`grep ^d_ conf.c >conf.h'. This accounts for part of its ugliness. The
prototypes should be moved back to the driver sources when the functions
are staticalized.

have to decide whether to send a CC or CCnew option in our SYN segment
depending on the contents of our TAO cache. This decision has to be
made once when the connection starts. The earlier code delayed this
decision until the segment was assembled in tcp_output() and
retransmitted SYN segments could have different CC options.

This means that a script containing:
echo 1

echo 2
will now produce output, like it does on SYSV machines and other 'proper'
/bin/sh implementations..
This is done by a slight restructure of the input processor allowing it to
read chunks from the file at a time, but process the data by line from the
chunk.

Bleah.. symorder.c is *horrible*. :-(
1. Fix the bogon I introduced that made some root filesystems fail to be
made with `unable to make filesystem on sd1s1a' or some such error
message.
2. Latest installment in the never-ending chapter on making FTP do the right
thing on a cruel internet.
3. Make `express install' a truly express install and split off what it used
to do into a `novice install' that's even more geared to the novice
by asking questions in order, rather than forcing them through the menu
interface.
4. Make anonymous FTP setup truly DTRT.
5. Build lndir directly into sysinstall and make the novice install offer
to set up the ports tree. Also make the ports setup truly explanatory
about what it's doing, and always link the ports destination to /usr/ports
if necessary so that bsd.port.mk doesn't need to be tweaked.
This causes:
1: inetd to clear it's getlogin() name at startup (in case the sysadmin
logged in and su'ed to root and restarted inetd)
2: inetd to start each spawned process in it's own session.
3: inetd to call setlogin() on non-root processes (eg: uucp for uucico)
4: log failures more extensively
This means that root spawned processes from inetd remain responsible for
setting their login name if they change their uid. (eg: rshd, login, etc).
If they do not do so, it is safer for them to have no "login name" than a
wrong one (like "root") because the getlogin() system call is documented
as "secure" on 4.4BSD. inetd when started from /etc/rc would have no login
name anyway, so this isn't really a change - it's making it consistant with
the bootup state...
The setsid() change *may* cause something to break that is doing a setsid()
itself and checking the result - it will fail now because it's already been
done. The consensis seems to be that this is unlikely. David G. thinks
this is acceptable as it is cleaner from an architectural point of view.
vector. Now it is called the "symbol caching" vector. This was made
possible and unconfusing by other changes that allowed me to localize
everything having to do with the caching vector in the function
reloc_map().
Switched to alloca() for allocating the caching vector, and eliminated
the special mmap-based allocation routines. Although this was motivated
by performance reasons, it led to significant simplification of the
code, and made it possible to confine the symbol caching code to the
single function reloc_map().
Got rid of the unnecessary and inefficient division loop at the
beginning of rtld().
Reduced the number of calls to getenv("LD_LIBRARY_PATH") to just 1, on
suggestion from <davidg@root.com>.
Added breaks out of the relocation loops when the relocation address is
found to be 0. A relocation address of 0 is caused by an unused
relocation entry. Unused relocation entries are caused by linking a
shared object with the "-Bsymbolic" switch. The runtime linker itself
is linked that way, and the last 40% of its relocation entries are
unused. Thus, breaking out of the loop on the first such entry is a
performance win when ld.so relocates itself. As a side benefit, it
permits removing a test from md_relocate_simple() in
../i386/md-static-funcs.c.
Unused relocation entries in other shared objects (linked with
"-Bsymbolic") caused even bigger problems in previous versions of the
runtime linker. The runtime linker interpreted the unused entries as if
they were valid. That caused it to perform repeated relocations of the
first byte of the shared object. In order to do that, it had to remap
the text segment writable. Breaking out of the loop on the first unused
relocation entry solves that.

This change should pretty well be in it's final form now.

There should probably be a standard way of getting the same information
going the other way.
