It's probably too late for this case, but if so, then something to keep in mind for a future case: IPsec latching (see ipsec_latch_t, in $SRC/uts/common/inet/ip.h). This could either be subsumed into ipinfo_t or, better, added as one more probe argument, both on receive and on send probes.
IPsec latching is a mechanism by which Solaris ensures that a connection uses the same IPsec protection parameters throughout its lifetime. IPsec latches are as ancilliary data sent up and down the stack along with the packet. Having IPsec latch info in these probes would allow one to observe the effect of using the IP_SEC_OPT socket option, as well as the effect of changing IPsec configuration. This will be useful mainly for observability. You could argue that IPsec support should come later, and I won't mind :) Sorry I missed this earlier. And thanks for adding the SACK and PMTU information. Nico -- _______________________________________________ opensolaris-arc mailing list opensolaris-arc@opensolaris.org
