This fixes recvmsg() to be able to peek across multiple tls records. Without this patch, the tls's selftests test case 'recv_peek_large_buf_mult_recs' fails. Each tls receive context now maintains a 'rx_list' to retain incoming skb carrying tls records. If a tls record needs to be retained e.g. for peek case or for the case when the buffer passed to recvmsg() has a length smaller than decrypted record length, then it is added to 'rx_list'. Additionally, records are added in 'rx_list' if the crypto operation runs in async mode. The records are dequeued from 'rx_list' after the decrypted data is consumed by copying into the buffer passed to recvmsg(). In case, the MSG_PEEK flag is used in recvmsg(), then records are not consumed or removed from the 'rx_list'. Signed-off-by: Vakul Garg <vakul.garg@nxp.com> Signed-off-by: David S.

README
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.
