cdb4503 | Paul Chaignon | 19 August 2021, 12:12:44 UTC | routing: Fix incorrect detection of Linux slave devices [ upstream commit 07a443e9d262b4ed60ce7355740903ffe634f8d3 ] Using method Slave() exposed by the netlink package doesn't always work. In particular, it doesn't work on AKS, maybe because there's no master bond interface in that case. We should instead rely on the flags passed by Linux's netlink API.

Several interfaces can however have the same MAC address in the case of slave devices. In such a case, the wrong interface may be selected. To avoid this, we skip Linux slave devices during the lookup by MAC address. Thus, in case of slave devices, we will select the master device.

633db21 | Aditi Ghag | 24 June 2021, 05:19:35 UTC | cilium-daemonset: Host cgroup root mount as alternative to auto-mount [ upstream commit 826531447fa5ba18d2fe0df8d7eed9881b47235d ] Cilium agent daemonset auto mounts cgroup2 filesystem on the host by default. However, it needs to mount host's `/proc` inside an init container in order to do that. To disable this auto-mount behavior, we introduce a helm option. When auto-mount is disabled, users can specify the mount point on the underlying host where cgroup v2 fs is already mounted. We then volume mount this directory inside the cilium agent pod. The reason why we don't set the host cgroup2 mount point to a hard-coded path such as `/sys/fs/cgroup`, is because cgroup2 filesystem mount point can be platform dependent. See this note in the cgroup manpage [1] - >Note that on many modern systems, systemd(1) automatically mounts the cgroup2 filesystem at /sys/fs/cgroup/unified during the boot process.

00d4873 | Aditi Ghag | 21 May 2021, 05:10:57 UTC | cilium-daemonset: Fix ineffective socket-lb caused by incorrect cgroup2 fs mount [ upstream commit fa8bea45562f7ea3005708e968c419720a0ad190 ] If container runtimes are run with cgroup v2, Cilium agent pod would be deployed in a separate cgroup namespace. For example, Docker container runtime with cgroupv2 support switched to private cgroup namespace mode as the default [1]. Due to cgroup namespaces [2], the cgroup fs mounted by the Cilium pod points to a virtualized cgroup hierarchy instead of the host cgroup root. As a result, BPF programs are attached to the nested cgroup root, and socket-lb isn't effective for other pods. Fix: Mount cgroup2 fs from the host so that BPF programs are attached at the host cgroup root. A new init container is added to the Cilium Daemonset that mounts cgroup2 fs on the host. The `/proc/1/ns/` directory on the host is required to be mounted so that cgroup and mount namespaces are enabled as enterable namespaces while running the `nsenter` command. Additionally, cgroup2 fs can be attached to different paths so let's mount it on the host at a cilium-specific custom location. Cilium can thus have control over the location (e.g., create the directory if it doesn't exist). This also helps in effectively identifying if a cgroup2 mount already exists at the custom location.

1973b1d | Gilberto Bertin | 18 June 2021, 10:22:59 UTC | bpf: fix iptables masquerading for node -> remote pod traffic [ upstream commit 31927a2e8db5c7ced889cc3618d2372ba4e999c9 ] When Cilium runs with KPR, host-firewall or bandwidth manager, it will try to auto-derive one or more devices to which the bpf_host program is attached. This program will, among other things, redirect ingress traffic destined to a pod to the pod's lxc device using `bpf_redirect()`. This causes the traffic to bypass the nf_conntrack table, leading to a situation where traffic leaving the pod after the connection's been established will be (incorrectly) masqueraded in case Iptables masquerading is enabled, since the connection is not tracked by netfilter. This commit fixes this by skipping `bpf_redirect()` when we detect this case (i.e. traffic is flowing through bpf_host attached to a physical device and Cilium has installed Iptables rules which require conntrack).

4a6016e | Daniel Borkmann | 02 March 2021, 12:23:51 UTC | bpf: do not blindly push to stack for bpf host routing on encap [ upstream commit 8b0a9a82a77e433b6ec8200df655cf627a3fb317 ] Also in case of vxlan/geneve, let the bpf_host perform local delivery into Pods, for example, for the case of K8s services where traffic arrives on the phys dev and does not go via vxlan/geneve dev. For this scenario, the same optimizations can be performed as with the direct routing case. Hence lift the skip_redirect constraints for encaps given the return path in bpf_lxc will also support this. Typical case for this is cloud LB pushing inbound traffic to a node's NodePort service as one example where this will improve performance. For the bpf_host prog attached to the phy dev, this means that we perform the ipv4_local_delivery() into a local Pod backend for a service more efficiently compared to before where it gets pushed up the stack, then routed into cilium_host and pushed from there. Note that in tunnel mode the Pod's host-facing lxc devices do not have a policy tc egress program attached, so the tail call into the v{4,6} policy prog of the bpf_lxc is now done at an earlier point which also becomes visible in the RR numbers. Only if there's no local endpoint for the target address, we push up the stack via CTX_ACT_OK as before.

