The clearing does\nnot protect FRTO because FRTO operates before fastretrans_alert.\nMoving the clearing of prior_ssthresh earlier seems to be a\nsuboptimal solution to the FRTO case because then FLAG_ECE will\ncause a second ssthresh reduction in try_to_open (the first\noccurred when FRTO was entered). So instead, FRTO falls back\nimmediately to the rate halving response, which switches TCP to\nCA_CWR state preventing the latter reduction of ssthresh.\n\nIf the first ECE arrived before the ACK after which FRTO is able\nto decide RTO as spurious, prior_ssthresh is already cleared.\nThus no undoing for ssthresh occurs. Besides, FLAG_ECE should be\nset also in the following ACKs resulting in rate halving response\nthat sees TCP is already in CA_CWR, which again prevents an extra\nssthresh reduction on that round-trip.\n\nIf the first ECE arrived before RTO, ssthresh has already been\nadapted and prior_ssthresh remains cleared on entry because TCP\nis in CA_CWR (the same applies also to a case where FRTO is\nentered more than once and ECE comes in the middle).\n\nHigh_seq must not be touched after tcp_enter_cwr because CWR\nround-trip calculation depends on it.\n\nI believe that after this patch, FRTO should be ECN-safe and\neven able to take advantage of synergy benefits.\n\nSigned-off-by: Ilpo Järvinen \u003cilpo.jarvinen@helsinki.fi\u003e\nSigned-off-by: David S.
