2015-11-16siphash24: let siphash24_finalize() and siphash24() return the result directlyDaniel Mack
Rather than passing a pointer to return the result, return it directly from the function calls. Also, return the result in native endianess, and let the callers care about the conversion. For hash tables and bloom filters, we don't care, but in order to keep MAC addresses and DHCP client IDs stable, we explicitly convert to LE.

Sort the includes accoding to the new coding style.
2015-11-16siphash24: change result argument to uint64_tMartin Pitt
Change the "out" parameter from uint8_t[8] to uint64_t. On architectures which enforce pointer alignment this fixes crashes when we previously cast an unaligned array to uint64_t*, and on others this should at least improve performance as the compiler now aligns these properly. This also simplifies the code in most cases by getting rid of typecasts. The only place which we can't change is struct duid's en.id, as that is _packed_ and public API, so we can't enforce alignment of the "id" field and have to use memcpy instead.

2015-10-24util-lib: split our string related calls from util.[ch] into its own file ↵Lennart Poettering
string-util.[ch] There are more than enough calls doing string manipulations to deserve its own files, hence do something about it. This patch also sorts the #include blocks of all files that needed to be updated, according to the sorting suggestions from CODING_STYLE. Since pretty much every file needs our string manipulation functions this effectively means that most files have sorted #include blocks now. Also touches a few unrelated include files.
2015-10-22sd-ndisc: rename API from sd-icmp6-ndTom Gundersen
2015-10-22sd-icmp6-nd: rename files to sd-ndiscTom Gundersen
The actual code rename will follow. The reason for the change of name is to make it simpler and more uniform with how we name other libraries (we don't include the underlying protocol). The new name also matches the naming in the kernel (which is particularly relevent here as we expect to let the kernel do some parts of the protocol and we do others).
2015-09-30tree-wide: clean up log_syntax() usageLennart Poettering
- Rely everywhere that we use abs() on the error code passed in anyway, thus don't need to explicitly negate what we pass in - Never attach synthetic error number information to log messages. Only log about errors we *receive* with the error number we got there, don't log any synthetic error, that don#t even propagate, but just eat up. - Be more careful with attaching exactly the error we get, instead of errno or unrelated errors randomly. - Fix one occasion where the error number and line number got swapped. - Make sure we never tape over OOM issues, or inability to resolve specifiers

Prefix all exported constants by SD_ICMP6_ND_* to avoid any namespacing conflicts.
2015-08-26dhcp: generic data should be void*, not uint8_t*Lennart Poettering
If we handly arbitrary data we should use "void*" pointers, not "uint8_t*", how go intended C to be used.

2015-02-16network-internal: chain matches with AND in net_match_config()Zbigniew Jędrzejewski-Szmek
The test would treat the first non-empty set of matches in match_paths, match_drivers, match_types, match_names as definitive (essentially chaining them with OR). Make those tests instead match like other tests and require all to pass if the set of patterns is nonempty.

2015-02-11network-internal: fix inverted matchingTom Gundersen
This fixes the test-suite again.
2015-02-10net: support globbing and disjunction in Match logicTom Gundersen
Match{Name,OrginalName,Type,Driver,Path} can now take a space-separated glob of matches.

