This release incorporates all fixes and changes made since the release of 2.10.1BSD in January 1989 as well as several missing pieces of 4.3BSD (the namei cache, tmscp driver, long filenames, etc.) Bug reports, technical questions: Report bugs using the standard sendbug format (see bugfiler(1)) WITH AN INDEX LINE OF "2.11BSD". General questions can be directed to Steven Schultz at [email protected]. At this time, contact by phone is not available due to a high degree of travel. If you're really desperate, print out a hardcopy example of the problem, and carefully mark your place with a picture of your favorite president, preferably a large denomination. Send it to me. Bug fixes will be posted to comp.bugs.2bsd. Archives may be requested from Steven Schultz by electronic mail. For an explanation of how unsupported this release is, read the the remainder of this and the "changes" document, and keep in mind that this activity is not what pays the mortgage each month. Credit where it's due: Paul Taylor of SUNY Oswego for volunteering to put 2.11BSD on his 11/73's back when it was known as 2.10.2SMS and fighting the beta test problems, proofreading and critiqueing the documentation. Terry Kennedy of St. Peter's College for final testing on a 11/70 and for putting together an 11/73 for me. Bob Karlicek of AT&T for loaning me his 11/73 (on the basis of an Internet developed acquaintance) to develop the TMSCP driver and related standalone support. Steven Schultz [email protected] Paul Taylor [email protected] Terry Kennedy [email protected] Bob Karlicek [email protected] In general: - The system hasn't been fit onto a non-separate I&D or machine without a floating point processor in a long time. Lots of overlay schemes need to be worked out; the floating point simulator in the kernel hasn't been tested; sendmail won't run on a non-separate machine, so bin/mail and ucb/Mail have to auto-configure not to use sendmail; csh is overlaid now even on a separate I&D machine, /lib/cpp is pushing the limit to handle all the #define'ing that is required to compile the kernel... It is not anticipated the split I&D restriction will ever be lifted. The historical trend is for systems and programs to increase in size, not decrease. Kernel: - Profiling hasn't been looked at in years. It won't work as it is because the supervisor mode has been allocated to the networking code. - The networking is very stable. The DEQNA, DEUNA, DELUA, Interlan, 3Com, PRONET, ACC LH/DH-11 drivers are known to work; others will require some work. Diffs are provided in /sys/OTHERS for the VAX Excelan EXOS 204 driver. The XNS code is ported, but has to my knowledge never been compiled or tested. The residual PUP support has been removed (as it was in 4.3BSD). SL/IP works but can hang and not restart when you run out of CLISTs. It would probably be a good idea to increase CLISTs to the maximum when running SL/IP. The DEQNA driver is a fresh port from 4.3BSD and is more stable and much less susceptible to hanging than the old version. Don't even THINK of using TRAILERS on *ANY* of the machines in your LAN. In many cases the trailer code has been ifdef'd/commented out from 2.11BSD drivers, in other cases the trailer code has simply been ripped out. In any case, the current drivers drop trailer packets and increment the input packet error count. - The rtp call is wrong, any superuser call to turn off rtp will turn it off, even if it's not the process itself requesting to have its special status revoked. The whole 'rtp' call should probably go away. As far as i know it has never been tested with the present kernel and probably doesn't work. - There should be some way to monitor which overlays you're switching between to aid in determining the best overlay scheme for your kernel. - 2.10.X has not been made to run on the PRO series machines. See sys/OTHERS/PRO for more details and some helpful diffs. The OTHERS directory is quite useful, as it contains many other versions of various drivers and such things. - The directory /sys/vaxif contains the source for the VAX networking drivers. This is an excellent reference for adding new drivers and fixing current ones. Applications: In some of the major source subdirectories you'll see, variously, subdirectories named OLD and PORT. The OLD directories contain old 2.9BSD versions of software which were kept around for porting purposes. The PORT directories contain 4.3BSD code that we didn't have time to port, but felt should be ported eventually. Due to the