For example, [when](https://gitlab.freedesktop.org/NetworkManager/NetworkManager/-/blob/6b64fac06d2f6e0d9fa530ebb1ab28d53a1c5d03/src/core/dhcp/nm-dhcp-nettools.c#L563) + we receive a DHCP lease, we construct a NMIP4Config object with the addresses, DNS settings, + and so on.

It's a simple object with a clear API that + abstracts most of the complexity of handling DHCP. But still, NMDevice + needs to drive the DHCP client instance. Meaning, it needs to create (start) and stop + them and hook up signals for changes (new lease) and timeout. This is mostly + fine and unavoidable. The point is that while specific tasks are well abstracted + (like the details of DHCP), there is still some state in NMDevice that is related + to manage these tasks. DHCP is one of many such tasks, like also + link local addresses, SLAAC or LLDP. + This leads to the increased complexity of NMDevice, which manages a large variety + of such tasks. + +### Problems: + +1. first the sheer code size of [nm-device.c](https://gitlab.freedesktop.org/NetworkManager/NetworkManager/-/blob/6b64fac06d2f6e0d9fa530ebb1ab28d53a1c5d03/src/core/devices/nm-device.c#L19030). + It's hard to understand and maintain, and this results in misbehaviours. Also, features that should be easy to implement + are not. Also, there are inefficiencies that are hard to fix. + +2. NMDevice and NMIP4Config are both exported on D-Bus while having other responsibilities. + Being subclasses of NMDBusObject, they are glued to the D-Bus API. For example, NMIP4Config is + also used for other purposes (for tracking IP configuration internally). + +3. NMDevice simply does too much. IP configuration should be a separate, encapsulated + API to make allow NMDevice to be smaller and the IP configuration part better + testable, understandable and smaller too. + +4. in the current model, NMDevice can be related to zero, one or two ifindexes. For example, + for ethernet devices, there is commonly only one actual netdev device (and one ifindex). + For OVS devices, there is no ifindex. For NMDeviceModem or NMDeviceBluetooth there is + a NMDevice instance that has initially no ifindex (it represents the tty serial port + or the bluetooth device) but during activation it gets and ip ifindex. With PPPoE, + the ethernet device can even have two ifindexes (one for the underlying ethernet and + one for the PPP device). That is all utterly confusing, inconsistent and limited. + For example, not all interfaces you see in `ip link` can be found in the D-Bus API. + The D-Bus API also does not give access to the ifindex (which is the real identifier + for a netdev devices). It only exposes the IpInterface name. That should be improved too, + but even such seemingly simple things are not done for years, because it's not trivially + clear what the right ifindex is. + Also a device instance on D-Bus significantly changes its meaning when it activates/deactivates + and it starts/stops being responsible for an ifindex. + In the future there should be devices that represent exactly one netdev device (an ifindex) + and devices that don't have an ifindex. That is follow up work and hinted by + [rhbz#1066703](https://bugzilla.redhat.com/show_bug.cgi?id=1066703). But simplifying + the IP configuration is a requisite before addressing that rework. + With this we will have controller and controlled devices. That means, a controller devices + (that for example represents a bluetooth device) will need to configure IP address on the + controlled IP device. That would be doable by injecting the IP config on that device, + but as the device already does so much, it would be better if this would be a separate + IP configuration manager for that ifindex. + +5. NMIP4Config exports properties on D-Bus like [AddressData](https://gitlab.freedesktop.org/NetworkManager/NetworkManager/-/blob/6b64fac06d2f6e0d9fa530ebb1ab28d53a1c5d03/introspection/org.freedesktop.NetworkManager.IP4Config.xml#L26). + which are the currently configured IP addresses. These should be directly obtained + from the NMPlatform cache, which contains the correct list of addresses as kernel + exposes them via rtnetlink. Instead, whenever there are changes in platform we + [generate](https://gitlab.freedesktop.org/NetworkManager/NetworkManager/-/blob/6b64fac06d2f6e0d9fa530ebb1ab28d53a1c5d03/src/core/devices/nm-device.c#L14223) + an NMIP4Config instance, then we