virt: acrn: Replace obsolete memalign() with posix_memalign() memalign() is obsolete according to its manpage. Replace memalign() with posix_memalign() and remove malloc.h include that was there for memalign(). As a pointer is passed into posix_memalign(), initialize *p to NULL to silence a warning about the function's return value being used as uninitialized (which is not valid anyway because the error is properly checked before p is returned).

treewide: remove editor modelines and cruft The section "19) Editor modelines and other cruft" in Documentation/process/coding-style.rst clearly says, "Do not include any of these in source files." I recently receive a patch to explicitly add a new one. Let's do treewide cleanups, otherwise some people follow the existing code and attempt to upstream their favoriate editor setups. It is even nicer if scripts/checkpatch.pl can check it. If we like to impose coding style in an editor-independent manner, I think editorconfig (patch [1]) is a saner solution.

tracing: Verify event formats that have "%*p.." stable inclusion from stable-6.6.89 commit 4d11fac941d83509be4e6a21038281d6d96da50c category: bugfix issue: #IC6IH3 CVE: NA Signed-off-by: zyf1116 <zhouyongfei3@huawei.com> --------------------------------------- [ Upstream commit ea8d7647f9ddf1f81e2027ed305299797299aa03 ] The trace event verifier checks the formats of trace events to make sure that they do not point at memory that is not in the trace event itself or in data that will never be freed. If an event references data that was allocated when the event triggered and that same data is freed before the event is read, then the kernel can crash by reading freed memory. The verifier runs at boot up (or module load) and scans the print formats of the events and checks their arguments to make sure that dereferenced pointers are safe. If the format uses "%*p.." the verifier will ignore it, and that could be dangerous. Cover this case as well. Also add to the sample code a use case of "%*pbl".

kbuild: introduce hostprogs-always-y and userprogs-always-y To build host programs, you need to add the program names to 'hostprogs' to use the necessary build rule, but it is not enough to build them because there is no dependency. There are two types of host programs: built as the prerequisite of another (e.g. gen_crc32table in lib/Makefile), or always built when Kbuild visits the Makefile (e.g. genksyms in scripts/genksyms/Makefile). The latter is typical in Makefiles under scripts/, which contains host programs globally used during the kernel build. To build them, you need to add them to both 'hostprogs' and 'always-y'. This commit adds hostprogs-always-y as a shorthand. The same applies to user programs. net/bpfilter/Makefile builds bpfilter_umh on demand, hence always-y is unneeded. In contrast, programs under samples/ are added to both 'userprogs' and 'always-y' so they are always built when Kbuild visits the Makefiles. userprogs-always-y works as a shorthand.

vfio/mtty: Overhaul mtty interrupt handling [ Upstream commit 293fbc28818135743f54d46c418ede3e4a20a742 ] The mtty driver does not currently conform to the vfio SET_IRQS uAPI. For example, it claims to support mask and unmask of INTx, but actually does nothing. It claims to support AUTOMASK for INTx, but doesn't. It fails to teardown eventfds under the full semantics specified by the SET_IRQS ioctl. It also fails to teardown eventfds when the device is closed, leading to memory leaks. It claims to support the request IRQ, but doesn't. Fix all these. A side effect of this is that QEMU will now report a warning: vfio <uuid>: Failed to set up UNMASK eventfd signaling for interrupt \ INTX-0: VFIO_DEVICE_SET_IRQS failure: Inappropriate ioctl for device The fact is that the unmask eventfd was never supported but quietly failed. mtty never honored the AUTOMASK behavior, therefore there was nothing to unmask. QEMU is verbose about the failure, but properly falls back to userspace unmasking. Fixes: 9d1a546c53b4 ("docs: Sample driver to demonstrate how to use Mediated device framework.")
