2015-01-12network-intenal: user _cleanup_ macro in parse_ifnameTom Gundersen
2014-12-09libsystemd-network: fix writing of routes in dhcp lease fileDan Winship
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.

strndup need to be chcked
2014-06-29Add support for DHCP static route optionsEugene Yakubovich
This adds support for DHCP options 33 and 121: Static Route and Classless Static Route. To enable this feature, set UseRoutes=true in .network file. Returned routes are added to the routing table.
2014-06-19network-internal: split out net_get_name()Tom Gundersen
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.
2014-05-19sd-dhcp-lease: move in_addr (de)serialization to shared network codeTom Gundersen
2014-05-12networkd: manager - don't leak kmod contextTom Gundersen
Also, keep the kmod_new internal to networkd-manager.c
2014-05-12networkd: introduce ipip tunnelSusant Sahani
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.
