2018-07-30block/qapi: Include anonymous BBs in query-blockstatsKevin Wolf
Consistent with query-block, query-blockstats should not only include named BlockBackends, but also those that are anonymous, but belong to a device model. Signed-off-by: Kevin Wolf <kwolf@redhat.com> Reviewed-by: Eric Blake <eblake@redhat.com>
2018-07-30block/qapi: Add 'qdev' field to query-blockstats resultKevin Wolf
Like for query-block, the client needs to identify which BlockBackend the returned data is for. Anonymous BlockBackends are identified by the device model they are attached to. Add a 'qdev' field that contains the qdev ID or QOM path of the attached device model. Signed-off-by: Kevin Wolf <kwolf@redhat.com> Reviewed-by: Eric Blake <eblake@redhat.com>
2018-07-30file-posix: Fix write_zeroes with unmap on block devicesKevin Wolf
The BLKDISCARD ioctl doesn't guarantee that the discarded blocks read as all-zero afterwards, so don't try to abuse it for zero writing. We try to only use this if BLKDISCARDZEROES tells us that it is safe, but this is unreliable on older kernels and a constant 0 in newer kernels. In other words, this code path is never actually used with newer kernels, so we don't even try to unmap while writing zeros. This patch removes the abuse of discard for writing zeroes from file-posix and instead adds a new function that uses interfaces that are actually meant to deallocate and zero out at the same time. Only if those fail, it falls back to zeroing out without unmap. We never fall back to a discard operation any more that may or may not result in zeros. Signed-off-by: Kevin Wolf <kwolf@redhat.com>
2018-07-30block: Fix documentation for BDRV_REQ_MAY_UNMAPKevin Wolf

2018-07-28qstring: Fix qstring_from_substr() not to provoke int overflowliujunjie
qstring_from_substr() parameters @start and @end are of type int. blkdebug_parse_filename(), blkverify_parse_filename(), nbd_parse_uri(), and qstring_from_str() pass @end values of type size_t or ptrdiff_t. Values exceeding INT_MAX get truncated, with possibly disastrous results. Such huge substrings seem unlikely, but we found one in a core dump, where "info tlb" executed via QMP's human-monitor-command apparently produced 35 GiB of output. Fix by changing the parameters size_t.

2018-07-24tests: fix TLS handshake failure with TLS 1.3Daniel P. Berrangé
When gnutls negotiates TLS 1.3 instead of 1.2, the order of messages sent by the handshake changes. This exposed a logic bug in the test suite which caused us to wait for the server to see handshake completion, but not wait for the client to see completion. The result was the client didn't receive the certificate for verification and the test failed. This is exposed in Fedora 29 rawhide which has just enabled TLS 1.3 in its GNUTLS builds.

2018-07-24tests: use error_abort in places expecting errorsDaniel P. Berrangé
Most of the TLS related tests are passing an in a "Error" object to methods that are expected to fail, but then ignoring any error that is set and instead asserting on a return value. This means that when an error is unexpectedly raised, no information about it is printed out, making failures hard to diagnose. Changing these tests to pass in &error_abort will make unexpected failures print messages to stderr.

2018-07-24tests: don't silence error reporting for all testsDaniel P. Berrangé
The test-vmstate test is a bit chatty because it triggers various expected failure scenarios and the code in question uses error_report instead of accepting 'Error **errp' parameters. To silence this test the stubs for error_vprintf() were changed to send errors via g_test_message() instead of stderr: commit 28017e010ddf6849cfa830e898da3e44e6610952 Author: Paolo Bonzini <pbonzini@redhat.com> Date: Mon Oct 24 18:31:03 2016 +0200 tests: send error_report to test log Implement error_vprintf to send the output of error_report to the test log. This silences test-vmstate. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com> Message-Id: <1477326663-67817-3-git-send-email-pbonzini@redhat.com> Unfortunately this change has global impact across the entire test suite and means that when tests fail for unexpected reasons, the message is not displayed on stderr. eg when using &error_abort in a call the test merely prints Unexpected error in qcrypto_tls_session_check_certificate() at crypto/tlssession.c:280: and the actual error message is hidden, making it impossible to diagnose the failure. This is especially problematic in CI or build systems where it isn't possible to easily pass the --debug-log flag to tests and re-run with the test log visible. This change makes the previous big hammer much more nuanced, providing a flag in the stub error_vprintf() that can used on a per-test basis to silence the errors. Only the test-vmstate silences errors initially. Reviewed-by: Philippe Mathieu-Daudé <f4bug@amsat.org> Tested-by: Philippe Mathieu-Daudé <f4bug@amsat.org> Signed-off-by: Daniel P.

2018-07-24migration: disallow recovery for release-ramPeter Xu
Postcopy recovery won't work well with release-ram capability since release-ram will drop the page buffer as long as the page is put into the send buffer. So if there is a network failure happened, any page buffers that have not yet reached the destination VM but have already been sent from the source VM will be lost forever. Let's refuse the client from resuming such a postcopy migration. Luckily release-ram was designed to only be used when src and destination VMs are on the same host, so it should be fine.

When a check fails we currently just report why we failed. This is not totally helpful to people who want to boot-strap a new image. Report a hint as to why it failed. Signed-off-by: Alex Bennée <alex.bennee@linaro.org> Suggested-by: Fam Zheng <famz@redhat.com>
2018-07-24docker: drop QEMU_TARGET check, fallback in EXECUTABLE not setAlex Bennée
The addition of QEMU_TARGET was intended to ensure we fall back to checking for the existence of an image if the build system was not currently configured to build it. However this breaks the direct use of the rule for building custom binfmt_misc images. We already check for EXECUTABLE so let us just use that as a proxy for deciding if we are just going to check the image exits.

2018-07-24docker: add expansion for docker-test-FOO to Makefile.includeAlex Bennée
This allows us to run a particular test on all docker images. For example: make docker-test-unit Will run the unit tests on every supported image. At the same time rename docker-test to docker-all-tests to be clearer.

2018-07-24docker: add test-unit runnerAlex Bennée
This test doesn't even build QEMU, it just builds and runs all the unit tests. Intended to make checking unit tests on all docker images easier.

2018-07-24docker: Makefile.include don't include partial imagesAlex Bennée
Rename DOCKER_INTERMEDIATE_IMAGES to DOCKER_PARTIAL_IMAGES and add the incomplete cross compiler images that can build tests but can't build QEMU itself. We also add debian, debian-bootstrap and the tricode images to the list.

2018-07-24docker: gracefully skip check_qemuAlex Bennée
Not all our images are able to run the tests. Rather than use features we can just check for the existence and run-ability of gtester. If the image has been setup for binfmt_misc it will be able to run anyway.

2018-07-24docker: move make check into check_qemu helperAlex Bennée
Not all docker images can run the check step. Let's move everything into a common helper so we don't need to replicate checks in the future. Signed-off-by: Alex Bennée <alex.bennee@linaro.org> Reviewed-by: Philippe Mathieu-Daudé <f4bug@amsat.org> Tested-by: Philippe Mathieu-Daudé <f4bug@amsat.org>
