2015-04-03bootchart: clean up sysfd and proc handlingDaniel Mack
Retrieve the handle to procfs in main(), and pass it functions that need it. Kill the global variables. Also, refactor lots of code in svg_title(). There's no need to access any global variables from there either, and we really should return proper errors from there as well.
2015-04-03bootchart: clean up control flow logicDaniel Mack
Don't blindly exit() from random functions, but return a proper error and upchain error conditions. squash! bootchart: clean up control flow logic When pread() returns "0", it's a read failure, so don't make the caller think log_sample() was successful, return meaningful error code instead of 0.
2015-04-03bootchart: switch to log_* helpersDaniel Mack
Let the helper functions take care of the string message output.

2015-04-03units: explicitly require /var, /tmp and /var/tmp to be mounted before ↵Lennart Poettering
basic.target We support /var, /tmp and /var/tmp on NFS. NFS shares however are by default ordered only before remote-fs.target which is a late-boot service. /var, /tmp, /var/tmp need to be around earlier though, hence explicitly order them before basic.target. Note that this change simply makes explicit what was implicit before, since many early-boot services pulled in parts of /var anyway early.

nss-user-lookup.target We should not allow logins before NIS/LDAP users are available.
2015-04-03units: move After=systemd-hwdb-update.service dependency from udev to ↵Lennart Poettering
udev-trigger Let's move the hwdb regeneration a bit later. Given that hwdb is non-essential it should be OK to allow udev to run without it until we do the full trigger. http://lists.freedesktop.org/archives/systemd-devel/2015-April/030074.html
2015-04-03CODING_STYLE: mention that dup() should not be usedLennart Poettering
2015-04-02timedatectl: many fixesLennart Poettering
- print runtime warnings with log_warning() - save and restore $TZ properly - Get rid of exit() pseudo error handling - Using time() is OK when connecting to a local container or when showing data about local host, but certainly not for remote hosts.
2015-04-02man: don't mention "journalctl /dev/sda"Lennart Poettering
It never worked, and nobody ever worked on it, hence don't mention it.

2015-04-02libsystemd: add sd-device libraryTom Gundersen
This provides equivalent functionality to libudev-device, but in the systemd style. The public API only caters to creating sd_device objects from for devices that already exist in /sys, there is no support for listening for monitoring events or creating devices received over the udev netlink protocol. The private API contains the necessary functionality to make sd-device a drop-in replacement for libudev-device, but which we would not otherwise want to export.

The dev_port concept is a bit confusing, expand on the comment a bit.

I'd argue that having firmware labels for such devices makes no sense, but they exist, so make sure we handle them as best as we can.

2015-04-01mount: don't run quotaon only for network filesystemsLukas Nykryn
If you have for example ext4 on iscsi devices it is possible to setup qoutas there. Unfortunately, because such fstab entry contains _netdev, systemd will not add dependency to quotaon.service.

2015-03-31nspawn: fallback on bind mount when mknod failsAlban Crequy
Some systems abusively restrict mknod, even when the device node already exists in /dev. This is unfortunate because it prevents systemd-nspawn from creating the basic devices in /dev in the container. This patch implements a workaround: when mknod fails, fallback on bind mounts. Additionally, /dev/console was created with a mknod with the same major/minor as /dev/null before bind mounting a pts on it. This patch removes the mknod and creates an empty regular file instead. In order to test this patch, I used the following configuration, which I think should replicate the system with the abusive restriction on mknod: # grep devices /proc/self/cgroup 4:devices:/user.slice/restrict # cat /sys/fs/cgroup/devices/user.slice/restrict/devices.list c 1:9 r c 5:2 rw c 136:* rw # systemd-nspawn --register=false -D . v2: - remove "bind", it is not needed since there is already MS_BIND v3: - fix error management when calling touch() - fix lowercase in error message
2015-03-31nspawn: drop sd_booted() checkLennart Poettering
We have no such check in any of the other tools, hence don't have one in nspawn either. (This should make things nicer for Rocket, among other things) Note: removing this check does not mean that we support running nspawn on non-systemd. We explicitly don't. It just means that we remove the check for running it like that. You are still on your own if you do...

2015-03-31ARM: detect-virt: detect QEMU/KVMAndrew Jones
QEMU/KVM guests do not have hypervisor nodes, but they do have fw-cfg nodes (since qemu v2.3.0-rc0). fw-cfg nodes are documented, see kernel doc Documentation/devicetree/bindings/arm/fw-cfg.txt, and therefore we should be able to rely on it in this detection. Unfortunately, we currently don't have enough information in the DT, or elsewhere, to determine if we're using KVM acceleration with QEMU or not, so we can only report 'qemu' at this time, even if KVM is in use. This shouldn't really matter in practice though, because if detect-virt is used interactively it will be clear to the user whether or not KVM acceleration is present by the overall speed of the guest. If used by a script, then the script's behavior should not change whether it's 'qemu' or 'kvm'. QEMU emulated guests and QEMU/KVM guests of the same type should behave identically, only the speed at which they run should differ.

