Describe the bug
Logging prevents rules from being applied for some kernels
symptom: toaster: “Error applying iptables rules”
Pixel 3, Android 12: works
Pixel 6, Android 12: does not work
It seems all Androids have NFLOG but newer Androids do not have LOG
the LOG target is not available, which can be checked:
zcat /proc/config.gz | grep CONFIG_NETFILTER_XT_TARGET_LOG
# CONFIG_NETFILTER_XT_TARGET_LOG is not set
zcat /proc/config.gz | grep CONFIG_NETFILTER_XT_TARGET_NFLOG
CONFIG_NETFILTER_XT_TARGET_NFLOG=y
iptables --new-chain X
iptables --append X --jump NFLOG
# OK
iptables --append X --jump LOG
iptables v1.8.7 (legacy): Couldn't find target `LOG'
Try `iptables -h' or 'iptables --help' for more information.
IMPACT:
AFWall+ Log function cannot be used on devices that do not have the iptables LOG target
Firewall Logs
N/A
version: 3.6dev+
Smartphone (please complete the following information):
Pixel 3/6
Additional context
it is unclear how NFLOG can be directed to logcat on Android
