[lwip-devel] [patch #9039] tcp: Avoid 3-second delay for a half-open connection

[Joel Cunningham]

Follow-up Comment #8, patch #9039 (project lwip):

Simon,

I assume you mean my list of checks for SYN-SENT?  I just summarized the steps
listed in RFC 793.  The only deviation I see in LwIP (with the fix applied
from this patch) is that in the case we receive ONLY the ACK flag (and it's
acceptable) we are still sending an RST.  RFC 793 says this should be silently
dropped.

I can't think of a case where this would happen, but I thought the deviation
from RFC 793 was worth mentioning