merge, intersect and subtract this captured information + with the IP configs we want to configure. Finally we merge them together again + and sync the result to platform. This is bad, wrong and inefficient. + We must not mix "what is configured" with "what we want to configure". The current + approach also re-generates these IP config instance whenever something in platform changes. + That does not scale. If we have any hope to handle thousands of routes, this needs to change. + +6. The NMIP4Config objects are mutable, and they are heavily mutated. When we create an NMIP4Config + instance that represent a DHCP lease, we will [subtract](https://gitlab.freedesktop.org/NetworkManager/NetworkManager/-/blob/6b64fac06d2f6e0d9fa530ebb1ab28d53a1c5d03/src/core/devices/nm-device.c#L14236) + addresses that were externally removed. That is wrong, because during a reapply we + will need to know these addresses again. The solution for that is not to mutate this + data, but track whether IP addresses are removed separately. + +7. NMDevice also does ACD, but it can only do it for addresses received via DHCP. + It implicitly also does ACD for IPv4LL, but that is via using the n_ipv4ll library. + It would be good to have an option that we can configure IPv4LL for any address. + Also, if you manually configure an address like 192.168.2.5 (for which we don't do + ACD) and the same address is obtained via DHCP, then doing ACD for the address is wrong. + There needs to be link-wide view of the addresses, and not only looking at individual + addresses when deciding to do ACD. + +8. As IP configuration is done by NMDevice, VPN connections have limited capabilities + in this regard. + When a VPN has IP addresses, then it injects them into NMDevice by + [providing](https://gitlab.freedesktop.org/NetworkManager/NetworkManager/-/blob/6b64fac06d2f6e0d9fa530ebb1ab28d53a1c5d03/src/core/devices/nm-device.c#L13696) + an NMIP4Config. However, that means VPNs cannot do DHCP or IPv4LL, because it can + only inject known configuration. That would be very useful for example with a tap + device with openvpn. The real problem here is that NMVpnConnection are + treated special, when they should be more like devices. That should be reworked in the future, + by reworking VPN plugins. Regardless, having IP configuration handled by NMDevice is limiting. + +9. NetworkManager currently supports `ipv4.method` which can be "manual", "disabled" or + "auto". This scheme does not allow for example to enable IPv4LL together with DHCPv4. + As a special case, you can configure `ipv4.method=auto` together with static + addresses in `ipv4.addresses`, so combining DHCP and static addressing works. But in general, + this scheme is limited. In the future we should have more flexible schemes, where + addressing methods can be independently enabled or disabled. Also, we currently + have `ipv4.may-fail`, but that is limited as well. For example, + `ipv4.may-fail=yes` and `ipv6.may-fail=yes` still means that at least one of the + address families must succeed. That makes sense for certain use cases, but it + means, you cannot have truly best-effort, opportunistic DHCP with this way. + As workaround for that there is `ipv4.dhcp-timeout=infinity`. In + general it is not only useful to enable methods independently, we also configure + independently whether they are required or optional (and possibly, that they are optional + but at least one of several optional methods must succeed). Anyway. The point + is there is a need to make IP configuration more flexible. Currently it is not. + Such a seemingly simple extension would be surprisingly difficult to implement + because [the code](https://gitlab.freedesktop.org/NetworkManager/NetworkManager/-/blob/6b64fac06d2f6e0d9fa530ebb1ab28d53a1c5d03/src/core/devices/nm-device.c#L6616) is + all over the place. The way how NMDevice tracks the overall activation state is + hard to understand. This should be improved and possibly could be improved in a + smaller refactoring effort. But instead of a smaller effort, we will use the big hammer + with L3Cfg rework. + +10. There are two classes NMIP4Config and NMIP6Config. Handling both address families is + commonly similar, so there is lot of similar code in both. They should be unified + so that similar code can handle both address families. + + +Solution and Future +------------------- + +NML3Cfg