Bug ID: 217651
Summary: devfs: adding an improper ruleset, e.g. one that has
improperly quoted globs, are hard to delete
Product: Base System
Version: CURRENT
Hardware: Any
OS: Any
Status: New
Severity: Affects Some People
Priority: ---
Component: kern
Assignee: [email protected]
Reporter: [email protected]
Repro:
Run the following commands as root:
1. Add a bogus ruleset with improperly quoted paths for "/dev/pass*" and
"/dev/xpt*" (change 20/21 to another ruleset that's not currently taken):
# cat >> /etc/devfs.rules <<'EOF'
[devfsrules_modify_perms_for_wheel=20]
add path pass* mode 660 group wheel
add path xpt* mode 660 group wheel
[devfsrules_modify_perms_for_wheel=21]
add path "pass*" mode 660 group wheel
add path "xpt*" mode 660 group wheel
EOF
2. Run /etc/rc.d/devfs, e.g., "service devfs start".
3. Verify that the ruleset has been added:
# devfs rule showsets | egrep '^2[01]$'
20
21
#
4. Try deleting the newly added rulesets, e.g.,
# devfs rule -s 20 delset
# devfs rule -s 21 delset
5. Verify that they've been deleted by rerunning the command in 3.
Expected results:
Both rulesets should be deleted.
Actual results:
Ruleset 20 remains:
# devfs rule showsets | egrep '^2[01]$'
20
