When TX time stamping for PTP messages is enabled on a socket, a time stamp is returned on the socket error queue to the user space application after the frame was transmitted. The transmitted frame is also returned on the error queue so that an application knows to which frame the time stamp belongs. In the current implementation the TxFCB is immediately followed by the frame. Since the eTSEC inserts the TX time stamp 8 bytes after the TxFCB, parts of the frame have been overwritten and an invalid frame was returned on the socket error queue. This patch fixes the described problem by adding additional 16 padding bytes between the TxFCB and the frame for all messages sent from a time stamping enabled socket (other sockets are not affected).

When there is not enough headroom in the skb a private copy will be made. However, the private copy had no reference to the socket and consequently no time stamp could be queued on the socket error queue during the skb_tstamp_tx function. This patch fixes this issue by also stealing the sock reference from the original skb after making the private copy. Signed-off-by:

Introduce function mdiobus_alloc_size() as an alternative to mdiobus_alloc(). Most callers of mdiobus_alloc() also allocate a private data structure, and then manually point bus->priv to this object. mdiobus_alloc_size() combines the two operations into one, which simplifies memory management. The original mdiobus_alloc() now just calls mdiobus_alloc_size(0). Signed-off-by:

The logic of the current code is that whenever we destroy a cgroup that had its limit set (set meaning different than maximum), we should decrement the jump_label counter. Otherwise we assume it was never incremented. But what the code actually does is test for RES_USAGE instead of RES_LIMIT. Usage being different than maximum is likely to be true most of the time. The effect of this is that the key must become negative, and since the jump_label test says: !!atomic_read(&key->enabled); we'll have jump_labels still on when no one else is using this functionality.

commit a9b3cd7f (rcu: convert uses of rcu_assign_pointer(x, NULL) to RCU_INIT_POINTER) did a lot of incorrect changes, since it did a complete conversion of rcu_assign_pointer(x, y) to RCU_INIT_POINTER(x, y). We miss needed barriers, even on x86, when y is not NULL. Signed-off-by:

Since: commit 816c04fe Author: Christian Lamparter <chunkeey@googlemail.com> Date: Sat Apr 30 15:24:30 2011 +0200 mac80211: consolidate MIC failure report handling is possible to that we dereference rx->key == NULL when driver set RX_FLAG_MMIC_STRIPPED and not RX_FLAG_IV_STRIPPED and we are in promiscuous mode. This happen with rt73usb and rt61pci at least. Before the commit we always check rx->key against NULL, so I assume fix should be done in mac80211 (also mic_fail path has similar check).

My patch to validate station flags broke compatibility with the old station flags setting where all flags are always set at once since it always set the mask as all possible flags which ended up being rejected later in the station add/modify code. Fix by parsing only the current flags in the old flags attribute -- new applications and new flags should use (and will now require) the new flags attribute where the mask is given by the application.

In kernel v3.2 initialization sequence for Asix 88178 devices was changed so that hardware is reseted on every time interface is brought up (ifconfig up), instead just at USB probe time. This causes problem with setting custom MAC address to device as ax88178_reset causes reload of MAC address from EEPROM. This patch fixes the issue by rewriting MAC address at end of ax88178_reset.

The commit "ath9k: Fix invalid noisefloor reading due to channel update" preserves the current channel noisefloor readings before updating channel type at the same channel index. It is also updating the curchan pointer. As survey updation is also referring curchan pointer to fetch the appropriate index, which might leads to invalid memory access. This patch partially reverts the change and stores the noise floor history buffer before updating channel type w/o updating curchan.
