From 3917fa32dce8c887d0a87d0d2f4490f1b89b51d0 Mon Sep 17 00:00:00 2001 From: Peter Korsgaard Date: Sun, 6 Jan 2013 00:07:17 +0100 Subject: [PATCH] dmesg: handle multi-char log levels Since Linux 3.5 (7ff9554bb5: printk: convert byte-buffer to variable-length record buffer), klog buffer can now contain log lines with multi-char loglevel indicators (<[0-9]+>) - So we can no longer just skip 3 bytes. Instead skip past the terminating '>' like util-linux does. function old new delta dmesg_main 266 280 +13 ------------------------------------------------------------------------------ (add/remove: 0/0 grow/shrink: 1/0 up/down: 13/0) Total: 13 bytes Signed-off-by: Peter Korsgaard Signed-off-by: Mike Frysinger --- util-linux/dmesg.c | 13 ++++++------- 1 file changed, 6 insertions(+), 7 deletions(-) diff --git a/util-linux/dmesg.c b/util-linux/dmesg.c index 6505da54b..81ba1c9d1 100644 --- a/util-linux/dmesg.c +++ b/util-linux/dmesg.c @@ -59,16 +59,15 @@ int dmesg_main(int argc UNUSED_PARAM, char **argv) int last = '\n'; int in = 0; - /* Skip <#> at the start of lines */ + /* Skip <[0-9]+> at the start of lines */ while (1) { if (last == '\n' && buf[in] == '<') { - in += 3; - if (in >= len) - break; + while (buf[in++] != '>' && in < len) + ; + } else { + last = buf[in++]; + putchar(last); } - last = buf[in]; - putchar(last); - in++; if (in >= len) break; } -- 2.25.1
