13e12d1 Linus Torvalds 08 June 2011, 22:18:19 UTC vfs: reorganize 'struct inode' layout a bit This tries to make the 'struct inode' accesses denser in the data cache by moving a commonly accessed field (i_security) closer to other fields that are accessed often. It also makes 'i_state' just an 'unsigned int' rather than 'unsigned long', since we only use a few bits of that field, and moves it next to the existing 'i_flags' so that we potentially get better structure layout (although depending on config options, i_flags may already have packed in the same word as i_lock, so this improves packing only for the case of spinlock debugging) Out 'struct inode' is still way too big, and we should probably move some other fields around too (the acl fields in particular) for better data cache access density. Other fields (like the inode hash) are likely to be entirely irrelevant under most loads. Signed-off-by: Linus Torvalds <torvalds@linux-foundation.org> 08 June 2011, 22:18:19 UTC
95f4efb Linus Torvalds 08 June 2011, 22:11:56 UTC selinux: simplify and clean up inode_has_perm() This is a rather hot function that is called with a potentially NULL "struct common_audit_data" pointer argument. And in that case it has to provide and initialize its own dummy common_audit_data structure. However, all the _common_ cases already pass it a real audit-data structure, so that uncommon NULL case not only creates a silly run-time test, more importantly it causes that function to have a big stack frame for the dummy variable that isn't even used in the common case! So get rid of that stupid run-time behavior, and make the (few) functions that currently call with a NULL pointer just call a new helper function instead (naturally called inode_has_perm_noapd(), since it has no adp argument). This makes the run-time test be a static code generation issue instead, and allows for a much denser stack since none of the common callers need the dummy structure. And a denser stack not only means less stack space usage, it means better cache behavior. So we have a win-win-win from this simplification: less code executed, smaller stack footprint, and better cache behavior.

723bda2 Josef Bacik 27 May 2011, 20:11:38 UTC Btrfs: fix the allocator loop logic I was testing with empty_cluster = 0 to try and reproduce a problem and kept hitting early enospc panics. This was because our loop logic was a little confused. So this is what I did 1) Make the loop variable the ultimate decider on wether we should loop again isntead of checking to see if we had an uncached bg, empty size or empty cluster. 2) Increment loop before checking to see what we are on to make the loop definitions make more sense. 3) If we are on the chunk alloc loop don't set empty_size/empty_cluster to 0 unless we didn't actually allocate a chunk. If we did allocate a chunk we should be able to easily setup a new cluster so clearing empty_size/empty_cluster makes us less efficient. This kept me from hitting panics while trying to reproduce the other problem. Thanks, Signed-off-by: Josef Bacik <josef@redhat.com> 08 June 2011, 20:37:29 UTC
2cdc342 Josef Bacik 27 May 2011, 18:07:49 UTC Btrfs: fix bitmap regression In cleaning up the clustering code I accidently introduced a regression by adding bitmap entries to the cluster rb tree. The problem is if we've maxed out the number of bitmaps we can have for the block group we can only add free space to the bitmaps, but since the bitmap is on the cluster we can't find it and we try to create another one. This would result in a panic because the total bitmaps was bigger than the max bitmaps that were allowed. This patch fixes this by checking to see if we have a cluster, and then looking at the cluster rb tree to see if it has a bitmap entry and if it does and that space belongs to that bitmap, go ahead and add it to that bitmap. I could hit this panic every time with an fs_mark test within a couple of minutes. With this patch I no longer hit the panic and fs_mark goes to completion.

So instead add the bitmap entries to a temporary list so if we have to do the bitmap search we can just look through the list of entries we've found quickly instead of having to loop through the entire tree again.

f3209be Johannes Berg 08 June 2011, 11:27:29 UTC mac80211: fix IBSS teardown race Ignacy reports that sometimes after leaving an IBSS joining a new one didn't work because there still were stations on the list. He fixed it by flushing stations when attempting to join a new IBSS, but this shouldn't be happening in the first case. When I looked into it I saw a race condition in teardown that could cause stations to be added after flush, and thus cause this situation. Ignacy confirms that after applying my patch he hasn't seen this happen again.

