+Subject: [PATCH] x86: Add a GNU_PROPERTY_X86_ISA_1_USED note if needed
+
+When -z separate-code, which is enabled by default for Linux/x86, is
+used to create executable, ld won't place any data in the code-only
+PT_LOAD segment. If there are no data sections placed before the
+code-only PT_LOAD segment, the program headers won't be mapped into
+any PT_LOAD segment. When the executable tries to access it (based
+on the program header address passed in AT_PHDR), it will lead to
+segfault. This patch inserts a GNU_PROPERTY_X86_ISA_1_USED note if
+there may be no data sections before the text section so that the
+first PT_LOAD segment won't be code-only and will contain the program
+header.
+
+Testcases are adjusted to either pass "-z noseparate-code" to ld or
+discard the .note.gnu.property section. A Linux/x86 run-time test is
+added.
+

+
+ PR ld/23428
+ * elfxx-x86.c (_bfd_x86_elf_link_setup_gnu_properties): If the
+ separate code program header is needed, make sure that the first
+ read-only PT_LOAD segment has no code by adding a
+ GNU_PROPERTY_X86_ISA_1_USED note.

+Subject: [PATCH] Close resource leaks in the BFD library's plugin handler.
+
+ PR 23460
+ * plugin.c (bfd_plugin_open_input): Close file descriptor if the
+ call to fstat fails.
+ (try_claim): Always close the file descriptor at the end of the
+ function.
+ (try_load_plugin): If a plugin has already been registered, then
+ skip the dlopen and onload steps and go straight to claiming the
+ file. If these is an error, close the plugin.
