2023-07-15linux-user/arm: Do not allocate a commpage at all for M-profile CPUsPhilippe Mathieu-Daudé
Since commit fbd3c4cff6 ("linux-user/arm: Mark the commpage executable") executing bare-metal (linked with rdimon.specs) cortex-M code fails as: $ qemu-arm -cpu cortex-m3 ~/hello.exe.m3 qemu-arm: ../../accel/tcg/user-exec.c:492: page_set_flags: Assertion `last <= GUEST_ADDR_MAX' failed. Aborted (core dumped) Commit 4f5c67f8df ("linux-user/arm: Take more care allocating commpage") already took care of not allocating a commpage for M-profile CPUs, however it had to be reverted as commit 6cda41daa2. Re-introduce the M-profile fix from commit 4f5c67f8df.

2023-07-15linux-user/syscall: Implement execve without execveatPierrick Bouvier
Support for execveat syscall was implemented in 55bbe4 and is available since QEMU 8.0.0. It relies on host execveat, which is widely available on most of Linux kernels today. However, this change breaks qemu-user self emulation, if "host" qemu version is less than 8.0.0. Indeed, it does not implement yet execveat. This strange use case happens with most of distribution today having binfmt support. With a concrete failing example: $ qemu-x86_64-7.2 qemu-x86_64-8.0 /bin/bash -c /bin/ls /bin/bash: line 1: /bin/ls: Function not implemented -> not implemented means execve returned ENOSYS qemu-user-static 7.2 and 8.0 can be conveniently grabbed from debian packages qemu-user-static* [1]. One usage of this is running wine-arm64 from linux-x64 (details [2]). This is by updating qemu embedded in docker image that we ran into this issue. The solution to update host qemu is not always possible. Either it's complicated or ask you to recompile it, or simply is not accessible (GitLab CI, GitHub Actions). Thus, it could be worth to implement execve without relying on execveat, which is the goal of this patch. This patch was tested with example presented in this commit message.

2023-07-14scsi: fetch unit attention when creating the requestStefano Garzarella
Commit 1880ad4f4e ("virtio-scsi: Batched prepare for cmd reqs") split calls to scsi_req_new() and scsi_req_enqueue() in the virtio-scsi device. No ill effects were observed until commit 8cc5583abe ("virtio-scsi: Send "REPORTED LUNS CHANGED" sense data upon disk hotplug events") added a unit attention that was easy to trigger with device hotplug and hot-unplug. Because the two calls were separated, all requests in the batch were prepared calling scsi_req_new() to report a sense. The first one submitted would report the right sense and reset it to NO_SENSE, while the others reported CHECK_CONDITION with no sense data. This caused SCSI errors in Linux. To solve this issue, let's fetch the unit attention as early as possible when we prepare the request, so that only the first request in the batch will use the unit attention SCSIReqOps and the others will not report CHECK CONDITION.
