On FreeBSD 11 the nightly replace works fine. On FreeBSD 12.0-RELEASE-p3 (and on the latest HardenedBSD 12-STABLE) update= of the pf table fails with the following message "pfctl: Invalid argument." On further inspection, pfctl does not anymore allow to replace a table with more than 32768 (2^15) IP addresses. Flushing and adding works fine, just replacing leads to the error. How to reproduce Download list of 32769 badhosts to /tmp/pf-badhost.txt: https://gist.github.com/utrenkner/617534545407587a8919dc6b47676f6e Add this line to pf.conf: table persist file "/tmp/pf-badhost.txt" Load new rules: pfctl -f /etc/pf.conf Verify that table has 32769 entries: pfctl -t pfbadhost -T show | wc -l Now, try to replace table: pfctl -t pfbadhost -T replace -f /tmp/pf-badhost.txt This will fail. Remove one IP address from /tmp/pf-badhost.txt and try replacing table again: pfctl -t pfbadhost -T replace -f /tmp/pf-badhost.txt Result: "1 addresses deleted." I can -T flush and -T add, but it seems a bug to me that -T replace does not work with the same number of IP addresses. --=20 You are receiving this mail because: You are the assignee for the bug.=
