What's new since 3.0-RELEASE --------------------------------- All changes described here are unique to the 3.0 branch unless specifically marked as [MERGED] features. 1.1. KERNEL CHANGES ------------------- -o The 2.2.x SCSI subsystem has been almost entirely replaced with - a new "CAM" (Common Access Method) SCSI system which offers - improved performance, better error recovery and support for more - SCSI controllers. - -o The Host ATM Research Platform ("HARP") software by Network - Computing Services, Inc. has been integrated into the system. - See /usr/src/share/examples/atm for more info. - -o The SMP (Symmetric MultiProcessing) branch has been merged. - The kernel is mostly non-reentrant as yet, but work is under way. - -o The code from 4.4BSD-Lite2 has been (finally) merged. - -o Secure RPC is now supported (and usable with NFS et al). - -o Sun's WEBNFS standard is now supported. - -o The MSDOS filesystem code now handles VFAT and FAT32 partitions. - [MERGED: Also in 2.2.7 and later releases on 2.2-STABLE branch] - -o ATAPI/IDE CD burner support (BETA). - -o ATAPI/IDE tape drive support (BETA). - -o Support for using VESA video modes. It is now possible to select and - use the modes provided by the BIOS on modern videocards. This enables - fx. 132x60 sized consoles and highres graphics in a generic manner on - hardware that supports it. There is also support for running the - console in rastermode, which allows XFree86 to run a simple 16color - server in 800x600 on otherwise unsupported video hardware. - -o Support for AdvanSys SCSI controllers - -o Support for QLogic SCSI and Fibre Channel controllers. - -o Support for Adaptec 7890, 7891, 7895, 7896 and 7897 based controllers - (new 2940/2950/3940/3950 et al). - -o The ed0 (wd8xxxx, 3c503, NE2000, HP Lan+) Ethernet device's default IRQ - has changed from IRQ 5 to IRQ 10. - The ed1 Ethernet device has been removed. Use the Userconfig utility - to change ed0's values to match your network card's settings. - [MERGED: Both changes are in 2.2.6 and later releases on 2.2-STABLE branch] - -o The code responsible for maintaining time of day has been - rewritten. New features are: true support for nanoseconds in - both kernel and userland, continuous rather than stepwise adjustment - by NTPD and support for synchronizing to high precision external time - signals. - -o Support for the PPS API described in draft-mogul-pps-api-02.txt for - TTL rising edge inputs via the parallel printer port has been added - to the printer driver. - -o Use the new if_multiaddrs list for multicast addresses rather than the - previous hackery involving struct in_ifaddr and arpcom. Get rid of the - abominable multi_kludge. - -o The new if_media selection method for ethernet drivers has been brought - in, obtained from Jason Thorpe's implementation for NetBSD. - [MERGED: Also in 2.2.5 and later releases on 2.2-STABLE branch] - -o Multi-session ISO-9660 CD-ROMs are now fully supported. By default, the - last session will be mounted (including for root mounts). For non-root - mounts, mount_cd9660(8) can take an argument to mount a particular - session instead of the default one. - -o The UPAGES are gone from the per-process address space which allows - complete address space and page table sharing by reference count. - -o Newly forked child processes return directly to user mode rather than - return up through the fork() syscall tree. This eliminates the kernel - stack copy at fork time and simplifies certain other internal operations. - It is also needed to support the removal of the UPAGES. (The idea for - this originally came from NetBSD, but we did it for different reasons.) - -o vfork() is now fully functional by taking advantage of the new sharing - semantics and a significant speedup has been measured. This can be - disabled via the kern.fast_vfork sysctl variable in case of problems. - Statically linked binaries from older releases and other BSD platforms - are a problem since there was a bug in the 4.4BSD (net2, Lite and Lite2) - popen() implementation. rfork() also has access to these facilities, - intended for supporting kernel assisted threads. - -o With the contribution of Berkeley Software Design, Inc., Jonathan Lemmon, - Mike Smith, Sean Eric Fagan, and John Dyson, VM86 support has been added - to the kernel, and BSD/OS's contributed dosemu has been ported. - -o The SA_NOCLDWAIT flags has been implemented, featuring the System V - option where a process can express its wish to never get zombies or - SIGCHLD for dead children. - -o An implementation of poll(2) is in place, the core of which is derived - from the NetBSD implementation. Both the select() and poll() syscalls - use the poll device, file and vnode ops routines. - -o An implementation of issetugid(2) that is similar to the OpenBSD call - of the same name. We set the flag in more cases than OpenBSD - our - implementation is slightly more paranoid. - -o Async IO is implemented (under non-SMP at this stage) with additional - support for kernel assisted threads. - -o Some other misc syscalls for compatability with other systems: getsid(2), - setpgid(2), nanosleep(2). - -o A new syscall signanosleep(2) which is like nanosleep(2), but a specific - signal mask is used to determine which signals will wake the sleep. In - a nutshell this is 'wait for