6cba74c | Chris Tarazi | 28 June 2021, 17:07:45 UTC | daemon, node: Fix faulty router IP restoration logic [ upstream commit ff63b0775c0d7603822d79c36c32d274e1ea6a53 ] [ Backporter's notes: Removed AlibabaCloud IPAM as it's not available in the v1.9 tree. ] When running in ENI or Alibaba IPAM mode, or any CRD-backed IPAM mode ("crd") and upon Cilium restart, it was very likely that `cilium_host` was assigned an additional IP. Below is a case where Cilium was restarted 3 times, hence getting 3 additional router IPs: ``` 4: cilium_host@cilium_net: <BROADCAST,MULTICAST,NOARP,UP,LOWER_UP> mtu 9001 qdisc noqueue state UP group default qlen 1000 link/ether 66:03:3c:07:8c:47 brd ff:ff:ff:ff:ff:ff inet 192.168.35.9/32 scope link cilium_host valid_lft forever preferred_lft forever inet 192.168.34.37/32 scope link cilium_host valid_lft forever preferred_lft forever inet 192.168.57.107/32 scope link cilium_host valid_lft forever preferred_lft forever inet6 fe80::6403:3cff:fe07:8c47/64 scope link valid_lft forever preferred_lft forever ``` This was because in CRD-backed IPAM modes, we wait until we fully sync with K8s in order to derive the VPC CIDR, which becomes the pod CIDR on the node. Since the router IP restoration logic was using a different pod CIDR during the router IP validation check, it was erroneously discarding it. This was observed with: ``` 2021-06-25T13:59:47.816069937Z level=info msg="The router IP (192.168.135.3) considered for restoration does not belong in the Pod CIDR of the node. Discarding old router IP." cidr=10.8.0.0/16 subsys=node ``` This is problematic because the extraneous router IPs could be also assigned to pods, which would break pod connectivity. The fix is to break up the router IP restoration process into 2 parts. The first is to attempt a restoration of the IP from the filesystem (`node_config.h`). We also fetch the router IPs from Kubernetes resources since they were already retrieved prior inside k8s.WaitForNodeInformation(). Then after the CRD-backed IPAM is initialized and started (*Daemon).startIPAM() is called, we attempt the second part. This includes evaluating which IPs (either from filesystem or from K8s) should be set as the router IPs. The IPs from the filesystem take precedence. In case the node was rebooted, the filesystem will be wiped so then we'd rely on the IPs from the K8s resources. At this point in the daemon initialization, we have the correct CIDR range as the pod CIDR range to validate the chosen IP.

fb819aa | Chris Tarazi | 25 May 2021, 19:38:10 UTC | k8s, node: Restore router IPs (`cilium_host`) from K8s resource [ upstream commit beb8bdea384fdc4ccb10769142c8981bb10334d5 ] [ Backporter's notes: * Resolved simple conflict with RegisterCRDs() inside pkg/k8s/init.go. Resolution was to keep both the newly added function and RegisterCRDs(). * Due to https://github.com/cilium/cilium/pull/14800 not being backported to the v1.9 tree, we don't have the ability to set the router IPs via args, hence I needed to modify the warning msg in the case of mismatched router IPs between the filesystem and k8s resources. The user will not be advised to set the router IPs as a workaround, like they would in the v1.10 version of this. ] Previously, after a node reboot, Cilium would allocate a new router IP and append it slice of node IPs. Since the node IPs have already been synced to the K8s resource, meaning there are already IPs present (from the previous Cilium instance), the router IP is appended to the slice. In other parts of Cilium, it is assumed that the router IP is the first node IP (first element of the slice). Since the new router IP has been appended to the end, it is no longer where it is expected, aka no longer the first element. This causes a mismatch of which router IP is to be used. There should only ever be one router IP (one IPv4 or one IPv6). In case of a node reboot, the router IPs cannot be restored because they are wiped away due to the Cilium state dir being mounted as a tmpfs [1]. This commit fixes this to restore the router IPs from the K8s resource (Node or CiliumNode) if they are present in the annotations. This prevents the possibility of having more than one router IP, as described above. Note that router IPs from the K8s resource are only restored if no router IP was found on the filesystem, which is considered the source of truth. In other words, the filesystem takes precedence over the K8s resource. The user is warned in cases of a mismatch between the two different sources. We also check that the IP to be restored is within the pod / node CIDR range, otherwise we ignore it from restoration. [1]: Linux distributions mount /run as tmpfs and Cilium's default state directory is created under /run. (It's worth mentioning that it's also common for /var/run to be symlinked to /run.)

