--Apple-Mail=_EC9B015C-E14A-4AE9-A73C-F9BFA1724905 Content-Transfer-Encoding: quoted-printable Content-Type: text/plain; charset=utf-8 I have not followed all the TCPM discussion but how would tt_rexmt be active if you are in keep-alive? Keep alive can only go active if there is nothing to send and nothing outstanding.. so why would tt_rexmt be ever active? For persists I am not so sure. Normally you go into persists when you have data to send and the rwnd of the peer has closed. Again if that=E2=80=99s true i.e. you have data for the peer, then you would never be in KEEP.. though I could see where the peer ack=E2=80=99d the last byte and closed its window to zero=E2=80=A6 in = this case you *might* want both but I need to think about that case its a bit strange ;-) R > On Feb 16, 2021, at 8:09 AM, Scheffenegger, Richard = <Richard.Scheffenegger@netapp.com> wrote: >=20 > Hi, >=20 > =46rom the discussion @tcpm, around 793bis - shall we add conditionals = to reset the TT_KEEP timer, in case a tt_persist or tt_rexmt are active? >=20 > Richard Scheffenegger >=20 > _______________________________________________ > freebsd-transport@freebsd.org mailing list > = https://www.google.com/url?q=3Dhttps://lists.freebsd.org/mailman/listinfo/= freebsd-transport&source=3Dgmail-imap&ust=3D1614085792000000&usg=3DAOvVaw2= ciULW3x5JgabucL9hRXNI > To unsubscribe, send any mail to = "freebsd-transport-unsubscribe@freebsd.org" ------ Randall Stewart rrs@netflix.com --Apple-Mail=_EC9B015C-E14A-4AE9-A73C-F9BFA1724905 Content-Disposition: attachment; filename=smime.p7s Content-Type: application/pkcs7-signature; name=smime.p7s Content-Transfer-Encoding: base64 MIAGCSqGSIb3DQEHAqCAMIACAQExDzANBglghkgBZQMEAgEFADCABgkqhkiG9w0BBwEAAKCCAzYw ggMyMIICGqADAgECAgqxywKqrHPB2ybTMA0GCSqGSIb3DQEBCwUAMEcxGDAWBgNVBAMTD1JhbmRh bGwgU3Rld2FydDEeMBwGCSqGSIb3DQEJARYPcnJzQG5ldGZsaXguY29tMQswCQYDVQQGEwJVUzAe Fw0yMTAxMjQxMjIwMTRaFw0yNjAxMjQxMjIwMTRaMEcxGDAWBgNVBAMTD1JhbmRhbGwgU3Rld2Fy dDEeMBwGCSqGSIb3DQEJARYPcnJzQG5ldGZsaXguY29tMQswCQYDVQQGEwJVUzCCASIwDQYJKoZI hvcNAQEBBQADggEPADCCAQoCggEBAMUAht2nr/NFlK+tmmN9PdO3DBPfeYh9fLcbVihR+/dipO41 AsFy9y+2uDVaFhTEvp406P0o9PQQTuYXqrCr76eWQIj3V787e1WKjTup1mIyQeWHGf1gvb/7vmI2 zHg6QZEIC4W8xeO8SLKyHiwlFHZn8Rn1HxtB7Ge+NulygkgUgJYhXD5E29jVGXAc6Qn9Vr9AexPf KaOhHCaNB/Twcinayz6D8CO/Ym1LOs3+ceSOa4cB07fepmbqDSXDkOeA3U7KLaluHrRTlj6DO+JU nqKXX7jJ68KTYSZ0qH4fZsk8cxFkwYI/3HDJi+oF+FDkf7SRo1Q2w+e3M/5MReLIQ7sCAwEAAaMg MB4wDwYJKoZIhvcvAQEKBAIFADALBgNVHQ8EBAMCB4AwDQYJKoZIhvcNAQELBQADggEBAHJfum1j 1WIVFjOJT/hqMIN751aXkablmwesW94lNJKjslPULbbcP5nZGg2lGpHcZ+0I5F/1TTiEsT2H2rhA uAnSsUxTpxRA+aoe+xtJOa5vle3CprhFkHAvB7EIoLiNaPd0DNK6kKYsbvr5Z5Eq7TF3SIO77Qh9 /8VgUfOb0ARDgix59Q6MM0NmIabEwh0cDWQYlGgDDtN9DNk5PGM4pjs48suwEdLmFTMOmGTkCp7I Vq6iHDNinBiB6+BB4VYMAO1o9qS+0pnfdmPJybt0zVGrhm/c1Fmm3Jec7NEuiKeXmhPIwdwMkKyp AsX0sHuFCYwioBTHHZpvnir+H2rRakgxggHrMIIB5wIBATBVMEcxGDAWBgNVBAMTD1JhbmRhbGwg U3Rld2FydDEeMBwGCSqGSIb3DQEJARYPcnJzQG5ldGZsaXguY29tMQswCQYDVQQGEwJVUwIKscsC qqxzwdsm0zANBglghkgBZQMEAgEFAKBpMBgGCSqGSIb3DQEJAzELBgkqhkiG9w0BBwEwHAYJKoZI hvcNAQkFMQ8XDTIxMDIxNzE1MzYzMVowLwYJKoZIhvcNAQkEMSIEIDW3RcN76txR6cSwsi+lwU7K 2kWh6mhbh//zleldo9NtMA0GCSqGSIb3DQEBCwUABIIBAB7yaauuTzMhNP7zRyCn09AVnw3iUiY0 wPluxgnZQtbogTwZWhPDx9/ZFMV86VBfyvVCMhi75QvwPhpQef/J5zkCZnQggfrpU5FagvT6geTG I0Jz7qzTt+mRkw8h8cuVbppXq+RffOJ2M5V7n3el03WYTKweNxoQByMiKLF9JF+hfZIBjNOB/W08 IP+MPknDm+1U/KNDF9ujuw7ILEBmBjzrwUsF9k4DXkXaW+ukVAlRTmpSc8Ntam5OEI2Ar5gsG7FU af2KgVwMFSiYwWLmCWC+HrVCZDfYiDmVa8iH7clt1RVICGdfzmWZm/n0WA9uAeOTYEdb41KacBDR 9RovtAYAAAAAAAA= --Apple-Mail=_EC9B015C-E14A-4AE9-A73C-F9BFA1724905--
