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.

2010-03-20ceph: fix authenticator timeoutSage Weil1-8/+1
We were failing to reconnect to services due to an old authenticator, even though we had the new ticket, because we weren't properly retrying the connect handshake, because we were calling an old/incorrect helper that left in_base_pos incorrect. The result was a failure to reconnect to the OSD or MDS (with an authentication error) if the MDS restarted after the service had been up a few hours (long enough for the original authenticator to be invalid). This was only a problem if the AUTH_X authentication was enabled. Now that the 'negotiate' and 'connect' stages are fully separated, we should use the prepare_read_connect() helper instead, and remove the obsolete one. Signed-off-by: Sage Weil <[email protected]>
2010-03-20ceph: fix inode removal from snap realm when racing with migrationSage Weil1-0/+16

2010-03-20NET_DMA: free skbs periodicallySteven J. Magnani1-20/+43
Under NET_DMA, data transfer can grind to a halt when userland issues a large read on a socket with a high RCVLOWAT (i.e., 512 KB for both). This appears to be because the NET_DMA design queues up lots of memcpy operations, but doesn't issue or wait for them (and thus free the associated skbs) until it is time for tcp_recvmesg() to return. The socket hangs when its TCP window goes to zero before enough data is available to satisfy the read. Periodically issue asynchronous memcpy operations, and free skbs for ones that have completed, to prevent sockets from going into zero-window mode. Signed-off-by: Steven J.

2010-03-19ixgbevf: Fix VF Stats accounting after resetGreg Rose3-38/+78
The counters in the 82599 Virtual Function are not clear on read. They accumulate to the maximum value and then roll over. They are also not cleared when the VF executes a soft reset, so it is possible they are non-zero when the driver loads and starts. This has all been accounted for in the code that keeps the stats up to date but there is one case that is not. When the PF driver is reset the counters in the VF are all reset to zero. This adds an additional accounting overhead into the VF driver when the PF is reset under its feet. This patch adds additional counters that are used by the VF driver to accumulate and save stats after a PF reset has been detected. Prior to this patch displaying the stats in the VF after the PF has reset would show bogus data.

Xfrm_dst keeps a reference to ipv4 rtable entries on each cached bundle. The only way to renew xfrm_dst when the underlying route has changed, is to implement dst_check for this. This is what ipv6 side does too. The problems started after 87c1e12b5eeb7b30b4b41291bef8e0b41fc3dde9 ("ipsec: Fix bogus bundle flowi") which fixed a bug causing xfrm_dst to not get reused, until that all lookups always generated new xfrm_dst with new route reference and path mtu worked. But after the fix, the old routes started to get reused even after they were expired causing pmtu to break (well it would occationally work if the rtable gc had run recently and marked the route obsolete causing dst_check to get called).
