git://git.kernel.org/pub/scm/linux/kernel/git/pcmoore/lsm Pull LSM updates from Paul Moore: - Add new credential functions, get_cred_many() and put_cred_many() to save some atomic_t operations for a few operations. While not strictly LSM related, this patchset had been rotting on the mailing lists for some time and since the LSMs do care a lot about credentials I thought it reasonable to give this patch a home. - Five patches to constify different LSM hook parameters. - Fix a spelling mistake. * tag 'lsm-pr-20231030' of git://git.kernel.org/pub/scm/linux/kernel/git/pcmoore/lsm: lsm: fix a spelling mistake cred: add get_cred_many and put_cred_many lsm: constify 'sb' parameter in security_sb_kern_mount() lsm: constify 'bprm' parameter in security_bprm_committed_creds() lsm: constify 'bprm' parameter in security_bprm_committing_creds() lsm: constify 'file' parameter in security_bprm_creds_from_file() lsm: constify 'sb' parameter in security_quotactl()

2023-10-30Merge tag 'execve-v6.7-rc1' of ↵Linus Torvalds
git://git.kernel.org/pub/scm/linux/kernel/git/kees/linux Pull execve updates from Kees Cook: - Support non-BSS ELF segments with zero filesz Eric Biederman and I refactored ELF segment loading to handle the case where a segment has a smaller filesz than memsz. Traditionally linkers only did this for .bss and it was always the last segment. As a result, the kernel only handled this case when it was the last segment. We've had two recent cases where linkers were trying to use these kinds of segments for other reasons, and the were in the middle of the segment list. There was no good reason for the kernel not to support this, and the refactor actually ends up making things more readable too. - Enable namespaced binfmt_misc Christian Brauner has made it possible to use binfmt_misc with mount namespaces. This means some traditionally root-only interfaces (for adding/removing formats) are now more exposed (but believed to be safe). - Remove struct tag 'dynamic' from ELF UAPI Alejandro Colomar noticed that the ELF UAPI has been polluting the struct namespace with an unused and overly generic tag named "dynamic" for no discernible reason for many many years. After double-checking various distro source repositories, it has been removed. - Clean up binfmt_elf_fdpic debug output (Greg Ungerer) * tag 'execve-v6.7-rc1' of git://git.kernel.org/pub/scm/linux/kernel/git/kees/linux: binfmt_misc: enable sandboxed mounts binfmt_misc: cleanup on filesystem umount binfmt_elf_fdpic: clean up debug warnings mm: Remove unused vm_brk() binfmt_elf: Only report padzero() errors when PROT_WRITE binfmt_elf: Use elf_load() for library binfmt_elf: Use elf_load() for interpreter binfmt_elf: elf_bss no longer used by load_elf_binary() binfmt_elf: Support segments with 0 filesz and misaligned starts elf, uapi: Remove struct tag 'dynamic'
