-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:

-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.

-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
+(cherry picked from commit f5955c4c5bb0269e192b906a3ef98601aa63ad59)

+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.
+
