mrg 1a8c7604f4 initial import of the new virtual memory system, UVM, into -current. 
UVM was written by chuck cranor <chuck@maria.wustl.edu>, with some
minor portions derived from the old Mach code.  i provided some help
getting swap and paging working, and other bug fixes/ideas.  chuck
silvers <chuq@chuq.com> also provided some other fixes.

this is the rest of the MI portion changes.

this will be KNF'd shortly.  :-)

cgd b92943e80a update to match (now-fixed) libc rules for strchr and strrchr. 
Brokenness pointed out by Matthias Drochner.

drochner 7e5c045bb6 remove prototypes for deprecated index() and rindex() 1998-01-23 12:56:39 +00:00
drochner 8968860bab add prototype for index() 1998-01-22 15:42:24 +00:00
cgd 4369378a6c add rules like those in libc to build strchr() and strrchr() (the latter 
is being added to libkern by this commit).  remove strchr.c from
archs' Makefile.inc files to go along with this.  (If an arch has
a .S version, it should be copied down and added to the apropriate
Makefile.inc.)

scottr d8f027887d If the send routine returns an error (-1), wait and retry using the same 
backoff mechanism we use for receiving the response.  This is particularly
helpful when we have transient errors on transmit, e.g. a very busy
network or router.

gwr f5bbc0b3ec Copied from src/lib/libc/net/inet_pton.c 
and adapted for kernel and libsa use.
 1997-12-12 20:14:01 +00:00
gwr 2031003c9b Oops - forgot to set netmask=smask 1997-12-10 20:38:37 +00:00
gwr ecd43c7870 Request the "gateway" parameter and use its contents 
to determine our gateway and subnet mask, consistent
with what is done by nfs_mountroot.
 1997-12-10 20:19:00 +00:00
mark 0053558a70 Fix a glaring bug in the assembly stubs for memcpy() and memmove() that 
meant the src address was being returned rather than the dst address.
Spotted by Chris Demetriou.
 1997-11-22 03:27:12 +00:00
gwr 5e82d82867 Pass down the values of: AR NM RANLIB 
(Fixes PR#4426 from SAITOH Masanobu)
Also pass down LORDER TSORT.
 1997-11-04 21:18:24 +00:00
gwr 0919e2346b Use LORDER, TSORT 1997-11-04 20:33:11 +00:00
lukem 3acbcabd91 use COPTS instead of CFLAGS (entry currently commented out) 1997-10-26 22:08:38 +00:00
mjacob 23a59f497a Add missing NULL define for KERNEL case and prototype into libkern.h. 1997-10-24 18:10:30 +00:00
chuck cf924e3bc0 add memchr() to libkern 1997-10-24 15:32:24 +00:00
cjs 4b97411a80 Change sd.transparent to sd.compressed, so that we default to non- 
compressed mode when we zero out the structure. Check_header() now
does not force us to uncompressed mode if we read no data (EOF);
it leaves the default, so that if we check at the end of a file,
we don't set the file to uncompressed mode and blow up later lseeks
on it.

mark 680595e7c3 Fix extra 'S' character typo that resulted in the condition codes being 
incorrectly internally on certain divides.
Handle the case where the internal result appears negative. This condition
can occur when dividing MIN_INT by certain values.

bouyer 7a337eca27 Ops, forgot to 'cvs add' theses. Pointed out by enami tsugutomo. 1997-10-12 13:27:59 +00:00
scottr c49762b3d3 Implement assembly byte-swap functions. 1997-10-11 04:28:40 +00:00
bouyer 6ab3092b11 Add byte-swapping functions (bswap16, bswap32, bswap64) to libkern. 
Only assembly version for i386 bswap16 and bswap32 for now (bswap64 uses
bswap32). Contribution of assembly versions of these are welcome.
Add byte-swapping of ext2fs metadata for big-endian systems.
Tested on i386 and sparc.

drochner b65a5212c3 Save some bytes by keeping the number of byteswaps minimal. 
Allow to switch off UDP checksum generation and check via compile time
option (for the really desperade).
 1997-09-17 16:30:51 +00:00
drochner 74c59c27a2 Keep a copy of the original BOOTP bp_siaddr field, in case we want to 
use it later for TFTP.

drochner 9f58a1a9bb fix printf() format warnings in debug output 1997-09-17 16:24:00 +00:00
drochner 93bb01fe6d -Wall fixes 1997-09-06 13:57:14 +00:00
drochner 616ee86daf -add DHCP support - this option also extends the vendor extension area 
to 312 bytes (The classical 64 bytes are likely to be too small if a
  rootpath is transferred.)
-make CMU vendor extension support optional
-remove code handling domain name/server (unneeded for boot code)
- -Wall fixes in debug code
 1997-09-06 13:55:56 +00:00
drochner 25c68ee4f2 Remove this relict, it's not needed anymore. 1997-07-22 17:51:51 +00:00
drochner bcf29dc4be Don't use "if_ether.h", it's not used. 1997-07-22 17:50:37 +00:00
cgd 6ac982f2a0 mark prototypes for static inline functions as possibly unused (with 
__attribute__ ((unused))), to avoid generating warnings when compiling
without optimization but with most ports' default warning flags.
 1997-07-07 22:45:34 +00:00
drochner 64cd693ada Don't use private copy of old netinet/if_ether.h. 
Use <net/if_ether.h> for ethernet specific definitions, and insert private
definitions for ARP if needed. (The new ARP macros in <net/if_arp.h> are
not used because they create larger code, and we really don't need more
than ethernet/ip support here.)
 1997-07-07 15:52:49 +00:00
drochner a8ac47dd1b Fix syntax error which appeared #ifdef DEBUG ("end[]"). 
Simplify the heap location stuff.
 1997-07-04 18:47:25 +00:00
drochner d9fbb6e1eb Catch errors from underlying reads, ie where oread() returns -1. 
(Original code used fread() which never returns -1, so this case was
not handled.)
 1997-07-04 18:45:11 +00:00
thorpej fee80fcee9 - Fix ZMAGIC image loading. 
- Deal with stripped kernels.
- Let machine-dependent code frob the start address.
- General cleanup.
From Matthias Pfaller <matthias@netbsd.org>
 1997-06-28 07:17:56 +00:00
drochner a1d00666ac Allow to define the location of the heap at runtime #if HEAP_VARIABLE. 
That helps to test libsa code in user space.
 1997-06-26 19:17:40 +00:00
drochner 96dde15c3f Don't define STANDALONE here, it is not used by sys/lib/libsa code. 
Port dependant code depending on it must define it in its own Makefile.
 1997-06-26 19:14:53 +00:00
drochner ed2ca9f1fa Avoid user space headers for standalone programs. 
Don't use sys/lib/libkern or sys/lib/libz if not standalone
 (ie, user space test programs).
 1997-06-26 19:11:30 +00:00
thorpej a2694f54d8 Don't run off the end of the format string if the caller botched for 
format modifier.  Pointed out by Daniel G. Pouzzner in PR #2633.

drochner f504cf88e8 Conditionally compile without symlink support (#ifdef NFS_NOSYMLINK). 
Saves 708 bytes (i386). (close pr misc/3335)
