2020-06-26pmu: fix duplicate autopoll mask variableMark Cave-Ayland
It seems that during the initial work to introduce the via-pmu ADB support a duplicate autopoll mask variable was accidentally left in place. Remove the duplicate autopoll_mask variable and switch everything over to use adb_poll_mask instead.

2020-06-26adb: fix adb-mouse read length and revert disable-reg3-direct-writes workaroundMark Cave-Ayland
Commit 84051eb400 "adb: add property to disable direct reg 3 writes" introduced a workaround for spurious writes to ADB register 3 when MacOS 9 enables autopoll on the mouse device. Further analysis shows that the problem is that only a partial request is sent, and since the len parameter is ignored then stale data from the previous request is used causing the incorrect address assignment. Remove the disable-reg3-direct-writes workaround and instead check the length parameter when the write is attempted, discarding the invalid request.

2020-06-26ppc/pnv: Silence missing BMC warning with qtestGreg Kurz
The device introspect test in qtest emits some warnings with the the pnv machine types during the "nodefaults" phase: TEST check-qtest-ppc64: tests/qtest/device-introspect-test qemu-system-ppc64: warning: machine has no BMC device. Use '-device ipmi-bmc-sim,id=bmc0 -device isa-ipmi-bt,bmc=bmc0,irq=10' to define one qemu-system-ppc64: warning: machine has no BMC device. Use '-device ipmi-bmc-sim,id=bmc0 -device isa-ipmi-bt,bmc=bmc0,irq=10' to define one qemu-system-ppc64: warning: machine has no BMC device. Use '-device ipmi-bmc-sim,id=bmc0 -device isa-ipmi-bt,bmc=bmc0,irq=10' to define one This is expected since the pnv machine doesn't create the internal BMC simulator fallback when "-nodefaults" is passed on the command line, but these warnings appear in ci logs and confuse people. Not having a BMC isn't recommended but it is still a supported configuration, so a straightforward fix is to just silent this warning when qtest is enabled.

2020-06-24Stop vhost-user sending uninitialized mmap_offsetsRaphael Norwitz
Prior to this change, the vhost_user_fill_msg_region function filled out all elements of the VhostUserMemoryRegion struct except the mmap_offset. This function is often called on uninitialized structs, which are then copied into VHOST_USER_SET_MEM_TABLE and VHOST_USER_ADD/REM_MEM_REG messages. In some cases, where the mmap_offset was not needed, it was left uninitialized, causing QEMU to send the backend uninitialized data, which Coverity flagged as a series of issues. This change augments the vhost_user_fill_msg_region API, adding a mmap_offset paramenter, forcing the caller to initialize mmap_offset.

2020-06-23block/nvme: support nested aio_poll()Stefan Hajnoczi
QEMU block drivers are supposed to support aio_poll() from I/O completion callback functions. This means completion processing must be re-entrant. The standard approach is to schedule a BH during completion processing and cancel it at the end of processing. If aio_poll() is invoked by a callback function then the BH will run. The BH continues the suspended completion processing. All of this means that request A's cb() can synchronously wait for request B to complete. Previously the nvme block driver would hang because it didn't process completions from nested aio_poll().

2020-06-23block/nvme: switch to a NVMeRequest freelistStefan Hajnoczi
There are three issues with the current NVMeRequest->busy field: 1. The busy field is accidentally accessed outside q->lock when request submission fails. 2. Waiters on free_req_queue are not woken when a request is returned early due to submission failure. 2. Finding a free request involves scanning all requests. This makes request submission O(n^2). Switch to an O(1) freelist that is always accessed under the lock. Also differentiate between NVME_QUEUE_SIZE, the actual SQ/CQ size, and NVME_NUM_REQS, the number of usable requests. This makes the code simpler than using NVME_QUEUE_SIZE everywhere and having to keep in mind that one slot is reserved.

2020-06-23block/nvme: don't access CQE after moving cq.headStefan Hajnoczi
Do not access a CQE after incrementing q->cq.head and releasing q->lock. It is unlikely that this causes problems in practice but it's a latent bug. The reason why it should be safe at the moment is that completion processing is not re-entrant and the CQ doorbell isn't written until the end of nvme_process_completion(). Make this change now because QEMU expects completion processing to be re-entrant and later patches will do that.

2020-06-23check-block: enable iotests with SafeStackDaniele Buono
SafeStack is a stack protection technique implemented in llvm. It is enabled with a -fsanitize flag. iotests are currently disabled when any -fsanitize option is used, because such options tend to produce additional warnings and false positives. While common -fsanitize options are used to verify the code and not added in production, SafeStack's main use is in production environments to protect against stack smashing. Since SafeStack does not print any warning or false positive, enable iotests when SafeStack is the only -fsanitize option used. This is likely going to be a production binary and we want to make sure it works correctly.

This patch adds a flag to enable/disable the SafeStack instrumentation provided by LLVM. On enable, make sure that the compiler supports the flags, and that we are using the proper coroutine implementation (coroutine-ucontext). On disable, explicitly disable the option if it was enabled by default. While SafeStack is supported only on Linux, NetBSD, FreeBSD and macOS, we are not checking for the O.S. since this is already done by LLVM.

2020-06-23coroutine: add check for SafeStack in sigaltstackDaniele Buono
Current implementation of LLVM's SafeStack is not compatible with code that uses an alternate stack created with sigaltstack(). Since coroutine-sigaltstack relies on sigaltstack(), it is not compatible with SafeStack. The resulting binary is incorrect, with different coroutines sharing the same unsafe stack and producing undefined behavior at runtime. In the future LLVM may provide a SafeStack implementation compatible with sigaltstack(). In the meantime, if SafeStack is desired, the coroutine implementation from coroutine-ucontext should be used. As a safety check, add a control in coroutine-sigaltstack to throw a preprocessor #error if SafeStack is enabled and we are trying to use coroutine-sigaltstack to implement coroutines.

2020-06-23coroutine: support SafeStack in ucontext backendDaniele Buono
LLVM's SafeStack instrumentation does not yet support programs that make use of the APIs in ucontext.h With the current implementation of coroutine-ucontext, the resulting binary is incorrect, with different coroutines sharing the same unsafe stack and producing undefined behavior at runtime. This fix allocates an additional unsafe stack area for each coroutine, and sets the new unsafe stack pointer before calling swapcontext() in qemu_coroutine_new. This is the only place where the pointer needs to be manually updated, since sigsetjmp/siglongjmp are already instrumented by LLVM to properly support SafeStack. The additional stack is then freed in qemu_coroutine_delete.
