netstat: reduce use of historical Internet classes

2021-12-10T16:27:02+00:00

When attempting to characterize bound addresses, netstat was checking
for host 0 on a (historical) net using inet_lnaof().  Such addresses
are not normally bound, as they would not work, with the exception
of the unspecified address, INADDR_ANY.  Check for that explicitly.
Similarly, don't check bound addresses for a match to a network name.

Extend netstat to display TCP stack and detailed congestion state

2020-10-09T10:07:41+00:00

Adding the "-c" option used to show detailed per-connection
congestion control state for TCP sessions.

This is one summary patch, which adds the relevant variables into
xtcpcb. As previous "spare" space is used, these changes are ABI
compatible.

netstat: igmp stats, error on unexpected information, not only warn

2019-11-12T13:57:17+00:00

The igmp stats tend to print two lines of warning for an unexpected
version and length.  Despite an invalid version and struct size it
continues to try to do something with the data.  Do not try to parse
the remainder of the struct and error on warning.

Note the underlying issue of the data not being available properly
is still there and needs to be fixed seperately.

Restore description of packets dropped due to full reassembly queue.

2019-10-03T18:24:41+00:00

r265408 renamed tcps_rcvmemdrop to tcps_rcvreassfull and gave it a more
specific description.  r279122 (libxo-ification) reverted that change.
This commit brings it back, but with a small tweak to the description.
