Raw File
Take a new snapshot of a software origin
If the archived software origin currently browsed is not synchronized with its upstream version (for instance when new commits have been issued), you can explicitly request Software Heritage to take a new snapshot of it.
Use the form below to proceed. Once a request has been submitted and accepted, it will be processed as soon as possible. You can then check its processing state by visiting this dedicated page.![swh spinner](/static/img/swh-spinner.gif)
Processing "take a new snapshot" request ...
Permalinks
To reference or cite the objects present in the Software Heritage archive, permalinks based on SoftWare Hash IDentifiers (SWHIDs) must be used.
Select below a type of object currently browsed in order to display its associated SWHID and permalink.

BPF Documentation
=================
This directory contains documentation for the BPF (Berkeley Packet
Filter) facility, with a focus on the extended BPF version (eBPF).
This kernel side documentation is still work in progress. The main
textual documentation is (for historical reasons) described in
`Documentation/networking/filter.txt`_, which describe both classical
and extended BPF instruction-set.
The Cilium project also maintains a `BPF and XDP Reference Guide`_
that goes into great technical depth about the BPF Architecture.
The primary info for the bpf syscall is available in the `man-pages`_
for `bpf(2)`_.
