Three ways to view Linux kernel module dependencies __linux

Take Ip_tables.ko-dependent X_tables.ko as an example:

1, lsmod command

$ lsmod 
Module                  Size  Used by
iptable_filter          1790  1 
ip_tables               7706  1 iptable_ Filter
x_tables                8327  1 ip_tables
vmhgfs                 41755  0 
vsock                  30939  

2. View MODULES.DEP Files

$ cat/lib/modules/2.6.32-5-686/modules.dep ... 
.
Kernel/net/ipv4/netfilter/ip_tables.ko:kernel/net/netfilter/x_tables.ko
Kernel/net/ipv4/netfilter/iptable_ Filter.ko:kernel/net/ipv4/netfilter/ip_tables.ko Kernel/net/netfilter/x_tables.ko
Kernel/net/ipv4/netfilter /iptable_mangle.ko:kernel/net/ipv4/netfilter/ip_tables.ko Kernel/net/netfilter/x_tables.ko
kernel/net/ipv4/ Netfilter/iptable_nat.ko:kernel/net/ipv4/netfilter/ip_tables.ko Kernel/net/ipv4/netfilter/nf_nat.ko kernel/net/ Netfilter/x_tables.ko Kernel/net/ipv4/netfilter/nf_conntrack_ipv4.ko Kernel/net/netfilter/nf_conntrack.ko kernel/ Net/ipv4/netfilter/nf_defrag_ipv4.ko .....

3, Modinfo command

$/sbin/modinfo ip_tables 
filename:/lib/modules/2.6.32-5-686/kernel/net/ipv4/netfilter/ip_tables.ko
Description:ipv4 packet filter
author:netfilter Core team 
LICENSE:GPL
depends:x_t Ables
vermagic:2.6.32-5-686 SMP mod_unload modversions 686

This command reads the MODULES.DEP file to obtain a dependency
