[debian-mysql] Bug#975911: mariadb-client: appears to ignore ~/.editrc keybind settings

[Trevor Cordes]

I confirmed I was correct by making a small patch to libedit and
recompiling libedit and installing the custom rpm.  It indeed fixes
this bug, without any changes to mysql.  The bug is for sure in
libedit.  The bug is for sure the issetugid-related code.

My patch to libedit-20210419-3.1.tar.gz is attached.

Note: this patch is almost certainly a security hole as I don't address
the reason that setuid stuff is in there in the first place.  Consider
it a PoC and not something you should use unless you know what you are
doing.  I would expect the upstream to come up with a real fix shortly.
