I added a WARN_ON to get automated information via kerneloops.org and to get some direct reports, which allowed me to analyse the affected machines. The WARN_ON has served its purpose and would be annoying for a release kernel. Remove it and just keep the information about the increase of the min_delta_ns value.

It is the initiators job to create a secure ACL link. However in case of malicious devices, the acceptor has to make sure that the ACL is encrypted before allowing any kind of L2CAP connection. The only exception here is the PSM 1 for the service discovery protocol, because that is allowed to run on an insecure ACL link. Previously it was enough to reject a L2CAP connection during the connection setup phase, but with Bluetooth 2.1 it is forbidden to do any L2CAP protocol exchange on an insecure link (except SDP). The new hci_conn_check_link_mode() function can be used to check the integrity of an ACL link. This functions also takes care of the cases where Security Mode 4 is disabled or one of the devices is based on an older specification. Signed-off-by: Marcel Holtmann commit 09ab6f4c2376a0fc31abde1e2991513f900ea825 Author: Marcel Holtmann Date: Tue Sep 9 07:19:20 2008 +0200 [Bluetooth] Enforce correct authentication requirements With the introduction of Security Mode 4 and Simple Pairing from the Bluetooth 2.1 specification it became mandatory that the initiator requires authentication and encryption before any L2CAP channel can be established. The only exception here is PSM 1 for the service discovery protocol (SDP). It is meant to be used without any encryption since it contains only public information. This is how Bluetooth 2.0 and before handle connections on PSM 1. For Bluetooth 2.1 devices the pairing procedure differentiates between no bonding, general bonding and dedicated bonding. The L2CAP layer wrongly uses always general bonding when creating new connections, but it should not do this for SDP connections. In this case the authentication requirement should be no bonding and the just-works model should be used, but in case of non-SDP connection it is required to use general bonding. If the new connection requires man-in-the-middle (MITM) protection, it also first wrongly creates an unauthenticated link key and then later on requests an upgrade to an authenticated link key to provide full MITM protection. With Simple Pairing the link key generation is an expensive operation (compared to Bluetooth 2.0 and before) and doing this twice during a connection setup causes a noticeable delay when establishing a new connection. This should be avoided to not regress from the expected Bluetooth 2.0 connection times. The authentication requirements are known up-front and so enforce them. To fulfill these requirements the hci_connect() function has been extended with an authentication requirement parameter that will be stored inside the connection information and can be retrieved by userspace at any time. This allows the correct IO capabilities exchange and results in the expected behavior.

This results in keeping an ACL link up without any users. The problem here is that the Bluetooth specification doesn't define an ownership of the ACL link and thus it can happen that the implementation on the initiator side doesn't care about disconnecting unused links. In this case the acceptor needs to take care of this. Signed-off-by: Marcel Holtmann commit 2eb2f77900d62796934bcd43c4089e444cf1179e Author: David S.

The Linux automounter uses the mount command's "-s" command line option ("s" for "sloppy") so that mount requests containing such options are not rejected. Commit f45663ce5fb30f76a3414ab3ac69f4dd320e760a attempted to address a known regression with text-based NFS mount option parsing. Unrecognized mount options would cause mount requests to fail, even if the "-s" option was used on the mount command line. Unfortunately, this commit was not complete as submitted. It adds a new mount option, "sloppy". But it is missing a hunk, so it now allows NFS mounts with unrecognized mount options, even if the "sloppy" option is not present. This could be a problem if a required critical mount option such as "sync" is misspelled, for example, and is considered a regression from 2.6.26. This patch restores the missing hunk. Now, the default behavior of text-based NFS mount options is as before: any unrecognized mount option will cause the mount to fail. Please include this in 2.6.27-rc.

He then correlated this with a report by bdupree@techfinesse.com: http://marc.info/?l=linux-kernel&m=119613299024398&w=2 and the culprit cause seems to be starting the bridge interface. In particular, when starting the bridge interface, his scripts are specifying a hello timer interval of "0". The bridge hello time can't be safely set to values less than 1 second, otherwise it is possible to end up with a runaway timer. Signed-off-by: Stephen Hemminger Signed-off-by: David S.

