2022-01-28bsd-user/signal.c: Add si_type argument to queue_signalWarner Losh
Mirror the linux-user practice and add a si_type argument to queue signal. This will be transported as the upper 8 bits in the si_type element of siginfo so that we know what bits of the structure are valid and so we can properly implement host_to_target_siginfo_noswap and tswap_siginfo. Adapt the one caller of queue_signal to the new interface. Use all the same names as Linux (except _RT which we don't treat differently, unlike Linux), though some are unused. Place this into signal-common.h since that's a better place given bsd-user's structure. Move prototype of queue_signal to signal-common.h to mirror linux-user's location.

2022-01-27xen-mapcache: Avoid entry->lock overflowRoss Lagerwall
In some cases, a particular mapcache entry may be mapped 256 times causing the lock field to wrap to 0. For example, this may happen when using emulated NVME and the guest submits a large scatter-gather write. At this point, the entry map be remapped causing QEMU to write the wrong data or crash (since remap is not atomic). Avoid this overflow by increasing the lock field to a uint32_t and also detect it and abort rather than continuing regardless.

2022-01-27xen-hvm: Allow disabling buffer_io_timerJason Andryuk
commit f37f29d31488 "xen: slightly simplify bufioreq handling" hard coded setting req.count = 1 during initial field setup before the main loop. This missed a subtlety that an early exit from the loop when there are no ioreqs to process, would have req.count == 0 for the return value. handle_buffered_io() would then remove state->buffered_io_timer. Instead handle_buffered_iopage() is basically always returning true and handle_buffered_io() always re-setting the timer. Restore the disabling of the timer by introducing a new handled_ioreq boolean and use as the return value. The named variable will more clearly show the intent of the code.

2022-01-27qapi: generate trace events by defaultVladimir Sementsov-Ogievskiy
We don't generate trace events for tests/ and qga/ because that it is not simple and not necessary. We have corresponding comments in both tests/meson.build and qga/meson.build. Still to not miss possible future qapi code generation call, and not to forget to enable trace events generation, let's enable it by default. So, turn option --gen-trace into opposite --no-trace-events and use new option only in tests/ and qga/ where we already have good comments why we don't generate trace events code. Note that this commit enables trace-events generation for qapi-gen.py call from tests/qapi-schema/meson.build and storage-daemon/meson.build. Still, both are kind of noop: tests/qapi-schema/ doesn't seem to generate any QMP command code and no .trace-events files anyway, storage-daemon/ uses common QMP command implementations and just generate empty .trace-events Signed-off-by: Vladimir Sementsov-Ogievskiy <vsementsov@virtuozzo.com> Reviewed-by: Stefan Hajnoczi <stefanha@redhat.com> Message-Id: <20220126161130.3240892-8-vsementsov@virtuozzo.com> Reviewed-by: Markus Armbruster <armbru@redhat.com> Signed-off-by: Markus Armbruster <armbru@redhat.com>
2022-01-27meson: document why we don't generate trace events for tests/ and qga/Vladimir Sementsov-Ogievskiy
Making trace generation work for tests/ and qga/ would involve some Meson hackery to ensure we generate the trace-events files before trace-tool uses them. Since we don't actually support tracing there anyway, we bypass that problem. Let's add corresponding comments.

Previous commits enabled trace events generation for most of QAPI generated code (except for tests/ and qga/). Let's update documentation to illustrate it.

2022-01-27exec/cpu: Make host pages variables / macros 'target agnostic'Philippe Mathieu-Daudé
"host" pages are related to the *host* not the *target*, thus the qemu_host_page_size / qemu_host_page_mask variables and the HOST_PAGE_ALIGN() / REAL_HOST_PAGE_ALIGN() macros can be moved to "exec/cpu-common.h" which is target agnostic.
