Add per-instance tracing_on option, which will be useful with traceon/traceoff event trigger actions. For example, if we disable tracing_on by default and set traceon and traceoff on a pair of events, we can trace functions between the pair of events.

It seems that alloc_retstack_tasklist() can also take a lockless approach for scanning the tasklist, instead of using the big global tasklist_lock. For this we also kill another deprecated and rcu-unsafe tsk->thread_group user replacing it with for_each_process_thread(), maintaining semantics. Here tasklist_lock does not protect anything other than the list against concurrent fork/exit. And considering that the whole thing is capped by FTRACE_RETSTACK_ALLOC_SIZE (32), it should not be a problem to have a pontentially stale, yet stable, list. The task cannot go away either, so we don't risk racing with ftrace_graph_exit_task() which clears the retstack. The tsk->ret_stack management is not protected by tasklist_lock, being serialized with the corresponding publish/subscribe barriers against concurrent ftrace_push_return_trace(). In addition this plays nicer with cachelines by avoiding two atomic ops in the uncontended case. Link: https://lkml.kernel.org/r/20200907013326.9870-1-dave@stgolabs.netAcked-by:

It is advised to use module_name() macro instead of dereferencing mod->name directly. This makes sense for consistencys sake and also it prevents a hard dependency to CONFIG_MODULES.

Since the ftrace current setting may conflict with the new setting from bootconfig, add the --init option to initialize ftrace before setting for bconf2ftrace.sh.

Add a ftrace2bconf.sh under tools/bootconfig/scripts which generates a bootconfig file from the current ftrace settings. To read the ftrace settings, ftrace2bconf.sh requires the root privilege (or sudo). The ftrace2bconf.sh will output the bootconfig to stdout and error messages to stderr, so usually you'll run it as # ftrace2bconf.sh > ftrace.bconf Note that some ftrace configurations are not supported. For example, function-call/callgraph trace/notrace settings are not supported because the wildcard has been expanded and lost in the ftrace anymore.

Add a bconf2ftrace.sh under tools/bootconfig/scripts which generates a shell script to setup boot-time trace from bootconfig file for testing the bootconfig. bconf2ftrace.sh will take a bootconfig file (includes boot-time tracing) and convert it into a shell-script which is almost same as the boot-time tracer does. If --apply option is given, it also tries to apply those command to the running kernel, which requires the root privilege (or sudo). For example, if you just want to confirm the shell commands, save the output as below. # bconf2ftrace.sh ftrace.bconf > ftrace.sh Or, you can apply it directly. # bconf2ftrace.sh --apply ftrace.bconf Note that some boot-time tracing parameters under kernel.* are not able to set via tracefs nor procfs (e.g. tp_printk, traceoff_on_warning.), so those are ignored.

Since kprobe_event= cmdline option allows user to put kprobes on the functions in initmem, kprobe has to make such probes gone after boot. Currently the probes on the init functions in modules will be handled by module callback, but the kernel init text isn't handled. Without this, kprobes may access non-exist text area to disable or remove it.

For 64bit CONFIG_BASE_SMALL=0 systems PID_MAX_LIMIT is set by default to 4194304. During boot the kernel sets a new value based on number of CPUs but no lower than 32768. It is 1024 per CPU so with 128 CPUs the default becomes 131072 which needs six digits. This value can be increased during run time but must not exceed the initial upper limit. Systemd sometime after v241 sets it to the upper limit during boot. The result is that when the pid exceeds five digits, the trace output is a little hard to read because it is no longer properly padded (same like on big iron with 98+ CPUs). Increase the pid padding to seven digits. Link: https://lkml.kernel.org/r/20200904082331.dcdkrr3bkn3e4qlg@linutronix.deSigned-off-by:

Commit fc0ea795 ("ftrace: Add symbols for ftrace trampolines") missed to remove ops from new ftrace_ops_trampoline_list in ftrace_startup() if ftrace_hash_ipmodify_enable() fails there. It may lead to BUG if such ops come from a module which may be removed. Moreover, the trampoline itself is not freed in this case. Fix it by calling ftrace_trampoline_free() during the rollback.
