https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=3D208140 Kristof Provost <kp@freebsd.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |kp@freebsd.org --- Comment #4 from Kristof Provost <kp@freebsd.org> --- Could you show the contents of (*state)->key[PF_SK_WIRE (0)] and (*state)->key[PF_SK_STACK (1)] at the time of the panic? I'm more interested in the state of the pf_state, because the pf_desc is allocated on the stack in the calling function. It's very unlikely to be a = bad pointer here. My current hypothesis is that you're unlucky enough to have one core in pf_test_state_udp() trying to use state->key[] while another core is in pf_state_key_attach().=20 The locking there is rather complicated, so before I dig into that it'd be = nice to confirm that one of the PF_SK_WIRE or PF_SK_STACK keys is NULL. (I'd exp= ect PF_SK_STACK to be NULL, in fact.) --=20 You are receiving this mail because: You are on the CC list for the bug.=
