News for "PR_CAPBSET_DROP 0 failed: Invalid argument"

Hi Tytung,
When I running logcat in HD2 with NexusHD2-JellyBean-CM10.2_V3.1 ROM, it shows following warn messages ceaseless:

W/dalvikvm(19710): PR_CAPBSET_DROP 34 failed: Invalid argument. Please make sure your kernel is compiled with file capabilities support enabled.

So I Google it, it's Zygoto warning log, causing prctl failed operation. Moreover Google has official upgrade this part code, reference https://android.googlesource.com/platform/dalvik/+/daa97a125fc2caa5faa44a31a768f318a26c7b65%5E!/#
It's not a big problem, but it seems to be always existent in NexusHD2 ROM, only if you modify some configuration when compiling the kernel.

Thank you for providing these info.
I don't like these warning messages either. It makes logcat hard to read.
The diff you provided was old (Feb 14 11:00:33 2013 -0800) and already in the CM git.
Anyway, I had uncommented ALOGW("PR_CAPBSET_DROP %d failed: %s ...) directly in my test version several days ago.
Paste your logcat to GitHub Gist or any similar websites, and link it in your post if you need any help. (Don't forget to tell us your HD2 setup/configuration.)

Device: HTC HD2 (LEO512)

OK, It's not a polite method but it's an effective method, attribute to naught log message. I'll try to know more about kernel's security module.
