Subject: [pve-devel] [PATCH] Check only first part of script parameter for executability
Date: Thu, 21 Oct 2021 10:46:50 +0200	[thread overview]
Message-ID: <20211021084650.26753-1-pr@lima-city.de> (raw)

When giving a script parameter including arguments to the dump process,
the full script parameter including the arguments is checked for
executablility. The following will always abort with a "not executable"
error:

vzdump 100 --script "/usr/local/bin/myscript.pl myarg"

If we split the script argument and check only the first part, the
check works as expected.