work is supposed to simplify some part of NMDevice: the part related to +IP configuration. This is a huge rework of a core part of NetworkManager. Arguably, +some parts maybe could be done more evolutionary, but the fundamental problems require +to rip out NMIP4Config and replace it by something better. Doing that is a large rework +that changes NMDevice heavily. That is also the opportunity to get the smaller issues +right. + +There is already a new class [NML3Cfg](https://gitlab.freedesktop.org/NetworkManager/NetworkManager/-/blob/6b64fac06d2f6e0d9fa530ebb1ab28d53a1c5d03/src/core/nm-l3cfg.h#L141) +(currently unused). An NML3Cfg instance is responsible for handling IP configuration +of an ifindex. Consequently, we can ask NMNetns to [get](https://gitlab.freedesktop.org/NetworkManager/NetworkManager/-/blob/6b64fac06d2f6e0d9fa530ebb1ab28d53a1c5d03/src/core/nm-netns.c#L142) +(or create) a NML3Cfg instance for an ifindex. +The idea is that there can be multiple users (NMDevice and NMVpnConnection and future controller devices) +that use the same NML3Cfg instance. Especially with a future rework of NMDevice where +a NMDevice only manages one ifindex (or none), there is a need that multiple +devices manage the IP configuration on the same device. Independent users can cooperate +to configure IP configuration on the same device. Already now with Libreswan VPN, where the VPN "injects" +its NMIP4Config in NMDevice. Or with PPPoE, where the NMDeviceEthernet is both about IP configuration +for the PPPoE device. + +There is also a new class [NML3ConfigData](https://gitlab.freedesktop.org/NetworkManager/NetworkManager/-/blob/6b64fac06d2f6e0d9fa530ebb1ab28d53a1c5d03/src/core/nm-l3-config-data.h). +This replaces some aspect of NMIP4Config/NMIP6Config. A NML3ConfigData object is immutable and has no real logic +(or state). It has some "logic", like comparing two NML3ConfigData instances, logging it, or merging two (immutable) +instances into a new instance. But as the class is immutable, that logic is rather simple. This class is +used to track information. As it's immutable, anybody who is interested can keep a reference +for it's own purpose. For example, NMDhcpClient will generate a NML3ConfigData with the information +of the lease. It may keep the reference, but it will also tell NMDevice about it. The NMDevice +will then itself tell NML3Cfg to accept this configuration. This works by calling +[add()/remove()](https://gitlab.freedesktop.org/NetworkManager/NetworkManager/-/blob/6b64fac06d2f6e0d9fa530ebb1ab28d53a1c5d03/src/core/nm-l3cfg.c#L2654). +One NML3ConfigData can also track both IPv4 and IPv6 information. It's a general set of IP related +configuration, that has some address specific properties. Those are then duplicated for both address +families and implemented in a way to minimize code duplication and encourage to treat them the same. +As this replaces an aspect of NMIP4Config, NMIP4Config can focus on it's other purpose: to expose data on D-Bus. + +What NML3Cfg then does, is to merge all NML3ConfigData, and "commit" it to platform. Thereby it knows +which addresses it configured the last time (if they no longer are to be configured, they must be removed). +This is done [here](https://gitlab.freedesktop.org/NetworkManager/NetworkManager/-/blob/6b64fac06d2f6e0d9fa530ebb1ab28d53a1c5d03/src/core/nm-l3cfg.c#L3442). + +As independent users should be able to cooperate, it is not appropriate that they call "commit". +Instead, they set a commit type ([here](https://gitlab.freedesktop.org/NetworkManager/NetworkManager/-/blob/6b64fac06d2f6e0d9fa530ebb1ab28d53a1c5d03/src/core/nm-l3cfg.c#L3476), +and whenever something changes, NML3Cfg knows the aggregated commit type. That is necessary +because when we activate a device, we may want to preserve the existing IP configuration (e.g. after +a restart of NetworkManager). During that time is the NML3Cfg instance set to a reduced commit +mode (ASSUME). + +NML3Cfg will also handle IPv4 ACD. Any user of NML3Cfg registers/unregisters NML3ConfigData instances +that should be configured. Thereby they also say whether ACD should be done for the IPv4 addresses. +NML3Cfg then keeps state for each IPv4 address, whether ACD should be performed, and whether the +address is ready to be configured. NML3Cfg does not do DHCP or similar. That is still the responsibility +of NMDevice to run a