Merge branch 'slab/for-6.19/freelist_aba_t_cleanups' into slab/for-nextMerge series "slab: cmpxchg cleanups enabled by -fms-extensions"From the cover letter [1]:After learning about -fms-extensions being enabled for 6.19, I realizedthere is some cleanup potential in slub code by extending the definitionand usage of freelist_aba_t, as it can now become an unnamed member ofstruct slab. This series performs the cleanup, with no functionalchanges intended. Additionally we turn freelist_aba_t to structfreelist_counters as it doesn't meet any criteria for being a typedef,per Documentation/process/coding-style.rstBased on the tag kbuild-ms-extensions-6.19 fromgit://git.kernel.org/pub/scm/linux/kernel/git/kbuild/linuxVLink: https://lore.kernel.org/all/20251107-slab-fms-cleanup-v1-0-650b1491ac9e@suse.cz/#t [1] List of files: /linux/arch/s390/Makefile

Merge tag 's390-6.19-1' of git://git.kernel.org/pub/scm/linux/kernel/git/s390/linuxPull s390 updates from Heiko Carstens: - Provide a new interface for dynamic configuration and deconfiguration of hotplug memory, allowing with and without memmap_on_memory support. This makes the way memory hotplug is handled on s390 much more similar to other architectures - Remove compat support. There shouldn't be any compat user space around anymore, therefore get rid of a lot of code which also doesn't need to be tested anymore - Add stackprotector support. GCC 16 will get new compiler options, which allow to generate code required for kernel stackprotector support - Merge pai_crypto and pai_ext PMU drivers into a new driver. This removes a lot of duplicated code. The new driver is also extendable and allows to support new PMUs - Add driver override support for AP queues - Rework and extend zcrypt and AP trace events to allow for tracing of crypto requests - Support block sizes larger than 65535 bytes for CCW tape devices - Since the rework of the virtual kernel address space the module area and the kernel image are within the same 4GB area. This eliminates the need of weak per cpu variables.

f5730d44e05efb43a5cb64e5eb04e24994bbb50f - s390: Add stackprotector support

Mon, 17 Nov 2025 15:09:53 +0100

s390: Add stackprotector supportStackprotector support was previously unavailable on s390 because bydefault compilers generate code which is not suitable for the kernel:the canary value is accessed via thread local storage, where the addressof thread local storage is within access registers 0 and 1.Using those registers also for the kernel would come with a significantperformance impact and more complicated kernel entry/exit code, sinceaccess registers contents would have to be exchanged on every kernel entryand exit.With the upcoming gcc 16 release new compiler options will become availablewhich allow to generate code suitable for the kernel. [1]Compiler option -mstack-protector-guard=global instructs gcc to generatestackprotector code that refers to a global stackprotector canary value viasymbol __stack_chk_guard. Access to this value is guaranteed to occur vialarl and lgrl instructions.Furthermore, compiler option -mstack-protector-guard-record generates asection containing all code addresses that reference the canary value.To allow for per task canary values the instructions which load the addressof __stack_chk_guard are patched so they access a lowcore field instead: aper task canary value is available within the task_struct of each task, andis written to the per-cpu lowcore location on each context switch.Also add sanity checks and debugging option to be consistent with otherkernel code patching mechanisms.Full debugging output can be enabled with the following kernel command lineoptions:debug_stackprotectorbootdebugignore_loglevelearlyprintkdyndbg="file stackprotector.c +p"Example debug output:stackprot: 0000021e402d4eda: c010005a9ae3 -> c01f00070240where ": -> ".[1] gcc commit 0cd1f03939d5 ("s390: Support global stack protector")Reviewed-by: Sven Schnelle Signed-off-by: Heiko Carstens List of files: /linux/arch/s390/Makefile
