panic: acquiring blockable sleep lock with spinlock or critical section held (kernel_lock) &kernel_lock (7)

Status: fixed on 2023/01/12 22:01
Reported-by: syzbot+00a4824cb1b6a214c7d6@syzkaller.appspotmail.com
Fix commit: 9cf4e548dcbe Use solock() instead solock_shared() within sys_getsockopt(). Otherwise we acquiring kernel lock with mutex(9) held. This partially reverts rev 1.205 of sys/kern/uipc_syscalls.c. Shared solock() is still fine for getsockname(2) and getpeername(2).
