  • af7c693f1   Cap shmmax at INT_MAX in compat shminfo ... Browse Code »

    The value of shmmax may be larger than will fit in the struct used by
    the 32bit compat version of sys_shmctl. This change mirrors what the
    normal sys_shmctl does when called with the old IPC_INFO command.

  • 651971cb7   [PATCH] Fix the size limit of compat space msgsize ... Browse Code »

    Currently we allocate 64k space on the user stack and use it the msgbuf for
    sys_{msgrcv,msgsnd} for compat and the results are later copied in user [
    by copy_in_user]. This patch introduces helper routines for
    sys_{msgrcv,msgsnd} as below:

    do_msgsnd() : Accepts the mtype and user space ptr to the buffer along with
    the msqid and msgflg.

    do_msgrcv() : Accepts a kernel space ptr to mtype and a userspace ptr to
    the buffer. The mtype has to be copied back the user space msgbuf by the
    caller.

    These changes avoid the need to allocate the msgsize on the userspace (
    thus removing the size limt ) and the overhead of an extra copy_in_user().

    Semaphore to mutex conversion.

    The conversion was generated via scripts, and the result was validated
    automatically via a script as well.

  • 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.

  • 214a627cb   [PATCH] put_compat_shminfo() warning fix ... Browse Code »

    GCC 4 complains because the function put_compat_shminfo() can't get to its
    return statement if there is no error... If the function does not return
    -EFAULT, it doesn't return anything at all. Looks like a typo.

    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!
