Linux kernel source tree
fac08d45e2
Drop the log_size>0 and log_buf!=NULL condition when log_level>0. This allows users to request log_true_size of a full log without providing actual (even if small) log buffer. Verifier log handling code was mostly ready to handle NULL log->ubuf, so only few small changes were necessary to prevent NULL log->ubuf from causing problems. Note, that if user provided NULL log_buf with log_level>0 we don't consider this a log truncation, and thus won't return -ENOSPC. We also enforce that either (log_buf==NULL && log_size==0) or (log_buf!=NULL && log_size>0).

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.
