Subject: [PATCH] ima: Install on filesystems without xattr support without
|
||
|
|
failing
|
||
|
|
|
||
|
|
If an RPM contains IMA signed digests and rpm-plugin-ima is installed,
|
||
|
|
then any attempt to install to a filesystem that doesn't support
|
||
|
|
extended attributes will cause the RPM installation to fail.
|
||
|
|
|
||
|
|
This can be seen, for example, if installing a file /boot, which is
|
||
|
|
usually a vFAT filesystem.
|
||
|
|
|
||
|
|
The rpm-plugin for selinux fixed this some time back, and that same
|
||
|
|
logic can be applied to IMA too - where, if a failure to set an extended
|
||
|
|
attribute results in an errno that is set to EOPNOTSUPP, then this
|
||
|
|
should not cause a complete failure, but should instead just be logged
|
||
|
|
at a debug level.
