User-space is allowed to submit any property in an async flip as long as the value doesn't change. However we missed one case: as things stand, the kernel rejects no-op FB_ID changes on non-primary planes. Fix this by changing the conditional and skipping drm_atomic_check_prop_changes() only for FB_ID on the primary plane (instead of skipping for FB_ID on any plane).

The test here creates an sg table, but never maps it, when we get to drm_gem_shmem_free, the helper tries to unmap and this causes warnings on some platforms and debug kernels.

When a buffer is evicted for memory pressure or TTM evict all, the placement is set to the eviction domain, this means the buffer never gets revalidated on the next exec to the correct domain. I think this should be fine to use the initial domain from the object creation, as least with VM_BIND this won't change after init so this should be the correct answer.

Power up the ASTDP connector for connection status detection if the connector is not active. Keep it powered if a display is attached. This fixes a bug where the connector does not come back after disconnecting the display. The encoder's atomic_disable turns off power on the physical connector. Further HPD reads will fail, thus preventing the driver from detecting re-connected displays. For connectors that are actively used, only test the HPD flag without touching power.

TAP version 13 1..11 # Testing heap: system # ======================================= # Testing allocation and importing: ok 1 # SKIP Could not open vgem -1 The problem is that we use the DRM_IOCTL_VERSION ioctl to query the driver version information but leave the name field a non-null-terminated string. Terminate it properly to actually test against the vgem device. While at it, let's check the length of the driver name is exactly 4 bytes and return early otherwise (in case there is a name like "vgemfoo" that gets converted to "vgem\0" unexpectedly).

This simplifies the min_t() and max_t() macros by no longer making them work in the context of a C constant expression. That means that you can no longer use them for static initializers or for array sizes in type definitions, but there were only a couple of such uses, and all of them were converted (famous last words) to use MIN_T/MAX_T instead.

Commit 3a7e02c0 ("minmax: avoid overly complicated constant expressions in VM code") added the simpler MIN_T/MAX_T macros in order to avoid some excessive expansion from the rather complicated regular min/max macros. The complexity of those macros stems from two issues: (a) trying to use them in situations that require a C constant expression (in static initializers and for array sizes) (b) the type sanity checking and MIN_T/MAX_T avoids both of these issues. Now, in the whole (long) discussion about all this, it was pointed out that the whole type sanity checking is entirely unnecessary for min_t/max_t which get a fixed type that the comparison is done in. But that still leaves min_t/max_t unnecessarily complicated due to worries about the C constant expression case. However, it turns out that there really aren't very many cases that use min_t/max_t for this, and we can just force-convert those. This does exactly that. Which in turn will then allow for much simpler implementations of min_t()/max_t(). All the usual "macros in all upper case will evaluate the arguments multiple times" rules apply. We should do all the same things for the regular min/max() vs MIN/MAX() cases, but that has the added complexity of various drivers defining their own local versions of MIN/MAX, so that needs another level of fixes first.

After a recent change in clang to stop consuming all instances of '-S' and '-c' [1], the stack protector scripts break due to the kernel's use of -Werror=unused-command-line-argument to catch cases where flags are not being properly consumed by the compiler driver: $ echo | clang -o - -x c - -S -c -Werror=unused-command-line-argument clang: error: argument unused during compilation: '-c' [-Werror,-Wunused-command-line-argument] This results in CONFIG_STACKPROTECTOR getting disabled because CONFIG_CC_HAS_SANE_STACKPROTECTOR is no longer set. '-c' and '-S' both instruct the compiler to stop at different stages of the pipeline ('-S' after compiling, '-c' after assembling), so having them present together in the same command makes little sense. In this case, the test wants to stop before assembling because it is looking at the textual assembly output of the compiler for either '%fs' or '%gs', so remove '-c' from the list of arguments to resolve the error. All versions of GCC continue to work after this change, along with versions of clang that do or do not contain the change mentioned above.

