2016-10-30man: make systemd-escape examples more consistentLucas Werkmeister
The first example wasn't phrased with "To ..." as the other three are, and the last example was lacking the colon.

The option does more than the documentation gave it credit for.

2016-10-27core: lets apply working directory just after mount namespacesDjalal Harouni
This makes applying groups after applying the working directory, this may allow some flexibility but at same it is not a big deal since we don't execute or do anything between applying working directory and droping groups.

2016-10-26units: disable /dev/hugepages in private user namespacesZbigniew Jędrzejewski-Szmek
The mount fails, even though CAP_SYS_ADMIN is granted.
2016-10-26condition: simplify condition_test_virtualizationZbigniew Jędrzejewski-Szmek
Rewrite the function to be slightly simpler. In particular, if a specific match is found (like ConditionVirtualization=yes), simply return an answer immediately, instead of relying that "yes" will not be matched by any of the virtualization names below. No functional change.

2016-10-26shared/condition: add ConditionVirtualization=[!]private-usersZbigniew Jędrzejewski-Szmek
This can be useful to silence warnings about units which fail in userns container.
2016-10-26detect-virt: add --private-users switch to check if a userns is activeZbigniew Jędrzejewski-Szmek
Various things don't work when we're running in a user namespace, but it's pretty hard to reliably detect if that is true. A function is added which looks at /proc/self/uid_map and returns false if the default "0 0 UINT32_MAX" is found, and true if it finds anything else. This misses the case where an 1:1 mapping with the full range was used, but I don't know how to distinguish this case. 'systemd-detect-virt --private-users' is very similar to 'systemd-detect-virt --chroot', but we check for a user namespace instead.

2016-10-26seccomp: also block shmat(..., SHM_EXEC) for MemoryDenyWriteExecuteTopi Miettinen
shmat(..., SHM_EXEC) can be used to create writable and executable memory, so let's block it when MemoryDenyWriteExecute is set.

2016-10-25test: skip exec tests when inaccessible dir is unavailableDongsu Park
In case of running test-execute on systems with systemd < v232, several tests like privatedevices or protectkernelmodules fail because /run/systemd/inaccessible/ doesn't exist. In these cases, we should skip tests to avoid unnecessary errors. See also https://github.com/systemd/systemd/pull/4243#issuecomment-253665566

Properly synthesize -.slice and init.scope
2016-10-24networkd: fix mixup of bond options (#4470)Benjamin Richter
2016-10-24core: drop -.slice from shipped unitsLennart Poettering
Since this unit is synthesized anyway there's no point in actually shipping it on disk. This also has the benefit that "cd /usr/lib/systemd/system ; ls *" won't be confused by the leading dash of the file name anymore.
2016-10-24core: move initialization of -.slice and init.scope into the unit_load() ↵Lennart Poettering
callbacks Previously, we'd synthesize the root slice unit and the init scope unit in the enumerator callbacks for the unit type. This is problematic if either of them is already referenced from a unit that is loaded as result of another unit type's enumerator logic. Let's clean this up and simply create the two objects from the enumerator callbacks, if they are not around yet. Do the actual filling in of the settings from the unit_load() callbacks, to match how other units are loaded. Fixes: #4322
2016-10-24man: sync up the suggested nsswitch.conf configuration for our four NSS modulesLennart Poettering
This unifies the suggested nsswitch.conf configuration for our four NSS modules to this: hosts: files mymachines resolve [!UNAVAIL=return] dns myhostname Note that this restores "myhostname" to the suggested configuration of nss-resolve for the time being, undoing 4484e1792b64b01614f04b7bde97bf019f601bf9. "myhostname" should probably be dropped eventually, but when we do this we should do it in full, and not only drop it from the suggested nsswitch.conf for one of the modules, but also drop it in source and stop referring to it altogether. Note that nss-resolve doesn't replace nss-myhostname in full: the former only works if D-Bus/resolved is available for resolving the local hostname, the latter works in all cases even if D-Bus or resolved are not in operation, hence there's some value in keeping the line as it is right now. Note that neither dns nor myhostname are considered at all with the above configuration unless the resolve module actually returns UNAVAIL. Thus, even though handling of local hostname resolving is implemented twice this way it is only executed once for each lookup.
2016-10-24nss-resolve: be a bit more careful with returning NSS_STATUS_NOTFOUNDLennart Poettering
Let's tighten the cases when our module returns NSS_STATUS_NOTFOUND. Let's do so only if we actually managed to talk to resolved. In all other cases stick to NSS_STATUS_UNAVAIL as before, as it clearly indicates that our module or the system is borked, and the "dns" fallback should really take place. In particular this fixes the 2nd-level fallback from our own dlopen() based fallback handling. In this case we really should return UNAVAIL so that the caller can apply its own fallback still. Fix-up for d7247512a904f1dd74125859d8da66166c2a6933. Note that our own dlopen() based fallback is pretty much redundant now if nsswitch.conf is configured like this: hosts: files mymachines resolve [!UNAVAIL=return] dns myhostname In a future release we should probably drop our internal fallback then, in favour of this nsswitch.conf-based one.

2016-10-24Various additions to NEWSLennart Poettering
2016-10-24seccomp: add test-seccomp test toolLennart Poettering
This validates the system call set table and many of our seccomp-util.c APIs.
2016-10-24seccomp: add new helper call seccomp_load_filter_set()Lennart Poettering
This allows us to unify most of the code in apply_protect_kernel_modules() and apply_private_devices().
2016-10-24seccomp: two fixes for the syscall set tablesLennart Poettering
"oldumount()" is not a syscall, but simply a wrapper for it, the actual syscall nr is called "umount" (and the nr of umount() is called umount2 internally). "sysctl()" is not a syscall, but "_syscall()" is. Fix this in the table. Without these changes libseccomp cannot actually translate the tables in full. This wasn't noticed before as the code was written defensively for this case.
2016-10-24seccomp: add new seccomp_init_conservative() helperLennart Poettering
This adds a new seccomp_init_conservative() helper call that is mostly just a wrapper around seccomp_init(), but turns off NNP and adds in all secondary archs, for best compatibility with everything else. Pretty much all of our code used the very same constructs for these three steps, hence unifying this in one small function makes things a lot shorter. This also changes incorrect usage of the "scmp_filter_ctx" type at various places. libseccomp defines it as typedef to "void*", i.e. it is a pointer type (pretty poor choice already!) that casts implicitly to and from all other pointer types (even poorer choice: you defined a confusing type now, and don't even gain any bit of type safety through it...). A lot of the code assumed the type would refer to a structure, and hence aded additional "*" here and there. Remove that.
2016-10-24core: rework apply_protect_kernel_modules() to use ↵Lennart Poettering
seccomp_add_syscall_filter_set() Let's simplify this call, by making use of the new infrastructure. This is actually more in line with Djalal's original patch but instead of search the filter set in the array by its name we can now use the set index and jump directly to it.
