2016-05-20Make the fix for net/if.h fuckup even worse (#3287)Zbigniew Jędrzejewski-Szmek
The original conflict is fixed in the kernel in v4.6-rc7-40-g4a91cb61bb, but now our work-around causes a compilation failure. Keep the workaround to support 4.5 kernels for now, and layer more ugliness on top. Tested with: kernel-headers-4.6.0-1.fc25.x86_64 glibc-devel-2.23.90-18.fc25.x86_64 kernel-headers-4.5.4-300.fc24.x86_64 glibc-devel-2.23.1-7.fc24.x86_64 kernel-headers-4.4.9-300.fc23.x86_64 glibc-devel-2.22-16.fc23.x86_64 kernel-headers-4.1.13-100.fc21.x86_64 glibc-devel-2.20-8.fc21.x86_64

2016-05-19systemctl: reload configuration when enabling sysv units too (#3297)Franck Bui
After enabling/disabling a unit, the daemon configuration is expected to be unless '--no-reload' option is passed. However this is not done when enabling a sysv units. This can lead to the following scenario: $ cp /etc/init.d/named /etc/init.d/foo $ systemctl enable foo foo.service is not a native service, redirecting to systemd-sysv-install Executing /usr/lib/systemd/systemd-sysv-install enable foo $ systemctl start foo Failed to start foo.service: Unit foo.service failed to load: No such file or directory. This can also be seen after installing a package providing a sysv service: the service can't be started unless 'daemon-reload' is called manually. This shouldn't be needed and this patch will fix this case too since during package installation, the service is expected to be enabled/disabled.
2016-05-19systemctl: restore the no-sync option for legacy halt (#3249)tblume
The sync() call on shutdown had been removed with commit 57371e5829a61e5ee6c9f98404dfc729d6c62608 together with the no-sync option for the shutdown commands. The sync call was restored in commit 4a3ad39957399c4a30fc472a804e72907ecaa4f9 but the no-sync option wasn't re-added. I think we should restore this option at least for the legacy halt command.
2016-05-18core/dbus: further simplify branch code (#3283)Jonathan Boulle
free_and_strdup already handles the NULL case for us, so we can remove an extraneous conditional check. As noted in https://github.com/systemd/systemd/pull/3279/files#r63687717
2016-05-18core: translate between IO and BlockIO settings to ease transitionTejun Heo
Due to the substantial interface changes in cgroup unified hierarchy, new IO settings are introduced. Currently, IO settings apply only to unified hierarchy and BlockIO to legacy. While the transition is necessary, it's painful for users to have to provide configs for both. This patch implements translation from one config set to another for configs which make sense. * The translation takes place during application of the configs. Users won't see IO or BlockIO settings appearing without being explicitly created. * The translation takes place only if there is no config for the matching cgroup hierarchy type at all. While this doesn't provide comprehensive compatibility, it should considerably ease transition to the new IO settings which are a superset of BlockIO settings. v2: - Update test-cgroup-mask.c so that it accounts for the fact that CGROUP_MASK_IO and CGROUP_MASK_BLKIO move together. Also, test/parent.slice now sets IOWeight instead of BlockIOWeight.
2016-05-18core: factor out io and blkio helper functions from cgroup_context_apply()Tejun Heo
Factor out the following functions out of cgroup_context_apply() * cgroup_context_[blk]io_weight() * cgroup_apply_[blk]io_device_weight() * cgroup_apply_[blk]io_device_limit() This is pure refactoring and shouldn't cause any functional differences.
2016-05-18core: update CGroupBlockIODeviceBandwidth to record both rbps and wbpsTejun Heo
CGroupBlockIODeviceBandwith is used to keep track of IO bandwidth limits for legacy cgroup hierarchies. Unlike the unified hierarchy counterpart CGroupIODeviceLimit, a CGroupBlockIODeviceBandwiddth records either a read or write limit and has a couple issues. * There's no way to clear specific config entry. * When configs are cleared for an IO direction of a unit, the kernel settings aren't cleared accordingly creating discrepancies. This patch updates CGroupBlockIODeviceBandwidth so that it behaves similarly to CGroupIODeviceLimit - each entry records both rbps and wbps limits and is cleared if both are at default values after kernel settings are updated.
2016-05-18core: add support for IOReadIOPSMax and IOWriteIOPSMaxTejun Heo
cgroup IO controller supports maximum limits for both bandwidth and IOPS but systemd resource control currently only supports bandwidth limits. This patch adds support for IOReadIOPSMax and IOWriteIOPSMax when unified cgroup hierarchy is in use. It isn't difficult to also add BlockIOReadIOPS and BlockIOWriteIOPS for legacy hierarchies but IO control on legacy hierarchies is half-broken anyway, so let's leave it alone for now.
2016-05-18core: introduce CGroupIOLimitType enumsTejun Heo
Currently, there are two cgroup IO limits, bandwidth max for read and write, and they are hard-coded in various places. This is fine for two limits but IO is expected to grow more limits - low, high and max limits for bandwidth and IOPS - and hard-coding each limit won't make sense. This patch replaces hard-coded limits with an array indexed by CGroupIOLimitType and accompanying string and default value tables so that new limits can be added trivially.

