Hi.
selinux.restorecon(path, recursive=True) uses matchpathcon() to get a
label for a file and when the label is defined as <<None>>,it throws a
backtrace with error:
"OSError: [Errno 2] No such file or directory"
It creates a problem for scripts which tries to relabel whole directory tree
when there a subdirectory with a specification like this:
/var/lib/nfs/rpc_pipefs(/.*)? all files <<None>>
>>> selinux.restorecon('/var/lib', recursive=True)
Traceback (most recent call last):
File "/usr/lib64/python3.5/site-packages/selinux/__init__.py", line 114, in restorecon
status, context = matchpathcon(path, mode)
FileNotFoundError: [Errno 2] No such file or directory
At the same time, there's a rfe to rewrite restorecon() to use
selinux_restorecon() which uses selabel_lookup() instead of deprecated
matchpathcon() - [1]
The following 2 patches tries to address the described problem using the RFE.
First patch exports selinux_restorecon() to SWIG bindings.
Second one rewites python implementation of restorecon() to use it.
