Subject: Bug/misfeature of "securityfs"
I write a module which creates a securityfs on init
foobar = securityfs_create_dir("foobar", NULL)
and on exit it does
security_fs_remove(foobar);
When I do "insmod" and "rmmod", I see
/sys/kernel/security/foobar/
appear and go away.
Now, if have a shell and do "cd /sys/kernel/security/foobar", the
"rmmod" does not remove the directory. The directory disappears when I
exit the shell from it via "cd ..". This is fine, and as it should be,
but....
IF, while having the shell in the directory, I try to "insmod" again,
the insmod fails with "-1 File exists". Again, understandable, BUT
when after this I exit the shell from the directory, IT DOES NOT GO
AWAY. It's permanetly existing, and module install fails always with
"File Exists".
Is this a bug, or am doing something wrong?
The kernel is Ubuntu Hardy heron
