  • ec8c0446b   [PATCH] Optimize D-cache alias handling on fork ... Browse Code »

    Virtually index, physically tagged cache architectures can get away
    without cache flushing when forking. This patch adds a new cache
    flushing function flush_cache_dup_mm(struct mm_struct *) which for the
    moment I've implemented to do the same thing on all architectures
    except on MIPS where it's a no-op.

  • b21a32371   [PATCH] remove the broken BLK_DEV_SWIM_IOP driver ... Browse Code »

    The BLK_DEV_SWIM_IOP driver has:
    - already been marked as BROKEN in 2.6.0 three years ago and
    - is still marked as BROKEN.

    Drivers that had been marked as BROKEN for such a long time seem to be
    unlikely to be revived in the forseeable future.

    But if anyone wants to ever revive this driver, the code is still
    present in the older kernel releases.

  • be90038a2   [PATCH] tty: preparatory structures for termios revamp ... Browse Code »

    In order to sort out our struct termios and add proper speed control we need
    to separate the kernel and user termios structures. Glibc is fine but the
    other libraries rely on the kernel exported struct termios and we need to
    extend this without breaking the ABI/API

    To do so we add a struct ktermios which is the kernel view of a termios
    structure and overlaps the struct termios with extra fields on the end for
    now. (That limitation will go away in later patches). Some platforms (eg
    alpha) planned ahead and thus use the same struct for both, others did not.

    This just adds the structures but does not use them, it seems a sensible
    splitting point for bisect if there are compile failures (not that I expect
    them)

    Pass struct dev pointer to dma_cache_sync()

    dma_cache_sync() is ill-designed in that it does not have a struct device
    pointer argument which makes proper support for systems that consist of a
    mix of coherent and non-coherent DMA devices hard. Change dma_cache_sync
    to take a struct device pointer as first argument and fix all its callers
    to pass it.

    so they are still there.

  • 2850bc273   [PATCH] m68k pt_regs fixes ... Browse Code »

    m68k_handle_int() split in two functions: __m68k_handle_int() takes
    pt_regs * and does set_irq_regs(); m68k_handle_int() doesn't get pt_regs
    *.

    Places where we used to call m68k_handle_int() recursively with the same
    pt_regs have simply lost the second argument, the rest is switched to
    __m68k_handle_int().

    The rest of patch is just dropping pt_regs * where needed.

  • 135ab6ec8   [PATCH] remove remaining errno and __KERNEL_SYSCALLS__ references ... Browse Code »

    The last in-kernel user of errno is gone, so we should remove the definition
    and everything referring to it. This also removes the now-unused lib/execve.c
    file that was introduced earlier.

    Also remove every trace of __KERNEL_SYSCALLS__ that still remained in the
    kernel.

  • 46a82b2d5   [PATCH] Standardize pxx_page macros ... Browse Code »

    One of the changes necessary for shared page tables is to standardize the
    pxx_page macros. pte_page and pmd_page have always returned the struct
    page associated with their entry, while pte_page_kernel and pmd_page_kernel
    have returned the kernel virtual address. pud_page and pgd_page, on the
    other hand, return the kernel virtual address.

    Shared page tables needs pud_page and pgd_page to return the actual page
    structures. There are very few actual users of these functions, so it is
    simple to standardize their usage.

    Since this is basic cleanup, I am submitting these changes as a standalone
    patch. Per Hugh Dickins' comments about it, I am also changing the
    pxx_page_kernel macros to pxx_page_vaddr to clarify their meaning.

  • 52393ccc0   [PATCH] remove set_wmb - arch removal ... Browse Code »

    set_wmb should not be used in the kernel because it just confuses the
    code more and has no benefit. Since it is not currently used in the
    kernel this patch removes it so that new code does not include it.

    All archs define set_wmb(var, value) to do { var = value; wmb(); }
    while(0) except ia64 and sparc which use a mb() instead. But this is
    still moot since it is not used anyway.

    Hasn't been tested on any archs but x86 and x86_64 (and only compiled
    tested)

  • 877ce7c1b   [AF_UNIX]: Datagram getpeersec ... Browse Code »

    This patch implements an API whereby an application can determine the
    label of its peer's Unix datagram sockets via the auxiliary data mechanism of
    recvmsg.

    Patch purpose:

    This patch enables a security-aware application to retrieve the
    security context of the peer of a Unix datagram socket. The application
    can then use this security context to determine the security context for
    processing on behalf of the peer who sent the packet.

    Patch design and implementation:

    The design and implementation is very similar to the UDP case for INET
    sockets. Basically we build upon the existing Unix domain socket API for
    retrieving user credentials. Linux offers the API for obtaining user
    credentials via ancillary messages (i.e., out of band/control messages
    that are bundled together with a normal message). To retrieve the security
    context, the application first indicates to the kernel such desire by
    setting the SO_PASSSEC option via getsockopt. Then the application
    retrieves the security context using the auxiliary data mechanism.

    An example server application for Unix datagram socket should look like this:

    toggle = 1;
    toggle_len = sizeof(toggle);

    setsockopt(sockfd, SOL_SOCKET, SO_PASSSEC, &toggle, &toggle_len);
    recvmsg(sockfd, &msg_hdr, 0);
    if (msg_hdr.msg_controllen > sizeof(struct cmsghdr)) {
    cmsg_hdr = CMSG_FIRSTHDR(&msg_hdr);
    if (cmsg_hdr->cmsg_len cmsg_level == SOL_SOCKET &&
    cmsg_hdr->cmsg_type == SCM_SECURITY) {
    memcpy(&scontext, CMSG_DATA(cmsg_hdr), sizeof(scontext));
    }
    }

    sock_setsockopt is enhanced with a new socket option SOCK_PASSSEC to allow
    a server socket to receive security context of the peer.

    Testing:

    We have tested the patch by setting up Unix datagram client and server
    applications. We verified that the server can retrieve the security context
    using the auxiliary data mechanism of recvmsg.
