When freeing -the skb, it may not be really freed, since someone is still -holding a reference to it. -In that case, when TCP skb is being retransmitted, the -pointer to the frag list is being reused, while the data -in there is no longer valid. -Since we will never get frag list from the network stack, -as mac80211 doesn't advertise the capability, we can safely -free and nullify it before releasing the SKB. - -Signed-off-by: Sara Sharon <sara.sharon@intel.com> ---- - ---- a/net/mac80211/status.c -+++ b/net/mac80211/status.c -@@ -558,6 +558,11 @@ static void ieee80211_report_used_skb(st - } - - ieee80211_led_tx(local); -+ -+ if (skb_has_frag_list(skb)) { -+ kfree_skb_list(skb_shinfo(skb)->frag_list); -+ skb_shinfo(skb)->frag_list = NULL; -+ } - } - - /* |
