Tunnel change fails if a tunnel name is not specified while using 'ip -6 tunnel change'. However, no warning message is printed and no error code is returned. $ ip -6 tunnel add ip6tnl1 mode ip6gre local fd::1 remote fd::2 tos inherit ttl 127 encaplimit none dev dummy0 $ ip -6 tunnel change dev dummy0 local 2001🔢:1 remote 2001🔢:2 $ ip -6 tunnel show ip6tnl1 ip6tnl1: gre/ipv6 remote fd::2 local fd::1 dev dummy0 encaplimit none hoplimit 127 tclass inherit flowlabel 0x00000 (flowinfo 0x00000000) This commit checks if tunnel interface name is equal to an empty string: in this case, it prints a warning message to the user. It intentionally avoids to return an error to not break existing script setup. This is the output after this commit: $ ip -6 tunnel add ip6tnl1 mode ip6gre local fd::1 remote fd::2 tos inherit ttl 127 encaplimit none dev dummy0 $ ip -6 tunnel change dev dummy0 local 2001🔢:1 remote 2001🔢:2 Tunnel interface name not specified $ ip -6 tunnel show ip6tnl1 ip6tnl1: gre/ipv6 remote fd::2 local fd::1 dev dummy0 encaplimit none hoplimit 127 tclass inherit flowlabel 0x00000 (flowinfo 0x00000000) Reviewed-by: Matteo Croce <mcroce@redhat.com> Signed-off-by: Andrea Claudi <aclaudi@redhat.com> Signed-off-by: Stephen Hemminger <stephen@networkplumber.org> |

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.
