    Subject[PATCHv2 net-2.6 0/4 (was 0/3)]: TCP fixes
    Date
    Hi Dave,

    Ok, here's the v2 series which tries hard to avoid opening loopholes
    to if condition in tcp_mark_head_lost which again would make the
    added tcp_fragment code to not execute :-). The rest (patches 3-4
    are identical to previous series 2-3). ...I repost the whole series
    to make it easy for you if you were fast enough to deleted them from
    your inbox already, others please bear me :-).

    --- v1 intro follows ---

    Here are some TCP fixes that resulted from the last weeks reports
    & debug. The first one is quite likely to hit but it's considerably
    harder to get it print an overflow warning, while I've seen two
    reports about the second one (one of them is for 2.6.24.y), please
    ignore the earlier version of the tcp_simple_retransmit patch. The
    FRTO patch is once again result of code review rather than some
    report but seems necessary to avoid detection of some not that
    likely cases as spurious RTOs when there were some other losses
    in the same window with the probe. Nevertheless, it should be safe
    to return non-FRTO behavior.

    ...So far, they're just compile tested. I'll see if I find some time
    to boot them on the evening.

    There might still be one fackets_out miscounter awaiting detection
    & debug output (I hope Georgi catches it) because none of these
    seem an obvious reason for triggery of the !sacked_out && fackets_out
    trap.

    All of them are also valid for stables but please note that it won't
    be too easy, at least for the first & second patch because of recent
    changes (especially if stable != 2.6.24.y). I'll try to do the
    adapted versions later on for the stable.
