H.J. Lu	17cef890c9	support: Replace _SC_MINSIGSTKSZ with _SC_SIGSTKSZ ... Replace _SC_MINSIGSTKSZ with _SC_SIGSTKSZ since sysconf (_SC_MINSIGSTKSZ) returns the minimum number of bytes of free stack space required in order to guarantee successful, non-nested handling of a single signal whose handler is an empty function while sysconf (_SC_SIGSTKSZ) returns the suggested minimum number of bytes of stack space required for a signal stack.

H.J. Lu	28d07380c2	support: Replace MINSIGSTKSZ with sysconf (_SC_MINSIGSTKSZ) ... Replace MINSIGSTKSZ with sysconf (_SC_MINSIGSTKSZ) since the constant MINSIGSTKSZ used in glibc build may be too small. Reviewed-by: Carlos O'Donell <carlos@redhat.com>	2021-07-09 15:20:55 -07:00
Adhemerval Zanella	ae8c243d24	support: Add support_stack_alloc ... The code to allocate a stack from xsigstack is refactored so it can be more generic. The new support_stack_alloc() also set PROT_EXEC if DEFAULT_STACK_PERMS has PF_X. This is required on some architectures (hppa for instance) and trying to access the rtld global from testsuite will require more intrusive refactoring in the ldsodefs.h header. Checked on x86_64-linux-gnu and i686-linux-gnu. I also ran tst-xsigstack on both hppa and ia64.	2021-07-08 13:48:06 -03:00
