Subject: [PATCH] core: Fix edge case when processing /proc/self/mountinfo
|
|
|
9d460a |
|
|
|
9d460a |
Currently, if there are two /proc/self/mountinfo entries with the same
|
|
|
9d460a |
mount point path, the mount setup flags computed for the second of
|
|
|
9d460a |
these two entries will overwrite the mount setup flags computed for
|
|
|
9d460a |
the first of these two entries. This is the root cause of issue #7798.
|
|
|
9d460a |
This patch changes mount_setup_existing_unit to prevent the
|
|
|
9d460a |
just_mounted mount setup flag from being overwritten if it is set to
|
|
|
9d460a |
true. This will allow all mount units created from /proc/self/mountinfo
|
|
|
9d460a |
entries to be initialized properly.
