+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
+(cherry picked from commit f5955c4c5bb0269e192b906a3ef98601aa63ad59)
+(cherry picked from commit 502f0b59ec1dbd64c6c64279316e03540258a54c)

+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)

+MIME-Version: 1.0
+Content-Type: text/plain; charset=UTF-8
+Content-Transfer-Encoding: 8bit
+
+Older versions of libnbd didn't always check the server certificate.
+Since some clients might be depending on this, allow
+?tls-verify-peer=false in URIs to skip this check.
