| 2015-10-14 | Check mmap and read return values. While at it, remove unused duplicated file. | Tobias Stoeckmann | |
| ok millert@ | |||
| 2015-09-23 | Don't be too agressive write-protecting the GOT and PLT. If we have no clue | Mark Kettenis | |
| where they end, there is a good chance they are sharing a page with .data, which obviously needs to remain writable. So only attempt to make them read-only if we know they have a non-zero size. Original diff from guenther@ based on an earlier diff from me. Fixes ld -Z on alpha. ok miod@, guenther@ | |||
| 2015-09-19 | kbind has eliminated the need for and use of the bind lock. Delete it, the | Philip Guenther | |
| the callback, and the sigprocmask stub. Keep around the DL_SETBINDLCK case until libpthread stops using it. discussed with miod@ at l2k15 ok kettenis@ | |||
| 2015-09-19 | Remove PROT_EXEC bit from GOT_PERMS. ld.so doesn't need it anymore, and | Mark Kettenis | |
| rcrt0.o will add it for BSS-PLT binaries if necessary. ok guenther@ | |||
| 2015-09-19 | Make bootstrapping code compatible with the Secure-PLT ABI. | Mark Kettenis | |
| ok guenther@ | |||
| 2015-09-13 | Rename __sysctl syscall to just sysctl, as the userland wrapper is no longer | Philip Guenther | |
| necessary ok deraadt@ jsing@ | |||
| 2015-09-12 | Use kbind for lazy binding GOT/PLT updates on arm. | Philip Guenther | |
| While here add some gcc __predict hints. Much testing, discussion, pondering, and flailing from miod and deraadt ok miod@ | |||
| 2015-09-09 | Some explicit iflush instructions after the kbind() call are still needed | Miod Vallat | |
| for now; misunderstanding between guenther@ and me. | |||
| 2015-09-06 | Check strdup return value for NULL. | Tobias Stoeckmann | |
| ok millert@ | |||
| 2015-09-01 | Use kbind for lazy binding GOT/PLT updates on m88k and sparc. | Philip Guenther | |
| Much discussion with and assistance from miod and deraadt ok miod@ | |||
| 2015-08-31 | Add framework for resolving (pun intended) libc namespace issues, using | Philip Guenther | |
| wrapper .h files and asm labels to let internal calls resolve directly and not be overridable or use the PLT. Then, apply that framework to most of the functions in stdio.h, string.h, err.h, and wchar.h. Delete the should-have-been-hidden-all-along _v?(err|warn)[cx]? symbols while here. tests clean on i386, amd64, sparc64, powerpc, and mips64 naming feedback from kettenis@ and millert@ ok kettenis@ | |||
| 2015-08-28 | Use kbind for lazy binding GOT/PLT updates on sh (i.e. landisk) | Philip Guenther | |
| Much discussion with and assistance from miod and deraadt ok deraadt@ | |||
| 2015-08-28 | Use ELF_LDFLAGS to pass the --version-script argument such that we actually | Mark Kettenis | |
| hide symbols on all our architectures; hppa, hppa64 and sh override LDADD. LDADD isn't really the proper variable for passing linker flags anyway. ok guenther@, deraadt@ | |||
| 2015-08-27 | If we take the address of a function pointer, we might get a pointer to | Mark Kettenis | |
| a plabel instead of the entry-point address. In that case, get the entry-point address from the plabel. Makes ld.so work on hppa when _dl_bind_start gets hidden by the version script. ok miod@ | |||
| 2015-08-27 | Use kbind for lazy binding GOT/PLT updates on hppa. | Philip Guenther | |
| Much discussion with and assistance from miod and deraadt ok deraadt@ | |||
| 2015-08-26 | Kbind 3: The Legend Continues! | Philip Guenther | |
| Use kbind for lazy binding GOT/PLT updates on alpha and mips64. While here add some gcc __predict hints. Much discussion with and assistance from miod and deraadt ok deraadt@ | |||
| 2015-08-25 | Use kbind for lazy binding GOT/PLT updates on i386 and powerpc; still others | Philip Guenther | |
| to follow. While here add some gcc __predict hints. Much discussion with and assistance from miod and deraadt ok deraadt@ | |||
| 2015-08-23 | Apply a symbol export list to ld.so with just the expected dl*() and the | Philip Guenther | |
| two symbols needed by gdb. Remember: ld.so exports override those in shared libs. ok deraadt@ | |||
| 2015-08-23 | Use kbind for lazy binding GOT/PLT updates on amd64 and sparc64; others | Philip Guenther | |
| to follow. While here add some gcc __predict hints. Much discussion with and assistance from miod and deraadt ok deraadt@ | |||
| 2015-08-23 | Add support for the Secure-PLT ABI variant. This will give us better W^X | Mark Kettenis | |
| support on powerpc as it uses a non-executable GOT and PLT. "start slamming stuff in" deraadt@ | |||
| 2015-08-23 | spaces | Theo de Raadt | |
| 2015-08-23 | huge amount of spaces | Theo de Raadt | |
| 2015-08-18 | _dl_malloc() proto exists, do not cast result | Theo de Raadt | |
