From 7598b2b918835ab71e48bd7617812bde3a2537a7 Mon Sep 17 00:00:00 2001 From: Jerome Marchand Date: Thu, 11 Jun 2020 14:56:36 +0200 Subject: [PATCH 4/6] RHEL-8: aarch64: fixes statsnoop and opensnoop On aarch64 the open syscall has been dropped. Only openat remains, wich is called by libc open() function. The state of *stat* syscalls, is a mess. They are several generations of the system calls, and not all arches provides all of them. For instance, new(l)stat are missing from aarch64. The only way I can think of fixing thess is RHEL-8 only arch specific patches. --- tools/opensnoop.bt | 2 -- tools/statsnoop.bt | 8 ++------ 2 files changed, 2 insertions(+), 8 deletions(-) diff --git a/tools/opensnoop.bt b/tools/opensnoop.bt index a7de8026..d99db93e 100755 --- a/tools/opensnoop.bt +++ b/tools/opensnoop.bt @@ -21,13 +21,11 @@ BEGIN printf("%-6s %-16s %4s %3s %s\n", "PID", "COMM", "FD", "ERR", "PATH"); } -tracepoint:syscalls:sys_enter_open, tracepoint:syscalls:sys_enter_openat { @filename[tid] = args->filename; } -tracepoint:syscalls:sys_exit_open, tracepoint:syscalls:sys_exit_openat /@filename[tid]/ { diff --git a/tools/statsnoop.bt b/tools/statsnoop.bt index b2d529e2..f612ea94 100755 --- a/tools/statsnoop.bt +++ b/tools/statsnoop.bt @@ -30,17 +30,13 @@ tracepoint:syscalls:sys_enter_statfs @filename[tid] = args->pathname; } -tracepoint:syscalls:sys_enter_statx, -tracepoint:syscalls:sys_enter_newstat, -tracepoint:syscalls:sys_enter_newlstat +tracepoint:syscalls:sys_enter_statx { @filename[tid] = args->filename; } tracepoint:syscalls:sys_exit_statfs, -tracepoint:syscalls:sys_exit_statx, -tracepoint:syscalls:sys_exit_newstat, -tracepoint:syscalls:sys_exit_newlstat +tracepoint:syscalls:sys_exit_statx /@filename[tid]/ { $ret = args->ret; -- 2.35.3
