Neal Cardwell says: ==================== tcp: 3 fixes for retrans_stamp and undo logic Geumhwan Yu <geumhwan.yu@samsung.com> recently reported and diagnosed a regression in TCP loss recovery undo logic in the case where a TCP connection enters fast recovery, is unable to retransmit anything due to TSQ, and then receives an ACK allowing forward progress. The sender should be able to undo the spurious loss recovery in this case, but was not doing so. The first patch fixes this regression. Running our suite of packetdrill tests with the first fix, the tests highlighted two other small bugs in the way retrans_stamp is updated in some rare corner cases. The second two patches fix those other two small bugs. Thanks to Geumhwan Yu for the bug report! ==================== Link: https://patch.msgid.link/20241001200517.2756803-1-ncardwell.sw@gmail.com Signed-off-by: Jakub Kicinski <kuba@kernel.org>
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.
