Complete source and binaries for NetBSD 7.0 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 https://www.NetBSD.org/mirrors/. We encourage users who wish to install via ISO or USB disk images to download via BitTorrent by using the torrent files supplied in the images area. A list of hashes for the NetBSD 7.0 distribution has been signed with the well-connected PGP key for the NetBSD Security Officer: https://ftp.NetBSD.org/pub/NetBSD/security/hashes/NetBSD-7.0_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:
- Add sendmmsg(2) and recvmmsg(2) support.
- Add BPF coprocessor support (BPF_COP/BPF_COPX instructions).
- Add fdiscard(2) and posix_fallocate(2) system calls.
- Add a new RLIMIT_NTHR limit to limit the number of processes per user and the corresponding kern.maxlwp sysctl.
- Import sljit and add BPF JIT compiler.
- Expose kern.uidinfo.* via sysctl.
- Create an "options MODULAR_DEFAULT_AUTOLOAD" config option and add it to all kernel configs that contain "options MODULAR". This option turns on module autoloading by default (which is the current default). This allows people who don't want module autoloading on by default to disable it by simply removing/commenting this line.
- kqueue(2): on NOTE_EXIT, put the exit code of the process in "data".
- sysmon_pswitch(9): Introduce a new switch type, PSWITCH_TYPE_RADIO, to be used to report to userland hardware radio switch changes. powerd(8) will call a "radio_button" script to handle the event.
- envsys(4): Add %rH (relative Humidity) to sensor framework.
Add sysctls to avoid IPv6 DoS attacks (from OpenBSD):
- net.inet6.ip6.neighborgcthresh = 2048
- net.inet6.ip6.maxifprefixes = 16
- net.inet6.ip6.maxifdefrouters = 16
- net.inet6.ip6.maxdynroutes = 4096
- Make shmif(4) work with bridges.
- Add net.inet6.ip6.prefer_tempaddr sysctl knob to prefer IPv6 temporary addresses as the source address.
- Add support for the TCP_INFO socket option, which permits the caller to query certain information about a TCP connection.
- ptyfs: Allow multiple mounts and support proper device visibility in chroots.
- Enable support for UFS1 extended attributes in GENERIC and GENERIC-like kernels.
- FFS: Don't fail mounting the root filesystem if the WAPBL log is corrupt.
- Add experimental support for the (mostly SSD specific) "discard", or ATA "TRIM" command to wd(4) and FFS.
- Sensors can now be a source of entropy.
- Gather much more entropy early in boot and thereafter: autoconf timings, all sysctl settings (including hostname), contents of early network packets, environmental sensor values generically rather than as per-driver special cases.
- Add explicit enable/disable hooks for callout-driven sources (be more power friendly).
- Make "skew" source polled so it runs only when there is entropy demand.
- Adjust entropy collection from polled sources so it's processed sooner.
- Add viornd(4), a driver for the VirtIO entropy source available on QEMU, KVM, and Google Compute Engine.
- cprng_fast(9): Replace slow/broken mutex-protected kernel _arc4random() with new cprng_fast implementation using per-cpu instances of chacha8.
- ess(4): Add support for Spatializer, 3D audio effects embedded in ES1869 and ES1879.

The NetBSD Foundation would like to thank all those who have contributed code, hardware, documentation, funds, colocation for our servers, web pages and other documentation, release engineering, and other resources over the years. More information on the people who make NetBSD happen is available at:
We would like to especially thank the University of California at Berkeley and the GNU Project for particularly large subsets of code that we use. We would also like to thank the Internet Systems Consortium Inc. and the Network Security Lab at Columbia University's Computer Science Department for current colocation services.
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.
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.
Donations can be done via PayPal to
<paypal@NetBSD.org>, or via Google Checkout and are fully
tax-deductible in the US. See
