Linus Torvalds 299f89d53e Leaking-addresses patches for 4.17-rc1
Here is the patch set for the 4.17-rc1 merge window.  This set
 represents improvements to the scripts/leaking_addresses.pl script.  The
 major improvement is that with this set applied the script actually runs
 in a reasonable amount of time (less than a minute on a standard stock
 Ubuntu user desktop).  Also, we have a second maintainer now and a tree
 hosted on kernel.org
 
 We do a few code clean ups.  We fix the command help output.  Handling
 of the vsyscall address range is fixed to check the whole range instead
 of just the start/end addresses.  We add support for 5 page table levels
 (suggested on LKML).  We use a system command to get the machine
 architecture instead of using Perl.  Calling this command for every
 regex comparison is what previously choked the script, caching the
 result of this call gave the major speed improvement.  We add support
 for scanning 32-bit kernels using the user/kernel memory split.  Path
 skipping code refactored and simplified (meaning easier script
 configuration).  We remove version numbering.  We add a variable name to
 improve readability of a regex and finally we check filenames for
 leaking addresses.
 
 Currently script scans /proc/PID for all PID.  With this set applied we
 only scan for PID==1. It was observed that on an idle system files under
 /proc/PID are predominantly the same for all processes.  Also it was
 noted that the script does not scan _all_ the kernel since it only scans
 active processes.  Scanning only for PID==1 makes explicit the inherent
 flaw in the script that the scan is only partial and also speeds things up.
