	Up the stack size to cope with full DHCP initialization in
	init_all_network_interfaces().
	
2000-07-13  Hugo Tyson  <[e-mail]>

	* cdl/net.cdl: Add DHCP enable and interface-specific controls.

	* include/dhcp.h: New file: describe the DHCP APIs and behaviour,
	as well as some internal APIs that are also available.

	* src/lib/dhcp_support.c: New file: the surrounding management
	routines, a bit like network_support.c, which know about multiple
	interfaces and so on.

	* src/lib/dhcp_prot.c: New file: the interface-independent DHCP
	protocol machine, which is called from dhcp_support.c routines and
	init_all_network_interfaces() in network_support.c

	* include/bootp.h (struct bootp): Make the packet bigger if DHCP
	so that a mininal DHCP packet will fit.

	* src/lib/bootp_support.c (do_bootp): If no reply, fail gracefully
	and tidy up so that other interfaces can be upbrung.
	(show_bootp): Tell us a lot more about DHCP-specific info in the
	packet structure.
	(get_bootp_option): be aware of DHCP extensions to re-use file and
	sname fields for options.

	* src/lib/network_support.c (init_all_network_interfaces): Call
	do_dhcp() rather than do_bootp() if so configured, and initialize
	the per-interface DHCP state variables accordingly.

	* tests/dhcp_test.c (net_test): New test file that diddles the
	DHCP machine while doing a ping test.

2000-07-11  Gary Thomas  <[e-mail]>

	* include/netdev.h: Add single-inclusion fences.

	* include/sys/param.h: Add traced versions of splx() routines,
	selectable by a configuration option.

	* src/ecos/support.c: Rework splx() emulation routines to
	be more robust and realtime friendly.

	* src/lib/network_support.c (init_all_network_interfaces): 
	Add minimal support for PCMCIA based devices.

2000-07-04  Hugo Tyson  <[e-mail]>

	* include/bootp.h: Fix namespace pollution from "#define int32
	int" - it fights against application code too much.

2000-07-04  Jonathan Larmour  <[e-mail]>

	* cdl/net.cdl: Package requires CYGPKG_MEMALLOC

2000-06-26  Hugo Tyson  <[e-mail]>

	* tests/ping_test.c (net_test): Added use of the
	CYGPKG_NET_TESTS_USE_RT_TEST_HARNESS stuff now that the test
	passes (consequent on the change below); also use larger ping
	packets now that that is working also.

	* tests/tcp_echo.c (echo_test): Added use of the
	CYGPKG_NET_TESTS_USE_RT_TEST_HARNESS stuff now that the test
	passes (consequent on the change below).

2000-06-26  Hugo Tyson  <[e-mail]>

	* src/ecos/support.c (cyg_splnet): Use the scheduler lock and a
	mutex instead of disable-interrupts for SPLX type processing.  A
	mutex is used at splsoftnet because that is client threads - we do
	not want them to pre-empt the rest of the app.  This enables the
	real-time response testing for the EBSA285 to succeed (interrupts
	every 1mS, DSRs delayed by at most 2mS).

2000-06-23  Hugo Tyson  <[e-mail]>

	* src/ecos/support.c (cyg_net_mbuf_alloc, cyg_kmem_init): Align
	the mbuf pool to MSIZE [128] bytes.  That way dtom() works, nasty
	though it is.  That's needed for ip reassembly in ip_input.c, when
	dealing with large icmp-layer packets eg. ping -s 2000 ...

2000-06-21  Hugo Tyson  <[e-mail]>

	* include/lib/libkern/libkern.h: Do not define assert multiple
	times; guarded by __ECOS.

	* include/sys/param.h (MAX,MIN): Only define if undef.

2000-06-21  Hugo Tyson  <[e-mail]>

	* cdl/net.cdl: Build the new tests; in fact build them
	unconditionally.

	* src/lib/network_support.c (init_all_network_interfaces):
	Initialize loopback device[s] using init_loopback_interface(),
	providing a sensible default route et al.  Multiple devs: lo1 will
	be 127.0.*1*.1, and so on; class C netmasks will be used.

	init_all_network_interfaces() is also made thread-safe as well as
	idempotent, so other threads (or daemons) can call it to make sure
	the net is up.

	* src/ecos/support.c (cyg_net_init): Add a call to loopattach() if
	there are indeed loopback dev(s) configured.  This does the
	equivalent of the init of a device from the table, but simpler.

