Linux kernel CL error

[simonchen]

make[3]: *** No rule to make target 'net/netfilter/xt_TCPMSS.o', needed by 'net/netfilter/built-in.o'. Stop.

solved by https://lkml.org/lkml/2020/5/6/1301

===================================================

When compiling netfilter, there will be an error
"No rule to make target 'net/netfilter/xt_TCPMSS.o'",
because the xt_TCPMSS.c in the makefile is uppercase,
and the file name of the source file (xt_tcpmss.c) is lowercase.
Therefore, change the xt_TCPMSS.c name in the makefile to all lowercase.
===================================================

vim ./rt-n56u/trunk/linux-3.4.x/net/netfilter/Makefile

replace xt_TCPMSS.c with xt_tcpmss

Separately, CL error at ./trunk/user/miniupnpd/miniupnpd-2.x/netfilter/iptcrdr.c

trunk/user/miniupnpd/miniupnpd-2.x/netfilter/iptcrdr.c:990:28: error: invalid application of 'sizeof' to incomplete type 'struct xt_DSCP_info'
+ IPT_ALIGN(sizeof(struct xt_DSCP_info));

there is a line #include <linux/netfilter/xt_DSCP.h> that have declared the struct xt_DSCP_info,
not sure exactly why it couldn't be found then raised up 'invalid application of 'sizeof' to ...'

I've manually copy the sturct xt_DSCP_info in iptcrdr.c , CL is passed .

算了，不折腾了，让github自动编译
