Eric Biggers 23b8b188cb crypto: drbg - Fix returning success on failure in CTR_DRBG
commit 39a31ad9e2 upstream.

drbg_ctr_generate() sometimes returns success when it fails, leaving the
output buffer uninitialized.  Fix it.

Fixes: cde001e4c3 ("crypto: rng - RNGs must return 0 in success case")

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 reStructuredText 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.
