LIST OF CHANGES FROM LAST RELEASE: <$Revision: 1.913 $> Changes from NetBSD 1.1 to NetBSD 1.2: added support for Win'95 long filenames to msdosfs. [ws 10/11/95] fixed file descriptor leak in ul. [jtc 11/07/95] changed profiling (gmon.c) so that output can be is controlled by the PROFDIR environment variable. [jtc 11/21/95] incorporated diffs to IP networking code for 64-bit cleanliness. [cgd 11/21/95] changed definition of profil() to be 64-bit friendly. (This has no real effect on 32-bit systems.) [cgd 11/22/95] changed send-pr to handle '&' expansion of user name from password database. [jtc 11/22/95] added spanish language libc message catalog contributed by Jesus M. Gonzalez . [jtc 11/22/95] hp300: made COMPAT_HPUX partially work. This is a checkpoint/snapshot, done with the intent that others will be able to track the code more easily. Several HP-UX 9.x executables tested work "OK". Much more work yet to be done. [thorpej 11/28/95] atari: added support for a separate {prof,stat}clock [leo 12/01/95] atari: now using more functional fpe support [leo 12/01/95] hp300: use "match/attach" rather than "init" routines for probing devices. This is one of the many steps towards using new config. [thorpej 12/02/95] hp300: Added Swedish HIL keymap, submitted by Tomas Tengling . [thorpej 12/06/95] Imported gcc-2.7.2 into src/gnu/sur.bin/gcc. [phil 12/1/95] renamed uuencode.format(5) to uuencode(5). [jtc 12/04/95] integrated version 9.11.5 of termcap database. [jtc 12/04/95] Changed sys/scsi/sd.c and sys/scsi/cd.c to use a 6-byte read/write cdb if the transfer request will fit, and the 10-byte cdb otherwise. In sdattach(), note if the device is "ancient". Implement sdminphys() which shortens the transfer to fit in a 6-byte cdb on "ancient" devices. Fixes problems with rejected commands on many Emulex ESDI->SCSI bridges. [thorpej 12/07/95] Moved the m68k bcopy, ovbcopy, and memcpy functions out of each port's locore.s and centralized them in m68/m68k/copy.s. [thorpej 12/10/95] hp300: some cleanup in locore.s and others. Changes are geared towards finding common ground between the m68k ports and pulling them out into . [thorpej 12/11/95] Added -Werror to bsd.sys.mk, so programs which use the NetBSD build environment build with -Werror. [cgd 12/12/95] vax: Added support for MicroVAX III (VAX 3600/3800/3900). Walk slowly towards using new config everywhere. changed NFS code to work on 64-bit systems. (Really just changed the code so that structures, etc., used in implementing the wire protocol used fixed-size types.) [cgd 12/19/95] started a collection of machine-independent TurboChannel code, to be shared between the pmax and alpha ports. [cgd 12/19/95] fixed strftime's %u format to expand to a single digit. [jtc 12/28/95] applied groff portion of diff in pr#1859. This diff updated for loops to conform to the newer ANSI scoping rules. [chopps 12/29/95] added $mrouted_flags to /etc/netstart and use them in /etc/rc to start mrouted like $routed_flags are used to start routed. [thorpej 12/29/95] added a vnd(4) manual page. [thorpej 12/30/95] fixed libg++ to compile with newer gcc. closed pr#1859 [chopps 12/30/95] added David Jones' new MI NCR5380 driver to sys/dev/ic. [thorpej 01/01/96] sparc: added my port of the sun3 `ncr_si' driver plus my additions to support the 4/100 `sw' controller. Uses MI NCR5380 code. [thorpej 01/01/96] fixed identd userid format to conform to RFC1413. Patch from der Mouse in pr#1848 [jtc 01/02/96] vax: Added support for TS11/TSV05 tape drives. Device driver written by Bertram Barth, based on TMSCP code. [ragge 01/06/96] atari: Added nvram driver. [leo 01/06/96] upgraded zoneinfo code to tzcode96a. [jtc 960108] upgraded zoneinfo data to tzdata96a. [jtc 960108] New generic disk framework. Highlights: - New metrics handling. Metrics are now kept in the new `struct disk'. Busy time is now stored as a timeval, and transfer count in bytes. - Storage for disklabels is now dynamically allocated, so that the size of the disk structure is not machine-dependent. - Several new functions for attaching and