Introduction

The NetBSD Project is pleased to announce NetBSD 11.1, the first point release of the NetBSD 11 stable branch.

Upgrade instructions

An existing installation can be upgraded by booting an installation image and selecting the Upgrade option.

If you are using other update methods, update the kernel and modules first, then reboot and update your userspace.

Changes since NetBSD 11.0

This release primarily focuses on security and bug fixes, since our aim was to get it released as soon as possible to address certain security issues.

Ports

  • alpha: Fixed a boot hang occurring on unpatched QEMU.
  • alpha: Fixed kernel stack pointer alignment leading to panics during test suite runs. (PR 60865)
  • amd64, i386: Reduced the strictness of the "WARNING: no TOD clock present" check.
  • amd64, i386: Fixed a panic on the Zhaoxin KX-7000 and other late-model CPUs from VIA/Zhaoxin.
  • amd64: Fixed libc behaviour when calling memchr(3) with certain unusual arguments. (PR 60744)
  • atari: Fixed ATARITT kernels failing to boot on Atari TT030.
  • evbarm: Fixed stability problems with certain USB devices on Raspberry Pi.
  • evbarm: Fixed thread local storage on ARMv5 with soft floats. (PR 57638)
  • evbarm: Fixed "am335x omaptimer fails to attach". (PR 60910)
  • hppa: Added support for eager FPU switching. Currently enabled only for QEMU to work around an emulation bug, may eventually become the default for improved safety.

  • sparc64: Added support for the i2c controller found in Pyro-based machines (e.g. Sun Ultra 45, Sun Fire V245).
  • sparc64: Added support for the real-time clock used in the Sun Ultra 45.
  • sun68k: Fixed booting from SCSI disks with certain PROM revisions.

Kernel and MI device drivers

  • ffs: Fixed an uvm_fault occurring during snapshot dump/restore. (PR 59663)
  • ipfilter: Fixed a NULL pointer dereference leading to potential DoS while parsing ICMP6 packets. (PR 60484)
  • net: Fixed an off-by-error in a bounds check in bsd_decompress().
  • uvm: Fixed a race condition in the page daemon.
  • vfs: Limit snapshot-related vflushbuf: dirty: vnode [...] console spew under heavy load.
  • acpibat(4): Added support for battery monitoring on the Microsoft Surface Go 3.
  • hdaudio(4): Apply access checks to configuration operations on /dev/hdaudioX. (PR 60492)
  • ixl(4): Fixed driver hang, then failure on ifconfig, if SFP module present at boot time and media connected. (PR 60736)
  • mpii(4): Fixed stability of Symbios Logic SAS3008 RAID controllers. (PR 58684)
  • raid(4): Fixed an incorrect assertion during reconstruction. (PR 60477)
  • run(4), rum(4), various other USB Wi-Fi drivers: Fixed a kernel panic seen when hotplugging a device with wpa_supplicant(8) running. (PR 60665)
  • virtio(4): Improve documentation.
  • vr(4): Fixed stability problems observed after warm reboots. (PR 60848)
  • wdc(4): Avoid a three-second delay during boot with PCI IDE controllers.

Userspace and build system

  • build.sh: Fixed building certain legacy GPLv2 GNU tools with modern compilers; used for GCC compiler bootstrapping.
  • build.sh: Fixed building with MKBINUTILS=no set.
  • build.sh: Fixed cross-builds from MacOS on Apple Silicon. (PR 60904)

  • build.sh: Generate hashes for bootable images in the gzimg directory. (PR 59195, PR 60302)
  • libc: Fixed issues with printf(3) thousands separators and positional arguments. (PR 60708, PR 60496)
  • ld.elf_so(1): Fixed incorrect thread-local storage alignment assertions with DEBUG enabled.
  • wgetscrreg(3): Added a manual page.
  • httpd(8): Clarified documentation of CGI options.

About NetBSD

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 vibrant international community. Many applications are readily available through pkgsrc, the NetBSD Packages Collection.

About the NetBSD Foundation

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 to help with ongoing upgrades and maintenance, as well as with operating expenses for the NetBSD Foundation.
