2024-12-31elf: Do not change stack permission on dlopen/dlmopenAdhemerval Zanella7-93/+15
If some shared library loaded with dlopen/dlmopen requires an executable stack, either implicitly because of a missing GNU_STACK ELF header (where the ABI default flags implies in the executable bit) or explicitly because of the executable bit from GNU_STACK; the loader will try to set the both the main thread and all thread stacks (from the pthread cache) as executable. Besides the issue where any __nptl_change_stack_perm failure does not undo the previous executable transition (meaning that if the library fails to load, there can be thread stacks with executable stacks), this behavior was used on a CVE [1] as a vector for RCE. This patch changes that if a shared library requires an executable stack, and the current stack is not executable, dlopen fails. The change is done only for dynamically loaded modules, if the program or any dependency requires an executable stack, the loader will still change the main thread before program execution and any thread created with default stack configuration.

Move the x86-64 loader first, before the i386 and x32 loaders. In most cases, it's the loader the script needs. This avoids an error message if the i386 loader does not work. The effect of this change to the generated ldd script looks like this: -RTLDLIST="/lib/ld-linux.so.2 /lib64/ld-linux-x86-64.so.2 /libx32/ld-linux-x32.so.2" +RTLDLIST="/lib64/ld-linux-x86-64.so.2 /lib/ld-linux.so.2 /libx32/ld-linux-x32.so.2" Reviewed-by: Sam James <sam@gentoo.org>

2024-12-27nptl: Add <thread_pointer.h> for hppaMichael Jeanson1-0/+30
This will be required by the rseq extensible ABI implementation on all Linux architectures exposing the '__rseq_size' and '__rseq_offset' symbols to set the initial value of the 'cpu_id' field which can be used by applications to test if rseq is available and registered. As long as the symbols are exposed it is valid for an application to perform this test even if rseq is not yet implemented in libc for this architecture.

This was used to manage an IA-64 ABI divergence is no longere needed after the IA-64 removal. (It should be possible to encode all the required information in one machine word, so the pointer indirection is really unnecessary.
