Michael Brown 8c7c084e0f [crypto] Fail all operations for the null public-key algorithm
The null crypto algorithms are intended to do nothing: the null digest
algorithm accepts all input and generates a zero-length digest, and
the null cipher algorithm simply copies the input unmodifed to the
output.

The null public-key algorithm currently does nothing successfully.
Unlike the null digest and cipher algorithms, the null public-key
algorithm's methods are never called.

Change the null public-key algorithm to fail all operations, thereby
allowing its methods to be used as stubs by algorithms such as ECDSA
that do not implement all of the possible public-key operations.

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.