The timewait sockets life cycle is not tied with the network namespace, that means the timewait sockets stay alive while the network namespace dies. The timewait sockets are for avoiding to receive a duplicate packet from the network, if the network namespace is freed, the network stack is removed, so no chance to receive any packets from the outside world. Furthermore, having a pending destruction timer on these sockets with a network namespace freed is not safe and will lead to an oops if the timer callback which try to access data belonging to the namespace like for example in: inet_twdr_do_twkill_work -> NET_INC_STATS_BH(twsk_net(tw), LINUX_MIB_TIMEWAITED); Purging the timewait sockets at the network namespace destruction will: 1) speed up memory freeing for the namespace 2) fix kernel panic on asynchronous timewait destruction Signed-off-by: Daniel Lezcano Acked-by: Denis V.

So I would suggest perhaps moving the static P6 nop selection into the CONFIG_X86_64 thing. The alternative is to just get rid of that static nop selection, and just have two cases: 32-bit and 64-bit, and just pick obviously safe cases for them. Signed-off-by: H.

Jeff added the Marvell device identifiers to the ahci driver without making the AHCI driver handle the PATA port. This means a lot of users can't use current kernels and in most distro cases can't even install. This has been going on since March 2008 for the 6121 Marvell, and late 2007 for the 6145!!! This was all pointed out at the time and repeatedly ignored. Bugs assigned to Jeff about this are ignored also. To quote Jeff in email > "Just switch the order of 'ahci' and 'pata_marvell' in > /etc/modprobe.conf, then use Fedora's tools regenerate the initrd. > See? It's not rocket science, and the current configuration can be > easily made to work for Fedora users." (Which isn't trivial, isn't end user, shouldn't be needed, and as it usually breaks at install time is in fact impossible) To quote Jeff in August 2007 > " mv-ahci-pata > Marvell 6121/6141 PATA support. Needs fixing in the 'PATA controller > command' area before it is usable, and can go upstream." Only he add the ids anyway later and caused regressions, adding a further id in March causing more regresions. The actual fix for the moment is very simple. If the user has included the pata_marvell driver let it drive the ports. If they've only selected for SATA support give them the AHCI driver which will run the port a fraction faster. Allow the user to control this decision via ahci.marvell_enable as a module parameter so that distributions can ship 'it works' defaults and smarter users (or config tools) can then flip it over it desired.

To fix this issue, expand the check for monotonicity by doing ten consecutive tests instead of one.

On those chipsets, we need to read out the timer value at least three times to get a correct result, for every once in a while (i.e. within a 3 ns window every 69.8 ns) the read returns a bogus result. During normal operation we work around this issue, but during initialization reading a bogus value may lead to -EINVAL even though the hardware is usable. Thanks to Andreas Mohr for spotting this issue.

Rozycki Date: Fri Sep 5 14:05:31 2008 -0700 ntp: fix calculation of the next jiffie to trigger RTC sync We have a bug in the calculation of the next jiffie to trigger the RTC synchronisation. The aim here is to run sync_cmos_clock() as close as possible to the middle of a second. Which means we want this function to be called less than or equal to half a jiffie away from when now.tv_nsec equals 5e8 (500000000). If this is not the case for a given call to the function, for this purpose instead of updating the RTC we calculate the offset in nanoseconds to the next point in time where now.tv_nsec will be equal 5e8. The calculated offset is then converted to jiffies as these are the unit used by the timer. Hovewer timespec_to_jiffies() used here uses a ceil()-type rounding mode, where the resulting value is rounded up. As a result the range of now.tv_nsec when the timer will trigger is from 5e8 to 5e8 + TICK_NSEC rather than the desired 5e8 - TICK_NSEC / 2 to 5e8 + TICK_NSEC / 2. As a result if for example sync_cmos_clock() happens to be called at the time when now.tv_nsec is between 5e8 + TICK_NSEC / 2 and 5e8 to 5e8 + TICK_NSEC, it will simply be rescheduled HZ jiffies later, falling in the same range of now.tv_nsec again. Similarly for cases offsetted by an integer multiple of TICK_NSEC. This change addresses the problem by subtracting TICK_NSEC / 2 from the nanosecond offset to the next point in time where now.tv_nsec will be equal 5e8, effectively shifting the following rounding in timespec_to_jiffies() so that it produces a rounded-to-nearest result.

