From 1df2bdba528b5a7a30f1b107b6924aa79af5e00e Mon Sep 17 00:00:00 2001 From: Mathy Vanhoef Date: Thu, 23 Jul 2020 14:01:48 +0400 Subject: [PATCH] mac80211: never drop injected frames even if normally not allowed In ieee80211_tx_dequeue there is a check to see if the dequeued frame is allowed in the current state. Injected frames that are normally not allowed are being be dropped here. Fix this by checking if a frame was injected and if so always allowing it.
