Pass struct rpc_request as the first argument instead of an untyped blob,
and mark the data object as const.

Declare the p_encode callbacks with the proper prototype instead of
casting to kxdreproc_t and losing all type safety.

just out of curiosity: you are talking about increasing type safety, but
at the same time replaces arguments to 'const void *data', which will accept
everything. Is there something special which I don't understand?

Nothing special - cast are potentially dangerous in general, and
function pointer cases are especially dangerous as there is no
verify the caller and callee signatures match at all. As generic
method call patterns need to have private data of some points they
need to have a void pointer somewhere - either in the signature or
as a pointer from a passed structure. For those the compiler at least
can do some basic sanity checking, and good static analysis tools can
even verify we get the proper object using whole program analysis.

Strong ACK on all of this.
I've been bitten before (in userland code) by having a function that
took 3 arguments cast to something that took 2. So the callers ends up
passing in too few arguments, and the function then just ends up using
junk out of a register or off the the stack to satisfy the missing one.
Not fun to track down.
Christoph, for the first 13 patches, you can add:

I'll look over the remaining ones later.

Also very much in favor of these patches.
Though I can't actually remembering seeing a bug here. So...

OK, that's good to know.
I'm more worried about the encoders and decoders themselves, but I don't
know what to do about them.

To: Trond Myklebust, Anna Schumaker, J. Bruce Fields, Jeff Layton; +Cc: linux-nfs
p_count is the only writeable memeber of struct rpc_procinfo, which is
a good candidate to be const-ified as it contains function pointers.
This patch just removes it and returns zero in the /proc file as the
count of calls per procedure doesn't seem all that useful. But it's
just a dumb hack and we might need a proper fix instead.

Drop the argp and resp arguments as they can trivially be derived from

and we can remove the unsafe casting to svc_procfunc as well as the
svc_procfunc typedef itself.

To: Trond Myklebust, Anna Schumaker, J. Bruce Fields, Jeff Layton; +Cc: linux-nfs
Drop the p and resp arguments as they are always NULL or can trivially
be derived from the rqstp argument. With that all functions now have the
same prototype, and we can remove the unsafe casting to kxdrproc_t.

To: Trond Myklebust, Anna Schumaker, J. Bruce Fields, Jeff Layton; +Cc: linux-nfs
Drop the argp argument as it can trivially be derived from the rqstp
argument. With that all functions now have the same prototype, and we
can remove the unsafe casting to kxdrproc_t.

To: Trond Myklebust, Anna Schumaker, J. Bruce Fields, Jeff Layton; +Cc: linux-nfs
Drop the resp argument as it can trivially be derived from the rqstp
argument. With that all functions now have the same prototype, and we
can remove the unsafe casting to kxdrproc_t.

From: Christoph Hellwig @ 2017-05-09 9:20 UTC (permalink / raw)
To: Trond Myklebust, Anna Schumaker, J. Bruce Fields, Jeff Layton; +Cc: linux-nfs
Pass union nfsd4_op_u to the op_func callbacks instead of using unsafe
function pointer casts.
It also adds two missing structures to struct nfsd4_op.u to facilitate
this.

pc_count is the only writeable memeber of struct svc_procinfo, which is
a good candidate to be const-ified as it contains function pointers.
This patch just removes it and returns zero in the /proc file as the
count of calls per procedure doesn't seem all that useful. But it's
just a dumb hack and we might need a proper fix instead.

The rest of the patches also look fine, aside from this one where I
agree with Trond and Chuck that we don't want to break nfsstat.

struct svc_procinfo contains function pointers, and marking it as
constant avoids it being able to be used as an attach vector for
code injections.
