2014-07-16Properly match PLT entry against .got.plt relocationH.J. Lu1-9/+80
Relocations against .got.plt section may not be in the same order as entries in PLT section. It is incorrect to assume that the Ith reloction index against .got.plt section always maps to the (I + 1)th entry in PLT section. This patch matches the .got.plt relocation offset/index in PLT entry against the index in .got.plt relocation table. It only checks R_*_JUMP_SLOT and R_*_IRELATIVE relocations. It ignores R_*_TLS_DESC and R_*_TLSDESC relocations since they have different PLT entries. bfd/ PR binutils/17154 * elf32-i386.c (elf_i386_plt_sym_val): Only match R_*_JUMP_SLOT and R_*_IRELATIVE relocation offset with PLT entry. * elf64-x86-64.c (elf_x86_64_plt_sym_val): Likewise.

2014-06-13Don't call bfd_link_hash_table_freeAlan Modra1-4/+1
Freeing the linker hash table is a royal pain. It can't be freed before the _bfd_write_contents call in bfd_close, because some target bfd_write_contents functions access the hash table. It can't be freed after bfd_close either, since bfd_alloc memory holding side data structures disappears (PR17047). Clearly the only place it can be freed is actually in bfd_close. This patch doesn't do that, but kills off the existing means of freeing the hash table via a bfd target xvec call. bfd/ PR 17047 * targets.c (BFD_JUMP_TABLE): Delete NAME##_bfd_link_hash_table_free.

2014-02-19Create the second PLT for BND relocationsH.J. Lu1-37/+416
Intel MPX introduces 4 bound registers, which will be used for parameter passing in x86-64. Bound registers are cleared by branch instructions. Branch instructions with BND prefix will keep bound register contents. This leads to 2 requirements to 64-bit MPX run-time: 1. Dynamic linker (ld.so) should save and restore bound registers during symbol lookup. 2. Change the current 16-byte PLT0: ff 35 08 00 00 00 pushq GOT+8(%rip) ff 25 00 10 00 jmpq *GOT+16(%rip) 0f 1f 40 00 nopl 0x0(%rax) and 16-byte PLT1: ff 25 00 00 00 00 jmpq *name@GOTPCREL(%rip) 68 00 00 00 00 pushq $index e9 00 00 00 00 jmpq PLT0 which clear bound registers, to preserve bound registers. We use 2 new relocations: to mark branch instructions with BND prefix. When linker sees any R_X86_64_PC32_BND or R_X86_64_PLT32_BND relocations, it switches to a different PLT0: ff 35 08 00 00 00 pushq GOT+8(%rip) f2 ff 25 00 10 00 bnd jmpq *GOT+16(%rip) 0f 1f 00 nopl (%rax) to preserve bound registers for symbol lookup and it also creates an external PLT section, .pl.bnd. Linker will create a BND PLT1 entry in .plt: 68 00 00 00 00 pushq $index f2 e9 00 00 00 00 bnd jmpq PLT0 0f 1f 44 00 00 nopl 0(%rax,%rax,1) and a 8-byte BND PLT entry in .plt.bnd: f2 ff 25 00 00 00 00 bnd jmpq *name@GOTPCREL(%rip) 90 nop Otherwise, linker will create a legacy PLT1 entry in .plt: 68 00 00 00 00 pushq $index e9 00 00 00 00 jmpq PLT0 66 0f 1f 44 00 00 nopw 0(%rax,%rax,1) and a 8-byte legacy PLT in .plt.bnd: ff 25 00 00 00 00 jmpq *name@GOTPCREL(%rip) 66 90 xchg %ax,%ax The initial value of the GOT entry for "name" will be set to the the "pushq" instruction in the corresponding entry in .plt. Linker will resolve reference of symbol "name" to the entry in the second PLT, .plt.bnd. Prelink stores the offset of pushq of PLT1 (plt_base + 0x10) in GOT[1] and GOT[1] is stored in GOT[3]. We can undo prelink in GOT by computing the corresponding the pushq offset with GOT[1] + (GOT offset - &GOT[3]) * 2 Since for each entry in .plt except for PLT0 we create a 8-byte entry in .plt.bnd, there is extra 8-byte per PLT symbol. We also investigated the 16-byte entry for .plt.bnd. We compared the 8-byte entry vs the the 16-byte entry for .plt.bnd on Sandy Bridge. There are no performance differences in SPEC CPU 2000/2006 as well as micro benchmarks. Pros: No change to undo prelink in dynamic linker. Only 8-byte memory overhead for each PLT symbol. Cons: Extra .plt.bnd section is needed. Extra 8 byte for legacy branches to PLT. GDB is unware of the new layout of .plt and .plt.bnd. bfd/ * elf64-x86-64.c (elf_x86_64_bnd_plt0_entry): New.

We want __ehdr_start hidden before size_dynamic_sections so that it isn't put in .dynsym, but we do need the dynamic relocations for a PIE or shared library with a non-PIC reference. Defining it early is wrong if we don't actually define the symbol later to its proper value. (In some cases we want to leave the symbol undefined, for example, when the ELF header isn't loaded, and we don't have this infomation available in before_allocation.) * elf32-i386.c (elf_i386_allocate_dynrelocs): Revert the last change. * elf64-x86-64.c (elf_x86_64_allocate_dynrelocs): Likewise.