| 2015-08-17 | Add missing 'extern's to avoid introducing commons into *crt0.o | Philip Guenther | |
| ok miod@ kettenis@ | |||
| 2015-07-26 | Reenable the ld.so pre-install test; the "am I cross-compiling" test was | Philip Guenther | |
| too loose. Update the test to try to exercise the printf binding twice. ok miod@ | |||
| 2015-07-26 | Copy relocations can't be jump-slot relocations, so delete the test for that. | Philip Guenther | |
| ok miod@ | |||
| 2015-07-03 | Correctly handle relative-type relocations; very old ld.so bug which got | Miod Vallat | |
| fixed everywhere but on sparc for some unknown reason (and did not cause any havoc in real life). | |||
| 2015-06-10 | breath->breadth | Stuart Henderson | |
| 2015-06-10 | Typos: equalivant, fucntion, libary. | Miod Vallat | |
| 2015-06-03 | Do not assume that asprintf() clears the pointer on failure, which | Todd C. Miller | |
| is non-portable. Also add missing asprintf() return value checks. OK deraadt@ guenther@ doug@ | |||
| 2015-06-01 | In the lazy binding routine, make sure we actually allocate the stack we need, | Miod Vallat | |
| instead of corrupting the caller's stack by mistake. This fixes the mysterious segfaults in __powerpc_read_tcb() reported on earlier G3 systems - more recent processors have been luckier... ok deraadt@ | |||
| 2015-05-29 | Make ld.so on alpha cope with binaries built with secureplt (where secure here | Miod Vallat | |
| means read-only, which our ld.so already enforced, but a smaller plt section). | |||
| 2015-05-26 | Better cross-compilation check | Miod Vallat | |
| 2015-05-22 | be pedantic with sizeof use | Jonathan Gray | |
| no change in behaviour as sizeof(char **) is the same as sizeof(char *) ok otto@ guenther@ | |||
| 2015-05-06 | Fix a memory leak in _dl_load_dep_libs() | Jonathan Gray | |
| ok otto@ guenther@ | |||
| 2015-04-28 | tidy up the prebind text; prompted by zhuk | Jason McIntyre | |
| 2015-02-08 | Fix cross-build. OK jsing@ miod@ guenther@ deraadt@ | Masao Uebayashi | |
| 2015-02-06 | Raise ELF_RANDOMIZE_LIMIT to 64K, so that programs and libraries can | Theo de Raadt | |
| legitimately use random section variables without execve failures... Because this section is not demand faulted, yield() every page during the fill otherwise the costs are charged poorly. ok tedu matthew | |||
| 2015-01-22 | delete annoying white space that annoy | Theo de Raadt | |
| 2015-01-20 | If _dl_progname exceeds half the syslog buffer, truncate it with "...", | Theo de Raadt | |
| so that the remaining information is more visible ok kettenis miod | |||
| 2015-01-20 | Add support for tracing libraries in static PIE binaries. rcrt does not | Theo de Raadt | |
| contain "LD_TRACE_LOADED_OBJECTS" support, so this gets done by calling RTLD_TRACE directly. ok guenther | |||
| 2015-01-19 | gcc does not understand that the loop conditionally sets bsod before | Theo de Raadt | |
| using it, so it warns... Copy the warning silencing code from the same function in ../ld.so | |||
| 2015-01-18 | do not require <a.out.h> | Theo de Raadt | |
| 2015-01-16 | <sys/param.h> to <limits.h> conversion. Verified binaries | Theo de Raadt | |
| ok millert, thanks to doug for process advice | |||
| 2014-12-30 | self-relocating crt0 bits for sh, and enable static pie by default. With some | Miod Vallat | |
| archdep.h help from kettenis@ | |||
| 2014-12-30 | Clean up and optimize _dl_start a bit by using immediate addressing for | Miod Vallat | |
| the constants whenever they fit, and avoiding saving and restoring registers we don't need to preserve. | |||
| 2014-12-30 | Fix handling of R_MIPS_REL32_64 relocations that reference a symbol. | Mark Kettenis | |
| Fixes remaining problems with static PIE on mips64. | |||
| 2014-12-27 | Static PIE for mips64. Still something not quite right as a full make build | Mark Kettenis | |
| fails. ok kurt@ | |||
| 2014-12-27 | Make ld.so process only R_ALPHA_RELATIVE relocations during early GOT | Mark Kettenis | |
| relocation in _reloc_alpha_got(), and teach RELOC_RELA() to skip R_ALPHA_NONE relocations (which are just nops used to fill out the relocation table). Handling R_ALPHA_NONE relocations will be necessary for static PIE support and it is not inconceivable that ld.so will end up with such relocations at some point. ok kurt@ | |||
| 2014-12-24 | Expand Elf_Rel relocations to include DT_JMPREL. Inspect DT_PLTREL value | Kurt Miller | |
| to determine if DT_JMPREL relocations are REL or RELA and conditionally perform DT_JMPREL in either REL or RELA as needed (idea from kettenis@). Remove unneeded i386 RELA implementation. i386 static pie working now. okay kettenis@ | |||