f188ac7 | Paul Chaignon | 16 June 2021, 22:13:33 UTC | contrib: Identify upstream commits by author and date [ upstream commit 4ddb158e2189fd4298d8adb92200b6937122cb5f ] When listing the commits of pull requests to backport, GitHub doesn't offer a way to find the corresponding commits merged in master. We therefore have to do it manually. To that end, we first retrieve a candidate commit by matching on the exact commit title. Several commits can have the same title however, so we need another check to confirm the candidate commit is the same commit as the pull request's. We currently use 'git patch-id' for the second check. That command computes a unique ID for a patch. It can however have false negatives. For example, 9515d1e ("docs: add a reference of helm values") and de62fa3 ("docs: add a reference of helm values") refer to the same patch, the first being from the pull request and the second from master (i.e., once merged). Nevertheless, when we run 'git patch-id', we get two different IDs: $ git show 9515d1e | git patch-id 5d928411d72fcdb5c9c24ab2138896e6709e578c 9515d1ea37f1d1122ece73cf061cf47590e90f9e $ git show de62fa3 | git patch-id de14f63774d0f56ecc1e22db615987bedffe1e4b de62fa37c9ac679fd45bb617e8759dd7a4918ccb Comparing the two commits shows that the difference is actually due to changes not introduced by this commit: $ diff <(git show 9515d1e) <(git show de62fa3) [...] 1997,1998c1997,1998 < @@ -118,7 +118,7 @@ contributors across the globe, there is almost always someone available to help. < | debug.enabled | bool | `false` | Enable debug logging | --- > @@ -119,7 +119,7 @@ contributors across the globe, there is almost always someone available to help. > | disableEndpointCRD | string | `"false"` | Disable the usage of CiliumEndpoint CRD | [...] We however don't need to use 'git patch-id'. Using the author's email address and date (+ commit title) is usually enough to uniquely identify commits on master. If someone sends two commits with the same title and author date (to the second), then they are definitely trying to game the system. In that unlikely event, we have two rounds of reviews (original pull request and backport pull request) to catch it. This commit implements that change. "%ae%at" (author email followed by author date without spaces) is used as the commit ID instead of the ID generated by git patch-id.

It has been observed with mlx5, for example. The hw csum failure was only reproducible under the following conditions: - Protocol is ICMP, e.g. triggered by Cilium health probe packets - Pod from one node was pinging a remote node address - BPF based masquerading was used to SNAT Pod IP to node IP - BPF NAT engine found a collision in the NAT table such that it was forced to select a different ICMP id, and hence caused L4 rewrites In the case of ICMPv4 the bug was that BPF_F_PSEUDO_HDR was used for updating the L4 checksum. However, ICMPv4 does not have a pseudo header, only ICMPv6. The packet based csum was okay either way, but the flag caused to have a buggy skb->csum. Setting flag to 0 for ICMPv4 stopped the hw csum traces.

For example, systemd-networkd can remove the ENI IP assigned by Cilium if the carrier is temporarily down, thus breaking SNAT. We previously had a similar section regarding NetworkManager and DHCP in the EKS installation guide, but the EKS guide has since been replaced by the Cilium CLI installation guide. This section here therefore acts as a replacement and states that the devices need to be unmanaged (e.g. disabling DHCP is not enough for systemd-networkd).

If a command ends with a trailing backslash, copy the next line as well. For example, the following snippet: .. code-block:: shell-session $ ls -l foo cat $ echo 1 \ 2 \ 3\ 4 $nospace # exit should place the following text into the clipboard: ls -l echo 1 2 3 4 exit The button is added for the following blocks, when they contain several lines and at least one command is found in the block: - "code-block", but with language "shell-session" only, - Literal blocks ("::"), - Parsed literals.

