Hello Jason, Couple of issues to report. I am running the wireguard-kmod-0.0.20210428 snapshot on my pfsense router. I am working with the pfSense-pkg-Wireguard effort in building the WG package. Admittedly I am mostly testing and providing some UI code. However I have come across 2 errors. First one is a KP that happened sometime today. db:0:kdb.enter.default> bt Tracing pid 0 tid 100402 td 0xfffff800c67b6740 kdb_enter() at kdb_enter+0x37/frame 0xfffffe004d02c4b0 vpanic() at vpanic+0x197/frame 0xfffffe004d02c500 panic() at panic+0x43/frame 0xfffffe004d02c560 trap_fatal() at trap_fatal+0x391/frame 0xfffffe004d02c5c0 trap() at trap+0x67/frame 0xfffffe004d02c6d0 calltrap() at calltrap+0x8/frame 0xfffffe004d02c6d0 --- trap 0x9, rip = 0xffffffff840fd580, rsp = 0xfffffe004d02c7a0, rbp = 0xfffffe004d02c7e0 --- noise_remote_index_insert() at noise_remote_index_insert+0xb0/frame 0xfffffe004d02c7e0 noise_consume_initiation() at noise_consume_initiation+0x6bb/frame 0xfffffe004d02ca10 wg_softc_handshake_receive() at wg_softc_handshake_receive+0x27a/frame 0xfffffe004d02cb20 gtaskqueue_run_locked() at gtaskqueue_run_locked+0x121/frame 0xfffffe004d02cb80 gtaskqueue_thread_loop() at gtaskqueue_thread_loop+0xb6/frame 0xfffffe004d02cbb0 fork_exit() at fork_exit+0x7e/frame 0xfffffe004d02cbf0 fork_trampoline() at fork_trampoline+0xe/frame 0xfffffe004d02cbf0 Second issue is that I am seeing memory silent corruption where the pfSense UI stops responding and serves up invalid files. Reboot fixes it. I have NOT noticed this issue with the 0415 snapshot; this happened both in the 0424 and 0428 snapshots. While I cannot definitively say its wg related, that is the only bit changing on the boxes. Thanks
