2017-05-05MAINTAINERS: Add "R:" tag for self-appointed reviewersPaul E. McKenney
Some people are not content with the amount of mail they get, and would like to be CCed on patches for areas they do not maintain. Let them satisfy their own appetite for qemu-devel messages. Seriously: the purpose here is a bit different from the Linux kernel. While Linux uses "R" to designate non-maintainers for reviewing patches in a given area, in QEMU I would also like to use "R" so that people can delegate sending pull requests while keeping some degree of oversight.

2017-05-05hax: Fix memory mapping de-duplication logicYu Ning
hax_update_mapping() avoids unnecessary and potentially expensive calls to HAX_VM_IOCTL_SET_RAM by computing the net result (i.e. effective mapping changes) of each MemoryRegion transaction, with the help of a linked list of HAXMapping objects. However, when processing a new mapping that overlaps with an existing mapping in the list, it fails to handle the case where the start address of the new mapping is above that of the existing mapping in the guest physical address space. This happens when QEMU is launched with "-machine q35 -enable-hax", which involves the following MemoryRegion transaction for digging the VGA hole: region_del: 0x00000000->0x08000000 VA 05fa0000 ('pc.ram') region_add: 0x00000000->0x000a0000 VA 05fa0000 ('pc.ram') region_add: 0x000a0000->0x000c0000 VA 00000000 ('vga-lowmem') region_add: 0x000c0000->0x08000000 VA 06060000 ('pc.ram') where the third MemoryRegion is MMIO and is ignored. The current de-duplication logic handles the last MemoryRegion incorrectly and produces the following result: hax_mapping_dump_list updates: + 0x000c0000->0x08000000 VA 0x06060000 - 0x07fe0000->0x08000000 VA 0x0df80000 which is why VGA emulation does not work for Q35. With this patch, one can see VGA output as Q35 boots up. Note that Q35 support also requires a change to HAXM kernel module, which is not available in the current HAXM release (6.1.2). + Add a warning if the input MemoryRegion is a ROM device, which is not supported by HAXM kernel module at this time.

2017-05-05checkpatch: Disallow glib asserts in main codeDr. David Alan Gilbert
Glib commit a6a875068779 (from 2013) made many of the glib assert macros non-fatal if a flag is set. This causes two problems: a) Compilers moan that your code is unsafe even though you've put an assert in before the point of use. b) Someone evil could, in a library, call g_test_set_nonfatal_assertions() and cause our assertions in important places not to fail and potentially allow memory overruns. Ban most of the glib assertion functions (basically everything except g_assert and g_assert_not_reached) except in tests/ This makes checkpatch gives an error such as: ERROR: Use g_assert or g_assert_not_reached #77: FILE: vl.c:4725: + g_assert_cmpstr("Chocolate", >, "Cheese"); Signed-off-by: Dr. David Alan Gilbert <dgilbert@redhat.com> Message-Id: <20170427165526.19836-1-dgilbert@redhat.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2017-05-05trace: add qemu mutex lock and unlock trace eventsJose Ricardo Ziviani
These trace events were very useful to help me to understand and find a reordering issue in vfio, for example: qemu_mutex_lock locked mutex 0x10905ad8 vfio_region_write (0001:03:00.0:region1+0xc0, 0x2020c, 4) qemu_mutex_unlock unlocked mutex 0x10905ad8 qemu_mutex_lock locked mutex 0x10905ad8 vfio_region_write (0001:03:00.0:region1+0xc4, 0xa0000, 4) qemu_mutex_unlock unlocked mutex 0x10905ad8 that also helped me to see the desired result after the fix: qemu_mutex_lock locked mutex 0x10905ad8 vfio_region_write (0001:03:00.0:region1+0xc0, 0x2000c, 4) vfio_region_write (0001:03:00.0:region1+0xc4, 0xb0000, 4) qemu_mutex_unlock unlocked mutex 0x10905ad8 So it could be a good idea to have these traces implemented. It's worth mentioning that they should be surgically enabled during the debugging, otherwise it can flood the trace logs with lock/unlock messages.

