sysctl handler (ouch!)
Add a "const" qualifier to the source of the copyin() and copyout()
functions - the other const warning in kern_sysctl.c was silenced when
copyout was declared as having a const source.. (which it is)
Move a lot of variables home to their own code (In good time before xmas :-)
Introduce the string descrition of format.
Add a couple more functions to poke into these marvels, while I try to
decide what the correct interface should look like.
Next is adding vars on the fly, and sysctl looking at them too.
Removed a tine bit of defunct and #ifdefed notused code in swapgeneric.
Convert the remaining sysctl stuff to the new way of doing things.
the devconf stuff is the reason for the large number of files.
Cleaned up some compiler warnings while I were there.
much as I'd like to, but the malloc stunt I tried for an interim for
sure does worse.
Now we can read and write from any kind of address-space, not only
user and kernel, using callbacks.
This may be over-generalization for now, but it's actually simpler.
structs and prototypes for syscalls.
Ifdefed duplicated decentralized declarations of args structs. It's
convenient to have this visible but they are hard to maintain. Some
are already different from the central declarations. 4.4lite2 puts
them in comments in the function headers but I wanted to avoid the
large changes for that.
This is here now. We can now access (the new) sysctl variables from the
kernel too and using functions to handle access is more sane now.
I will now attack sysctl variables in the rest of the kernel and get them
all converted to newspeak.
The goal is to make them "user-friendly" :-)
In the end this will allow a SNMP style "getnext" function, sysctl editing
in the boot-editor and/or debugger, LKMs can define sysctl vars when
they get loaded, and remove them when unloaded and other interesting
uses for dynamic sysctl variables.
string as possible and return ENOMEM if the entire string cannot
be returned. This brings the routines in line with how the man
page says they work, and how the calling routines are expecting
them to work. This allows the dummy uname() routine in libc to
obtain the version string, since the kernel version string is
longer than that normally returned by the uname() routine.
This is 3/4 of the fix for PR# 462.

syscall to allow applications linked against their libc's uname() to
work. Netscape 1.1N being a prime example, which prints:
"uname() failed. cant tell what system we're running on".
This change is a little ugly, but that's mainly because of the "interesting"
semantics of the BSDI extension.
Since ogetkerninfo() is only enabled by COMPAT_43, Netscape will only
be affected on kernels with that option (eg: "GENERIC")

via sysctl(8). The initial value of maxprocperuid is maxproc-1,
that of maxfilesperproc is maxfiles (untill maxfile will disappear)
Now it is at least possible to prohibit one user opening maxfiles

short, it gets filled uop to its length. This matches the getdomainname
and gethostname manual pages.
(getbootfile also uses this function and I think it should have the same
behaviour)
This also fixes a bug with keyinit where the seed was not saved in
/etc/skeykeys. So S/Key should be fully functional again.
