nl80211: Fix potential memory leak in nl80211_set_wowlan

2015-12-15T12:10:05+00:00

Compared to cfg80211_rdev_free_wowlan in core.h,
the error goto label lacks the freeing of nd_config.
Fix that.

nl80211: fix a few memory leaks in reg.c

2015-12-15T12:08:02+00:00

The first leak occurs when entering the default case
in the switch for the initiator in set_regdom.
The second leaks a platform_device struct if the
platform registration in regulatory_init succeeds but
the sub sequent regulatory hint fails due to no memory.

cfg80211: allow AID/listen interval changes for unassociated station

2015-11-03T10:20:29+00:00

Currently, cfg80211 rejects updates of AID and listen interval parameters
for existing entries. This information is known only at association stage
and as a result it's impossible to update entries that were added
unassociated.
Fix this by allowing updates of these properies for stations that the
driver (or mac80211) assigned unassociated state.

This then fixes mac80211's use of NL80211_FEATURE_FULL_AP_CLIENT_STATE.

nl80211: Fix potential memory leak from parse_acl_data

2015-11-03T09:40:58+00:00

If parse_acl_data succeeds but the subsequent parsing of smps
attributes fails, there will be a memory leak due to early returns.
Fix that by moving the ACL parsing later.

cfg80211: reg: fix reg_ignore_cell_hint return type

The return type should be enum reg_request_treatment for both
branches of the #ifdef.

cfg80211: reg: reduce chan_reg_rule_print_dbg() ifdef

2015-10-16T07:15:45+00:00

The function is void and static, so just ifdef its contents
instead of duplicating the declaration.

cfg80211: reg: fix antenna gain in chan_reg_rule_print_dbg()

2015-10-16T07:15:44+00:00

Printing "N/A mBi" is strange - print just "N/A" instead.

Also add a missing opening parenthesis.

cfg80211: reg: centralize freeing ignored requests

2015-10-16T07:15:44+00:00

Instead of having a lot of places that free ignored requests
and then return REG_REQ_OK, make reg_process_hint() process
REG_REQ_IGNORE by freeing the request, and let functions it
calls return that instead of freeing.

This also fixes a leak when a second (different) country IE
hint was ignored.

cfg80211: reg: clarify 'treatment' handling in reg_process_hint()

2015-10-16T07:15:44+00:00

This function can only deal with treatment values OK and ALREADY_SET
so make the callees not return anything else and warn if they do.
