Tony Jones 451830a94b apparmor: Fix network performance issue in aa_label_sk_perm [ Upstream commit `5f997580e8` ] The netperf benchmark shows a 5.73% reduction in throughput for small (64 byte) transfers by unconfined tasks. DEFINE_AUDIT_SK() in aa_label_sk_perm() should not be performed unconditionally, rather only when the label is confined. netperf-tcp `56974a6fc`^ `56974a6fc` Min 64 563.48 ( 0.00%) 531.17 ( -5.73%) Min 128 1056.92 ( 0.00%) 999.44 ( -5.44%) Min 256 1945.95 ( 0.00%) 1867.97 ( -4.01%) Min 1024 6761.40 ( 0.00%) 6364.23 ( -5.87%) Min 2048 11110.53 ( 0.00%) 10606.20 ( -4.54%) Min 3312 13692.67 ( 0.00%) 13158.41 ( -3.90%) Min 4096 14926.29 ( 0.00%) 14457.46 ( -3.14%) Min 8192 18399.34 ( 0.00%) 18091.65 ( -1.67%) Min 16384 21384.13 ( 0.00%) 21158.05 ( -1.06%) Hmean 64 564.96 ( 0.00%) 534.38 ( -5.41%) Hmean 128 1064.42 ( 0.00%) 1010.12 ( -5.10%) Hmean 256 1965.85 ( 0.00%) 1879.16 ( -4.41%) Hmean 1024 6839.77 ( 0.00%) 6478.70 ( -5.28%) Hmean 2048 11154.80 ( 0.00%) 10671.13 ( -4.34%) Hmean 3312 13838.12 ( 0.00%) 13249.01 ( -4.26%) Hmean 4096 15009.99 ( 0.00%) 14561.36 ( -2.99%) Hmean 8192 18975.57 ( 0.00%) 18326.54 ( -3.42%) Hmean 16384 21440.44 ( 0.00%) 21324.59 ( -0.54%) Stddev 64 1.24 ( 0.00%) 2.85 (-130.64%) Stddev 128 4.51 ( 0.00%) 6.53 ( -44.84%) Stddev 256 11.67 ( 0.00%) 8.50 ( 27.16%) Stddev 1024 48.33 ( 0.00%) 75.07 ( -55.34%) Stddev 2048 54.82 ( 0.00%) 65.16 ( -18.86%) Stddev 3312 153.57 ( 0.00%) 56.29 ( 63.35%) Stddev 4096 100.25 ( 0.00%) 88.50 ( 11.72%) Stddev 8192 358.13 ( 0.00%) 169.99 ( 52.54%) Stddev 16384 43.99 ( 0.00%) 141.82 (-222.39%) Signed-off-by: Tony Jones <tonyj@suse.de> Fixes: `56974a6fcf` ("apparmor: add base infastructure for socket mediation") Signed-off-by: John Johansen <john.johansen@canonical.com> Signed-off-by: Sasha Levin <sashal@kernel.org>		2020-01-27 14:49:54 +01:00

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.
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.
