During this month I've finished the needed work in the base distribution in order to host fully featured LLDB.
Currently the ptrace(2) interfaces in NetBSD are, in terms of features, closely related to FreeBSD and Linux.
There are only few bugs left with filed Problem Reports and alerting regression tests,
however they do not interfere with the needed functions to move the port of the debugger forward.[Read More

Today (2017-02-20) NetBSD got our first reproducible build on the debian build farm
. Here's a short description how we got here, what implementation choices we made, and what we had to fix.[Read More

The LLVM project is a quickly moving target, this also applies to the LLVM debugger -- LLDB. It's actively used in several first-class operating systems, while - thanks to my spare time dedication - NetBSD joined the LLDB club in 2014, only lately the native support has been substantially improved and the feature set is quickly approaching the support level of Linux and FreeBSD. During this work 12 patches were committed to upstream, 12 patches were submitted to review, 11 new ATF were tests added, 2 NetBSD bugs filed and several dozens of commits were introduced in pkgsrc-wip, reducing the local patch set to mostly Native Process Plugin for NetBSD.[Read More

Keeping a current firefox working is a tough task. All NetBSD architectures are "tier 3" from the Mozilla foundations point of view.
Onodera-san (who does most of the pkgsrc work for mozilla based pkgs - and others) does a great job.
And on "strange" architectures like sparc64 it is even worse...

Operating systems can be called monitors as they handle system calls from userland processes. A similar task is performed by debuggers as they implement monitors for traced applications and interpret various events that occurred in tracees and are messaged usually with signals to their tracers. During this month I have started a new Process Plugin within LLDB to incept NativeProcessNetBSD - copied from NativeProcessLinux - implementing basic functionality and handling all the needed events in the MonitorCallback() function. To achieve these tasks, I had to add a bunch of new ptrace(2) interfaces in the kernel to cover all that is required by LLDB monitors. The current Process Plugin for NetBSD is capable to start a process, catch all the needed events correctly and if applicable resume or step the process.[Read More

NetBSD.org DNS is down because our secondary stopped serving our zone and the network of our primary went offline.
[Update, 2017-01-16 20:48 UTC: NetBSD.org is back up now.]

The NetBSD Foundation took part in the 2016 Google Summer of Code
Hrishikesh Goyal worked on the project "Implement Ext4fs support in ReadOnly mode".
He tackled two features of an ext4fs implementation: extents and
HTree DIR read/write support. His work was committed into the NetBSD
source tree in multiple commits.
charles cui worked on adding tests for better "POSIX Test Suite
Compliance". This involved porting the Open Posix benchmark
suite to NetBSD. Many of the tests showed missing features, and
Charles worked with his mentors to improve the results. See his
summary for details.
Leonardo Taccari worked on "Split debug symbols for pkgsrc builds". He already blogged about this in much detail on this blog.
A big thank you to Google for sponsoring the students to work on
NetBSD, the students for working on the projects, and the mentors that
were helping them along!

In short, we are already in a good state with the existing ptrace(2) interfaces, as most necessary functions in LLDB are representable by existing NetBSD specific interfaces. We can fully implement core LLDB functionality without further extensions in ptrace(2). During this project dozen of bugs were investigated & fixed and several hundreds of ATF tests added. The major addition is newly added support for hardware assisted watchpoints API for ptrace(2) on amd64 and preliminary code for i386 and XEN.[Read More

The NetBSD Project is pleased to announce NetBSD 7.0.2, the second security/bugfix update of the NetBSD 7.0 release branch. It represents a selected subset of fixes deemed important for security or stability reasons. If you are running an earlier release of NetBSD, we strongly suggest updating to 7.0.2.
For more details, please see the release notes.
Complete source and binaries for NetBSD 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/.

The NetBSD Foundation has initiated a contract with Kamil Rytarowski
to complete the following during it:
1. Add missing interfaces in ptrace(2), mostly sync it with
the FreeBSD capabilities, add ATF tests, add documentation.
2. Develop process plugin in LLDB based on the FreeBSD code in
LLDB and make it functional (start passing at least some tests).
3. Revamp the process plugin in LLDB for new remote debugging
capabilities (in order to get it accepted and merged upstream),
pass more tests.
4. LLDB x86 support, pass more of the standard LLDB tests
and import LLDB to the NetBSD base. Add some ATF LLDB basic
functionality tests to the tree. The original tests are
unreliable and generate false positives.
5. Develop missing features needed for .NET (POSIX robust
mutexes), add ATF tests.
6. Develop missing features for VirtualBox as host, including
needing sigevent(2) on par with POSIX and SIGEV_KEVENT, and
other real-time AIO related interfaces as needed.
7. Port Apple's Swift programming language. Enhance .NET port to
validate new interface and correct more issues as needed.
8. Improve VirtualBox host support. Make it build first by disabling
missing features of providing empty facades for them.
9. Implement CDROM, floppy, NIC support for NetBSD in VBox as host.
10. Make VirtualBox runnable at least with a restricted feature set, ship
it in pkgsrc, and submit it upstream.
The NetBSD Foundation will continue to work diligently with the
community to fund projects furthering specific key and quality
improvements to the NetBSD projects. We have a list of projects at
http://wiki.netbsd.org/projects/ as well as welcome other proposals
to move our flag forward to next releases!
Thank you to Kamil for committing to it and we all look forward to it!
