From 9e51ca3dc11b4abe2e5145837ae80863fc300646 Mon Sep 17 00:00:00 2001

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.
Fixes: bbf1c51392 (api: Give aio_opt_go a completion callback)

From 22572f8ac13e2e8daf91d227eac2f384303fb5b4 Mon Sep 17 00:00:00 2001

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.

Note that while the use of NBD_CMD_TRIM can create data corruption, it is

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
(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)

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.

%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.
