tree-wide: remove Emacs lines from all files This should be handled fine now by .dir-locals.el, so need to carry that stuff in every file.

capabilities: added support for ambient capabilities. This patch adds support for ambient capabilities in service files. The idea with ambient capabilities is that the execed processes can run with non-root user and get some inherited capabilities, without having any need to add the capabilities to the executable file. You need at least Linux 4.3 to use ambient capabilities. SecureBit keep-caps is automatically added when you use ambient capabilities and wish to change the user. An example system service file might look like this: [Unit] Description=Service for testing caps [Service] ExecStart=/usr/bin/sleep 10000 User=nobody AmbientCapabilities=CAP_NET_ADMIN CAP_NET_RAW After starting the service it has these capabilities: CapInh: 0000000000003000 CapPrm: 0000000000003000 CapEff: 0000000000003000 CapBnd: 0000003fffffffff CapAmb: 0000000000003000

capabilities: keep bounding set in non-inverted format. Change the capability bounding set parser and logic so that the bounding set is kept as a positive set internally. This means that the set reflects those capabilities that we want to keep instead of drop.

basic: include only what we use This is a cleaned up result of running iwyu but without forward declarations on src/basic.

src/basic: rename audit.[ch] → audit-util.[ch] and capability.[ch] → capability-util.[ch] The files are named too generically, so that they might conflict with the upstream project headers. Hence, let's add a "-util" suffix, to clarify that this are just our utility headers and not any official upstream headers.
