Hi Craig,
Maybe it is something I am doing wrong. I am using build 994 and python still does not work correctly (seg faults)
When I built 994, it was a completely new build.
The uClibc.config file list the PIE setting as :
---------------------------
# uClibc security related options
#
UCLIBC_SECURITY=y
# UCLIBC_BUILD_PIE is not set
UCLIBC_HAS_SSP=y
# SSP_QUICK_CANARY is not set
# SSP_USE_ERANDOM is not set
# PROPOLICE_BLOCK_ABRT is not set
PROPOLICE_BLOCK_SEGV=y
# PROPOLICE_BLOCK_KILL is not set
UCLIBC_BUILD_SSP=y
UCLIBC_BUILD_RELRO=y
UCLIBC_BUILD_NOW=y
UCLIBC_BUILD_NOEXECSTACK=y
-----------------------------------------------------------------

Do you have any suggestions on where I am going wrong.

Thanks

Peter Beblo

Peter, is this related to the dynamic library loading bug, which was
very recently fixed (or seems to have been fixed in my testing) in
subversion r992

The bug seems in that case to be related to the PIE/SSP stack
protection stuff in uclibc, rather than the kernel itself.  Actually,
I think it would work if the DLLs and apps were all compiled with the
-fPIE flag to gcc (I think, but not sure about that).  But just
disabling PIE in uclibc is a lot easier.
