Hi,

I've encountered a problem when enabling stack protection
(BR2_ENABLE_SSP) in combination with static binaries that uses threads.
The problem is that during start up the program gets a segfault in
__pthread_initialize_minimal_internal(), and I think this might be the
same issue as described in [1].

Investigation shows that the offending instruction is a:

  mov    %fs:0x28,%rax

where %fs is 0x00. The reason for that is that the pthread library is
compiled with stack protection but __pthread_initialize_minimal_internal
is called before __libc_setup_tls in static binaries.

I have created an ugly patch to verify my hypothesis. With that patch
the test program works, but what is the proper way to solve this issue?

Attached files (also at https://www.acc.umu.se/~guru/buildroot/)

add_broken_package.patch - add a test package to buildroot
pthread-broken-1.0.0.tar.gz - the test package
buildroot.config - buildroot config to use
static-pthread.patch - my proof-of-concept patch

Best regards,
Daniel Fahlgren

 This sounds like a uClibc issue. Could you verify by testing with uClibc 0.9.33
and/or musl and/or glibc? And then take it to the uClibc-ng mailing list:
http://mailman.uclibc-ng.org/cgi-bin/mailman/listinfo/devel/

Just to be sure, putting Waldemar in Cc.

 Wow, great bug information! But in the future, please use a defconfig instead
of a full config to reduce the list load.
