From 89fd2e282ad510f801c1f44a660086f9d5bdf088 Mon Sep 17 00:00:00 2001 From: Bob Copeland Date: Mon, 12 May 2008 21:16:44 -0400 Subject: ath5k: Fix loop variable initializations In ath5k_tasklet_rx, both status structures 'rxs' and 'rs' are initialized at the top of the tasklet, but not within the loop. If the loop is executed multiple times in the tasklet then the variables may see changes from previous packets. For TKIP, this results in 'Invalid Michael MIC' errors if two packets are processed in the tasklet: rxs.flag gets set to RX_DECRYPTED by mac80211 when it decrypts the first encrypted packet. The subsequent packet will have RX_DECRYPTED set upon entry to mac80211, so mac80211 will not try to decrypt it. We currently initialize all but two fields in the structures, so fix the other two.
