[PATCH v1 01/15] SUNRPC: Missing module alias for auth_rpcgss.ko

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Commit f344f6df "SUNRPC: Auto-load RPC authentication kernel
modules", Mon Mar 20 13:44:08 2006, adds a request_module() call
in rpcauth_create() to auto-load RPC security modules when a ULP
tries to create a credential of that flavor.

In rpcauth_create(), the name of the module to load is built like
this:

	request_module("rpc-auth-%u", flavor);

This means that for, say, RPC_AUTH_GSS, request_module() is looking
for a module or alias called "rpc-auth-6".

The GSS module is named "auth_rpcgss", and commit f344f6df does not
add any new module aliases.  There is also no such alias provided in
/etc/modprobe.d on my system (Fedora 16).  Without this alias, the
GSS module is not loaded on demand.

This is used by rpcauth_create().  The pseudoflavor_to_flavor() call
can return RPC_AUTH_GSS, which is passed to request_module().