We use different page table attributes depending on which CPU we are running on: - Non-XScale ARMv5 and earlier systems: The ARMv5 ARM documents four possible mapping types (CB=00/01/10/11). We can't use any of the cached memory types (CB=10/11), since that breaks coherency with peripheral devices. Both CB=00 and CB=01 are suitable for _wc, and CB=01 (Uncached/Buffered) allows the hardware more freedom than CB=00, so we'll use that. (The ARMv5 ARM seems to suggest that CB=01 is allowed to delay stores but isn't allowed to merge them, but there is no other mapping type we can use that allows the hardware to delay and merge stores, so we'll go with CB=01.) - XScale v1/v2 (ARMv5): same as the ARMv5 case above, with the slight difference that on these platforms, CB=01 actually _does_ allow merging stores. (If you want noncoalescing bufferable behavior on Xscale v1/v2, you need to use XCB=101.) - Xscale v3 (ARMv5) and ARMv6+: on these systems, we use TEXCB=00100 mappings (Inner/Outer Uncacheable in xsc3 parlance, Uncached Normal in ARMv6 parlance). The ARMv6 ARM explicitly says that any accesses to Normal memory can be merged, which makes Normal memory more suitable for _wc mappings than Device or Strongly Ordered memory, as the latter two mapping types are guaranteed to maintain transaction number, size and order. We use the Uncached variety of Normal mappings for the same reason that we can't use C=1 mappings on ARMv5. The xsc3 Architecture Specification documents TEXCB=00100 as being Uncacheable and allowing coalescing of writes, which is also just what we need.

This thinko results in a possible endless loop in the clockevents code, when the return comparison fails due to the 64bit/332bit unawareness. unsigned long cnt = (u32) hpet_read() + delta can wrap over 32bit. but the final compare will fail and return -ETIME causing endless loops.

If addinitrd was not used, the area contains garbage so probing there might misdetect initrd header (magic number is not strictly robust). This patch introduces CONFIG_PROBE_INITRD_HEADER to explicitly enable this probing.

The suspected reason for the problem is that signal_struct maintains it's own utime and stime (of exited tasks), these are not updated using the new task_utime() routine, hence sig->utime can go backwards and cause the same problem to occur (sig->utime, adds tsk->utime and not task_utime()). This patch fixes the problem TODO: using max(task->prev_utime, derived utime) works for now, but a more generic solution is to implement cputime_max() and use the cputime_gt() function for comparison.

The C1E idle patches made this prominent on AMD/RS690 chipsets, where the HPET runs with 25MHz. Set it to 5us which seems to be a reasonable value and fixes the problems on the bug reporters machines. We have a further sanity check now in the clock events, which increases the delta when it is not sufficient. Signed-off-by: Thomas Gleixner Tested-by: Luiz Fernando N.

The clockevents code needs to enforce an interrupt event on the clock event device in some cases. The enforcement code was stupid and naive, as it just added the minimum delta to the current time and tried to reprogram the device. When the minimum delta is too small, then this loops forever. Add a sanity check. Allow reprogramming to fail 3 times, then print a warning and double the minimum delta value to make sure, that this does not happen again. Use the same function for both tick-oneshot and tick-broadcast code.

Multiple shutdowns are not critical, but useless waste of time. Multiple initializations are simply broken. Another CPU might have the device in use already after the first initialization and the second init could just render it unusable again.

We need to make sure that the device is programmed enforced so the interrupt handler engine starts working. Split out the reprogramming function from tick_program_event() and call it with the device, which was handed in to tick_setup_oneshot(). Set the force argument, so the devices is firing an interrupt.

The clockevents code stores the new expiry value in the clock events device next_event field only when the programming time has not been elapsed yet. The loop in question calculates the new expiry value from the next_event value and therefor never increases.

The new clockevent ends up with clockevents_handle_noop as event handler, resulting in no timer activity. The problematic path seems to be * old device already has hrtimer_interrupt as the event_handler * new clockevent device registers with a higher rating * tick_check_new_device() is called * clockevents_exchange_device() gets called * old->event_handler is set to clockevents_handle_noop * tick_setup_device() is called for the new device * which sets new->event_handler using the old->event_handler which is noop. Change the ordering so that new device inherits the proper handler. This does not have any issue in normal case as most likely all the clockevent devices are setup before the highres switch. But, can potentially be affecting some corner case where HPET force detect happens after the highres switch. This was a problem with HPET in MSI mode code that we have been experimenting with.

This patch fixes a problem within the SH implementation of resume_kernel code, that implements in assembly the bulk of preempt_schedule_irq function without taking care of the extra code needed to handle the BKL preemptible. The patch basically consists of removing this asm code and calling the common C implementation (see kernel/sched.c) as other archs do. Another change is the missing 'cli' macro invocation at the beginning of the resume_kernel.

