It's harmless to set this after the server is created, but also
ineffective, since the value is only used at the time of
svc_create_pooled(). So fail the attempt, in keeping with the pattern
set by write_versions, write_{lease,grace}time and write_recoverydir.
(This could break userspace that tried to write to nfsd/max_block_size
between setting up sockets and starting the server. However, such code
wouldn't have worked anyway, and I don't know of any examples--rpc.nfsd
in nfs-utils, probably the only user of the interface, doesn't do that.)
Signed-off-by: J. Bruce Fields <bfields@redhat.com>
Commit 59db4a0c10 "nfsd: move more into
nfsd_startup()" inadvertently moved nfsd_versions after
nfsd_create_svc(). On older distributions using an rpc.nfsd that does
not explicitly set the list of nfsd versions, this results in
svc-create_pooled() being called with an empty versions array. The
resulting incomplete initialization leads to a NULL dereference in
svc_process_common() the first time a client accesses the server.
Move nfsd_reset_versions() back before the svc_create_pooled(); this
time, put it closer to the svc_create_pooled() call, to make this
mistake more difficult in the future.

If a callback is retried at nfsd4_cb_recall_done() due to
some error, the returned rpc reply crashes here:
@@ -514,6 +514,7 @@ decode_cb_sequence(struct xdr_stream *xdr, struct nfsd4_cb_sequence *res,
u32 dummy;
__be32 *p;
+ BUG_ON(!res);
if (res->cbs_minorversion == 0)
return 0;
[BUG_ON added for demonstration]
This is because the nfsd4_cb_done_sequence() has NULLed out
the task->tk_msg.rpc_resp pointer.
Also eventually the rpc would use the new slot without making
sure it is free by calling nfsd41_cb_setup_sequence().
This problem was introduced by a 4.1 protocol addition patch:
[0421b5c5] nfsd41: Backchannel: Implement cb_recall over NFSv4.1
Which was overlooking the possibility of an RPC callback retries.
For not-4.1 case redoing the _prepare is harmless.
