Michael Brown 009bcf17a0 [tls] Treat signature algorithm identifiers as opaque 16-bit values
RFC 5246 defines the signature_algorithm extension values for TLS
version 1.2 as being tuples of {HashAlgorithm, SignatureAlgorithm}
pairs.  RFC 8446 redefines the signature_algorithm extension values
for TLS version 1.3 in a backwards-compatible way as opaque 16-bit
SignatureScheme values, and RFC 8447 updates RFC 5246 to allow these
values to be used with TLS version 1.2.

Redefine our concept of a signature algorithm identifier to remove the
internal structure that no longer exists.

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.
