* Revert "dmesg: don't use brow/yellow in output"Karel Zak2014-04-231-1/+1
| | | | | | | | It will be better to support colors customization than use ugly blue color. BTW, for example git-log uses brow/yellow too by default. This reverts commit 0b6fbc25990d9498956e06bfcf699fca094e24a9.

| | | | | | | | | | | | | | | | | | | Earlier uptime determination, which was done with sysinfo(2), had one second resolution, which made time stamps to be rounded unstable way depending on when a dmesg command was executed. In practical terms; the command below was supposed not to differ but it did. $ diff -q <(dmesg --ctime) <(sleep 0.5 ; dmesg --ctime) [kzak@redhat.com: - add -lrt to Makemodule.am, - fallback to sysinfo() based boot time - use #ifdef] CC: Kay Sievers <kay@vrfy.org> References: https://lkml.org/lkml/2013/6/30/37 Buglink: https://github.com/karelzak/util-linux/issues/24 Signed-off-by: Sami Kerola <kerolasa@iki.fi> Signed-off-by: Karel Zak <kzak@redhat.com>

* dmesg: add iso-8601 time formatSami Kerola2013-07-011-3/+26
| | | | | | | | | | | The ISO-8601 should be welcomed by anyone who tries to parse dmesg time stamp, and compare them across servers. Time format tries to imitate coreutils 'date --iso-8601=ns' output, but instead of having nanoseconds the dmesg is using microseconds.

* dmesg: fix console-level off-by-oneBjørn Mork2012-10-021-5/+17
| | | | | | | | | | | | | | | | | | | | | | | | | | commit f06ec64f dmesg; support level names (e.g. --console-level=alert) introduced an off-by-one error. The kernel will print messages with a *higher* level than the console-level. The bug made it impossible to set the level for debugging, like it is documented in e.g Documentation/networking/netconsole.txt : nemi:/tmp# dmesg -n 8 dmesg: unknown level '8' And attempting to set the "emerg" level would result in an invalid 0 value: nemi:/tmp# dmesg -n emerg dmesg: klogctl failed: Invalid argument Restoring the old behaviour for numeric levels, and mapping the level names so that "dmesg -n debug" behaves as expected: logging everything at level "debug" and higher.

* dmesg: fix kmsg read if read returns EPIPEMilan Broz2012-08-131-3/+15
| | | | | | | | | | The /dev/kmsg can return EPIPE if current record has beed modified while reading. For init_kmsg, it cause switch to DMESG_METHOD_SYSLOG (which is not expected) and later it can truncate output. Signed-off-by: Milan Broz <mbroz@redhat.com>

| | | | | | | | | On old kernels (<3.5) kernel allows to open read-only /dev/kmsg for root, but read() returns -EINVAL. It means that open() is not enough to detect /dev/kmsg usability.
