1.0 -> 1.1
- uses fdev stuff now and thus supports many more NICs (built with
(vortex, tulip, hp-plus, and ne2000)
- stores netmask in hostorder consistantly now Used to always send
to the gateway, duh!
- called netbooty now
1.1 -> 1.2
- called netboot again
- uses the OSKit bootp library
- cleanup, flux->oskit, other renaming
1.2 -> 2.01
- Got it to be a multiboot kernel, instead of a BSD one.
This simplifies the code and will enable us to work on Linux
in the future.
2.01 -> 2.02
- Made it boot multiboot kernels now, not BSD ones.
This is mainly so we can pass them arbitrary command lines, which
will eventually include a "return address" so we can regain control
after the booted kernel exits.
A disadvantage is that thre isn't a multiboot-boot-adaptor yet, so
we can't glob a bunch of bmods together into a multiboot image like
we can for BSD images.
- Various cleanup, bugfixes, and reorganization
2.02 -> 2.1
- Implemented the regain-control feature.
- Implemented simple hostname lookup.
2.1 -> 2.2
- Fixed the bug with using kernels bigger than approx 16M.
- Fixed the random memdebug "bad head magic" and LMM trashing,
I think (by getting mem_lock from libkern instead of libc).
- Minor appearance tweaks.
2.2 -> 2.3
- Fixed command-line parsing to not thing everything after
the last slash is the kernel name. Therefore it now works to
have slashes in your command line like PATH=/bin:/usr/bin
2.3 -> 2.4
- Fixed driver.c to use the new com_queue implementation of
oskit_queue_t instead of the `struct packet_queue' thing,
which was actually a stack(!). This apparently fixes the
hangs after the "Root server: 155.99.123.45, dir:..." line
that were happening to Roland and me. It also prevents
`net_receive' from doing any mallocing.
- Removed bogus check that was preventing LILO from booting
netboot. LILO wasn't passing any args.
- Print oskit_error_t's as hex.
- Various cleanup.
2.4 -> 2.5
- Various updates to deal with new commandline format, which
is like:
progname [<booting-options and foo=bar> --] <args to main>
- As a result, we are now responsible for providing argv[0],
and use the `file' part of the ip:/dir/file pseudo-URL.
2.5 -> 2.5.1
- Fixed to not call strlen(0). This is bad. More specifically,
if the program before us stored a bunch of poo at addr 0, then
we can blow our stack in build_cmdline, which allocates
a dynmaic stack array.
2.5.1 -> 2.6
- Added NFS readahead code
2.6 -> 2.6.1
- Added query for nfs readahead from environment
2.6.1 -> 2.6.2
- Fixed ever-incrementing 'input' variable with leading spaces
- Changed main to return int (eliminate compiler warning)
Added fixes from Klaus Espenlaub <espenlaub@informatik.uni-ulm.de>:
- Pass the multiboot magic number in register %eax.
- Add code to properly number the IP packets sent out.
- Pass in the buffer size to parse_cmdline (for future robustness)
- When checking the multiboot image, replace panic()s with
a failure return so we can recover.
