| 2023-08-15 | perf bpf examples: With no BPF events remove examples | Ian Rogers | 1 | -33/+0 | |
| The examples were used to give demonstrations of BPF events but such functionality is now subsumed by using --filter with 'perf record' or the direct use of BPF skeletons.

| 2018-08-08 | perf bpf: Add 'syscall_enter' probe helper for syscall enter tracepoints | Arnaldo Carvalho de Melo | 1 | -0/+33 | |
| Allowing one to hook into the syscalls:sys_enter_NAME tracepoints, an example is provided that hooks into the 'openat' syscall. Using it with the probe:vfs_getname probe into getname_flags to get the filename args as it is copied from userspace: # perf probe -l probe:vfs_getname (on getname_flags:73@acme/git/linux/fs/namei.c with pathname) # perf trace -e probe:*getname,tools/perf/examples/bpf/sys_enter_openat.c cat /etc/passwd > /dev/null 0.000 probe:vfs_getname:(ffffffffbd2a8983) pathname="/etc/ld.so.preload" 0.022 syscalls:sys_enter_openat:dfd: CWD, filename: 0xafbe8da8, flags: CLOEXEC 0.027 probe:vfs_getname:(ffffffffbd2a8983) pathname="/etc/ld.so.cache" 0.054 syscalls:sys_enter_openat:dfd: CWD, filename: 0xafdf0ce0, flags: CLOEXEC 0.057 probe:vfs_getname:(ffffffffbd2a8983) pathname="/lib64/libc.so.6" 0.316 probe:vfs_getname:(ffffffffbd2a8983) pathname="/usr/lib/locale/locale-archive" 0.375 syscalls:sys_enter_openat:dfd: CWD, filename: 0xe2b2b0b4 0.379 probe:vfs_getname:(ffffffffbd2a8983) pathname="/etc/passwd" # Cc: Adrian Hunter <[email protected]> Cc: David Ahern <[email protected]> Cc: Jiri Olsa <[email protected]> Cc: Namhyung Kim <[email protected]> Cc: Wang Nan <[email protected]> Link: https://lkml.kernel.org/n/[email protected] Signed-off-by: Arnaldo Carvalho de Melo <[email protected]> | |||||
