From: "Steven Rostedt (VMware)" <rostedt@xxxxxxxxxxx> The assignment of path was suppose to copy the dir variable that is returned from tracefs_tracing_dir(), but instead the path copied itself. This broke the communication between host and guest as well as networking. Fixes: b8498696e0 ("trace-cmd: Use tracefs_tracing_dir() instead of tracefs_find_tracing_dir()") Signed-off-by: Steven Rostedt (VMware) <rostedt@xxxxxxxxxxx> --- tracecmd/trace-record.c | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) diff --git a/tracecmd/trace-record.c b/tracecmd/trace-record.c index a1c4e919..b05eef35 100644 --- a/tracecmd/trace-record.c +++ b/tracecmd/trace-record.c @@ -3341,7 +3341,7 @@ static int create_recorder(struct buffer_instance *instance, int cpu, const char *dir = tracefs_tracing_dir(); if (dir) - path = strdup(path); + path = strdup(dir); } if (!path) die("can't get the tracing directory"); -- 2.25.4