NMDhcpClient. But it does run ACD, because whether to perform ACD on an address +requires a holistic view of all addresses of that interface. For example, if you configure a static +IP address 192.168.2.5 (with ACD disabled) and you also get the same address via DHCP, then ACD should +not performed for that address (even if the user configured ACD with DHCP). Of course, that is a very +unlikely example. More likely is that NetworkManager is restarted and it leaves the addresses (that passed +ACD) configured. After restart, DHCP finds the same addresses and no new ACD should be performed. This shows +that the ACD state depends all the IP addresses on an interface, +and thus it's done by NML3Cfg. The API for this is very simple. Users enable/disable ACD during nm_l3cfg_add_config() +and receive events like [NM_L3_CONFIG_NOTIFY_TYPE_ACD_EVENT](https://gitlab.freedesktop.org/NetworkManager/NetworkManager/-/blob/6b64fac06d2f6e0d9fa530ebb1ab28d53a1c5d03/src/core/nm-l3cfg.c#L303). +Another advantage is that ACD now works for any kinds of addresses. Currently it only works for addresses +from DHCP and link local addresses. + +NML3Cfg does not implement or drive DHCP. However, as it already does ACD it gained it's own IPv4LL +"library": [NML3IPv4LL](https://gitlab.freedesktop.org/NetworkManager/NetworkManager/-/blob/6b64fac06d2f6e0d9fa530ebb1ab28d53a1c5d03/src/core/nm-l3cfg.c#L3624). +This will replace nettools' n-ipv4ll library, because that library also does ACD internally, while we want +to use the holistic view that NML3Cfg has. What this means, is that the user (NMDevice) +can request a NML3IPv4LL handle from the NML3Cfg instance, and it just does it with a simple API. +All the user might do is to enable/disable the handle and to react to signals (if it cares to find +out whether IPv4LL fails). + +The general parts of NML3Cfg are already implemented. It has unit tests and can be tested independently. +You might note that NML3Cfg is not trivial already, but the API that it provides is as simple as possible: +create immutable NML3ConfigData instance, and add/remove them. Optionally, handle the ACD events and +listen to some events. The complexity that NML3Cfg has, will lead in the same amount simplify NMDevice. + +What is missing is NMDevice using this new API. Instead of creating and tracking NMIP4Config instances, +it needs to track NML3ConfigData instances. In principle that sounds simple, in practice that changes +large part of "nm-device.c". + +Thereby also the state machine for NM_DEVICE_STATE will be improved. It's anyway a rewrite. This will lay the +groundwork for more flexible configuration of IP methods, with different failure modes (opportunistic or +mandatory). + +What then also should be easier, to combine IPv4LL with other addressing methods. In Windows AFAIK, if you +don't get a DHCP address it will configure a IPv4LL address. That is also what RFC suggests, but which we +currently don't support. + +In general, change the way how external IP addresses/routes are tracked. This merge, intersect, subtract +approach does not perform well. Currently we react on signals and it's hard to understand what happens +in response to that, or whether it's really the correct thing to do. See yourself starting from +[here](https://gitlab.freedesktop.org/NetworkManager/NetworkManager/-/blob/6b64fac06d2f6e0d9fa530ebb1ab28d53a1c5d03/src/core/devices/nm-device.c#L14214). + +### DHCP + +Currently, when NMDhcpClient receives a lease, it emits a signal with two things: the NMIP4Config +instance (containing addresses, routes, DNS settings and other information for later use), and a string +dictionary with the DHCP lease options (they are mainly used to expose them on D-Bus). The latter is +immutable (meaning, it's not changed afterwards). That does not significantly change with L3Cfg. The +difference is that instead of NMIP4Config a NML3ConfigData instance gets created. That instance then +references the (immutable) strdict. With that, any part of the code that has access to the NML3ConfigData, +also has access to the lease options. So instead of two separate +pieces of information, the result of a lease event will only be a NML3ConfigData instance (which internally +tracks the strdict with the DHCP lease options). + +Later, when NML3Cfg configures an interface, it takes all NML3ConfigData instances that were added to +it, and merges