Hi,
I admittedly didn't fully analyze the cause, but on my system a call to:
# insmod /lib/module/$(uname -r)/kernel/net/netfilter/nf_conntrack_ftp.ko
fails with -EEXIST (due to a previous call to 'nfct add helper ftp inet
tcp'). A call to:
# modprobe nf_conntrack_ftp
though returns 0 even though module loading fails. Is there a bug in
modprobe error status handling?
Read the man page : https://linux.die.net/man/8/modprobe
In the man page I see:
Normally, modprobe will succeed (and do nothing) if told to
insert a module which is already present or to remove a module which
isn't present.