2015-03-31detect-virt: use /proc/device-treeAndrew Jones
Kernel doc Documentation/ABI/testing/sysfs-firmware-ofw says that the /proc/device-tree symlink should be used, as opposed to directly accessing /sys/firmware/devicetree/base. The former is ABI, but not the later.
2015-03-30systemd-bootchart: Repair Entropy GraphAlexander Sverdlin
Entropy Graph code doesn't handle the error condition if open() of /proc entry fails. Moreover, the file is only opened once and only first sample will contain the correct value because the return value of pread() is also not handled properly and file is not re-opened. Fix both problems.
2015-03-30systemd-bootchart: Prevent leaking file descriptors in open-fdopen combinationAlexander Sverdlin
Correctly handle the potential failure of fdopen() (because of OOM, for instance) after potentially successful open(). Prevent leaking open fd in such case.
2015-03-30systemd-bootchart: Prevent closing random file descriptorsAlexander Sverdlin
If the kernel has no CONFIG_SCHED_DEBUG option set, systemd-bootchart produces empty .svg file. The reason for this is very fragile file descriptor logic in log_sample() and main() (/* do some cleanup, close fd's */ block). There are many places where file descriptors are closed on failure (missing SCHED_DEBUG provokes it), but there are several problems with it: - following iterations in the loop see that the descriptor is non zero and do not open the corresponding file again; - "some cleanup" code closes already closed files and the descriptors are reused already, in particular for resulting .svg file; - static "vmstat" and "schedstat" variables in log_sample() made the situation even worse. These are the strace fragments: [...] close(7) = -1 EBADF (Bad file descriptor) close(-1) = -1 EBADF (Bad file descriptor) pread(7, 0xbea60a2c, 4095, 0) = -1 EBADF (Bad file descriptor) close(7) = -1 EBADF (Bad file descriptor) close(-1) = -1 EBADF (Bad file descriptor) pread(7, 0xbea60a2c, 4095, 0) = -1 EBADF (Bad file descriptor) close(7) = -1 EBADF (Bad file descriptor) close(-1) = -1 EBADF (Bad file descriptor) getdents64(4, /* 0 entries */, 32768) = 0 clock_gettime(CLOCK_MONOTONIC, {24, 783843501}) = 0 nanosleep({0, 5221792}, NULL) = 0 clock_gettime(CLOCK_MONOTONIC, {24, 789726835}) = 0 lseek(4, 0, SEEK_SET) = 0 pread(5, "nr_free_pages 52309\nnr_alloc_bat"..., 4095, 0) = 685 pread(6, "version 15\ntimestamp 4294939775\n"..., 4095, 0) = 86 getdents64(4, /* 99 entries */, 32768) = 2680 pread(7, 0xbea60a2c, 4095, 0) = -1 EBADF (Bad file descriptor) close(7) = -1 EBADF (Bad file descriptor) close(-1) = -1 EBADF (Bad file descriptor) pread(8, 0xbea60a2c, 4095, 0) = -1 EBADF (Bad file descriptor) close(8) = -1 EBADF (Bad file descriptor) close(-1) = -1 EBADF (Bad file descriptor) pread(9, 0xbea60a2c, 4095, 0) = -1 EBADF (Bad file descriptor) close(9) = -1 EBADF (Bad file descriptor) [...] where it obviously tries to close same and reused decriptors many times, also passing return code "-1" instead of descriptor...

2015-03-27networkd-dhcp6: Do not handle prefix expiryPatrik Flykt
Expiring prefixes need not be handled anymore as the kernel has been instructed not to create routes for DHCPv6 assigned addresses via the IFA_F_NOPREFIXROUTE flag.
2015-03-27systemd-networkd: Use IFA_F_NOPREFIXROUTE with IPv6 addressesPatrik Flykt
The IFA_F_NOPREFIXROUTE flag prevents the kernel from creating new onlink prefixes when a DHCPv6 IPv6 address with a prefix length is set from user space. IPv6 routing will follow the onlink status from Router Advertisment Prefix Information options or any manually set route, which is the correct thing to do. As this flag has a larger value than what fits into an unsigned char, update the flag attribute to an uint32_t and set it with an IFA_FLAGS attribute when writing netlink messages to the kernel.
2015-03-27sd-rtnl: Always enable IFA_FLAGSPatrik Flykt
IFA_FLAGS is a discrete value and has no preprocessor #define defined for it. Fix this by always using the value.
2015-03-26util: rework word parsing and c unescaping codeLennart Poettering
When parsing words from input files, optionally automatically unescape the passed strings, controllable via a new flags parameter. Make use of this in tmpfiles, and port everything else over, too. This improves parsing quite a bit, since we no longer have to process the same string multiple times with different calls, where an earlier call might corrupt the input for a later call.

2015-03-25fstab-generator: don't accept missing root=, but accept root=noneTobias Hunger
And other non-device entries (like fstab does). Mount whatever the user asked to be mounted on / on the kernel command line. Do less sanity check and do *not* bail out when the mount device looks strange or does not exist. This basically makes the changes for deviceless filesystems from yesterday unnecessary and is in line with what we do for filesystems set up in fstab. Remove some code that is now dead (reverting fb02a2775a65 and b0438462). [tomegun: - change patch title/description a bit. - don't touch the /usr logic, that would be a separate change and we don't currently have a convincing use-case for that. - don't bail out on /sys ro. This only makes sense in containers, where we would not be doing this anyway. If there is a use-case we could consider that as a separate patch.]
