  • df1e2fb54   [PATCH] shmdt: check address alignment ... Browse Code »

    SUSv3 says the shmdt() function shall fail with EINVAL if the value of
    shmaddr is not the data segment start address of a shared memory segment:
    our sys_shmdt needs to reject a shmaddr which is not page-aligned.

    Does it have the potential to break existing apps?

    Hugh says

    "sys_shmdt() just does the wrong (unexpected) thing with a misaligned
    address: it'll fail on what you might expect it to succeed on, and only
    succeed on what it should definitely fail on.

    "That is, I think it behaves as if shmaddr gets rounded up, when the only
    understandable behaviour would be if it rounded it down.

    "Which does mean you'd have to be devious to see anything but EINVAL from
    a misaligned shmaddr there, so it's not terribly important."

  • 8c8570fb8   [PATCH] Capture selinux subject/object context information. ... Browse Code »

    This patch extends existing audit records with subject/object context
    information. Audit records associated with filesystem inodes, ipc, and
    tasks now contain SELinux label information in the field "subj" if the
    item is performing the action, or in "obj" if the item is the receiver
    of an action.

    These labels are collected via hooks in SELinux and appended to the
    appropriate record in the audit code.

    This additional information is required for Common Criteria Labeled
    Security Protection Profile (LSPP).

  • 8e36709d8   [PATCH] shmdt cannot detach not-alined shm segment cleanly. ... Browse Code »

    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.

  • a70ea994a   [NETLINK]: Fix a severe bug ... Browse Code »

    netlink overrun was broken while improvement of netlink.
    Destination socket is used in the place where it was meant to be source socket,
    so that now overrun is never sent to user netlink sockets, when it should be,
    and it even can be set on kernel socket, which results in complete deadlock
    of rtnetlink.

    Suggested fix is to restore status quo passing source socket as additional
    argument to netlink_attachskb().

    A little explanation: overrun is set on a socket, when it failed
    to receive some message and sender of this messages does not or even
    have no way to handle this error. This happens in two cases:
    1. when kernel sends something. Kernel never retransmits and cannot
    wait for buffer space.
    2. when user sends a broadcast and the message was not delivered
    to some recipients.

  • 7c7dce920   [PATCH] Fix double decrement of mqueue_mnt->mnt_count in sys_mq_open ... Browse Code »

    Fixed the refcounting on failure exits in sys_mq_open() and
    cleaned the logics up. Rules are actually pretty simple - dentry_open()
    expects vfsmount and dentry to be pinned down and it either transfers
    them into created struct file or drops them. Old code had been very
    confused in that area - if dentry_open() had failed either in do_open()
    or do_create(), we ended up dentry and mqueue_mnt dropped twice, once
    by dentry_open() cleanup and then by sys_mq_open().

    Fix consists of making the rules for do_create() and do_open()
    same as for dentry_open() and updating the sys_mq_open() accordingly;
    that actually leads to more straightforward code and less work on
    normal path.

  • b0e15190e   [PATCH] NOMMU: Make SYSV IPC SHM use ramfs facilities on NOMMU ... Browse Code »

    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.

    The following two patches convert /proc/sysvipc/* to use seq_file.

    This gives us the following:

    - Self-consistent IPC records in proc.
    - O(n) reading of the files themselves.

    This patch:

    Add a generic method for ipc types to be displayed using seq_file. This
    patch abstracts out seq_file iterating over struct ipc_ids into ipc/util.c

  • 202e5979a   [PATCH] compat: be more consistent about [ug]id_t ... Browse Code »

    When I first wrote the compat layer patches, I was somewhat cavalier about
    the definition of compat_uid_t and compat_gid_t (or maybe I just
    misunderstood :-)). This patch makes the compat types much more consistent
    with the types we are being compatible with and hopefully will fix a few
    bugs along the way.

    compat type type in compat arch
    __compat_[ug]id_t __kernel_[ug]id_t
    __compat_[ug]id32_t __kernel_[ug]id32_t
    compat_[ug]id_t [ug]id_t

    The difference is that compat_uid_t is always 32 bits (for the archs we
    care about) but __compat_uid_t may be 16 bits on some.

    semundo->lock can leak if semundo->refcount goes from 2 to 1 while
    another thread has it locked. This causes major problems for PREEMPT
    kernels.

    The simplest fix for now is to undo the single-thread optimization.

    This bug was found via relentless testing by Dominik Karall.

    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!
