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

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

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.

cfg80211: reg: rename reg_regdb_query() to reg_query_builtin()

The new name better reflects the functionality.

cfg80211: reg: make CRDA support optional

2015-10-16T07:15:39+00:00

If there's a built-in regulatory database, there may be little point
in also calling out to CRDA and failing if the system is configured
that way. Allow removing CRDA support to save ~1K kernel size.

cfg80211: reg: remove useless reg_timeout scheduling

2015-10-15T14:17:09+00:00

When the functions reg_set_rd_driver() and reg_set_rd_country_ie()
return with an error, the calling function already restores data
by calling restore_regulatory_settings(), so there's no need to
also schedule a timeout (which would lead to other side effects
such as indicating CRDA failed, which clearly isn't true.) Remove
the scheduling.
