802.1Q expanded the maximum ethernet frame size by 4 bytes for the VLAN tag. We're not taking this into account in virtio_net, which means the buffers we provide to the backend in the virtqueue RX ring aren't big enough to hold a full MTU VLAN packet. For QEMU/KVM, this results in the backend exiting with a packet truncation error. Signed-off-by:

There is a race between sctp_rcv() and sctp_accept() where we have moved the association from the listening socket to the accepted socket, but sctp_rcv() processing cached the old socket and continues to use it. The easy solution is to check for the socket mismatch once we've grabed the socket lock. If we hit a mis-match, that means that were are currently holding the lock on the listening socket, but the association is refrencing a newly accepted socket. We need to drop the lock on the old socket and grab the lock on the new one. A more proper solution might be to create accepted sockets when the new association is established, similar to TCP. That would eliminate the race for 1-to-1 style sockets, but it would still existing for 1-to-many sockets where a user wished to peeloff an association. For now, we'll live with this easy solution as it addresses the problem. Reported-by:

Recent changes to the retransmit code exposed a long standing bug where it was possible for a chunk to be time stamped after the retransmit timer was reset. This caused a rare situation where the retrnamist timer has expired, but nothing was marked for retrnasmission because all of timesamps on data were less then 1 rto ago. As result, the timer was never restarted since nothing was retransmitted, and this resulted in a hung association that did couldn't complete the data transfer. The solution is to timestamp the chunk when it's added to the packet for transmission purposes. After the packet is trsnmitted the rtx timer is restarted. This guarantees that when the timer expires, there will be data to retransmit. Signed-off-by:

Commit 62aeaff5 (sctp: Start T3-RTX timer when fast retransmitting lowest TSN) introduced a regression where it was possible to forcibly restart the sctp retransmit timer at the transmission of any new chunk. This resulted in much longer timeout times and sometimes hung sctp connections. Signed-off-by:

crc32c algorithm provides a byteswaped result. On little-endian arches, the result ends up in big-endian/network byte order. On big-endinan arches, the result ends up in little-endian order and needs to be byte swapped again. Thus calling cpu_to_le32 gives the right output. Tested-by:

Suspend/resume routines check for phydrv != NULL, but that is wrong because "phydrv" comes from container_of(drv). If drv is NULL, then container_of(drv) will return non-NULL result, and the checks won't work. The Freescale TBI PHYs are driver-less, so "drv" is NULL, and that leads to the following oops: Unable to handle kernel paging request for data at address 0xffffffe4 Faulting instruction address: 0xc0215554 Oops: Kernel access of bad area, sig: 11 [#1] [...] NIP [c0215554] mdio_bus_suspend+0x34/0x70 LR [c01cc508] suspend_device+0x258/0x2bc Call Trace: [cfad3da0] [cfad3db8] 0xcfad3db8 (unreliable) [cfad3db0] [c01cc508] suspend_device+0x258/0x2bc [cfad3dd0] [c01cc62c] dpm_suspend+0xc0/0x140 [cfad3e20] [c01cc6f4] device_suspend+0x48/0x5c [cfad3e40] [c0068dd8] suspend_devices_and_enter+0x8c/0x148 [cfad3e60] [c00690f8] enter_state+0x100/0x118 [cfad3e80] [c00691c0] state_store+0xb0/0xe4 [cfad3ea0] [c018c938] kobj_attr_store+0x24/0x3c [cfad3eb0] [c00ea9a8] flush_write_buffer+0x58/0x7c [cfad3ed0] [c00eadf0] sysfs_write_file+0x58/0xa0 [cfad3ef0] [c009e810] vfs_write+0xb4/0x16c [cfad3f10] [c009ed40] sys_write+0x4c/0x90 [cfad3f40] [c0014954] ret_from_syscall+0x0/0x38 [...] This patch fixes the issue, plus removes unneeded parentheses and fixes indentation level in mdio_bus_suspend().

A link change interrupt might be queued and activated after the loopback was set and it will cause the loopback to fail. The PHY lock should be kept until the loopback test is over. That implies that the bnx2x_test_link should used within the loopback function and not bnx2x_wait_for_link since that function also takes the PHY link Signed-off-by:

Mac80211 provides 2 structures to handle bitrates, namely ieee80211_rate and ieee80211_tx_rate. To determine the short preamble mode for an outgoing frame, the flag IEEE80211_TX_RC_USE_SHORT_PREAMBLE must be checked on ieee80211_tx_rate and not ieee80211_rate (which rt2x00 did). This fixes a regression which was triggered in 2.6.29-rcX as reported by Chris Clayton. Signed-off-by:

The previous fix to paged packets broke the merging because it reset the skb->len before we added it to the merged packet. This wasn't detected because it simply resulted in the truncation of the packet while the missing bit is subsequently retransmitted. The fix is to store skb->len before we clobber it. Signed-off-by:

Roel Kluin reported a bug in two error paths where skbs were wrongly being freed using kfree(). He provided a fix where it was replaced to kfree_skb(), as it should be. However, in i2400mu_rx(), the error path was missing returning an indication of the failure. Changed to reset rx_skb to NULL and return it to the caller, i2400mu_rxd(). It will be treated as a transient error and just ignore the packet. Depending on the buffering conditions inside the device, the data packet might be dropped or the device will signal the host again for data-ready-to-read and the host will retry. Signed-off-by:

Contrary to what the docs say, the 'extended interrupt cause' bit in the interrupt cause register (bit 1) appears to not be maskable on at least some of the mv643xx_eth platforms, making writing zeroes to the interrupt mask register but not the extended interrupt mask register insufficient to stop interrupts from occuring. Therefore, also write zeroes to the extended interrupt mask register when shutting down the port. This fixes the interrupt storm seen on the Pegasos board when shutting down the interface.
