description |
The stress-ng numa stress fails because of a miscalculation of the maximum number of NUMA nodes.
Previously we were getting an upper bound to the number of max nodes instead of the actual number.
That made migrate_pages() fail in some devices due to having bits in the masks set beyond the maximum node identifier. We use now the count of bits in "Mems_allowed" to calculate the maximum number of NUMA nodes.
Fix is https://kernel.ubuntu.com/git/cking/stress-ng.git/commit/?id=2d4859745fd35f82081ddf8087350f85f2964971 |
SRU Cosmic, Bionic
[Justification]
The stress-ng numa stress fails because of a miscalculation of the maximum number of NUMA nodes.
Previously we were getting an upper bound to the number of max nodes instead of the actual number.
That made migrate_pages() fail in some devices due to having bits in the masks set beyond the maximum node identifier.
[Fix]
he fix is to the count of bits in "Mems_allowed" to calculate the maximum number of NUMA nodes. Upstream fix already in -proposed for Disco.
Fix is https://kernel.ubuntu.com/git/cking/stress-ng.git/commit/?id=2d4859745fd35f82081ddf8087350f85f2964971
This won't be fixed for Xenial as it has a much older mechanism for checking NUMA nodes and backporting all the changes to apply this fix is too risky for a SRU.
[Regression Potential]
This could break the NUMA stress-ng stressor node checking if this fix is incorrect; however it currently is broken so the change won't make the situation any worse than it is now. |
