This makes the calls done through these +slots invalid, because the special first PLT slot is not initialized, +and dynamic linker SIGSEGVs because of this. Ltrace relies on +arranging breakpoints such that the dynamic linker is not actually +entered, and moves PC around itself to simulate the effects of a call +through PLT. + +Originally, arch_elf_add_plt_entry was called only for symbols that +were actually traced. Later this was changed and it's now called for +all PLT entries, and the resulting candidate list is filtered +afterwards. This gives backends a chance to rename the symbol, as is +useful with IRELATIVE PLT calls, where symbol name may not be +available at all. But the PPC backend was never updated to reflect +this, and unresolved all symbols for which arch_elf_add_plt_entry was +called, thus rendering _all_ PLT slots invalid, even those that +weren't later procted by breakpoints. Thus calls done through any +untraced slots failed. + +This patch fixes this problem by deferring the unprelinking of PLT +slots into the on_install hook of breakpoints. +--- + sysdeps/linux-gnu/ppc/arch.h | 21 ++++++++- + sysdeps/linux-gnu/ppc/plt.c | 94 ++++++++++++++++++++++++++++++++++--------- + 2 files changed, 94 insertions(+), 21 deletions(-) + +Index: b/sysdeps/linux-gnu/ppc/arch.h +=================================================================== +--- a/sysdeps/linux-gnu/ppc/arch.h ++++ b/sysdeps/linux-gnu/ppc/arch.h +@@ -1,6 +1,6 @@ + /* + * This file is part of ltrace. +- * Copyright (C) 2012 Petr Machata ++ * Copyright (C) 2012,2013,2014 Petr Machata + * Copyright (C) 2006 Paul Gilliam + * Copyright (C) 2002,2004 Juan Cespedes + * +@@ -120,12 +120,29 @@ enum ppc64_plt_type { + /* Very similar to PPC_PLT_UNRESOLVED, but for JMP_IREL + * slots. */ + PPC_PLT_IRELATIVE, ++ ++ /* Transitional state before the breakpoint is enabled. */ ++ PPC_PLT_NEED_UNRESOLVE, + }; + + #define ARCH_HAVE_LIBRARY_SYMBOL_DATA ++struct ppc_unresolve_data; + struct arch_library_symbol_data { + enum ppc64_plt_type type; +- GElf_Addr resolved_value; ++ ++ /* State Contents ++ * ++ * PPC_DEFAULT N/A ++ * PPC64_PLT_STUB N/A ++ * PPC_PLT_UNRESOLVED PLT entry address. ++ * PPC_PLT_IRELATIVE Likewise. ++ * PPC_PLT_RESOLVED The original value the slot was resolved to. ++ * PPC_PLT_NEED_UNRESOLVE DATA. ++ */ ++ union { ++ GElf_Addr resolved_value; ++ struct ppc_unresolve_data *data; ++ }; + + /* Address of corresponding slot in .plt. */ + GElf_Addr plt_slot_addr; +Index: b/sysdeps/linux-gnu/ppc/plt.c +=================================================================== +--- a/sysdeps/linux-gnu/ppc/plt.c ++++ b/sysdeps/linux-gnu/ppc/plt.c +@@ -715,6 +715,14 @@ unresolve_plt_slot(struct Process *proc, + return 0; + } + ++struct ppc_unresolve_data { ++ struct ppc_unresolve_data *self; /* A canary. */ ++ GElf_Addr plt_entry_addr; ++ GElf_Addr plt_slot_addr; ++ GElf_Addr plt_slot_value; ++ bool is_irelative; ++}; ++ + enum plt_status + arch_elf_add_plt_entry(struct Process *proc, struct ltelf *lte, + const char *a_name, GElf_Rela *rela, size_t ndx, +@@ -816,28 +824,23 @@ arch_elf_add_plt_entry(struct Process *p + && (plt_slot_value == plt_entry_addr || plt_slot_value == 0)) { + libsym->arch.type = PPC_PLT_UNRESOLVED; + libsym->arch.resolved_value = plt_entry_addr; +- + } else { +- /* Unresolve the .plt slot.
