before: text data bss dec hex filename 16566 1576 4136 22278 5706 nf_nat.ko 3598 844 0 4442 115a nf_nat_ipv6.ko 3187 844 0 4031 fbf nf_nat_ipv4.ko after: text data bss dec hex filename 22948 1612 4136 28696 7018 nf_nat.ko ... with ipv4/v6 nat now provided directly via nf_nat.ko. Also changes: ret = nf_nat_ipv4_fn(priv, skb, state); if (ret != NF_DROP && ret != NF_STOLEN && into if (ret != NF_ACCEPT) return ret; everywhere. The nat hooks never should return anything other than ACCEPT or DROP (and the latter only in rare error cases). The original code uses multi-line ANDing including assignment-in-if: if (ret != NF_DROP && ret != NF_STOLEN && !(IPCB(skb)->flags & IPSKB_XFRM_TRANSFORMED) && (ct = nf_ct_get(skb, &ctinfo)) != NULL) { I removed this while moving, breaking those in separate conditionals and moving the assignments into extra lines. checkpatch still generates some warnings: 1. Overly long lines (of moved code). Breaking them is even more ugly. so I kept this as-is. 2. use of extern function declarations in a .c file. This is necessary evil, we must call nf_nat_l3proto_register() from the nat core now. All l3proto related functions are removed later in this series, those prototypes are then removed as well. v2: keep empty nf_nat_ipv6_csum_update stub for CONFIG_IPV6=n case. v3: remove IS_ENABLED(NF_NAT_IPV4/6) tests, NF_NAT_IPVx toggles are removed here. v4: also get rid of the assignments in conditionals.

Linux kernel ============ There are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. Please read Documentation/admin-guide/README.rst first. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. The formatted documentation can also be read online at: https://www.kernel.org/doc/html/latest/ There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
