2023-02-02af_xdp: fix default xdp program unload failYulong Pei1-20/+45
Change to get ad->linux_ifindex in af_xdp_create_if() instead of in af_xdp_load_program(), previous if did not load custom XDP program, ad->linux_ifindex will be none, but bpf_xdp_detach() need it, so default xdp program will be not unloaded when delete af_xdp interface.

2023-01-24af_xdp: fix xdp socket create failChen Yahui1-2/+18
In libbpf code, xsk_socket__create will call xsk_link_lookup to get the xdp_sock bpf prog. But xsk_link_lookup can't get any bpf prog. This will cause Libbpf not to insert the fd into xsks_map and return ERROR. The solution to this problem is to insert fd into xsks_map ourselves instead of libbpf.

2023-01-13af_xdp: update af_xdp driver plugin to depend on libxdpYulong Pei3-26/+41
AF_XDP support is deprecated in libbpf since v0.7.0 [1], the libxdp library now provides the functionality which once was in libbpf, this commit updates af_xdp plugin to depend on libxdp, libbpf still remains a dependency even if libxdp is present, as it need use libbpf APIs for program loading. libxdp is distributed within xdp-tool [2], xdp-tools package also include libbpf in it as dependency, so here installed libxdp v1.2.9 and libbpf v0.8.0, both from xdp-tool-1.2.9 package. More information about libxdp compatibility can be found in the libxdp README [3]. In libbpf v0.8.0, The bpf_prog_load function was deprecated and changed to bpf_object__open_file and bpf_object__next_program and bpf_object__load, The bpf_get_link_xdp_id and bpf_set_link_xdp_fd functions were deprecated and changed to bpf_xdp_attach and bpf_xdp_detach, The bpf_object__unload function was deprecated and changed to bpf_object__close.

2022-09-28af_xdp: change RLIMIT_MEMLOCK before load bpf programChen Yahui1-0/+7
default RLIMIT_MEMLOCK is 64. if we use multi af_xdp interfaces or load complex bpf program, libbpf will return permission error. root cause is default 64 is not large enough.

2022-02-16af_xdp: change flag passed to bpf_set_link_xdp_fdDastin Wilski1-4/+1
Originally XDP_FLAGS_REPLACE was passed to the function. For kernels not defining this macro (for example 5.4) in if_link.h vpp sets it to 0. If kernel has this macro problem appears, replace flag requires specifying the program to be replaced. bpf_set_link_xdp_fd wraps around __bpf_set_link_xdp_fd_replace and passes 0 as old_fd, it leads to an error while assessing for replacement (if 0 is passed there is no assessing for replacement). To address this issue no flag is passed to the function, only 0. Type: improvement Signed-off-by: Dastin Wilski <dastin.wilski@gmail.com> Change-Id: I3689ce7eb8c71c699f0e589111929979c2bbe213

2021-05-21af_xdp: workaround kernel race between poll() and sendmsg()Benoît Ganne10-86/+213
Prior to Linux 5.6 there is a race condition between poll() and sendmsg() in the kernel. This patch protects the syscalls with a lock to prevent it, unless the NO_SYSCALL_LOCK flag is set at create time. See https://lore.kernel.org/bpf/BYAPR11MB365382C5DB1E5FCC53242609C1549@BYAPR11MB3653.namprd11.prod.outlook.com/ Type: fix Change-Id: Ie7d4f5cb41f697b11a09b6046e54d190430d76df Signed-off-by: Benoît Ganne <bganne@cisco.com>
2021-05-01vlib: refactor trajectory trace debug featureBenoît Ganne2-12/+18
trajectory trace has been broken for a while because we used to save the buffer trajectory in a vector pointed to in opaque2. This does not work well when opaque2 is copied (eg. because of a clone) as 2 buffers end up sharing the same vector. This dedicates a full cacheline in the buffer metadata instead when trajectory is compiled in. No dynamic allocation, no sharing, no tears.
