From 2739a6845031e69be7c03461a9335d8bbb9f59bd Mon Sep 17 00:00:00 2001 From: Ed Maste Date: Wed, 31 Jul 2024 20:04:46 -0400 Subject: [PATCH] sshd: remove blacklist call from grace_alarm_timer Under certain circumstances it may call log(3), which is not async- signal-safe. For now just remove the blacklist integration from this path, which means that blacklistd will not detect and firewall hosts that establish a connection but do nothing further.
