From 0f2064107ba373ddcffb30afc55ac08b40c0585e Mon Sep 17 00:00:00 2001 From: Claudiu Zissulescu Date: Fri, 9 Nov 2018 13:14:00 +0200 Subject: [PATCH] [ARC] Fix local got entry list. Fix a memory leak appearing when the local got entry list was constructed. bfd/ xxxx-xx-xx Claudiu Zissulescu * arc-got.h (arc_get_local_got_ents): Revamp it; use elf_local_got_ents to store the local got list. (get_got_entry_list_for_symbo): Restructure it. * elf32-arc.c (elf_arc_relocate_section): Correct the call to get_got_entry_list_for_symbol. --- bfd/ChangeLog | 8 ++++++++ bfd/arc-got.h | 33 +++++++++++++++------------------ bfd/elf32-arc.c | 2 +- 3 files changed, 24 insertions(+), 19 deletions(-) diff --git a/bfd/ChangeLog b/bfd/ChangeLog index f0b36de223b..cce59683172 100644 --- a/bfd/ChangeLog +++ b/bfd/ChangeLog @@ -1,3 +1,11 @@ +2018-11-09 Claudiu Zissulescu + + * arc-got.h (arc_get_local_got_ents): Revamp it; use + elf_local_got_ents to store the local got list. + (get_got_entry_list_for_symbo): Restructure it. + * elf32-arc.c (elf_arc_relocate_section): Correct the call to + get_got_entry_list_for_symbol. + 2018-11-07 Nick Clifton * po/fr.po: Updated French translation. diff --git a/bfd/arc-got.h b/bfd/arc-got.h index 07722fdffd4..69e9aa32759 100644 --- a/bfd/arc-got.h +++ b/bfd/arc-got.h @@ -54,27 +54,26 @@ struct got_entry enum tls_got_entries existing_entries; }; +/* Return the local got list, if not defined, create an empty one. */ + static struct got_entry ** arc_get_local_got_ents (bfd * abfd) { - static struct got_entry **local_got_ents = NULL; - - if (local_got_ents == NULL) + if (elf_local_got_ents (abfd) == NULL) { - size_t size; - Elf_Internal_Shdr *symtab_hdr = &((elf_tdata (abfd))->symtab_hdr); - - size = symtab_hdr->sh_info * sizeof (bfd_vma); - local_got_ents = (struct got_entry **) - bfd_alloc (abfd, sizeof (struct got_entry *) * size); - if (local_got_ents == NULL) - return FALSE; - - memset (local_got_ents, 0, sizeof (struct got_entry *) * size); - elf_local_got_ents (abfd) = local_got_ents; + bfd_size_type amt = (elf_tdata (abfd)->symtab_hdr.sh_info + * sizeof (*elf_local_got_ents (abfd))); + elf_local_got_ents (abfd) = bfd_zmalloc (amt); + if (elf_local_got_ents (abfd) == NULL) + { + _bfd_error_handler (_("%pB: cannot allocate memory for local " + "GOT entries"), abfd); + bfd_set_error (bfd_error_bad_value); + return NULL; + } } - return local_got_ents; + return elf_local_got_ents (abfd); } static struct got_entry * @@ -167,9 +166,7 @@ get_got_entry_list_for_symbol (bfd *abfd, } else { - struct got_entry **local_got_ents - = arc_get_local_got_ents (abfd); - return &local_got_ents[r_symndx]; + return arc_get_local_got_ents (abfd) + r_symndx; } } diff --git a/bfd/elf32-arc.c b/bfd/elf32-arc.c index 30f47a5b220..668642c3024 100644 --- a/bfd/elf32-arc.c +++ b/bfd/elf32-arc.c @@ -1740,7 +1740,7 @@ elf_arc_relocate_section (bfd * output_bfd, reloc_data.should_relocate = TRUE; struct got_entry **list - = get_got_entry_list_for_symbol (output_bfd, r_symndx, h); + = get_got_entry_list_for_symbol (input_bfd, r_symndx, h); reloc_data.got_offset_value = relocate_fix_got_relocs_for_got_info (list, -- 2.30.2