detaching disks, and handling metrics calculation. Old-style instrumentation is still supported in drivers that did it before. However, old-style instrumentation is being deprecated, and will go away once the userland utilities are updated for the new framework. For usage and architectural details, see the disk(9) manual page. [thorpej 01/07/96] Added copy(9), fetch(9), and store(9) manual pages, based on a suggestion from Kenneth Stailey. [thorpej 01/08/96] Add support for the SMC8416 (EtherEZ) ISA ethernet card. (imported from OpenBSD/FreeBSD) [chuck 01/10/96] Added erase and cache request to MI SCSI tape driver, from John Kohl. [thorpej 01/10/96] isa: added "ahe" driver, autoconfiguration support for ISA/VLB/EISA aic7xxx-based SCSI controllers from Michael Graff. [01/12/96 thorpej] sys/lib/libsa: Splitted some sources files containing more than one function. Allowing for a possible decrease of the bootloader size. closes pr#1817. [leo 01/13/96] m4: handle multi-character quote and comment delimiters Patch forwarded to Ozan Yigit [pk 01/13/96] sparc: added "mountroot hook" for dealing with a device's special needs before (*mountroot)() is called. Make the floppy driver register a mountroot hook used to eject the floppy and prompt user for filesystem floppy if it's the root device. Add better disklabel handling to floppy driver. [thorpej 01/14/96] netinet: added net.inet.ip.forwsrcrt sysctl. If zero, the system will not forward source-routed packets. The name is consistent with the BSD/OS sysctl that does the same thing. [thorpej 01/15/96] netinet: added net.inet.ip.directed-broadcast sysctl, slightly modified from a patch submitted by Darren Reed. [thorpej 01/15/96] msdosfs: Removed '#ifdef atari's. Make mounting the Atari-Gemdos flavour of msdosfs an option passed by mount. [leo 01/19/96] upgraded more(1) to less version 290. note that this also installs as /usr/bin/less now. [mrg 960122] upgraded sendmail to version 8.7.3. [mrg 960122] redesigned z8530 serial driver to make it attach child devices for keyboard, mouse, or plain tty. [gwr 960123] Move disk-specific ioctls from to which is implicitly included by . Define and implement DIOCLOCK, which is used to lock/unlock a disk pack. Teach several drivers and the eject(1) program about the new interface. SCSI disk driver now has ability to eject removable media with software. CD-ROM drivers maintain compatibility with the old CD-ROM lock/unlock/eject interface. [thorpej 01/30/96] cmp -s no longer complains about missing filess. [mrg 960201] changed names of timespec struct's fields from ts_* to tv_* to conform to POSIX.1b. [jtc 960201] changed quota and rpc.rquotad to use ffs instead of ufs. [jtc 960201] ccd: add experimental data mirroring support, mostly from Satoshi Asami and Nisha Talagala, with some changes by me. [thorpej 02/01/96] added -s flag to syslogd -- this makes syslogd open only the unix domain socket and not the network, which is important on firewalls and other machines which could be attacked over the network. [perry 960204] mac68k: New, calibrated delay() implementation. [briggs 960203] to be any of the first 32 instead of first 8. [briggs 960211] dump(8) and restore(8) now support $TAPE as the default device. [mrg 960206] vax: Massbus adapter support and Massbus disk support added. (RP04/05/06/07 disks). [ragge 960211] mac68k: Changed partition strategy a bit to allow boot partition to be any of the first 32 instead of first 8. [briggs 960211] hp300: New, better interrupt handling code. Eliminates most hard-coded driver references in locore.s. [thorpej 02/13/96] audio: New ioctl AUDIO_PERROR (playback error count); new mode flag AUDIO_PLAY_ALL to indicate that all samples should be played rather than time correcting with silence. [jtk, 02/16/96] Rick Macklems's NFSv3 code from Lite2 brought in [fvdl 021896] Virtual 8086 mode kernel support, library support added to i386 port [mycroft & jtk, 960222] hp300: New console probing code. [thorpej 02/23/96] telnet: updated to telnet-95.10.23 version. src/domestic has the full version with