-Subject: [PATCH] generator: Print full error in handle_reply_error
-
-Print the full error from the server during handshaking.  This
-modifies the contract of handle_reply_error so it calls set_error,
-which can be overridden by callers or ignored completely.
-
-(cherry picked from commit cf49a49adc8abc8c917437db7461ed9956583877)

+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.

+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.

+(cherry picked from commit 8d444b41d09a700c7ee6f9182a649f3f2d325abb)
+Conflicts:
+	copy/nbdcopy.h - copyright context
+	copy/null-ops.c - no backport of 0b16205e "copy: Implement "null:"
+ destination."
+        copy/copy-nbd-error.sh - no backport of d5f65e56 ("copy: Do not use
+ trim for zeroing"), so one test needed an additional error-trim-rate;
+ no backport of 4ff9e62d (copy: Add --request-size option") and friends, so
+ this version uses larger transactions, so change error rate of 0.5 to 1;
+ no backport of 0b16205e "copy: Implement "null:" destination.", so use
+ nbdkit null instead
+Note that while the use of NBD_CMD_TRIM can create data corruption, it is
+not as severe as what this patch fixes, since trim corruption will only
+expose what had previously been on the disk, compared to this patch fixing
+a potential leak of nbdcopy heap contents into the destination.

+Subject: [PATCH] build: Move to minimum gnutls >= 3.5.18
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+This version matches current qemu.
+
+RHEL 7 gnutls is too old (lacks gnutls_session_set_verify_cert), which
+means TLS will be disabled on this platform.  RHEL 8 has gnutls 3.6.14.
+
+I also unconditionally enabled the gnutls/socket.h header.  This
+header was added in 2016 (gnutls 3.5.3), so it's not present in RHEL 7.
+
+On RHEL 7 the configure-time test now prints:
+
+  checking for GNUTLS... no
+  configure: WARNING: gnutls not found or < 3.5.18, TLS support will be disabled.
+  ...
+  Optional library features:
+      TLS support ............................ no

+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.

+Subject: [PATCH] lib/crypto.c: Check server certificate even when using system
+ CA
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+The previous code checked the server certificate only when a custom
+certificate directory was set (ie.  nbd_set_tls_certificates /
+?tls-certificates=DIR).  In the fallback case where we use the system
+CA, we never called gnutls_session_set_verify_cert and so the server
+certificate was never checked.
+
+Move the call to gnutls_session_set_verify_cert later so it is called
+on both paths.
+
+If the server certificate does not match the hostname you will see:
+
+nbdinfo: nbd_connect_uri: gnutls_handshake: Error in the certificate verification. (15/1)

+Subject: [PATCH] lib/crypto.c: Allow CA verification even if h->hostname is
+ not set
+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Calling gnutls_session_set_verify_cert with the hostname parameter set
+to NULL is permitted:
+https://www.gnutls.org/manual/html_node/Core-TLS-API.html#gnutls_005fsession_005fset_005fverify_005fcert
+
+It means that the server's hostname in the certificate will not be
+verified but we can at least check that the certificate was signed by
+the CA.  This allows the CA to be checked even for connections over
+Unix domain sockets.
+
+Example:
+
+  $ rm -f /tmp/sock
+  $ nbdkit -U /tmp/sock -f --tls=require --tls-certificates=$HOME/d/nbdkit/tests/pki memory 1G &
+
+Before this change:
+
+  $ nbdinfo 'nbds+unix://?socket=/tmp/sock'
+  protocol: newstyle-fixed with TLS, using structured packets
+  export="":
+	export-size: 1073741824 (1G)
+	content: data
+	uri: nbds+unix:///?socket=/tmp/sock
+  [etc]
+
+(works because it never called gnutls_session_set_verify_cert).
+
+After this change:
+
+  $ nbdinfo 'nbds+unix://?socket=/tmp/sock'
+  nbdinfo: nbd_connect_uri: gnutls_handshake: Error in the certificate verification. (15/1)
+
+(fails because system CA does not know about nbdkit's certificate
+which is signed by the CA from the nbdkit/tests/pki directory)
+
+  $ nbdinfo 'nbds+unix://?socket=/tmp/sock&tls-certificates=/home/rjones/d/nbdkit/tests/pki'
+  protocol: newstyle-fixed with TLS, using structured packets
+  export="":
+	export-size: 1073741824 (1G)
+	content: data
+	uri: nbds+unix:///?socket=/tmp/sock&tls-certificates=/home/rjones/d/nbdkit/tests/pki
+  [etc]
+
+(works because we supplied the correct CA)

+Older versions of libnbd didn't always check the server certificate.

+%description
+NBD — Network Block Device — is a protocol for accessing Block Devices
+(hard disks and disk-like things) over a Network.
+
+This is the NBD client library in userspace, a simple library for
+writing NBD clients.
+
+The key features are:
+
+ * Synchronous and asynchronous APIs, both for ease of use and for
+   writing non-blocking, multithreaded clients.
+
+ * High performance.
+
+ * Minimal dependencies for the basic library.
+
+ * Well-documented, stable API.
+
+ * Bindings in several programming languages.
