* network: unify config_parse_wireguard_public_key() and ↵Yu Watanabe2020-09-103-40/+12
| | | | config_parse_wireguard_preshared_key()
* network: don't fail on various config parse errorsLennart Poettering2020-09-092-8/+14
| | | | | We typically don't fail on config parse errors (to maximize compat), let's not do this in these cases either.
* tree-wide: prefer AF_xyz over PF_xyzLennart Poettering2020-09-091-1/+1
| | | | | | This really doesn't matter given that AF_xyz and PF_xyz are equivalent in all ways, but we almost always use AF_xyz, hence stick to it universally and convert the remaining PF_ to AF_
* tree-wide: define iterator inside of the macroZbigniew Jędrzejewski-Szmek2020-09-085-20/+12

* tree-wide: use READ_FULL_FILE_CONNECT_SOCKET at various placesLennart Poettering2020-07-212-2/+8
| | | | | | | | | | | Let's use the new flag wherever we read key material/passphrases/hashes off disk, so that people can plug in their own IPC service as backend if they like, easily. (My main goal was actually to support this for crypttab key files — i.e. that you can specify AF_UNIX sockets as third column in crypttab — but that's harder to implement, since the keys are read via libcryptsetup's API, not ours.)

* network: add support for MACVLAN source modeAlvin Šipraga2020-07-083-0/+44
| | | | | | | | | | | | | | | | | | | | | | | Add support for creating a MACVLAN interface in "source" mode by specifying Mode=source in the [MACVLAN] section of a .netdev file. A list of allowed MAC addresses for the corresponding MACVLAN can also be specified with the SourceMACAddress= option of the [MACVLAN] section. An example .netdev file: [NetDev] Name=macvlan0 Kind=macvlan MACAddress=02:DE:AD:BE:EF:00 [MACVLAN] Mode=source SourceMACAddress=02:AB:AB:AB:AB:01 02:CD:CD:CD:CD:01 SourceMACAddress=02:EF:EF:EF:EF:01 The same keys can also be specified in [MACVTAP] for MACVTAP kinds of interfaces, with the same semantics.

* netdev/wireguard: do not invalidate peer on invalid syntaxZbigniew Jędrzejewski-Szmek2020-06-221-16/+9
| | | | | | | We would say "ignoring", but invalidate the peer anyway. Let's only do that if we modified the peer irreperably. Also add comments explaining allocation handling.
* tree-wide: use set_ensure_put()Zbigniew Jędrzejewski-Szmek2020-06-221-14/+3
| | | | | | | | | Patch contains a coccinelle script, but it only works in some cases. Many parts were converted by hand. Note: I did not fix errors in return value handing. This will be done separate to keep the patch comprehensible. No functional change is intended in this patch.
* conf-parser: return mtime in config_parse() and friendsLennart Poettering2020-06-021-8/+13
| | | | | | | | | | | | | This is a follow-up for 9f83091e3cceb646a66fa9df89de6d9a77c21d86. Instead of reading the mtime off the configuration files after reading, let's do so before reading, but with the fd we read the data from. This is not only cleaner (as it allows us to save one stat()), but also has the benefit that we'll detect changes that happen while we read the files. This also reworks unit file drop-ins to use the common code for determining drop-in mtime, instead of reading system clock for that.
* network: also read mtime of drop-in configsYu Watanabe2020-06-011-2/+2
| | | | Fixes #15521.

* | network: introduce ifb (Intermediate Functional Block)Susant Sahani2019-12-074-0/+28
| | | | | | | | | | | | | | | | | | | | | | | | Intermediate Functional Block The Intermediate Functional Block (ifb) pseudo network interface acts as a QoS concentrator for multiple different sources of traffic. Packets from or to other interfaces have to be redirected to it using the mirred action in order to be handled, regularly routed traffic will be dropped. This way, a single stack of qdiscs, classes and filters can be shared between multiple interfaces. Here's a simple example to feed incoming traffic from multiple interfaces through a Stochastic Fairness Queue (sfq): (1) # modprobe ifb (2) # ip link set ifb0 up (3) # tc qdisc add dev ifb0 root sfq