Having a K8sVerifier-specific image also allows us to include a patch for the tc binary, to increase the maximum size of the verifier log buffer. In the K8sVerifier test, we load all BPF programs in verbose mode, so the log buffer is always needed (vs. only in case of retry following a load error usually). A small log buffer can lead to a load failure that is actually a false positive (it's just the log buffer being too small and not an actual issue with the BPF program).

This change fixes the complexity issue we're hitting on v5.10+ when socket-level load balancing is disabled (via enable-host-services=false or kube-proxy-replacement=disabled). Using the third eBPF instruction set doesn't reduce complexity for all BPF programs but it leads to more standard numbers, with less variations in complexities. A big part of this improvement is due to the implicit use of mattr=+alu32 to enable 32-bit eBPF registers. In addition to the end-to-end test on bpf-next, this change was tested on kernels 5.10 and 5.11 with the existing verifier-test.sh, compiling the datapath with both KERNEL=netnext and KERNEL=419.

4d36cac | Paul Chaignon | 21 April 2021, 15:15:14 UTC | bpf: Fixes to support mattr=+alu32 [ upstream commit ad0d3cf341402feaf34cb612c0f57732b0f5d5b4 ] mattr=+alu32, supported since LLVM 7.0 and implied by mcpu=v3, enables the use of 32-bit registers in BPF bytecode. Enabling this compiler option can however result in loading issues as illustrated below. 12: (61) r1 = *(u32 *)(r0 +80) // ctx->data_end 13: (61) r6 = *(u32 *)(r0 +76) // ctx->data 14: (bc) w7 = w6 // <- verifier looses track of inferred pkt type here. [...] 38: (71) r1 = *(u8 *)(r7 +20) R7 invalid mem access 'inv' These errors typically happen because the data and data_end pointers are actually 32-bit registers. Depending on how these pointers are used, LLVM sometimes makes use of that assumption (e.g., 32-bit assignment on instruction 14 above). The verifier is however not able to follow and reject such programs. We can usually work around those by ensuring these pointers are only used via 64-bit types. This commit implements this wherever needed to pass the verifier. Signed-off-by: John Fastabend <john.fastabend@gmail.com> Signed-off-by: Paul Chaignon <paul@cilium.io> | 23 June 2021, 10:15:52 UTC |
e665022 | Jarno Rajahalme | 12 January 2021, 19:46:47 UTC | datapath: Do not use proxy original source address with tunneling [ upstream commit 4b769cb53a15a7dcc30b8d2eac36094cb4cc071e ] Tunnel headers carry the source security ID so the use of original source address on Envoy upstream connections is not needed when tunneling. This commit disables the use of original source address when tunneling is used, which allows Envoy redirection to work also when using Kind to simulate multiple nodes in a single docker host.

1fd0920 | Alexandre Perrin | 07 June 2021, 15:52:24 UTC | examples: add an example of a hubble-cli Deployment In order to debug Relay to Hubble connectivity issues, it is sometimes useful to have a Pod running with the Hubble CLI. Because the Relay image is based on a scratch image, kubectl exec'ing into it is not possible. While the Hubble CLI can be found in the Cilium Pods, the Relay certificate needed to establish the mTLS handshake to the Hubble server is not mounted into the Cilium Pods. This commit introduce a new hubble-cli Deployment example. When debugging Relay mTLS issues, it can be used to quickly run a hubble-cli Pod: kubectl apply -n kube-system -f path/to/hubble-cli.yaml Since the Relay mTLS certificates are mounted into the hubble-cli Pods, one can connect to a Hubble server given it's IP address and ServerName: kubectl exec -it -n kube-system deployment/hubble-cli -- \ hubble observe --server tls://${IP?}:4244 \ --tls-server-name ${SERVERNAME?} \ --tls-ca-cert-files /var/lib/hubble-relay/tls/hubble-server-ca.crt \ --tls-client-cert-file /var/lib/hubble-relay/tls/client.crt \ --tls-client-key-file /var/lib/hubble-relay/tls/client.key Both ${IP} and ${SERVERNAME} can be obtained by either looking at the Hubble Relay Pod logs or alternatively by running: kubectl exec -it -n kube-system deployment/hubble-cli -- \ hubble watch peers --server unix:///var/run/cilium/hubble.sock Signed-off-by: Alexandre Perrin <alex@kaworu.ch> | 17 June 2021, 12:10:15 UTC |
