I'm afraid this is true. The pppd daemon fails to set the filter(s) with the message "Couldn't set pass-filter in kernel: Invalid argument". (It doesn't try to set the active-filter because it gives up after the first error.) For 3.15.x, you have to apply both of my patches to make it work. For 'net', presumably only the second patch ("fix creating PPP pass and active filters") is necessary because as you wrote, sk_chk_filter() can be called multiple times there. See also my comment in our bug tracker where the creation of the filter is compared between 3.14.x and 3.15.x (I'm afraid the description is in German): https://ssl.nettworks.org/bugs/browse/FFL-858?focusedCommentId=17289&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-17289 > Also it sounds like you've created a patch out of 3.15 tree, but marked it > as 'net-next'.