2016-05-17networkd: Add EmitRouter= option for DHCP Server (#3251)Clemens Gruber
Add an option to disable appending DHCP option 3 (Router) to the DHCP OFFER and ACK packets. This commit adds the boolean option EmitRouter= for the [DHCPServer] section in .network files. Rationale: On embedded devices, it is very useful to have a DHCP server running on an USB OTG ethernet gadget interface to avoid manual setup on the client PCs, but it should only serve IP addresses, no route(r)s. Otherwise, Windows clients experience network connectivity issues, due to them using the address set in DHCP option 3 as default gateway. Signed-off-by: Clemens Gruber <clemens.gruber@pqgruber.com>

2016-05-17network: rely on ether_addr_from_string instead of sscanfDaniel Kahn Gillmor
2016-05-17util-lib: add ether_addr_from_string()Daniel Kahn Gillmor
This isn't quite symmetrical to in_addr_from_string() because it also returns an offset indicating how much of the string was consumed by the matched pattern. This offset reporting is needed for either of the following use cases: * verifying the lack of trailing garbage after such an address * parsing subsequent data from the same string
2016-05-17basic: define HEXDIGITSDaniel Kahn Gillmor
define HEXDIGITS alongside DIGITS, and use it where it's already useful. We'll use it again shortly when parsing MAC addresses.
2016-05-17network: test MAC address parsingDaniel Kahn Gillmor
networkd currently silently accepts some strings as MAC addresses that it probably shouldn't (like "ab:cd:ef:12:34:56:78" and "ab:cd:ef:12:3 4:56"). Add tests to MAC address parsing to ensure that we only accept valid MAC addresses, and that we accept the three most common forms of MAC address (colon-delimited hex, IEEE, and Cisco) Several of these tests currently fail, but another commit in this series will resolve them.

2016-05-16core: don't log job status message in case job was effectively NOP (#3199)Michal Sekletar
We currently generate log message about unit being started even when unit was started already and job didn't do anything. This is because job was requested explicitly and hence became anchor job of the transaction thus we could not eliminate it. That is fine but, let's not pollute journal with useless log messages. $ systemctl start systemd-resolved $ systemctl start systemd-resolved $ systemctl start systemd-resolved Current state: $ journalctl -u systemd-resolved | grep Started May 05 15:31:42 rawhide systemd[1]: Started Network Name Resolution. May 05 15:31:59 rawhide systemd[1]: Started Network Name Resolution. May 05 15:32:01 rawhide systemd[1]: Started Network Name Resolution.

2016-05-15networkd: do not generate a mac address for vlan interfaces (#3221)Susant Sahani

2016-05-09locale-util: mark special_glyph() as _const_Zbigniew Jędrzejewski-Szmek
_const_ means that the caller can assume that the function will return the same result every time (and will not modify global memory). special_glyph() meets this: even though it depends on global memory, that part of global memory is not expected to change. This allows the calls to special_glyph() to be optimized, even if -flto is not used.

Also remove "DRAW_" prefix from character names, TREE_* and ARROW and BLACK_CIRCLE are unambigous on their own, don't draw anything, and are always used as an argument to special_glyph(). Rename "DASH" to "MDASH", as there's more than one type of dash.
