  • 2f1eb65f3   xfrm: Flushing empty SPD generates false events ... Browse Code »

    To see the effect make sure you have an empty SPD.
    On window1 "ip xfrm mon" and on window2 issue "ip xfrm policy flush"
    You get prompt back in window2 and you see the flush event on window1.
    With this fix, you still get prompt on window1 but no event on window2.

    Thanks to Alexey Dobriyan for finding a bug in earlier version
    when using pfkey to do the flushing.

  • 069c474e8   xfrm: Revert false event eliding commits. ... Browse Code »

    As reported by Alexey Dobriyan:

    --------------------
    setkey now takes several seconds to run this simple script
    and it spits "recv: Resource temporarily unavailable" messages.

    #!/usr/sbin/setkey -f
    flush;
    spdflush;

    add A B ipcomp 44 -m tunnel -C deflate;
    add B A ipcomp 45 -m tunnel -C deflate;

    spdadd A B any -P in ipsec
    ipcomp/tunnel/192.168.1.2-192.168.1.3/use;
    spdadd B A any -P out ipsec
    ipcomp/tunnel/192.168.1.3-192.168.1.2/use;
    --------------------

    Obviously applications want the events even when the table
    is empty. So we cannot make this behavioral change.

  • 7d720c3e4   percpu: add __percpu sparse annotations to net ... Browse Code »
    13

    Add __percpu sparse annotations to net.

    These annotations are to make sparse consider percpu variables to be
    in a different address space and warn if accessed without going
    through percpu accessors. This patch doesn't affect normal builds.

    The macro and type tricks around snmp stats make things a bit
    interesting. DEFINE/DECLARE_SNMP_STAT() macros mark the target field
    as __percpu and SNMP_UPD_PO_STATS() macro is updated accordingly. All
    snmp_mib_*() users which used to cast the argument to (void **) are
    updated to cast it to (void __percpu **).

  • d7c7544c3   netns xfrm: deal with dst entries in netns ... Browse Code »

    GC is non-existent in netns, so after you hit GC threshold, no new
    dst entries will be created until someone triggers cleanup in init_net.

    Make xfrm4_dst_ops and xfrm6_dst_ops per-netns.
    This is not done in a generic way, because it woule waste
    (AF_MAX - 2) * sizeof(struct dst_ops) bytes per-netns.

    Reorder GC threshold initialization so it'd be done before registering
    XFRM policies.

  • 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

  • d5654efd3   xfrm: Fix kernel panic when flush and dump SPD entries ... Browse Code »

    After flush the SPD entries, dump the SPD entries will cause kernel painc.

    Used the following commands to reproduct:

    - echo 'spdflush;' | setkey -c
    - echo 'spdadd 3ffe:501:ffff:ff01::/64 3ffe:501:ffff:ff04::/64 any -P out ipsec \
    ah/tunnel/3ffe:501:ffff:ff00:200:ff:fe00:b0b0-3ffe:501:ffff:ff02:200:ff:fe00:a1a1/require;\
    spddump;' | setkey -c
    - echo 'spdflush; spddump;' | setkey -c
    - echo 'spdadd 3ffe:501:ffff:ff01::/64 3ffe:501:ffff:ff04::/64 any -P out ipsec \
    ah/tunnel/3ffe:501:ffff:ff00:200:ff:fe00:b0b0-3ffe:501:ffff:ff02:200:ff:fe00:a1a1/require;\
    spddump;' | setkey -c

    This is because when flush the SPD entries, the SPD entry is not remove
    from the list.

    This patch fix the problem by remove the SPD entry from the list.