a given set of signals for up to a certain - amount of time'. - -o sleep(3) and usleep(3) are now implemented in terms of signanosleep(2) - and now have correct SIGALRM interaction semantics and sleep(3) correctly - returns the time remaining. Some programs (notably apache httpd) bogusly - depend on a sleep() "absorbing" a SIGALRM from a timer that expires during - the life of the sleep. - -o An in-kernel linker is implemented and intended to replace the lkm system - with the bogosity that goes with it. - -o All supported network protocols have been updated to avoid the ``big - switch'' pr_usrreq(), and to pass a process pointer down to each user - request that might need process credentials or want to sleep, - replacing the previous hodgepodge of inspecting curproc (which only - occasionally did the right thing) and the SS_PRIV socket state flag. - The latter has now been eliminated, along with the SO_PRIVSTATE socket - option which cleared it. Protocols are now also given the opportunity - to override the generic send, receive, and poll routines, which will - make it possible for a more efficient, protocol-specific - implementation of these entry points in later releases. Finally, many - parts of the network code have been modified to cease storing socket - addresses and other metainformation in mbufs, in preparation for the - eventual elimination thereof. The mechanism by which socket addresses - are now returned is still highly subject to change as we experiment to - discover the most efficient method. - -o Responses to multicast ICMP ECHO REQUEST (``ping'') and ADDRESS MASK - REQUEST packets can now be disabled via sysctl. The netstat program - will print out statistics on how many times this happens. - -o A subtle and seldom encountered bug in ffs has been fixed. - -o The VFS name cache has been reworked to be more accountable and efficient. - -o The generic part of VOP_LOOKUP() has been put it in system-wide function - which filesystems can rely on for the canonical stuff. - -o Vnode freelist handling has been hauled over. Vnodes are only on the - freelist if nobody cares about them. - -o The kernel provides assistance to getcwd() from data stored in the name - cache if possible. - -o An interrupt driven configuration hook mechanism has been implemented. - This allows drivers to postpone part of their configuration until after - interrupts are fully enabled. This speeds booting because busy-waiting - is avoided for things like sub device probing (eg: SCSI bus probes). - -o The timeout(9) system in the kernel has been overhauled. This gives - O(1) insertion and removal of callouts and an O(hash chain length) - amount of work to be performed in softclock. The original paper is at: - http://www.cs.berkeley.edu/~amc/research/timer/ - -o Changes in driver buffer queuing to deal with ordered transactions. This - is intended for sequencing data and metadata writes in the filesystem code - once fully supported. - -o EISA Shared interrupts are now supported, working with the framework - originally for supporting PCI shared interrupts. - -o Support for the Comtrol Rocketport card. - -o IPFW's packet and byte counters have been expanded from 32 to 64 bits, - a `FWD' operation has been added to ipfw to support transparent - proxying and the divert operation has changed slightly - see the man - pages for natd(8) and ipfw(8) for more information. - -o New Plug and Play (PnP) support that allows you to (re)configure PnP - devices. Also support modems being detected by the PnP part and - automatically attached. - [MERGED: Also in 2.2.6 and later releases on 2.2-STABLE branch] - -o Import of new sound code from Luigi Rizzo. This code is still being - developed, but has support for a number of different cards. - [MERGED: Also in 2.2.6 and later releases on 2.2-STABLE branch] - -o The psm, mse and sysmouse drivers are improved to provide better mouse - support. In particular, the psm driver now supports various ``wheeled'' - mice. - [MERGED: Also in 2.2.6 and later releases on 2.2-STABLE branch] - -o Added support for SMC EtherPower II 10/100 Fast Ethernet card - (aka SMC9432TX based on SMC83c170 EPIC chip). - [MERGED: Also in 2.2.7 and later releases on 2.2-STABLE branch] - -o Added support for ATAPI floppy drives (LS-120). - [MERGED: Also in 2.2.7 and later releases on 2.2-STABLE branch] - -o Added support for IBM Etherjet and other Crystal Semiconductor - CS89x0-based NICs. - [MERGED: Also in 2.2.7 and later releases on 2.2-STABLE branch] - -o Added support for Texas Instruments TNET100 'ThunderLAN' PCI NIC. - [MERGED: Also in 2.2.8 and later releases on 2.2-STABLE branch] - -o Added full bus master DMA support for 3c900 and 3c905 adapters and - added support for the 3c905B. - [MERGED: Also in 2.2.8 and later releases on 2.2-STABLE branch] - 1.2. SECURITY FIXES ------------------- -[MERGED: all changes soon after specified date in 2.2-STABLE branch] - -97/7/29 Lots of lpr/lpd security fixes merged from OpenBSD. -97/8/22 buffer overflows in tip corrected (benign since tip isn't - set[ug]id) -97/8/26 buffer overflow in glob fixed, no know exploits -97/8/27 vacation security problem with sendmail corrected (SNI) -97/8/29 inetd sleeps less when children exit, making DoS attacks much - harder. -97/8/29 fts now race-proof and find -execdir added (-current