Description Thomas Abraham 2023-10-25 18:20:52 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.

Comment 1 Thomas Abraham 2023-10-25 18:21:55 UTC

Created attachment 870457 [details]
proposed patch

This is a simple patch to increase the buffer size to resolve the problem.

Comment 2 Thomas Abraham 2023-10-25 18:23:21 UTC

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.
