wext: handle NULL extra data in iwe_stream_add_point better

2017-11-02T06:16:20Z

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.

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

wext: Emit event stream entries correctly when compat.

2008-06-17T01:50:49Z

Three major portions to this change: 1) Add IW_EV_COMPAT_LCP_LEN, IW_EV_COMPAT_POINT_OFF, and IW_EV_COMPAT_POINT_LEN helper defines. 2) Delete iw_stream_check_add_*(), they are unused. 3) Add iw_request_info argument to iwe_stream_add_*(), and use it to size the event and pointer lengths correctly depending upon whether IW_REQUEST_FLAG_COMPAT is set or not. 4) The mechanical transformations to the drivers and wireless stack bits to get the iw_request_info passed down into the routines modified in #3. Also, explicit references to IW_EV_LCP_LEN are replaced with iwe_stream_lcp_len(info). With a lot of help and bug fixes from Masakazu Mokuno. Signed-off-by: David S. Miller
