![]() Prior to this commit, running 'ss' on a kernel older than v5.9
bumps an error message:
RTNETLINK answers: Invalid argument
When asked to dump protocol number > 255 - that is: MPTCP - 'ss'
adds an INET_DIAG_REQ_PROTOCOL attribute, unsupported by the older
kernel.
Avoid the warning ignoring filter issues when INET_DIAG_REQ_PROTOCOL
is used.
Additionally older kernel end-up invoking tcpdiag_send(), which
in turn will try to dump DCCP socks. Bail early in such function,
as the kernel does not implement an MPTCPDIAG_GET request.

This is a set of utilities for Linux networking. Information: https://wiki.linuxfoundation.org/networking/iproute2 Download: http://www.kernel.org/pub/linux/utils/net/iproute2/ Stable version repository: git://git.kernel.org/pub/scm/network/iproute2/iproute2.git Development repository: git://git.kernel.org/pub/scm/network/iproute2/iproute2-next.git How to compile this. -------------------- 1. libdbm arpd needs to have the berkeleydb development libraries. For Debian users this is the package with a name like libdbX.X-dev. DBM_INCLUDE points to the directory with db_185.h which is the include file used by arpd to get to the old format Berkeley database routines. Often this is in the db-devel package. 2. make The makefile will automatically build a config.mk file which contains definitions of libraries that may or may not be available on the system such as: ATM, ELF, MNL, and SELINUX. 3. To make documentation, cd to doc/ directory , then look at start of Makefile and set correct values for PAGESIZE=a4 , ie: a4 , letter ... (string) PAGESPERPAGE=2 , ie: 1 , 2 ... (numeric) and make there. It assumes, that latex, dvips and psnup are in your path. 4. This package includes matching sanitized kernel headers because the build environment may not have up to date versions. See Makefile if you have special requirements and need to point at different kernel include files. Stephen Hemminger stephen@networkplumber.org Alexey Kuznetsov kuznet@ms2.inr.ac.ru