This results in less pointer hopping when many fingers are on the trackpad. In addition, a finger counting method based on pressure information from all fingers is introduced. Together with a pressure hysteresis window, this yields a more stable counting of the number of fingers on the trackpad.

When using the sonixb driver in a dark room and given that the autoexposure algorithm starts with a setting most suitable for daylight, the picture produced by the cam may actually be 100% black leading to a avg_lum value of 0, so an avg_lum value of 0 does not always signal an exposure settings change (which it normally does). This patch adds a check for the really black image case and stops dropping all frames as invalid in this case.

It also removes an usb-id from sn9c102 for one more unsupported bridge sensor combo.

Thus, instead of looking at the resource number to determine whether it was a bridge resource or a regular resource (they have different alignment rules), we should just ask the resource for its alignment directly. The reason this broke only cardbus resources was that for the other types of resources, the old way of deciding alignment actually still happened to work. But CardBus bridge resources had been changed by commit 934b7024f0ed29003c95cef447d92737ab86dc4f ("Fix cardbus resource allocation") to look more like regular resources than PCI bridge resources from an alignment handling standpoint.

The fix is to use only one parameter for the buffer size - there is no need to differentiate between the buffer size and the PCI mapping size since the extra 64 bytes can actually be used by the FW to align the Ethernet payload to 64 bytes.

The proper behaviour is to keep all succeded devices registered; 4) both n_devs and minor were using 0 as permissions. Better to have them with 0444. With the current patch, if n_devs specify a very large value, it will register all possible devices. For example, on a machine without any other V4L drivers loaded, with this patch, we will have something like: vivi: V4L2 device registered as /dev/video0 vivi: V4L2 device registered as /dev/video1 vivi: V4L2 device registered as /dev/video2 ... vivi: V4L2 device registered as /dev/video31 video_register_device_index: get_index failed Video Technology Magazine Virtual Video Capture Board ver 0.5.0 successfully loaded. 5) The number of allocated devices on success is now kept at n_devs: $ cat /sys/module/vivi/parameters/n_devs 32 Thanks to Henne for pointing that there were some issues at vivi.

A side-effect of this is that the decision is now made once for each contiguous section in the LMB array rather than for each page individually. This can often mean that the whole of the linear mapping ends up being executable. This reverts to the previous behaviour, where individual pages are checked for being part of the kernel text or not, by moving the check back down into htab_bolt_mapping.

This has been bisected to commit bfc0f59 "x86: merge tsc calibration". The unification of the TSC code adopted mostly the 64bit code, which prefers PMTIMER/HPET over the PIT calibration. Larrys system has an AMD K6 CPU. Such systems are known to have PMTIMER incarnations which run at double speed. This results in a miscalibration of the TSC by factor 0.5. So the resulting calibrated CPU/TSC speed is half of the real CPU speed, which means that the TSC based delay loop will run half the time it should run. That might explain why the b43legacy driver went berserk. On the other hand we know about systems, where the PIT based calibration results in random crap due to heavy SMI/SMM disturbance. On those systems the PMTIMER/HPET based calibration logic with SMI detection shows better results. According to Alok also virtualized systems suffer from the PIT calibration method. The solution is to use a more wreckage aware aproach than the current either/or decision. 1) reimplement the retry loop which was dropped from the 32bit code during the merge. It repeats the calibration and selects the lowest frequency value as this is probably the closest estimate to the real frequency 2) Monitor the delta of the TSC values in the delay loop which waits for the PIT counter to reach zero. If the maximum value is significantly different from the minimum, then we have a pretty safe indicator that the loop was disturbed by an SMI. 3) keep the pmtimer/hpet reference as a backup solution for systems where the SMI disturbance is a permanent point of failure for PIT based calibration 4) do the loop iteration for both methods, record the lowest value and decide after all iterations finished. 5) Set a clear preference to PIT based calibration when the result makes sense. The implementation does the reference calibration based on HPET/PMTIMER around the delay, which is necessary for the PIT anyway, but keeps separate TSC values to ensure the "independency" of the resulting calibration values. Tested on various 32bit/64bit machines including Geode 266Mhz, AMD K6 (affected machine with a double speed pmtimer which I grabbed out of the dump), Pentium class machines and AMD/Intel 64 bit boxen.

