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 commit38ef4c2e43("syslog: check cap_syslog when dmesg_restrict") (2010-12), CAP_SYS_ADMIN was no longer needed. And in commitee24aebffb("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.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
