Some drivers unfortunately cannot support software crypto, but mac80211 currently assumes that they do. This has the issue that if the hardware enabling fails for some reason, the software fallback is used, which won't work. This clearly isn't desirable, the error should be reported and the key setting refused. Support this in mac80211 by allowing drivers to set a new HW flag IEEE80211_HW_SW_CRYPTO_CONTROL, in which case mac80211 will only allow software fallback if the set_key() method returns 1. The driver will also need to advertise supported cipher suites so that mac80211 doesn't advertise any (future) software ciphers that the driver can't actually do. While at it, to make it easier to support this, refactor the ieee80211_init_cipher_suites() code. Signed-off-by: Johannes Berg <johannes.berg@intel.com> |
