2011-03-29watchdog: softdog.c: enhancement to optionally invoke panic instead of ↵Anithra P Janakiraman1-3/+13
reboot on timer expiry This is needed for determining the reason for failure when a softdog timeout occurs. We use softdog to watch for critical application failures and at the minimum a snapshot of the system would help to determine the cause. In such a scenario the application could fail but there isn't a softlockup as such, hence the detect softlockup feature does not help. The patch adds a module parameter soft_panic which when set to 1 causes softdog to invoke panic instead of reboot when the softdog timer expires. By invoking panic we execute kdump if it is configured and the vmcore generated by kdump should provide atleast a minimal idea of the reason for failure.

2011-03-28xfrm: Assign esn pointers when cloning a stateSteffen Klassert2-0/+28
When we clone a xfrm state we have to assign the replay_esn and the preplay_esn pointers to the state if we use the new replay detection method. To this end, we add a xfrm_replay_clone() function that allocates memory for the replay detection and takes over the necessary values from the original state.

2011-03-28cxgb3: Apply interrupt coalescing settings to all queuesAnton Blanchard1-4/+10
While testing the performance of different receive interrupt coalescing settings on a single stream TCP benchmark, I noticed two very different results. With rx-usecs=50, most of the time a connection would hit 8280 Mbps but once in a while it would hit 9330 Mbps. It turns out we are only applying the interrupt coalescing settings to the first queue and whenever the rx hash would direct us onto that queue we ran faster. With this patch applied and rx-usecs=50, I get 9330 Mbps consistently. Signed-off-by: Anton Blanchard <[email protected]> Acked-by: Divy Le Ray <[email protected]> Signed-off-by: David S.

When analysing performance of the cxgb3 on a ppc64 box I noticed that we weren't doing much GRO merging. It turns out we are limited by the number of SKB frags: #define MAX_SKB_FRAGS (65536/PAGE_SIZE + 2) With a 4kB page size we have 18 frags, but with a 64kB page size we only have 3 frags.

2011-03-28Relax si_code check in rt_sigqueueinfo and rt_tgsigqueueinfoRoland Dreier1-2/+2
Commit da48524eb206 ("Prevent rt_sigqueueinfo and rt_tgsigqueueinfo from spoofing the signal code") made the check on si_code too strict. There are several legitimate places where glibc wants to queue a negative si_code different from SI_QUEUE: - This was first noticed with glibc's aio implementation, which wants to queue a signal with si_code SI_ASYNCIO; the current kernel causes glibc's tst-aio4 test to fail because rt_sigqueueinfo() fails with EPERM. - Further examination of the glibc source shows that getaddrinfo_a() wants to use SI_ASYNCNL (which the kernel does not even define). The timer_create() fallback code wants to queue signals with SI_TIMER. As suggested by Oleg Nesterov <[email protected]>, loosen the check to forbid only the problematic SI_TKILL case.
