            Target: x86_64
           Summary: OpenSSL RSA key generation hangs on x86_64
           Product: buildroot
           Version: unspecified
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Severity: normal
          Priority: P5
         Component: Other
        AssignedTo: unassigned at buildroot.uclibc.org
        ReportedBy: info at je-eigen-domein.nl
                CC: buildroot at uclibc.org
   Estimated Hours: 0.0


OpenSSL ends up in an endless 100% CPU loop when generating keys on x86_64.

E.g. when running "openssh" for the first time, or executing "openssl genrsa"


It seems that the openssl library buildroot produces includes code for 32-bit
systems, and does not work properly on x86_64.

In openssl.mk It tests for BR2_ARCH:

==
OPENSSL_TARGET_ARCH=generic32

[...]

ifeq ($(BR2_ARCH),x86_64)
OPENSSL_TARGET_ARCH=x86_64
endif
==

Not sure why, but this does not seem to work, and OpenSSL always builds as
"generic32"

If I use $(ARCH) instead, it does work properly and solves the key generation
problem:

==
ifeq ($(ARCH),x86_64)
OPENSSL_TARGET_ARCH=x86_64
endif
==

You're right.

There are two solutions to fix the issue. The first solution is to use $(ARCH),
as you suggested. ARCH is defined by project/Makefile.in. The second solution
if to change the test to be

ifeq ($(BR2_ARCH),"x86_64")

note the double quotes around x86_64.

Not sure which one is best, though.

It's because BR2_ARCH is a string value, so it contains " chars as well, E.G.
the tests have to be written as:

ifeq ($(BR2_ARCH),"x86_64")
OPENSSL_TARGET_ARCH=x86_64
endif

I'll fix it in git - Thanks.

Fixed in git (2a966bc) using ARCH