Pull vfs fixes from Christian Brauner: "This contains two fixes for this merge window: VFS: - I noticed that it is possible for a privileged user to mount most filesystems with a non-initial user namespace in sb->s_user_ns. When fsopen() is called in a non-init namespace the caller's namespace is recorded in fs_context->user_ns. If the returned file descriptor is then passed to a process privileged in init_user_ns, that process can call fsconfig(fd_fs, FSCONFIG_CMD_CREATE*), creating a new superblock with sb->s_user_ns set to the namespace of the process which called fsopen(). This is problematic as only filesystems that raise FS_USERNS_MOUNT are known to be able to support a non-initial s_user_ns. Others may suffer security issues, on-disk corruption or outright crash the kernel. Prevent that by restricting such delegation to filesystems that allow FS_USERNS_MOUNT. Note, that this delegation requires a privileged process to actually create the superblock so either the privileged process is cooperaing or someone must have tricked a privileged process into operating on a fscontext file descriptor whose origin it doesn't know (a stupid idea). The bug dates back to about 5 years afaict. Misc: - Fix hostfs parsing when the mount request comes in via the legacy mount api. In the legacy mount api hostfs allows to specify the host directory mount without any key. Restore that behavior" * tag 'vfs-6.11-rc1.fixes.3' of git://git.kernel.org/pub/scm/linux/kernel/git/vfs/vfs: hostfs: fix the host directory parse when mounting. fs: don't allow non-init s_user_ns for filesystems without FS_USERNS_MOUNT

Pull Rust updates from Miguel Ojeda: "The highlight is the establishment of a minimum version for the Rust toolchain, including 'rustc' (and bundled tools) and 'bindgen'. The initial minimum will be the pinned version we currently have, i.e. we are just widening the allowed versions. That covers three stable Rust releases: 1.78.0, 1.79.0, 1.80.0 (getting released tomorrow), plus beta, plus nightly. This should already be enough for kernel developers in distributions that provide recent Rust compiler versions routinely, such as Arch Linux, Debian Unstable (outside the freeze period), Fedora Linux, Gentoo Linux (especially the testing channel), Nix (unstable) and openSUSE Slowroll and Tumbleweed. In addition, the kernel is now being built-tested by Rust's pre-merge CI. That is, every change that is attempting to land into the Rust compiler is tested against the kernel, and it is merged only if it passes. Similarly, the bindgen tool has agreed to build the kernel in their CI too. Thus, with the pre-merge CI in place, both projects hope to avoid unintentional changes to Rust that break the kernel. This means that, in general, apart from intentional changes on their side (that we will need to workaround conditionally on our side), the upcoming Rust compiler versions should generally work. In addition, the Rust project has proposed getting the kernel into stable Rust (at least solving the main blockers) as one of its three flagship goals for 2024H2 [1]. I would like to thank Niko, Sid, Emilio et al. for their help promoting the collaboration between Rust and the kernel. Toolchain and infrastructure: - Support several Rust toolchain versions. - Support several bindgen versions. - Remove 'cargo' requirement and simplify 'rusttest', thanks to 'alloc' having been dropped last cycle. - Provide proper error reporting for the 'rust-analyzer' target. 'kernel' crate: - Add 'uaccess' module with a safe userspace pointers abstraction. - Add 'page' module with a 'struct page' abstraction. - Support more complex generics in workqueue's 'impl_has_work!' macro. 'macros' crate: - Add 'firmware' field support to the 'module!' macro. - Improve 'module!' macro documentation. Documentation: - Provide instructions on what packages should be installed to build the kernel in some popular Linux distributions. - Introduce the new kernel.org LLVM+Rust toolchains. - Explain '#[no_std]'.

Merge tag 'firewire-fixes-6.11-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/ieee1394/linux1394 Pull firewire fixes from Takashi Sakamoto: "The recent integration of compiler collections introduced the technology to check flexible array length at runtime by providing proper annotations. In v6.10 kernel, a patch was merged into firewire subsystem to utilize it, however the annotation was inadequate. There is also the related change for the flexible array in sound subsystem, but it causes a regression where the data in the payload of isochronous packet is incorrect for some devices. These bugs are now fixed" * tag 'firewire-fixes-6.11-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/ieee1394/linux1394: ALSA: firewire-lib: fix wrong value as length of header for CIP_NO_HEADER case Revert "firewire: Annotate struct fw_iso_packet with __counted_by()"
