19242b2 Arnd Bergmann 15 June 2006, 11:15:44 UTC [PATCH] powerpc: Fix 64k pages on non-partitioned machines The page size encoding passed to tlbie is incorrect for new-style large pages. This fixes it. This doesn't affect anything on older machines because mmu_psize_defs[psize].penc (the page size encoding) is 0 for 4k and 16M pages (the two are distinguished by a separate "is a large page" bit).

f53ae1d Oleg Nesterov 15 June 2006, 16:12:02 UTC [PATCH] arm_timer: remove a racy and obsolete PF_EXITING check arm_timer() checks PF_EXITING to prevent BUG_ON(->exit_state) in run_posix_cpu_timers(). However, for some reason it does so only for CPUCLOCK_PERTHREAD case (which is imho wrong). Also, this check is not reliable, PF_EXITING could be set on another cpu without any locks/barriers just after the check, so it can't prevent from attaching the timer to the exiting task. The previous patch makes this check unneeded. Signed-off-by: Oleg Nesterov <oleg@tv-sign.ru> Signed-off-by: Linus Torvalds <torvalds@osdl.org> 17 June 2006, 17:52:13 UTC
30f1e3d Oleg Nesterov 15 June 2006, 16:11:43 UTC [PATCH] run_posix_cpu_timers: remove a bogus BUG_ON() do_exit() clears ->it_##clock##_expires, but nothing prevents another cpu to attach the timer to exiting process after that. arm_timer() tries to protect against this race, but the check is racy. After exit_notify() does 'write_unlock_irq(&tasklist_lock)' and before do_exit() calls 'schedule() local timer interrupt can find tsk->exit_state != 0. If that state was EXIT_DEAD (or another cpu does sys_wait4) interrupted task has ->signal == NULL. At this moment exiting task has no pending cpu timers, they were cleanuped in __exit_signal()->posix_cpu_timers_exit{,_group}(), so we can just return from irq.

8f17fc2 Oleg Nesterov 15 June 2006, 16:11:15 UTC [PATCH] check_process_timers: fix possible lockup If the local timer interrupt happens just after do_exit() sets PF_EXITING (and before it clears ->it_xxx_expires) run_posix_cpu_timers() will call check_process_timers() with tasklist_lock + ->siglock held and check_process_timers: t = tsk; do { .... do { t = next_thread(t); } while (unlikely(t->flags & PF_EXITING)); } while (t != tsk); the outer loop will never stop. Actually, the window is bigger. Another process can attach the timer after ->it_xxx_expires was cleared (see the next commit) and the 'if (PF_EXITING)' check in arm_timer() is racy (see the one after that).

88d1136 Stephen Hemminger 16 June 2006, 19:10:46 UTC [PATCH] sky2: netconsole suspend/resume interaction A couple of fixes that should prevent crashes when using netconsole and suspend/resume. First, netconsole poll routine shouldn't run unless the device is up; second, the NAPI poll should be disabled during suspend. This is only an issue on sky2, because it has to have one NAPI poll routine for both ports on dual port boards. Normal drivers use netif_rx_schedule_prep and that checks for netif_running.

1607042 Jens Axboe 16 June 2006, 05:46:37 UTC [PATCH] fix cdrom open Some time ago the cdrom open routine was changed so that we call the driver's open routine before checking to see if it is read only. However, if we discovered that a read write open was not possible and the open flags required a writable open, we just returned -EROFS without calling the driver's release routine. This seems to work for most cdrom drivers, but breaks the Powerpc iSeries virtual cdrom rather badly. This just inserts the release call in the error path to balance the call to "->open()" done by "open_for_data()".

cfd95a9 Robin H. Johnson 12 June 2006, 20:50:25 UTC [PATCH] tmpfs: time granularity fix for [acm]time going backwards I noticed a strange behavior in a tmpfs file system the other day, while building packages - occasionally, and seemingly at random, make decided to rebuild a target. However, only on tmpfs. A file would be created, and if checked, it had a sub-second timestamp. However, after an utimes related call where sub-seconds should be set, they were zeroed instead. In the case that a file was created, and utimes(...,NULL) was used on it in the same second, the timestamp on the file moved backwards. After some digging, I found that this was being caused by tmpfs not having a time granularity set, thus inheriting the default 1 second granularity. Hugh adds: yes, we missed tmpfs when the s_time_gran mods went into 2.6.11. Unfortunately, the granularity of CURRENT_TIME, often used in filesystems, does not match the default granularity set by alloc_super. A few more such discrepancies have been found, but this is the most important to fix now. Signed-off-by: Robin H.

79320d7 Aki M Nyrhinen 12 June 2006, 04:18:56 UTC [TCP]: continued: reno sacked_out count fix From: Aki M Nyrhinen <anyrhine@cs.helsinki.fi> IMHO the current fix to the problem (in_flight underflow in reno) is incorrect. it treats the symptons but ignores the problem. the problem is timing out packets other than the head packet when we don't have sack. i try to explain (sorry if explaining the obvious). with sack, scanning the retransmit queue for timed out packets is fine because we know which packets in our retransmit queue have been acked by the receiver. without sack, we know only how many packets in our retransmit queue the receiver has acknowledged, but no idea which packets. think of a "typical" slow-start overshoot case, where for example every third packet in a window get lost because a router buffer gets full. with sack, we check for timeouts on those every third packet (as the rest have been sacked). the packet counting works out and if there is no reordering, we'll retransmit exactly the packets that were lost. without sack, however, we check for timeout on every packet and end up retransmitting consecutive packets in the retransmit queue. in our slow-start example, 2/3 of those retransmissions are unnecessary. these unnecessary retransmissions eat the congestion window and evetually prevent fast recovery from continuing, if enough packets were lost.