amount of software ported from 4.3BSD (and the Internet) the number of PORT directories has been cut down in order to fit the distribution on two 1600bpi tapes. Many of the sources not included are available from INTERNET archive sites, others will have to be acquired from a friendly 4.3BSD site. There are only four OLD directories present in the system: /usr/include/OLD, /usr/src/include/OLD (two .h files for support of 'ps'), /sys/pdpstand/OLD (unused standalone programs) and /usr/src/new/OLD where the 2.9BSD remnants are kept. - User level gprof profiling has not been implemented. It should be doable, just hasn't been time to do it. Regular profiling seems to be working fine however. - Lint hasn't been ported yet; the old version is in an unknown state. (it doesn't work) - Ucb/sysline compiles but doesn't run. not a big loss really unless you have a 25 line terminal. - Ucb/systat hasn't been ported. but should be pretty easy EXCEPT for the '-vmstat' display, much of the information there is simply not applicable. - The acucntrl program in the usr.bin/uucp directory doesn't work. It sets flags properly in the kernel, but the tty drivers don't pay any attention to them. See /sys/OTHERS/acucntrl for a fix and comments. The temptation was to simply adopt the 4.3BSD soft-carrier mechanism and modify autoconfig to pass flags to the driver. For now the old method has been left in place. - The PDP-11 lisp hasn't been converted over to the new system calling protocol; it's a fairly straightforward, mechanical process, though. You can find it in /usr/src/new/OLD/lisp11.tar.Z - Most of the applications under /usr/src/new have been tested and work properly. However, a large number of the 4.3BSD new directory remains to be ported ... - Only some of the games have been tested. Most compile, but ... Man pages: The 4.3BSD-tahoe manual page system remains inplace from 2.10.1BSD. Manual page source is generally contained under /usr/src/man. Only preformatted manual pages are stored under /usr/man. The script /usr/man/manroff is used to help format manual pages. Man(1) has been modified accordingly. I'm not happy with this setup, it broke a symmetry i liked, but ... Because the 14 character limit on file name lengths has been lifted there are no manual page files whose names required truncation. The man program will automatically truncate any names over MAXNAMLEN-2, but since MAXNAMLEN is now 63 this should never be a problem unless manual page filename lengths take on the attribute of a novella. The following manual pages are NOT in 2.10BSD but ARE in 4.3BSD: dbx.1 gprof.1 symorder.1 vlp.1 fp.1 liszt.1 systat.1 ad.4 dn.4 kg.4 uda.4 autoconf.4 drum.4 mt.4 up.4 crl.4 ex.4 np.4 ut.4 ct.4 fl.4 pcl.4 uu.4 ddn.4 hdh.4 ps.4 va.4 dmf.4 ik.4 vp.4 dmz.4 ix.4 tu.4 stab.5 config.8 fasthalt.8 restore.8 The following manual pages are NOT in 4.3BSD but ARE in 2.10BSD: mkdep.1 nslookup.1 fetchi.2 gldav.2 nostk.2 rtp.2 fperr.2 lock.2 phys.2 ucall.2 l3tol.3 loadav.3 strcasecmp(3) ldfps.3 ltol3.3 strncasecmp(3) (since block numbers of files are no longer 3 bytes long, the l3tol and ltol3 routines are historical dregs) br.4 ram.4 rp.4 xp.4 dr.4 rk.4 si.4 dvhp.4 rl.4 sri.4 ra.4 rm.4 swap.4 dtab.5 stack.5 tzfile.5 bj.6 ttt.6 warp.6 words.6 moo.6 hostname.7 autoconfig.8 restor.8 The following manual pages DIFFER between 2.10BSD and 4.3BSD: adb.1 f77.1 man.1 px.1 nm.1 pxp.1 as.1 ld.1 pi.1 pxref.1 cc.1 lisp.1 pix.1 make.1 ps.1 adjtime.2 ptrace.2 sigpause.2 write.2 getitimer.2 read.2 sigreturn.2 getrusage.2 setitimer.2 sigsetmask.2 profil.2 sigblock.2 sigvec.2 (differences in the sig* man pages consist of substituting 'long' for 'int') bstring.3 gethostbyname.3 resolver.3 usleep.3 compat-sys5.3 inet.3 setjmp.3 vlimit.3 ctime.3 mktemp.3 signal.3 vtimes.3 execl.3 printf.3 string.3 rand.3 ualarm.3 acc.4 dz.4 inet.4f null.4 arp.4p ec.4 intro.4 pty.4 bk.4 en.4 intro.4n qe.4 cons.4 hk.4 lo.4 rx.4 css.4 hp.4 lp.4 tb.4 de.4 ht.4 mem.4 tm.4 dh.4 hy.4 mtio.4 ts.4 dhu.4 il.4 ns.4f tty.4 dmc.4 imp.4 nsip.4 vv.4 tmscp.4 a.out.5 core.5 dump.5 resolver.5 fs.5 bcd.6 chess.6 mailaddr.7 bad144.8 dump.8 icheck.8 quot.8 badsect.8 dumpdir.8 mkfs.8 reboot.8 clri.8 fastboot.8 named.8 rxformat.8 crash.8 fsck.8 ncheck.8 savecore.8 dcheck.8 halt.8 newfs.8 ======================================================================= The original README file as distributed with 2.10.1BSD ======================================================================= Please see the file /ERRATA for distribution errata notices.

