net: Add export.h for EXPORT_SYMBOL/THIS_MODULE to non-modules

2011-10-31T23:30:30+00:00

These files are non modular, but need to export symbols using
the macros now living in export.h -- call out the include so
that things won't break when we remove the implicit presence
of module.h from everywhere.

net: add moduleparam.h for users of module_param/MODULE_PARM_DESC

2011-10-31T23:30:29+00:00

These files were getting access to these two via the implicit
presence of module.h everywhere.  They aren't modules, so they
don't need the full module.h inclusion though.

wireless: Reset beacon_found while updating regulatory

2011-09-16T19:32:08+00:00

During the association, the regulatory is updated by country IE
that reaps the previously found beacons. The impact is that
after a STA disconnects *or* when for any reason a regulatory
domain change happens the beacon hint flag is not cleared
therefore preventing future beacon hints to be learned.
This is important as a regulatory domain change or a restore
of regulatory settings would set back the passive scan and no-ibss
flags on the channel. This is the right place to do this given that
it covers any regulatory domain change.

cfg80211: hold reg_mutex when updating regulatory

2011-09-14T17:26:39+00:00

The function wiphy_update_regulatory() uses the static variable
last_request and thus needs to be called with reg_mutex held.
This is the case for all users in reg.c, but the function was
exported for use by wiphy_register(), from where it is called
without the lock being held.

Fix this by making wiphy_update_regulatory() private and introducing
regulatory_update() as a wrapper that acquires and holds the lock.

cfg80211: print bandwidth in chan_reg_rule_print_dbg()

2011-09-13T19:53:46+00:00

Two spaces and the second "KHz" suggest that the code author meant to
print the bandwidth but forgot it.  The code appears in commit e702d3cf
already with two spaces and "KHz" in place of the bandwidth.

cfg80211: really ignore the regulatory request

2011-07-26T20:27:29+00:00

At the beginning of wiphy_update_regulatory() a check is performed
whether the request is to be ignored. Then the request is sent to
the driver nevertheless. This happens even if last_request points
to NULL, leading to a crash in the driver:

 [] (lbs_set_11d_domain_info+0x28/0x1e4 [libertas]) from [] (wiphy_update_regulatory+0x4d0/0x4f4)
 [] (wiphy_update_regulatory+0x4d0/0x4f4) from [] (wiphy_register+0x354/0x420)
 [] (wiphy_register+0x354/0x420) from [] (lbs_cfg_register+0x80/0x164 [libertas])
 [] (lbs_cfg_register+0x80/0x164 [libertas]) from [] (lbs_start_card+0x20/0x88 [libertas])
 [] (lbs_start_card+0x20/0x88 [libertas]) from [] (if_sdio_probe+0x898/0x9c0 [libertas_sdio])

Fix this by returning early. Also remove the out: label as it is
not any longer needed.
