selinux: log anon inode class name
Log the anonymous inode class name in the security hook inode_init_security_anon. This name is the key for name based type transitions on the anon_inode security class on creation. Example: type=AVC msg=audit(02/16/22 22:02:50.585:216) : avc: granted \ { create } for pid=2136 comm=mariadbd anonclass=[io_uring] \ scontext=system_u:system_r:mysqld_t:s0 \ tcontext=system_u:system_r:mysqld_iouring_t:s0 tclass=anon_inode Add a new LSM audit data type holding the inode and the class name. Signed-off-by: Christian Göttsche <cgzones@googlemail.com> [PM: adjusted 'anonclass' to be a trusted string, cgzones approved] Signed-off-by: Paul Moore <paul@paul-moore.com>
