2014-08-18memfd: internalize functions, drop sd_memfd typeDaniel Mack
Remove the sd_ prefix from internal functions and get rid of the sd_memfd type. As a memfd is now just a native file descriptor, we can get rid of our own wrapper type, and also use close() and dup() on them directly.
2014-08-18memfd: use _cleanup_ if applicableDavid Herrmann
We now have a sd_memfd_freep helper, use it if applicable.
2014-08-18memfd: map unsealed files as MAP_SHAREDDavid Herrmann
We need to map sealed files as MAP_PRIVATE so far as the kernel treats MAP_SHARED as writable mapping (you can run mprotect(PROT_WRITE) at any time on those). However, unsealed files must be mapped as MAP_SHARED. Otherwise, we never end up writing to the real file.
2014-08-18memfd: disallow importing memfds without sealingDavid Herrmann
We use memfds for sealing. Lets not bother with memfds created without MFD_ALLOW_SEALING for now. They're equivalent to random shmem files, so don't bother treating them as sealable memfds.
2014-08-18memfd: don't open kdbus for memfdDavid Herrmann
No reason to open /dev/kdbus/control if we want memfds. memfd_create() is always available.
2014-08-18memfd: internalize headerDavid Herrmann
Fix the memfd.h header to use handy features like #pragma, cleanup-funcs and util.h. Also drop the EXTERN-C macros.
2014-08-18memfd: fix memfd_create() syscall wrapperDaniel Mack
Unlike earlier versions, the syscall only takes 2 arguments in its final version, not 3.
2014-08-18memfd: move code from public library to src/sharedDaniel Mack
Don't expose generic kernel API via libsystemd, but keep the code internal for our own usage.
2014-08-17kdbus: switch over to generic memfd implementation (ABI+API break)Daniel Mack
2014-08-16sd-bus,log: remove unused variablesThomas Hindoe Paaboel Andersen
2014-08-15main,log: parse the log related kernel command line parameters at one place ↵Lennart Poettering
only, and for all tools Previously, we ended up parsing some of them three times: in main.c when processing the kernel cmdline, in main.c when processing the process cmdline (only for containers), and in log.c again. Let's streamline this, and only parse them in log.c In PID 1 also make sure we parse "quiet" first, and then override this with the more specific checks in log.c
2014-08-15main: minor code modernization for initializing the consoleLennart Poettering
2014-08-15macro: add CONST_MAX() macroDavid Herrmann
The CONST_MAX() macro is similar to MAX(), but verifies that both arguments have the same type and are constant expressions. Furthermore, the result of CONST_MAX() is again a constant-expression. CONST_MAX() avoids any statement-expressions and other non-trivial expression-types. This avoids rather arbitrary restrictions in both GCC and LLVM, which both either fail with statement-expressions inside type-declarations or statement-expressions inside static-const initializations. If anybody knows how to circumvent this, please feel free to unify CONST_MAX() and MAX().
2014-08-15macro: const'ify MIN/MAX/... macrosDavid Herrmann
We must add 'const' to local variables in statement-expressions to guarantee that the macros can produce constant-expressions if given such. GCC seems to ignore this, but LLVM/clang requires it (understandably).
2014-08-15util: make is_localhost() check for 'localdomain' too, so that we can use it ↵Lennart Poettering
for both validating domains and host names
2014-08-15util: never use ether_ntoa(), since it formats with %x, not %02x, which ↵Lennart Poettering
makes ethernet addresses look funny
2014-08-15cgroup: never try to create files in cgroupfs, only open them for writingLennart Poettering
This should have the benefit that cg_set_attribute() returns ENOENT instead of EACCESS when we use it for non-existing attributes.

2014-08-13util: allow strappenda to take any number of argsDave Reisner
This makes strappenda3 redundant, so we remove its usage and definition. Add a few tests along the way for sanity.
2014-08-14timer: order OnCalendar units after timer-sync.target if DefaultDependencies=noTobias Geerinckx-Rice
Avoids triggering timers prematurely on systems with significantly inaccurate clocks, or some embedded platforms that lack one entirely.
2014-08-13resolved: skip IPv6 LLMNR if IPv6 is not availableLennart Poettering
2014-08-12timesyncd: move the generic sockaddr_equal() call to socket-util.hLennart Poettering
2014-08-12networkd: expose a global list of DNS and NTP servers in the state fileLennart Poettering
2014-08-12networkd: add minimal client tool "networkd" to query network statusLennart Poettering
In the long run this should become a full fledged client to networkd (but not before networkd learns bus support). For now, just pull interesting data out of networkd, udev, and rtnl and present it to the user, in a simple but useful output.
2014-08-11networkd: monopolize in_addr utility functions in shared/in-addr-util.hLennart Poettering
Primarily, this means we get rid of net_parse_inaddr(), and replace it everywhere with in_addr_from_string() and in_addr_from_string_auto(). These functions do not clobber the callers arguments on failure, which is more close to our usual coding style.
2014-08-11log: never ever log to syslog from PID 1, log to the journal againLennart Poettering
We don't support journal-less systems anyway, so let's avoid the confusion.
2014-08-11fix a couple of more lazy "return -1"Lennart Poettering
Fix should strictly follow the rule to return negative errno-style error codes from functions, hence let's fix more "return -1"-style lazinesses.

