Sounds good. Denke, when you refresh patch please include this patch along

Re: [OE-core] [PATCH 1/1] expat: upgrade to 2.2.2

[Burton, Ross]

I've filed a bug upstream about the failure on Debian 8:
https://github.com/libexpat/libexpat/issues/97

Defining XML_POOR_ENTROPY will allow expat to fall back to weak entropy on
hosts that don't have direct support for getrandom().

Re: [OE-core] [PATCH 1/1] expat: upgrade to 2.2.2

[Burton, Ross]

I didn't see that upgrade, but yes it will.

expat 2.2.2 demands either getrandom() from glibc (2.25 onwards) or
SYS_getrandom (not sure what glibc added this, but its not in Debian 8's
2.19.

I posted another patch doing this upgrade. I wonder if it has same

It's failing on Debian 8, which is kernel 4.9.0:

| ../expat-2.2.2/lib/xmlparse.c:56:3: error: #error You do not have support
for any sources of high quality entropy enabled. For end user security,

Re: [OE-core] [PATCH 1/1] expat: upgrade to 2.2.2

[Dengke Du]

Hi Ross

Do we need to add a patch to glibc to support the ubuntu 14.04 (or 
kernel version older than 3.17)?
