On receipt of a complete tls record, use socket's saved data_ready callback instead of state_change callback. In function tls_queue(), the TLS record is queued in encrypted state. But the decryption happen inline when tls_sw_recvmsg() or tls_sw_splice_read() get invoked. So it should be ok to notify the waiting context about the availability of data as soon as we could collect a full TLS record. For new data availability notification, sk_data_ready callback is more appropriate. It points to sock_def_readable() which wakes up specifically for EPOLLIN event. This is in contrast to the socket callback sk_state_change which points to sock_def_wakeup() which issues a wakeup unconditionally (without event mask).

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.
See Documentation/00-INDEX for a list of what is contained in each file.
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.