encryption. [jtk, 960224] added better EISA bus autoconfiguration support. Mostly taken from PR 1959. [cgd 960226] Replace config_found() with config_found_sm(), which adds a cfmatch_t to the argument list. This allows easy 'submatching', which will eliminate a fair bit of slightly tricky duplicated code from various busses. config_found() is now a #define in sys/device.h, which invokes config_found_sm(). [cgd 960227] sparc: add support for P4 framebuffers [thorpej 02/27/96] updated sendmail to 8.7.4. [mrg 960228] made ISA and PCI autoconfiguration (match, attach, attachment of subdevices) machine-independent. [cgd 960227] added preliminary support for PCI-PCI bridges. [cgd 960227] sun3: added PMAP_PREFER for performance boost on the Sun3/260 machines. [gwr 960228] atari: The Atari-port now has a NetBSD-bootloader that can be installed in a bootblock. It is now possible to boot into NetBSD directly. [leo 960228] vax: Support for VAX 11/780 - 11/785 added. Device driver for DHU11 serial card, written by Ken Wellsch, added. [ragge 960302] i386: changed autoconfiguration so that isa, eisa, and pci busses attach to mainbus which attaches to root, rather than attaching root directly. [cgd 960303] added _MACHINE and _MACHINE_ARCH to each port's include/param.h. They're like MACHINE and MACHINE_ARCH, but without the quotes. [cgd 960303] scsi: normalized SCSI autoconfiguration messages. [thorpej 03/04/96] i386: added EXTMEM_SIZE kernel option so that people who own machines that lie about the size of extended memory can use the hardware they paid for. [thorpej 03/04/96] amiga: added console driver for the CyberVision64. [veego 960302] mt(1) supports access of remote tapes via rmt(8). [scottr 960305] vax: Support for VAX 8600/8650 cpu types added. [ragge 960307] added a set of interfaces, which live in , which define standard, machine-independent ways to map and access device I/O and memory spaces. [cgd 960308] i386: changed faked-up disklabel to include BIOS partitions in order to allow people to mount DOS partitions on disks with no NetBSD partition. [ghudson 960309] i386/isa: reworked multi-port board interface with 'com' driver so that (among other things), 'flags 1' is no longer necessary for 'com' ports attached to the 'ast' multiport board. Removed understanding of 'flags 1' from com.c. [cgd 960310] pc532: reported pmap.c, removed double mapping, improved copyin copyout, etc. [phil 960214] pc532: moved port to use MI ncr5380 driver. [phil 960311] gnu: imported libg++-2.7.1 [phil 960309] Added the total number of sectors to disklabel's text representation of a label, since calculating based on the geometry isn't always accurate. [ghudson 960314] atari: now uses the MI ramdisk driver. [leo 960314] finished prototyping the mi portion of the kernel. Things to do is fix the _conf.h crud and cleanup the printf() debugging calls. [christos 960314] renamed fdopen() to filedescopen() so that it does not collide with the fdopen() in the floppy driver. [christos 960314] sparc: Prototyped the md portion. The whole sparc kernel compiles cleanly now. [christos 960314] i386: change pms driver to be a child of the "keyboard controller" rather than isa. [thorpej 960315] i386/isa: add MediaVision Jazz16 support for sb driver (jtk) New device attachment scheme. - split softc size and match/attach out from cfdriver into a new struct cfattach. - new "attach" directive for files.*. May specify the name of the cfattach structure, so that devices may be easily attached to parents with different autoconfiguration semantics. Changes to config(8) and kern/subr_autoconf.c from Chris Demetriou . [thorpej 960316] New libkvm/savecore. 1) savecore will not access the dump or live-kernel directly. It will always use the kvm-functions. Allowing it to work on kernels that don't have a 1-1 PA-VA mapping. 