https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=295826 Bug ID: 295826 Summary: kern_renameat() infinite loop Product: Base System Version: 15.0-STABLE Hardware: Any OS: Any Status: New Severity: Affects Some People Priority: --- Component: kern Assignee: bugs@FreeBSD.org Reporter: rozhuk.im@gmail.com Target /usr/local/www dir was subject of multiple nullfs mount points. Looks like namei() got ERELOOKUP every time and can not exit loop. Probably some simple loop counter with some limit should fix this problem. # procstat kstack 80837 PID TID COMM TDNAME KSTACK 80837 487501 pkg-static - kern_renameat sys_renameat amd64_syscall fast_syscall_common 80837 487501 pkg-static -
