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.]
2015-03-24tmpfiles: avoid out of bounds readThomas Hindoe Paaboel Andersen
Otherwise this will go wrong for 'v'.
2015-03-24timedatectl: remove unused variablesThomas Hindoe Paaboel Andersen
2015-03-24timedate: remove daylight saving time handling and tzfile parserKay Sievers
We planned to support (the conceptually broken) daylight saving time/local time features in the kernel, SCSI, networking, FAT filesystem, but it turned out to be a race we cannot win and do not want to get involved. Systemd should not fiddle with daylight saving time or parse timezone information itself. Leave everything to glibc or tools like date(1) and do not make any promises or raise expectations that systemd should handle anything like this.
2015-03-24timedatectl: fix when queried system has differn't timezoneShawn Landden
Also allow getting time from time(2) when BUS_TRANSPORT_MACHINE. v2: check for error
2015-03-24bootchart: more useful error message for common errorShawn Landden

2015-03-24bootchart: remove duplicated code, prevent creating empty filesShawn Landden
In Debian and rawhide Fedora, which have CONFIG_SCHEDSTATS=n, bootchart creates empty files in /run/log before printing an error. Stop doing that. Moreover this duplicated part of the code doesn't even have error checking so there is no error avoided by doing this early. Reported-by: tfirg_ on IRC
2015-03-24fstab-generator: Do not check deviceless filesystemsTobias Hunger
There is no need to check those.
2015-03-24fstab-generator: Support root on tmpfs (or other deviceless FS)Tobias Hunger
This allows for stateless systems.
2015-03-23sd-rtnl: handle empty multi-part message from the kernelAlin Rauta
We strips out NLMSG_DONE piece from a multi-part message adding into the receive queue only the messages containing actual data. If we send a request to the kernel for getting the forwarding database table (just an example), the response will be a multi-part message like below: 1. FDB entry 1; 2. FDB entry 2; 3. NLMSG_DONE; We strip out "3. NLMSG_DONE;" part and places into the receive queue a pointer to "1. FDB entry 1; 2. FDB entry 2". But if the FDB table is empty, the respose from the kernel will look like below: 1. NLMSG_DONE; We strip out "1. NLMSG_DONE;" part and since there is no actual data got, it continues waiting until reaching timeout. Therefore, a call to "sd_rtnl_call" to send and wait for a response from kernel will exit with timeout which is interpreted as error in communication. This patch puts the NLMSG_DONE message on the receive queue if it ends an empty multi-part message. This situation is detected in sd_rtnl_call() and in the callback code and NULL is returned to the caller instead. [tomegun: - added/reworded commit message - extend the same support to sd_rtnl_call_async() - drop debug logging from library, we only do this if something is really wrong, but an empty multi-part message is perfectly normal - modernize the code we touch whilst we are at it]
2015-03-21timedated: fix enable/disable reversalZbigniew Jędrzejewski-Szmek
Bug introduced in 984f1b1d1b. The state was flipped later, but the enable/disable routine made use of the state to decide what to do. context_enable_ntp() and context_start_ntp() now get the desired state directly, so the Context parameter can be removed.
2015-03-21core: make SELinux enable/disable check symmetricZbigniew Jędrzejewski-Szmek
We'd use the generic check for disable, and a unit-file-specific one for enable. Use the more specific one both ways. systemd[1]: SELinux access check scon=system_u:system_r:systemd_timedated_t:s0 tcon=system_u:system_r:init_t:s0 tclass=system perm=disable path=(null) cmdline=/usr/lib/systemd/systemd-timedated: -13 systemd[1]: SELinux access check scon=system_u:system_r:systemd_timedated_t:s0 tcon=system_u:object_r:systemd_unit_file_t:s0 tclass=service perm=enable path=/usr/lib/systemd/system/systemd-timesyncd.service cmdline=/usr/lib/systemd/systemd-timedated: -13 https://bugzilla.redhat.com/show_bug.cgi?id=1014315
2015-03-21timedated: flip internal status after executing operationZbigniew Jędrzejewski-Szmek
timedated would set the internal status before calling out to systemd to do the actual change. When the operation was refused because of a SELinux denial, the state kept in timedated would get out of sync, and the second call from timedatectl would appear to succeed. https://bugzilla.redhat.com/show_bug.cgi?id=1014315
2015-03-21missing.h: add more btrfs types and definesMichael Olbrich
2015-03-21fstab-generator: ignore invalid swap priorityZbigniew Jędrzejewski-Szmek
A failed priority is not something worth stopping boot over. Most people have only one swap device, in which case priority is irrelevant, and even if there is more than one swap device, they are all usable, and ignoring the priority field should only result in some loss of performance. The kernel will report the priority as -1 if not set, so it's easy for people to make this mistake. https://bugzilla.redhat.com/show_bug.cgi?id=1204336
2015-03-21networkd: use LOG_WARN not LOG_ERR for non-fatal errorsZbigniew Jędrzejewski-Szmek
2015-03-21shared/mkdir: do not set errno in addition to return valueZbigniew Jędrzejewski-Szmek
All callers look at the return value anyway.
2015-03-19Allow systemd-tmpfiles to set the file/directory attributesGoffredo Baroncelli
Allow systemd-tmpfiles to set the file/directory attributes, like chattr(1) does. Two more commands are added: 'H' and 'h' to set the attributes, recursively and not.
2015-03-19Add change_attr_fd()Goffredo Baroncelli
Add change_attr_fd() function to modify the file/directory attribute.
2015-03-19fsck: use %zu for size_tThomas Hindoe Paaboel Andersen
cur and max were changed to size_t in ac6e2f0dfc2e800f01c79ecea2b811914110a7b9 update the format accordingly.
2015-03-19strv: return NULL from strv_free()David Herrmann
We always return NULL/invalid-object from destructors, fix strv_free() to do the same.
2015-03-19bootctl: drop redundant parse_argv()David Herrmann
We already call parse_argv() from main(), don't call it here again.
2015-03-18libudev: private - introduce udev_device_new_from_synthetic_event()Tom Gundersen
This allows set_action(), read_uevent_file() and read_db() to be made internal to libudev.
2015-03-16core/namespace: fix path sortingMichal Schmidt
The comparison function we use for qsorting paths is overly indifferent. Consider these 3 paths for sorting: /foo /bar /foo/foo qsort() may compare: "/foo" with "/bar" => 0, indifference "/bar" with "/foo/foo" => 0, indifference and assume transitively that "/foo" and "/foo/foo" are also indifferent. But this is wrong, we want "/foo" sorted before "/foo/foo". The comparison function must be transitive. Use path_compare(), which behaves properly. Fixes: https://bugzilla.redhat.com/show_bug.cgi?id=1184016
2015-03-16shared: add path_compare(), an ordering path comparisonMichal Schmidt
... and make path_equal() a simple wrapper around it.

