2011-01-25NLM: Fix "kernel BUG at fs/lockd/host.c:417!" or ".../host.c:283!"Chuck Lever1-4/+5
Nick Bowler <[email protected]> reports: > We were just having some NFS server troubles, and my client machine > running 2.6.38-rc1+ (specifically, commit 2b1caf6ed7b888c95) crashed > hard (syslog output appended to this mail). > > I'm not sure what the exact timeline was or how to reproduce this, > but the server was rebooted during all this.

However, I recently updated my nfs-utils (on the client) to > version 1.2.3, so that might be related as well. [ BUG output redacted ] When done searching, the for_each_host loop in next_host_state() falls through and returns the final host on the host chain without bumping it's reference count. Since the host's ref count is only one at that point, releasing the host in nlm_host_rebooted() attempts to destroy the host prematurely, and therefore hits a BUG(). Likely, the original intent of the for_each_host behavior in next_host_state() was to handle the case when the host chain is empty. Searching the chain and finding no suitable host to return needs to be handled as well. Defensively restructure next_host_state() always to return NULL when the loop falls through.

2011-01-25NFS: Prevent memory allocation failure in nfsacl_encode()Chuck Lever4-13/+31
nfsacl_encode() allocates memory in certain cases. This of course is not guaranteed to work. Since commit 9f06c719 "SUNRPC: New xdr_streams XDR encoder API", the kernel's XDR encoders can't return a result indicating possibly a failure, so a memory allocation failure in nfsacl_encode() has become fatal (ie, the XDR code Oopses) in some cases. However, the allocated memory is a tiny fixed amount, on the order of 40-50 bytes. We can easily use a stack-allocated buffer for this, with only a wee bit of nose-holding.

2011-01-25NFS: nfsacl_{encode,decode} should return signed integerChuck Lever2-8/+28
Clean up. The nfsacl_encode() and nfsacl_decode() functions return negative errno values, and each call site verifies that the returned value is not negative. Change the synopsis of both of these functions to reflect this usage. Document the synopsis and return values.

To address this, prevent the NFS direct I/O engine from completing async iocbs when the forward path returns an error without starting any I/O. This fix appears to survive ^C during both "xfstest no. 208" and "fsx -Z." It's likely this bug has existed for a very long while, as we are seeing very similar symptoms in OEL 5. Copying stable.

2011-01-25PM / Runtime: Don't enable interrupts while running in_interruptAlan Stern1-3/+6
This patch (as1445) fixes a bug in the runtime PM core left over from the addition of the no_callbacks flag. If this flag is set then it is possible for rpm_suspend() to be called in_interrupt, so when releasing spinlocks it's important not to re-enable interrupts. To avoid an unnecessary save-and-restore of the interrupt flag, the patch also inlines a pm_request_idle() call. This fixes Bugzilla #27482. (The offending code was added in 2.6.37, so it's not necessary to apply this to any earlier stable kernels.)

2011-01-25ARM: 6635/2: Configure reference clock for Versatile Express timersPawel Moll2-0/+15
Timers on Versatile Express mainboard are used as system clock/event sources. Driver assumes that they are clocked with 1MHz signal. Old V2M firmware apparently configured it by default, but on newer boards one can observe that "sleep 1" command takes over 30 seconds to finish, as the timers are fed with 32kHz instead... This patch performs required magic and also removes code clearing timer's control registers, as exactly the same operations are performed by the timer driver few jiffies later.

This patch makes it symmetric so user space and drivers do not have to handle the CEE version and IEEE DCBx versions differently.

2011-01-24tcp: fix bug in listening_get_next()Eric Dumazet1-1/+0
commit a8b690f98baf9fb19 (tcp: Fix slowness in read /proc/net/tcp) introduced a bug in handling of SYN_RECV sockets. st->offset represents number of sockets found since beginning of listening_hash[st->bucket]. We should not reset st->offset when iterating through syn_table[st->sbucket], or else if more than ~25 sockets (if PAGE_SIZE=4096) are in SYN_RECV state, we exit from listening_get_next() with a too small st->offset Next time we enter tcp_seek_last_pos(), we are not able to seek past already found sockets.
