Subject: [PATCH] copy/copy-nbd-to-sparse-file.sh: Skip test unless nbdkit
available.
This test used nbdkit without checking it is available, which broke
the test on RHEL 8 i686.
Fixes: commit 28fe8d9d8d1ecb491070d20f22e2f34bb147f19f
(cherry picked from commit 781cb44b63a87f2d5f40590ab8c446ad2e7b6702)

Subject: [PATCH] generator: Fix assertion in ext-mode BLOCK_STATUS,
CVE-2023-5871
Another round of fuzz testing revealed that when a server negotiates
extended headers and replies with a 64-bit flag value where the client
used the 32-bit API command, we were correctly flagging the server's
response as being an EOVERFLOW condition, but then immediately failing
in an assertion failure instead of reporting it to the application.
The following one-byte change to qemu.git at commit fd9a38fd43 allows
the creation of an intentionally malicious server:

and can then be detected with the following command line:
$ nbdsh -c - <<\EOF

> pass
>
> h.connect_systemd_socket_activation(["/path/to/bad/qemu-nbd",

nbdsh: generator/states-reply-chunk.c:626: enter_STATE_REPLY_CHUNK_REPLY_RECV_BS_ENTRIES: Assertion `(len | flags) <= UINT32_MAX' failed.
Aborted (core dumped)
whereas a fixed libnbd will give:
nbdsh: command line script failed: nbd_block_status: block-status: command failed: Value too large for defined data type
We can either relax the assertion (by changing to 'assert ((len |
flags) <= UINT32_MAX || cmd->error)'), or intentionally truncate flags
to make the existing assertion reliable. This patch goes with the
latter approach.
Sadly, this crash is possible in all existing 1.18.x stable releases,
if they were built with assertions enabled (most distros do this by
default), meaning a malicious server has an easy way to cause a Denial
of Service attack by triggering the assertion failure in vulnerable
clients, so we have assigned this CVE-2023-5871. Mitigating factors:
the crash only happens for a server that sends a 64-bit status block
reply (no known production servers do so; qemu 8.2 will be the first
known server to support extended headers, but it is not yet released);
and as usual, a client can use TLS to guarantee it is connecting only
to a known-safe server. If libnbd is compiled without assertions,
there is no crash or other mistaken behavior; and when assertions are
enabled, the attacker cannot accomplish anything more than a denial of
service.

Subject: [PATCH] tests: Check behavior of
nbd_set_strict_mode(STRICT_AUTO_FLAG)
While developing extended header support for qemu 8.2, I needed a way
to make libnbd quickly behave as a non-compliant client to test corner
cases in qemu's server code; so I wrote commit 5c1dae9236 ("api: Add
LIBNBD_STRICT_AUTO_FLAG to nbd_set_strict", v1.18.0) to meet my needs.
However, I failed to codify my manual tests of that bit into a unit
test for libnbd, until now. Most sane clients will never call
nbd_set_strict_mode() in the first place (after all, it is explicitly
documented as an integration tool, which is how I used it with my qemu
code development), but it never hurts to make sure we don't break it
even for the relatively small set of users that would ever use it.
The test added here runs in two parts; if you get a SKIP despite
having qemu-nbd, then the first part ran successfully before the
second half gave up due to lack of extended headers in qemu
(presumably qemu 8.1 or older); if you get a PASS, then both parts
were run. However, both parts are inherently fragile, depending on
behavior known to be in qemu 8.2 - while it is unlikely to change in
future qemu releases (at least as long as I continue to maintain NBD
code there), the fact that we are intentionally violating the NBD
protocol means a different server is within its rights to behave
differently than qemu 8.2 did. Hence this test lives in interop/
rather than tests/ because of its strong ties to a particular qemu.

Subject: [PATCH] opt_go: Tolerate unplanned server death
While debugging some experimental nbdkit code that was triggering an
assertion failure in nbdkit, I noticed a secondary failure of nbdsh
also dying from an assertion:
libnbd: debug: nbdsh: nbd_opt_go: transition: NEWSTYLE.OPT_GO.SEND -> DEAD
libnbd: debug: nbdsh: nbd_opt_go: option queued, ignoring state machine failure
nbdsh: opt.c:86: nbd_unlocked_opt_go: Assertion `nbd_internal_is_state_negotiating (get_next_state (h))' failed.
Although my trigger was from non-production nbdkit code, libnbd should
never die from an assertion failure merely because a server
disappeared at the wrong moment during an incomplete reply to
NBD_OPT_GO or NBD_OPT_INFO. If this is assigned a CVE, a followup
patch will add mention of it in docs/libnbd-security.pod.
Fixes: bbf1c51392 (api: Give aio_opt_go a completion callback)