2015-03-16shared - reinstate plymouth_running()Tom Gundersen
This will be used by fsckd. This reverts part of 031886edfc6e96ab778c241035a8d00fb0de99d3.
2015-03-16core: Remove explicit Plymouth integrationJasper St. Pierre
Even if plymouth is running, it might have not displayed the splash yet, so we'll see a few lines on fbcon when we should have otherwise had nothing. Plymouth integration was added to systemd in commit 6faa11140bf776cdaeb8d22d01816e6e48296971. That same day, Plymouth got systemd integration [0]. As such, the Plymouth integration has always been obsolete, and was probably only for older Plymouth's. But I can't imagine anybody running a Plymouth from 2011 with a systemd from 2015. Remove the Plymouth/systemd integration, and let Plymouth's code tell systemd to print the details.

2015-03-16core: don't change removed devices to state "tentative"Martin Pitt
Commit 628c89c introduced the "tentative" device state, which caused devices to go from "plugged" to "tentative" on a remove uevent. This breaks the cleanup of stale mounts (see commit 3b48ce4), as that only applies to "dead" devices. The "tentative" state only really makes sense on adding a device when we don't know where it was coming from (i. e. not from udev). But when we get a device removal from udev we definitively know that it's gone, so change the device state back to "dead" as before 628c89c.
2015-03-15vconsole-setup: check error of child processLucas De Marchi
If we don't check the error of the child process, systemd-vconsole-setup would exit with 0 even if it could not really setup the console. For a simple test, move loadkeys elsewhere and execute systemd-vconsole-setup: [root@localhost ~]# strace -f -e execve /usr/lib/systemd/systemd-vconsole-setup execve("/usr/lib/systemd/systemd-vconsole-setup", ["/usr/lib/systemd/systemd-vconsol"...], [/* 15 vars */]) = 0 Process 171 attached [pid 171] execve("/usr/bin/loadkeys", ["/usr/bin/loadkeys", "-q", "-C", "/dev/tty0", "br-abnt2"], [/* 15 vars */]) = -1 ENOENT (No such file or directory) [pid 171] +++ exited with 1 +++ --- SIGCHLD {si_signo=SIGCHLD, si_code=CLD_EXITED, si_pid=171, si_uid=0, si_status=1, si_utime=0, si_stime=0} --- +++ exited with 0 +++ Note that loadkeys returned 1 while systemd-vconsole-setup return 0. Since the font and keyboard setup are already serialized, refactor the code a little bit so the functions do the wait by themselves. One change in behavior in this patch is that we don't return early, but we do try to setup the keyboard even if the font load failed.
2015-03-15network: add UseNTP DHCP optionMichael Marineau
Despite having the internal logic in place to enable/disable using NTP servers provided by DHCP the network config didn't expose the option.

2015-03-14journald: add syslog fields for audit messagesZbigniew Jędrzejewski-Szmek
Audit messages would be displayed as "unknown[1]". Also specify AUTH as facility... This seems to be the closest match (/* security/authorization messages */).

2015-03-14cryptsetup-generator: remove warning about crypttab access modeZbigniew Jędrzejewski-Szmek
This file contains no privileged data — just names of devices to decrypt and files containing keys. On a running system most of this can be inferred from the device tree anyway.
2015-03-14udev: downgrade "has devpath" and "filled with db file" messagesZbigniew Jędrzejewski-Szmek
Udev debug messages have to be significantly overhauled... For now just downgrade those two. They are responsible for approximately 25% of debug output during boot and are rather useless.

Quotes are useful when the string can contain spaces or be otherwise confusing. Not possible with those two.
2015-03-14sysv-generator: initialize LookupPaths just onceZbigniew Jędrzejewski-Szmek
With debugging on, sysv-generator would print the full set of lookup paths for *every* sysv script. While at it, pass LookupPaths as a pointer in sysv-generator, and constify it everywhere.
