It seems that some gcc versions might generates a stack frame for the
sigreturn stub requires on sparc signal handling. For instance:
$ cat test.c
#define _GNU_SOURCE
#include <sys/syscall.h>
__attribute__ ((__optimize__ ("-fno-stack-protector")))
void
__sigreturn_stub (void)
{
__asm__ ("mov %0, %%g1\n\t"
"ta 0x10\n\t"
: /* no outputs */
: "i" (SYS_rt_sigreturn));
}
$ gcc -v
[...]
gcc version 9.2.1 20200224 (Debian 9.2.1-30)
$ gcc -O2 -m64 test.c -S -o -
[...]
__sigreturn_stub:
save %sp, -176, %sp
#APP
! 9 "t.c" 1
mov 101, %g1
ta 0x10
! 0 "" 2
#NO_APP
.size __sigreturn_stub, .-__sigreturn_stub
As indicated by kernel developers [1], the sigreturn stub can not change
the register window or the stack pointer since the kernel has setup the
restore frame at a precise location relative to the stack pointer when
the stub is invoked.
I tried to play with some compiler flags and even with _Noreturn and
__builtin_unreachable after the asm does not help (and Sparc does not
support naked functions).
To avoid similar issues, as the stack-protector support also have
stumbled, this patch moves the implementation of the sigreturn stubs to
assembly.
Checked on sparcv9-linux-gnu and sparc64-linux-gnu with gcc 9.2.1
and gcc 7.5.0.

This patch moves the vDSO setup from libc to loader code, just after
the vDSO link_map setup. For static case the initialization
is moved to _dl_non_dynamic_init instead.
Instead of using the mangled pointer, the vDSO data is set as
attribute_relro (on _rtld_global_ro for shared or _dl_vdso_* for
static). It is read-only even with partial relro.
It fixes BZ#24967 now that the vDSO pointer is setup earlier than
malloc interposition is called.
Also, vDSO calls should not be a problem for static dlopen as
indicated by BZ#20802. The vDSO pointer would be zero-initialized
and the syscall will be issued instead.
Checked on x86_64-linux-gnu, i686-linux-gnu, aarch64-linux-gnu,
arm-linux-gnueabihf, powerpc64le-linux-gnu, powerpc64-linux-gnu,
powerpc-linux-gnu, s390x-linux-gnu, sparc64-linux-gnu, and
sparcv9-linux-gnu. I also run some tests on mips.

Fri Jan 17 19:07:07 1997 Andreas Schwab <schwab@issan.informatik.uni-dortmund.de>
* configure.in [$elf=yes]: Check for support of .previous and
.popsection in the assembler.

HAVE_ASM_POPSECTION_DIRECTIVE.
* libc-symbols.h (__make_section_unallocated) [HAVE_ELF]: Define
appropriate if either .previous or .popsection is supported.
(libc_warning) [HAVE_ELF]: Use it here.

* Makeconfig (CFLAGS-.so): Add -fno-common to prevent odd sorts of
errors that can occur when linking libc.so.
Mon Jan 20 05:20:49 1997 Ulrich Drepper <drepper@cygnus.com>
* elf/dl-load.c (open_path): When running setuid don't try
a directory if it is not given with the full name.
* elf/Makefile (before-compile): New variable. Mention trusted-dirs.h.
(trusted-dirs.h): Construct file from $(default-rpath) and
$(user-defined-trusted-dirs) variables.
* elf/dl-load.c (_dl_map_object): Pass additional argument to open_path
which is NULL except for the LD_LIBRARY_PATH pass in which case it
is a pointer to the list of directories from the trusted-dirs.h
file.
(open_path): Accept additional argument with list of trusted dirs.
When running setuid and a list of trusted dirs is given only use
those which are mentioned in the list.
* elf/rtld.c (dl_main): Don't reject whole LD_LIBRARY_PATH when
running setuid. Instead accept entries which do not contain a '/'.
* Makeconfig: Correct comment about +(default_cflags).

* elf/ldd.bash.in: Likewise.
* elf/rtld.c (dl_main): Do not always ignore LD_PRELOAD when the
binary runs setuid. It is save to use those entries which do not
contain a '/'. This is compatible with Solaris-2.
