Subject: Re: [PATCH][LSM] Early init for security modules 1/4
Reply-To:
In-Reply-To: <[email protected]>; from [email protected] on Fri, Jun 13, 2003 at 12:04:09AM -0700
[LSM] early init for security modules. As discussed before, this allows
for early initialization of security modules when compiled statically
into the kernel. The standard do_initcalls is too late for complete
coverage of all filesystems and threads, for example.

[LSM] Remove task_kmod_set_label hook, it is no longer necessary.
kmod is now handled by keventd which already does reparent_to_init,
so there is no need to worry about getting the security labels right
for code running off the keventd workqueue.

Patch from Jakub Jel?nek <[email protected]>
[LSM] make sure setfsuid/setfsgid return values are right. Before
include/linux/security.h was added, setfsuid/setfsgid always returned
old_fsuid, no matter if the fsuid was actually changed or not. With
the default security ops it seems to do the same, because both
security_task_setuid and security_task_post_setuid return 0, but
these are hooks which seem to return 0 on success, -errno on failure,
so if some non-default security hook is installed and ever returns
-errno in setfsuid/setfsgid, -errno will be returned from the syscall
instead of the expected old_fsuid. This makes it hard to distinguish
uids 0xfffff001 .. 0xffffffff from errors of security hooks.

argh, sorry about the blank subject on that first patch. typing too
quickly.
