  • sys_shmdt() can manage shm segments which are covered by multiple vmas. (This
    can happen when a user uses mprotect() after shmat().)

    This works well if shm is aligned to PAGE_SIZE, but if not, the last
    segment cannot be detached. It is because a comparison in sys_shmdt()

    (vma->vm_end - addr) < size
    addr == return address of shmat()
    size == shmsize, argments to shmget()

    size should be aligned to PAGE_SIZE before being compared with vma->vm_end,
    which is aligned.

  • - Move capable() from sched.h to capability.h;

    - Use where capable() is used
    (in include/, block/, ipc/, kernel/, a few drivers/,
    mm/, security/, & sound/;
    many more drivers/ to go)

  • The attached patch makes the SYSV IPC shared memory facilities use the new
    ramfs facilities on a no-MMU kernel.

    The following changes are made:

    (1) There are now shmem_mmap() and shmem_get_unmapped_area() functions to
    allow the IPC SHM facilities to commune with the tiny-shmem and shmem
    code.

    (2) ramfs files now need resizing using do_truncate() rather than by modifying
    the inode size directly (see shmem_file_setup()). This causes ramfs to
    attempt to bind a block of pages of sufficient size to the inode.

    (3) CONFIG_SYSVIPC is no longer contingent on CONFIG_MMU.

  • Add SHM_NORESERVE functionality similar to MAP_NORESERVE for shared memory
    segments.

    This is mainly to avoid abuse of OVERCOMMIT_ALWAYS and this flag is ignored
    for OVERCOMMIT_NEVER.

  • Initial git repository build. I'm not bothering with the full history,
    even though we have it. We can create a separate "historical" git
    archive of that later if we want to, and in the meantime it's about
    3.2GB when imported into git - space that would just make the early
    git days unnecessarily complicated, when we don't have a lot of good
    infrastructure for it.

    Let it rip!
