21/09/09 08:47:00 Sam Jansen <sam@wand.net.nz>

	Version 0.5.1.

	Miscellaneous bug fixes and compile fixes from Florian Westphal,
	including gcc 4.4.0 support.

19/11/08 12:08:00 Sam Jansen <sam@wand.net.nz>

	Version 0.5.0.

	Fix bug reported in ns-3
	(http://www.nsnam.org/bugzilla/show_bug.cgi?id=368) -- sysctl problem.

	Change from Florian to better support getsockname/getpeername: new
	interface with better support.


20/10/08 18:24:00 Sam Jansen <sam@wand.net.nz>

	Version 0.4.1

	Fix compile error with new GCC (bug 334).

	Fix include/asm problem (bug 353).

	Rework FreeBSD5; use the correct checksum file, make code more
	consistent and maintainable, remove old unused code, add wakeup()
	support.

	Rework Linux stacks, making code more consistent and maintainable.
	Remove old references to things no longer used (e.g. electric fence).
	Modify sysctls to be only defined in one place (sysctl.c).

	Add wakeup() support to lwip-HEAD. Fix socket accepts, the accept list
	i snow a member of the listening socket rather than the stack.

	Fix bug in ns-2 agent reported by Lawrence Brakmo: incorrect logic for sending.
	Add Linux 2.6.26 support to the ns-2 agent.

	Add correct wakeup() support to OpenBSD3.

	Remove old scons version, upgrade to new version.

	Big build system rework; SConscript are now more declarative and much
	more concise. Move build rules into the top-level SConstruct; also all
	configure functionality there. Clean up a lot, now dependency checking
	is correct for globalised files. Also fix the 32-bit/64-bit build
	problems, this should all work seamlessly now. Also allows the user to
	specify a compiler and C/Link flags in a top-level "custom.py" file.

	Add a simple test framework for NSC. Include some simple TCP stream
	and interface tests.

	Minor bug fixes (e.g. error returns) due to the testing.


26/08/08 11:13:00 Sam Jansen <sam@wand.net.nz>

        Version 0.4.0.

	Incorporate many changes from the Google Summer of Code.

	Linux 2.6.26 included.

	New version of the globaliser.

	Support 64-bit compilation for Linux 2.6.18, 2.6.26.

	Many bug fixes over this time.

	Thanks to the GSOC student Florian Westphal for this many improvements
	to the NSC.


09/01/08 20:49:00 Sam Jansen <sam@wand.net.nz>

	Version 0.3.0

	Incorporate changes from Google.

	Fix typo in INSTALL file.

	Allow specifying globaliser flags in SConscript files.

	Add Linux 2.6.18. Add support for packet schedulers, and basic "tc"
	support to configure this.

	Change names of shared libraries to always include version
	information.

	Enable checksums in all stacks. This makes the stacks more consistent,
	easier to interface with, and reduces the amount of changes required.

	Some refactoring of internal interfaces to make them more consistent.
	Make things more const correct, use the right types for addresses,
	etc.

	Change FreeBSD 5.3's stack interrupt handling; now it does not need to
	call back into the simulator (the end effect is the same).

	Changes to the simulator / stack interface. New support for saying
	when the NIC has finished sending, old interfaces tidied up and some
	removed. Add new function to send textual commands to a stack.

	Fix bug in NSCAgent::wakeup() -- only reschdule timer if its already
	fired.

	Tidy up stack registration code with a macro.

	Add NSC_VERSION macro in stack/simulator interface.

	Globaliser: Update to 1.1.0. See globaliser-specific readme file.



23/03/06 01:33:16 Sam Jansen <sam@wand.net.nz> [1187]

	* 900/nsc/linux-2.6/nsc/support.c:
	Minor change that makes the receivers advertised window grow in the same
	fashion as what we measured on the emulation network. We do this by allocating
	different size skbuffs in our simulation driver code.
	

22/03/06 23:35:26 Sam Jansen <sam@wand.net.nz> [1184]

	* 900/nsc/linux-2.6/nsc/support.c:
	BUGFIX: Fix jiffies: was increasing it way too fast...

	* 900/nsc/linux-2.6/nsc/support.c:
	* 900/nsc/linux-2.6/nsc/unimplemented.c:
	Fix bugs in Linux2.6 which meant it didn't select as big a window as it should. The
	same bugs have been fixed in Linux 2.4 quite some time ago.
	
	implemented.c: fix __get_free_pages to return a greater amount of memory
	unimplemented.c: Set jiffies to 1, so timestamps always work. Set num_physpages to
	    (128*1024), this along with __get_free_pages fixes memory size selection for
	    TCP buffers.
	
	Also a few changes to debugging output, make it a little less verbose.
	
	

16/03/06 23:12:44 Sam Jansen <sam@wand.net.nz> [1162]

	* 900/nsc/openbsd3/support/interface.c:
	Make the openbsd stack handle received packets right away, rather than waiting
	for the next timer interrupt. I *think* this is more realistic.
	
	Note that this will change the results of all openbsd sims now, so I should
	really re-run everything openbsd. Hrm.
	

04/03/06 08:00:09 Sam Jansen <sam@wand.net.nz> [1080]

	* 900/nsc/openbsd3/support/sim_support.cpp:

	was supposed to.
	

