From 6b02746a0e29b1007efd4feb137e2da3e681fc68 Mon Sep 17 00:00:00 2001 From: Gleb Fotengauer-Malinovskiy Date: Tue, 28 Sep 2021 20:11:26 +0930 Subject: [PATCH] PR28391, strip/objcopy --preserve-dates *.a: cannot set time After commit 985e0264516 copy_archive function began to pass invalid values to the utimensat(2) function when it tries to preserve timestamps in ar archives. This happens because the bfd_stat_arch_elt implementation for ar archives fills only the st_mtim.tv_sec part of the st_mtim timespec structure, but leaves the st_mtim.tv_nsec part and the whole st_atim timespec untouched leaving them uninitialized PR 28391 * ar.c (extract_file): Clear buf for preserve_dates. * objcopy.c (copy_archive): Likewise.
