* Bug 20292 - Simplify and test _dl_addr_inside_objectCarlos O'Donell2016-09-305-35/+309
| | | | | | | | The function _dl_addr_inside_object is simplified by removing the conditional 'reladdr - l->l_phdr[n].p_vaddr >= 0' which is always true. The function is refactored into it's own object file and a unit test added to verify the correct behaviour of the function.
* [PR19826] fix non-LE TLS in static programsAlexandre Oliva2016-09-212-0/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | An earlier fix for TLS dropped early initialization of DTV entries for modules using static TLS, leaving it for __tls_get_addr to set them up. That worked on platforms that require the GD access model to be relaxed to LE in the main executable, but it caused a regression on platforms that allow GD in the main executable, particularly in statically-linked programs: they use a custom __tls_get_addr that does not update the DTV, which fails when the DTV early initialization is not performed. In static programs, __libc_setup_tls performs the DTV initialization for the main thread, but the DTV of other threads is set up in _dl_allocate_tls_init, so that's the fix that matters. Restoring the initialization in the remaining functions modified by this patch was just for uniformity. It's not clear that it is ever needed: even on platforms that allow GD in the main executable, the dynamically-linked version of __tls_get_addr would set up the DTV entries, even for static TLS modules, while updating the DTV counter. for ChangeLog [BZ #19826] * elf/dl-tls.c (_dl_allocate_tls_init): Restore DTV early initialization of static TLS entries. * elf/dl-reloc.c (_dl_nothread_init_static_tls): Likewise. * nptl/allocatestack.c (init_one_static_tls): Likewise.

* Set NODELETE flag after checking for NULL pointerAurelien Jarno2016-09-033-7/+81
| | | | | | | | | | | | | | The commit b632bdd3 moved the setting of the DF_1_NODELETE flag earlier in the dl_open_worker function. However when calling dlopen with both RTLD_NODELETE and RTLD_NOLOAD, the pointer returned by _dl_map_object is NULL. This condition is checked just after setting the flag, while it should be done before. Fix that. Changelog: [BZ #19810] * elf/dl-open.c (dl_open_worker): Set DF_1_NODELETE flag later. * elf/tst-noload.c: New test case. * elf/Makefile (tests): Add tst-noload.
* elf: Do not use memalign for TCB/TLS blocks allocation [BZ #17730]Florian Weimer2016-08-031-36/+53
| | | | | | | | | | | | | | | | | | | Instead, call malloc and explicitly align the pointer. There is no external location to store the original (unaligned) pointer, and this commit increases the allocation size to store the pointer at a fixed location relative to the TCB pointer. The manual alignment means that some space goes unused which was previously made available for subsequent allocations. However, in the TLS_DTV_AT_TP case, the manual alignment code avoids aligning the pre-TCB to the TLS block alignment. (Even while using memalign, the allocation had some unused padding in front.) This concludes the removal of memalign calls from the TLS code, and the new tst-tls3-malloc test verifies that only core malloc routines are used.
* elf: Avoid using memalign for TLS allocations [BZ #17730]Florian Weimer2016-08-031-29/+46
| | | | | | | | | | | | Instead of a flag which indicates the pointer can be freed, dtv_t now includes the pointer which should be freed. Due to padding, the size of dtv_t does not increase. To avoid using memalign, the new allocate_dtv_entry function allocates a sufficiently large buffer so that a sub-buffer can be found in it which starts with an aligned pointer. Both the aligned and original pointers are kept, the latter for calling free later.
* elf: dl-minimal malloc needs to respect fundamental alignmentFlorian Weimer2016-08-031-1/+2
| | | | | | | | | | | | | | The dynamic linker currently uses __libc_memalign for TLS-related allocations. The goal is to switch to malloc instead. If the minimal malloc follows the ABI fundamental alignment, we can assume that malloc provides this alignment, and thus skip explicit alignment in a few cases as an optimization. It was requested on libc-alpha that MALLOC_ALIGNMENT should be used, although this results in wasted space if MALLOC_ALIGNMENT is larger than the fundamental alignment. (The dynamic linker cannot assume that the non-minimal malloc will provide an alignment of MALLOC_ALIGNMENT; the ABI provides _Alignof (max_align_t) only.)

