+newer versions of gcc generate relocations in the elf_get_dynamic_info func |
50 |
+which glibc relies on to populate some info structs. those structs are then |
51 |
+used by ldso to process relocations in itself. glibc requires that there are |
52 |
+no relocations until that point (*after* elf_get_dynamic_info), so we end up |
53 |
+crashing during elf_get_dynamic_info because the relocation has not yet been |
54 |
+processed. |
55 |
+ |
56 |
+this hack shuffles the code in a way that tricks gcc into not generating the |
57 |
+relocation. we need to figure out something better for upstream. |

+# Note [Disable automatic stripping] |
731 |
+# Disabling automatic stripping for a few reasons: |
732 |
+# - portage's attempt to strip breaks non-native binaries at least on |
733 |
+# arm: bug #697428 |
734 |
+# - portage's attempt to strip libpthread.so.0 breaks gdb thread |
735 |
+# enumeration: bug #697910. This is quite subtle: |
736 |
+# * gdb uses glibc's libthread_db-1.0.so to enumerate threads. |
737 |
+# * libthread_db-1.0.so needs access to libpthread.so.0 local symbols |
738 |
+# via 'ps_pglobal_lookup' symbol defined in gdb. |
739 |
+# * 'ps_pglobal_lookup' uses '.symtab' section table to resolve all |
740 |
+# known symbols in 'libpthread.so.0'. Specifically 'nptl_version' |
741 |
+# (unexported) is used to sanity check compatibility before enabling |
742 |
+# debugging. |
743 |
+# Also see https://sourceware.org/gdb/wiki/FAQ#GDB_does_not_see_any_threads_besides_the_one_in_which_crash_occurred.3B_or_SIGTRAP_kills_my_program_when_I_set_a_breakpoint |
744 |
+# * normal 'strip' command trims '.symtab' |
745 |
+# Thus our main goal here is to prevent 'libpthread.so.0' from |
746 |
+# losing it's '.symtab' entries. |
747 |
+# As Gentoo's strip does not allow us to pass less aggressive stripping |
748 |
+# options and does not check the machine target we strip selectively. |
749 |
+ |
750 |
+# We need a new-enough binutils/gcc to match upstream baseline. |
751 |
+# Also we need to make sure our binutils/gcc supports TLS, |
752 |
+# and that gcc already contains the hardened patches. |
753 |
+# Lastly, let's avoid some openssh nastiness, bug 708224, as |
754 |
