Subject: [PATCH 20/83] Revert "mdadm: fix coredump of mdadm --monitor -r"
|
2022-11-15 06:54:39 +00:00
|
|
|
|
|
|
|
|
This reverts commit 546047688e1c64638f462147c755b58119cabdc8.
|
|
|
|
|
|
|
|
|
|
The change from commit mdadm: fix coredump of mdadm
|
|
|
|
|
--monitor -r broke the printing of the return message when
|
|
|
|
|
passing -r to mdadm --manage, the removal of a device from
|
|
|
|
|
an array.
|
|
|
|
|
|
|
|
|
|
If the current code reverts this commit, both issues are
|
|
|
|
|
still fixed.
|
|
|
|
|
|
|
|
|
|
The original problem reported that the fix tried to address
|
|
|
|
|
was: The --monitor -r option requires a parameter,
|
|
|
|
|
otherwise a null pointer will be manipulated when
|
|
|
|
|
converting to integer data, and a core dump will appear.
|
|
|
|
|
|
|
|
|
|
The original problem was really fixed with:
|
|
|
|
|
60815698c0a Refactor parse_num and use it to parse optarg.
|
|
|
|
|
Which added a check for NULL in 'optarg' before moving it
|
|
|
|
|
to the 'increments' variable.
|
|
|
|
|
|
|
|
|
|
New issue: When trying to remove a device using the short
|
|
|
|
|
argument -r, instead of the long argument --remove, the
|
|
|
|
|
output is empty. The problem started when commit
|
|
|
|
|
546047688e1c was added.
|
|
|
|
|
|
|
|
|
|
Steps to Reproduce:
|
|
|
|
|
1. create/assemble /dev/md0 device
|
|
|
|
|
2. mdadm --manage /dev/md0 -r /dev/vdxx
|
|
|
|
|
|
|
|
|
|
Actual results:
|
|
|
|
|
Nothing, empty output, nothing happens, the device is still
|
|
|
|
|
connected to the array.
|
|
|
|
|
|
|
|
|
|
The output should have stated "mdadm: hot remove failed
|
|
|
|
|
for /dev/vdxx: Device or resource busy", if the device was
|
|
|
|
|
still active. Or it should remove the device and print
|
|
|
|
|
a message:
|
|
|
|
|
|
|
|
|
|
mdadm: set /dev/vdd faulty in /dev/md0
|
|
|
|
|
mdadm: hot removed /dev/vdd from /dev/md0
|
|
|
|
|
|
|
|
|
|
The following commit should be reverted as it breaks
|
|
|
|
|
mdadm --manage -r.
|