* Treat STV_HIDDEN and STV_INTERNAL symbols as STB_LOCALMaciej W. Rozycki2016-07-013-1/+7
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In a reference to PR ld/19908 make ld.so respect symbol export classes aka visibility and treat STV_HIDDEN and STV_INTERNAL symbols as local, preventing such symbols from preempting exported symbols. According to the ELF gABI[1] neither STV_HIDDEN nor STV_INTERNAL symbols are supposed to be present in linked binaries: "A hidden symbol contained in a relocatable object must be either removed or converted to STB_LOCAL binding by the link-editor when the relocatable object is included in an executable file or shared object." "An internal symbol contained in a relocatable object must be either removed or converted to STB_LOCAL binding by the link-editor when the relocatable object is included in an executable file or shared object." however some GNU binutils versions produce such symbols in some cases. PR ld/19908 is one and we also have this note in scripts/abilist.awk: so clearly there is linked code out there which contains such symbols which is prone to symbol table misinterpretation, and it'll be more productive if we handle this gracefully, under the Robustness Principle: "be liberal in what you accept, and conservative in what you produce", especially as this is a simple (STV_HIDDEN|STV_INTERNAL) => STB_LOCAL mapping.

* Reduce number of mmap calls from __libc_memalign in ld.soH.J. Lu2016-04-231-7/+5
| | | | | | | | | | | | | | | | | __libc_memalign in ld.so allocates one page at a time and tries to optimize consecutive __libc_memalign calls by hoping that the next mmap is after the current memory allocation. However, the kernel hands out mmap addresses in top-down order, so this optimization in practice never happens, with the result that we have more mmap calls and waste a bunch of space for each __libc_memalign. This change makes __libc_memalign to mmap one page extra. Worst case, the kernel never puts a backing page behind it, but best case it allows __libc_memalign to operate much much better. For elf/tst-align --direct, it reduces number of mmap calls from 12 to 9. * elf/dl-minimal.c (__libc_memalign): Mmap one extra page.

* Enable --localedir to set message catalog directory (Bug 14259)Carlos O'Donell2016-02-241-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In 1999 the project split "localedir" into "localedir" (path to compiled locale archives) and "msgcatdir" (path to message catalogs). This predates the 2002 change in the GNU Coding Standard to document the use of "localedir" for the path to the message catalogs. It appears that newlib, gcc, and several other projects also used "msgcatdir" at one point or another in the past, and so it is in line with historical precedent that glibc would also use "msgcatdir." However, given that the GNU Coding Standard uses "localedir", we will switch to that for consistency as a GNU project. Previous uses of --localdir didn't work anyway (see bug 14259). I am committing this patch in the understanding that nobody would object to fixing #14259 as part of aligning our variable usage to the GNU Coding Standard. Given that previous "localedir" uses were converted to "complocaledir" by [1], we can now convert "msgcatdir" to "localedir" and complete the transition. With an addition to config.make.in we also fix bug 14259 and allow users to specify the locale dependent data directory with "--localedir" at configure time. There is still no way to control at configure time the location of the *compiled* locale directory. Tested on x86_64 with no regressions. Tested using "--localedir" to specify alternate locale dependent data directory and verified with "make install DESTDIR=/tmp/glibc". [1] 90fe682d3067163aa773feecf497ef599429457a

* _dl_fini: Rewrite to use VLA instead of extend_allocaFlorian Weimer2015-10-291-104/+89
| | | | | | | | | | | | | | In this case, extend_alloca is used to work around the lack of deallocation on scope exit. A VLA is automatically deallocated in this way, so it is the more fitting approach. To implement this, it is necessary to eliminate the goto. In addition, this change eliminates the trivially-true assert; the assert is always skipped if nloaded > 0. * elf/dl-fini.c (_dl_fini): Rewrite to use variable-length array instead of extend_alloca.

This mostly automatically-generated patch converts 113 function definitions in glibc from old-style K&R to prototype-style. Following my other recent such patches, this one deals with the case of function definitions in files that either contain assertions or where grep suggested they might contain assertions - and thus where it isn't possible to use a simple object code comparison as a sanity check on the correctness of the patch, because line numbers are changed. A few such automatically-generated changes needed to be supplemented by manual changes for the result to compile. openat64 had a prototype declaration with "..." but an old-style definition in sysdeps/unix/sysv/linux/dl-openat64.c, and "..." needed adding to the generated prototype in the definition (I've filed <https://gcc.gnu.org/bugzilla/show_bug.cgi?id=68024> for diagnosing such cases in GCC; the old state was undefined behavior not requiring a diagnostic, but one seems a good idea). In addition, as Florian has noted regparm attribute mismatches between declaration and definition are only diagnosed for prototype definitions, and five functions needed internal_function added to their definitions (in the case of __pthread_mutex_cond_lock, via the macro definition of __pthread_mutex_lock) to compile on i386. After this patch is in, remaining old-style definitions are probably most readily fixed manually before we can turn on -Wold-style-definition for all builds.

