Mostly merge changes from HEAD upto 20200411

remove sup

convert most sprintf() to snprintf().

Sync with HEAD

- add or adjust /* FALLTHROUGH */ where appropriate
- add __unreachable() after functions that can return but won't in
  this case, and thus can't be marked __dead easily

Sync with HEAD

Drop main() prototype.

sync with head.

for a reference, the tree before this commit was tagged
as yamt-pagecache-tag8.

this commit was splitted into small chunks to avoid
a limitation of cvs.  ("Protocol error: too many arguments")

resync from head

return busy for checkchild instead of killing the connection

fix compilation issues.

- don't allow multiple active connections from the same host
- prefix all messages with the local hostname
- more error checking

NULL does not need a cast

don't decrement if children are 0

- safer way to count kids
- if we are really bombarded with connections, don't bother to fork() and
  converse.

improve error handling and logging.

change to strchr and strrchr

constification from Paul Ripke to make it compile on OS/X

sync with HEAD

include libc.h and c.h after all the headers, so that __unused is not defined
until the headers have been included.

patch from pkgsrc

sync with HEAD

portability fixes from joerg.

cygwin support.

file supfilesrv.c was added on branch matt-mips64 on 2007-07-20 16:39:07 +0000

cygwin support.

From Anon Ymous:
- add __unused
- fix volatile

rename clog to sup_clog.  (ugh.  we don't even have clog())

rename salloc to estrdup.

Coverity CID 621: Remove dead code.

Coverity CID 893: Check the pointer for NULL before using anyway, although
in the current situation it cannot happen.

provide a declaration for crypt(). Casting to char * will not work for
64 bit OS's.

Convert from tmpnam()/open() -> snprintf()/mkstemp(); the latter
avoids a linker warning about the use of tmpnam().

check error return from malloc and bail.

s/the the/the/ (only in sources that aren't regularly imported from
elsewhere).

Replace the statfs() family of system calls with statvfs().
Retain binary compatibility.

tabify

debian bug id "sup 1.8-8, bug #175327" - temporary file symlink race

use readlink with bufsize - 1; approved thorpej.

De-lint a bit.

Cleanup, part 2:
Remove 'register'. ANSIfy. indent(1). Static -> static.
Change some ``#include <header.h>'' to ``#include "header.h"'' for
local headers.
Fix function declaration mistakes uncovered by ANSIfication.

Cleanup, part 1:
Remove sysent.h, unneeded.
Remove __P().
unifdef __STDC__
Remove some #if 0 parts.
Start ANSIfication.

make sup/supfilesrv IPv6 ready.  supfilesrv listens to single socket,
therefore, you will need two instances running for dual stack support
(one with -4 and one with -6).

comment or delete text after CPP directives.

Pull up revision 1.19 (requested by mycroft):
  Always do the errno indirection hack, so that non-threaded
  libraries get the right errno value when linked with -lpthread.
  This means "always include <errno.h> and never declare errno
  yourself".

Nuke `extern int errno;' in code we compile with -Wstrict-prototypes.  We get
the correct definition from errno.h.

Add libwrap support to supfilesrv, as annnounced 2 weeks ago on tech-userlevel,
conditioned by #ifdef LIBWRAP (on by default).
I renamed '-l' (the 'live' mode) to '-d' and '-l' is now used to enable
logging of successfull connections, to be consistent with what other NetBSD
daemon use.
These changes are on on sup2.fr.netbsd.org since 2 weeks.

Pullup copyright text corrections.

Software_Distribution => Software.Distribution.

Use S_IS*(), not S_IF*.

Cleanup unsigned char -> char and #if __STDC__ -> #ifdef __STDC__
inconsistencies

- add $NetBSD$
- remove all $Log$ instances and the extra logs caused by our local changes.

Avoid coredump in svrfinishup.

compare only the prefix "nfs", not the whole word, so we match "nfs3" too.

64 bit patches (mostly long -> time_t) from Matthew Jacob (?)
sup now works on the alpha!

- add missing prototypes.
- fix function call inconsistencies
- fix int <-> long and pointer conversions
It should run now on 64 bit machines...

- for portability make sure that we never use "" as a pathname, always convert
  it to "."
- include sockio.h if needed to define SIOCGIFCONF (for svr4)
- use POSIX signals and wait macros
- add -S silent flag, so that the client does not print messages unless there
  is something wrong
- use flock or lockf as appropriate
- use fstatfs or fstatvfs to find out if a filesystem is mounted over nfs,
  don't depend on the major() = 255 hack; it only works on legacy systems.
- use gzip -cf to make sure that gzip compresses the file even when the file
  would expand.
- punt on defining vsnprintf if _IOSTRG is not defined; use sprintf...

To compile sup on systems other than NetBSD, you'll need a copy of daemon.c,
vis.c, vis.h and sys/cdefs.h. Maybe we should keep those in the distribution?

- runio fails when result != 0 not only < 0
- print vis-encoded file in the scanner.

- Don't use system(3) to fork processes. It is a big security hole.
- Encode the filenames in the scan files using strvis(3), so filenames
  that contain newlines or other weird characters don't break the scanner.

Changes to write ascii timestamps in the when files.
Looked into making it 64 bit clean, but it is hopeless.
Added little program to convert from the old timestamp files
into the new ones.

Changes from nate for gzip'ed sup

Close misbehaving connections instead of exiting.

use daemon() to put supfilesrv into daemon mode...

Remove netcrypt.c. Remove unneeded files. Cleanup make.

initial import of CMU's SUP to NetBSD
