2014-11-24smack: introduce new SmackProcessLabel optionWaLyong Cho
In service file, if the file has some of special SMACK label in ExecStart= and systemd has no permission for the special SMACK label then permission error will occurred. To resolve this, systemd should be able to set its SMACK label to something accessible of ExecStart=. So introduce new SmackProcessLabel. If label is specified with SmackProcessLabel= then the child systemd will set its label to that. To successfully execute the ExecStart=, accessible label should be specified with SmackProcessLabel=. Additionally, by SMACK policy, if the file in ExecStart= has no SMACK64EXEC then the executed process will have given label by SmackProcessLabel=. But if the file has SMACK64EXEC then the SMACK64EXEC label will be overridden. [zj: reword man page]

2014-07-07man: add a mapping for external manpagesZbigniew Jędrzejewski-Szmek
It is annoying when we have dead links on fd.o. Add project='man-pages|die-net|archlinux' to <citerefentry>-ies. In generated html, add external links to http://man7.org/linux/man-pages/man, http://linux.die.net/man/, https://www.archlinux.org/. By default, pages in sections 2 and 4 go to man7, since Michael Kerrisk is the autorative source on kernel related stuff. The rest of links goes to linux.die.net, because they have the manpages. Except for the pacman stuff, since it seems to be only available from archlinux.org. Poor gummiboot gets no link, because gummitboot(8) ain't to be found on the net. According to common wisdom, that would mean that it does not exist. But I have seen Kay using it, so I know it does, and deserves to be found. Can somebody be nice and put it up somewhere?

2014-06-06namespace: beef up read-only bind mount logicLennart Poettering
Instead of blindly creating another bind mount for read-only mounts, check if there's already one we can use, and if so, use it. Also, recursively mark all submounts read-only too. Also, ignore autofs mounts when remounting read-only unless they are already triggered.
2014-06-05core: don't include /boot in effect of ProtectSystem=Lennart Poettering
This would otherwise unconditionally trigger any /boot autofs mount, which we probably should avoid. ProtectSystem= will now only cover /usr and (optionally) /etc, both of which cannot be autofs anyway. ProtectHome will continue to cover /run/user and /home. The former cannot be autofs either. /home could be, however is frequently enough used (unlikey /boot) so that it isn't too problematic to simply trigger it unconditionally via ProtectHome=.
2014-06-04core: rename ReadOnlySystem= to ProtectSystem= and add a third value for ↵Lennart Poettering
also mounting /etc read-only Also, rename ProtectedHome= to ProtectHome=, to simplify things a bit. With this in place we now have two neat options ProtectSystem= and ProtectHome= for protecting the OS itself (and optionally its configuration), and for protecting the user's data.
2014-06-03core: add new ReadOnlySystem= and ProtectedHome= settings for service unitsLennart Poettering
ReadOnlySystem= uses fs namespaces to mount /usr and /boot read-only for a service. ProtectedHome= uses fs namespaces to mount /home and /run/user inaccessible or read-only for a service. This patch also enables these settings for all our long-running services. Together they should be good building block for a minimal service sandbox, removing the ability for services to modify the operating system or access the user's private data.

2014-03-25man: be more specific when EnvironmentFile= is readLennart Poettering

2014-03-24core: remove tcpwrap supportLennart Poettering
tcpwrap is legacy code, that is barely maintained upstream. It's APIs are awful, and the feature set it exposes (such as DNS and IDENT access control) questionnable. We should not support this natively in systemd. Hence, let's remove the code. If people want to continue making use of this, they can do so by plugging in "tcpd" for the processes they start. With that scheme things are as well or badly supported as they were from traditional inetd, hence no functionality is really lost.

As discussed on the ML these are useful to manage runtime directories below /run for services.
2014-02-26exec: imply NoNewPriviliges= only when seccomp filters are used in user modeLennart Poettering
2014-02-26core: add new RestrictAddressFamilies= switchLennart Poettering
This new unit settings allows restricting which address families are available to processes. This is an effective way to minimize the attack surface of services, by turning off entire network stacks for them. This is based on seccomp, and does not work on x86-32, since seccomp cannot filter socketcall() syscalls on that platform.
2014-02-21core: Add AppArmor profile switchingMichael Scherer
This permit to switch to a specific apparmor profile when starting a daemon. This will result in a non operation if apparmor is disabled. It also add a new build requirement on libapparmor for using this feature.

2014-02-14man: replace STDOUT with standard output, etc.Zbigniew Jędrzejewski-Szmek
Actually 'STDOUT' is something that doesn't appear anywhere: in the stdlib we have 'stdin', and there's only the constant STDOUT_FILENO, so there's no reason to use capitals. When refering to code, STDOUT/STDOUT/STDERR are replaced with stdin/stdout/stderr, and in other places they are replaced with normal phrases like standard output, etc.
2014-02-14man: fix grammatical errors and other formatting issuesJason St. John
* standardize capitalization of STDIN, STDOUT, and STDERR * reword some sentences for clarity * reflow some very long lines to be shorter than ~80 characters * add some missing <literal>, <constant>, <varname>, <option>, and <filename> tags
2014-02-13core: add SystemCallArchitectures= unit setting to allow disabling of non-nativeLennart Poettering
architecture support for system calls Also, turn system call filter bus properties into complex types instead of concatenated strings.
2014-02-12core: rework syscall filterLennart Poettering
- Allow configuration of an errno error to return from blacklisted syscalls, instead of immediately terminating a process. - Fix parsing logic when libseccomp support is turned off - Only keep the actual syscall set in the ExecContext, and generate the string version only on demand.

2014-02-10nspawn,man: use a common vocabulary when referring to selinux security contextsLennart Poettering
Let's always call the security labels the same way: SMACK: "Smack Label" SELINUX: "SELinux Security Context" And the low-level encapsulation is called "seclabel". Now let's hope we stick to this vocabulary in future, too, and don't mix "label"s and "security contexts" and so on wildly.
2014-02-10exec: Add support for ignoring errors on SELinuxContext by prefixing it with ↵Michael Scherer
-, like for others settings. Also remove call to security_check_context, as this doesn't serve anything, since setexeccon will fail anyway.
2014-02-10exec: Add SELinuxContext configuration itemMichael Scherer
This permit to let system administrators decide of the domain of a service. This can be used with templated units to have each service in a différent domain ( for example, a per customer database, using MLS or anything ), or can be used to force a non selinux enabled system (jvm, erlang, etc) to start in a different domain for each service.
2014-01-20exec: introduce PrivateDevices= switch to provide services with a private /devLennart Poettering
Similar to PrivateNetwork=, PrivateTmp= introduce PrivateDevices= that sets up a private /dev with only the API pseudo-devices like /dev/null, /dev/zero, /dev/random, but not any physical devices in them.

2013-10-02execute.c: always set $SHELLZbigniew Jędrzejewski-Szmek
In e6dca81 $SHELL was added to user@.service. Let's instead provide it to all units which have a user.
2013-09-27man: drop references to "cgroup" wher appropriateLennart Poettering
Since cgroups are mostly now an implementation detail of systemd lets deemphasize it a bit in the man pages. This renames systemd.cgroup(5) to systemd.resource-control(5) and uses the term "resource control" rather than "cgroup" where appropriate. This leaves the word "cgroup" in at a couple of places though, like for example systemd-cgtop and systemd-cgls where cgroup stuff is at the core of what is happening.