inet_ntoa() uses a static buffer, so you can't call it twice in the same fprintf() call.
2014-12-05net_setup/networkd: warn if matching is done on possibly unstable ifnameTom Gundersen
2014-12-04udev: net_setup - allow matching on OriginalName=Tom Gundersen
This has been requested repeatedly, so let's give it a go. We explicitly do not allow matching on names that have already been changed (from a previous udev run, or otherwise), and matching on unpredictable names (ethX) is discouraged (but not currently disallowed). We also currently allow: [Match] Name=veth0 [Link] Name=my-name0 SomeOtherSetting=true Which means that the link file will be applied the first time it is invoked, but not on subsequent invocations, which may be surprising.
2014-11-06shared: rename condition-util.[ch] to condition.[ch]Lennart Poettering
Now that we only have one file with condition implementations around, we can drop the -util suffix and simplify things a bit.
2014-11-06core: get rid of condition.c and move the remaining call into util.cLennart Poettering
That way only one file with condition code remaining, in src/shared/, rather than src/core/. Next step: dropping the "-util" suffix from condition-util.[ch].
2014-11-06condition: internalize condition test functionsLennart Poettering
Also, implement the negation check inside of condition_test() instead of individually in each test function.
2014-09-16libsystemd-network: avoid double-free in error caseAndreas Henriksson
Don't manually free 'n' in error path as it's already tagged _cleanup_free_ and will be freed once it goes out of scope, leading to double-free in this case. Found with coverity. Fixes: CID#1237786
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.
2014-07-31Reject 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
2014-07-23networkd: merge DNS and NTP entries when exportingTom Gundersen
In the state files, do not distinguish where the various entries came from (static or DHCP), but include them all in the same list.
2014-07-18change type for address family to "int"Lennart Poettering
Let's settle on a single type for all address family values, even if UNIX is very inconsitent on the precise type otherwise. Given that socket() is the primary entrypoint for the sockets API, and that uses "int", and "int" is relatively simple and generic, we settle on "int" for this.
2014-07-17sd-network: remove redundant array size parameter from functions that return ↵Lennart Poettering
arrays As long as the number of array entries is relatively small it's nicer to simply return the number of entries directly, instead of using a size_t* return parameter for it.

2014-06-17networkd: veth - fix memleakTom Gundersen
2014-06-03networkd: drop CAP_SYS_MODULETom Gundersen
Rely on modules being built-in or autoloaded on-demand. As networkd is a network facing service, we want to limits its capabilities, as much as possible. Also, we may not have CAP_SYS_MODULE in a container, and we want networkd to work the same there. Module autoloading does not always work, but should be fixed by the kernel patch f98f89a0104454f35a: 'net: tunnels - enable module autoloading', which is currently in net-next and which people may consider backporting if they want tunneling support without compiling in the modules. Early adopters may also use a module-load.d snippet and order systemd-modules-load.service before networkd to force the module loading of tunneling modules. This sholud fix the various build issues people have reported.

This patch enables basic ipip tunnel support. It works with kernel module ipip example conf: file: ipip.netdev [NetDev] Name=ipip-tun Kind=ipip MTUBytes=1480 [Tunnel] Local=192.168.223.238 Remote=192.169.224.239 TTL=64 file: ipip.network [Match] Name=em1 [Network] Tunnel=ipip-tun [tomegun: - drop unused variable - take ref when enslaving]
2014-05-07sd-network: expose both admin and operational state directlyTom Gundersen
Also add a call to check if a link is loopback, as this should commonly be ignored.
2014-04-24networkd-wait-online: improve interoptability and enable by defaultTom Gundersen
To make sure we don't delay boot on systems where (some) network links are managed by someone else we don't block if something else has successfully brought up a link. We will still block until all links we are aware of that are managed by networkd have been configured, but if no such links exist, and someone else have configured a link sufficiently that it has a carrier, it may be that the link is ready so we should no longer block. Note that in all likelyhood the link is not ready (no addresses/routes configured), so whatever network managment daemon configured it should provide a similar wait-online service to block network-online.target until it is ready. The aim is to block as long as we know networking is not fully configured, but no longer. This will allow systemd-networkd-wait-online.service to be enabled on any system, even if we don't know whether networkd is the main/only network manager. Even in the case networking is fully configured by networkd, the default behavior may not be sufficient: if two links need to be configured, but the first is fully configured before the second one appears we will assume the network is up. To work around that, we allow specifying specific devices to wait for before considering the network up. This unit is enabled by default, just like systemd-networkd, but will only be pulled in if anyone pulls in network-online.target.
2014-04-19networkd: tie links to rtnl rather than udevTom Gundersen
This essentially swaps the roles of rtnl and udev in networkd. After this change libudev is only used for waiting for udev to initialize devices and to get udev-specific information needed for some [Match] attributes. This in particular simplifies the code in containers where udev is not really useful, but also simplifies things and reduces round-trips in the non-container case.

2014-03-21libsystemd-network: move network-utils from src/sharedTom Gundersen
This does not belong in shared as it is mostly a detail of our networking subsystem. Moreover, now we can use libudev here, which will simplify things.