This is a regression intruduced into 2.6.26 by commit adc782dae6c4c0f6fb679a48a544cfbcd79ae3dc Author: Matt Mackall Date: Tue Apr 29 01:03:07 2008 -0700 random: simplify and rename credit_entropy_store credit_entropy_bits() does: spin_lock_irqsave(&r->lock, flags); ... if (r->entropy_count > r->poolinfo->POOLBITS) r->entropy_count = r->poolinfo->POOLBITS; so there is a time window in which this BUG_ON(): static size_t account(struct entropy_store *r, size_t nbytes, int min, int reserved) { unsigned long flags; BUG_ON(r->entropy_count > r->poolinfo->POOLBITS); /* Hold lock while accounting */ spin_lock_irqsave(&r->lock, flags); can trigger. We could fix this by moving the assertion inside the lock, but it seems safer and saner to revert to the old behaviour wherein entropy_store.entropy_count at no time exceeds entropy_store.poolinfo->POOLBITS.

The purpose of the patch is to remove the spin_lock around the read in the function pm_qos_requirement - since spinlocks can sleep in -rt and this function is called from idle. CPU_IDLE polls the target_value's of some of the pm_qos parameters from the idle loop causing sleeping locking warnings. Changing the target_value to an atomic avoids this issue. Remove the spinlock in pm_qos_requirement by making target_value an atomic type.

I have just fixed it up so it applies without fuzz to upstream kernels. Original patch and description from Shyam kumar Iyer: The issue [ibft module not displaying targets with short names] is because of an offset calculatation error in the iscsi_ibft.c code. Due to this error directory structure for the target in /sys/firmware/ibft does not get created and so the initiator is unable to connect to the target. Note that this bug surfaced only with an name that had a short section at the end. eg: "iqn.1984-05.com.dell:dell". It did not surface when the iqn's had a longer section at the end. eg: "iqn.2001-04.com.example:storage.disk2.sys1.xyz" So, the eot_offset was calculated such that an extra 48 bytes i.e. the size of the ibft_header which has already been accounted was subtracted twice. This was not evident with longer iqn names because they would overshoot the total ibft length more than 48 bytes and thus would escape the bug.

(Each CPU can cache node_free_pages/16 pages) It is used for page table cache. exit() will increase the cache size, while fork() consumes it. So for example if an apache-style application runs (one parent and many child model), one CPU process will fork() while another CPU will process the middleware work and exit(). At that time, the CPU on which the parent runs doesn't have page table cache at all. Others (on which children runs) have maximum caches. QList_max = (#ofCPUs - 1) x Free / 16 => QList_max / (Free + QList_max) = (#ofCPUs - 1) / (16 + #ofCPUs - 1) So, How much quicklist memory is used in the maximum case? This is proposional to # of CPUs because the limit of per cpu quicklist cache doesn't see the number of cpus. Above calculation mean Number of CPUs per node 2 4 8 16 ============================== ==================== QList_max / (Free + QList_max) 5.8% 16% 30% 48% Wow!

This is not memory leak but doesn't seem good. % cat /proc/meminfo MemTotal: 7701568 kB MemFree: 4724672 kB (snip) Quicklists: 844800 kB because - My machine spec is number of numa node: 2 number of cpus: 8 (4CPU x2 node) total mem: 8GB (4GB x2 node) free mem: about 5GB - Then, 4.7GB x 16% ~= 880MB. So, Quicklist can use 800MB. So, if following spec machine run that program CPUs: 64 (8cpu x 8node) Mem: 1TB (128GB x8node) Then, quicklist can waste 300GB (= 1TB x 30%). It is too large. So, I don't like cache policies which is proportional to # of cpus. My patch changes the number of caches from: per-cpu-cache-amount = memory_on_node / 16 to per-cpu-cache-amount = memory_on_node / 16 / number_of_cpus_on_node.

As Robert Rex pointed out this is wrong. Yes, the re-parenting itself works correctly, but if the reparented task exits it needs ->parent->nsproxy->pid_ns in do_notify_parent(), and if the main thread is zombie its ->nsproxy was already cleared by exit_task_namespaces(). Introduce the new function, find_new_reaper(), which finds the new ->parent for the re-parenting and changes ->child_reaper if needed. Kill the now unneeded exit_child_reaper(). Also move the changing of ->child_reaper from zap_pid_ns_processes() to find_new_reaper(), this consolidates the games with ->child_reaper and makes it stable under tasklist_lock.