289a1e9 Paul Mackerras 12 June 2006, 02:16:26 UTC [PATCH] Fix for the PPTP hangs that have been reported People have been reporting that PPP connections over ptys, such as used with PPTP, will hang randomly when transferring large amounts of data, for instance in http://bugzilla.kernel.org/show_bug.cgi?id=6530. I have managed to reproduce the problem, and the patch below fixes the actual cause. The problem is not in fact in ppp_async.c but in n_tty.c. What happens is that when pptp reads from the pty, we call read_chan() in drivers/char/n_tty.c on the master side of the pty. That copies all the characters out of its buffer to userspace and then calls check_unthrottle(), which calls the pty unthrottle routine, which calls tty_wakeup on the slave side, which calls ppp_asynctty_wakeup, which calls tasklet_schedule. So far so good. Since we are in process context, the tasklet runs immediately and calls ppp_async_process(), which calls ppp_async_push, which calls the tty->driver->write function to send some more output. However, tty->driver->write() returns zero, because the master tty->receive_room is still zero. We haven't returned from check_unthrottle() yet, and read_chan() only updates tty->receive_room _after_ calling check_unthrottle. That means that the driver->write call in ppp_async_process() returns 0. That would be fine if we were going to get a subsequent wakeup call, but we aren't (we just had it, and the buffer is now empty). The solution is for n_tty.c to update tty->receive_room _before_ calling the driver unthrottle routine. The patch below does this. With this patch I was able to transfer a 900MB file over a PPTP connection (taking about 25 minutes), whereas without the patch the connection would always stall in under a minute.

670bd95 David Howells 10 June 2006, 16:54:12 UTC [PATCH] Further alterations for memory barrier document From: David Howells <dhowells@redhat.com> Apply some alterations to the memory barrier document that I worked out with Paul McKenney of IBM, plus some of the alterations suggested by Alan Stern. The following changes were made: (*) One of the examples given for what can happen with overlapping memory barriers was wrong. (*) The description of general memory barriers said that a general barrier is a combination of a read barrier and a write barrier. This isn't entirely true: it implies both, but is more than a combination of both. (*) The first example in the "SMP Barrier Pairing" section was wrong: the loads around the read barrier need to touch the memory locations in the opposite order to the stores around the write barrier. (*) Added a note to make explicit that the loads should be in reverse order to the stores. (*) Adjusted the diagrams in the "Examples Of Memory Barrier Sequences" section to make them clearer. Added a couple of diagrams to make it more clear as to how it could go wrong without the barrier. (*) Added a section on memory speculation. (*) Dropped any references to memory allocation routines doing memory barriers. They may do sometimes, but it can't be relied on. This may be worthy of further documentation later. (*) Made the fact that a LOCK followed by an UNLOCK should not be considered a full memory barrier more explicit and gave an example.

bc1c116 Jens Axboe 08 June 2006, 06:49:06 UTC [PATCH] elevator switching race There's a race between shutting down one io scheduler and firing up the next, in which a new io could enter and cause the io scheduler to be invoked with bad or NULL data. To fix this, we need to maintain the queue lock for a bit longer. Unfortunately we cannot do that, since the elevator init requires to be run without the lock held. This isn't easily fixable, without also changing the mempool API. So split the initialization into two parts, and alloc-init operation and an attach operation. Then we can preallocate the io scheduler and related structures, and run the attach inside the lock after we detach the old one. This patch has survived 30 minutes of 1 second io scheduler switching with a very busy io load.

e2f04e1 Matt Reimer 08 June 2006, 21:46:48 UTC [ARM] 3546/1: PATCH: subtle lost interrupts bug on i.MX Patch from Matt Reimer There is a subtle bug in the GPIO interrupt status register handling in arch/arm/mach-imx/irq.c:imx_gpio_ack_irq(). The documentation states that a 1 should be written to the relevant bit to acknowledge a GPIO interrupt, but that is not what the code does. The problem is that the |= writes back 1s for all the *other* interrupts represented in the register, so interrupts could get lost. For example, if interrupts are pending for GPIO B10 and B12, ISR_B would have the value 0x00001400. Then when the interrupt code handles GPIO B10, it eventually calls imx_gpio_ack_irq(IRQ_GPIOB(10)), which effectively does this: ISR_B |= 1 << 10; with the result that (0x00001400 | 0x00000400) is written, clearing the interrupt status bits for *both* GPIO B10 and B12. The fix is to write 1s only for the interrupts we want to clear. The same problem seems to be occurring in the DMA code; this patch does not address those issues.

So, switch to storing the swap entry in 'pte_high' field using all its bits except _PAGE_GLOBAL and _PAGE_VALID which gives 25 bits for the swap entry offset.

f291196 Herbert Xu ~{PmVHI~} 05 June 2006, 22:03:37 UTC [TCP]: Avoid skb_pull if possible when trimming head Trimming the head of an skb by calling skb_pull can cause the packet to become unaligned if the length pulled is odd. Since the length is entirely arbitrary for a FIN packet carrying data, this is actually quite common. Unaligned data is not the end of the world, but we should avoid it if it's easily done. In this case it is trivial. Since we're discarding all of the head data it doesn't matter whether we move skb->data forward or back. However, it is still possible to have unaligned skb->data in general. So network drivers should be prepared to handle it instead of crashing. This patch also adds an unlikely marking on len < headlen since partial ACKs on head data are extremely rare in the wild. As the return value of __pskb_trim_head is no longer ever NULL that has been removed. Signed-off-by: Herbert Xu ~{PmV>HI~} <herbert@gondor.apana.org.au> Signed-off-by: David S.