Subject: [PATCH] copy: Pass in dummy variable rather than &errno to callback
In several places where asynch handlers manually call the provided
nbd_completion_callback, the value of errno is indeterminate (for
example, in file-ops.c:file_asynch_read(), the previous call to
file_synch_read() already triggered exit() on error, but does not
guarantee what is left in errno on success). As the callback should
be paying attention to the value of *error (to be fixed in the next
patch), we are better off ensuring that we pass in a pointer to a
known-zero value. Besides, passing in &errno carries a risk that if
the callback uses any other library function that alters errno prior
to dereferncing *error, it will no longer see the value we passed in.
Thus, it is easier to use a dummy variable on the stack than to mess
around with errno and it's magic macro expansion into a thread-local
storage location.
Note that several callsites then check if the callback returned -1,
and if so assume that the callback has caused errno to now have a sane
value to pass on to perror. In theory, the fact that we are no longer
passing in &errno means that if the callback assigns into *error but
did not otherwise affect errno (a tenuous assumption, given our
argument above that we could not even guarantee that the callback does
not accidentally alter errno prior to reading *error), our perror call
would no longer reflect the intended error value from the callback.
But in practice, since the callback never actually returned -1, nor
even assigned into *error, the call to perror is dead code; although I
have chosen to defer that additional cleanup to the next patch.

Subject: [PATCH] copy: CVE-2022-0485: Fail nbdcopy if NBD read or write fails
nbdcopy has a nasty bug when performing multi-threaded copies using
asynchronous nbd calls - it was blindly treating the completion of an
asynchronous command as successful, rather than checking the *error
parameter. This can result in the silent creation of a corrupted
image in two different ways: when a read fails, we blindly wrote
garbage to the destination; when a write fails, we did not flag that
the destination was not written.
Since nbdcopy already calls exit() on a synchronous read or write
failure to a file, doing the same for an asynchronous op to an NBD
server is the simplest solution. A nicer solution, but more invasive
to code and thus not done here, might be to allow up to N retries of
the transaction (in case the read or write failure was transient), or
even having a mode where as much data is copied as possible (portions
of the copy that failed would be logged on stderr, and nbdcopy would
still fail with a non-zero exit status, but this would copy more than
just stopping at the first error, as can be done with rsync or
ddrescue).
Note that since we rely on auto-retiring and do NOT call
nbd_aio_command_completed, our completion callbacks must always return
1 (if they do not exit() first), even when acting on *error, so as not
leave the command allocated until nbd_close. As such, there is no
sane way to return an error to a manual caller of the callback, and
therefore we can drop dead code that calls perror() and exit() if the
callback "failed". It is also worth documenting the contract on when
we must manually call the callback during the asynch_zero callback, so
that we do not leak or double-free the command; thankfully, all the
existing code paths were correct.
The added testsuite script demonstrates several scenarios, some of
which fail without the rest of this patch in place, and others which
showcase ways in which sparse images can bypass errors.
Once backports are complete, a followup patch on the main branch will
edit docs/libnbd-security.pod with the mailing list announcement of
the stable branch commit ids and release versions that incorporate
this fix.

a potential leak of nbdcopy heap contents into the destination.

From 764fc45a258c08177d01b6b6b6a0e431ee29089a Mon Sep 17 00:00:00 2001

Subject: [PATCH] interop: Pass -DCERTS and -DPSK as strings
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit
Rather than implicitly defining the certificates dir or PSK file in
interop.c, pass the actual paths from the Makefile.
This also allows -DCERTS=NULL which is interpreted as not calling
nbd_set_tls_certificates at all. This makes the test added in a
subsequent commit possible.
No real change here, just refactoring the tests.

Subject: [PATCH] tests: Factor out some common Makefile flags
We can use AM_CPPFLAGS, AM_CFLAGS etc to factor out some common flags
in the tests. Note the rules here are complicated, see:
https://www.gnu.org/software/automake/manual/html_node/Flag-Variables-Ordering.html
and for unclear reasons there is no AM_LDADD nor any workaround:
https://stackoverflow.com/questions/29252969/automake-am-ldadd-workaround
This commit is mostly pure refactoring but it also tries to make the
flags usage more consistent across tests so it may have side-effects
like enabling more warnings.

Subject: [PATCH] tests/connect-uri.c: Ensure Unix domain socket is cleaned up
on exit
Commit 70f83fed13 ("tests: Create test sockets in /tmp instead of
local directory.") aimed to create sockets with short path names in
/tmp. However it never cleaned them up. Worse still, every time the
Makefile was evaluated at all a temporary file was created.
Fix this properly in the C file.
Fixes: commit 70f83fed131c7e52b1a31a28d9acaf19f6c11d57

Subject: [PATCH] lib: Allow tls-certificates=<DIR> query parameter in URIs
For nbd_connect_uri, this allows a non-default path to a certificates
directory to be specified. For example:
nbds+unix://user@/?socket=/tmp/sock&tls-certificates=tests/pki
nbd_get_uri is also extended to produce the tls-certificates query
field if nbd_set_tls_certificates was called.
The main work here is extending the test suite so it actually tests
TLS URIs properly. Firstly we need to add --tls-verify-peer to the
nbdkit command line so it checks TLS client credentials at all
(previously it enabled TLS but didn't verify the client). Then we
need to add tests which use TLS certificates (previously only PSK was
being tested). And finally I loosened the rules for comparing URIs
since the order that query strings are returned by nbd_get_uri is not
necessarily the same as the query strings in nbd_connect_uri.
