2016-11-11basic/virt: fix userns check on CONFIG_USER_NS=n kernel (#4651)Zbigniew Jędrzejewski-Szmek
ENOENT should be treated as "false", but because of the broken errno check it was treated as an error. So ConditionVirtualization=user-namespaces probably returned the correct answer, but only by accident. Fixes #4608.
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.

2016-08-01virt: detect bhyve (FreeBSD hypervisor) (#3840)Leonardo Brondani Schenkel
The CPUID and DMI vendor strings do not seem to be documented. Values were found experimentally and by inspecting the source code.
2016-05-02util: don't dump /proc/cpuinfo contents in debug infoLennart Poettering
This is hardly useful, it's trivial for developers to get that info by running cat /proc/cpuinfo. Fixes #3155
2016-02-23basic: Bugfix Detect XEN Dom0 as no virtualizationStefan Schallenberg aka nafets227
When running in XEN Dom0 the virtualization check: 1) detect_xen returns HYPERVISOR_NONE so next checks are executed 2) /proc/sys/hypervisor detects a XEN hypervisor it is lacking the special Dom0 detection as in detect_xen With this patch, at the end of all virtualization checks we double-check if running in XEN Dom0 or DomU.

2016-02-10tree-wide: remove Emacs lines from all filesDaniel Mack
This should be handled fine now by .dir-locals.el, so need to carry that stuff in every file.

2015-12-01basic: re-sort includesThomas Hindoe Paaboel Andersen
My previous patch to only include what we use accidentially placed the added inlcudes in non-sorted order.
2015-11-30basic: include only what we useThomas Hindoe Paaboel Andersen
This is a cleaned up result of running iwyu but without forward declarations on src/basic.

2015-11-23virt: detect dmi before cpuidChristian Hesse
Virtualbox should be detected as 'oracle'. This used to work but broke with commit: commit 75f86906c52735c98dc0aa7e24b773edb42ee814 Author: Lennart Poettering <lennart@poettering.net> Date: Mon Sep 7 13:42:47 2015 +0200 basic: rework virtualization detection API We swap detection for dmi and cpuid, this fixes Virtualbox with KVM. Hopefully it does not break anything else.

2015-11-10virt: make sure that we detect unknown container managers as ↵Lennart Poettering
VIRTUALIZATION_CONTAINER_OTHER If we don't know a container manager, we should consider it as "other" rather than as no container manager at all, to provide a somwhat useful upgrade path.

2015-11-04detect-virt: dmi: look for KVMAndrew Jones
Some guests (ARM, AArch64, x86-RHEL) have 'KVM' in the product name. Look for that first in order to more precisely report "kvm" when detecting a QEMU/KVM guest. Without this patch we report "qemu", even if KVM acceleration is in use on ARM/AArch64 guests. I've only tested a backported version of this and the previous patch on an AArch64 guest (which worked). Of course it would be nice to get regression testing on all guest types that depend on dmi done.
2015-11-04arm/aarch64: detect-virt: check dmiAndrew Jones
ARM/AArch64 guests now have SMBIOS tables populated (when boot with a late enough QEMU and a late enough AAVMF is used as the bootloader). Furthermore, when booting ARM/AArch64 guests with ACPI, the DT detection obviously no longer works, so we need dmi detection.
2015-11-04detect-virt: detect in best-heuristic orderAndrew Jones
afaict, this will fix a regression caused by commit 75f86906c5. Where we used to report "kvm" before that patch, without this patch, we would only report "qemu". The reason is because cpuid detection must come before dmi detection. Also, both can safely come before other xen heuristics. Untested.

It's a very weak kind of virtualization, after all.

2015-10-24util-lib: split our string related calls from util.[ch] into its own file ↵Lennart Poettering
string-util.[ch] There are more than enough calls doing string manipulations to deserve its own files, hence do something about it. This patch also sorts the #include blocks of all files that needed to be updated, according to the sorting suggestions from CODING_STYLE. Since pretty much every file needs our string manipulation functions this effectively means that most files have sorted #include blocks now. Also touches a few unrelated include files.
2015-09-30fileio: make get_status_field() more genericAaro Koskinen
All users of get_status_field() expect the field pattern to occur in the beginning of a line, and the delimiter is ':'. Hardcode this into the function, and also skip any whitespace before ':' to support fields in files like /proc/cpuinfo. Add support for returning the full field value (currently stops on first whitespace). Rename the function so it's easier to ensure all callers switch to new semantics.
2015-09-07basic: rework virtualization detection APILennart Poettering
Introduce a proper enum, and don't pass around string ids anymore. This simplifies things quite a bit, and makes virtualization detection more similar to architecture detection.

2015-07-23virt: handle Virtualbox 5.0 with kvm hypervisorChristian Hesse
Virtualbox 5.0 now supports kvm hypervisor. In this case cpuid identidies as "kvm", which breaks units depending on ConditionVirtualization=oracle. So return "oracle" even with kvm hypervisor.