2) the kvm-lib has some additional functions to accomplish 1 - kvm_dump_mkheader() - kvm_dump_wrtheader() - kvm_dump_inval() 3) the file formats of the dump generated by the kernel and the dump generated by savecore have been changed. The file format now looks like the format produced for 'normal' core dumps. Ports not yet supporting the new kvm-format will be using libkvm.old/savecore.old for the time being. [leo 960317] config: Add BSDI-style expression support to optional file specifiers. Code mostly taken from the parts of BSDI's 'config' which are freely-distributable (under the LBL/UC Regents license), and adjusted to fit into our version. Instead of simple option lists used to include optional files, you can now use parentheses, &, |, and !. [cgd 960317] telnet: Fix domestic/usr.bin/telnet to use the true host name when IP numvers or CNAMEs are used. [explorer 960322] sys/dev: Convert the ramdisk to a pseudo-device [gwr 960322] sun3: Reworked the autoconfiguration design to allow control over the order of attachment calls on mainbus and obio. This should allow the eventual removal of several hacks to get some devices configured before autoconfig. Also, adapted to (and took advantage of) the new attachment interface by "carving up" the "ie" and "si" drivers. Added drivers for the interrupt register (intreg) and the memory error register (memerr). [gwr 960326] sys/dev/pci: changed the interfaces used by PCI device drivers, to allow more flexibility for the implementation and to make them more portable to 'weird' architectures. Documented to current-users, and will be documented eventually in section 9 manual pages. [cgd 960326] atari: Added centronics printer driver [leo 960327] amiga: Added Emplant SCSI driver by Sean Riddle and Bo Najdrovsky [is 960328] move 'savecore.old' functionality and build back into 'savecore' since most of it was redundant, and to simplify the build process. [cgd 960330] remove redundant 'libkvm.old' files, and fetch them by .PATH from libkvm. [cgd 960401] scsi: Added bew SCSI changer driver and userland controller utility. [thorpej 960402] change 'alldevs' and 'allevents' lists to be TAILQs, rather than home-grown lists. [cgd 960403] change config_found(), config_rootfound(), and config_attach() to return the 'struct device *' of the newly attached device rather than an int (for the former two) or void (for the latter). Change several drivers to take advantage of this, to remove hackish open-coded variants of config_found(). [cgd 960404] added Ian Dall's ieee fp support to pc532 port. [phil 960404] Applied PR 2006 (from me, with some fixes) to rename 'fsck' to 'fsck_ffs', so that in the future 'fsck' can be used as a wrapper to call the correct file system checker. For now, fsck is link to fsck_ffs. [cgd 960404] vax: Added DZ11 serial line drivers. Written by Ken Wellsch. [ragge 960408] sys/dev/eisa: changed the interrupt attachment/detachment interfaces used by EISA device drivers, to allow more flexibility for implementations, to allow interrupt information to be printed more easily, and to remove the direct dependence on the ISA interfaces. [cgd 960409] fixed old fdesc's /dev/tty bug is a named pipe. [mrg 960411] sys/dev/isa, and i386 ISA code: changed interrupt attachment/detachment interfaces to take a machine-dependent-code-supplied cookie, to allow implementations more flexibility when writing these functions. [cgd 960411] amiga: - Many -Wall and -Wstrict-prototypes fixes. - updated CyberVision64 driver, from Michael Teske. - fixed a mbuf problme in the ariadne driver, from Michael L. Hitch and Michael van Elst. - ite no longer forgets keymap on reinit, from teske@mail.desy.de (Michael Teske). [veego 960422] amiga: changed the speed calculations of the builtin serial driver to allow any baudrate the hardware allows, and to forbid two baudrates (50 and 75) which the hardware does NOT support but which the old speed conversion table pretended to support. [is 960423] amiga: made the mainboard mice real devices instead of pseudo-devices. [is 960424] ep driver: split up driver into eisa, isa, and pci front ends, and a bus-independent core driver, taking advantage of the cfattach autoconfiguration code. Driver still needs to be converted to use . [thorpej 960424] pcnfsd: Correct vulnerabilities noted in CERT