340
---------- Things I thought Linus had for a while and not merged ----------------
341
 
342
 
343
---------- Things pending from other people -------------
344
 
345
o       Improved IPX support for lwared.
346
o       Decnet pre pre pre pre pre Alpha 0.0.
347
o       Chase Donald for new drivers, get people to sort out what net
348
        drivers should cease to be 'Alpha'.
349
o       IPX PPP support
350
o       IP multicast bug fixes
351
 
352
---------- Things pending for me to merge --------------
353
 
354
o       AF_UNIX garbage collect code
355
o       Faster closedown option for heavy use sites (me)
356
o       Tom May's insw_and_checksum()
357
o       SPARC patches [Dave] [partly in]
358
 
359
--------------- Things That Need Doing Before 1.4 ------------------
360
 
361
o       Clean up RAW AX.25 sockets.                     [Sorted by skb_clone change]
362
o       Finish IPIP bug fixes                           [Done hopefully]
363
o       Multicast routing                               [Nearly right]
364
o       PPP/IPX
365
o       IPX for Lwared
366
o       SKIP                                            [Available in user mode]
367
o       AX.25/NetROM locking changes
368
o       insw_and_csum
369
o       AF_UNIX fd passing
370
 
371
-------------------------- Bugs to fix ------------------------------
372
 
373
o       signal interrupting a unix domain connect can occasionally hang the
374
        machine ??
375
o       TCP socket cache gets things wrong very very occasionally under high
376
        load.                                           [TRYING THINGS]
377
o       AX.25/NetROM needs more locking.
378
o       NFS flow control is needed with the new multirequest NFS support.
379
o       Need to be able to turn off the intelligent arp refreshing as it's not so
380
        hot over AX.25 and upsets some people with very dumb ISDN bridges.
381
o       Matti Arnio's TCP problem.
382
o       Should unix domain connect never block ?
383
o       Sort out kerneld getting things right.
384
 
385
0.2
386
---
387
o       Fast checksum/copy on outgoing TCP
388
o       Add tty support to sonix driver.
389
o       PPP for Sonix ISDN.
390
o       Screend loadable firewall module
391
o       AXIP                                            [AVAILABLE IN USER MODE]
392
o       Finish merging the bridge code                  [LEAVE POST 1.4]
393
o       Finish 802.2 Class I code to be compliant to the oddities of 802.2
394
o       Tidy BPQ support to use a bpqip tunnel device
395
o       Kill off old ip_queue_xmit/ip_send stuff.
396
o       Remove kernel RARP and replace with user mode daemon.
397
o       Throw out existing firewall ioctl()'s and use a single table load.
398
o       SPARC merge
399
 
400
0.3
401
---
402
o       802.2 Class 2 services (eg netbios).
403
 
404
Possible projects for victim^H^H^H^H^Holunteers
405
 
406
 
407
2.      Verifying all the error returns match the BSD ones (grotty job I
408
wouldn't wish on anyone).
409
 
410
3.      'Fast Retransmit'. This is a TCP algorithm extension BSD uses. If
411
you see about 3 acks in a row that are for the same 'old' value. You resend
412
the frame following the ack. (The assumption being that the acks are
413
because a single frame in the data stream has been lost). Given a
414
mathematician with some queue theory you can show this allows you to
415
lose one frame per window full of data without measurable speed loss.
416
 
417
4.      RFC1323. These are the extensions for very fast nets.
418
RFC1323 will be useful for Linux talking to systems over 100 Mb/sec
419
Ethernet and over ATM as it allows large windows and protects from some
420
potential high speed TCP problems.
421
 
422
6.      Delayed ack. This is mostly supported but not actually set up and
423
used yet. Basically ack frames are held back 1/10th of a second in the hope
424
that two acks can be merged into one or for interactive use the ack can
425
piggyback on the next character typed (great improvement on 2400 baud
426
modems). Johannes Stille did some work on this about 0.99.13 but it never
427
got merged in. [Pedro Roque]
428
 
429
7.      One on my tempting project list. Add an extra (unofficial - but so
430
is SLIP6) SLIP mode that does packet data compression [maybe use the code
431
from term].
432
 
433
9.      Implementing streams. Not as a blind slow SYS5.4 style copy but actually
434
working out how to do it so it runs like greased lightning. Quite a big
435
problem. [See the LiS project]
436
 
437
10.     Frame Relay/WAN/ISDN drivers [I'm working on the sonix EuroISDN board
438
driver but that's for an internal project and its general release is still
439
a maybe (so is finishing it ;))][Jim Freeman is working on Frame Relay as is
440
Mike McLagan][Fritz Elfert is doing the isdn4linux kit].
441
 
442
11.     IP over SCSI.
443
 
444
14.     Bidirectional PLIP. Also PLIP for the newer style parallel ports.
445
 
446
15.     802.2LLC and thus Netbeui sockets. Becoming less important since the
447
rumour is microsoft are phasing out netbeui for netbios/IP. Microsoft have
448
gone for netbios/funny-ipx-variant it seems in Win95, but TCP is selectable.
449
 
450
16.     X.25. This is one for a real head case with far too much time on
451
their hands. [Provisionally taken]
452
 
453
17.     PPP multilink. Another nasty job.
454
[In progress]
455
 
456
18.     Implement swIPe under Linux.
457
[Reportedly in progress]
458
 
459
19.     IPv4 IP-AH and IP-ESP.
460
[Taken]
461
 
462
20.     SKIP IP security using ENskip-0.10 - started
463
[Abandoned]
464
 
465
21.     T/TCP support.
466
 
467
BTW: Don't let the magic words 'kernel programming' worry you. Its like DOS
468
- you make a mistake you have to reboot. You do at least get dumps and a
469
kernel logger that is reliable. There is now a loadable module allowing
470
use of gdb on the kernel (no breakpoints though!). No magic involved.
