mac80211: disable powersave for broken APs

2011-11-11T17:44:44+00:00

commit 05cb91085760ca378f28fc274fbf77fc4fd9886c upstream.

Only AID values 1-2007 are valid, but some APs have been
found to send random bogus values, in the reported case an
AP that was sending the AID field value 0xffff, an AID of
0x3fff (16383).

There isn't much we can do but disable powersave since
there's no way it can work properly in this case.

mac80211: config hw when going back on-channel

2011-11-11T17:44:44+00:00

commit 6911bf0453e0d6ea8eb694a4ce67a68d071c538e upstream.

When going back on-channel, we should reconfigure
the hw iff the hardware is not already configured
to the operational channel.

mac80211: fix remain_off_channel regression

2011-11-11T17:44:44+00:00

commit eaa7af2ae582c9a8c51b374c48d5970b748a5ce2 upstream.

The offchannel code is currently broken - we should
remain_off_channel if the work was started, and
the work's channel and channel_type are the same
as local->tmp_channel and local->tmp_channel_type.

However, if wk->chan_type and local->tmp_channel_type
coexist (e.g. have the same channel type), we won't
remain_off_channel.

This behavior was introduced by commit da2fd1f
("mac80211: Allow work items to use existing
channel type.")

NFS/sunrpc: don't use a credential with extra groups.

2011-11-11T17:44:30+00:00

commit dc6f55e9f8dac4b6479be67c5c9128ad37bb491f upstream.

The sunrpc layer keeps a cache of recently used credentials and
'unx_match' is used to find the credential which matches the current
process.

However unx_match allows a match when the cached credential has extra
groups at the end of uc_gids list which are not in the process group list.

So if a process with a list of (say) 4 group accesses a file and gains
access because of the last group in the list, then another process
with the same uid and gid, and a gid list being the first tree of the
gids of the original process tries to access the file, it will be
granted access even though it shouldn't as the wrong rpc credential
will be used.

ipv6: fix route error binding peer in func icmp6_dst_alloc

2011-11-11T17:43:39+00:00

[ Upstream commit 7011687f0f2f12cc348f6a693fafe63d89167eac ]

in func icmp6_dst_alloc,dst_metric_set call ipv6_cow_metrics to set metric.
ipv6_cow_metrics may will call rt6_bind_peer to set rt6_info->rt6i_peer.
So,we should move ipv6_addr_copy before dst_metric_set to make sure rt6_bind_peer success.

net: hold sock reference while processing tx timestamps

2011-11-11T17:43:08+00:00

commit da92b194cc36b5dc1fbd85206aeeffd80bee0c39 upstream.

The pair of functions,

 * skb_clone_tx_timestamp()
 * skb_complete_tx_timestamp()

were designed to allow timestamping in PHY devices. The first
function, called during the MAC driver's hard_xmit method, identifies
PTP protocol packets, clones them, and gives them to the PHY device
driver. The PHY driver may hold onto the packet and deliver it at a
later time using the second function, which adds the packet to the
socket's error queue.

As pointed out by Johannes, nothing prevents the socket from
disappearing while the cloned packet is sitting in the PHY driver
awaiting a timestamp. This patch fixes the issue by taking a reference
on the socket for each such packet. In addition, the comments
regarding the usage of these function are expanded to highlight the
rule that PHY drivers must use skb_complete_tx_timestamp() to release
the packet, in order to release the socket reference, too.

These functions first appeared in v2.6.36.

mac80211: fix offchannel TX cookie matching

commit 28a1bcdb57d50f3038a255741ecc83e391e5282e upstream.

When I introduced in-kernel off-channel TX I
introduced a bug -- the work can't be canceled
again because the code clear the skb pointer.
Fix this by keeping track separately of whether
TX status has already been reported.

rtnetlink: Add missing manual netlink notification in dev_change_net_namespaces

2011-11-11T17:43:05+00:00

commit d2237d35748e7f448a9c2d9dc6a85ef637466e24 upstream.

Renato Westphal noticed that since commit a2835763e130c343ace5320c20d33c281e7097b7
"rtnetlink: handle rtnl_link netlink notifications manually" was merged
we no longer send a netlink message when a networking device is moved
from one network namespace to another.

Fix this by adding the missing manual notification in dev_change_net_namespaces.

Since all network devices that are processed by dev_change_net_namspaces are
in the initialized state the complicated tests that guard the manual
rtmsg_ifinfo calls in rollback_registered and register_netdevice are
unnecessary and we can just perform a plain notification.
