2025-01-04crypto: keywrap - remove unused keywrap algorithmEric Biggers
The keywrap (kw) algorithm has no in-tree user. It has never had an in-tree user, and the patch that added it provided no justification for its inclusion. Even use of it via AF_ALG is impossible, as it uses a weird calling convention where part of the ciphertext is returned via the IV buffer, which is not returned to userspace in AF_ALG. It's also unclear whether any new code in the kernel that does key wrapping would actually use this algorithm. It is controversial in the cryptographic community due to having no clearly stated security goal, no security proof, poor performance, and only a 64-bit auth tag. Later work (https://eprint.iacr.org/2006/221) suggested that the goal is deterministic authenticated encryption. But there are now more modern algorithms for this, and this is not the same as key wrapping, for which a regular AEAD such as AES-GCM usually can be (and is) used instead. Therefore, remove this unused code. There were several special cases for this algorithm in the self-tests, due to its weird calling convention. Remove those too.

2025-01-04crypto: vmac - remove unused VMAC algorithmEric Biggers
Remove the vmac64 template, as it has no known users. It also continues to have longstanding bugs such as alignment violations (see https://lore.kernel.org/r/20241226134847.6690-1-evepolonium@gmail.com/). This code was added in 2009 by commit f1939f7c5645 ("crypto: vmac - New hash algorithm for intel_txt support"). Based on the mention of intel_txt support in the commit title, it seems it was added as a prerequisite for the contemporaneous patch "intel_txt: add s3 userspace memory integrity verification" (https://lore.kernel.org/r/4ABF2B50.6070106@intel.com/). In the design proposed by that patch, when an Intel Trusted Execution Technology (TXT) enabled system resumed from suspend, the "tboot" trusted executable launched the Linux kernel without verifying userspace memory, and then the Linux kernel used VMAC to verify userspace memory. However, that patch was never merged, as reviewers had objected to the design. It was later reworked into commit 4bd96a7a8185 ("x86, tboot: Add support for S3 memory integrity protection") which made tboot verify the memory instead. Thus the VMAC support in Linux was never used. No in-tree user has appeared since then, other than potentially the usual components that allow specifying arbitrary hash algorithms by name, namely AF_ALG and dm-integrity. However there are no indications that VMAC is being used with these components. Debian Code Search and web searches for "vmac64" (the actual algorithm name) do not return any results other than the kernel itself, suggesting that it does not appear in any other code or documentation. Explicitly grepping the source code of the usual suspects (libell, iwd, cryptsetup) finds no matches either. Before 2018, the vmac code was also completely broken due to using a hardcoded nonce and the wrong endianness for the MAC. It was then fixed by commit ed331adab35b ("crypto: vmac - add nonced version with big endian digest") and commit 0917b873127c ("crypto: vmac - remove insecure version with hardcoded nonce"). These were intentionally breaking changes that changed all the computed MAC values as well as the algorithm name ("vmac" to "vmac64"). No complaints were ever received about these breaking changes, strongly suggesting the absence of users. The reason I had put some effort into fixing this code in 2018 is because it was used by an out-of-tree driver. But if it is still needed in that particular out-of-tree driver, the code can be carried in that driver instead. There is no need to carry it upstream.

2024-12-09m68k: Use kernel's generic muldi3 libgcc functionGreg Ungerer
Use the kernels own generic lib/muldi3.c implementation of muldi3 for 68K machines. Some 68K CPUs support 64bit multiplies so move the arch specific umul_ppmm() macro into a header file that is included by lib/muldi3.c. That way it can take advantage of the single instruction when available. There does not appear to be any existing mechanism for the generic lib/muldi3.c code to pick up an external arch definition of umul_ppmm(). Create an arch specific libgcc.h that can optionally be included by the system include/linux/libgcc.h to allow for this. Somewhat oddly there is also a similar definition of umul_ppmm() in the non-architecture code in lib/crypto/mpi/longlong.h for a wide range or machines. Its presence ends up complicating the include setup and means not being able to use something like compiler.h instead. Actually there is a few other defines of umul_ppmm() macros spread around in various architectures, but not directly usable for the m68k case.

2024-11-06fs/xattr: add *at family syscallsChristian Göttsche
Add the four syscalls setxattrat(), getxattrat(), listxattrat() and removexattrat(). Those can be used to operate on extended attributes, especially security related ones, either relative to a pinned directory or on a file descriptor without read access, avoiding a /proc/<pid>/fd/<fd> detour, requiring a mounted procfs. One use case will be setfiles(8) setting SELinux file contexts ("security.selinux") without race conditions and without a file descriptor opened with read access requiring SELinux read permission. Use the do_{name}at() pattern from fs/open.c. Pass the value of the extended attribute, its length, and for setxattrat(2) the command (XATTR_CREATE or XATTR_REPLACE) via an added struct xattr_args to not exceed six syscall arguments and not merging the AT_* and XATTR_* flags.

2024-07-10clone3: drop __ARCH_WANT_SYS_CLONE3 macroArnd Bergmann
When clone3() was introduced, it was not obvious how each architecture deals with setting up the stack and keeping the register contents in a fork()-like system call, so this was left for the architecture maintainers to implement, with __ARCH_WANT_SYS_CLONE3 defined by those that already implement it. Five years later, we still have a few architectures left that are missing clone3(), and the macro keeps getting in the way as it's fundamentally different from all the other __ARCH_WANT_SYS_* macros that are meant to provide backwards-compatibility with applications using older syscalls that are no longer provided by default. Address this by reversing the polarity of the macro, adding an __ARCH_BROKEN_SYS_CLONE3 macro to all architectures that don't already provide the syscall, and remove __ARCH_WANT_SYS_CLONE3 from all the other ones.

2024-07-01m68k: atari: Fix TT bootup freeze / unexpected (SCU) interrupt messagesEero Tamminen
Avoid freeze on Atari TT / MegaSTe boot with continuous messages of: unexpected interrupt from 112 Which was due to VBL interrupt being enabled in SCU sys mask, but there being no handler for that any more. (Bug and fix were first verified on real Atari TT HW by Christian, this patch later on in Hatari emulator.)
