2023-05-30meson: Split test for __int128_t type from __int128_t arithmeticRichard Henderson
Older versions of clang have missing runtime functions for arithmetic with -fsanitize=undefined (see 464e3671f9d5c), so we cannot use __int128_t for implementing Int128. But __int128_t is present, data movement works, and it can be used for atomic128. Probe for both CONFIG_INT128_TYPE and CONFIG_INT128, adjust qemu/int128.h to define Int128Alias if CONFIG_INT128_TYPE, and adjust the meson probe for atomics to use has_int128_type.

2023-05-30aio: remove aio_disable_external() APIStefan Hajnoczi
All callers now pass is_external=false to aio_set_fd_handler() and aio_set_event_notifier(). The aio_disable_external() API that temporarily disables fd handlers that were registered is_external=true is therefore dead code. Remove aio_disable_external(), aio_enable_external(), and the is_external arguments to aio_set_fd_handler() and aio_set_event_notifier(). The entire test-fdmon-epoll test is removed because its sole purpose was testing aio_disable_external().

2023-05-30virtio-scsi: implement BlockDevOps->drained_begin()Stefan Hajnoczi
The virtio-scsi Host Bus Adapter provides access to devices on a SCSI bus. Those SCSI devices typically have a BlockBackend. When the BlockBackend enters a drained section, the SCSI device must temporarily stop submitting new I/O requests. Implement this behavior by temporarily stopping virtio-scsi virtqueue processing when one of the SCSI devices enters a drained section. The new scsi_device_drained_begin() API allows scsi-disk to message the virtio-scsi HBA. scsi_device_drained_begin() uses a drain counter so that multiple SCSI devices can have overlapping drained sections. The HBA only sees one pair of .drained_begin/end() calls. After this commit, virtio-scsi no longer depends on hw/virtio's ioeventfd aio_set_event_notifier(is_external=true). This commit is a step towards removing the aio_disable_external() API.

2023-05-30block: drain from main loop thread in bdrv_co_yield_to_drain()Stefan Hajnoczi
For simplicity, always run BlockDevOps .drained_begin/end/poll() callbacks in the main loop thread. This makes it easier to implement the callbacks and avoids extra locks. Move the function pointer declarations from the I/O Code section to the Global State section for BlockDevOps, BdrvChildClass, and BlockDriver. Narrow IO_OR_GS_CODE() to GLOBAL_STATE_CODE() where appropriate. The test-bdrv-drain test case calls bdrv_drain() from an IOThread. This is now only allowed from coroutine context, so update the test case to run in a coroutine.

2023-05-30block/export: wait for vhost-user-blk requests when drainingStefan Hajnoczi
Each vhost-user-blk request runs in a coroutine. When the BlockBackend enters a drained section we need to enter a quiescent state. Currently any in-flight requests race with bdrv_drained_begin() because it is unaware of vhost-user-blk requests. When blk_co_preadv/pwritev()/etc returns it wakes the bdrv_drained_begin() thread but vhost-user-blk request processing has not yet finished. The request coroutine continues executing while the main loop thread thinks it is in a drained section. One example where this is unsafe is for blk_set_aio_context() where bdrv_drained_begin() is called before .aio_context_detached() and .aio_context_attach(). If request coroutines are still running after bdrv_drained_begin(), then the AioContext could change underneath them and they race with new requests processed in the new AioContext. This could lead to virtqueue corruption, for example. (This example is theoretical, I came across this while reading the code and have not tried to reproduce it.) It's easy to make bdrv_drained_begin() wait for in-flight requests: add a .drained_poll() callback that checks the VuServer's in-flight counter. VuServer just needs an API that returns true when there are requests in flight. The in-flight counter needs to be atomic.

2023-05-30util/vhost-user-server: rename refcount to in_flight counterStefan Hajnoczi
The VuServer object has a refcount field and ref/unref APIs. The name is confusing because it's actually an in-flight request counter instead of a refcount. Normally a refcount destroys the object upon reaching zero. The VuServer counter is used to wake up the vhost-user coroutine when there are no more requests. Avoid confusing by renaming refcount and ref/unref to in_flight and inc/dec.

