Changes from NetBSD 1.3 to NetBSD 1.3.1
NetBSD 1.3.1 was released on March 9, 1998, fixing bugs and adding some new
hardware support to NetBSD 1.3. It can be installed following exactly
the same procedure as NetBSD 1.3.
A list of changes between 1.3.1 and 1.3.2 is
- Don't panic in cluster_rbuild when DIAGNOSTIC is defined - just count
the number of times we hit the "too much memory" case.
- Fix a security hole in vm_mmap.c as described on bugtraq.
- Fix a bug in uipc_usrreq.c which could be exploited to cause a panic.
- Fix I/O region mapping bug on EISA Buslogic cards.
- Fix problem with synchronous opens and mounts (from Lite2)
- Now that O_FSYNC works, give it the symbol that XPG4.2 expects, and
document all of this.
- Fix an NFS client crash that happened with a combination of amd and
Linux or SVR4 binaries.
- Fix a problem where the NFS client code would not recover from
a TCP connection being broken (mount point dead; reboot needed).
(Solaris 2.5.1 NFS servers close TCP connections after 400
seconds of idletime.)
- A trivial NULL-protect fix to the hp300-derived pmaps can protect
kernels from crashing in certain rare conditions possibly related to
paging activity, or in a more easily reproduced case where mlock()
is used with any kind of shared vm map.
- Fix the in_cksum odd-byte starting/finishing case for big-endian as
well as little-endian. (from PR 4434).
- Avoid some deadlocks that can show up on diskless systems or when
doing NFS paging.
Kernel networking changes:
- Fix the TCP/IP "stretch ACK violation" bug documented in internet
draft draft-ietf-tcpimpl-prob-02.txt. Also, fix another bug in
the header prediction case where an ACK would not be sent when it
- Implement tcp_drain().
- Ensure the TCP persist timer is running if the send window reaches
zero. Part of the fix for kern/2335 (email@example.com).
- If we fail to allocate mbufs for the outgoing TCP segment, free the
header and abort.
- When running the slow TCP timer, skip PCBs in LISTEN state.
- When processing the TCP persist timer, drop the connection if the
connection idle time exceeds the maximum backoff for retransmit.
Part of kern/2335 (firstname.lastname@example.org).
- Implement a queue for TCP delayed ACK processing. This queue is
used in tcp_fasttimo() in lieu of scanning all open TCP connections.
- Finishing merging 4.4BSD-Lite2 netinet. At this point, the only changes
left were SCCS IDs and Copyright dates. Need to do this since some
of the above comes from Lite2.
- Fix an mbuf leak and a possible use of an mbuf after it has been
freed, in the TCP input code.
- Fix a TCP bug that would cause a FIN at the end of some data not to
be ACKed, requiring an additional packet exchange in order to close
- Fix a bug in the SYN cache code that could time out a SYN cache
entry far too soon under certain circumstances.
- Add some multicast defines to netinet/in.h
- allow receipt of more than one message in recvmsg syscall.
Fixes PR#4700 (Jean-Luc Richier).
- Make insertion and removal of sockets from the partial and incoming
connection queue O(constant) rather than O(N).
Generic device driver changes:
- Fix vnd bug that required us to flush all buffers (and caused
unpredictable lossage when that didn't work).
- Allow NE2000 boards to work on Alphas (alignment fixup).
- Fix a big-endian problem on the ne2000.
- Align mbufs for ne2000 so that 16-bit PIO will never cause unaligned
- Some bug fixes to the PCMCIA 3c589 driver.
- Some bus_space improvements to the Intel Etherexpress Pro 10/100
(fxp) driver to make it work on (e.g.) the Alpha.
- Support additional Soundblaster cards.
- Make more wd and sd device nodes by default on i386.
- Fix keyboard lockup problem on some i386 machines.
- Floating point context switch fixes for i386
- Fix a long-standing i386 floating point bug in other-OS emulation:
the FPU wasn't initialized properly.
- In fdisk, when estimating the number of cylinders in the BIOS
geometry, use the total number of sectors as reported by
disklabel.d_secperunit rather than multiplying out the disklabel
geometry, which is less accurate.
- In fdisk, don't print "DOS partition initialized" if -S flag is
specified; from Nathan Williams in PR bin/4893.
- Fix fdisk a nasty sysinst problem that occurred with disks that
had a DOS Master Boot Record.
- Fix some incompatibilities in FreeBSD compatibility code.
- Report Cyrix 686-class CPU class correctly.
- Fix 68060 signal handling in Amiga port.
- Close a hole allowing Amiga kernels to be crashed from userland.
- Turn off grfdebug messages by default.
- Use the right ADB chip on Mac Classic and Classic II.
- NetBSD/mac68k can run an X server on the Quadra 700 now.
- Fix a NetBSD/mac68k problem where the ADB probe hangs when some
types of devices are connected or when no mouse is connected).
- Amiga ite driver documentation updated.
- Add a configure option that allows a kernel to be built that limits
the amount of physical memory the amiga port will use. This allows
an install kernel to be built that works both on machines with small
amounts of memory and machines with a lot of memory. A cleaner fix
will be available in 1.4.
- Fix a problem in the pmax port with DECstation 100 mice.
- Put NETATALK netisr back into trap.c (now sys/arch/mips/mips/trap.c).
- Fix the kernel built from the "DS5000_200" config file (pmax port).
- Fix spurious dma errors in scsi dma operation noticed on Sun 4/300
- Work around a hardware quirk on MicroSparc II processors.
- A version of the Alpha compiler toolchain modifications whose
copyright is not owned by CMU. This is not yet guaranteed to
work - the preferred development system is still the binary
distribution based on the CMU-copyrighted changes.
- Fix PR#4903 - a problem with the isp driver on the Alpha port.
Userland library/include/makefile changes:
- Fix MI/MD PLIST problem on pmax (bsd.port.mk)
- Fix 'int' vs. 'char' lossage in m4 for unsigned-char machines.
- Fix problems in m4 with 0xff being interpreted as EOF in some places,
causing incorrect output and/or output that was inconsistent between
different NetBSD ports.
- Many Year 2000 fixes
- Fix an ABI problem in the stat structure on 64-bit architectures.
- Fix quad (64-bit) shifts on certain architectures.
Userland program fixes:
- Fix some minor nits in /bin/login.
- Fix a rather large hole in ftpd. Guest users were allowed to use
the rename command.
- Many gdb bugs fixed.
- Many improvements to the share/mk/bsd.port*.mk Makefile header, which
is used to build NetBSD packages. Some changes were required in
bsd.own.mk to support this.
- Some Makefile changes to build some utilities that are not
necessarily installed on a system with full development binaries.
- The default sendmail.cf causes /etc/aliases to be rebuilt whenever
sendmail notices that it's changed, rather than sendmail complaining
about it in the system logs.
- Add a magic number for wordperfect files.
- Many installation notes updated and/or clarified.
- Fix a bug in the sysinst factoring code that would identify perfect
squares as prime.
- Some architecture-specific fixes - see your favourite architecture
for more information.
- Pathname fixes for CD installations.
- Expand ftp server documentation.
- Don't imply that we have a FORTRAN compiler in install notes.
- Document some features in printcap that many people want but don't
know already exist.
