4f40d9635a Fix nic config with mismatched gateway family 
When a gateway exists on a family the node
does not exist for, handle the gateway better.

calls to allow eventlet to properly
background the process.

c0287e93ed Roll back rsync ownership 
Unfortunately, it will try to change parent directories on the way to
the files actually being written.

This will be used for owner=, group=, and permissions=
options.

a0ca3d3122 Extend snmp timeout 
Default is 1 second, bump to 2 seconds for some
extraordinarily slow switches.  This changes
overall to about 10 seconds as there are, by default,
5 retries.

e52a9ff70f Have syncfiles attempt to preserve more 
We cannot preserve symlinks (since we need them intact),
but we can use other rsync features to make synchronization work
better by default.

26c6f1407b Add syntax for noderange filtering 
/etc/passwd -> compute,-n11:/etc/passwd

compute,-n11 noderange.

172008f942 Attempt to cover centos stream 9 by el8 
At first glance, there should be similarities,
apart from python differences and need for
different clortho build due to library mismatch.

d666050ef7 Consolidate neigh wait time in slp 
Rather than incurring it on each iteration (causing a scan to take
15 seconds in test), defer to
handle them all later (reducing to 5 seconds to scan).

3c72f9f18f Refactor slp neigh warm-up 
Rather than pulling it out at active_scan level, intervene deeply.

This fixes the problem where an ip gets used as a key rather than mac.

can also apply to ssdp.

c569826ff1 Improve scan result with missing neigh entries 
If no neigh table is present for
a given address, send a packet to
induce kernel activity.

Then wait for a bit over 2 seconds to allow for
2 retries (at default settings)
and then proceed assuming all findable neighbor table
entries will be found.

398c8b3a71 Improve syncfiles permission denied reporting 
When a non-readable file was
encountered, confluent would
cryptically report rsync failure.

Check for the usual culprit, unreadable files if rsync fails.

Cause this error to manifest with clearer text.

c1113430a2 Pass only the name rather than full sockaddr on retire 
Followers of a server that is retiring to join the better leader
were being given incorrect format which would fail in the dns lookup.

99ba4e7765 Handle ip aliases in pxe 
Use netutil assessment of the
best server ip for pxe responses.

Using 'recvip' is too simplistic for broadcast
packets.  recvip just gets the first ipv4 address on the interface,
when an alias may be better.

netutil assesses all the possible aliases, thus has better logic and pxe.py
now uses it.

929392c746 Fix hangs on check_output 
Eventlet narrowly targets overriding
select in subprocess, to avoid rewriting adequate functions.

However, subprocess does an 'optimization' to skip
select if there's fewer than 3 pipes to juggle and no timeout specified.

Induce python to always use select
by specifying a very long timeout.

This causes confluent to be able to spawn multiple subprocesses and
not be hung waiting for input.

4ab5cac3eb Generate random serial number for certificate 
Hardcoding 0x123 serial number would cause strict clients to reject the
certificate.

While we are still not guaranteeing uniqueness, the chances of a
duplicate are impossibly small.

7c617a160b Close socket in relay_data 
Closing the socket outside of relay_data causes relay_data
to stay alive, causing eventlet to think a filehandle is open that is not.

A reasonable question would be why eventlet fails to error that read
when the filehandle is closed, but for now, move the close activity
to the relay_data handler.

This resolves "Second simultaneous read on fileno" conditions introduced
by the fix for leaking filehandles.
