this is most likely identical to crash you've reported ?two weeks ago?
I can not find an email with it.
I'm working on diff to get it fixed. Will try to finish it later
today.
according to stack and registers we die at line 1196 in pf_state_export() due
to NULL pointer dereference:
0xffffffff8172ee58 is in pf_state_export
(/home/sashan/src.sashan/sys/net/pf.c:1196).
1191 int32_t expire;
1192
1193 memset(sp, 0, sizeof(struct pfsync_state));
1194
1195 /* copy from state key */
1196 sp->key[PF_SK_WIRE].addr[0] = st->key[PF_SK_WIRE]->addr[0];
1197 sp->key[PF_SK_WIRE].addr[1] = st->key[PF_SK_WIRE]->addr[1];
1198 sp->key[PF_SK_WIRE].port[0] = st->key[PF_SK_WIRE]->port[0];
1199 sp->key[PF_SK_WIRE].port[1] = st->key[PF_SK_WIRE]->port[1];
1200 sp->key[PF_SK_WIRE].rdomain = htons(st->key[PF_SK_WIRE]->rdomain
