Public bug reported:
The upstream linux-stable release v4.14.217 contains the following
commit (also attached here):
5440233ac430 net: use skb_list_del_init() to remove from RX sublists
... which introduces skb_mark_not_on_list() to linux v4.14. This will
cause a wireguard-linux-compat build failure for v4.14-based kernels, as
well as Ubuntu Bionic (v4.15) which takes ports of the 4.14-series patch
sets:
<<DKMSDIR>>/build/wireguard/1.0.20201112/build/compat/compat.h:830:20:
error:
redefinition of 'skb_mark_not_on_list'
static inline void skb_mark_not_on_list(struct sk_buff *skb)
In file included from
<<DKMSDIR>>/build/wireguard/1.0.20201112/build/compat/compat.h:789:0,
./include/linux/skbuff.h:1346:20: note: previous definition of
'skb_mark_not_on_list' was here
static inline void skb_mark_not_on_list(struct sk_buff *skb)
For Bionic, the situation is complicated since Bionic's v4.15
KERNEL_VERSION 'SUBLEVEL' does not encode the SUBLEVEL number (217) from
the 4.14 series, so a simple switch on SUBLEVEL will not be sufficient
for Bionic.
We're holding out the port of the noted stable commit from Bionic,
pending resolution of this.