them. [Currently](https://gitlab.freedesktop.org/NetworkManager/NetworkManager/-/blob/6b64fac06d2f6e0d9fa530ebb1ab28d53a1c5d03/src/core/nm-l3-config-data.c#L2693), +the merged data will not contain the lease information, but it's probably not needed anyway. + +If it would be needed, the question is what happens if multiple lease informations are present +during the merge. Duplicate leases would not commonly happen, but in general, the merging algorithm +needs to take into account priorities and conflicting data. +That is done by users who call [add](https://gitlab.freedesktop.org/NetworkManager/NetworkManager/-/blob/6b64fac06d2f6e0d9fa530ebb1ab28d53a1c5d03/src/core/nm-l3cfg.c#L2658) +to provide a priority for the NML3ConfigData instance. +Later, the instances get sorted by priority and merging is smart to take that into account +([here](https://gitlab.freedesktop.org/NetworkManager/NetworkManager/-/blob/6b64fac06d2f6e0d9fa530ebb1ab28d53a1c5d03/src/core/nm-l3cfg.c#L2983)). + +Also, we currently inject the route-metric and table into the generated NMIP4Config. +Those settings come from the connection profiles and not from DHCP. We will avoid that +by allowing the routes in NML3ConfigData to be marked as metric\_any and table\_any. +That way,the NML3ConfigData is independent (and immutable) with respect to those settings. +The same happens for example with PPP, where the modem starts PPP, and currently the +route and metric needs to be passed several layers down. But worst, those settings +can change during reapply. Currently that means we need to hack NMIP4Config with +those changes. Later, we will only tell NML3Cfg to track the NML3ConfigData with +different settings. + +### DNS + +DNS information is currently set in the NMIP4Config instances. That happens for example with the DNS information +from a DHCP lease, but also with the static DNS settings from the connection profile. Later, the same information +will packed in NML3ConfigData. + +One nice difference is again the immutability. Currently, NMDnsManager keeps a reference to all relevant NMIP4Config instances, +but as they are mutable, it needs to [subscribe](https://gitlab.freedesktop.org/NetworkManager/NetworkManager/-/blob/6b64fac06d2f6e0d9fa530ebb1ab28d53a1c5d03/src/core/dns/nm-dns-manager.c#L275) +to changes. Later, when a NML3ConfigData instance "changes", it means it was +replaced by a different one and NMDnsManager needs to update its list of tracked NML3ConfigData. I find that +cleaner, because adding and removal to the list of NMIP4Config/NML3ConfigData happens anyway and needs to be handled. + + +Related Bugs +------------ + +* Main bug: + + - [rh#1868254](https://bugzilla.redhat.com/show_bug.cgi?id=1868254): + "refactor NetworkManager's IP configuration done by NMDevice" + +* Follow up but to improve model of devices: + + - [rh#1066703](https://bugzilla.redhat.com/show_bug.cgi?id=1066703): + "\[RFE\] Handle parent/child relationships more cleanly" + +* Flexible IP methods: + + - [rh#1791624](https://bugzilla.redhat.com/show_bug.cgi?id=1791624): + "NetworkManager must not remove used bridge" + +* Improving performance issues, this will lay ground work: + + - [rh#1847125](https://bugzilla.redhat.com/show_bug.cgi?id=1847125): + "\[RFE\] Improve 20% performance on creating 1000 bridge over 1000 VLANs" + + - [rh#1861527](https://bugzilla.redhat.com/show_bug.cgi?id=1861527): + "Excessive memory and CPU usage on a router with IPv6 BGP feed" + + - [rh#1753677](https://bugzilla.redhat.com/show_bug.cgi?id=1753677): + "High cpu usage while non-controlled interface is mangling tc filters" + diff --git a/src/core/README.next.ip-config.md b/src/core/README.next.ip-config.md new file mode 100644 index 0000000000..e5be74f133 --- /dev/null +++ b/src/core/README.next.ip-config.md @@ -0,0 +1,59 @@ +Rework `NMIP[46]Config` for `next` branch +========================================= + +The `next` branch is a large rework of internals, how IP configuration is done by `NMDevice`. + +Previously, there are two `GObject`s named `NMIP4Config` and `NMIP6Config`. These +serve different purposes: + +1) They are data containers that can track IP configuration. As such, `NMDevice` + and various parts (like `NMDhcpClient`) create them, pass them around and + mutate/merge them to track the IP configuration. + +2) They are also subclasses of `NMDBusObject` and exported on D-Bus