2016-02-28core: set NoNewPrivileges for seccomp if we don't have CAP_SYS_ADMINRonny Chevalier
The manpage of seccomp specify that using seccomp with SECCOMP_SET_MODE_FILTER will return EACCES if the caller do not have CAP_SYS_ADMIN set, or if the no_new_privileges bit is not set. Hence, without NoNewPrivilege set, it is impossible to use a SystemCall* directive with a User directive set in system mode. Now, NoNewPrivileges is set if we are in user mode, or if we are in system mode and we don't have CAP_SYS_ADMIN, and SystemCall* directives are used.

Among other fixes, add information about more architectures that are supported these days.
2016-02-13core: drop Capabilities= settingLennart Poettering
The setting is hardly useful (since its effect is generally reduced to zero due to file system caps), and with the advent of ambient caps an actually useful replacement exists, hence let's get rid of this. I am pretty sure this was unused and our man page already recommended against its use, hence this should be a safe thing to remove.

2015-11-25core: support <soft:hard> ranges for RLIMIT optionsKarel Zak
The new parser supports: <value> - specify both limits to the same value <soft:hard> - specify both limits the size or time specific suffixes are supported, for example LimitRTTIME=1sec LimitAS=4G:16G The patch introduces parse_rlimit_range() and rlim type (size, sec, usec, etc.) specific parsers. No code is duplicated now. The patch also sync docs for DefaultLimitXXX= and LimitXXX=. References: https://github.com/systemd/systemd/issues/1769

2015-11-11man: document automatic dependenciesLennart Poettering
For all units ensure there's an "Automatic Dependencies" section in the man page, and explain which dependencies are automatically added in all cases, and which ones are added on top if DefaultDependencies=yes is set. This is also done for systemd.exec(5), systemd.resource-control(5) and systemd.unit(5) as these pages describe common behaviour of various unit types.
2015-11-11execute: Add new PassEnvironment= directiveFilipe Brandenburger
This directive allows passing environment variables from the system manager to spawned services. Variables in the system manager can be set inside a container by passing `--set-env=...` options to systemd-spawn. Tested with an on-disk test.service unit. Tested using multiple variable names on a single line, with an empty setting to clear the current list of variables, with non-existing variables. Tested using `systemd-run -p PassEnvironment=VARNAME` to confirm it works with transient units. Confirmed that `systemctl show` will display the PassEnvironment settings. Checked that man pages are generated correctly. No regressions in `make check`.
2015-11-10core: accept time units for time-based resource limitsLennart Poettering
Let's make sure "LimitCPU=30min" can be parsed properly, following the usual logic how we parse time values. Similar for LimitRTTIME=. While we are at it, extend a bit on the man page section about resource limits. Fixes: #1772

2015-11-06core: support IEC suffixes for RLIMIT stuffKarel Zak
Let's make things more user-friendly and support for example LimitAS=16G rather than force users to always use LimitAS=16106127360. The change is relevant for options: [Default]Limit{FSIZE,DATA,STACK,CORE,RSS,AS,MEMLOCK,MSGQUEUE} The patch introduces config_parse_bytes_limit(), it's the same as config_parse_limit() but uses parse_size() tu support the suffixes.

Document support for commas as a separator and possibility of specifying ranges of CPU indices. Tested by regenerating the manpages locally and reading them on man.
2015-09-29core: allow setting WorkingDirectory= to the special value ~Lennart Poettering
If set to ~ the working directory is set to the home directory of the user configured in User=. This change also exposes the existing switch for the working directory that allowed making missing working directories non-fatal. This also changes "machinectl shell" to make use of this to ensure that the invoked shell is by default in the user's home directory. Fixes #1268.
2015-08-25man: add hyphen to improve man textLennart Poettering
2015-08-24core: optionally create LOGIN_PROCESS or USER_PROCESS utmp entriesLennart Poettering
When generating utmp/wtmp entries, optionally add both LOGIN_PROCESS and INIT_PROCESS entries or even all three of LOGIN_PROCESS, INIT_PROCESS and USER_PROCESS entries, instead of just a single INIT_PROCESS entry. With this change systemd may be used to not only invoke a getty directly in a SysV-compliant way but alternatively also a login(1) implementation or even forego getty and login entirely, and invoke arbitrary shells in a way that they appear in who(1) or w(1). This is preparation for a later commit that adds a "machinectl shell" operation to invoke a shell in a container, in a way that is compatible with who(1) and w(1).
2015-08-04man: Document invalid lines in EnvironmentFileRichard Maw
If a line doesn't contain an = separator, it is skipped, rather than raising an error. This is potentially useful, so let's document this behaviour.

2015-06-18man: revert dynamic paths for split-usr setupsTom Gundersen
This did not really work out as we had hoped. Trying to do this upstream introduced several problems that probably makes it better suited as a downstream patch after all. At any rate, it is not releaseable in the current state, so we at least need to revert this before the release. * by adjusting the path to binaries, but not do the same thing to the search path we end up with inconsistent man-pages. Adjusting the search path too would be quite messy, and it is not at all obvious that this is worth the effort, but at any rate it would have to be done before we could ship this. * this means that distributed man-pages does not make sense as they depend on config options, and for better or worse we are still distributing man pages, so that is something that definitely needs sorting out before we could ship with this patch. * we have long held that split-usr is only minimally supported in order to boot, and something we hope will eventually go away. So before we start adding even more magic/effort in order to make this work nicely, we should probably question if it makes sense at all.
2015-05-28man: generate configured paths in manpagesFilipe Brandenburger
In particular, use /lib/systemd instead of /usr/lib/systemd in distributions like Debian which still have not adopted a /usr merge setup. Use XML entities from man/custom-entities.ent to replace configured paths while doing XSLT processing of the original XML files. There was precedent of some files (such as systemd.generator.xml) which were already using this approach. This addresses most of the (manual) fixes from this patch: http://anonscm.debian.org/cgit/pkg-systemd/systemd.git/tree/debian/patches/Fix-paths-in-man-pages.patch?h=experimental-220 The idea of using generic XML entities was presented here: http://lists.freedesktop.org/archives/systemd-devel/2015-May/032240.html This patch solves almost all the issues, with the exception of: - Path to /bin/mount and /bin/umount. - Generic statements about preference of /lib over /etc. These will be handled separately by follow up patches. Tested: - With default configure settings, ran "make install" to two separate directories and compared the output to confirm they matched exactly. - Used a set of configure flags including $CONFFLAGS from Debian: http://anonscm.debian.org/cgit/pkg-systemd/systemd.git/tree/debian/rules Installed the tree and confirmed the paths use /lib/systemd instead of /usr/lib/systemd and that no other unexpected differences exist. - Confirmed that `make distcheck` still passes.

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.
