[$] A setback for fs-verity

Post Syndicated from corbet original https://lwn.net/Articles/775872/rss

The fs-verity mechanism, created to protect
files on Android devices from hostile modification by attackers, seemed to
be on track for inclusion into the mainline kernel during the current merge
window when the
patch set
was posted at the beginning of November. Indeed, it wasn’t
until mid-December that some other developers started to raise objections.
The resulting conversation has revealed a deep difference of opinion regarding
what makes a good filesystem-related API and may have implications for how
similar features are implemented in the future.
