History

Jingzi Meng 09ce61e27d cap_syslog: remove CAP_SYS_ADMIN when dmesg_restrict

CAP_SYSLOG was separated from CAP_SYS_ADMIN and introduced in Linux
2.6.37 (2010-11). For a long time, certain syslog actions required
CAP_SYS_ADMIN or CAP_SYSLOG. Maybe it’s time to officially remove
CAP_SYS_ADMIN for more fine-grained control.

CAP_SYS_ADMIN was once removed but added back for backwards
compatibility reasons. In commit 38ef4c2e437d ("syslog: check cap_syslog
when dmesg_restrict") (2010-12), CAP_SYS_ADMIN was no longer needed. And
in commit ee24aebffb75 ("cap_syslog: accept CAP_SYS_ADMIN for now")
(2011-02), it was accepted again. Since then, CAP_SYS_ADMIN has been
preserved.

Now that almost 13 years have passed, the legacy application may have
had enough time to be updated.