advisory CA-96.08 [gwr 960424] mvme68k: add scsi driver, new autoconfig/interrupt scheme, new delay(), new disklabel code, switch to MI zs driver. [chuck 960426] sys/sys/socket.h: added #ifndefs to enable options SOMAXCONN=n [neil 960502] updated the version of Berkeley DB in libc to DB 1.85 [cgd 960503] sun3: Implemented kernel crash dumps [gwr 960505] usr.bin/file/magdir: added os9 (OS9 + OS9/68K module patterns) [is 960506] dev/isa: added first version of iy driver (for Intel Etherexpress PRO). Should work for any i82595 ISA board with EEPROM; NETBLK is not supported yet. No multicast support yet. [is 960505] changed struct ifnet to have a pointer to the softc of the underlying device and a printable "external name" (name + unit number), thus eliminating if_name and if_unit. Updated interface to (*if_watchdog)() and (*if_reset)() to take a struct ifnet *, rather than a unit number. [thorpej 960506] LANCE: made the MI LANCE driver standalone, using cfattach to resolve naming conflicts on ports which can have more than one instance of the LANCE. [thorpej 960506] imported x68k port for SHARP X680x0 computer. [oki 960505] sparc: support for sun4m class machines (Classic, LX, SS10, SS20). [pk 960506] changed ECOFF structure members to have their 'normal' names, not names that were picked apparently at random. [cgd 960509] amiga: added DraCo and M68060 support [is 960509] updated systat(1), vmstat(8), and iostat(8) to display disk statistics kept by the NetBSD generic disk framework, from John M. Vinopal . [thorpej 960510] changed message catalog system to use a more efficient machine independent file format. [jtc 960514] add fsck_msdos, a filesystem checker for msdosfs [ws 960514] added getmaxpartitions() and getrawpartition() functions to libutil, and updated appropriate utilities. [thorpej 960515] m68k: imported M68060 software package by Motorola, and added some glue code [is 960516] x68k: imported method of distribution. [oki 960517] hp300: properly calibrate the kernel delay() function. [thorpej 960518] sendmail: upgraded to version 8.7.5. [mrg 960518] amiga: - updated grfcl to support the Piccolo SD64. - added a blank ioctl for the RetinaZ2/Z3. - new graphics driver (grf6) for the oMniBus, Domnio and Merlin, from tabt@studbox.uni-stuttgart.de (Tobias Abt) [veego 960518] Removed GCC 2.4.5 (src/gnu/usr.bin/gcc2) from the source tree, since it's no longer used by any architectures. [cgd 960519] atari: added edahdi, a simple editor to modify partition id's on an AHDI labeled disk [leo 960519] atari: added a miniroot distribution. It is basically the same as the MI-miniroot but because I have only 1Mb to play with, some of the tools (awk,cut,grep,..) didn't fit and the scripts have been rewritten to deal with this. Also added an option to install from a 'normal' (== hd/mo/...) disk partition to allow people to gather the sets using the native OS and mount that parition from the installer. XXX: All of the above changes can (and should) be merged XXX: into the MI-miniroot. [leo 960519] add the if_strip.driver by Jonathan Stone and Stuart Cheshire for the Metricom Ricochet radio [jonathan 960519] update support for the DEC PDQ-based FDDI controllers, including new support for EISA and TurboChannel variants, from Matt Thomas . [thorpej 960519] make tcpdump understand NFSv3 and NFS over TCP [fvdl 960519] mac68k: Change framebuffer configuration to layer grf semantics onto separately attached hardware; this allows greater flexibility in video configuration. [scottr 960519] vi: updated to nvi 1.66 (from Keith Bostic). [mrg 960520] amiga: added support for screenblank program [is 960521] mvme68k: new standalone code [chuck 960528] Changes from NetBSD 1.2: Removed locc() from the supported set of machine-independent kernel kernel functions, since it's unused. [cgd 960610] mac68k: rewrite setroot() and friends to allow more flexible root/swap device configuration (including NFS). [scottr 960619] Add support for ATM networks and efficient networks ATM pci and sbus atm cards [chuck 960621] Added my extent map