Yes, we have already killed all tasks in this namespace, and sys_wait4() doesn't see any child. But this doesn't mean ->children list is empty, we may have EXIT_DEAD tasks which are not visible to do_wait(). In that case the subsequent forget_original_parent() will crash the kernel because it will try to re-parent these tasks to the NULL reaper. Even if there are no childs, it is not good that forget_original_parent() uses reaper == NULL. Change the code to set ->child_reaper = init_pid_ns.child_reaper instead. We could use pid_ns->parent->child_reaper as well, I think this does not really matter. These EXIT_DEAD tasks are not visible to the new ->parent after re-parenting, they will silently do release_task() eventually. Note that we must change ->child_reaper, otherwise forget_original_parent() will use reaper == father, and in that case we will hit the (correct) BUG_ON(!list_empty(&father->children)).

This bug has been around for a LONG time. The MM warning is from late 2005, but the driver merged a year later ... so I'm puzzled why nobody noticed this before now. The fix involves noting that this buffer shouldn't be DMA-coherent; it's just used for normal DMA writes. So replace it with standard kmalloc() buffering and DMA mapping calls. This is the quickie fix. A better one would not rely on allocating large bounce buffers. (Note that dma_alloc_coherent could have failed too, but that case was ignored... kmalloc is a bit more likely to fail though.)

I did fsstress test heavily to 2.6.27-rc1, and found that dio write still sometimes got EIO through this test. The patch above fixed race between freeing buffer(dio) and committing transaction(jbd) but I discovered that there is another race, freeing buffer(dio) and ext3/4_ordered_writepage. : background_writeout() ->write_cache_pages() ->ext3_ordered_writepage() walk_page_buffers() -> take a bh ref block_write_full_page() -> unlock_page : <- end_page_writeback : <- race! (dio write->try_to_release_page fails) walk_page_buffers() ->release a bh ref ext3_ordered_writepage holds bh ref and does unlock_page remaining taking a bh ref, so this causes the race and failure of try_to_release_page. To fix this race, I used the approach of falling back to buffered writes if try_to_release_page() fails on a page.

This patch addresses an issue with the locking order. ath_rx_flush_tid() uses spin_lock/unlock_bh when IRQs are disabled in sta_notify by mac80211. As node clean up is still pending with ath9k and this problematic portion of the code is expected to change anyway, thinking of a proper fix may not be worthwhile. So having this interim fix helps the users to get rid of the kernel warning message. Pasted the kernel warning message for reference. kernel: ath0: No ProbeResp from current AP 00:1b:11:60:7a:3d - assume out of range kernel: ------------[ cut here ]------------ kernel: WARNING: at kernel/softirq.c:136 local_bh_enable+0x3c/0xab() kernel: Pid: 1029, comm: ath9k Not tainted 2.6.27-rc4-wt-w1fi-wl kernel: kernel: Call Trace: kernel: [] warn_on_slowpath+0x51/0x77 kernel: [] check_preempt_wakeup+0xf3/0x123 kernel: [] autoremove_wake_function+0x9/0x2e kernel: [] local_bh_enable+0x3c/0xab kernel: [] ath_rx_node_cleanup+0x38/0x6e [ath9k] kernel: [] ath_node_detach+0x3b/0xb6 [ath9k] kernel: [] ath9k_sta_notify+0x12b/0x165 [ath9k] kernel: [] queue_work+0x1d/0x49 kernel: [] add_todo+0x70/0x99 [mac80211] kernel: [] __sta_info_unlink+0x16b/0x19e [mac80211] kernel: [] sta_info_unlink+0x18/0x43 [mac80211] kernel: [] ieee80211_associated+0xaa/0x16d [mac80211] kernel: [] ieee80211_sta_work+0x4fb/0x6b4 [mac80211] kernel: [] thread_return+0x30/0xa9 kernel: [] ieee80211_sta_work+0x0/0x6b4 [mac80211] kernel: [] run_workqueue+0xb1/0x17a kernel: [] worker_thread+0xd0/0xdb kernel: [] autoremove_wake_function+0x0/0x2e kernel: [] worker_thread+0x0/0xdb kernel: [] kthread+0x47/0x75 kernel: [] schedule_tail+0x18/0x50 kernel: [] child_rip+0xa/0x11 kernel: [] kthread+0x0/0x75 kernel: [] child_rip+0x0/0x11 kernel: kernel: ---[ end trace e9bb5da661055827 ]--- Signed-off-by: Senthil Balasubramanian Signed-off-by: John W.

