Subject: [PATCH] netlink: request all matches when requesting interface and address lists |
| 22 |
|
| 23 |
When requesting the a full list of interfaces and addresses for the machine |
| 24 |
avahi uses a wild card netlink search. This is done via a NLM_F_ROOT |
| 25 |
request. However we do not correctly request NLM_F_MATCH indicating |
| 26 |
we want all matches. This leads to the requests returning EINVAL on |
| 27 |
v2.6.38-rc1 and later kernels and to the daemon hanging during startup. |
| 28 |
|
| 29 |
Prior to v2.6.38-rc1 bugs in the kernel caused NLM_F_ROOT to incorrectly |
| 30 |
imply NLM_F_MATCH, see the commit below for details: |

netlink: test for all flags of the NLM_F_DUMP composite |
| 37 |
|
| 38 |
Add the missing NLM_F_MATCH. |