as + `/org/freedesktop/NetworkManager/IP4Config/1`, etc. As such, see their + [D-Bus API](../../introspection/org.freedesktop.NetworkManager.IP4Config.xml) + (and [for IPv6](../../introspection/org.freedesktop.NetworkManager.IP6Config.xml)). + +`next` branch will replace use 1) with `NML3ConfigData`. `NML3ConfigData` are immutable +(sealable) data containers with little logic. This leaves `NMIP4Config` to only +implement 2). + +This needs to be reworked. + +* Now `NMIP4Config` and `NMIP6Config` are subclasses of `NMIPConfig`. The goal + is to treat IPv4/IPv6 similar and generically. Probably there should be very + little code in the subclasses left and most should move to the parent classes. + We still need separate GObject types though, because that is how `NMDBusObject`'s + glue code can handle different D-Bus paths. + +* Now `NML3Cfg` is a handle for the IP configuration parameters of a device (ifindex). + As `NMIPConfig` mostly is about exporting the current IP configuration, it probably + can get most of it from there (and by listening to signals to that). + +* Note that `NMDevice`, `NMActiveConnection` refer `NMIP[46]Config`s, and most + importantly, the respective D-Bus objects refer to them. As `NMVpnConnection` + (and "org.freedesktop.NetworkManager.VPN.Connection" interface) are modeled + as "subclasses" of `NMActiveConnection`, they also have one.

With `next` branch and `NML3Cfg` there is a clear distinction + between what NetworkManager wants to configure vs. what is actually configured. + I think for `NMDevice` and `NMActiveConnection`, the IP addresses on + "org.freedesktop.NetworkManager.IP4Config" should expose the IP addresses + that are actually in platform (`ip addr`). If there is a need to expose + additional information (like things that NetworkManager wanted to configure), + then this should be different/new API. + On the other hand, currently `NMVpnConnection`'s `NMIP4Config` only tracks the + IP addresses that come from the VPN plugin. So it's much more what it wants + to configure (from the VPN plugin), and not at all about what is configured + on the interface. + I think that needs to change.

The main goal +is to simplify `NMDevice`, so `NMDhcpClient` must become more complicated to +provide a simpler (but robust) API. + +NMDevice has basically two timeouts (talking about IPv4, but it applies +similarly to IPv6): `ipv4.dhcp-timeout` and `ipv4.required-timeout`. They +control how long NMDevice is willing to try, before failing the activation +altogether. Note that with `ipv4.may-fail=yes`, we may very well never want to +fail the activation entirely, regardless how DHCP is doing. In that case we +want to stay up, but also constantly retrying whether we cannot get a lease and +recover. + +Currently, if `NMDhcpClient` signals a failure, then it's basically up to +`NMDevice` to schedule and retry. That is complicated, and we should move the +complexity out of `NMDevice`. + +`NMDhcpClient` should have a simpler API: + +- `nm_dhcp_manager_start_ip[46]()`: creates (and starts) a `NMDhcpClient` + instance. The difference is, this function tries really hard not to fail + to create an `NMDhcpClient`. There is no explicit `start()`, but note that the + instance must not emit any signals before the next maincontext iteration. That is, + it only will call back the user after a timeout/idle or some other IO event, which + happens during a future iteration of the maincontext. + +- `nm_dhcp_client_stop()`: when `NMDevice` is done with the `NMDhcpClient` + instance, it will stop it and throw it away. This method exists because + `NMDhcpClient` is a `GObject` and ref-counted. Thus, we don't want to rely on + the last unref to stop the instance, but have an explicit stop. After stop, the + instance is defunct and won't emit any signals anymore. The class does not need + to support restarting a stopped instance. If `NMDevice` wants to restart DHCP, it + should create a new one. `NMDevice` would only want to do that, if the parameters + change, hence a new instance is in order (and no need for the complexity of + restart in `NMDhcpClient`). + +- as already now, `NMDhcpClient` is not very configurable. You provide most + (all) parameters during `nm_dhcp_manager_start_ip[46]()`, and then it keeps + running until stop. + +- `NMDhcpClient` exposes a simple state to the user: + + 1. "no lease, but good". When