This ends occupying the same memory area with the first dentry in other union members (structures; usually drop_unencrypted). Consequently, debugfs operations on default_key symlinks and drop_unencrypted entry are using the same dentry pointer even though they are supposed to be separate ones. This can lead to removing entries incorrectly or potentially leaving something behind since one of the dentry pointers gets lost. Fix this by moving the default_key dentry to a new struct (common_debugfs) that contains dentries (more to be added in future) that are shared by all vif types. The debugfs union must only be used for vif type-specific entries to avoid this type of pointer corruption. Signed-off-by: Jouni Malinen Acked-by: Johannes Berg Signed-off-by: John W.

In general this means you have to set the multicast addresses twice to get the behaviour you want. If we were multicasting, and reduce the number of addresses we are multicasting to, then the driver would write uninitialised data from the stack into the group addresses to multicast to. Only write the multicast addresses we have specifically set. Signed-off-by: David Kilroy Signed-off-by: John W.

David Wagner added (among other things) that copy_to_user could be probably used here. Ingo Oeser suggested to use simple_read_from_buffer() here. The conclusion is that proc_do_xprt doesn't check for userside buffer size indeed so fix this by using Ingo's suggestion.

Although there's no kernel support for the Java hardware yet, we need to be able to recover from this situation and keep the system running. This patch adds code to detect and fixup this situation in the critical exception handler and terminate the faulting process. We may have to rethink how to handle this more gracefully when the necessary kernel support for hardware-accelerated Java is added.

The rcu lock is only needed while walking the linked list as uninteresting devices (failed or spares) can be removed at any time. So only take the rcu lock while actually walking the linked list. Take a refcount on the rdev during the time when we drop the lock and do the memalloc to start IO. When we return to the locked code, all the interesting devices on the list will not have moved, so we can simply use list_for_each_continue_rcu to pick up where we left off. Signed-off-by: NeilBrown commit 271f5a9b8f8ae0db95de72779d115c9d0b9d3cc5 Author: NeilBrown Date: Mon Sep 1 12:32:52 2008 +1000 Remove invalidate_partition call from do_md_stop. When stopping an md array, or just switching to read-only, we currently call invalidate_partition while holding the mddev lock. The main reason for this is probably to ensure all dirty buffers are flushed (invalidate_partition calls fsync_bdev). However if any dirty buffers are found, it will almost certainly cause a deadlock as starting writeout will require an update to the superblock, and performing that updates requires taking the mddev lock - which is already held. This deadlock can be demonstrated by running "reboot -f -n" with a root filesystem on md/raid, and some dirty buffers in memory. All other calls to stop an array should already happen after a flush. The normal sequence is to stop using the array (e.g. umount) which will cause __blkdev_put to call sync_blockdev. Then open the array and issue the STOP_ARRAY ioctl while the buffers are all still clean. So this invalidate_partition is normally a no-op, except for one case where it will cause a deadlock. So remove it. This patch possibly addresses the regression recored in http://bugzilla.kernel.org/show_bug.cgi?id=11460 and http://bugzilla.kernel.org/show_bug.cgi?id=11452 though it isn't yet clear how it ever worked.

I don't think NFS problems should be all that noisy. Luckily there's a reasonably easy way to distingush this case. Don't report task softlockup warnings for tasks in TASK_KILLABLE state, which is used by the network file systems. I believe this patch is a 2.6.27 candidate.

It wasn't really right to begin with (there's a better fix for the problem with e820 reservations clashing with PCI BAR's pending), but it also actually causes more regressions, so it should be reverted even before the better fix is finalized. Rafael reports that this commit broke AHCI detection, and thus causes the kernel to not boot on his quad core test box. Reported-and-bisected-by: Rafael J.

This should fix the XORP build failure reported by Jose Calhariz, the debain package maintainer. Nothing originally in linux/mroute.h was exported to userspace ever, but some of this stuff started to be when it was moved into this new linux/pim.h, and that was wrong. If we didn't provide these definitions for 10 years we can reasonably expect that applications defined this stuff locally or used GLIBC headers providing the protocol definitions. And as such the only result of this can be conflict and userland build breakage. Signed-off-by: David S.

In our case, this leads to the DACs being misconfigured to I2S sample format, which results in a wrong output level and horrible distortions on samples louder than -6 dB. To fix this, we need to wait until the new master clock signal has become stable before doing SPI writes.

