    Transform some calls to kmalloc/memset to a single kzalloc (or kcalloc).

    Here is a short excerpt of the semantic patch performing
    this transformation:

  • 606f585e3   [PPP_MPPE]: Fix "osize too small" check. ... Browse Code »

    Prevent mppe_decompress() from generating "osize too small" errors when
    checking for output buffer size. When receiving a packet of mru size the
    output buffer for decrypted data is 1 byte too small since
    mppe_decompress() tries to account for possible PFC, however later in code
    it is assumed no PFC.

    Adjusting the check prevented these errors from occurring.

  • 5cbded585   [PATCH] getting rid of all casts of k[cmz]alloc() calls ... Browse Code »

    Run this:

    #!/bin/sh
    for f in $(grep -Erl "\([^\)]*\) *k[cmz]alloc" *) ; do
    echo "De-casting $f..."
    perl -pi -e "s/ ?= ?\([^\)]*\) *(k[cmz]alloc) *\(/ = \1\(/" $f
    done

    And then go through and reinstate those cases where code is casting pointers
    to non-pointers.

    And then drop a few hunks which conflicted with outstanding work.

  • b3f9b92a6   [PPP]: add PPP MPPE encryption module ... Browse Code »

    From: Matt Domsch

    The patch below implements the Microsoft Point-to-Point Encryption method
    as a PPP compressor/decompressor. This is necessary for Linux clients and
    servers to interoperate with Microsoft Point-to-Point Tunneling Protocol
    (PPTP) servers (either Microsoft PPTP servers or the poptop project) which
    use MPPE to encrypt data when creating a VPN.

    This patch differs from the kernel_ppp_mppe DKMS pacakge at
    pptpclient.sourceforge.net by utilizing the kernel crypto routines rather
    than providing its own SHA1 and arcfour implementations.

    Minor changes to ppp_generic.c try to prevent a link from disabling
    compression (in our case, the encryption) after it has started using
    compression (encryption).

    Feedback to please.
