Hello All!
There are problems with some IPC objects:
1. FIFO.
a) RSBAC create FIFO file as T_FILE target (see do_mknod() );
b) While opening FIFO RSBAC see it as T_IPC ( see filp_open() and
open_namei() ) and get wrong ACI information as a result.
c) rsbac_get_attr_n() function doesn't allow to see any FIFO's
attributes (Only for Regular, Block and Character Devices)
2. AF_UNIX sockets
a) sys_rsbac_set_attr and sys_rsbac_get_attr work with socket using
virtual inode.
b) While open socket ( open_namei() ) RSBAC see ordinal inode (not
virtual), and apply wrong sock structure (wrong ACI) as a result.
Note: virtual inode's value you can see in proc (ls -al /proc/1266/fd/*)
real inode you can see using stat (stat ~/my_socket).
Any solutions?

With best regards
Stanislav Ievlev.
