Originally published at: Hotfix Release Of Pi-hole v4.2.2 – Pi-hole
We released two small updates to Core and FTL, which will bump both to version 4.2.2.
In the Core codebase, some users experienced crashes if their systems were without
libcap support which caused FTLDNS to run as
root, later dropping to the unprivileged user
pihole. As the shared memory objects used for FTLDNS are created before this switch, issues such as failing to access, reallocate, or delete the shared memory were seen. For most of you, this update will be transparent.
Meanwhile, the release of FTLDNS will let FTLDNS continue running as
root if necessary on the given system. This will let FTLDNS retain access to its shared memory. We’ve added one related feature that reports both the user
pihole-FTL started as and the user
pihole-FTL crashed as in case it crashes and generated a crash ticket in
Also included, is a fix for the blocking status display for
NXDOMAIN blocking modes, which were incorrectly reported as
OK (cached) although they were blocking just fine by FTL v4.2.
Finally, there is a fix that also fixes FTL crashing by adjusting the
overTime data structure.
Thanks for reporting these issues and help us making Pi-hole a better software!
