Replaces strerror() usage with log_netdev_error_errno()
2015-06-15everywhere: port everything to sigprocmask_many() and friendsLennart Poettering
This ports a lot of manual code over to sigprocmask_many() and friends. Also, we now consistly check for sigprocmask() failures with assert_se(), since the call cannot realistically fail unless there's a programming error. Also encloses a few sd_event_add_signal() calls with (void) when we ignore the return values for it knowingly.
2015-06-15firewall: rename fw-util.[ch] → firewall-util.[ch]Daniel Mack
The names fw-util.[ch] are too ambiguous, better rename the files to firewall-util.[ch]. Also rename the test accordingly.

Improve tun/tap logging by using the new log_*errno*() functions that set 'errno' explicitly. Also fix a bunch of incorrect errno/r confusions.

2015-06-11networkd: create "kernel" setting for IPForwardingNick Owens
In 5a8bcb674f71a20e95df55319b34c556638378ce, IPForwarding was introduced to set forwarding flags on interfaces in .network files. networkd sets forwarding options regardless of the previous setting, even if it was set by e.g. sysctl. This commit creates a new option for IPForwarding, "kernel", that preserves the sysctl settings rather than always setting them. See https://bugs.freedesktop.org/show_bug.cgi?id=89509 for the initial bug report.

2015-06-10libsystemd-network: use domain validation instead of hostname validation for ↵Nick Owens
dhcp domain option previously hostname_is_valid was used to validate domain names, which would silently drop perfectly valid dns names that were longer than a single dns label.

We ignore the return value of sd_device_get_devtype, then devtype could be uninitialized when used with streq_ptr. So we need to initialize it first.

2015-05-15networkd: don't touch global forwarding settingBenedikt Morbach
This reverts commit 43c6d5abacaebf813845934ec8d5e5ee3c431854 (and a small part of 4046d8361c55c80ab8577aea52523b9e6eab0d0c) It turns out we don't actually need to set the global ip_forward setting. The only relevant setting is the one on each interface. What the global toggle actually does is switch forwarding on/off for all currently present interfaces and change the default for new ones. That means that by setting the global ip_forward we - Introduce a race condition, because if the interface with IPForward=yes is brought up after one with IPForward=no, both will have forwarding enabled, because the global switch turns it on for all interfaces. If the other interface comes up first networkd correctly sets forward=0 and it doesn't get overridden. - Change the forwarding setting for interfaces that networkd is not configured to touch, even if the user disabled forwarding via sysctl, either globally or per-interface As forwarding works fine without this, as long as all relevant interfacest individually set IPForward=yes: just drop it This means that non-networkd interfaces use the global default while networkd interfaces default to off if IPForward isn't given.

2015-05-11core,network: major per-object logging reworkLennart Poettering
This changes log_unit_info() (and friends) to take a real Unit* object insted of just a unit name as parameter. The call will now prefix all logged messages with the unit name, thus allowing the unit name to be dropped from the various passed romat strings, simplifying invocations drastically, and unifying log output across messages. Also, UNIT= vs. USER_UNIT= is now derived from the Manager object attached to the Unit object, instead of getpid(). This has the benefit of correcting the field for --test runs. Also contains a couple of other logging improvements: - Drops a couple of strerror() invocations in favour of using %m. - Not only .mount units now warn if a symlinks exist for the mount point already, .automount units do that too, now. - A few invocations of log_struct() that didn't actually pass any additional structured data have been replaced by simpler invocations of log_unit_info() and friends. - For structured data a new LOG_UNIT_MESSAGE() macro has been added, that works like LOG_MESSAGE() but prefixes the message with the unit name. Similar, there's now LOG_LINK_MESSAGE() and LOG_NETDEV_MESSAGE(). - For structured data new LOG_UNIT_ID(), LOG_LINK_INTERFACE(), LOG_NETDEV_INTERFACE() macros have been added that generate the necessary per object fields. The old log_unit_struct() call has been removed in favour of these new macros used in raw log_struct() invocations. In addition to removing one more function call this allows generated structured log messages that contain two object fields, as necessary for example for network interfaces that are joined into another network interface, and whose messages shall be indexed by both. - The LOG_ERRNO() macro has been removed, in favour of log_struct_errno(). The latter has the benefit of ensuring that %m in format strings is properly resolved to the specified error number. - A number of logging messages have been converted to use log_unit_info() instead of log_info() - The client code in sysv-generator no longer #includes core code from src/core/. - log_unit_full_errno() has been removed, log_unit_full() instead takes an errno now, too. - log_unit_info(), log_link_info(), log_netdev_info() and friends, now avoid double evaluation of their parameters
2015-05-04network: Implement fallback DHCPv6 prefix handling for older kernelsPatrik Flykt
When setting IPv6 addresses acquired by DHCPv6, systemd-networkd sets the IFA_F_NOPREFIXROUTE flag in the IFA_FLAGS netlink attribute. As the flag and the attribute are present starting with Linux 3.14, older kernels will need systemd-network to manage prefix route expiry. By default, DHCPv6 addresses are first assigned setting the IFA_F_NOPREFIXROUTE flag in the IFA_FLAGS netlink attribute. Should the address assignment fail, the same assignment is tried without the IFA_FLAGS attribute. Should also the second attempt fail, an error is printed and address assignment ends with failure. As successful use of the IFA_FLAGS netlink attribute is recorded in the Link structure, the DHCPv6 code will know if the kernel or systemd-network fallback code handles expiring prefixes. The prefix expiration and IPv6 address updating fallback code is resurrected from the parts deleted with commit 47d45d3cde45d6545367570264e4e3636bc9e345. This patch can be removed once the minimum kernel requirements are greater than or equal to 3.14.

2015-04-21networkd: improve how networkd logs thingsLennart Poettering
This makes adds a couple of fixes: - Introduces log_netdev_error_errno() and friends, which takes an error number, and matches what log_link_error_errno() and friends do. - Replaces a lof ot strerror() usage with log_netdev_error_errno(), log_link_error_errno() and log_erro_errno() - Uppercases the first character of many log messages, after all this is supposed to be english language - Drops manual negating of error codes before passing them to log functions, the log functions all do that internally anyway. Some other minor fixes. Behaviour should not change really.
