Lennart Poettering 08c849815c label: rework label_fix() implementations (#8583 ) This reworks the SELinux and SMACK label fixing calls in a number of ways: 1. The two separate boolean arguments of these functions are converted into a flags type LabelFixFlags. 2. The operations are now implemented based on O_PATH. This should resolve TTOCTTOU races between determining the label for the file system object and applying it, as it it allows to pin the object while we are operating on it. 3. When changing a label fails we'll query the label previously set, and if matches what we want to set anyway we'll suppress the error. Also, all calls to label_fix() are now (void)ified, when we ignore the return values. Fixes: #8566	2018-03-27 07:38:26 +02:00

Lennart Poettering 08c849815c label: rework label_fix() implementations (#8583 )

This reworks the SELinux and SMACK label fixing calls in a number of
ways:

1. The two separate boolean arguments of these functions are converted
   into a flags type LabelFixFlags.

2. The operations are now implemented based on O_PATH. This should
   resolve TTOCTTOU races between determining the label for the file
   system object and applying it, as it it allows to pin the object
   while we are operating on it.

3. When changing a label fails we'll query the label previously set, and
   if matches what we want to set anyway we'll suppress the error.

Also, all calls to label_fix() are now (void)ified, when we ignore the
return values.

Fixes: #8566