That function does not currently call generic_write_checks() so the file position isn't being properly set when the file is opened with O_APPEND. It's also not doing the other "normal" checks that should be done for a write call. The problem is currently that when you open a file with O_APPEND on a mount with the directio mount option, the file position is set to the beginning of the file. This makes any subsequent writes clobber the data in the file starting at the beginning. This seems to fix the problem in cursory testing. It is, however important to note that NFS disallows the combination of (O_DIRECT|O_APPEND). If my understanding is correct, the concern is races with multiple clients appending to a file clobbering each others' data. Since the write model for CIFS and NFS is pretty similar in this regard, CIFS is probably subject to the same sort of races. What's unclear to me is why this is a particular problem with O_DIRECT and not with buffered writes... Regardless, disallowing O_APPEND on an entire mount is probably not reasonable, so we'll probably just have to deal with it and reevaluate this flag combination when we get proper support for O_DIRECT. In the meantime this patch at least fixes the existing problem.

This patch makes Linux PNPACPI ignore the bit. The ACPI spec contains examples of PCI Interrupt Link devices marked as ResourceProducers, but many BIOSes mark them as ResourceConsumers. I also checked with a Windows contact, who said: Windows uses only "resource consumer" when dealing with interrupts. There's no useful way of looking at a resource producer of interrupts. ... NT-based Windows largely infers the producer/consumer stuff from the device type and ignores the bits in the namespace. This was necessary because Windows 98 ignored them and early namespaces contained random junk. The reason I want to change this is because if PNPACPI devices exclude ResourceProducer IRQ resources, we can't write PNP drivers for those devices. For example, on machines such as the the HP rx7620, rx7640, rx8620, rx8640, and Superdome, HPET interrupts are ResourceProducers. The HPET driver currently has to use acpi_bus_register_driver() and do its own _CRS parsing, even though it requires absolutely no ACPI-specific functionality. It would be better if the HPET driver were a PNP driver and took advantage of the _CRS parsing built into PNPACPI. This producer/consumer check was originally added here: http://git.kernel.org/?p=linux/kernel/git/torvalds/linux-2.6.git;a=commitdiff;h=2b8de5f50e4a302b83ebcd5b0120621336d50bd6 to fix this bug: http://bugzilla.kernel.org/show_bug.cgi?id=6292 However, the bug was related only to memory and I/O port resources, where the distinction is sensible and important to Linux. Given that the distinction is muddled for IRQ resources, I think it was a mistake to add the check there.

The patch fixes CPU hotplug handling issues in the current cpusets code. Namely circular locking in rebuild_sched_domains() and unsafe access to the cpu_online_map in the cpuset cpu hotplug handler. This version includes changes suggested by Paul Jackson (naming, comments, style, etc). I also got rid of the separate workqueue thread because it is now safe to call get_online_cpus() from workqueue callbacks. Here are some more details: rebuild_sched_domains() is the only way to rebuild sched domains correctly based on the current cpuset settings. What this means is that we need to be able to call it from different contexts, like cpu hotplug for example. Also latest scheduler code in -tip now calls rebuild_sched_domains() directly from functions like arch_reinit_sched_domains(). In order to support that properly we need to rework cpuset locking rules to avoid circular dependencies, which is what this patch does. New lock nesting rules are explained in the comments. We can now safely call rebuild_sched_domains() from virtually any context. The only requirement is that it needs to be called under get_online_cpus(). This allows cpu hotplug handlers and the scheduler to call rebuild_sched_domains() directly. The rest of the cpuset code now offloads sched domains rebuilds to a workqueue (async_rebuild_sched_domains()). This version of the patch addresses comments from the previous review. I fixed all miss-formated comments and trailing spaces. I also factored out the code that builds domain masks and split up CPU and memory hotplug handling. This was needed to simplify locking, to avoid unsafe access to the cpu_online_map from mem hotplug handler, and in general to make things cleaner. The patch passes moderate testing (building kernel with -j 16, creating & removing domains and bringing cpus off/online at the same time) on the quad-core2 based machine. It passes lockdep checks, even with preemptable RCU enabled. This time I also tested in with suspend/resume path and everything is working as expected.

Since a separate lock is used to protect the RDMA_READ completion queue, a race exists between the dto_tasklet and the svc_rdma_recvfrom thread where the dto_tasklet sets the XPT_DATA bit and adds I/O to the read-completion queue. Concurrently, the recvfrom thread checks the generic queue, finds it empty and resets the XPT_DATA bit. A subsequent svc_xprt_enqueue will fail to enqueue the transport for I/O and cause the transport to "stall". The fix is to protect both lists with the same lock and set the XPT_DATA bit with this lock held. Signed-off-by: Tom Tucker Signed-off-by: J. Bruce Fields
