 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.

 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.

 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.

 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] 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] 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] 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)

 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

 (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] 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] lib/uri.c: Allow tls-verify-peer to be overridden in URIs
 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.