manager; kern/subr_extent.c, sys/extent.h. [thorpej 960622] i386: implement i/o port accounting in bus_io_{,un}map(). [thorpej 960623] hp300: re-vamp boot code. Now, a single unified boot block (SYS_UBOOT) supports booting from SCSI and HP-IB disk and network. Infrastructure for booting from HP-IB tapes is there, but doesn't quite work yet. [thorpej 960626] sparc: added driver for the TCX framebuffer [pk 960626] Add native mode ATM protocol layer (aal0 & aal5) [chuck 960703] Update aic7xxx and the aic driver from FreeBSD, care of pr port-i386/2600 and Noriyuki Soda [explorer 960711] Increase FD_SETSIZE from 256 to 2048; the kernel already allows more than this. [explorer 960716] Add compile-time control of autonice time and autonice value using "options AUTONICETIME=sec" and "options AUTONICEVAL=6" in kernel config files. Also, sysctl can be used to tweak these in a running system. See man {3,8} sysctl for more information. [explorer 960717] vax: Added support for: VAX 8200/8250/8300/8350 VAXBI based machines, and KDB50 disk controller. VAXstation 2000/MicroVAX 2000, together with ST506 and SCSI disks and LANCE ethernet. VAXstation 3100/76 with some SCSI support. [ragge 960720] Add AHA-284x VL frontend to ahc driver written by Jason Thorpe. [soda 960805] mac68k: attach the ite to the appropriate grf device, as determined by the booter. [scottr 960805] Slight semantics change to passwd(1) and chpass(1): ALWAYS use YP if the system is bound to a YP server. This is required if the passwd database is to stay in sync if this program is run on the YP server. Note, local passwd database operations can still be performed by passing the -l flag. [thorpej 960809] Added the ypserv suite written by Mats O Jansson, with some changes by me. Changed the way YP daemons are started in /etc/rc. [thorpej 960809] Changed the reboot(2) system call to take (int bootopt, char * bootstr) to allow smarter firmwire the ability to reboot with a string. [mrg 960809] Imported Vernon Schryver's new routed(8) implementation, which understands RIPv1, RIPv2, and ICMP Router Discovery. [thorpej 960809] Fixed disklabel not to display cylinder comments if number of sectors per cylinder is zero. From pr bin/2683. Also deal with syntax errors in a more sane matter. From pr bin/2659. [explorer 960810] Fixed lpr to do less things as root. Fixes pr bin/2597. [explorer 960810] Fixed pppd to not try to delete its pid file if it never created it. Fixes bin/2388 and bin/2551. [explorer 960810] Add ppp(4) and sl(4) man pages. Closes pr bin/2481, kern/2493, and kern/2494. [explorer 960810] Replaced fingerd with an updated one from OpenBSD. This closes some denial of service attacks and adds new features. Fixes pr bin/2456. [explorer 960810] Add panic(9) man page. Fixed pr misc/1342. [explorer 960810] Fix tty baud rate passing in rlogin.c. Closes pr bin/2684. [explorer 960810] Add some very basic lkm stuff to sys/lkm. [explorer 960822] atari: 68040 pmap stuff now works [leo 960823] atari: Don't map the st-io area on a fixed address, let atari_init.c decide the best place. [leo 960823] atari: First steps done for the Hades-port. It boots but has no console or disk devices. [leo 960823] i386: added advanced power management driver. [jtk 960825] Add machine-independent assertion-checking macros (assert, KASSERT, KDASSERT). [cgd 960826] Implement kernel realloc(), just like the user-land version, except it takes "type" and "flags" arguments a la kernel malloc(). [cgd 960827] Change cfprint_t to take a const char *, rather than a char *, since the parent name must not be modified. [cgd 960827] Add IP multicast to ARCnet broadcast mapping, as per RFC 1122, section 3.3.7. [is 960902] netinet: Added pfil (packet filter) interface, to allow any packet filter to work without kernel modifications. needs options PFIL_HOOKS. [mrg 960905] kern: added getpgid(2) system call, as per SVR4. [mrg 960905] kern: changed reboot(2) system call to take a string of boot commands, to be handled by the machine dependant boot() function. current only the sparc and sun3 ports use this.
