+Subject: [PATCH] x86: Disallow TLS relocation in non executable section
+
+Since TLS relocations are applied to executable machine instructions,
+disallow TLS relocation in non-SHT_PROGBITS, non-SHF_EXECINSTR section.
+
+        PR ld/33451
+        PR ld/33502
+        * elf32-i386.c (elf_i386_tls_transition): Disallow TLS relocation
+        in non-SHT_PROGBITS, non-SHF_EXECINSTR section.
+        (elf_i386_scan_relocs): Likewise.
+        * elf64-x86-64.c (elf_x86_64_tls_transition): Likewise.
+        (elf_x86_64_scan_relocs): Likewise.
+        * elfxx-x86.c (_bfd_x86_elf_link_report_tls_invalid_section_error):
+        New.
+        * elfxx-x86.h (_bfd_x86_elf_link_report_tls_invalid_section_error):
+        Likewise.
