cfg80211: disable CSA for all drivers

2013-12-02T10:53:44+00:00

The channel switch announcement code has some major locking problems
which can cause a deadlock in worst case. A series of fixes has been
proposed, but these are non-trivial and need to be tested first.
Therefore disable CSA completely for 3.13.

cfg80211: disable 5/10 MHz support for all drivers

2013-11-25T15:50:11+00:00

Due to nl80211 API breakage, 5/10 MHz support is broken for
all drivers. Fixing it requires adding new API, but that
can't be done as a bugfix commit since that would require
either updating all APIs in the trees needing the bugfix or
cause different kernels to have incompatible API.

Therefore, just disable 5/10 MHz support for all drivers.

nl80211: check nla_nest_start() return value

2013-11-25T15:50:07+00:00

Coverity pointed out that we might dereference NULL later
if nla_nest_start() returns a failure. This isn't really
true since we'd bomb out before, but we should check the
return value directly, so do that.

nl80211: fix error path in nl80211_get_key()

2013-11-25T15:50:06+00:00

Coverity pointed out that in the (practically impossible)
error case we leak the message - fix this.

nl80211: check nla_put_* return values

2013-11-25T15:50:05+00:00

Coverity pointed out that in a few functions we don't
check the return value of the nla_put_*() calls. Most
of these are fairly harmless because the input isn't
very dynamic and controlled by the kernel, but the
pattern is simply wrong, so fix this.

cfg80211: fix ibss wext chandef creation

2013-11-25T15:50:02+00:00

The wext internal chandefs for ibss should be created using the
cfg80211_chandef_create() functions. Initializing fields manually is
error-prone.

genetlink: make multicast groups const, prevent abuse

2013-11-19T21:39:06+00:00

Register generic netlink multicast groups as an array with
the family and give them contiguous group IDs. Then instead
of passing the global group ID to the various functions that
send messages, pass the ID relative to the family - for most
families that's just 0 because the only have one group.

This avoids the list_head and ID in each group, adding a new
field for the mcast group ID offset to the family.

At the same time, this allows us to prevent abusing groups
again like the quota and dropmon code did, since we can now
check that a family only uses a group it owns.

genetlink: pass family to functions using groups

2013-11-19T21:39:06+00:00

This doesn't really change anything, but prepares for the
next patch that will change the APIs to pass the group ID
within the family, rather than the global group ID.

genetlink: only pass array to genl_register_family_with_ops()

2013-11-19T21:39:05+00:00

As suggested by David Miller, make genl_register_family_with_ops()
a macro and pass only the array, evaluating ARRAY_SIZE() in the
macro, this is a little safer.

The openvswitch has some indirection, assing ops/n_ops directly in
that code. This might ultimately just assign the pointers in the
family initializations, saving the struct genl_family_and_ops and
code (once mcast groups are handled differently.)
