Bug ID: 197390
Summary: Add assertion to check whether shm files have maximum
FileProtection of CompleteUnlessOpen
Product: WebKit
Version: WebKit Nightly Build
Hardware: Unspecified
OS: Unspecified
Status: NEW
Severity: Normal
Priority: P2
Component: New Bugs
Assignee: webkit-unassigned at lists.webkit.org
Reporter: sihui_liu at apple.com
We have seen crashes where process gets killed because it tries accessing shm file after device is locked. We are suspecting this is because database protection class of shm file is set to be Complete by apps after it's created with lower protection level.