* Remove gnu_unique_object configure test.Joseph Myers2015-10-196-14/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There is a configure test for assembler support for the gnu_unique_object symbol type. This support was added in binutils 2.20, so is present in all versions supported for building glibc. Thus, I think the configure test can be removed; this patch does so. Now, there is a caveat that the gas NEWS entry refers to this as a feature for GNU/Linux targets. But the condition is use of ELFOSABI_GNU or ELFOSABI_NONE. ELFOSABI_GNU covers Hurd as well as GNU/Linux (as was the case with the older ELFOSABI_LINUX name), and ELFOSABI_NONE means this is effectively OS-independent. Furthermore, I think a correct binutils port for any glibc target ought to support this feature for use with glibc; glibc supports this as an OS-independent feature (the configure test is only about glibc testcases). Tested for x86_64 (testsuite, and that installed shared libraries are unchanged by the patch). * configure.ac (libc_cv_asm_unique_object): Remove configure test. * configure: Regenerated. * config.h.in (HAVE_ASM_UNIQUE_OBJECT): Remove #undef. * elf/tst-unique1.c (do_test) [HAVE_ASM_UNIQUE_OBJECT]: Make code unconditional. * elf/tst-unique1mod1.c [HAVE_ASM_UNIQUE_OBJECT]: Likewise. * elf/tst-unique1mod2.c [HAVE_ASM_UNIQUE_OBJECT]: Likewise. * elf/tst-unique2.c (do_test) [HAVE_ASM_UNIQUE_OBJECT]: Likewise.

This conversion is deliberately simplistic, excluding any tricky cases as even a patch covering only simple cases is still very large. Currently excluded are: sysdeps files (to improve test coverage for the initial patch); files containing assertions (to avoid line number changes so that generated libraries can be compared); any cases where the generated function declaration would involve lines over 79 characters and so need to be wrapped; any cases with array parameters or other cases where parameter declarators don't end with the parameter name; any other cases that my script didn't parse. I didn't try to make the ChangeLog generation indicate when function definitions are conditional; it just lists the functions changed without regard to that.

The result is much easier to read as expected from the ALIGN_* cleanups.
* Move bits/libc-lock.h and bits/libc-lockP.h out of bits/ (bug 14912).Joseph Myers2015-09-087-7/+7

This patch renames bits/libc-lock.h to plain libc-lock.h and bits/libc-lockP.h to plain libc-lockP.h to follow that convention. Note that I don't know where libc-lockP.h comes from for Hurd (the Hurd libc-lock.h includes libc-lockP.h, but the only libc-lockP.h in the glibc source tree is for NPTL) - some unmerged patch? - but I updated the #include in the Hurd libc-lock.h anyway.

* Fix dynamic linker issue with bind-nowPetar Jovanovic2015-08-191-6/+8
| | | | | | | | | | | | | | Fix the bind-now case when DT_REL and DT_JMPREL sections are separate and there is a gap between them. [BZ #14341] * elf/dynamic-link.h (elf_machine_lazy_rel): Properly handle the case when there is a gap between DT_REL and DT_JMPREL sections. * sysdeps/x86_64/Makefile (tests): Add tst-split-dynreloc. (LDFLAGS-tst-split-dynreloc): New. (tst-split-dynreloc-ENV): Likewise. * sysdeps/x86_64/tst-split-dynreloc.c: New file. * sysdeps/x86_64/tst-split-dynreloc.lds: Likewise.
* Fix -Wundef warnings in elf/tst-execstack.c.Joseph Myers2015-08-191-0/+1
| | | | | | | | | | | | | | | | | | | | | | To remove -Wno-error=undef, we need to fix the remaining cases where there are -Wundef warnings in the testsuite. One of those places is in elf/tst-execstack.c. tst-execstack.c tests USE_PTHREADS with #if. nptl/tst-execstack.c defines USE_PTHREADS to 1 before including ../elf/tst-execstack.c, while elf/tst-execstack.c, when compiled directly, leaves it undefined. This patch adds a setting of CPPFLAGS-tst-execstack.c to elf/Makefile. An alternative approach would be to rename tst-execstack.c to tst-execstack-main.c and have two different tst-execstack.c files include it, each with an appropriate USE_PTHREADS #define. Tested for x86_64. * elf/Makefile [$(have-z-execstack) = yes] (CPPFLAGS-tst-execstack.c): New variable.
