Subject: [PATCH 2/2] nbd/server: Mark negotiation functions as coroutine_fn
RH-Author: Eric Blake <eblake@redhat.com>
RH-MergeRequest: 239: avoid destination hang on NBD+TLS storage migration
RH-Jira: RHEL-33440

RH-Commit: [2/2] acf61b854f80365993d24bcd1d110ed3518b22fa (ebblake/centos-qemu-kvm)
nbd_negotiate() is already marked coroutine_fn. And given the fix in
the previous patch to have nbd_negotiate_handle_starttls not create
and wait on a g_main_loop (as that would violate coroutine
constraints), it is worth marking the rest of the related static
functions reachable only during option negotiation as also being
coroutine_fn.

Subject: [PATCH 1/2] nbd/server: do not poll within a coroutine context
RH-Author: Eric Blake <eblake@redhat.com>
RH-MergeRequest: 239: avoid destination hang on NBD+TLS storage migration
RH-Jira: RHEL-33440
RH-Acked-by: Stefan Hajnoczi <stefanha@redhat.com>

RH-Commit: [1/2] 27963e92aacca8ed43994113b645f472fba8f8bc (ebblake/centos-qemu-kvm)
Coroutines are not supposed to block. Instead, they should yield.
The client performs TLS upgrade outside of an AIOContext, during
synchronous handshake; this still requires g_main_loop. But the
server responds to TLS upgrade inside a coroutine, so a nested
g_main_loop is wrong. Since the two callbacks no longer share more
than the setting of data.complete and data.error, it's just as easy to
use static helpers instead of trying to share a common code path. It
is also possible to add assertions that no other code is interfering
with the eventual path to qio reaching the callback, whether or not it
required a yield or main loop.
Fixes: f95910f ("nbd: implement TLS support in the protocol negotiation")
