We expose this parameter for a future caller.
It will be used to extract the endtime from the gss-proxy upcall mechanism,
in order to set the rsc cache expiration time.

The gss_mech_list_pseudoflavors() function provides a list of
currently registered GSS pseudoflavors. This list does not include
any non-GSS flavors that have been registered with the RPC client.
nfs4_find_root_sec() currently adds these extra flavors by hand.
Instead, nfs4_find_root_sec() should be looking at the set of flavors
that have been explicitly registered via rpcauth_register(). And,
other areas of code will soon need the same kind of list that
contains all flavors the kernel currently knows about (see below).
Rather than cloning the open-coded logic in nfs4_find_root_sec() to
those new places, introduce a generic RPC function that generates a
full list of registered auth flavors and pseudoflavors.
A new rpc_authops method is added that lists a flavor's
pseudoflavors, if it has any. I encountered an interesting module
loader loop when I tried to get the RPC client to invoke
gss_mech_list_pseudoflavors() by name.
This patch is a pre-requisite for server trunking discovery, and a
pre-requisite for fixing up the in-kernel mount client to do better
automatic security flavor selection.

When sec=<something> is not presented as a mount option,
we should attempt to determine what security flavor the
server is using.

Again, we can deadlock if the memory reclaim triggers a writeback that
requires a rpcsec_gss credential lookup.

The text based upcall now indicates which Kerberos encryption types are
supported by the kernel rpcsecgss code. This is used by gssd to
determine which encryption types it should attempt to negotiate
when creating a context with a server.
The server principal's database and keytab encryption types are
what limits what it should negotiate. Therefore, its keytab
should be created with only the enctypes listed by this file.
Currently we support des-cbc-crc, des-cbc-md4 and des-cbc-md5

Not only are the qop parameters that are passed around throughout the gssapi
unused by any currently implemented mechanism, but there appears to be some

Initial git repository build. I'm not bothering with the full history,
even though we have it. We can create a separate "historical" git
archive of that later if we want to, and in the meantime it's about
3.2GB when imported into git - space that would just make the early
git days unnecessarily complicated, when we don't have a lot of good
infrastructure for it.
Let it rip!
