2017-02-09lib/utils.c: add mutex to get_psched_settings()Thomas Haller1-12/+20
Let's add a mutex to get_psched_settings() hoping to solve worst case scenarios when calling get_psched_settings() from multiple threads. Also, only read the environment variables once, who knows whether they are modified concurrently.

nl_us2ticks()/nl_ticks2us() (cherry picked from commit c33dec5a4a7df01730f90dd41f28a53c188aab46) Test: Compiles and ueventd proc_net denial is gone. Bug: 35197529 Change-Id: I09dbc1f36089c58f7965b26bf8a632a4865c3865
2017-02-09lib/utils.c: lazy initialize user_hz and psched_hzNick Kralevich1-1/+8
Rather than initializing user_hz and psched_hz when libnl is loaded, defer initialization of these variables to the first time they are used. This has several advantages: 1) Avoids an unnecessary permission denied error on /proc/net/psched, which can occur on systems where /proc/net isn't readable due to security policy. 2) Allows program code to initialize the environment variables PROC_NET_PSCHED and/or PROC_ROOT prior to the first libnl call, giving a program more flexibility about where libnl should look. 3) Trivially faster startup time (although unlikely to be significant). 4) Compiler may be able to prove that the get_psched_settings() function is unreachable and optimize appropriately, because the callers never (directly or indirectly) use this method. This could occur, for instance, in doing dead code elimination for programs which statically link libnl.
