Hi,


In Android-M, below change in bionic was introduced

https://android-review.googlesource.com/122131

 

Which caused lot of SELinux denials to be logged regarding module_request 
(similar to below one) for 32bit systems, There is quite a lot of 
module_request denials when any 32bit executable is executed.

 

type=1400 audit(946685139.719:12): avc: denied { module_request } for 
pid=1970 comm="tzdatacheck" kmod="personality-8" 
scontext=u:r:tzdatacheck:s0 tcontext=u:r:kernel:s0 tclass=system 
permissive=1

 


The issue is discussed here

http://marc.info/?t=144190478400004&r=1&w=2



For kernel version < 4.0, is there any resolution available for resolving 
these denials with out having to backport the removal of execution domain 
patches from kernel 4.0?

Is adding a dontaudit for kernel module_request good option?


In our system disabling modules (CONFIG_MODULES=n) is currently not an 
option.


 

Regards,

Vishal
