- compile eapol_test binary to allow testing via radius proxy and server (note: this does not match CONFIG_EAPOL_TEST which sets -Werror and activates an assert call inside the code of wpa_supplicant) (bsc#1111873), (fate#326725)o - add patch to fix wrong operator precedence in ieee802_11.c wpa_supplicant-git-fa67debf4c6ddbc881a212b175faa6d5d0d90c8c.patch - add patch to avoid redefinition of __bitwise macro wpa_supplicant-git-f5b74b966c942feb95a8ddbb7d130540b15b796d.patch OBS-URL: https://build.opensuse.org/request/show/642093 OBS-URL: https://build.opensuse.org/package/show/hardware/wpa_supplicant?expand=0&rev=87

Fix duplicate Reassociation Request frame dropping
|
|
|
|
Relational operators (==) have higher precedence than the ternary
|
|
conditional in C. The last_subtype check for association/reassociation
|
|
was broken due to incorrect assumption about the precedence. Fix this by
|
|
adding parenthesis around the ternary conditional.
|
|
|
|
The previous implementation worked for Association Request frames by
|
|
accident since WLAN_FC_STYPE_ASSOC_REQ happens to have value 0 and when
|
|
the last receive frame was an Association Request frame, the
|
|
sta->last_subtype == reassoc check was true and non-zero
|
|
WLAN_FC_STYPE_REASSOC_REQ was interpreted as true. However, this was
|
|
broken for Reassociation Request frame. reassoc == 1 in that case could
|
|
have matched received Association Response frame (subtype == 1), but
|
|
those are not received in AP mode and as such, this did not break other
|
|
behavior apart from not being able to drop duplicated Reassociation
|
|
Request frames.
