rS305785: net80211: improve error checking in ieee80211_parse_{wpa,rsn}()
Summary
  • Add few checks for group/pairwise ciphers in ieee80211_parse_{wpa,rsn}.
  • Split error code and cipher value in wpa_cipher() / rsn_cipher(); current hack with (1 << 32) does not work - it's 1, not 0 (originally detected by CSA).
  • Return IEEE80211_REASON_UNSUPP_RSN_IE_VERSION instead of IEEE80211_REASON_IE_INVALID when version field is not equal to RSN_VERSION.
Test Plan

Tested with wpi(4) / urtwn(4); no visible regressions.
