It is possible that the first event in the event log is not actually a
log header at all, but rather a normal event. This leads to the cast in
__calc_tpm2_event_size being an invalid conversion, which means that
the values read are effectively garbage. Depending on the first event's
contents, this leads either to apparently normal behaviour, a crash or
a freeze.
While this behaviour of the firmware is not in accordance with the
TCG Client EFI Specification, this happens on a Dell Precision 5510
with the TPM enabled but hidden from the OS ("TPM On" disabled, state
otherwise untouched). The EFI firmware claims that the TPM is present
and active and that it supports the TCG 2.0 event log format.
Fortunately, this can be worked around by simply checking the header
of the first event and the event log header signature itself.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
