Subject: [PATCH] arptables: Fix parsing of inverted 'arp operation' match
|
||
|
|
|
||
|
|
The wrong bit was set in 'invflags', probably due to copy'n'paste from
|
||
|
|
the previous case.
|
||
|
|
|
||
|
|
Fixes: 84909d171585d ("xtables: bootstrap ARP compatibility layer for nftables")
|
||
|
|
Signed-off-by: Phil Sutter <phil@nwl.cc>

||
|
|
(cherry picked from commit 092e4b022152addc94524e2ba0cb608dac1a3a08)
