+Subject: [PATCH] binutils: Avoid renaming over existing files
+
+Renaming over existing files needs additional care to restore
+permissions and ownership, which may not always succeed.
+Additionally, other properties of the file such as extended attributes
+may be lost, making the operation flaky.
+
+For predictable results, resort to rename() only if the file does not
+exist, otherwise copy the file contents into the existing file.  This
+ensures that no additional tricks are needed to retain file
+properties.
+
+This also allows dropping of the redundant set_times on the tmpfile in
+objcopy/strip since now we no longer rename over existing files.
+
+binutils/
+
+	* ar.c (write_archive): Adjust call to SMART_RENAME.
+	* arsup.c (ar_save): Likewise.
+	* objcopy (strip_main): Don't set times on temporary file and
+	adjust call to SMART_RENAME.
+	(copy_main): Likewise.
+	* rename.c [!S_ISLNK]: Remove definitions.
+	(try_preserve_permissions): Remove function.
+	(smart_rename): Replace PRESERVE_DATES argument with
+	TARGET_STAT.  Use rename system call only if TO does not exist.
+	* bucomm.h (smart_rename): Adjust declaration.
+

+Subject: [PATCH] Reinstate various pieces backed out from smart_rename changes
+
+In the interests of a stable release various last minute smart_rename
+patches were backed out of the 2.36 branch.  The main reason to
+reinstate some of those backed out changes here is to make necessary
+followup fixes to commit 8e03235147a9 simple cherry-picks from
+mainline.  A secondary reason is that ar -M support isn't fixed for
+pr26945 without this patch.
+
+	PR 26945
+	* ar.c: Don't include libbfd.h.
+	(write_archive): Replace xmalloc+strcpy with xstrdup.
+	* arsup.c (temp_name, real_ofd): New static variables.
+	(ar_open): Use make_tempname and bfd_fdopenw.
+	(ar_save): Adjust to suit ar_open changes.
+	* objcopy.c: Don't include libbfd.h.
+	* rename.c: Rename and reorder variables.
+
