selinux: fix memory leak in sel_make_bools
In sel_make_bools, kernel allocates memory for bool_pending_names[i] with security_get_bools. So if we just free bool_pending_names, those memories for bool_pending_names[i] will be leaked. This patch resolves dozens of following kmemleak report after resuming from suspend: unreferenced object 0xffff88022e4c7380 (size 32): comm "init", pid 1, jiffies 4294677173 backtrace: [<ffffffff810f76b5>] create_object+0x1a2/0x2a9 [<ffffffff810f78bb>] kmemleak_alloc+0x26/0x4b [<ffffffff810ef3eb>] __kmalloc+0x18f/0x1b8 [<ffffffff811cd511>] security_get_bools+0xd7/0x16f [<ffffffff811c48c0>] sel_write_load+0x12e/0x62b [<ffffffff810f9a39>] vfs_write+0xae/0x10b [<ffffffff810f9b56>] sys_write+0x4a/0x6e [<ffffffff81011b82>] system_call_fastpath+0x16/0x1b [<ffffffffffffffff>] 0xffffffffffffffff Signed-off-by: Xiaotian Feng <dfeng@redhat.com> Signed-off-by: James Morris <jmorris@namei.org>