	* tests/udp_lo_test.c (udp_server): New testcase...
	* tests/tcp_lo_select.c (tcp_server): New testcase...
	* tests/tcp_lo_test.c (tcp_client): New testcase...
	* tests/ping_lo_test.c (net_test): New testcase, unconditionally
	built loopback device test.  Will run on platforms with no network
	interfaces.

2000-06-19  Nick Garnett  <[e-mail]>

	* src/ecos/support.c:
	* include/netdev.h:
	Converted to use of new table construction mechanism.

2000-06-16  Jonathan Larmour  <[e-mail]>

	* include/bootp.h: Remove RCS id tag
	* include/netinet/ip_auth.h: Ditto
	* include/netinet/ip_fil.h: Ditto
	* include/netinet/ip_fil_compat.h: Ditto
	* include/netinet/ip_frag.h: Ditto
	* include/netinet/ip_nat.h: Ditto
	* include/netinet/ip_proxy.h: Ditto
	* include/netinet/ip_state.h: Ditto

2000-06-15  Nick Garnett  <[e-mail]>

	* src/sys/kern/sockio.c: Added cyg_selinit() calls to bad_socket()
	and bsd_accept() functions.

	* src/ecos/support.c (cyg_tsleep): Changed tests on wakeup from
	semaphore waits to enable return of EINTR results.

2000-06-09  Nick Garnett  <[e-mail]>

	* src/sys/net/if_loop.c: Substituted sprintf() for a straight
	strcpy() when initalizing if name. This currently only works for
	one loopback interface. However, there seems little need to have
	more than one.

	* src/sys/kern/sockio.c (bsd_select): Added select support.

	* include/sys/time.h: Moved timeval structure definition to
	isoinfra time.h header since it is needed by the select() API.

	* include/sys/select.h: Added option to use fileio select
	mechanism if it is present.

	* src/ecos/support.c (cyg_net_init):
	Added code to bring up the loopback interface. This is to help
	with testing on platforms without network hardware.

2000-06-08  Hugo Tyson  <[e-mail]>

	* include/netinet/ip_var.h: Export ipforwarding as well as
	ip_defttl for monitoring applications.

2000-06-07  Nick Garnett  <[e-mail]>

	* tests/tcp_echo.c: 
	* tests/socket_test.c: 
	* tests/server_test.c: 
	* tests/ping_test.c: 
	* tests/nc_test_master.c: 
	* tests/nc_test_slave.c: 
	* tests/ftp_test.c:
	Removed dependence of these programs on STDIO. For most this
	simply required the use of a diag_printf() based perror() clone is
	CYGPKG_LIBC_STDIO is not defined. For server_test is also required
	the substitution of sprintf() with some more primitive string
	functions.

	* src/sys/netinet/ip_input.c: Rewrote inet_ntoa() to not use
	sprintf(). This was the only place in the TCP/IP stack that was
	dependent on a STDIO function. We really should avoid building
	this kind of casual dependency into the code.

	* src/sys/kern/sockio.c: This new file contain code to support the
	fileio package. So far only a few of these functions have actually
	been tested.

	* include/sys/kernel.h (time): The time variable clashes with the
	C library time() function. To prevent this it is renamed ktime,
	and a #define allows "kernel" code to continue accessing it as
	time.

	* src/ecos/support.c: Added definition for ktime variable, as
	described above. I could not find any definition for struct
	timeval time. I have a nasty suspicion that it was using the
	time() function - let's hope that no code that actually uses this
	has been run.

	* src/lib/bootp_support.c: Another substitution of a diag_printf()
	based perror() clone when STDIO is absent.
	
	* include/sys/bsdtypes.h: This is the original
	include/sys/types.h. Renamed to avoid clashing with <sys/types.h>
	defined by the isoinfra package.

	* include/sys/types.h: Renamed to bsdtypes.h.
	
	* include/machine/limits.h:
	Various changes to make these headers play nicely with those
	defined in isoinfra package.

	* include/network.h: Added include of <pkgconf/system.h>. Fixed
	prototypes of functions here to match POSIX specifications.

	* cdl/net.cdl:
	Split list of files to compile into the common set plus those
	needed when the fileio package is present and those that are
	needed when it is absent.
	Added CDL to export our definitions to <sys/types.h>.
	

