2012-01-12phylib: introduce mdiobus_alloc_size()Timur Tabi
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: Timur Tabi <timur@freescale.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2012-01-12net: decrement memcg jump label when limit, not usage, is changedGlauber Costa
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 a9b3cd7f32 (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: Eric Dumazet <eric.dumazet@gmail.com> CC: Stephen Hemminger <shemminger@vyatta.com> CC: Paul E.

2012-01-11mac80211: fix rx->key NULL pointer dereference in promiscuous modeStanislaw Gruszka
Since: commit 816c04fe7ef01dd9649f5ccfe796474db8708be5 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).

2012-01-11nl80211: fix old station flags compatibilityJohannes Berg
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.

2012-01-10ath9k: Fix regression in channelwidth switch at the same channelRajkumar Manoharan
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.

2012-01-09dcache: use a dispose list in select_parentDave Chinner
select_parent currently abuses the dentry cache LRU to provide cleanup features for child dentries that need to be freed. It moves them to the tail of the LRU, then tells shrink_dcache_parent() to calls __shrink_dcache_sb to unconditionally move them to a dispose list (as DCACHE_REFERENCED is ignored). __shrink_dcache_sb() has to relock the dentries to move them off the LRU onto the dispose list, but otherwise does not touch the dentries that select_parent() moved to the tail of the LRU. It then passses the dispose list to shrink_dentry_list() which tries to free the dentries. IOWs, the use of __shrink_dcache_sb() is superfluous - we can build exactly the same list of dentries for disposal directly in select_parent() and call shrink_dentry_list() instead of calling __shrink_dcache_sb() to do that. This means that we avoid long holds on the lru lock walking the LRU moving dentries to the dispose list We also avoid the need to relock each dentry just to move it off the LRU, reducing the numebr of times we lock each dentry to dispose of them in shrink_dcache_parent() from 3 to 2 times. Further, we remove one of the two callers of __shrink_dcache_sb(). This also means that __shrink_dcache_sb can be moved into back into prune_dcache_sb() and we no longer have to handle referenced dentries conditionally, simplifying the code.
