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: 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()

2015-10-16T07:15:43+00:00

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.

cfg80211: reg: search built-in database directly

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

Instead of searching the built-in database only in the worker,
search it directly and return an error if the entry cannot be
found (or memory cannot be allocated.) This means that builtin
database queries no longer rely on the timeout.
