wext: handle NULL extra data in iwe_stream_add_point better

2017-08-11T15:49:34Z

commit 93be2b74279c15c2844684b1a027fdc71dd5d9bf upstream. gcc-7 complains that wl3501_cs passes NULL into a function that then uses the argument as the input for memcpy: drivers/net/wireless/wl3501_cs.c: In function 'wl3501_get_scan': include/net/iw_handler.h:559:3: error: argument 2 null where non-null expected [-Werror=nonnull] memcpy(stream + point_len, extra, iwe->u.data.length); This works fine here because iwe->u.data.length is guaranteed to be 0 and the memcpy doesn't actually have an effect. Making the length check explicit avoids the warning and should have no other effect here. Also check the pointer itself, since otherwise we get warnings elsewhere in the code.

cfg80211/wext: fix message ordering

2016-01-29T16:13:43Z

Since cfg80211 frequently takes actions from its netdev notifier call, wireless extensions messages could still be ordered badly since the wext netdev notifier, since wext is built into the kernel, runs before the cfg80211 netdev notifier. For example, the following can happen: 5: wlan1: mtu 1500 qdisc mq state DOWN group default link/ether 02:00:00:00:01:00 brd ff:ff:ff:ff:ff:ff 5: wlan1: link/ether when setting the interface down causes the wext message. To also fix this, export the wireless_nlevent_flush() function and also call it from the cfg80211 notifier. Cc: stable@vger.kernel.org Signed-off-by: Johannes Berg

wext: add checked wrappers for adding events/points to streams

2015-02-28T20:31:12Z

These checked wrappers are necessary for the next patch, which will use them to avoid sending out partial scan results. Signed-off-by: Johannes Berg

iw_handler.h: Remove extern from function prototypes

2013-09-21T18:01:39Z

There are a mix of function prototypes with and without extern in the kernel sources. Standardize on not using extern for function prototypes. Function prototypes don't need to be written with extern. extern is assumed by the compiler. Its use is as unnecessary as using auto to declare automatic/local variables in a block.

wext: refactor

2009-10-07T20:39:43Z

Refactor wext to * split out iwpriv handling * split out iwspy handling * split out procfs support * allow cfg80211 to have wireless extensions compat code w/o CONFIG_WIRELESS_EXT After this, drivers need to - select WIRELESS_EXT - for wext support - select WEXT_PRIV - for iwpriv support - select WEXT_SPY - for iwspy support except cfg80211 -- which gets new hooks in wext-core.c and can then get wext handlers without CONFIG_WIRELESS_EXT. Wireless extensions procfs support is auto-selected based on PROC_FS and anything that requires the wext core (i.e. WIRELESS_EXT or CFG80211_WEXT). Signed-off-by: Johannes Berg Signed-off-by: John W.

libipw: switch from ieee80211_* to libipw_* naming policy

2009-08-28T18:40:28Z

This eliminates the dual definition of ieee80211_channel (and possibly others), further clarifying who defines what and paving the way for inclusion of cfg80211.h. Signed-off-by: John W. Linville