2017-05-05use _Static_assert in QEMU_BUILD_BUG_ONAndreas Grapentin
QEMU_BUILD_BUG_ON should use C11's _Static_assert, if the compiler supports it, to provide more readable messages on failure. We check for _Static_assert in configure, and set CONFIG_STATIC_ASSERT accordingly. QEMU_BUILD_BUG_ON invokes _Static_assert if CONFIG_STATIC_ASSERT is defined, and reverts to the old way otherwise. That way, systems without C11 conforming compiler will still have the old messages, as verified by intentionally breaking the configure check. the following example output was generated by inverting the condition in QEMU_BUILD_BUG_ON: without _Static_assert: > In file included from /qemu/include/qemu/osdep.h:36:0, > from /qemu/qga/commands.c:13: > /qemu/qga/commands.c: In function ‘qmp_guest_exec_status’: > /qemu/include/qemu/compiler.h:89:12: error: negative width in bit-field ‘<anonymous>’ > struct { \ > ^ > /qemu/include/qemu/compiler.h:96:38: note: in expansion of macro QEMU_BUILD_BUG_ON_STRUCT’ > #define QEMU_BUILD_BUG_ON(x) typedef QEMU_BUILD_BUG_ON_STRUCT(x) \ > ^~~~~~~~~~~~~~~~~~~~~~~~ > /qemu/include/qemu/atomic.h:146:5: note: in expansion of macro ‘QEMU_BUILD_BUG_ON’ > QEMU_BUILD_BUG_ON(sizeof(*ptr) > sizeof(void *)); \ > ^~~~~~~~~~~~~~~~~ > /qemu/include/qemu/atomic.h:417:5: note: in expansion of macro ‘atomic_load_acquire’ > atomic_load_acquire(ptr) > ^~~~~~~~~~~~~~~~~~~ > /qemu/qga/commands.c:160:21: note: in expansion of macro ‘atomic_mb_read’ > bool finished = atomic_mb_read(&gei->finished); > ^~~~~~~~~~~~~~ with _Static_assert: > In file included from /qemu/include/qemu/osdep.h:36:0, > from /qemu/qga/commands.c:13: > /qemu/qga/commands.c: In function ‘qmp_guest_exec_status’: > /qemu/include/qemu/compiler.h:94:30: error: static assertion failed: "not expecting: sizeof(*&gei->finished) > sizeof(void *)" > #define QEMU_BUILD_BUG_ON(x) _Static_assert((x), #x) > ^ > /qemu/include/qemu/atomic.h:146:5: note: in expansion of macro ‘QEMU_BUILD_BUG_ON’ > QEMU_BUILD_BUG_ON(sizeof(*ptr) > sizeof(void *)); \ > ^~~~~~~~~~~~~~~~~ > /qemu/include/qemu/atomic.h:417:5: note: in expansion of macro ‘atomic_load_acquire’ > atomic_load_acquire(ptr) > ^~~~~~~~~~~~~~~~~~~ > /qemu/qga/commands.c:160:21: note: in expansion of macro ‘atomic_mb_read’ > bool finished = atomic_mb_read(&gei->finished); > ^~~~~~~~~~~~~~ Signed-off-by: Andreas Grapentin <andreas@grapentin.org> Message-Id: <20170314165953.18506-1-andreas@grapentin.org> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>

2017-05-03char: Fix removing wrong GSource that be found by fd_in_tagzhanghailiang
We use fd_in_tag to find a GSource, fd_in_tag is return value of g_source_attach(GSource *source, GMainContext *context), the return value is unique only in the same context, so we may get the same values with different 'context' parameters. It is no problem to find the right fd_in_tag by using g_main_context_find_source_by_id(GMainContext *context, guint source_id) while there is only one default main context. But colo-compare tries to create/use its own context, and if we pass wrong 'context' parameter with right fd_in_tag, we will find a wrong GSource to handle. We tried to fix the related codes in commit b43decb015a6efeb9e3cdbdb80f6547ad7248a4c, but it didn't fix the bug completely, because we still have some codes didn't pass *right* context parameter for remove_fd_in_watch(). Let's fix it by record the GSource directly instead of fd_in_tag.

2017-05-03hw/i386: Use Rev3 FADT (ACPI 2.0) instead of Rev1 to improve guest OS support.Phil Dennis-Jordan
This updates the FADT generated for x86/64 machine types from Revision 1 to 3. (Based on ACPI standard 2.0 instead of 1.0) The intention is to expose the reset register information to guest operating systems which require it, specifically OS X/macOS. Revision 1 FADTs do not contain the fields relating to the reset register. The new layout and contents remains backwards-compatible with operating systems which only support ACPI 1.0, as the existing fields are not modified by this change, as the 64-bit and 32-bit variants are allowed to co-exist according to the ACPI 2.0 standard. No regressions became apparent in tests with a range of Windows (XP-10) and Linux versions. The BIOS tables test suite's FADT checksum test has also been updated to reflect the new FADT layout and content.

