Removals for net/, io_uring/, mm/, ipc/ and security/ are set to go into mainline through their respective subsystems making the next release the most likely place where the final series that removes the check for proc_name == NULL will land. This adds to removals already in arch/, drivers/ and fs/. - Adjust ctl_table definitions and references to allow constification - Remove unused ctl_table function arguments - Move non-const elements from ctl_table to ctl_table_header - Make ctl_table pointers const in ctl_table_root structure Making the static ctl_table structs const will increase safety by keeping the pointers to proc_handler functions in .rodata. Though no ctl_tables where made const in this PR, the ground work for making that possible has started with these changes sent by Thomas Weißschuh. * tag 'sysctl-6.10-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/sysctl/sysctl: sysctl: drop now unnecessary out-of-bounds check sysctl: move sysctl type to ctl_table_header sysctl: drop sysctl_is_perm_empty_ctl_table sysctl: treewide: constify argument ctl_table_root::permissions(table) sysctl: treewide: drop unused argument ctl_table_root::set_ownership(table) bpf: Remove the now superfluous sentinel elements from ctl_table array delayacct: Remove the now superfluous sentinel elements from ctl_table array kprobes: Remove the now superfluous sentinel elements from ctl_table array printk: Remove the now superfluous sentinel elements from ctl_table array scheduler: Remove the now superfluous sentinel elements from ctl_table array seccomp: Remove the now superfluous sentinel elements from ctl_table array timekeeping: Remove the now superfluous sentinel elements from ctl_table array ftrace: Remove the now superfluous sentinel elements from ctl_table array umh: Remove the now superfluous sentinel elements from ctl_table array kernel misc: Remove the now superfluous sentinel elements from ctl_table array 2024-04-25ipc: remove the now superfluous sentinel element from ctl_table arrayJoel Granados This commit comes at the tail end of a greater effort to remove the empty elements at the end of the ctl_table arrays (sentinels) which will reduce the overall build time size of the kernel and run time memory bloat by ~64 bytes per sentinel (further information Link : https://lore.kernel.org/all/ZO5Yx5JFogGi%2FcBo@bombadil.infradead.org/) Remove the sentinels from ipc_sysctls and mq_sysctls Link: https://lkml.kernel.org/r/20240328-jag-sysctl_remset_misc-v1-5-47c1463b3af2@samsung.com Signed-off-by: Joel Granados <j.granados@samsung.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> 2024-04-24sysctl: treewide: constify argument ctl_table_root::permissions(table)Thomas Weißschuh The permissions callback should not modify the ctl_table. Enforce this expectation via the typesystem. This is a step to put "struct ctl_table" into .rodata throughout the kernel. The patch was created with the following coccinelle script: @@ identifier func, head, ctl; @@ int func( struct ctl_table_header *head, - struct ctl_table *ctl) + const struct ctl_table *ctl) { ... } (insert_entry() from fs/proc/proc_sysctl.c is a false-positive) No additional occurrences of '.permissions =' were found after a tree-wide search for places missed by the conccinelle script.

One of these is the ctl_table_arg member of struct ctl_table_header. Constify this reference as a prerequisite for the full constification of struct ctl_table instances. No functional change.

Miller <davem@davemloft.net> 2024-02-22sysctl: allow to change limits for posix messages queuesAlexey Gladkov All parameters of posix messages queues (queues_max/msg_max/msgsize_max) end up being limited by RLIMIT_MSGQUEUE. The code in mqueue_get_inode is where that limiting happens. The RLIMIT_MSGQUEUE is bound to the user namespace and is counted hierarchically. We can allow root in the user namespace to modify the posix messages queues parameters.
