Descripción
*** Pendiente de traducción *** In the Linux kernel, the following vulnerability has been resolved:<br />
<br />
gfs2: fiemap page fault fix<br />
<br />
In gfs2_fiemap(), we are calling iomap_fiemap() while holding the inode<br />
glock. This can lead to recursive glock taking if the fiemap buffer is<br />
memory mapped to the same inode and accessing it triggers a page fault.<br />
<br />
Fix by disabling page faults for iomap_fiemap() and faulting in the<br />
buffer by hand if necessary.<br />
<br />
Fixes xfstest generic/742.
