[ Upstream commit f7fa16d49837f947ee59492958f9e6f0e51d9a78 ]
With mixed sync/async decryption, or failures of crypto_aead_decrypt,
we increment decrypt_pending but we never do the corresponding
decrement since tls_decrypt_done will not be called. In this case, we
should decrement decrypt_pending immediately to avoid getting stuck.
For example, the prequeue prequeue test gets stuck with mixed
modes (one async decrypt + one sync decrypt).
Fixes: 94524d8fc9 ("net/tls: Add support for async decryption of tls records")

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.
