- Summary
- gfs2: fiemap page fault fix
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
gfs2: fiemap page fault fix
In gfs2fiemap(), we are calling iomapfiemap() while holding the inode glock. This can lead to recursive glock taking if the fiemap buffer is memory mapped to the same inode and accessing it triggers a page fault.
Fix by disabling page faults for iomap_fiemap() and faulting in the buffer by hand if necessary.
Fixes xfstest generic/742.
