Eric Dumazet says: ==================== tcp: take care of empty skbs in write queue We understood recently that TCP sockets could have an empty skb at the tail of the write queue, leading to various problems. This patch series : 1) Make sure we do not send an empty packet since this was unintended and causing crashes in old kernels. 2) Change tcp_write_queue_empty() to not be fooled by the presence of an empty skb. 3) Fix a bug that could trigger suboptimal epoll() application behavior under memory pressure. ==================== Signed-off-by: Jakub Kicinski <jakub.kicinski@netronome.com> |

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.
