2019-05-10Add vhost-user-backendMarc-André Lureau
Create a vhost-user-backend object that holds a connection to a vhost-user backend (or "slave" process) and can be referenced from virtio devices that support it. See later patches for input & gpu usage. Note: a previous iteration of this object made it user-creatable, and allowed managed sub-process spawning, but that has been dropped for now.

2019-05-08hw/i2c/smbus_ich9: Fix the confusing contributions-after-2012 statementThomas Huth
The license information in this file is rather confusing. The text declares LGPL first, but then says that contributions after Jan 2012 are licensed under the GPL instead. How should the average user who just downloaded the release tarball know which part is now GPL and which is LGPL? Also, as far as I can see, the file has been added to QEMU *after* January in 2012, so the whole file should be GPL by default instead. Furthermore, looking at the text of the LGPL (see COPYING.LIB in the top directory), the license clearly states in section "3." that one should rather replace the license information in such a case instead. Thus let's clean up the confusing statements and use the proper GPL text only. Message-Id: <1549471435-21887-1-git-send-email-thuth@redhat.com> Signed-off-by: Thomas Huth <thuth@redhat.com>

2019-05-08tests/Makefile: Remove unused test-obj-y variableThomas Huth
I recently noticed that test-obj-y contains a file called tests/check-block-qtest.o which simply does not belong to any .c file and thus wondered why this is not causing any trouble. It is only used to add -Itests to the command line (which refers to the build directory). However, it is not needed because "-iquote $(@D)" already sets this up in rules.mak. Thus we can simply remove this variable. Reviewed-by: Markus Armbruster <armbru@redhat.com> Message-Id: <20190508075527.32164-1-thuth@redhat.com> Signed-off-by: Thomas Huth <thuth@redhat.com>

2019-05-08tests: Force Python I/O encoding for check-qapi-schemaEduardo Habkost
test-qapi.py doesn't force a specific encoding for stderr or stdout, but the reference files used by check-qapi-schema are in UTF-8. This breaks check-qapi-schema under certain circumstances (e.g. if using the C locale and Python < 3.7). We need to make sure test-qapi.py always generate UTF-8 output somehow. On Python 3.7+ we can do it using `sys.stdout.reconfigure(...)`, but we need a solution that works with older Python versions. Instead of trying a hack like reopening sys.stdout and sys.stderr, we can just tell Python to use UTF-8 for I/O encoding when running test-qapi.py. Do it by setting PYTHONIOENCODING.

2019-05-07block/ssh: Implement .bdrv_refresh_filename()Max Reitz
This requires some changes to keep iotests 104 and 207 working. qemu-img info in 104 will now return a filename including the user name and the port, which need to be filtered by adjusting REMOTE_TEST_DIR in common.rc. This additional information has to be marked optional, however (which is simple as REMOTE_TEST_DIR is a regex), because otherwise 197 and 215 would fail: They use it (indirectly) to filter qemu-img create output which contains a backing filename they have passed to it -- which probably does not contain a user name or port number. The problem in 207 is a nice one to have: qemu-img info used to return json:{} filenames, but with this patch it returns nice plain ones. We now need to adjust the filtering to hide the user name (and port number while we are at it). The simplest way to do this is to include both in iotests.remote_filename() so that bdrv_refresh_filename() will not change it, and then iotests.img_info_log() will filter it correctly automatically.

No reasons for not reporting found corruptions as corruptions in case of some internal errors, especially in case of just failed to fix l2 entry (and in this case, missed corruptions may influence comparing logic, when we calculate difference between corruptions fields of two results) Signed-off-by: Vladimir Sementsov-Ogievskiy <vsementsov@virtuozzo.com> Message-id: 20190227131433.197063-6-vsementsov@virtuozzo.com Reviewed-by: Max Reitz <mreitz@redhat.com> Signed-off-by: Max Reitz <mreitz@redhat.com>

2019-05-07qcow2-refcount: avoid eating RAMVladimir Sementsov-Ogievskiy
qcow2_inc_refcounts_imrt() (through realloc_refcount_array()) can eat an unpredictable amount of memory on corrupted table entries, which are referencing regions far beyond the end of file. Prevent this, by skipping such regions from further processing. Interesting that iotest 138 checks exactly the behavior which we fix here. So, change the test appropriately.

2019-05-07iotests: Tweak 221 sizing for different hole granularitiesEric Blake
For some particular configurations of ext4, sizing an image to 84 sectors + 1 byte causes test failures when the size of the hole is rounded to a 4k alignment. Let's instead size things to 128 sectors + 1 byte, as the 64k boundary is more likely to work with various hole granularities.

2019-05-07target/arm: Stop using variable length array in dc_zvaPeter Maydell
Currently the dc_zva helper function uses a variable length array. In fact we know (as the comment above remarks) that the length of this array is bounded because the architecture limits the block size and QEMU limits the target page size. Use a fixed array size and assert that we don't run off it.

2019-05-07target/arm: Implement XPSR GE bitsPeter Maydell
In the M-profile architecture, if the CPU implements the DSP extension then the XPSR has GE bits, in the same way as the A-profile CPSR. When we added DSP extension support we forgot to add support for reading and writing the GE bits, which are stored in env->GE. We did put in the code to add XPSR_GE to the mask of bits to update in the v7m_msr helper, but forgot it in v7m_mrs. We also must not allow the XPSR we pull off the stack on exception return to set the nonexistent GE bits. Correct these errors: * read and write env->GE in xpsr_read() and xpsr_write() * only set GE bits on exception return if DSP present * read GE bits for MRS if DSP present Signed-off-by: Peter Maydell <peter.maydell@linaro.org> Reviewed-by: Richard Henderson <richard.henderson@linaro.org> Message-id: 20190430131439.25251-5-peter.maydell@linaro.org
2019-05-07hw/intc/armv7m_nvic: Don't enable ARMV7M_EXCP_DEBUG from resetPeter Maydell
The M-profile architecture specifies that the DebugMonitor exception should be initially disabled, not enabled. It should be controlled by the DEMCR register's MON_EN bit, but we don't implement that register yet (like most of the debug architecture for M-profile). Note that BKPT instructions will still work, because they will be escalated to HardFault.

2019-05-07hw/arm/armv7m_nvic: Check subpriority in nvic_recompute_state_secure()Peter Maydell
Rule R_CQRV says that if two pending interrupts have the same group priority then ties are broken by looking at the subpriority. We had a comment describing this but had forgotten to actually implement the subpriority comparison. Correct the omission. (The further tie break rules of "lowest exception number" and "secure before non-secure" are handled implicitly by the order in which we iterate through the exceptions in the loops.)
