Announcing NetBSD 5.0.1
The NetBSD Project is pleased to announce that version 5.0.1 of the NetBSD operating system is now available. NetBSD 5.0.1 is the first security/critical update of the NetBSD 5.0 release branch. It represents a selected subset of fixes deemed critical in nature for security or stability reasons.
Please note that all fixes in security/critical updates (i.e., NetBSD 5.0.1, 5.0.2, etc.) are cumulative, so the latest update contains all such fixes since the corresponding minor release. These fixes will also appear in future minor releases (i.e., NetBSD 5.1, 5.2, etc.), together with other less-critical fixes and feature enhancements.
Complete source and binaries for NetBSD 5.0.1 are available for download at many sites around the world. A list of download sites providing FTP, AnonCVS, SUP, and other services may be found at http://www.NetBSD.org/mirrors/. We encourage users who wish to install via ISO images to download via BitTorrent by using the torrent files supplied in the ISO image area. A list of hashes for the NetBSD 5.0.1 distribution has been signed with the well-connected PGP key for the NetBSD Security Officer: ftp://ftp.NetBSD.org/pub/NetBSD/security/hashes/NetBSD-5.0.1_hashes.asc
NetBSD is free. All of the code is under non-restrictive licenses, and may be used without paying royalties to anyone. Free support services are available via our mailing lists and website. Commercial support is available from a variety of sources. More extensive information on NetBSD is available from our website:
Your donation to the NetBSD Foundation allows the project to make major improvements to the code base. We would like to take this opportunity to remind everyone that we are in the middle of a fund drive with a target of 60,000 USD by the end of the year. We would like to continue funded development in various areas, including:
- Improving network stack concurrency and performance.
- Development of modern file systems and improvement of existing ones.
- Features which are useful in embedded environments, for example, high resolution timers and execute in place (XIP) support.
- Automatic testing and quality assurance.
The complete list of changes can be found in the CHANGES-5.0.1 file in the top level directory of the NetBSD 5.0.1 release tree. An abbreviated list is as follows:
- NetBSD-SA2009-004, NetBSD OpenPAM passwd(1) changing weakness.
- NetBSD-SA2009-005, Plaintext Recovery Attack Against SSH.
- NetBSD-SA2009-006, Buffer overflows in ntp.
- NetBSD-SA2009-007, Buffer overflows in hack(6).
- NetBSD-SA2009-008, OpenSSL ASN1 parsing denial of service and CMS signature verification weakness.
- NetBSD-SA2009-009, OpenSSL DTLS Memory Exhaustion and DSA signature verification vulnerabilities.
- NetBSD-SA2009-010, ISC dhclient subnet-mask flag stack overflow.
- NetBSD-SA2009-011, ISC DHCP server Denial of Service vulnerability.
- NetBSD-SA2009-012, SHA2 implementation potential buffer overflow.
- NetBSD-SA2009-013, BIND named dynamic update Denial of Service vulnerability.
Note: Advisories prior to NetBSD-SA2009-004 do not affect NetBSD 5.0.
- Fix random "filesystem full" messages on large FFS file systems.
- Fix a regression in the 4.4BSD scheduler, improving interactive performance under load.
- Remove a race where physio_done() may use memory already freed. Fixes PR kern/39536.
- Fix a crash observed when trying to load a corrupted ELF kernel module.
- Fix PR kern/41566, where writes on the controlling tty were not being awoken from blocks.
- Various fixes for POSIX message queues.
- Fix a possible deadlock in the VFS subsystem.
- Fixes for POSIX advisory locks.
- A number of other stability fixes.
- Follow exactly the recommendation of draft-ietf-tcpm-tcpsecure-11.txt: Don't check against the last ack received, but the expected sequence number. This makes RST handling independent of delayed ACK.
- Fix a panic when trying to disable IPFilter before enabling it. Fixes PR kern/41364.
- ehci(4): Add a workaround for ATI SB600 and SB700 revisions A12 and A13 to avoid a USB subsystem hang when the system has multiple USB devices connected to it or one device is re-connected often.
