Zeeb <bz@FreeBSD.org> changed: What |Removed |Added ---------------------------------------------------------------------------- Status|New |Open CC| |markj@FreeBSD.org --- Comment #2 from Bjoern A. Zeeb <bz@FreeBSD.org> --- Do you have IEEE80211_DEBUG enabled? Also, if you have src+obj code, can you lookup and verify my assuptions based on main w/o kasan in kernel: ieee80211_crypto_ccmp.c:669 ff: 68 #1 0xffffffff81580899 at ccmp_encap+0xe99 (memcpy or debug error after?) 193 #2 0xffffffff815808df at ccmp_encap+0xedf (also around the memcpy, stats?) ieee80211_crypto_ccmp.c:299: 62 #1 0xffffffff81580953 at ccmp_encap+0xf53 (m_adj?) I am just curious as the distribution later is quite wide, which indeed seems to indicate that the data buffer at that point isn't valid. 25 #1 0xffffffff80599a6c at rijndaelEncrypt+0x25c 25 #1 0xffffffff80599af7 at rijndaelEncrypt+0x2e7 25 #1 0xffffffff80599b7c at rijndaelEncrypt+0x36c 24 #1 0xffffffff80599c01 at rijndaelEncrypt+0x3f1 26 #1 0xffffffff80599ca5 at rijndaelEncrypt+0x495 27 #1 0xffffffff80599d2c at rijndaelEncrypt+0x51c 21 #1 0xffffffff80599db1 at rijndaelEncrypt+0x5a1 20 #1 0xffffffff80599e36 at rijndaelEncrypt+0x626 Strangely the ccmp code has not seen functional changes in years. -- You are receiving this mail because: You are the assignee for the bug.
