From 1ac62ba7c985109868a18d959986425148481f47 Mon Sep 17 00:00:00 2001 From: Ben Hutchings Date: Sun, 1 Aug 2010 17:37:03 +0100 Subject: mac80211: Don't squash error codes in key setup functions ieee80211_add_key() currently returns -ENOMEM in case of any error, including a missing crypto algorithm. Change ieee80211_key_alloc() and ieee80211_aes_{key_setup_encrypt,cmac_key_setup}() to encode errors with ERR_PTR() rather than returning NULL, and change ieee80211_add_key() accordingly. Compile-tested only. Reported-by: Marcin Owsiany Signed-off-by: Ben Hutchings Acked-by: Johannes Berg Signed-off-by: John W.
