2016-06-16resolved: when restarting a transaction make sure to not touch it anymore ↵Lennart Poettering
(#3553) dns_transaction_maybe_restart() is supposed to return 1 if the the transaction has been restarted and 0 otherwise. dns_transaction_process_dnssec() relies on this behaviour. Before this change in case of restart we'd call dns_transaction_go() when restarting the lookup, returning its return value unmodified. This is wrong however, as that function returns 1 if the transaction is pending, and 0 if it completed immediately, which is a very different set of return values. Fix this, by always returning 1 on redirection. The wrong return value resulted in all kinds of bad memory accesses as we might continue processing a transaction that was redirected and completed immediately (and thus freed). This patch also adds comments to the two functions to clarify the return values for the future. Most likely fixes: #2942 #3475 #3484

2016-06-16systemctl: delay pager/polkit agent opening as much as possibleZbigniew Jędrzejewski-Szmek
In https://github.com/systemd/systemd/issues/3543, we would open the pager before starting ssh, and the pipe fd was "leaked" into the ssh child as the stderr fd. Previous commit fixes bus-socket to nullify stderr before launching the child, but it seems reasonable to also delay starting the pager. If we are going to croak when trying to open the transport, it seems better to do this before starting the pager. This commit would also fix #3543 on its own.
2016-06-16systemctl: make sure we terminate the bus connection first, and then close ↵Lennart Poettering
the pager (#3550) If "systemctl -H" is used, let's make sure we first terminate the bus connection, and only then close the pager. If done in this order ssh will get an EOF on stdin (as we speak D-Bus through ssh's stdin/stdout), and then terminate. This makes sure the standard error we were invoked on is released by ssh, and only that makes sure we don't deadlock on the pager which waits for all clients closing its input pipe. (Similar fixes for the various other xyzctl tools that support both pagers and -H) Fixes: #3543

2016-06-15load-fragment: ignore ENOTDIR/EACCES errors (#3510)Zbigniew Jędrzejewski-Szmek
If for whatever reason the file system is "corrupted", we want to be resilient and ignore the error, as long as we can load the units from a different place. Arch bug https://bugs.archlinux.org/task/49547. A user had an ntfs symlink (essentially a file) instead of a directory after restoring from backup. We should just ignore that like we would treat a missing directory, for general resiliency. We should treat permission errors similarly. For example an unreadable /usr/local/lib directory would prevent (user) instances of systemd from loading any units. It seems better to continue.

2016-06-14util-lib: rework get_process_cmdline() (#3529)Lennart Poettering
This reworks get_process_cmdline() quite substantially, fixing the following: - Fixes: https://github.com/systemd/systemd/pull/3512/commits/a4e3bf4d7ac2de51191ce136ee9361ba319e106c#r66837630 - The passed max_length is also applied to the "comm" name, if comm_fallback is set. - The right thing happens if max_length == 1 is specified - when the cmdline "foobar" is abbreviated to 6 characters the result is not "foobar" instead of "foo...". - trailing whitespace are removed before the ... suffix is appended. The 7 character abbreviation of "foo barz" is hence "foo..." instead of "foo ...". - leading whitespace are suppressed from the cmdline - a comprehensive test case is added

2016-06-14resolved: in the ResolveHostname() bus call, accept IP addresses with scopeLennart Poettering
When we get a literal IP address as string that includes a zone suffix, process this properly and return the parsed ifindex back to the client, and include it in the canonical name in case of a link-local IP address.
2016-06-14resolved: make sure we initialize the ifindex of direct zone answers properlyLennart Poettering
Previously, after checking the local zone for a reply and finding one we'd not initialize the answer ifindex from that. Let's fix that.

Apparently newer gcc versions are a bit more forgiving when assigning an "unsigned char*" pointer to something of a different type. Let's add the missing cast so that old gcc versions are fine, too.
2016-06-14systemctl: allow percent-based MemoryLimit= settings via systemctl set-propertyLennart Poettering
The unit files already accept relative, percent-based memory limit specification, let's make sure "systemctl set-property" support this too. Since we want the physical memory size of the destination machine to apply we pass the percentage in a new set of properties that only exist for this purpose, and can only be set.
2016-06-14util: introduce physical_memory_scale() to unify how we scale by physical memoryLennart Poettering

2016-06-14core: when receiving a memory limit via the bus, refuse 0Lennart Poettering
When parsing unit files we already refuse unit memory limits of zero, let's also refuse it when the value is set via the bus.

2016-06-14util: when determining the amount of memory on this system, take cgroup ↵Lennart Poettering
limit into account When determining the amount of RAM in the system, let's make sure we also read the root-level cgroup memory limit into account. This isn't particularly useful on the host, but in containers it makes sure that whatever memory the container got assigned is actually used for RAM size calculations.

2016-06-14manager: reduce complexity of unit_gc_sweep (#3507)Lukáš Nykrýn
When unit is marked as UNSURE, we are trying to find if it state was changed over and over again. So lets not go through the UNSURE states again. Also when we find a GOOD unit lets propagate the GOOD state to all units that this unit reference. This is a problem on machines with a lot of initscripts with different starting priority, since those units will reference each other and the original algorithm might get to n! complexity. Thanks HATAYAMA Daisuke for the expand_good_state code.

2016-06-14build: fix missing symbol for old kernel headers (#3530)Andrew Jeddeloh
Fix issue where IN6_ADDR_GEN_MODE_STABLE_PRIVACY is undefined but IFLA_INET6_ADDR_GEN_MODE is defined and thus the former does not get fixed in missing.h. This occurs with kernel headers new enough to have the IFLA_INET6_ADDR_GEN_MODE but old enough to not yet have IN6_ADDR_GEN_MODE_STABLE_PRIVACY (e.g. 3.18).
2016-06-13systemctl: rework "systemctl status" a bitLennart Poettering
This reworks "systemctl status" and "systemctl show" a bit. It removes the definition of the `property_info` structure, because we can simply reuse the existing UnitStatusInfo type for that. The "could not be found" message is now printed by show_one() itself (and not its caller), so that it is shown regardless by who the function is called. (This makes it necessary to pass the unit name to the function.) This also adds all properties found to a set, and then checks if any of the properties passed via "--property=" is mising in it, if so, a proper error is generated. Support for checking the PID file of a unit is removed, as this cannot be done reasonably client side (since the systemd instance we are talking to might sit on another host) Replaces: #3411 Fixes: #3425 Also see: #3504

2016-06-13nspawn: lock down system call filter a bitLennart Poettering
Let's block access to the kernel keyring and a number of obsolete system calls. Also, update list of syscalls that may alter the system clock, and do raw IO access. Filter ptrace() if CAP_SYS_PTRACE is not passed to the container and acct() if CAP_SYS_PACCT is not passed. This also changes things so that kexec(), some profiling calls, the swap calls and quotactl() is never available to containers, not even if CAP_SYS_ADMIN is passed. After all we currently permit CAP_SYS_ADMIN to containers by default, but these calls should not be available, even then.
