Michael Brown 6872d143d6 [tls] Discard received Change Cipher records under TLS version 1.3
TLS version 1.3 allows unencrypted Change Cipher records to be sent
after switching to use the handshake traffic keys.  This is an ugly
protocol hack to work around badly implemented firewalls of the kind
beloved by large organisations.

Ignore and discard any such records, which would otherwise cause
decryption failures.

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.
