  • b6ca8bd5a   xfrm: Move child route linkage into xfrm_dst. ... Browse Code »

    XFRM bundle child chains look like this:

    xdst1 --> xdst2 --> xdst3 --> path_dst

    All of xdstN are xfrm_dst objects and xdst->u.dst.xfrm is non-NULL.
    The final child pointer in the chain, here called 'path_dst', is some
    other kind of route such as an ipv4 or ipv6 one.

    The xfrm output path pops routes, one at a time, via the child
    pointer, until we hit one which has a dst->xfrm pointer which
    is NULL.

    We can easily preserve the above mechanisms with child sitting
    only in the xfrm_dst structure. All children in the chain
    before we break out of the xfrm_output() loop have dst->xfrm
    non-NULL and are therefore xfrm_dst objects.

    Since we break out of the loop when we find dst->xfrm NULL, we
    will not try to dereference 'dst' as if it were an xfrm_dst.

    The following semantic patch does part of the transformation:
    //
    @ rule1 @
    struct xt_match ops;
    identifier check;
    @@
    ops.checkentry = check;

    Restore function signatures from bool to int so that we can report
    memory allocation failures or similar using -ENOMEM rather than
    always having to pass -EINVAL back.

    This semantic patch may not be too precise (checking for functions
    that use xt_mtchk_param rather than functions referenced by
    xt_match.checkentry), but reviewed, it produced the intended result.

    //
    @@
    type bool;
    identifier check, par;
    @@
    -bool check
    +int check
    (struct xt_mtchk_param *par) { ... }

  • adf30907d   net: skb->dst accessors ... Browse Code »

    Define three accessors to get/set dst attached to a skb

    struct dst_entry *skb_dst(const struct sk_buff *skb)

    void skb_dst_set(struct sk_buff *skb, struct dst_entry *dst)

    void skb_dst_drop(struct sk_buff *skb)
    This one should replace occurrences of :
    dst_release(skb->dst)
    skb->dst = NULL;

    Delete skb->dst field
