T8329: Fix interface naming for Azure VF interfaces with Accelerated Networking enabled - #5338
Conversation
📝 WalkthroughSummary by CodeRabbit
WalkthroughChangesAzure and Hyper-V VF interfaces now use Azure VF naming
Merge Risk: 🟠 High · up to The interface-naming changes can still assign configured names to the wrong interfaces, leave an interface down after a failed rename, miss late-appearing VF devices, or restore stale mappings. These are concrete correctness and availability risks for affected systems, so the PR is not ready to merge until they are fixed or explicitly accepted by the owner. 🚥 Pre-merge checks | ✅ 5✅ Passed checks (5 passed)

- Line 10: Update the VF naming flow involving the udev rule’s PROGRAM/NAME
actions and the vyos_vf_name helper so the reservation remains held until the
interface rename completes. Move the NAME rename into the helper or otherwise
defer lock release until after NAME="%c" succeeds, preventing concurrent VF
events from reusing the same vf_ethN name.
- Line 20: Update the Azure/Mellanox bypass rule near the VF naming PROGRAM so
it only jumps to vyos_net_end when vyos_vf_name %k succeeds and produces a valid
name. Ensure helper failures continue through the normal interface-naming
fallback instead of leaving the port as ethN.
In `@src/udev/vyos_vf_name`:
- Around line 33-62: The lock in the helper currently protects only name
selection and is released before the udev rename completes, so concurrent VF
events can select the same vf_ethN name. Update the reservation flow around
LOCK_ACQUIRED, cleanup, and the preferred-name logic to retain a per-name
reservation through the rename gap, and ensure the corresponding reservation is
released by the later cleanup/removal path after the rename completes.

🧰 Additional context used
🔍 Remote MCP
Relevant review context from systemd/u dev docs/tests:
NAME=renames in udev can fail on name collisions (-EEXIST/-EBUSY), and the rename path explicitly preserves rule-added properties across that failure path. That makes collision-avoidance in VF naming materially important.- A systemd test covers this exact case: when a
NAME=rename targets an already-taken interface name, the original interface remains and properties set before/during/after the failingNAME=are still present in the udev database.
I did not retrieve a direct doc snippet for %c substitution itself from the available Context7 sources.

@ritika0313 is it possible to assign names in a way that would match between (From the output shared in the first message:) Now:

|
Thanks @zdc for bringing this up. I actually had considered and tried to figure out if we could name the VF interfaces using the indices of their respective master interfaces’ name, since this would have been the cleanest collision-free naming. But unfortunately, I could not find a reliable way for achieving this index matching which would be a good design as well. This is due to the below reasons:
Because of this sequencing, an early udev-only rule cannot reliably assign VF names that always match final synthetic eth indices. Alternatively, if we could add a separate late stage renaming of VF interfaces after synthetic naming has fully stabilized (post-cloud-init), but it will add a second rename phase and more operational complexity/risk for limited functional gain. These are my findings and understanding. I would welcome any suggestions from anyone having experience in this domain, just in case I might have missed something being new to drivers and udev naming. |

@ritika0313 please check the following issue: Azure vm Standard_D8ds_v6, kernel 6.18.41-vyos, two Azure vNICs:
Hardware is MANA (1414:00ba, driver mana). Both MANA ports are renamed to vf_eth* during early boot, while the enP* names intended for MANA remain only as altnames It looks like the broad DRIVERS=="hv_pci" match also catches MANA. Should rule 63 explicitly skip mana or be limited to mlx*_core? |
|
Tested Standard_D8s_v3 with one non-AN WAN and three AN-enabled LAN NICs (the initial report deployment setup) Azure reports:
Cloud-init reports the same MAC/IP pairs:
Final VyOS state:
Configured values are:
Is this expected? Should applying the configured hw-id preserve the Azure vNIC’s MAC/IP/interface-role association? |
@alexk37 Upon checking I found that VyOS boots with net.ifnames=0 biosdevname=0 on the kernel command line. This disables udev's NamePolicy, and hence the enP* names appear just as altnames. Therefore, we would require to rename the mana interfaces as well similar to mlx interfaces. This would allow to vacate the eth* names to be utilized by the synthetic interfaces. Regarding MANA interface being exposed for the AN-disabled interfaces, this could possibly an issue on the Azure side since at first place, the VF interfaces should not appear and register themselves with the synthetic interface if AN is disabled. |

The issue is observed because for Azure, the VF interface and synthetic interface share the same mac address. We would need changes on top PR #5350 to skip the Azure VF interfaces from being considered as physical interfaces. @c-po I propose below changes: |

I tried disabling AN for all the NICs on the VM and still mana interfaces were being created. So I found the below information which states that VMs with sizes >=v5 will require accelerated Networking in any case (even if AN is disabled from control-plane configuration), which aligns with currently observed behavior on our VM. https://learn.microsoft.com/en-us/azure/virtual-network/create-virtual-machine-accelerated-networking?tabs=portal : |

@ritika0313 The PR description lists “missing udev add event, when change event is received directly” as a root cause. However, rule 63 matches only ACTION=="add", while rule 65 skips every non-add event. I reproduced this on the latest build using a real Azure mlx5_core VF: The trigger completed with status 0, but the VF remained named eth4. It retained the same MAC, PCI device and master eth2, confirming it was the same VF. Is the PR intended to handle the documented change-only case? If so, the current rules appear to skip it completely. |
We are handling the missed udev add event at the boot time, i.e the first change event received when no add event is received at all during boot time. Rule 65 has fallback handling for it. |
…Networking enabled ROOT-CAUSE: Some Azure VF interfaces miss to get renamed leading to errors in the downstream rules and mess up with the interface names. Two main problematic scenarios were found which prohibited the renaming of a VF interface to vf_ethN: 1. Missing udev add event, when change event is received directly 2. A VF interface registering during rootfs stage FIX: Rule 63: -Azure VF naming is now handled by a dedicated helper - vyos_vf_name to provide collision-free names for VF interfaces. The helper vyos_vf_name would be packaged into initramfs so the same behavior works in early boot and normal boot (a separate PR). -Rule 63 is now guarded to prevent recursive renaming of VF interfaces. Rule 65: -A fallback VF rename path has been added for any leftover VF interfaces that were missed to be renamed due to some unexpected situation. Those VF interfaces are renamed prior to running persistent renaming of synthetic interfaces. This prevents VF interfaces from being considered as synthetic interfaces which may lead to errors in the flow of execution. -Rule 65 is now guarded so generic persistent naming does not override VF names.
…cal interfaces during hw-id naming These interfaces include the Azure VF interfaces which share the same mac address with their master synthetic interface

eth0–eth3,eth5, andeth6. - This is directly relevant to validating the new allocator’s handling of gaps in interface indices.

Well tested by the QA team.
There was a problem hiding this comment.
As discussed this week with QA team and @ritika0313 , this is well-tested, and the need to exclude Azure VF interfaces bound under their synthetic parent from the revised vyos-net-name-resolve.py is addressed. As also discussed, a general approach to handle udev change events is out of scope for this PR.
Change summary
ROOT-CAUSE:
Some Azure VF interfaces miss to get renamed leading to errors in the downstream rules and mess up with the interface names. Two main problematic scenarios were found which prohibited the renaming of a VF interface to vf_ethN:
BEHAVIOR EXPLANATION (Pre-fix):
vf_ethNbecause the rule acts on add condition and not a change. So it remained exposed asethN. Once that happened, later handling depended on downstream rules.vf_ethN. After that, for rule 65vyos_net_namefails silently to execute as it is not available in initramfs. Hence,vf_ethNname becomes the final name. Though the final state is the intended state, the execution included a silent failure of the scriptvyos_net_name.NAME= vf_ethNfor VF interfaces , but rule 65 runs afterwards and overwrites NAME toethYvia vyos_net_name which becomes the (unintended) final name. To be noted,vyos_net_nameexecutes successfully now as it is available in rootfs.vf_based on just thedriverscondition in rule 63.FIX:
Rule 63:
-Azure VF naming is now handled by a dedicated helper -
vyos_vf_nameto provide collision-free names for VF interfaces. The helpervyos_vf_namewould be packaged into initramfs so the same behavior works in early boot and normal boot (a separate PR). -Rule 63 is now guarded to prevent recursive renaming of VF interfaces.Rule 65:
-A fallback VF rename path has been added for any leftover VF interfaces that were missed to be renamed due to some unexpected situation. Those VF interfaces are renamed prior to running persistent renaming of synthetic interfaces. This prevents VF interfaces from being considered as synthetic interfaces which may lead to errors in the flow of execution. -Rule 65 is now guarded so generic persistent naming does not override VF names.
