SUNRPC refactor rpcauth_checkverf error returns

2013-09-03T19:25:09+00:00

Most of the time an error from the credops crvalidate function means the
server has sent us a garbage verifier. The gss_validate function is the
exception where there is an -EACCES case if the user GSS_context on the client
has expired.

SUNRPC: Replace clnt->cl_principal

2013-08-30T13:19:36+00:00

The clnt->cl_principal is being used exclusively to store the service
target name for RPCSEC_GSS/krb5 callbacks. Replace it with something that
is stored only in the RPCSEC_GSS-specific code.

sunrpc: Properly encode kuids and kgids in RPC_AUTH_UNIX credentials

2013-02-13T14:15:24+00:00

When writing kuids onto the wire first map them into the initial user
namespace.

When writing kgids onto the wire first map them into the initial user
namespace.

sunrpc: Use gid_valid to test for gid != INVALID_GID

2013-02-13T14:15:20+00:00

In auth unix there are a couple of places INVALID_GID is used a
sentinel to mark the end of uc_gids array.  Use gid_valid
as a type safe way to verify we have not hit the end of
valid data in the array.

sunrpc: Convert kuids and kgids to uids and gids for printing

2013-02-13T14:15:19+00:00

When printing kuids and kgids for debugging purpropses convert them
to ordinary integers so their values can be fed to the oridnary
print functions.

sunrpc: Simplify auth_unix now that everything is a kgid_t

2013-02-13T14:15:18+00:00

In unx_create_cred directly assign gids from acred->group_info
to cred->uc_gids.

In unx_match directly compare uc_gids with group_info.

Now that both group_info and unx_cred gids are stored as kgids
this is valid and the extra layer of translation can be removed.

sunrpc: Use uid_eq and gid_eq where appropriate

2013-02-13T14:15:17+00:00

When comparing uids use uid_eq instead of ==.
When comparing gids use gid_eq instead of ==.

And unfortunate cost of type safety.

sunrpc: Use kuid_t and kgid_t where appropriate

2013-02-13T14:15:16+00:00

Convert variables that store uids and gids to be of type
kuid_t and kgid_t instead of type uid_t and gid_t.

sunrpc: Use userns friendly constants.

2013-02-13T14:15:15+00:00

Instead of (uid_t)0 use GLOBAL_ROOT_UID.
Instead of (gid_t)0 use GLOBAL_ROOT_GID.
Instead of (uid_t)-1 use INVALID_UID
Instead of (gid_t)-1 use INVALID_GID.
Instead of NOGROUP use INVALID_GID.

userns: Convert group_info values from gid_t to kgid_t.

2012-05-03T10:27:21+00:00

As a first step to converting struct cred to be all kuid_t and kgid_t
values convert the group values stored in group_info to always be
kgid_t values.   Unless user namespaces are used this change should
have no effect.
