external/sepolicy commit 99940d1af5
(https://android-review.googlesource.com/123331) removed /proc/net
access from domain.te.
Around the same time, system/core commit
9a20e67fa62c1e0e0080910deec4be82ebecc922
(https://android-review.googlesource.com/123531) was checked in.
This change added libnl as a dependency of libsysutils.
external/libnl/lib/utils.c has a function called get_psched_settings(),
which is annotated with __attribute__((constructor)). This code
gets executed when the library is loaded, regardless of whether or
not other libnl code is executed.
By adding the libnl dependency, even code which doesn't use the
network (such as vold and logd) ends up accessing /proc/net/psched.
For now, allow this behavior. However, in the future, it would be
better to break this dependency so the additional code isn't loaded
into processes which don't need it.
Addresses the following denials:
avc: denied { read } for pid=148 comm="logd" name="psched" dev="proc" ino=4026536508 scontext=u:r:logd:s0 tcontext=u:object_r:proc_net:s0 tclass=file permissive=0
avc: denied { read } for pid=152 comm="vold" name="psched" dev="proc" ino=4026536508 scontext=u:r:vold:s0 tcontext=u:object_r:proc_net:s0 tclass=file permissive=0

On 64 bit systems, all requests will first go to the 64 bit debuggerd
which will redirect to the 32 bit debuggerd if necessary. This avoids
any permissions problems where a java process needs to be able to
read the elf data for executables. Instead the permissions are granted
to debuggerd instead.
Also remove the permissions to read the /system/bin executables from
dumpstate since they aren't necessary any more.