- On i82563, FreeBSD's em driver says that the ready bit in the MDIC register may be incorrectly set. Insert delay(200) like the em driver. Fixes PR kern/41014.
- Add workaround for 82543GC. We need to force speed and duplex on the MAC equal to what the PHY speed and duplex configuration is. Fixes PR kern/36430.
- Fix many problems and panic on TBI's cards (PR kern/32009).
- x86 (amd64 and i386): Add a workaround for a bug with some Opteron revisions where locked operations sometimes do not serve as memory barriers, allowing memory references to bleed outside of critical sections.
- amd64: Handle protection faults properly, returning SIGSEGV instead of SIGBUS.
- hp300: Make install.md probe cd(4) devices properly.
- pmax: Make ksyms(4) actually work.
- sh3: Fix logic error in copyinstr() when deciding whether to return EFAULT or ENAMETOOLONG.
- Fix long double support in 32bit libc. Fixes PR port-sparc64/41406.
- When preparing the initial trap frame for a new forked lwp, explicitly clear condition code. Otherwise we might catch a signal before we ever return to userland. Fixes PR port-sparc64/41302.
- vax: binutils: Allocate relocation section using bfd_zalloc() to ensure no garbage relocations when not all the entries are used. Fixes PR port-vax/39182.
Update pkg_install to 20090724.
Notepkg_install now depends on the pkgdb cache for automatic conflict detection. It is recommended to rebuild the cache with "pkg_admin rebuild". audit-packages.conf(5) has been superseded by pkg_install.conf(5). The default configuration is the same. Support for pkg_view(1) has been retired. The functionality of audit-packages(1) and download-vulnerability-list(1) has moved into pkg_admin(1). Wrapper scripts that handle the common use cases are provided.
- Update libfetch to 2.23.
- racoonctl(8): Adjust ADMINPORTDIR to match that of racoon (/var/run). Fixes PR bin/41376.
- schedctl(8): Skip LSIDL and LSZOMB threads when retrieving info.
- postinstall(8) now knows about /etc/dhcpcd.conf.
- The X.Org s3 driver now works.
- Install the Xvidtune app-defaults file.
Fixes to Linux compat:
- In sendmsg(2), do copy the msghdr structure before trying to use it.
- In linux_sys_sched_getaffinity(), do not leak memory on error.
- Various METALOG fixes, including sorting entries. Addresses PR toolchain/24457 and PR bin/41155.
Using block device nodes directly for I/O may cause a kernel crash when the file system containing /dev is FFS and is mounted with -o log. Workaround: use raw disk devices, or remount the file system without -o log.
Occasionally, gdb may cause a process that is being debugged to hang when "single stepped". Workaround: kill and restart the affected process.
gdb cannot debug running threaded programs correctly. Workaround: generate a core file from the program using gcore(1) and pass the core to gdb, instead of debugging the running program.
Statically linked binaries using pthreads are currently broken.

NetBSD is a free, fast, secure, and highly portable Unix-like Open Source operating system. It is available for a wide range of platforms, from large-scale servers and powerful desktop systems to handheld and embedded devices. Its clean design and advanced features make it excellent for use in both production and research environments, and the source code is freely available under a business-friendly license. NetBSD is developed and supported by a large and vivid international community. Many applications are readily available through pkgsrc, the NetBSD Packages Collection.
The NetBSD Foundation was chartered in 1995, with the task of overseeing core NetBSD project services, promoting the project within industry and the open source community, and holding intellectual property rights on much of the NetBSD code base. Day-to-day operations of the project are handled by volunteers.
As a non-profit organization with no commercial backing, The NetBSD Foundation depends on donations from its users, and we would like to ask you to consider making a donation to the NetBSD Foundation in support of continuing production of our fine operating system. Your generous donation would be particularly welcome assistance with ongoing upgrades and maintenance, as well as with operating expenses for The NetBSD Foundation.
