kl-kdmesg¶
Kernel log
Canonical: kernlens-kdmesg
Category: kernel metadata
Synopsis: kl-kdmesg [-h] [-T]
Prints the ring buffer (dmesg) by walking the prb/printk_info records directly, which works even when dmesg is restricted for unprivileged users.
Options¶
| Option | Argument | Meaning |
|---|---|---|
-T, --ctime |

Reading it¶
Each line is [seconds.microseconds] message, matching the usual dmesg format. The records are read from the ring buffer's descriptor array, so the order is the kernel's own, not a re-sort. The buffer starts with the version banner and the command line, which is a convenient cross-check against kl-kversion and kl-kcmdline.

Reading it¶
--ctime converts the monotonic timestamps to wall-clock form using the boot time the kernel recorded. It is useful for correlating with an exploit run that has its own timestamps.
Notes¶
printk_info.text_len is a u16 and the sequence number lives in printk_info, not in the text blob: reading either from the wrong place produces plausible but wrong lines. NUL bytes are stripped because GDB aborts the write on them.