For a detailed explanation of how unsupported this release is, read the kernel changes document. Credit where it's due: Cyrus Rahman, of Duke University, is responsible for much of the work done on various applications for 2.10.1, as well as for making us do select(2) and adjtime(2) correctly. Steven Schultz, of Contel Federal Systems, did the original port of the supervisor space networking, as well as much of the debugging. Keith Bostic {uunet!bostic, [email protected]} Casey Leedom {uunet!ucbvax!vangogh!casey, [email protected]} Cyrus Rahman {[email protected]} Steven Schultz {[email protected]} In general: - The system hasn't been fit onto a non-separate I&D or machine without a floating point processor in a long time. Lots of overlay schemes need to be worked out; the floating point simulator in the kernel hasn't been tested; sendmail won't run on a non-separate machine, so bin/mail and ucb/Mail have to auto-configure not to use sendmail; -DNONSEP needs to be passed up and down the make files (or better yet, the new environment inheritance feature of make should be used to pull out the environment variable MACHDEFS and SEPFLAG); ... The reason this hasn't been done now is, as always, lack of time. Kernel: - Profiling hasn't been looked at in well over a year. It probably doesn't work. - The networking is stable. The DEQNA, DEUNA, DELUA, Interlan and 3Com drivers are known to work; the PRONET and others will require some work. Diffs are provided in /sys/OTHERS for the VAX Excelan EXOS 204 driver. TCP/IP is in place and working; XNS has been ported, but will contain more bugs than the mainstream networking. PUP hasn't even been looked at. SLIP works, but can hang and not restart when you run out of CLISTs. DON'T EVEN THINK OF USING TRAILERS on *ANY* of the machines in your LAN. - The rtp call is wrong, any superuser call to turn off rtp will turn it off, even if it's not the process itself requesting to have its special status revoked. Probably need 3 defines: #define RTP_ON 1 /* turn it on */ #define RTP_OFF 2 /* turn it off if I set it */ #define RTP_FORCE_OFF 3 /* turn off everyone's */ If rtp(2) gets RPT_FORCE_OFF, it should find the process and turn off the stuff, if necessary; question is if rtpp is the flag that everyone checks for the existence of a run-time process. - There should be some way to monitor which overlays you're switching between to aid in determining the best overlay scheme for your kernel. Alternatively, and more correctly, gprof should be implemented for the kernel. - The device number is not currently included in the buffer hashing function, and probably should be. - 2.10 has not been made to run on the PRO series machines. See sys/OTHERS/PRO for more details and some helpful diffs. The OTHERS directory is quite useful, as it contains many other versions of various drivers and such things. - A new directory has been added, /sys/vaxif, which contains the source for the VAX networking drivers. This is an excellent reference for adding new drivers and fixing current ones. Applications: In each of the major source subdirectories you'll see, variously, subdirectories named OLD and PORT. The OLD directories contain old 2.9BSD versions of software which were kept around for porting purposes.

See /sys/OTHERS/acucntrl for a fix and our comments on it. - The PDP-11 lisp hasn't been converted over to the new system calling protocol; it's a fairly straightforward, mechanical process, though. You can find it in new/PORT/lisp11. - Most of the applications under /usr/src/new have been tested and work properly. However, a large number of the 4.3BSD new directory remains to be ported ... - Only some of the games have been tested. Most compile, but ...

The script /usr/man/manroff is used to help format manual pages. Man(1) has been modified accordingly ... Because of the 14 character limit on file name lengths, the names of the following manual pages have been changed: Old name New name -------- -------- getdtablesize(2) getdtabsize(2) getdiskbyname(3) getdiskbynam(3) gethostbyaddr(3) gethostbyadd(3) gethostbyname(3) gethostbynam(3) getprotobyname(3) getprotobyna(3) getprotobynumber(3) getprotobynu(3) getservbyname(3) getservbynam(3) getservbyport(3) getservbypor(3) inet_makeaddr(3) inet_makeadd(3) miscellaneous(7) miscellaneou(7) The man program will automatically truncate any names over MAXNAMLEN-2 (leaving room for the ".x" extension), so this should be transparent (at least until we run into names which aren't unique within the first 12 characters ...
