Imho: longest path match wins.
can you show your fcontext rules regarding that directory?
tip: with `matchpathcon /path/...` you can try any path what context it
would get (existing or not (yet) existing paths) without changing
anything on the fs.
Ah, thanks. Did that, and the /<path>/smwa/webagent/bin is bin_t. Now,
that might be right... but the idiots of CA, who only know Windows, do
not
have a ./lib, and all the .so's are in the bin directory... Am I going to
have to live with that?
Fully specified pathnames (i.e. no regexes) win. But locally-added file
contexts entries should take precedence over system-provided ones anyway
IIRC. What does setfiles -d
/etc/selinux/targeted/contexts/files/file_contexts
/<path>/smwa/webagent/bin/foo.so report? Note by the way that your
regex only matches things that end in .so, so /path/smwa/webagent/bin
itself wouldn't match. Also note that you should escape the dot (\.so)
if you want it literally and not the regex match-any character.
What is in that <path> prefix might make a difference. Anyway, the
following contrived example seemed to work correctly (on Fedora):
# mkdir -p /opt/foo/bin
# touch /opt/foo/bin/libc.so
# restorecon -rv /opt/foo
Relabeled /opt/foo/bin from unconfined_u:object_r:usr_t:s0 to
unconfined_u:object_r:bin_t:s0
Relabeled /opt/foo/bin/libc.so from unconfined_u:object_r:usr_t:s0 to
unconfined_u:object_r:bin_t:s0
# semanage fcontext -a -t lib_t "/opt/foo/bin/.*\.so(\.[0-9]+)*"
# touch /opt/foo/bin/libc.so.9
# touch /opt/foo/bin/libc.so.1.0.3
# restorecon -Rv /opt/foo
Relabeled /opt/foo/bin/libc.so.9 from unconfined_u:object_r:bin_t:s0 to
unconfined_u:object_r:lib_t:s0
Relabeled /opt/foo/bin/libc.so.1.0.3 from unconfined_u:object_r:bin_t:s0
to unconfined_u:object_r:lib_t:s0
Relabeled /opt/foo/bin/libc.so from unconfined_u:object_r:bin_t:s0 to
unconfined_u:object_r:lib_t:s0

semanage fcontext ...
Duh... Yeah, a few minutes after I posted, I realized that, and it
*seemed* to work. But now, I've got a different issue: I did a
restorecon -rv /*/smwa/webagent/bin... and now all the .so's are bin_t,
instead of lib_t

We're forced to use Siteminder, by CA, who have no clue what
they're doing in *nix. No packages, tarballs...
Anyway, I'm trying clean up some stuff, and in /*/smwa/webagent/bin
(all
their binaries, including .so's, are in there, duh... I'm trying to
set
the .so's to lib_t. semanage -fcontext -a -t lib_t
"/<elided>/smwa/webagent/bin(/.*).so"
gives me the completely unexpected response of semanage: error:
argument
subcommand: invalid choice: 'lib_t' (choose
from 'import', 'export', 'login', 'user', 'port', 'ibpkey',
'ibendport',
'interface', 'module', 'node', 'fcontext', 'boolean', 'permissive',

What am I doing wrong?
