nl80211: fix attrbuf access race by allocating a separate one

2013-06-19T16:31:20+00:00

Since my commit 3713b4e364 ("nl80211: allow splitting wiphy
information in dumps"), nl80211_dump_wiphy() uses the global
nl80211_fam.attrbuf for parsing the incoming data. This wouldn't
be a problem if it only did so on the first dump iteration which
is locked against other commands in generic netlink, but due to
space constraints in cb->args (the needed state doesn't fit) I
decided to always parse the original message. That's racy though
since nl80211_fam.attrbuf could be used by some other parsing in
generic netlink concurrently.

For now, fix this by allocating a separate parse buffer (it's a
bit too big for the stack, currently 1448 bytes on 64-bit). For
-next, I'll change the code to parse into the global buffer in
the first round only and then allocate a smaller buffer to keep
the data in cb->args.

cfg80211: fix reporting 64-bit station info tx bytes

2013-05-23T20:08:18+00:00

Copy & paste mistake - STATION_INFO_TX_BYTES64 is the name of the flag,
not NL80211_STA_INFO_TX_BYTES64.

cfg80211: check wdev->netdev in connection work

2013-05-23T16:12:38+00:00

If a P2P-Device is present and another virtual interface triggers
the connection work, the system crash because it tries to check
if the P2P-Device's netdev (which doesn't exist) is up. Skip any
wdevs that have no netdev to fix this.

cfg80211: fix sending WoWLAN TCP wakeup settings

2013-05-16T20:38:09+00:00

The code sending the current WoWLAN TCP wakeup settings in
nl80211_send_wowlan_tcp() is not closing the nested attribute,
thus causing the parser to get confused on the receiver side
in userspace (iw). Fix this.

cfg80211: fix interface down/disconnect state handling

2013-05-16T20:38:08+00:00

When the interface goes down, there's no need to call
cfg80211_mlme_down() after __cfg80211_disconnect() as
the latter will call the former (if appropriate.)

Also, in __cfg80211_disconnect(), if the cfg80211 SME
isn't used, __cfg80211_disconnected() may still need
to be called (depending on the current state) so that
the SME state gets cleared.

nl80211: Add wdev identifier to some nl80211 notifications

2013-05-16T20:38:06+00:00

Adding the attributes fixes an issue with P2P Device not
working properly for management frame TX.

cfg80211: fix WoWLAN wakeup tracing

2013-05-16T20:38:03+00:00

If the device reports a non-wireless wakeup reason, the
tracing code crashes trying to dereference a NULL pointer.
Fix this by checking the pointer on all accesses and also
add a non_wireless tag to the event.

cfg80211: fix wiphy_register error path

2013-05-16T20:38:02+00:00

If rfkill_register() fails in wiphy_register() the struct device
is unregistered but everything else isn't (regulatory, debugfs)
and we even leave the wiphy instance on all internal lists even
though it will likely be freed soon, which is clearly a problem.
Fix this by cleaning up properly.

2013-05-02T00:51:54+00:00

Pull VFS updates from Al Viro,

Misc cleanups all over the place, mainly wrt /proc interfaces (switch
create_proc_entry to proc_create(), get rid of the deprecated
create_proc_read_entry() in favor of using proc_create_data() and
seq_file etc).
