initialization. This adds an interface which makes it easier to
control the BSD stack from user code. The BSD stack initialise uses
it. It is a sort of `function' interface for an ifconfig
command.
I also added support for attaching and removing interfaces. With hot
swap PCI comming online support for hot swap PCI will be an important
factor in "state of art" RTOS's. This is also part of a general move on
my part to allow RTEMS to be configured at runtime by calls rather than
table driven at initialisation.

that contains:
* Removes remaining (now illegal) references to $(SRC) from a couple of
Makefile.ams
* Removes duplicate AC_CONFIG_SUBDIRS macro from c/configure.in
* Moves ENABLE_LIBCDIR into RTEMS_PROG_C[C|XX]_FOR_TARGET (hides LIBCDIR
from most configure scripts, i.e. LIBCDIR becomes less visible)
* Adds RTEMS_PROG_C[C|XX]_FOR_TARGET and RTEMS_CANONICALIZE_TOOLS to
libbsp/*/configure.ins (A minor bug in previous implementations, which
only has an impact when switching to GNU/Cygnus canonicalization)
* Cleans up several bogus comments.
* Removes MKLIB
* Switches the version number to 4.5.0 (for testing version number
handling)

that contains the automake files for libnetworking plus a couple of
minor fixes. [Now only one unused/unsupported Makefile.in remains
(./c/src/lib/libbsp/hppa1.1/pxfl/Makefile.in).]

Notes:
* I have tested this one by building all BSPs for m68k, powerpc, sh and
unix with toolchains built since last weekend.
* I did not touch libnetworking's directory layout.

report by Nick.SIMON@syntegra.bt.co.uk:
TFTP uses UDP and UDP packets are prime targets for getting dropped when
the network gets busy. I want the number of retries quite large in my
application. I see that PACKET_REPLY_MILLISECONDS is, in fact, not
being used.

functionality. This puts RTEMS in near compliance with the network
functionality defined in the first draft of the EL/IX API. Comments
follow:
With the attached changes to the libnetworking/libc/Makefile.in, RTEMS
provides all the functions listed in section 4.14 of the EL/IX document
except:
socketpair
if_nametoindex
if_indextoname
if_nameindex
if_freenameindex
Some of the routines which get information from files may be of limited
use unless an application sets up the files somehow (TFTP/untar from
host, etc.), but at least RTEMS is pretty much fully buzzword compliant
with the networking section of the EL/IX API.

Patches against 1105 snapshot to add NTP server support to network
configuration/BOOTP.
|

EPICS needs a synchronized time-of-day clock. This patch is the changes
needed to get NTP server information from a BOOTP server.
This patch also adds NTP server information to the network configuration
structure, too.

<valette@crf.canon.fr> to add a port of the GoAhead web server
(httpd) to the RTEMS build tree. They have successfully used
this BSP on i386/pc386 and PowerPC/mcp750.
Mark and Joel spoke with Nick Berliner <nickb@goahead.com> on
26 Oct 1999 about this port and got verbal approval to include
it in RTEMS distributions.

report from Philip A. Prindeville <philipp@zembu.com>:
I was working on a device driver for a certain ethernet chipset that
occassionally wraps in its buffer, and causes a resulting mbuf chain
with only a few dozen bytes in the first mbuf of the chain.
I wouldn't have thought this would be a problem, until I ran some
stress tests that flooded the ethernet receiver with packets and
started to get panics here:
250
251 if (m->m_pkthdr.len < sizeof(struct ip))
252 goto tooshort;
253
254 #ifdef DIAGNOSTIC
255 if (m->m_len < sizeof(struct ip))
256 panic("ipintr mbuf too short");
257 #endif
258
259 if (m->m_len < sizeof (struct ip) &&
260 (m = m_pullup(m, sizeof (struct ip))) == 0) {
261 ipstat.ips_toosmall++;
262 return;
263 }
264 ip = mtod(m, struct ip *);
and the panic was at line 256. But if I #undef'd DIAGNOSTICS,
then the m_pullup() at line 260 does the right thing and the packet
ends up being processed just fine.
So I started wondering, (a) why was the test checking for
something that apparently wasn't a fatal condition but rather
one that is subsequently recovered from a couple of lines later
and (b) why panic as a diagnostic "aid" from a recoverable
condition rather than just (say) log a message to the console?
All of this seems overly severe for no reason that is readily
apparent to me.

now prototypes the malloc family in stdlib.h. This causes conflicts
with the way the network stack overrides the definitions of malloc.
As best I (being Joel) can tell, commenting stdlib.h out keeps the
files compiling and referencing the desired malloc/free but results
in more warnings.

The patch below actuallly consists of two patches:
1) moving librpc to c/src/librpc similar to what has been done to librtems++
2) reworked configure scripts, many safety and dependency checks added to
aclocal/*.m4 macros + configuration fixes.
To apply:
mkdir c/src/librpc
mkdir c/src/librpc/src
cp c/src/lib/librpc/*.c c/src/librpc/src
cp c/src/lib/librpc/Makefile.in c/src/librpc/src
mkdir c/src/librpc/include
mkdir c/src/librpc/include/rpc
cp c/src/lib/include/rpc/* c/src/librpc/include/rpc
patch -p1 < ../rtems-rc-19990820-7.diff
rm -rf c/src/lib/librpc
rm -rf c/src/lib/include/rpc
./autogen
The additional checks in aclocal/*m4 macros add rather restrictive, sometimes
unnecessarily restrictive constraints on the sequence of how macros can be
used in a configure.in script. Adding them has let my problems with some more
complicated configuration options vanish. Apparently some macros had not been
in the required order .

The old system would panic when the loopback interface was included as
part of the network initialation structures. With the printf you get an
message, but the interface is still properly initialized.

The main topic is replacing the hard-coded values for HAS_MP and
HAS_RDBG in custom/*.cfg with per-bsp configuration-time autoconf checks
(This is the patch I had mentioned before earlier this week).
CHANGES
* HAS_MP removed from custom/*.cfg, replaced with configuration time
autoconf check
* HAS_RDBG removed from custom/*.cfg, replaced with configuration-time
autoconf check
* NEW: c/src/make/bsp.cfg.in, takes configuration-time checked per-bsp
values (i.e. HAS_MP, HAS_RDBG), gets installed as
$(prefix)/<bsp>/make/bsp.cfg
* NEW: default.cfg includes bsp.cfg - this change is backward
compatible.
* IMPORT_SRC: apply VPATH instead for ts_386ex/i386ex subdirectory
Makefile.ins
* HACK: a bug in acpolish mis-handles addtions to makefile variables
which are enclosed in gmake conditionals:
c/src/lib/libbsp/m68k/ods68302/start302/Makefile.in
* Apply inline_dir, HAS_MP and HAS_RDBG for avoiding configuration of
unneeded subdirectories in various configure.in files.
* Several minor changes in Makefile.ins and configure.ins, wrt. to the
order of including *.cfg and defining Makefile variables
