2010-03-22netfilter: xt_recent: fix regression in rules using a zero hit_countPatrick McHardy1-1/+1
Commit 8ccb92ad (netfilter: xt_recent: fix false match) fixed supposedly false matches in rules using a zero hit_count. As it turns out there is nothing false about these matches and people are actually using entries with a hit_count of zero to make rules dependant on addresses inserted manually through /proc. Since this slipped past the eyes of three reviewers, instead of reverting the commit in question, this patch explicitly checks for a hit_count of zero to make the intentions more clear.

2010-03-22ppc64 sys_ipc breakage in 2.6.34-rc2Anton Blanchard1-1/+1
I chased down a fail on ppc64 on 2.6.34-rc2 where an application that uses shared memory was getting a SEGV. Commit baed7fc9b580bd3fb8252ff1d9b36eaf1f86b670 ("Add generic sys_ipc wrapper") changed the second argument from an unsigned long to an int. When we call shmget the system call wrappers for sys_ipc will sign extend second (ie the size) which truncates it. It took a while to track down because the call succeeds and strace shows the untruncated size :) The patch below changes second from an int to an unsigned long which fixes shmget on ppc64 (and I assume s390, sparc64 and mips64). Signed-off-by: Anton Blanchard <[email protected]> -- I assume the function prototypes for the other IPC methods would cause us to sign or zero extend second where appropriate (avoiding any security issues). Come to think of it, the syscall wrappers for each method should do that for us as well. Signed-off-by: Linus Torvalds <[email protected]>
2010-03-22x86 / perf: Fix suspend to RAM on HP nx6325Rafael J. Wysocki1-3/+5
Commit 3f6da3905398826d85731247e7fbcf53400c18bd (perf: Rework and fix the arch CPU-hotplug hooks) broke suspend to RAM on my HP nx6325 (and most likely on other AMD-based boxes too) by allowing amd_pmu_cpu_offline() to be executed for CPUs that are going offline as part of the suspend process. The problem is that cpuhw->amd_nb may be NULL already, so the function should make sure it's not NULL before accessing the object pointed to by it. Signed-off-by: Rafael J.

2010-03-22NFS: don't try to decode GETATTR if DELEGRETURN returned errorJeff Layton1-0/+2
The reply parsing code attempts to decode the GETATTR response even if the DELEGRETURN portion of the compound returned an error. The GETATTR response won't actually exist if that's the case and we're asking the parser to read past the end of the response. This bug is fairly benign. The parser catches this without reading past the end of the response and decode_getfattr returns -EIO. Earlier kernels however had decode_op_hdr using the READ_BUF macro, and this bug would make this printk pop any time the client got an error from a delegreturn: kernel: decode_op_hdr: reply buffer overflowed in line XXXX More recent kernels seem to have replaced this printk with a dprintk.

2010-03-22[ARM] locomo: fix unpaired spin_lock_irqsaveH Hartley Sweeten1-3/+3
The function locomo_m62332_senddata sends a three byte i2c message to a M62332 DAC. This entire function is guarded with a spin_lock_irqsave at the start of the function and a spin_unlock_irqrestore at the end. As each byte is transferred, the i2c ACK from the DAC is checked. Currently, if the ACK is missing the function simply returns without the unlock. It also leaves the i2c bus in an invalid state since the last byte transferred did not have a "stop" condition and leave the bus idle. Fix this by adding an exit path using goto.

2010-03-22[ARM] locomo: fix SPI register offsetH Hartley Sweeten1-2/+2
The locomo spi registers are all defined in locomo.h as offsets from the first spi register LOCOMO_SPI (0x60), which is itself an offset from the locomo base address. To correctly access these registers LOCOMO_SPI must always be included in the address calculation. There are two places in locomo.c where this is not done. The first one, in locomo_suspend, actually results in a write to LOCOMO_ST instead of LOCOMO_SPICT. The second is in __locomo_probe and results in a write to LOCOMO_MCSX2 instead of LOCOMO_SPIIE. Fix these by including LOCOMO_SPI in the calculation. Signed-off-by: H Hartley Sweeten <[email protected]> Signed-off-by: Eric Miao <[email protected]>

2010-03-21ipv4: Don't drop redirected route cache entry unless PTMU actually expiredGuenter Roeck1-1/+2
TCP sessions over IPv4 can get stuck if routers between endpoints do not fragment packets but implement PMTU instead, and we are using those routers because of an ICMP redirect. Setup is as follows MTU1 MTU2 MTU1 A--------B------C------D with MTU1 > MTU2. A and D are endpoints, B and C are routers. B and C implement PMTU and drop packets larger than MTU2 (for example because DF is set on all packets). TCP sessions are initiated between A and D. There is packet loss between A and D, causing frequent TCP retransmits. After the number of retransmits on a TCP session reaches tcp_retries1, tcp calls dst_negative_advice() prior to each retransmit. This results in route cache entries for the peer to be deleted in ipv4_negative_advice() if the Path MTU is set. If the outstanding data on an affected TCP session is larger than MTU2, packets sent from the endpoints will be dropped by B or C, and ICMP NEEDFRAG will be returned. A and D receive NEEDFRAG messages and update PMTU. Before the next retransmit, tcp will again call dst_negative_advice(), causing the route cache entry (with correct PMTU) to be deleted. The retransmitted packet will be larger than MTU2, causing it to be dropped again. This sequence repeats until the TCP session aborts or is terminated. Problem is fixed by removing redirected route cache entries in ipv4_negative_advice() only if the PMTU is expired. Signed-off-by: Guenter Roeck <[email protected]> Signed-off-by: David S.
