commit c71bc6da6198a6d88df86094f1052bb581951d65 upstream. Currently, IPSec addresses are printed in hexadecimal format, which is not user-friendly. e.g. # cat /sys/kernel/debug/netdevsim/netdevsim0/ports/0/ipsec SA count=2 tx=20 sa[0] rx ipaddr=0x00000000 00000000 00000000 0100a8c0 sa[0] spi=0x00000101 proto=0x32 salt=0x0adecc3a crypt=1 sa[0] key=0x3167608a ca4f1397 43565909 941fa627 sa[1] tx ipaddr=0x00000000 00000000 00000000 00000000 sa[1] spi=0x00000100 proto=0x32 salt=0x0adecc3a crypt=1 sa[1] key=0x3167608a ca4f1397 43565909 941fa627 This patch updates the code to print the IPSec address in a human-readable format for easier debug. e.g. # cat /sys/kernel/debug/netdevsim/netdevsim0/ports/0/ipsec SA count=4 tx=40 sa[0] tx ipaddr=0.0.0.0 sa[0] spi=0x00000100 proto=0x32 salt=0x0adecc3a crypt=1 sa[0] key=0x3167608a ca4f1397 43565909 941fa627 sa[1] rx ipaddr=192.168.0.1 sa[1] spi=0x00000101 proto=0x32 salt=0x0adecc3a crypt=1 sa[1] key=0x3167608a ca4f1397 43565909 941fa627 sa[2] tx ipaddr=:: sa[2] spi=0x00000100 proto=0x32 salt=0x0adecc3a crypt=1 sa[2] key=0x3167608a ca4f1397 43565909 941fa627 sa[3] rx ipaddr=2000::1 sa[3] spi=0x00000101 proto=0x32 salt=0x0adecc3a crypt=1 sa[3] key=0x3167608a ca4f1397 43565909 941fa627 Reviewed-by: Simon Horman <horms@kernel.org> Signed-off-by: Hangbin Liu <liuhangbin@gmail.com> Link: https://patch.msgid.link/20241010040027.21440-2-liuhangbin@gmail.com Signed-off-by: Jakub Kicinski <kuba@kernel.org> Signed-off-by: Harshit Mogalapalli <harshit.m.mogalapalli@oracle.com> Signed-off-by: Greg Kroah-Hartman <gregkh@linuxfoundation.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 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.