04/03/06 07:26:13 Sam Jansen <sam@wand.net.nz> [1079]

	* 900/nsc/freebsd5/support/sim_support.cpp:

	* 900/nsc/openbsd3/support/sim_support.cpp:
	* 900/nsc/openbsd3/support/socket.c:

20/02/06 23:55:29 Sam Jansen <sam@wand.net.nz> [1044]

	* 900/nsc/lwip-HEAD/src/global_list.txt:

	Work on ns/agent/nsc.cc:
	* Look for MSG_EOF and set close_on_empty_
	* Add close_on_empty_ flag
	
	Make Linux 2.6 work with optimisations. Fix malloc_sizes, addd init that comes
	from mm/slab.c (kmem_cache_init). Not the full routine, just some of it.
	
	Fix up profile-globaliser.sh.
	

03/02/06 04:41:50 Sam Jansen <sam@wand.net.nz> [1040]

	* 900/nsc/profile-globaliser.sh:
	Add script to profile the globaliser: looks at file size and shared lib
	size with different NUM_STACKS settings.
	

19/01/06 16:13:07 Sam Jansen <sam@wand.net.nz> [1025]

	* 900/nsc/freebsd5/support/support.c:
	Initialise &#34;ticks&#34; to 1. 0 can be bad for various reasons, such as setting
	your timestamp to 0 in the tcp option, various stacks interpret that in
	different ways. Setting it to 1 is more realistic.
	

19/01/06 16:12:12 Sam Jansen <sam@wand.net.nz> [1024]

	* 900/nsc/openbsd3/support/support.c:
	Check for finding sysctl function, return error if no function found.
	

16/01/06 18:26:00 Sam Jansen <sam@wand.net.nz> [1018]

	* 900/nsc/freebsd5/support/unimplemented.c:
	Fix memory leak.
	
	uma_zalloc_arg was not calling the dtor or fini routines for the zone. This
	ended up meaning MbufClust-allocated 2048 size bits of memory were not being
	freed.
	

09/01/06 11:03:34 Sam Jansen <sam@wand.net.nz> [1011]

	* 900/nsc/openbsd3/SConscript:
	Fix voodoo undefined reference problem.

	* 900/nsc/freebsd5/support/support.c:
	* 900/nsc/linux-2.6/nsc/sim_support.cpp:
	Support returning how much was written in FreeBSD5. Perhaps with some minor
	bugfixes.
	
	Make Linux 2.6 not print out sysctl info and assert that there was no error
	when performing a sysctl.
	

13/12/05 16:39:10 Sam Jansen <sam@wand.net.nz> [1004]

	* 900/nsc/linux-2.4/nsc/globals.c:
	* 900/nsc/linux-2.4/nsc/implemented.c:
	* 900/nsc/linux-2.4/nsc/sim_support.cpp:
	Fix a bug with the memory being &#34;reported&#34; being too low, so TCP was selecting
	a small buffer size.
	

13/12/05 16:02:47 Sam Jansen <sam@wand.net.nz> [1003]

	* 900/nsc/ns/agent/nsc.cc:
	Fix up auto_conf stuff.
	

24/11/05 05:20:42 Sam Jansen <sam@wand.net.nz> [975]

	* 900/nsc/ns/agent/nsc.cc:
	Add autoConf_ NSC stack directive. eg.
	
	    Agent/TCP/NSC set autoConf_ 0
	
	    (it defaults to 1 (true))
	
	It only makes sense to set globally like that. Once a stack is created it does
	not use the variable anymore.
	
	It means the window_ and packetSize_ are not bound, hence they are not set
	by ns-2 at startup.
	

23/11/05 01:25:50 Sam Jansen <sam@wand.net.nz> [945]

	* 900/nsc/globaliser/test/array.c:

23/11/05 01:17:07 Sam Jansen <sam@wand.net.nz> [944]

	* 900/nsc/openbsd3/support/support.c:
	Make OpenBSD no longer output its copyright notice.

	Add virtual destructors to interface. This means everything needs to be
	rebuilt. No change in functionality though.
	
	Add an assert to lwIP to make sure the MTU is 1500, it is all that stack
	supports.

	* freebsd5/support: Fix sysctl to return the right value. Implement
	buffer_size.
	
	* ns/agent/nsc.cc: Re-enable buffer_size. Still need some way to
	enable/disable this functionality.
	
	* linux-2.4/nsc: Add setting of more sysctl values and understand/
	parse more sysctl names (tcp_rmem and so on). Fix some type warnings.
	
	* linux-2.6/include: Turn CONFIG_X86_WP_WORKS_OK off so copying to
	userspace is simplified. I'm fairly sure this isn't important now, but
	it seemed like it was earlier.
	
	* linux-2.6/nsc: Implement __copy_to_user_ll, port linux-2.4 sysctl
	changes over, fix nsc_g_diagnostic naming, remove __get_user_* funcs.
	Implement some proc handlers. Initialise current-&gt;thread_info
	properly. Fix debug output of nsc_sysctl_a(). Add getuser.S with
	modifications so it doesn't check stuff.
	
	* openbsd3/support: Add error checking to buffer_size.
