  • aaa248f6c   [PATCH] rename net_random to random32 ... Browse Code »

    Make net_random() more widely available by calling it random32

    akpm: hopefully this will permit the removal of carta_random32. That needs
    confirmation from Stephane - this code looks somewhat more computationally
    expensive, and has a different (ie: callee-stateful) interface.

    [akpm@osdl.org: lots of build fixes, cleanups]

  • 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.

  • 90ddc4f04   [NET]: move struct proto_ops to const ... Browse Code »

    I noticed that some of 'struct proto_ops' used in the kernel may share
    a cache line used by locks or other heavily modified data. (default
    linker alignement is 32 bytes, and L1_CACHE_LINE is 64 or 128 at
    least)

    This patch makes sure a 'struct proto_ops' can be declared as const,
    so that all cpus can share all parts of it without false sharing.

    This is not mandatory : a driver can still use a read/write structure
    if it needs to (and eventually a __read_mostly)

    I made a global stubstitute to change all existing occurences to make
    them const.

    This should reduce the possibility of false sharing on SMP, and
    speedup some socket system calls.

  • 4dc3b16ba   [PATCH] DocBook: changes and extensions to the kernel documentation ... Browse Code »

    I have recompiled Linux kernel 2.6.11.5 documentation for me and our
    university students again. The documentation could be extended for more
    sources which are equipped by structured comments for recent 2.6 kernels. I
    have tried to proceed with that task. I have done that more times from 2.6.0
    time and it gets boring to do same changes again and again. Linux kernel
    compiles after changes for i386 and ARM targets. I have added references to
    some more files into kernel-api book, I have added some section names as well.
    So please, check that changes do not break something and that categories are
    not too much skewed.

    I have changed kernel-doc to accept "fastcall" and "asmlinkage" words reserved
    by kernel convention. Most of the other changes are modifications in the
    comments to make kernel-doc happy, accept some parameters description and do
    not bail out on errors. Changed to @pid in the description, moved some
    #ifdef before comments to correct function to comments bindings, etc.

    You can see result of the modified documentation build at
    http://cmp.felk.cvut.cz/~pisa/linux/lkdb-2.6.11.tar.gz

    Some more sources are ready to be included into kernel-doc generated
    documentation. Sources has been added into kernel-api for now. Some more
    section names added and probably some more chaos introduced as result of quick
    cleanup work.

    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!