starting, there is no lease, but we are + optimistic to get one. This is the inital state, but we can also get back to + this state after we had a lease (which might expire). + + 1. "has a lease". Here there is no need to distinguish whether the current + lease was the first we received, or whether this was an update. In this state, + the instance has a lease and we are good. + + 1. "no lease, but bad". `NMDhcpClient` tries really hard, and "bad" does not + mean that it gave up. It will keep retrying, it's just that there is little + hope of getting a new lease. This happens, when you try to run DHCP on a Layer3 + link (WireGuard). There is little hope to succeed, but `NMDhcpClient` + (theoretically) will retry and may recover from this. Another example is when + we fail to start dhclient because it's not installed. In that case, we are not + optimistic to recover, however `NMDhcpDhclient` will retry (with backoff + timeout) and might still recover from this. For most cases, `NMDevice` will + treat the no-lease cases the same, but in case of "bad" it might give up + earlier. + +When a lease expires, that does not necessarily mean that we are now in a bad +state. It might mean that the DHCP server is temporarily down, but we might +recover from that easily. "bad" really means, something is wrong on our side +which prevents us from getting a lease. Also, imagine `dhclient` dies (we would +try to restart, but assume that fails too), but we still have a valid lease, +then possibly `NMDhcpClient` should still pretend all is good and we still have +a lease until it expires. It may be we can recover before that happens. The +point of all of this, is to hide errors as much as possibly and automatically +recover. `NMDevice` will decide to tear down, if we didn't get a lease after +`ipv4.dhcp-timeout`. That's the main criteria, and it might not even +distinguish between "no lease, but good" and "no lease, but bad". + +- `NMDhcpClient` will also take care of the `ipv4.dhcp-timeout` grace period. + That timeout is provided during start, and starts ticking whenever there is + no lease. When it expires, a timeout signal gets emitted. That's it. This is + independent from the 3 states above, and only saves `NMDevice` from scheduling + this timer themselves. + This is NM_DHCP_CLIENT_NOTIFY_TYPE_NO_LEASE_TIMEOUT notification. + +- for nettools, `nm_dhcp_client_can_accept()` indicates that when we receive a + lease, we need to accept/decline it first. In that case, `NMDevice` +optionally does ACD first, then configures the IP address first and calls +`nm_dhcp_client_accept()`. In case of ACD conflict, it will call +`nm_dhcp_client_decline()` (which optimally causes `NMDhcpClient` to get a +different lease). With this, the above state "has a lease" has actually three +flavors: "has a lease but not yet ACD probed" and "has a lease but +accepted/declined" (but `NM_DHCP_CLIENT_SIGNAL_STATE_CHANGED` gets only emitted +when we get the lease, not when we accept/decline it). With `dhclient`, when we +receive a lease, it means "has a lease but accepted" right away. + +- for IPv6 prefix delegation, there is also `needed_prefixes` and + `NM_DHCP_CLIENT_NOTIFY_TYPE_PREFIX_DELEGATED`. Currently `needed_prefixes` needs + to be specified during start (which simplifies things). Maybe `needed_prefixes` + should be changable at runtime. Otherwise, whether we have prefixes is similar + to whether we have a lease, and the simple 3 states apply. + +When NetworkManager quits, it may want to leave the interface up. In that case, +we still always want to stop the DHCP client, but possibly not deconfiguring +the interface. I don't think that this concerns `NMDhcpClient`, because `NMDhcpClient` +only provides the lease information and `NMDevice` is responsible to configure it. diff --git a/src/core/dhcp/nm-dhcp-client.c b/src/core/dhcp/nm-dhcp-client.c index f88c79c0be..6f71a44501 100644 --- a/src/core/dhcp/nm-dhcp-client.c +++ b/src/core/dhcp/nm-dhcp-client.c @@ -20,9 +20,13 @@ #include "NetworkManagerUtils.h" #include "nm-utils.h" +#include "nm-l3cfg.h" +#include "nm-l3-config-data.h" #include "nm-dhcp-utils.h" #include "nm-dhcp-options.h" #include "libnm-platform/nm-platform.h" +#include "nm-hostname-manager.h" +#include "libnm-systemd-shared/nm-sd-utils-shared.h" #include "nm-dhcp-client-logging.h" @@ -32,53 +36,19 @@ enum { SIGNAL_NOTIFY, LAST_SIGNAL };
