2016-06-06time-util: add triple timestamp objectLennart Poettering
We already have a double timestamp object that we use whenever we need both a MONOTONIC and a REALTIME timestamp taken and stored. With this change we also add a triple timestamp object that in addition stores a BOOTTIME timestamp, which is useful for a few usecases. Note that we keep dual_timestamp around, as it is useful in many cases where triple_timestamp is not, in particular because retrieving the monotonic and realtime timestamps is much cheaper on Linux that getting the boottime timestamp.
2016-06-06resolved: support IPv6 DNS servers on the local linkLennart Poettering
Make sure we can parse DNS server addresses that use the "zone id" syntax for local link addresses, i.e. "fe80::c256:27ff:febb:12f%wlp3s0", when reading /etc/resolv.conf. Also make sure we spit this out correctly again when writing /etc/resolv.conf and via the bus. Fixes: #3359

2016-05-29util-lib: Add sparc64 support for process creation (#3348)Michael Karcher
The current raw_clone function takes two arguments, the cloning flags and a pointer to the stack for the cloned child. The raw cloning without passing a "thread main" function does not make sense if a new stack is specified, as it returns in both the parent and the child, which will fail in the child as the stack is virgin. All uses of raw_clone indeed pass NULL for the stack pointer which indicates that both processes should share the stack address (so you better don't pass CLONE_VM). This commit refactors the code to not require the caller to pass the stack address, as NULL is the only sensible option. It also adds the magic code needed to make raw_clone work on sparc64, which does not return 0 in %o0 for the child, but indicates the child process by setting %o1 to non-zero. This refactoring is not plain aesthetic, because non-NULL stack addresses need to get mangled before being passed to the clone syscall (you have to apply STACK_BIAS), whereas NULL must not be mangled. Implementing the conditional mangling of the stack address would needlessly complicate the code. raw_clone is moved to a separete header, because the burden of including the assert machinery and sched.h shouldn't be applied to every user of missing_syscalls.h

2016-05-25networkd: set IFLA_INET6_ADDR_GEN_MODE as per stable_secretTom Yan
Although networkd has option (LinkLocalAddressing=) to toggle IPv6LL autoconfiguration, when it is enabled, the address is autoconfigured by the kernel, but not networkd. Therefore, we do not statically set IFLA_INET6_ADDR_GEN_MODE to IN6_ADDR_GEN_MODE_EUI64, but dynamically depending on whether stable_secret is set, just as what the kernel does by default. Note that this does NOT affect the global addresses configured by networkd.

ask-password: ask for passphrases not only on the first console
2016-05-24ask-password: ask for passphrases not only on the first console of /dev/consoleWerner Fink
but also on all other consoles. This does help on e.g. mainframes where often a serial console together with other consoles are used. Even rack based servers attachted to both a serial console as well as having a virtual console do sometimes miss a connected monitor. To be able to ask on all terminal devices of /dev/console the devices are collected. If more than one device are found, then on each of the terminals a inquiring task for passphrase is forked and do not return to the caller. Every task has its own session and its own controlling terminal. If one of the tasks does handle a password, the remaining tasks will be terminated. Also let contradictory options on the command of systemd-tty-ask-password-agent fail. Spwan for each device of the system console /dev/console a own process. Replace the system call wait() with with system call waitid(). Use SIGTERM instead of SIGHUP to get unresponsive childs down. Port the collect_consoles() function forward to a pulbic and strv based function "get_kernel_consoles()" in terminal-util.c and use this in tty-ask-password-agent.c.

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.
2016-05-17util-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

This is useful for custom initramfs units that may modify the root disk partition table, where the root device is not known in advance (it's dynamically selected by the generators).

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.
2016-05-09tree-wide: rename draw_special_char to special_glyphZbigniew Jędrzejewski-Szmek
That function doesn't draw anything on it's own, just returns a string, which sometimes is more than one character. 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.

2016-05-06core: rework how we flush incoming traffic when a socket unit goes downLennart Poettering
Previously, we'd simply close and reopen the socket file descriptors. This is problematic however, as we won't transition through the SOCKET_CHOWN state then, and thus the file ownership won't be correct for the sockets. Rework the flushing logic, and actually read any queued data from the sockets for flushing, and accept any queued messages and disconnect them.
2016-05-05core: add io controller support on the unified hierarchyTejun Heo
On the unified hierarchy, blkio controller is renamed to io and the interface is changed significantly. * blkio.weight and blkio.weight_device are consolidated into io.weight which uses the standardized weight range [1, 10000] with 100 as the default value. * blkio.throttle.{read|write}_{bps|iops}_device are consolidated into io.max. Expansion of throttling features is being worked on to support work-conserving absolute limits (io.low and io.high). * All stats are consolidated into io.stats. This patchset adds support for the new interface. As the interface has been revamped and new features are expected to be added, it seems best to treat it as a separate controller rather than trying to expand the blkio settings although we might add automatic translation if only blkio settings are specified. * io.weight handling is mostly identical to blkio.weight[_device] handling except that the weight range is different. * Both read and write bandwidth settings are consolidated into CGroupIODeviceLimit which describes all limits applicable to the device. This makes it less painful to add new limits. * "max" can be used to specify the maximum limit which is equivalent to no config for max limits and treated as such. If a given CGroupIODeviceLimit doesn't contain any non-default configs, the config struct is discarded once the no limit config is applied to cgroup. * lookup_blkio_device() is renamed to lookup_block_device().

2016-05-05tree-wide: introduce new SOCKADDR_UN_LEN() macro, and use it everywhereLennart Poettering
The macro determines the right length of a AF_UNIX "struct sockaddr_un" to pass to connect() or bind(). It automatically figures out if the socket refers to an abstract namespace socket, or a socket in the file system, and properly handles the full length of the path field. This macro is not only safer, but also simpler to use, than the usual offsetof() + strlen() logic.

2016-05-03strbuf: set the proper character when creating new nodesLubomir Rintel
Commit 82501b3fc added an early break when a terminal node is found to incorrect place -- before setting c. This caused trie to be built that does not correspond to what it points to in buffer, causing incorrect deduplications: # cat /etc/udev/rules.d/99-bug.rules ENV{FOO}=="0" ENV{xx0}=="BAR" ENV{BAZ}=="00" # udevadm test * RULE /etc/udev/rules.d/99-bug.rules:1, token: 0, count: 2, label: '' M ENV match 'FOO' '0'(plain) * RULE /etc/udev/rules.d/99-bug.rules:2, token: 2, count: 2, label: '' M ENV match 'xx0' 'BAR'(plain) * RULE /etc/udev/rules.d/99-bug.rules:3, token: 4, count: 2, label: '' M ENV match 'BAZ' 'x0'(plain) * END The addition of "xx0" following "0" will cause a trie like this to be created: c=\0 c=0 "0" c=0 "xx0" <-- note the c is incorrect here, causing "00" to be c=O "FOO" deduplicated to it c=R "BAR" This in effect caused the usb_modeswitch rule for Huawei modems to never match and this never be switched to serial mode from mass storage.
