Hi, netfilter experts,
A customer wants to increase XT_EXTENSION_MAXNAMELEN to at least 31 (1
for '\0'), so I just increase it to 32. Do you have any comments or
objections for the following patch?
The vmlinux size increases by 768 bytes with my allyesconfig:
% size vmlinux
text data bss dec hex filename
15158877 3942208 11812864 30913949 1d7b59d vmlinux
% size vmlinux.AFTER
text data bss dec hex filename
15158877 3942976 11812864 30914717 1d7b89d vmlinux.AFTER
I know probably the user-space part needs to update too, here is just
the kernel part patch for you to review. And I only did compile test.
Thanks!