2023-05-30block-coroutine-wrapper: Take AioContext lock in no_co_wrappersKevin Wolf
All of the functions that currently take a BlockDriverState, BdrvChild or BlockBackend as their first parameter expect the associated AioContext to be locked when they are called. In the case of no_co_wrappers, they are called from bottom halves directly in the main loop, so no other caller can be expected to take the lock for them. This can result in assertion failures because a lock that isn't taken is released in nested event loops. Looking at the first parameter is already done by co_wrappers to decide where the coroutine should run, so doing the same in no_co_wrappers is only consistent. Take the lock in the generated bottom halves to fix the problem.

Parse stage-2 configuration from STE and populate it in SMMUS2Cfg. Validity of field values are checked when possible. Only AA64 tables are supported and Small Translation Tables (STT) are not supported. According to SMMUv3 UM(IHI0070E) "5.2 Stream Table Entry": All fields with an S2 prefix (with the exception of S2VMID) are IGNORED when stage-2 bypasses translation (Config[1] == 0). Which means that VMID can be used(for TLB tagging) even if stage-2 is bypassed, so we parse it unconditionally when S2P exists. Otherwise it is set to -1.(only S1P) As stall is not supported, if S2S is set the translation would abort. For S2R, we reuse the same code used for stage-1 with flag record_faults. However when nested translation is supported we would need to separate stage-1 and stage-2 faults. Fix wrong shift in STE_S2HD, STE_S2HA, STE_S2S.

2023-05-28spapr: Add SPAPR_CAP_AIL_MODE_3 for AIL mode 3 support for H_SET_MODE hcallNicholas Piggin
The behaviour of the Address Translation Mode on Interrupt resource is not consistently supported by all CPU versions or all KVM versions: KVM HV does not support mode 2, and does not support mode 3 on POWER7 or early POWER9 processesors. KVM PR only supports mode 0. TCG supports all modes (0, 2, 3) on CPUs with support for the corresonding LPCR[AIL] mode. This leads to inconsistencies in guest behaviour and could cause problems migrating guests. This was not noticable for Linux guests for a long time because the kernel only uses modes 0 and 3, and it used to consider AIL-3 to be advisory in that it would always keep the AIL-0 vectors around, so it did not matter whether or not interrupts were delivered according to the AIL mode. Recent Linux guests depend on AIL mode 3 working as specified in order to support the SCV facility interrupt. If AIL-3 can not be provided, then H_SET_MODE must return an error to Linux so it can disable the SCV facility (failure to do so can lead to userspace being able to crash the guest kernel). Add the ail-mode-3 capability to specify that AIL-3 is supported. AIL-0 is implied as the baseline, and AIL-2 is no longer supported by spapr. AIL-2 is not known to be used by any software, but support in TCG could be restored with an ail-mode-2 capability quite easily if a regression is reported. Modify the H_SET_MODE Address Translation Mode on Interrupt resource handler to check capabilities and correctly return error if not supported. KVM has a cap to advertise support for AIL-3.

2023-05-28ui/cursor: make width/height unsigned 16-bit integerMauro Matteo Cascella
Although not actually exploitable at the moment, a negative width/height could make datasize wrap around and potentially lead to buffer overflow. Since there is no reason a negative width/height is ever appropriate, modify QEMUCursor struct and cursor_alloc prototype to accept uint16_t. This protects us against accidentally introducing future bugs.

Since commit abe34282 ("win32: avoid mixing SOCKET and file descriptor space"), we set HANDLE_FLAG_PROTECT_FROM_CLOSE on the socket FD, to prevent closing the HANDLE with CloseHandle. This raises an exception which under gdb is fatal, and qemu exits. Let's catch the expected error instead. Note: this appears to work, but the mingw64 macro is not well documented or tested, and it's not obvious how it is meant to be used.

Add an option for hostmem-file to start the memory object at an offset into the target file. This is useful if multiple memory objects reside inside the same target file, such as a device node. In particular, it's useful to map guest memory directly into /dev/mem for experimentation. To make this work consistently, also fix up all places in QEMU that expect fd offsets to be 0.
