Michael Brown 65450656e5 [tls] Add a standalone TLS data structure builder
Provide a generic builder that can construct an arbitrary TLS data
structure based upon the same descriptors and binary-encoded mappings
as used for the generic parser.

The design allows for the caller to either provide data in advance or
to write through the descriptor pointers after building the data
structure.  For example: this will allow the public key within a
ClientHello to be populated in situ within the key_share extension,
rather than requiring the caller to allocate and populate a temporary
buffer before building the ClientHello.

This necessitates removing the "const" from all pointers within the
descriptors, which is a worthwhile tradeoff for the sake of avoiding a
large number of temporary allocations.

iPXE network bootloader

Build Coverity Release

iPXE is the leading open source network boot firmware. It provides a full PXE implementation enhanced with additional features such as:

  • boot from a web server via HTTP or HTTPS,

  • boot from an iSCSI, FCoE, or AoE SAN,

  • control the boot process with a script,

  • create interactive forms and menus.

You can use iPXE to replace the existing PXE ROM on your network card, or you can chainload into iPXE to obtain the features of iPXE without the hassle of reflashing.

iPXE is free, open-source software licensed under the GNU GPL (with some portions under GPL-compatible licences).

You can download the rolling release binaries (built from the latest commit), or use the most recent stable release.

For full documentation, visit the iPXE website.
