Followup-For: Bug #413428
I extracted the attached patches from the full Ubuntu patch referenced
by Andreas Henriksson in an earlier report.
The attached patch just adds modprobing of net-pf-10 (alias ipv6) to
basically all "up" methods. This allows users to blacklist ipv6 by
adding
alias net-pf-10 none
to their modprobe/modutils configuration.
alias net-pf-10 ipv6
(the default TTBOMK) enables ipv6.
This should fix #413428 sufficiently well, especially when the above
note is taken into some place of the documentation.
regards,
Sven
PS: If I find the time, I will also add documentation of this tweak
somewhere.
Suggested Changelog entry:
Modprobe net-pf-10 before configuring interfaces (inspired by Ubuntu
patch from https://patches.ubuntu.com/i/ifupdown and comments by Andreas
Henriksson). Patch by Sven Mueller <[email protected]> (Closes #413428)
Suggested note for README or some other suitable doc:
ifup now runs modprobe on net-pf-10 before bringing up an interface.
This enables IPv6. If you don't want IPv6 support, add the following
line to your modprobe/modutils configuration, such as
/etc/modutils/aliases:
alias net-pf-10 none