2014-08-08Added arch tuple for PPC64LEHarald Hoyer
Thanks to Brent Baude <bbaude@redhat.com>, who checked with the debian guys, that this is correct and provided the patch.
2014-08-08udev: link_setup - respect kernel name assign policyTom Gundersen
Newer kernels export meta-information about the origin of an ifname. Respect this from the ifname rename logic. We do not rename any interfaces that was originally named by userspace, nor once which have already been renamed from userspace. Moreover, we optionally do not (the default) rename interfaces which the kernel claims to have named in a predictable way.

2014-08-03util.h: include missing.h, for struct file_handleSimon McVittie
This breaks udev-builtin-btrfs.c, which reinvents some of missing.h, so use missing.h there too. [zj: removed #include "config.h" and wrapped #include <linux/btrfs.h> in ifdef HAVE_LINUX_BTRFS_H as discussed on the mailing list.]
2014-08-01missing: add missing bonding definitionsLennart Poettering
2014-08-01resolved: read the system /etc/resolv.conf unless we wrote it ourselvesLennart Poettering
This way we integrate nicely with foreign network management stacks, such as NM.

2014-07-31Always prefer our headers to system headersZbigniew Jędrzejewski-Szmek
In practice this shouldn't make much difference, but sometimes our headers might be newer, and we want to test them.
2014-07-31core/load-fragment.c: correct argument sign and split up long linesZbigniew Jędrzejewski-Szmek
With everything on one line they are just harder to read.
2014-07-31Properly report invalid quoted stringsZbigniew Jędrzejewski-Szmek
$ systemd-analyze verify trailing-g.service [./trailing-g.service:2] Trailing garbage, ignoring. trailing-g.service lacks ExecStart setting. Refusing. Error: org.freedesktop.systemd1.LoadFailed: Unit trailing-g.service failed to load: Invalid argument. Failed to create trailing-g.service/start: Invalid argument
2014-07-31Reject invalid quoted stringsZbigniew Jędrzejewski-Szmek
String which ended in an unfinished quote were accepted, potentially with bad memory accesses. Reject anything which ends in a unfished quote, or contains non-whitespace characters right after the closing quote. _FOREACH_WORD now returns the invalid character in *state. But this return value is not checked anywhere yet. Also, make 'word' and 'state' variables const pointers, and rename 'w' to 'word' in various places. Things are easier to read if the same name is used consistently. mbiebl_> am I correct that something like this doesn't work mbiebl_> ExecStart=/usr/bin/encfs --extpass='/bin/systemd-ask-passwd "Unlock EncFS"' mbiebl_> systemd seems to strip of the quotes mbiebl_> systemctl status shows mbiebl_> ExecStart=/usr/bin/encfs --extpass='/bin/systemd-ask-password Unlock EncFS $RootDir $MountPoint mbiebl_> which is pretty weird

Name defending is still missing.
2014-07-29time-util: add and use USEC/NSEC_INFINIYKay Sievers
2014-07-27parse_boolean: require exact matchesAnsgar Burchardt
Require exact matches in all cases instead of treating strings starting with 't' ('f') as true (false). This is required for config_parse_protect_system to parse ProtectSystem=full correctly: it uses parse_boolean and only tries a more specific parsing function if that did not return a valid result. Thus "full" was treated as "false" before.
2014-07-27core: only set the kernel's timezone when the RTC runs in local timeKay Sievers
We can not reliably manage any notion of local time. Every daylight saving time change or time zone change by traveling will make the time jump, and the local time might jump backwards which creates unsolvable problems with file timestamps. We will no longer tell the kernel our local time zone and leave everything set to UTC. This will effectively turn FAT timestamps into UTC timestamps. If and only if the machine is configured to read the RTC in local time mode, the kernel's time zone will be configured, but systemd-timesysnc will disable the kernel's system time to RTC syncing. In this mode, the RTC will not be managed, and external tools like Windows bootups are expected to manage the RTC's time. https://bugs.freedesktop.org/show_bug.cgi?id=81538
