Mon, 15 Jan 2024 20:55:14 +0000

selftest: bpf: Test bpf_sk_assign_tcp_reqsk().This commit adds a sample selftest to demonstrate how we can usebpf_sk_assign_tcp_reqsk() as the backend of SYN Proxy.The test creates IPv4/IPv6 x TCP connections and transfer messagesover them on lo with BPF tc prog attached.The tc prog will process SYN and returns SYN+ACK with the followingISN and TS. In a real use case, this part will be done by otherhosts. MSB LSB ISN: | 31 ... 8 | 7 6 | 5 | 4 | 3 2 1 0 | | Hash_1 | MSS | ECN | SACK | WScale | TS: | 31 ... 8 | 7 ... 0 | | Random | Hash_2 | WScale in SYN is reused in SYN+ACK.The client returns ACK, and tc prog will recalculate ISN and TSfrom ACK and validate SYN Cookie.If it's valid, the prog calls kfunc to allocate a reqsk for skb andconfigure the reqsk based on the argument created from SYN Cookie.Later, the reqsk will be processed in cookie_v[46]_check() to createa connection.Signed-off-by: Kuniyuki Iwashima Link: https://lore.kernel.org/r/20240115205514.68364-7-kuniyu@amazon.comSigned-off-by: Martin KaFai Lau Signed-off-by: Alexei Starovoitov List of files: /linux-6.15/tools/testing/selftests/bpf/config

selftests/bpf: Add tests for filesystem kfuncsAdd selftests for two new filesystem kfuncs: 1. bpf_get_file_xattr 2. bpf_get_fsverity_digestThese tests simply make sure the two kfuncs work. Another selftest will beadded to demonstrate how to use these kfuncs to verify file signature.CONFIG_FS_VERITY is added to selftests config. However, this is notsufficient to guarantee bpf_get_fsverity_digest works. This is becausefsverity need to be enabled at file system level (for example, with tune2fson ext4).

3d272c2f - selftests/bpf: Add missing selftests kconfig options

Fri, 02 Jun 2023 14:01:08 +0000

selftests/bpf: Add missing selftests kconfig optionsOur selftests of course rely on the kernel being built withCONFIG_DEBUG_INFO_BTF=y, though this (nor its dependencies ofCONFIG_DEBUG_INFO=y and CONFIG_DEBUG_INFO_DWARF4=y) are not specified.This causes the wrong kernel to be built, and selftests to similarlyfail to build.Additionally, in the BPF selftests kconfig file,CONFIG_NF_CONNTRACK_MARK=y is specified, so that the 'u_int32_t mark'field will be present in the definition of struct nf_conn. While adependency of CONFIG_NF_CONNTRACK_MARK=y, CONFIG_NETFILTER_ADVANCED=y,should be enabled by default, I've run into instances ofCONFIG_NF_CONNTRACK_MARK not being set because CONFIG_NETFILTER_ADVANCEDisn't set, and have to manually enable them with make menuconfig.Let's add these missing kconfig options to the file so that thenecessary dependencies are in place to build vmlinux. Otherwise, we'llget errors like this when we try to compile selftests and generatevmlinux.h:$ cd /path/to/bpf-next$ make mrproper; make defconfig$ cat tools/testing/selftests/config >> .config$ make -j...$ cd tools/testing/selftests/bpf$ make clean$ make -j...
