Shawn, I wonder if you can check this.

Comment 2

This should be SELinux related on L version.
Will ask member to check how to avoid this.

Comment 3

[Michael Vines [:m1] [:evilmachines]]

We've disabled SELinux over here, at least for now.  L enables SELinux enforcing mode and we'd need to write a bunch of new SELinux rules to make it happy with b2g.

libsigchain.so gets added to LD_PRELOAD from the init.rc files, we've removed that.

Hi Michael:
 It looks like we need to build /art/sigchainlib to make this error message away even we never use art in FxOS.

Do you have any suggestion?
Thanks!!
Shawn

Please see comment 4.  You'll have an init.rc file (it's /init.environ.rc in my build) that adds libsigchain.so to the LD_PRELOAD environment variable.  Just remove that and this error message should disappear.

Attachment: Disable the error message of libsigchain.so

Shawn, We don't have libsigchain.so in our system, so I think we need to do as m1 suggested. Could you review this patch? Thanks!
