linux-toradex.git/include/linux/syslog.h, branch Colibri_T30_LinuxImageV2.1Beta2_20140206 Linux kernel for Apalis and Colibri modules syslog: use defined constants instead of raw numbers 2010-02-04T03:20:41+00:00 Kees Cook kees.cook@canonical.com 2010-02-03T23:37:13+00:00 d78ca3cd733d8a2c3dcd88471beb1a15d973eed8 Right now the syslog "type" action are just raw numbers which makes the source difficult to follow. This patch replaces the raw numbers with defined constants for some level of sanity.

syslog: distinguish between /proc/kmsg and syscalls 2010-02-04T03:20:12+00:00 Kees Cook kees.cook@canonical.com 2010-02-03T23:36:43+00:00 002345925e6c45861f60db6f4fc6236713fd8847 This allows the LSM to distinguish between syslog functions originating from /proc/kmsg access and direct syscalls. By default, the commoncaps will now no longer require CAP_SYS_ADMIN to read an opened /proc/kmsg file descriptor. For example the kernel syslog reader can now drop privileges after opening /proc/kmsg, instead of staying privileged with CAP_SYS_ADMIN. MAC systems that implement security_syslog have unchanged behavior.
