As to the old libpkg, it only existed for little over a year and only in HEAD and was even removed from there over a year ago, and the commit message clearly states that it should not be used. OTOH, for those using it, the only alternative for them is probably pkgng which is only now turning stable.

Also, I don't like idea of removing IP address from interface when cable is unplugged. It was very disturbing behavior of Windows machines for years. I've unplug cable to change switch port for only a second and all connections are broken, even if one second later dhcpclient receive SAME lease! I don't like this.

Yes. Mosh helps. You can mosh to a different host, then do what you need to do to get to the cisco. Does mosh solve the problem in all cases, no. It just helps.

What Doug mentioned (and I don't think was really considered, but is valid) would break people that use pkg_* outside of ports. I know of at least two instances where this would be the case (one case that uses pkg_* directly, and another case that uses libpkg from pkg_* 0-o...). I know it's delaying the inevitable (pkg_* is going to go away), but we shouldn't count our chickens before they've hatched as far as how pkgng needs to be used and how things might change. The optional in 8/9/10, mandatory in 11 proposal seems very sane and it allows people to get things worked out properly without too many headaches.

For example, this script can replace devd as a daemon that restarts
dhclient when any link comes back up...
#!/bin/sh
daemon_loop () {
while true; do
read line
if [ -z "${line##!system=IFNET subsystem=* type=LINK_UP}" ] ; then
eval ${line##!}
/sbin/dhclient $subsystem
fi
done
}
cat /dev/devctl | daemon_loop
Of course the right thing to do is invoke the proper rc scripts rather
than dhclient directly... this is just to illustrate how easy it is to
replace devd if your needs are specialized.

Ok, this is what I came up with, somewhat loosely based on OpenBSD's dhclient.
I tested that it survives the following:
- Unplugging/replugging does not kill an existing ssh session
- Using ifconfig down/up does not kill an existing ssh session
- Plugging into a different network does cause dhclient to negotiate
a new lease on the new network
I've removed the bits to clear the old configuration if dhclient exits due to
'ifconfig down', and dhclient no longer exits on link down, but instead tracks
the link state and enters the 'reboot' state when the link goes up.

Those address different parts of the problem. Making pkg mandatory in 10 is different from where the old pkg_* tools end up. The command line tools are just the tip of the iceberg, there are a lot of interactions behind the scenes. > Personally, I think we should handle this the same way that other > replacement tools have been done, which is close to what Baptiste has > proposed.

The traditional model has been to deprecate in one release, remove in the next. And in this case, it doesn't matter how awesome the new tools are, they are a MAJOR paradigm shift for how users interact with ports, and we are going to have a lot of users who take years to transition their installed base. No matter how much we may want to move fast on this, it just isn't going to be possible. > If the new tools are good, but don't cover the older users, > we develop along size.

If you are fine with removing them if there's robust support, how can you also be suggesting that it is impossible and shouldn't be talked about? Personally, I think we should handle this the same way that other replacement tools have been done, which is close to what Baptiste has proposed. If the new tools are totally awesome, we have replaced old tools. If the new tools are good, but don't cover the older users, we develop along size. If they are lame, but somehow get committed anyway, we take 18 years to replace them with bsdinstall.

C++ isn't the problem. Devd's size wouldn't be any smaller if I'd written it in pure C. People have sent me patches that move it to pure C over time. Yet, when written in C, the binaries are the same size (well, within 10k), and the run-time speed and memory consumption are comparable. Devd was written with the small, embedded system in mind, and was always considered to be on the path to being mandatory (you are free to write your own devd-like program, if you like btw). Haven't looked at the dhclient issues surrounding this tread, but C++ size and bloat of devd is an argument not supported by the objective facts.

Until pkg becomes mandatory (which can't happen for several years) the pkg_* tools can't be removed altogether. What _would_ be useful is what should have been done many years ago when it was first suggested: Move the pkg_* tools to ports. It's too late for 9.1 already, but if you made that change today in HEAD, and after 9.1 (but before 8.4) you MFC it to stable/[89], then you could theoretically make pkg mandatory after 9.1 EOLs. To make my point more clear, the ports tree has to support the last release to ship with pkg_* tools in the base throughout its lifetime. To do anything else would be be a massive POLA violation.

I don't know what "teardown the configured lease" in that comment means, but it doesn't mean that the interface loses its current configuration, or that any existing connections are perturbed. If the cable is plugged back into the same network, the interface will get the same address it last had and existing connections continue to work, unless the dhcp server recycled that lease to another client while the cable was unplugged (highly unlikely unless the server/network is starved for addresses, since the dhcpd design is to avoid recycling recently-used addresses). The important point is that if you unplug the cable then plug it into a different network, now the right thing will happen -- you will acquire an address on the new network.

I haven't read commit mails in a very long time, but is there code in place that will issue a warning upon geli attach if version 7 is detected? While -CURRENT is not supported, there might be a lot of disks initialized with version 7 and they'll eventually be upgraded to 10.0-RELEASE (the OS, not necessarily the geli volumes).

And if I'm right about understanding what this change does, it is POLA violation for sure. Both consequences: unable to use dhcclient without devd (user will need to restart it by hands after each cable unplugging event) and removing IP address from interface on cable unplugging or other interface down event but before lease is expired. If I'm right in understanding this commit, I vote to back it out and find better solution, may be, two new options: one to remove IP and one to exit on interface down. And default behavior should be OLD ONE about IP address in any case and OLD ONE about exit in case when dhclient isn't started by devd, but by rc scripts directly. -- // Black Lion AKA Lev Serebryakov ___ freebsd-current@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-current To unsubscribe, send any mail to "freebsd-current-unsubscr...@freebsd.org"

in rc.conf - ifconfig_fxp0="SYNCDHCP"
in /etc/dhclient.conf
interface "fxp0" {
supersede domain-name "home";
supersede domain-name-servers 127.0.0.1;
}
Also /etc/start_if.fxp0
With content -
ifconfig fxp0 ether xx:xx:xx:xx:xx:xx
ifconfig fxp0 -tso
ifconfig fxp0 polling
And yes, no problem with static ip on fxp0 and no up/down sequence

I would like to use this opportunity to remind about another abuse in drivers: MAXBSIZE. This constant should be private to buffer cache / FS drivers layer, but some drivers abuse it for things related to physical I/O (mostly [only?] as bus_dma_tag_create parameter). -- Andriy Gapon ___ freebsd-current@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-current To unsubscribe, send any mail to "freebsd-current-unsubscr...@freebsd.org"