2017-04-27qga: Add `guest-get-timezone` commandVinzenz Feenstra
Adds a new command `guest-get-timezone` reporting the currently configured timezone on the system. The information on what timezone is currently is configured is useful in case of Windows VMs where the offset of the hardware clock is required to have the same offset. This can be used for management systems like `oVirt` to detect the timezone difference and warn administrators of the misconfiguration.

When the command "guest-fsfreeze-freeze" is executed it causes the VSS service to log the error below in the Event Viewer.

2017-04-26qga-win: Fix a bug where qemu-ga service is stuck during stop operationSameeh Jubran
After triggering a freeze command without any following thaw command, qemu-ga will not respond to stop operation. This behaviour is wanted on Linux as there is no time limit for a freeze command and we want to prevent quitting in the middle of freeze, on the other hand on Windows the time limit for freeze is 10 seconds, so we should wait for the timeout, thaw the file system and quit.

2017-04-26qga-win: Enable 'can-offline' field in 'guest-get-vcpus' replySameeh Jubran
The QGA schema states: @can-offline: Whether offlining the VCPU is possible. This member is always filled in by the guest agent when the structure is returned, and always ignored on input (hence it can be omitted then). Currently 'can-offline' is missing entirely from the reply. This causes errors in libvirt which is expecting the reply to be compliant with the schema docs.

This reverts commit 0fc8aec7de64f2bf83a274a2a38b938ce03425d2. In commit 2dfe5113b11 we split a trace event with a lot of arguments in two, because the UST trace backend has a limit on the number of arguments you can have in a single trace event. Unfortunately we subsequently forgot about this, and in commit 0fc8aec7de64f2 we merged the two trace events again, recreating the "UST backend doesn't build" bug.

2017-04-26tests: Add a tester for HMP commandsThomas Huth

2017-04-26libqtest: Ignore QMP events when parsing the response for HMP commandsThomas Huth
When running certain HMP commands (like "device_del") via QMP, we can sometimes get a QMP event in the response first, so that the "g_assert(ret)" statement in qtest_hmp() triggers and the test fails.

into staging ppc patch queue 2017-04-26 Here's a respind of my first pull request for qemu-2.10, consisting of assorted patches which have accumulated while qemu-2.9 stabilized. Highlights are: * Rework / cleanup of the XICS interrupt controller * Substantial improvement to the 'powernv' machine type - Includes an MMIO XICS version * POWER9 support improvements - POWER9 guests with KVM - Partial support for POWER9 guests with TCG * IOMMU and VFIO improvements * Assorted minor changes There are several IPMI patches here that aren't usually in my area of maintenance, but there isn't a regular maintainer and these patches are for the benefit of the powernv machine type. This pull request supersedes my 2017-04-26 pull request. This new set fixes a bug in one of the aforementioned IPMI patches which caused clang sanitizer failures (and may have crashed on some libc / host versions). # gpg: Signature made Wed 26 Apr 2017 07:58:10 BST # gpg: using RSA key 0x6C38CACA20D9B392 # gpg: Good signature from "David Gibson <david@gibson.dropbear.id.au>" # gpg: aka "David Gibson (Red Hat) <dgibson@redhat.com>" # gpg: aka "David Gibson (ozlabs.org) <dgibson@ozlabs.org>" # gpg: aka "David Gibson (kernel.org) <dwg@kernel.org>" # Primary key fingerprint: 75F4 6586 AE61 A66C C44E 87DC 6C38 CACA 20D9 B392 * remotes/dgibson/tags/ppc-for-2.10-20170426: (48 commits) MAINTAINERS: Remove myself from e500 target/ppc: Style fixes e500,book3s: mfspr 259: Register mapped/aliased SPRG3 user read target/ppc: Flush TLB on write to PIDR spapr-cpu-core: Release ICPState object during CPU unrealization ppc/pnv: generate an OEM SEL event on shutdown ppc/pnv: add initial IPMI sensors for the BMC simulator ppc/pnv: populate device tree for IPMI BT devices ppc/pnv: populate device tree for serial devices ppc/pnv: populate device tree for RTC devices ppc/pnv: scan ISA bus to populate device tree ppc/pnv: enable only one LPC bus ppc/pnv: Add support for POWER8+ LPC Controller spapr: remove the 'nr_servers' field from the machine target/ppc: Fix size of struct PPCElfPrstatus ipmi: introduce an ipmi_bmc_gen_event() API ipmi: introduce an ipmi_bmc_sdr_find() API ipmi: provide support for FRUs ipmi: use a file to load SDRs ppc: add IPMI support ...