2000-05-31  Hugo Tyson  <[e-mail]>

	* src/lib/network_support.c (init_all_network_interfaces): Make
	this call idempotent - this is useful for reliable initialization
	of dependent subsystems.

	* include/lib/libkern/libkern.h: remove protos of random() and
	srandom() for they are not in fact provided.

	* cdl/net.cdl: Turn off CYGPKG_NET_TESTS_USE_RT_TEST_HARNESS by
	default - since not all tests currently pass. 

2000-05-12  Hugo Tyson  <[e-mail]>

	* cdl/net.cdl (CYGPKG_NET_TFTPD_THREAD_PRIORITY): New option,
	control the TFTPD thread priority.  These options are *all*
	CYGPKG_NET.  Yuk, sort 'em out later.

	* tests/tftp_server_test.c (tftp_test): Added use of the
	CYGPKG_NET_TESTS_USE_RT_TEST_HARNESS stuff, same as for the flood
	ping test.  This one passes (with the next change), so committed.

	* src/lib/tftp_server.c (tftpd_server): Cancelled some of the
	printouts as connections come and go *iff* the tests are set up to
	use the realtime-ness test harness.  This needs generalizing into
	proper control of the network's chattiness overall.
	(tftpd_start): Also added configury of the TFTPD thread priority.

2000-05-12  Hugo Tyson  <[e-mail]>

	* cdl/net.cdl: Add flood test below.  Also add option
	CYGPKG_NET_TESTS_USE_RT_TEST_HARNESS to decide whether to
	"Use real-time response test harness (if available)".
	Consequently moved the test build stuff forward out of the build
	flags area.

	* tests/flood.c (net_test): New file; performs a flood-ping (well,
	as fast as we can go) of the server(s) on the two interfaces.
	Also uses the real-time interrupt response verification stuff from
	the EBSA285 driver component.

2000-05-11  Hugo Tyson  <[e-mail]>

	* cdl/net.cdl: Add new utility (and harmless-by-default test)
	tests/set_mac_address.  You have to edit it to get anything
	damaging to happen.

	* tests/set_mac_address.c: New file added.  It uses SIOCSIFHWADDR
	to set the MAC address of any interfaces it has been told to.

2000-05-08  Gary Thomas  <[e-mail]>

	* include/machine/cpu.h: 
	* include/machine/cdefs.h: Add copyright boilerplate.

2000-05-05  Hugo Tyson  <[e-mail]>

	* include/arpa/tftp.h: Aargh.  Turns out that removing the align
	driective and retaining only the packed directive makes the
	original version work.  So, reverted.  Apologies for the wasted
	time.

	* src/lib/tftp_server.c (tftpd_read_file): Coupla warnings
	reduced, and reverted to match original tftp.h

	* src/lib/tftp_dummy_file.c (dummy_open): Removed use of
	undeclared malloc().

2000-05-04  Gary Thomas  <[e-mail]>

	* src/lib/tftp_server.c: 
	* src/lib/tftp_client.c: Adjust for changes in header structure.

	* include/arpa/tftp.h: Continuing problems with alignment on ARM.  
	Recourse is very bastardized structure, but it _does_ work.

2000-05-04  Hugo Tyson  <[e-mail]>

	* tests/tftp_client_test.c (tftp_test): Print out a coupla more
	things and test both interfaces if they exist - which does the
	same thing twice if the same server bootp'd both.  Changed the
	filenames to something more obvious.

	* cdl/net.cdl (CYGPKG_NET_TESTS): Build the tftp tests
	tests/tftp_client_test tests/tftp_server_test

	* src/ecos/support.c (cyg_kmem_print_stats): New function; prints
	info about memory usage for some tests to come.

2000-05-04  Gary Thomas  <[e-mail]>

	* include/arpa/tftp.h: Force packed alignment - required on some
	architectures.

2000-05-01  Gary Thomas  <[e-mail]>

	* src/lib/tftp_dummy_file.c: Adding very simple routines - just
	enough to test TFTP server.  This support will come from elsewhere
	in actual application environments (e.g. a real file system).

	* tests/tftp_server_test.c: 
	* src/lib/tftp_server.c: 
	* include/tftp_support.h: Flesh out TFTP server support.

2000-04-13  Hugo Tyson  <[e-mail]>

	* tests/tcp_echo.c (calibrate_load): Import better background
	thread loading algorithm with bugfix; if the initial HIGH limit
	was not large enough, it never got loaded enough.