only) -97/8/31 games setuid -> setgid. Makes any games exploits benign (only - score files vulnerable). Please report any problems to - eivind@FreeBSD.org (score-file ownership problems are known) -97/12/3 Add Intel's suggested fix for the F00F bug. If you don't have - a Pentium, the NO_F00F_HACK kernel option will disable it. -98/1/20 More robust protection against LAND attacks now incorporated. - -The suidperl vulnerability mentioned in the CERT advisory CA-97.17 is -also believed to be fixed. - -KerberosIV is now merged. - 1.3. USERLAND CHANGES --------------------- -The default binary type (and compiler toolchain) has been -switched from a.out to ELF. This gives us access to much -newer compiler technology (much of which didn't support a.out), -allows for smaller executables and provides much better -support for languages like C++, among many other advantages. -Older a.out libraries and binaries will, of course, continue to work -and provisions have been made for having both varieties installed if -and as necessary for transitional purposes. - -Perl4 has now been replaced by Perl5 as a standard part of the -system. - -The default username length has increased to 16 characters. -Caution: Old utmp/wtmp files will NOT work with this change since -the data records will be of the old size. For a conversion utility -to aid with this, see /usr/src/tools/3.0-upgrade. - -/etc/sysconfig now replaced by more compact /etc/rc.conf file -[MERGED: Also in 2.2.1 and later releases on 2.2-STABLE branch] - -fdisk(8) now numbers disk slices from 1 to 4 rather than from 0 to 3. -This brings it in line with the numbers used in the device names -in /dev. - -The Amd automounter has been updated from the 1993 4.4BSD version to -the latest current version of am-utils. Map options have changed -somewhat, and a new configuration file, /etc/amd.conf, is supported. -See ``man 5 amd.conf''. - -The ``picobsd'' package for creating custom FreeBSD boot floppies -and "mini systems" has been brought into /usr/src/release/picobsd. -See file:/usr/src/release/picobsd/README.html for further information. - -When operating over the network, finger(1) no longer closes the socket -immediately after sending its request, but instead waits for the -remote end to close first. (The specification is ambiguous, so we are -following the behavior which interoperates with the most servers.) -This means that it is now possible to use the MIT directory and finger -people at certain broken Linux machines. - -There is a new flag to fetch(1) which allows it to talk to certain -broken HTTP implementations which react badly to a request message -immediately followed by a close of the connection. - -netstat(1) now uses sysctl(3) to retrieve more statistics groups and -uses the correct, unsigned format for printing most of them out. - -A new VGA library (/usr/src/lib/libvgl) now exists for doing simple -VGA graphics to syscons ttys (sort of like Linux's libSVGA). -[MERGED: Also in 2.2.5 and later releases on 2.2-STABLE branch] - -Xntpd's syslogging has been moved out into a facility of its own -(LOG_NTP, userland name "ntp"). - -A new pair of ioctl's has been added: SIOC[SG]IFGENERIC. The intent -is to provide for a hook to pass arbitrary ioctl subcommands down to a -network interface driver. This is for example necesseray for PPP -drivers to communicate things like CHAP names and secrets, or variable -options between the driver and a userland utility. - -sppp(4) has been improved a fair bit since FreeBSD 2.2.X. It now -employs a full-fledged PPP state machine, offers a lot more of LCP and -IPCP negotiation, making it ready for dial-on-demand connections (like -those that are often running over ISDN). It also offers PAP or CHAP -authentication. The userland counterpart spppcontrol(8) is also the -first program that utilizes the abovementioned SIOC[SG]IFGENERIC ioctl -commands. - -moused(8) has been modified to support various mice with a ``wheel''. -It also automatically recognizes mice which support the PnP COM device -standard, so that the user is no longer required to supply a mouse -protocol type on the command line. -[MERGED: Also in 2.2.6 and later releases on 2.2-STABLE branch] - -ppp(8) supports many additional features including the PPP Multilink -Protocol (rfc1990), PPP Callback (with CBCP extensions) and client -side DNS negotiation. Refer to the README.changes file in the source -directory for details of possible configuration conflicts. - -Pthread read/write locks as defined by the Single UNIX Specification, -Version 2, have been added to the POSIX threads library, libc_r. - -System files are now owned by user `root', group `wheel'. UID 0 is far -more protected than `bin'. Especially over NFS. - -/bin/sh signal and trap handling reworked. Among other things, this -makes tty-mode emacs work when called from system(2), i.e. by a mail -agent. Several syntax bugs have been fixed. -[MERGED: Also in 2.2.8 and later releases on 2.2-STABLE branch] - -systat(1), iostat(8), rpc.rstatd(8), and vmstat(8) have been -overhauled to use the new devstat(3) library and devstat(9) statistics -subsystem. Among other enhancements, these utilities (well, with the -exception of rpc.rstatd(8)) now print out more useful statistics, and can -see statistics for all devices in the system, not just the first 8. 2.
