## Description

In the Linux kernel, the following vulnerability has been resolved:  afs: Fix endless loop in directory parsing  If a directory has a block with only ".__afsXXXX" files in it (from uncompleted silly-rename), these .__afsXXXX files are skipped but without advancing the file position in the dir_context.  This leads to afs_dir_iterate() repeating the block again and again.  Fix this by making the code that skips the .__afsXXXX file also manually advance the file position.  The symptoms are a soft lookup:          watchdog: BUG: soft lockup - CPU#3 stuck for 52s! [check:5737]         ...
