Subject: [REVIEW][PATCH 0/15] userns subsystem conversions
This patchset updates all of the major linux subsystems that use uids
and gids to store them in kuid_t and kgid_t types.
This update allows some of the subsystems to work in all user namespaces
while other subsystems were updated to only work in the initial user
namespace.
kuid_t and kgid_t values have been pushed as deeply into the code as
possible to allow type checking to find as many problems as possible.
In a couple of cases this involved taking an implicit union stored in
an unsigned int and making it an explicit union.
This patchset is based on 3.6-rc1 and strictly against:
git.kernel.org/pub/scm/linux/kernel/git/ebiederm/user-namespace.git for-next
My intention after these patches have been reviewed is to add them to my
non-rebasing for-next branch of my user namespace tree and to merge
these changes into 3.7.
I had hoped when I converted the core kernel that I would have removed
the interactions between subsystems and would be able to merge these
changes independently through maintainer trees in a timely fashion, but
there are just enough dependencies and interactions that the changes
really all need to be in one tree to make these changes testable/usable.
Once these changes hit my for-next branch I won't be rebasing them so
if a maintainer wants to merge them to avoid conflicts feel free.
The biggest cross subystem change this round is probably the change
to have audit_get_loginuid return a kuid_t, but it certainly isn't
the only cross subsystem change.
Eric W. Biederman (15):
userns: Enable building of pf_key sockets when user namespace support is enabled.
userns: Make credential debugging user namespace safe.
userns: Convert security/keys to the new userns infrastructure
userns: net: Call key_alloc with GLOBAL_ROOT_UID, GLOBAL_ROOT_GID instead of 0, 0
userns: Convert ipc to use kuid and kgid where appropriate
userns: Convert audit to use kuid and kgid where appropriate
userns: Convert taskstats to handle the user and pid namespaces.
userns: Convert bsd process accounting to use kuid and kgid where appropriate
userns: Convert process event connector to handle kuids and kgids
userns: Convert debugfs to use kuid/kgid where appropriate.
userns: Teach trace to use from_kuid
userns: Convert drm to use kuid and kgid and struct pid where appropriate
userns: Add basic quota support
userns: Convert vfs posix_acl support to use kuid and kgid where appripriate.
userns: Convert configfs to use kuid and kgid where appropriate
