Re: [BUG] 4.9 - kernel oops when pptp connection is established and the kernel doesn't have pptp modules compiled

Sorry, after further inspection, it seems like the choice of skb_header_pointer is wrong and skb isn't always populated. It seems like the code has suffered from bitrot since all the surrounding code is actually fixed. This fixes it as well: diff --git a/net/core/flow_dissector.c b/net/core/flow_d

[BUG] 4.9 - kernel oops when pptp connection is established and the kernel doesn't have pptp modules compiled

Hi, Been fighting with "crash" to get it to help me to analyze my crash dumps... This is the output from vmcore-dmesg. This is 100% reproducible... Config that lets the connection trough but crashes the kernel: # CONFIG_NF_CONNTRACK_PPTP is not set # CONFIG_NF_NAT_PPTP is not set CONFIG_PPTP=y
