Hello, On kernel 3.13, I was able to disable the transmission retries on the wlan0 interface with 'iwconfig wlan0 retry 0'. Now I updated my kernel to 3.16, and it returns with 'Invalid argument' error. The cause is this commit: cfg80211: add sanity check for retry limit in wext-compat http://git.kernel.org/cgit/linux/kernel/git/torvalds/linux.git/commit/?id=f5aa0d21dd5ada040ff42b4d40357285e4ace441 --- a/net/wireless/wext-compat.c +++ b/net/wireless/wext-compat.c @@ -370,7 +370,7 @@ static int cfg80211_wext_siwretry(struct net_device *dev, u8 oshort = wdev->wiphy->retry_short; int err; - if (retry->disabled || + if (retry->disabled || retry->value < 1 || retry->value > 255 || (retry->flags & IW_RETRY_TYPE) != IW_RETRY_LIMIT) return -EINVAL; I'm wondering, is the 'retry->value < 1' is necessary? I would write 'retry->value < 0' instead, to make possible to disable the retries. Should I send a patch? Thanks!
