Use v3 protocol by default for NFS mounts. If v3 is not supported, v2 is

in the Lite2 merge to not export some nfs constants. It started causing

Removed `#define NFS'. This was an old, bad interface for telling

it's done for pci. This is so that systat and vmstat can get at the

kernel. This doesn't affect the normal kernel, but makes life easier for
the smp people who don't have to track two versions of config.
vnconfig doesn't seem to be in Lite2, although dev/vn is. The Lite2
merge in userland has converted all mount calls except this one and
one for devfs in init, so we can drop support for old mount args soon.
Vnconfig probably shouldn't support mounting - it only supports ufs.
non-standard and not used. "port auto" is equal to "port?" or missing "port"

I suspect it was because the child exec code's parent was doing the
initial lookups, then forking, then doing other things (possibly trashing
the static data in the getpw*() buffer), then attempting to dereference
*pwd and *lc. Also, no error checking appeared to be done - I've allowed
it to fall back to the old "become user" code on critical failure rather than
risk running a user's cron jobs as root.
Accept SIGHUP as a "re-open logfile" signal. As ppp
doesn't set it's serial line to it's controlling terminal,
we can use HUP :)
This is a candidate for 2.2. The log.[ch] changes won't
conflict, but the main.c changes will. We just want to change the
kill(...,SIGHUP) to a SIGTERM and change the signal(SIGHUP,Hangup)
to a pending_signal(SIGHUP,LogReOpen).
These changes should fix the signal "problems" in ppp.
The signal changes should really be put into 2.2 too !
The following patches should do it. There were some other
changes made by Andrey recently that havn't been brought
into 2.2, it may be worth doing them now.

dangerous! Signal handlers themself must be fixed to not call malloc,
but no pended handlers, it will be correct fix. In finite case each signal
handler can set some variable which will be analized later, but calling
handler functions manually is too dangerous (f.e. signals not blocked while
the handler or handlers switch executed in this case). Of course this
code can be fixed instead of removing, but it not worth fixing in any case.
Should go into 2.2
In addition sig.c code shows following dangerous fragments (there can be more,
but I stop after two):
This fragment
if (fn == SIG_DFL || fn == SIG_IGN) {
handler[sig-1] = (sig_type)0;
<------------- here
signal(sig,fn);
} else {
cause NULL pointer reference when signal comes
"here", but more worse fragment is below:
void handle_signals() {
int sig;
if (caused)
for (sig=0; sig<__MAXSIG; sig++, caused>>=1)
if (caused&1)
(*handler[sig])(sig+1);
}
caused is bitmask which set corresponding bit on each signal coming.
And now imagine, what happens when some signal comes (bit sets) while loop
is executed (see caused>>=1 !!!)
In this light carrier drop situation was (as gdb shows)
1. SIGSEGV in handle_signals because some junk called as *handler reference.
2. Since SIGSEGV was pended too (== never happens),
it can cause various range of disasters.

All signal() calls have been changed to pending_signal() calls.
pending_signal() is defined in the new sig.c file. It remembers
the handler and traps the signal with a function that will remember
the signal.
main.c now calls handle_signals() to actually call the required
handlers (if the above handler was called).
If this doesn't close PR2662 (was PR2347), I'll cry.
Joerg, I think this should go into 2.2, but I havn't done anything
about it because I'm bound to botch it with the new sig.[ch] files.

2. Back out my change to ask about UTC/Localtime here. This *really* needs

Now that this is becoming (dare I even say it?) more useful for

at the time, but on further reflection..." bucket with these changes.
1. Checking the media before frobbing the disks was a fine idea, and
I wish it could have worked, but that leads to a rather difficult
situation when you need to mount the media someplace and you're about
to:
a) Chroot away from your present root.
b) Newfs the root to be.
You're basically screwed since there's no place to stick the mount
point where it will be found following the newfs/chroot (and eliminating
the chroot in favor of just using the "root bias" feature would work
great for the distributions but not the pkg_add calls done by the
package installer).
2. Automatic timeout handling. I don't know why, but alarm() frequently
returns no residual even when the alarm didn't go off, which defies
the man page but hey, since when was that so unusual? Take out timeouts
but retain the code which temporarily replaces the SIGINT handler in
favor of a more media-specific handler. This way, at least, if it's hanging
you can at least whap it. I think the timeout code would have been losing
over *really slow* links anyway, so it's probably best that it go.
This should fix NFS, tape & CDROM installs again (serves me right for getting
complacent and using just the FTP installs in my testing).

section was a good thing, since it made it possible to detect media problems
*before* the installation started, but it also caused various things to
be mounted BEFORE the chroot() call, which definitely messes things up.
Fix this by detecting the pre-chroot() case and mounting into a subdir.
This will probably need to go away again someday when distributions get
folded into packages and there are no more dist files to check, but knowing
how long we've been waiting on THAT, this will be a welcome tool for the
interim.

We could also make this stuff only come out when getpid() != 1
and thus avoid the install case (where it really is just too verbose,
and people have complained), but this seems less messy and no one
complained when tzsetup didn't print the final "things went fine!"
messages (which sort of contravene the UNIX spirit of only yelling
when you need to anyway).
