i_ctime; > - dest->i_blkbits = src->i_blkbits; > - dest->i_flags = src->i_flags; > -} This is the fsstack copy_attr_all: > +void fsstack_copy_attr_all(struct inode *dest, const struct inode *src, > + int (*get_nlinks)(struct inode *)) > +{ > + if (!get_nlinks) > + dest->i_nlink = src->i_nlink; > + else > + dest->i_nlink = (*get_nlinks)(dest); > + > + dest->i_mode = src->i_mode; > + dest->i_uid = src->i_uid; > + dest->i_gid = src->i_gid; > + dest->i_rdev = src->i_rdev; > + dest->i_atime = src->i_atime; > + dest->i_mtime = src->i_mtime; > + dest->i_ctime = src->i_ctime; > + dest->i_blkbits = src->i_blkbits; > + dest->i_flags = src->i_flags; > + > + fsstack_copy_inode_size(dest, src); > +} The addition of copy_inode_size breaks eCryptfs, since eCryptfs needs to interpolate the file sizes (eCryptfs has extra space in the lower file for the header). The setting of the upper inode size occurs elsewhere in eCryptfs, and the new copy_attr_all now undoes what eCryptfs was doing right beforehand. I see three ways of going forward from here. (1) Something like this patch needs to go in (assuming it jives with Unionfs), (2) we need to make a change to the fsstack API for more fine-grained control over copying attributes (e.g., by also including a callback function for calculating the right file size, which will require some more work on both eCryptfs and Unionfs), or (3) the fsstack patch on eCryptfs (commit 0cc72dc7f050188d8d7344b1dd688cbc68d3cd30 made on Fri Dec 8 02:36:31 2006 -0800) needs to be yanked in 2.6.20. I think the simplest solution, from eCryptfs' perspective, is to just remove the inode size copy. Remove inode size copy in general fsstack attr copy code. Stacked filesystems may need to interpolate the inode size, since the file size in the lower file may be different than the file size in the stacked layer.
