[nbdkit PATCH] rust: prevent dead_code warning
by Thomas Weißschuh
rustc 1.64.0 generates warnings for the mocked Server.
This leads to a failure of test.sh.
```
warning: associated function `expect` is never used
--> tests/common/mod.rs:49:1
|
49 | / mock!{
50 | | pub Server {}
51 | | impl Server for Server {
52 | | fn cache(&self, count: u32, offset: u64) -> Result<()>;
... |
86 | | }
87 | | }
| |_^
|
= note: `#[warn(dead_code)]` on by default
```

bug in gnutls_init()
by Eric Blake
I just fixed a bug in nbdkit for incorrectly calling
free(gnutls_session_t) after gnutls_init(&session, ...) fails:
https://gitlab.com/nbdkit/nbdkit/-/commit/40faf3dfb20c06b9c5faa0a122607e3...
But in the process, I was browsing the source code to gnutls_init() to
see why Coverity wasn't flagging free(opaque_type) as fishy, and found
that there is a nasty lurking bug:
int gnutls_init(gnutls_session_t * session, unsigned int flags)
{
int ret;
FAIL_IF_LIB_ERROR;
*session = gnutls_calloc(1, sizeof(struct gnutls_session_int));
Note that *session is left uninitialized if FAIL_IF_LIB_ERROR; causes
an early return GNUTLS_E_LIB_IN_ERROR_STATE. If a caller (properly)
treats gnutls_session_t as an opaque type, and does not try to
zero-initialize it (as there is no way to know that 0 is a safe value
for an opaque type), then writing:
gnutls_session_t session;
int err = gnutls_init (&session, GNUTLS_SERVER);
if (err < 0)
gnutls_deinit (session);
is a bug waiting to happen, because it WILL cause gnutls_deinit() to
attempt to dereference an uninitialized pointer if session remains
uninitialized because of an earlier library error.

[libnbd PATCH 0/2] Expose tls and structured_reply in nbdinfo
by Eric Blake
Indirectly related to my recent additions of nbd_opt_starttls() and
nbd_opt_structured_reply(); also a precursor to further extending this
part of nbdinfo to expose when 64-bit extensions are negotiated.
Eric Blake (2):
info: Expose whether structured replies were negotiated
info: Add --is tls, --can structured-reply
