commit ac266e2edc4f40eef810d52c72657b645e4010db
Author: Ondrej Mosnacek <omosnace@redhat.com>
Date: Tue Apr 6 15:57:37 2021 -0400
exportfs: fix unexporting of '/'
The code that has been added to strip trailing slashes from path in
unexportfs_parsed() forgot to account for the case of the root
directory, which is simply '/'. In that case it accesses path[-1] and
reduces the path to an empty string, which then fails to match any
export.
Fix it by stopping the stripping when the path is just a single
character - it doesn't matter if it's a '/' or not, we want to keep it
either way in that case.
Reproducer:
exportfs localhost:/
exportfs -u localhost:/
Without this patch, the unexport step fails with "exportfs: Could not
find 'localhost:/' to unexport."
Fixes: a9a7728d8743 ("exportfs: Deal with path's trailing "/" in unexportfs_parsed()")
