The goal is for kern_table to only have sysctl elements. All this increases modularity by placing the ctl_tables closer to where they are used while reducing the chances of merge conflicts in kernel/sysctl.c. - Fixed sysctl unit test panic by relocating it to selftests* tag 'sysctl-6.16-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/sysctl/sysctl: sysctl: Close test ctl_headers with a for loop sysctl: call sysctl tests with a for loop sysctl: Add 0012 to test the u8 range check sysctl: move u8 register test to lib/test_sysctl.c sparc: mv sparc sysctls into their own file under arch/sparc/kernel stack_tracer: move sysctl registration to kernel/trace/trace_stack.c tracing: Move trace sysctls into trace.c signal: Move signal ctl tables into signal.c panic: Move panic ctl tables into panic.c List of files: /linux/kernel/sysctl-test.c

sysctl: move u8 register test to lib/test_sysctl.cIf the test added in commit b5ffbd139688 ("sysctl: move the extra1/2boundary check of u8 to sysctl_check_table_array") is run as a module, alingering reference to the module is left behind, and a 'sysctl -a'leads to a panic.To reproduce CONFIG_KUNIT=y CONFIG_SYSCTL_KUNIT_TEST=mThen run these commands: modprobe sysctl-test rmmod sysctl-test sysctl -aThe panic varies but generally looks something like this: BUG: unable to handle page fault for address: ffffa4571c0c7db4 #PF: supervisor read access in kernel mode #PF: error_code(0x0000) - not-present page PGD 100000067 P4D 100000067 PUD 100351067 PMD 114f5e067 PTE 0 Oops: Oops: 0000 [#1] SMP NOPTI ... ... ...

Wed, 26 Mar 2025 12:42:07 +0000

Merge branch 'for-6.15/amd_sfh' into for-linusFrom: Mario Limonciello Some platforms include a human presence detection (HPD) sensor. Whenenabled and a user is detected a wake event will be emitted from thesensor fusion hub that software can react to.Example use cases are "wake from suspend on approach" or to "lockwhen leaving".This is currently enabled by default on supported systems, but userscan't control it. This essentially means that wake on approach isenabled which is a really surprising behavior to users that don'texpect it.Instead of defaulting to enabled add a sysfs knob that users canuse to enable the feature if desirable and set it to disabled bydefault.

Merge tag 'constfy-sysctl-6.14-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/sysctl/sysctlPull sysctl table constification from Joel Granados: "All ctl_table declared outside of functions and that remain unmodified after initialization are const qualified. This prevents unintended modifications to proc_handler function pointers by placing them in the .rodata section.

1751f872cc97f992ed5c4c72c55588db1f0021e1 - treewide: const qualify ctl_tables where applicable

Tue, 28 Jan 2025 12:48:37 +0000

treewide: const qualify ctl_tables where applicableAdd the const qualifier to all the ctl_tables in the tree except forwatchdog_hardlockup_sysctl, memory_allocation_profiling_sysctls,loadpin_sysctl_table and the ones calling register_net_sysctl (./net,drivers/inifiniband dirs). These are special cases as they use aregistration function with a non-const qualified ctl_table argument ormodify the arrays before passing them on to the registration function.Constifying ctl_table structs will prevent the modification ofproc_handler function pointers as the arrays would reside in .rodata.This is made possible after commit 78eb4ea25cd5 ("sysctl: treewide:constify the ctl_table argument of proc_handlers") constified all theproc_handlers.Created this by running an spatch followed by a sed command:Spatch: virtual patch @ depends on !(file in "net") disable optional_qualifier @ identifier table_name != { watchdog_hardlockup_sysctl, iwcm_ctl_table, ucma_ctl_table, memory_allocation_profiling_sysctls, loadpin_sysctl_table }; @@ + const struct ctl_table table_name [] = { ... };sed: sed --in-place \ -e "s/struct ctl_table .table = &uts_kern/const struct ctl_table *table = \&uts_kern/" \ kernel/utsname_sysctl.cReviewed-by: Song Liu Acked-by: Steven Rostedt (Google) # for kernel/trace/Reviewed-by: Martin K.
