netfilter: nf_log: fix error on write NONE to logger choice sysctl
It is hard to unbind nf-logger:
echo NONE > /proc/sys/net/netfilter/nf_log/0
bash: echo: write error: No such file or directory
sysctl -w net.netfilter.nf_log.0=NONE
sysctl: setting key "net.netfilter.nf_log.0": No such file or directory
net.netfilter.nf_log.0 = NONE
You need explicitly send '\0', for instance like:
echo -e "NONE\0" > /proc/sys/net/netfilter/nf_log/0
That seem to be strange, so fix it using proc_dostring.
Now it works fine:
modprobe nfnetlink_log
echo nfnetlink_log > /proc/sys/net/netfilter/nf_log/0
cat /proc/sys/net/netfilter/nf_log/0
nfnetlink_log
echo NONE > /proc/sys/net/netfilter/nf_log/0
cat /proc/sys/net/netfilter/nf_log/0
NONE
v2: add missed error check for proc_dostring