81de916 Linus Torvalds 08 June 2011, 14:46:30 UTC tty_buffer: get rid of 'seen_tail' logic in flush_to_ldisc The flush_to_ldisc() work entry has special logic to notice when it has seen the original tail of the data queue, and it avoids continuing the flush if it sees that _original_ tail rather than the current tail. This logic can trigger in case somebody is constantly adding new data to the tty while the flushing is active - and the intent is to avoid excessive CPU usage while flushing the tty, especially as we used to do this from a softirq context which made it non-preemptible. However, since we no longer re-arm the work-queue from within itself (because that causes other trouble: see commit a5660b41af6a "tty: fix endless work loop when the buffer fills up"), this just leads to possible hung tty's (most easily seen in SMP and with a test-program that floods a pty with data - nobody seems to have reported this for any real-life situation yet). And since the workqueue isn't done from timers and softirq's any more, it's doubtful whether the CPU useage issue is really relevant any more. So just remove the logic entirely, and see if anybody ever notices. Alternatively, we might want to re-introduce the "re-arm the work" for just this case, but then we'd have to re-introduce the delayed work model or some explicit timer, which really doesn't seem worth it for this.

fd8a7de Thomas Gleixner 20 July 2010, 12:34:50 UTC x86: cpu-hotplug: Prevent softirq wakeup on wrong CPU After a newly plugged CPU sets the cpu_online bit it enables interrupts and goes idle. The cpu which brought up the new cpu waits for the cpu_online bit and when it observes it, it sets the cpu_active bit for this cpu. The cpu_active bit is the relevant one for the scheduler to consider the cpu as a viable target. With forced threaded interrupt handlers which imply forced threaded softirqs we observed the following race: cpu 0 cpu 1 bringup(cpu1); set_cpu_online(smp_processor_id(), true); local_irq_enable(); while (!cpu_online(cpu1)); timer_interrupt() -> wake_up(softirq_thread_cpu1); -> enqueue_on(softirq_thread_cpu1, cpu0); ^^^^ cpu_notify(CPU_ONLINE, cpu1); -> sched_cpu_active(cpu1) -> set_cpu_active((cpu1, true); When an interrupt happens before the cpu_active bit is set by the cpu which brought up the newly onlined cpu, then the scheduler refuses to enqueue the woken thread which is bound to that newly onlined cpu on that newly onlined cpu due to the not yet set cpu_active bit and selects a fallback runqueue. Not really an expected and desirable behaviour. So far this has only been observed with forced hard/softirq threading, but in theory this could happen without forced threaded hard/softirqs as well. It's probably unobservable as it would take a massive interrupt storm on the newly onlined cpu which causes the softirq loop to wake up the softirq thread and an even longer delay of the cpu which waits for the cpu_online bit.

Instead it should use probe_kernel_read(). This fixes the problem of gdb seeing SIGILL rather than SIGTRAP when hitting the KGDB special breakpoint upon SysRq+g being seen. The problem was that die_if_no_fixup() was failing to read the opcode of the instruction that caused the exception, and thus not fixing up the exception. This caused gdb to get a S04 response to the $? request in its remote protocol rather than S05 - which would then cause it to continue with $C04 rather than $c in an attempt to pass the signal onto the inferior process. The kernel, however, does not support $Cnn, and so objects by returning an E22 response, indicating an error. gdb does not expect this and prints: warning: Remote failure reply: E22 and then returns to the gdb command prompt unable to continue.

ea16058 oftedal 01 June 2011, 11:04:20 UTC Do not skip interrupt sources in sun4d interrupt handler and acknowledge interrupts correctly During the introduction of genirq on sparc32 bugs were introduced in the interrupt handler for sun4d. The interrupts handler checks the status of the various sbus interfaces in the system and generates a virtual interrupt, based upon the location of the interrupt source. This lookup was broken by restructuring the code in such a way that index and shift operations were performed prior to comparing this against the values read from the interrupt controllers. This could cause the handler to loop eternally as the interrupt source could be skipped before any check was performed. Additionally sun4d_encode_irq performs shifting internally, so it should not be performed twice. In sun4d_unmask interrupts were not correctly acknowledged, as the corresponding bit it the interrupt mask was not actually cleared.

