Bug ID: 213859
Summary: /dev/pf device busy causes issues in complex systems
Product: Base System
Version: 10.0-RELEASE
Hardware: amd64
OS: Any
Status: New
Severity: Affects Some People
Priority: ---
Component: kern
Assignee: freebsd-bugs@FreeBSD.org
Reporter: jja...@gmail.com

Probably filed under pf:
I have firewall systems using pf, with ftp_proxy as well. Under certain
circumstances, relayd will crash when updating a table if something else (such
as ftp_proxy, tftp_proxy, or a local rules edit) has /dev/pf locked.
I've seen other cases, where an individual ftp_proxy will also fail, if
something else grabbed /dev/pf as well -- and seeing "pfctl: DIOCADDRULE:
Device busy " failures when doing manual updates is quite common.
relayd logs attached:
