COMPONENT NAME

Resource Limits Manager for public_ip

CLOUDSTACK VERSION

CONFIGURATION

OS / ENVIRONMENT

SUMMARY

Due to certain race conditions between checking and incrementing of resource counts, the check can be bypassed. This leads to cases where account's allocated resources exceeds the accounts limit.

STEPS TO REPRODUCE

1. Create an account with public ip limit to 2
2. Create a network and deploy a VM (This will increase the public_ip count by 1 for the account).
3. Allocate different IPs to the same network in parallel (around 4-5 requests).

This sometimes leads to allocated resources exceeding the account's limit.

EXPECTED RESULTS

Count of allocated resources  should not exceed the account's limit.

ACTUAL RESULTS

Count of allocated resources exceeded the account's limit.