This caused a NULL pointer crash. Josip Rodin suggested that the current sun4d_build_device_irq should be split into two functions. So that the timer initialization could skip the slot and sbus interface detection code in sun4d_build_device_irq, as this does not make sence due to the timer interrupts not being generated from a device located on sbus.

8c56cac Tejun Heo 25 May 2011, 11:19:39 UTC libata: fix unexpectedly frozen port after ata_eh_reset() To work around controllers which can't properly plug events while reset, ata_eh_reset() clears error states and ATA_PFLAG_EH_PENDING after reset but before RESET is marked done. As reset is the final recovery action and full verification of devices including onlineness and classfication match is done afterwards, this shouldn't lead to lost devices or missed hotplug events. Unfortunately, it forgot to thaw the port when clearing EH_PENDING, so if the condition happens after resetting an empty port, the port could be left frozen and EH will end without thawing it, making the port unresponsive to further hotplug events. Thaw if the port is frozen after clearing EH_PENDING. This problem is reported by Bruce Stenning in the following thread. http://thread.gmane.org/gmane.linux.kernel/1123265 stable: I think we should weather this patch a bit longer in -rcX before sending it to -stable.

aaa5c67 Michael Chang 30 May 2011, 06:28:25 UTC staging: gma500: get control from firmware framebuffer if conflicts Many Linux distributions would enable vesafb in order to display early stage boot splash. In this case, we will get garbled X Window screen if running X fbdev on psbfb. This is because fb0 is occupied by vesafb while psbfb is on fb1. They tried to drive the same pieces of hardware at the same time. With unmodified X start-up, it would try to use default fb0 framebuffer device and unfortunately it is now broken becaues fb1 supersedes it. We should let psbfb takeover framebuffer control from vesafb to get around this problem.

21c13a4 Alan Stern 07 June 2011, 15:35:52 UTC usb-storage: redo incorrect reads Some USB mass-storage devices have bugs that cause them not to handle the first READ(10) command they receive correctly. The Corsair Padlock v2 returns completely bogus data for its first read (possibly it returns the data in encrypted form even though the device is supposed to be unlocked). The Feiya SD/SDHC card reader fails to complete the first READ(10) command after it is plugged in or after a new card is inserted, returning a status code that indicates it thinks the command was invalid, which prevents the kernel from retrying the read. Since the first read of a new device or a new medium is for the partition sector, the kernel is unable to retrieve the device's partition table. Users have to manually issue an "hdparm -z" or "blockdev --rereadpt" command before they can access the device. This patch (as1470) works around the problem. It adds a new quirk flag, US_FL_INVALID_READ10, indicating that the first READ(10) should always be retried immediately, as should any failing READ(10) commands (provided the preceding READ(10) command succeeded, to avoid getting stuck in a loop). The patch also adds appropriate unusual_devs entries containing the new flag.

264524d Heiko Carstens 06 June 2011, 20:50:03 UTC net: cpu offline cause napi stall Frank Blaschka reported : <quote> During heavy network load we turn off/on cpus. Sometimes this causes a stall on the network device. Digging into the dump I found out following: napi is scheduled but does not run. From the I/O buffers and the napi state I see napi/rx_softirq processing has stopped because the budget was reached. napi stays in the softnet_data poll_list and the rx_softirq was raised again. I assume at this time the cpu offline comes in, the rx softirq is raised/moved to another cpu but napi stays in the poll_list of the softnet_data of the now offline cpu. Reviewing dev_cpu_callback (net/core/dev.c) I did not find the poll_list is transfered to the new cpu. </quote> This patch is a straightforward implementation of Frank suggestion : Transfert poll_list and trigger NET_RX_SOFTIRQ on new cpu.

6407d74 Alexander Holler 07 June 2011, 07:51:35 UTC bridge: provide a cow_metrics method for fake_ops Like in commit 0972ddb237 (provide cow_metrics() methods to blackhole dst_ops), we must provide a cow_metrics for bridges fake_dst_ops as well. This fixes a regression coming from commits 62fa8a846d7d (net: Implement read-only protection and COW'ing of metrics.) and 33eb9873a28 (bridge: initialize fake_rtable metrics) ip link set mybridge mtu 1234 --> [ 136.546243] Pid: 8415, comm: ip Tainted: P 2.6.39.1-00006-g40545b7 #103 ASUSTeK Computer Inc.
