 Posted: Mon Jun 06, 2016 11:24 am Post subject: [kernel] since 4.6.0 igmp_max_memberships is 0 (solved) |
 |
|
Since the update of the 4.6.0 kernel, I can not join a multicast group.
Could you pass the value of
| Code: | | less /proc/sys/net/ipv4/igmp_max_memberships |
I can compare with my value is 0
with kernel 4.5.3 this value is 20
my bug report was kicked but on kernel newbie i can read
| Code: | | IGMP: Add namespaces support for the following sysctls: igmp_llm_reports commit, igmp_max_memberships commit, igmp_max_msf commit, igmp_qrv commit |
so something has changed, but i can't find where.
Thanks

| I've commented on the bug. I can reproduce this issue. I think the bugreport should be reopened... |

| Code: | $ uname -r
4.6.1-gentoo
$ cat /proc/sys/net/ipv4/igmp_max_memberships
20 |
Which bug? This bug?
I'm having a problem with both 4.6.0 and 4.6.1 and rsync which appears to be ipv4 related. |

Thank you for providing the link. A search for igmp_max_memberships results in Zarro Boogs found.
OP may want to try gentoo-sources-4.6.1. |

you need to search for | Code: | | ALL igmp_max_memberships |
to find closed bugs as well  |

Yep,
you must now have
| Code: | | CONFIG_IP_MULTICAST to true |
to join a multicast group. First time i activate this option. This "bug" is solved for me. Thanks for help. |
