libhugetlbfs; ERROR: Line too long when parsing mounts
Last modified: 2024-07-12 16:31:34 UTC
The buffer used for parsing the mount list is not large enough. The buffer is artificially set at 2046, and will trigger this error when encountering a line that exceeds this. In container environments using overlay filesystems, the use of a large number of layers can easily result in valid entries which exceed this buffer size resulting in the error and the mount list not being processed completely.
Created attachment 870457 [details] proposed patch This is a simple patch to increase the buffer size to resolve the problem.
I proposed a more involved fix has been proposed upstream https://github.com/libhugetlbfs/libhugetlbfs/pull/77/commits/ The proposed patch attached here is a more conservative approach to resolving the issue.
