Bash Version: 5.0
Patch Level: 2
Release Status: release
Description:
Since patch bash50-001 there is a regession on path expansion.
The script example below shows:
bash/bash> bash tmp/bug.sh
5.0.2(1)-release
drwxr-xr-x 2 nobody root 17 Mar 4 14:08 .
bash/bash> /dist/unpacked/sle15-x86_64.full/bin/bash tmp/bug.sh
4.4.23(1)-release
-rw-r--r-- 1 nobody root 0 Mar 4 14:10
/tmp/bugthroughpatch001/hidden/foo/bar
Disabling patch bash50-001 solves this problem but cause
other problems. It seems as seen by strace and ltrace that
the bash with patch bash50-001 now makes a stat(2) on every
single part of the path and run onto EACCES error which cause
the regression above.
Repeat-By:
<script>
#!/bin/bash -x
sudo mkdir -p /tmp/bugthroughpatch001/hidden/foo
sudo touch /tmp/bugthroughpatch001/hidden/foo/bar
sudo chown nobody -R /tmp/bugthroughpatch001
sudo chmod 711 /tmp/bugthroughpatch001/hidden
shopt -s nullglob
SRCDIR=/tmp/bugthroughpatch001/hidden/foo
cd "$SRCDIR"
MYSRCDIR="$SRCDIR"
echo $BASH_VERSION
ls -ld "$MYSRCDIR"/*
<script/>
Fix:
No working fix known (onyl disabling patch bash50-001)
