The first one is a cut-n-paste bug, instead of disabling the clock when request_irq() fails, it enabled it once more. The second one fixes a debug printout, AT91_SSC_IER is write only, AT91_SSC_IMR is readable (the printed string actually says imr).

| aca5139 | Pavel Emelyanov | 08 May 2008, 08:24:25 UTC | netns: Fix arbitrary net_device-s corruptions on net_ns stop. When a net namespace is destroyed, some devices (those, not killed on ns stop explicitly) are moved back to init_net. The problem, is that this net_ns change has one point of failure - the __dev_alloc_name() may be called if a name collision occurs (and this is easy to trigger). This allocator performs a likely-to-fail GFP_ATOMIC allocation to find a suitable number. Other possible conditions that may cause error (for device being ns local or not registered) are always false in this case. So, when this call fails, the device is unregistered. But this is *not* the right thing to do, since after this the device may be released (and kfree-ed) improperly. E. g. bridges require more actions (sysfs update, timer disarming, etc.), some other devices want to remove their private areas from lists, etc. I. e. arbitrary use-after-free cases may occur. The proposed fix is the following: since the only reason for the dev_change_net_namespace to fail is the name generation, we may give it a unique fall-back name w/o %d-s in it - the dev<ifindex> one, since ifindexes are still unique. So make this change, raise the failure-case printk loglevel to EMERG and replace the unregister_netdevice call with BUG().

The first requests will elicit error responses from the receiver, causing the SIP helper to flush the RTP expectations even though we might still see a positive response. Note the sequence number of the last INVITE request that contained a media description and only flush the expectations when receiving a negative response for that sequence number.

The reason is that it tries to clean up the macvlan_port pointer on the macvlan device itself instead of the underlying device.

| 62ab222 | Ilpo Järvinen | 08 May 2008, 08:09:11 UTC | tcp FRTO: SACK variant is errorneously used with NewReno Note: there's actually another bug in FRTO's SACK variant, which is the causing failure in NewReno case because of the error that's fixed here. I'll fix the SACK case separately (it's a separate bug really, though related, but in order to fix that I need to audit tp->snd_nxt usage a bit). There were two places where SACK variant of FRTO is getting incorrectly used even if SACK wasn't negotiated by the TCP flow. This leads to incorrect setting of frto_highmark with NewReno if a previous recovery was interrupted by another RTO. An eventual fallback to conventional recovery then incorrectly considers one or couple of segments as forward transmissions though they weren't, which then are not LOST marked during fallback making them "non-retransmittable" until the next RTO. In a bad case, those segments are really lost and are the only one left in the window. Thus TCP needs another RTO to continue. The next FRTO, however, could again repeat the same events making the progress of the TCP flow extremely slow. In order for these events to occur at all, FRTO must occur again in FRTOs step 3 while the key segments must be lost as well, which is not too likely in practice. It seems to most frequently with some small devices such as network printers that *seem* to accept TCP segments only in-order. In cases were key segments weren't lost, things get automatically resolved because those wrongly marked segments don't need to be retransmitted in order to continue. I found a reproducer after digging up relevant reports (few reports in total, none at netdev or lkml I know of), some cases seemed to indicate middlebox issues which seems now to be a false assumption some people had made. Bugzilla #10063 _might_ be related. Damon L. Chesser <damon@damtek.com> had a reproducable case and was kind enough to tcpdump it for me. With the tcpdump log it was quite trivial to figure out.

Also, we align the stack even in non-SA_ONSTACK cases so that signals due to bad stack alignment can be delivered properly. This makes such errors easier to debug and recover from.

So, swap the tests so the set_bit() isn't shadowed by the &&. If we've disarmed the piobufs, then we need to unconditionally set DISARMED. So, move it out from the overly protective if at the bottom. in sdma_abort_task() Abort_task was written knowing that the SDMA engine would always be reset (and restarted) on error. A recent change broke that fundamental assumption by taking the restart portion and making it conditional on a link status change. But, SDMA can go boom without a link status change in some conditions.

We also have to reduce the pio update threshold if we have fewer kernel buffers than the existing threshold. Clean up the initialization a bit to get ordering safer and more sensible, and use the existing ipath_chg_kernavail call to do init, rather than doing it separately. Drop unnecessary clearing of pio buffer on pio parity error. Drop incorrect updating of pioavailshadow when exitting freeze mode (software state may not match chip state if buffer has been allocated and not yet written). If we couldn't get a kernel buffer for a while, make sure we are in sync with hardware, mainly to handle the exitting freeze case.

As it is HMAC converts the key to a scatter and gather list. However, this doesn't work on certain platforms if the key is not allocated via kmalloc. For example, the keys from tcrypt are stored in the rodata section and this causes it to fail with HMAC on x86-64.

| dbaf2c0 | Jens Axboe | 07 May 2008, 07:48:17 UTC | block: optimize generic_unplug_device() Original patch from Mikulas Patocka <mpatocka@redhat.com> Mike Anderson was doing an OLTP benchmark on a computer with 48 physical disks mapped to one logical device via device mapper. He found that there was a slowdown on request_queue->lock in function generic_unplug_device. The slowdown is caused by the fact that when some code calls unplug on the device mapper, device mapper calls unplug on all physical disks. These unplug calls take the lock, find that the queue is already unplugged, release the lock and exit. With the below patch, performance of the benchmark was increased by 18% (the whole OLTP application, not just block layer microbenchmarks). So I'm submitting this patch for upstream. I think the patch is correct, because when more threads call simultaneously plug and unplug, it is unspecified, if the queue is or isn't plugged (so the patch can't make this worse). And the caller that plugged the queue should unplug it anyway. (if it doesn't, there's 3ms timeout).

Removes preemption requirement From: Martin Schwidefsky <schwidefsky@de.ibm.com> This patch fixes a bug with cpu bound guest on kvm-s390. Sometimes it was impossible to deliver a signal to a spinning guest. We used preemption as a circumvention. The preemption notifiers called vcpu_load, which checked for pending signals and triggered a host intercept. But even with preemption, a sigkill was not delivered immediately. This patch changes the low level host interrupt handler to check for the SIE instruction, if TIF_WORK is set. In that case we change the instruction pointer of the return PSW to rerun the vcpu_run loop. The kvm code sees an intercept reason 0 if that happens. This patch adds accounting for these types of intercept as well.
