11 years agokernel/audit.c control character detection is off-by-one

kernel/audit.c control character detection is off-by-one

Hello,

According to my understanding there is an off-by-one bug in the
function:

   audit_string_contains_control()

in:

  kernel/audit.c

Patch is included.

I do not know from how many places the function is called from, but for
example, SELinux Access Vector Cache tries to log untrusted filenames via
call path:

avc_audit()
     audit_log_untrustedstring()
         audit_log_n_untrustedstring()
             audit_string_contains_control()

If audit_string_contains_control() detects control characters, then the
string is hex-encoded. But the hex=0x7f dec=127, DEL-character, is not
detected.

I guess this could have at least some minor security implications, since a
user can create a filename with 0x7f in it, causing logged filename to
possibly look different when someone reads it on the terminal.

hwmon: (lm75) cleanup/reorg

Minor cleanup and reorg of the lm75 code.

 - Kconfig provides a larger list of lm75-compatible chips

 - A top comment now says what the driver does (!) ... as in, just
   what sort of sensor is this??

 - Section comments now delineate the various sections of the driver:
   hwmon attributes, driver binding, register access, module glue.
   One driver binding function moved out of the attribute section,
   as did the driver struct itself.

 - Minor tweaks to legacy probe logic:  correct a comment, and
   remove a pointless variable.

 - Whitespace, linelength, and comment fixes.

This patch should include no functional changes.  It's preparation
for adding new-style (driver model) I2C driver binding.

When support for multiple TX queues were added, the

This causes heartburn for lockdep and it's not a healthy
thing to do with lots of TX queues anyways.
