sendmmsg uses a similar error return strategy as recvmmsg but it turns out to be a confusing way to communicate errors. The current code stores the error code away and returns it on the next sendmmsg call. This means a call with completely valid arguments could get an error from a previous call. Change things so we only return an error if no datagrams could be sent. If less than the requested number of messages were sent, the application must retry starting at the first failed one and if the problem is persistent the error will be returned. This matches the behaviour of other syscalls like read/write - it is not an error if less than the requested number of elements are sent. Signed-off-by:

When TX underrun occurs, a cleanup is performed that marks all buffers as used. As a side effect it also clears the wrap bit in the last buffer. This patch will restore the wrap bit. Signed-off-by:

Fix a misusage of the struct usb_cdc_notification to pass arguments to the usb_control_msg function. The usb_control_msg function expects host endian arguments but usb_cdc_notification stores these values as little endian. Now usb_control_msg is directly invoked with host endian values.

Gergely Kalman reported crashes in check_peer_redir(). It appears commit f39925db (ipv4: Cache learned redirect information in inetpeer.) added a race, leading to possible NULL ptr dereference. Since we can now change dst neighbour, we should make sure a reader can safely use a neighbour. Add RCU protection to dst neighbour, and make sure check_peer_redir() can be called safely by different cpus in parallel. As neighbours are already freed after one RCU grace period, this patch should not add typical RCU penalty (cache cold effects) Many thanks to Gergely for providing a pretty report pointing to the bug.

Tx queues were stopped before bp->state was changed to a value different from BNX2X_STATE_OPEN, which allowed the bnx2x_tx_int() called from the NAPI context to re-enable it. This then allowed the netdev->ndo_start_xmit() to be called in the middle of the function reset and rings freeing. This patch changes bp->state to a value different from BNX2X_STATE_OPEN BEFORE disabling the Tx queues in order to restore the broken protection against the above race in the bnx2x_tx_int().

This driver uses information from the self member of the pci_bus struct to get information regarding the bridge to which the PCIe device is attached. Unfortunately, this member is not established on all architectures, which leads to a kernel oops. Skipping the entire block that uses the self member to determine the bridge vendor will only affect RTL8192DE devices as that driver sets the ASPM support flag differently when the bridge vendor is Intel. If the self member is available, there is no functional change. This patch fixes Bugzilla No. 40212. Reported-by:

We receive many bug reports about system hang during suspend/resume when ath9k driver is in use. Adrian Chadd remarked that this problem happens on systems that have ASPM disabled. To do not hit the bug, skip doing ->config_pci_powersave magic if PCIe downstream port device, which ath9k device is connected to, has ASPM disabled. Bug was introduced by: commit 53bc7aa0 Author: Vivek Natarajan <vnatarajan@atheros.com> Date: Mon Apr 5 14:48:04 2010 +0530 ath9k: Add support for newer AR9285 chipsets.
