samples: bpf: Fix syscall_tp openat argument

2023-10-23T16:58:15+00:00

This modification doesn't change behaviour of the syscall_tp But such code is often used as a reference so it should be correct anyway Signed-off-by: Denys Zagorui Signed-off-by: Andrii Nakryiko Link: https://lore.kernel.org/bpf/20231019113521.4103825-1-dzagorui@cisco.com

samples/bpf: Add openat2() enter/exit tracepoint to syscall_tp sample

2023-02-09T00:50:42+00:00

Commit fe3300897cbf("samples: bpf: fix syscall_tp due to unused syscall") added openat() syscall tracepoints. This patch adds support for openat2() as well. Signed-off-by: Rong Tao Signed-off-by: Andrii Nakryiko Link: https://lore.kernel.org/bpf/tencent_9381CB1A158ED7ADD12C4406034E21A3AC07@qq.com

samples: bpf: Refactor tracepoint tracing programs with libbpf

2020-08-25T03:59:35+00:00

For the problem of increasing fragmentation of the bpf loader programs, instead of using bpf_loader.o, which is used in samples/bpf, this commit refactors the existing tracepoint tracing programs with libbbpf bpf loader. - Adding a tracepoint event and attaching a bpf program to it was done through bpf_program_attach(). - Instead of using the existing BPF MAP definition, MAP definition has been refactored with the new BTF-defined MAP format.

samples/bpf: Use consistent include paths for libbpf

2020-01-21T00:37:45+00:00

Fix all files in samples/bpf to include libbpf header files with the bpf/ prefix, to be consistent with external users of the library. Also ensure that all includes of exported libbpf header files (those that are exported on 'make install' of the library) use bracketed includes instead of quoted. To make sure no new files are introduced that doesn't include the bpf/ prefix in its include, remove tools/lib/bpf from the include path entirely, and use tools/lib instead.

samples: bpf: fix syscall_tp due to unused syscall

2019-12-11T23:28:06+00:00

Currently, open() is called from the user program and it calls the syscall 'sys_openat', not the 'sys_open'. This leads to an error of the program of user side, due to the fact that the counter maps are zero since no function such 'sys_open' is called. This commit adds the kernel bpf program which are attached to the tracepoint 'sys_enter_openat' and 'sys_enter_openat'.
