Here we assigned it a default log per its arguments, and simplify the sanity check so that it can be consistent with the document. Please note that i also removed following addition stuff, since we have added this prefix if needed during parsing the FILENAME in parse_options_prefix(). if (strncmp(monitor.log, "./", 2) != 0) fix_filename(prefix, (const char **)&monitor.log); Signed-off-by: Li Zhijian --- V2: exchange order of previous patch1 and patch2 # Alison a few commit log updated Signed-off-by: Li Zhijian --- cxl/monitor.c | 38 ++++++++++++++++++++------------------ 1 file changed, 20 insertions(+), 18 deletions(-) diff --git a/cxl/monitor.c b/cxl/monitor.c index e3469b9a4792..c6df2bad3c53 100644 --- a/cxl/monitor.c +++ b/cxl/monitor.c @@ -164,6 +164,7 @@ int cmd_monitor(int argc, const char **argv, struct cxl_ctx *ctx) }; const char *prefix ="./"; int rc = 0, i; + const char *log; argc = parse_options_prefix(argc, argv, prefix, options, u, 0); for (i = 0; i < argc; i++) @@ -171,32 +172,33 @@ int cmd_monitor(int argc, const char **argv, struct cxl_ctx *ctx) if (argc) usage_with_options(u, options); + // sanity check + if (monitor.daemon && monitor.log && !strncmp(monitor.log, "./", 2)) { + error("standard or relative path for will not work for daemon mode\n"); + return -EINVAL; + } + log_init(&monitor.ctx, "cxl/monitor", "CXL_MONITOR_LOG"); - monitor.ctx.log_fn = log_standard; + if (monitor.log) + log = monitor.log; + else + log = monitor.daemon ? default_log : "./standard"; if (monitor.verbose) monitor.ctx.log_priority = LOG_DEBUG; else monitor.ctx.log_priority = LOG_INFO; - if (monitor.log) { - if (strncmp(monitor.log, "./", 2) != 0) - fix_filename(prefix, (const char **)&monitor.log); - if (strncmp(monitor.log, "./standard", 10) == 0 && !monitor.daemon) { - monitor.ctx.log_fn = log_standard; - } else { - const char *log = monitor.log; - - if (!monitor.log) - log = default_log; - monitor.log_file = fopen(log, "a+"); - if (!monitor.log_file) { - rc = -errno; - error("open %s failed: %d\n", monitor.log, rc); - goto out; - } - monitor.ctx.log_fn = log_file; + if (strncmp(log, "./standard", 10) == 0) + monitor.ctx.log_fn = log_standard; + else { + monitor.log_file = fopen(log, "a+"); + if (!monitor.log_file) { + rc = -errno; + error("open %s failed: %d\n", log, rc); + goto out; } + monitor.ctx.log_fn = log_file; } if (monitor.daemon) {
