Samples added to the entropy pool in hard interrupt context are only buffered, never processed directly, and if they fill the buffer, the sample is dropped -- this serves to encourage taking timing samples in hard interrupt context because it's cheap, and we have no idea how many samples we really need for full entropy so it's safer to err on the side of `as many as we can get'. But for viornd(4), we assume the host has full entropy so we only need a single 32-byte sample, and we want to avoid dropping it so we get full entropy ASAP. Entering the sample in a soft interrupt rather than hard interrupt achieves this. |

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.
Building
You can cross-build NetBSD from most UNIX-like operating systems. To build for amd64 (x86_64), in the src directory:
./build.sh -U -u -j4 -m amd64 -O ~/obj release
Additional build information available in the BUILDING file.
Binaries
Testing
On a running NetBSD system:
cd /usr/tests; atf-run | atf-report
Troubleshooting
- Send bugs and patches via web form.
- Subscribe to the mailing lists. The netbsd-users list is a good choice for many problems; watch current-users if you follow the bleeding edge of NetBSD-current.
- Join the community IRC channel #netbsd @ libera.chat.
Latest sources
To fetch the main CVS repository:
cvs -d anoncvs@anoncvs.NetBSD.org:/cvsroot checkout -P src
To work in the Git mirror, which is updated every few hours from CVS:
git clone https://github.com/NetBSD/src.git
