xfrm: make xfrm modes builtin

2019-04-08T07:15:17Z

after previous changes, xfrm_mode contains no function pointers anymore and all modules defining such struct contain no code except an init/exit functions to register the xfrm_mode struct with the xfrm core. Just place the xfrm modes core and remove the modules, the run-time xfrm_mode register/unregister functionality is removed. Before: text data bss dec filename 7523 200 2364 10087 net/xfrm/xfrm_input.o 40003 628 440 41071 net/xfrm/xfrm_state.o 15730338 6937080 4046908 26714326 vmlinux 7389 200 2364 9953 net/xfrm/xfrm_input.o 40574 656 440 41670 net/xfrm/xfrm_state.o 15730084 6937068 4046908 26714060 vmlinux The xfrm*_mode_{transport,tunnel,beet} modules are gone. v2: replace CONFIG_INET6_XFRM_MODE_* IS_ENABLED guards with CONFIG_IPV6 ones rather than removing them.

netfilter: nat: merge nf_nat_ipv4,6 into nat core

2019-02-27T09:49:55Z

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.

selftests: explicitly require kernel features needed by udpgro tests

2018-11-22T19:35:28Z

commit 3327a9c46352f1 ("selftests: add functionals test for UDP GRO") make use of ipv6 NAT, but such a feature is not currently implied by selftests. Since the 'ip[6]tables' commands may actually create nft rules, depending on the specific user-space version, let's pull both NF and NFT nat modules plus the needed deps.

selftests: create test-specific kconfig fragments

2016-02-25T16:47:52Z

Create the config file in each directory of testcase which need more kernel configuration than the default defconfig. User could use these configs with merge_config.sh script: Enable config for specific testcase: (export ARCH=xxx #for cross compiling) ./scripts/kconfig/merge_config.sh .config \ tools/testing/selftests/xxx/config Enable configs for all testcases: (export ARCH=xxx #for cross compiling) ./scripts/kconfig/merge_config.sh .config \ tools/testing/selftests/*/config Signed-off-by: Bamvor Jian Zhang Reviewed-by: Shuah Khan Signed-off-by: Shuah Khan
