2010-07-21ixgbe/igb: catch invalid VF settingsAndy Gospodarek
Some ixgbe cards put an invalid VF device ID in the PCIe SR-IOV capability. The ixgbe driver is only valid for PFs or non SR-IOV hardware. It seems that the same problem could occur on igb hardware as well, so if we discover we are trying to initialize a VF in ixbge_probe or igb_probe, print an error and exit. Based on a patch for ixgbe from Chris Wright <chrisw@sous-sol.org>.

2010-07-21mac80211: proper IBSS lockingJohannes Berg
IBSS has never had locking, instead relying on some memory barriers etc. That's hard to get right, and I think we had it wrong too until the previous patch. Since this is not performance sensitive, it doesn't make sense to have the maintenance overhead of that, so add proper locking.

2010-07-21mac80211: fix IBSS lockdep complaintJohannes Berg
Bob reported a lockdep complaint originating in the mac80211 IBSS code due to the common work struct patch. The reason is that the IBSS and station mode code have different locking orders for the cfg80211 wdev lock and the work struct (where "locking" implies running/canceling). Fix this by simply not canceling the work in the IBSS code, it is not necessary since when the REQ_RUN bit is cleared, the work will run without effect if it runs. When the interface is set down, it is flushed anyway, so there's no concern about it running after memory has been invalidated either. This fixes https://bugzilla.kernel.org/show_bug.cgi?id=16419 Additionally, looking into this I noticed that there's a small window while the IBSS is torn down in which the work may be rescheduled and the REQ_RUN bit be set again after leave() has cleared it when a scan finishes at exactly the same time. Avoid that by setting the ssid_len to zero before clearing REQ_RUN which signals to the scan finish code that this interface is not active.

2010-07-21cfg80211: fix race between sysfs and cfg80211Maxime Bizon
device_add() is called before adding the phy to the cfg80211 device list. So if a userspace program uses sysfs uevents to detect new phy devices, and queries nl80211 to get phy info, it can get ENODEV even though the phy exists in sysfs. An easy workaround is to hold the cfg80211 mutex until the phy is present in sysfs/cfg80211/debugfs. Signed-off-by: Maxime Bizon <mbizon@freebox.fr> Signed-off-by: John W.
