* 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.
* Register extra test objectsAndreas Schwab2016-04-131-2/+3

* sln: use stat64Hongjiu Zhang2016-03-071-2/+2
| | | | | | | | | | | | | When using sln on some filesystems which return 64-bit inodes, the stat call might fail during install like so: .../elf/sln .../elf/symlink.list /lib32/libc.so.6: invalid destination: Value too large for defined data type /lib32/ld-linux.so.2: invalid destination: Value too large for defined data type Makefile:104: recipe for target 'install-symbolic-link' failed Switch to using stat64 all the time to avoid this.

* 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

* Keep only ELF_RTYPE_CLASS_{PLT|COPY} bits for prelinkH.J. Lu2015-11-071-2/+19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | prelink runs ld.so with the environment variable LD_TRACE_PRELINKING set to dump the relocation type class from _dl_debug_bindings. prelink has the following relocation type classes: #define RTYPE_CLASS_VALID 8 #define RTYPE_CLASS_PLT (8|1) #define RTYPE_CLASS_COPY (8|2) #define RTYPE_CLASS_TLS (8|4) where ELF_RTYPE_CLASS_EXTERN_PROTECTED_DATA has a conflict with RTYPE_CLASS_TLS. Since prelink only uses ELF_RTYPE_CLASS_PLT and ELF_RTYPE_CLASS_COPY bits, we should clear the other bits when the DL_DEBUG_PRELINK bit is set. [BZ #19178] * elf/dl-lookup.c (RTYPE_CLASS_VALID): New.

* _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. Change control flow to avoid a goto. Remove assert which is trivially always true.

* Convert 113 more function definitions to prototype style (files with ↵Joseph Myers2015-10-201-5/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | assertions). 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. Tested for x86_64 and x86 (testsuite, and that installed stripped shared libraries are unchanged by the patch). * crypt/cert.c (good_bye): Convert to prototype-style function definition.

| | | | | | | | | | | | | | | | | | | | | | 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.

* Clear DF_1_NODELETE flag only for failed to load library.Maxim Ostapenko2015-08-114-10/+56
| | | | | | | | | | | | | | | | | | | | | | | | https://sourceware.org/bugzilla/show_bug.cgi?id=18778 If dlopen fails to load an object that has triggered loading libpthread it causes ld.so to unload libpthread because its DF_1_NODELETE flags has been forcefully cleared. The next call to __rtdl_unlock_lock_recursive will crash since pthread_mutex_unlock no longer exists. This patch moves l->l_flags_1 &= ~DF_1_NODELETE out of loop through all loaded libraries and performs the action only on inconsistent one. [BZ #18778] * elf/Makefile (tests): Add Add tst-nodelete2.

* Modify several tests to use test-skeleton.cArjun Shankar2015-08-063-6/+15
| | | | | | | | | These tests were skipped by the use-test-skeleton conversion done in commit 29955b5d because they did not have an `int main (void)' declaration. Instead their `main' functions were declared with arguments (i.e. argc, argv) even though they didn't use them. Remove these arguments and include the test skeleton in these tests.
* Also use l_tls_dtor_count to decide on object unload (BZ #18657)Siddhesh Poyarekar2015-07-231-1/+8
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When an TLS destructor is registered, we set the DF_1_NODELETE flag to signal that the object should not be destroyed. We then clear the DF_1_NODELETE flag when all destructors are called, which is wrong - the flag could have been set by other means too. This patch replaces this use of the flag by using l_tls_dtor_count directly to determine whether it is safe to unload the object. This change has the added advantage of eliminating the lock taking when calling the destructors, which could result in a deadlock. The patch also fixes the test case tst-tls-atexit - it was making an invalid dlclose call, which would just return an error silently. I have also added a detailed note on concurrency which also aims to justify why I chose the semantics I chose for accesses to l_tls_dtor_count. Thanks to Torvald for his help in getting me started on this and (literally) teaching my how to approach the problem. Change verified on x86_64; the test suite does not show any regressions due to the patch. ChangeLog: [BZ #18657] * elf/dl-close.c (_dl_close_worker): Don't unload DSO if there are pending TLS destructor calls. * include/link.h (struct link_map): Add concurrency note for L_TLS_DTOR_COUNT. * stdlib/cxa_thread_atexit_impl.c (__cxa_thread_atexit_impl): Don't touch the link map flag. Atomically increment l_tls_dtor_count. (__call_tls_dtors): Atomically decrement l_tls_dtor_count. Avoid taking the load lock and don't touch the link map flag. * stdlib/tst-tls-atexit-nodelete.c: New test case. * stdlib/Makefile (tests): Use it. * stdlib/tst-tls-atexit.c (do_test): dlopen tst-tls-atexit-lib.so again before dlclose. Add conditionals to allow tst-tls-atexit-nodelete test case to use it.
* hppa/ia64: _dl_symbol_address: add PLT bypass for rtldMike Frysinger2015-07-161-0/+1
| | | | | | | | | | This symbol is defined in the ldso, and is used both there and libc.so. There is no hidden symbol for it though which leads to relocations in the ldso and the elf/check-localplt test failing. Add a hidden def for rtld to fix all of that. This function/file is only used by hppa & ia64, so no testing is needed for other arches.

* Set NODELETE flag when opening already open objects with RTLD_NODELETESiddhesh Poyarekar2015-07-164-7/+96
| | | | | | | | | | | | | | | | The DF_1_NODELETE flag is set too late when opening a DSO, due to which, if a DSO is already open, subsequently opening it with RTLD_NODELETE fails to set the DF_1_NODELETE flag. This patch fixes this by setting the flag immediately after bumping the opencount. Verified on x86_64. [BZ #18676] * elf/tst-nodelete-opened.c: New test case. * elf/tst-nodelete-opened-lib.c: New test case module. * elf/Makefile (tests, modules-names): Use them. * elf/dl-open.c (dl_open_worker): Set DF_1_NODELETE flag early.

* Add forced deletion support to _dl_close_workerPavel Kopyl2015-07-078-5/+130
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | https://sourceware.org/bugzilla/show_bug.cgi?id=17833 I've a shared library that contains both undefined and unique symbols. Then I try to call the following sequence of dlopen: 1. dlopen("./libfoo.so", RTLD_NOW) 2. dlopen("./libfoo.so", RTLD_LAZY | RTLD_GLOBAL) First dlopen call terminates with error because of undefined symbols, but STB_GNU_UNIQUE ones set DF_1_NODELETE flag and hence block library in the memory. The library goes into inconsistent state as several structures remain uninitialized. For instance, relocations for GOT table were not performed. By the time of second dlopen call this library looks like as it would be fully initialized but this is not true: any call through incorrect GOT table leads to segmentation fault. On some systems this inconsistency triggers assertions in the dynamic linker. This patch adds a parameter to _dl_close_worker to implement forced object deletion in case of dlopen() failure: 1. Clears DF_1_NODELETE bit if forced, to allow library to be removed from memory. 2. For each unique symbol that is defined in this object clears appropriate entry in _ns_unique_sym_table.

* Support compilers defaulting to PIEH.J. Lu2015-06-251-0/+1
| | | | | | | | | | | | | | | | | To support building glibc with GCC 6 configured with --enable-default-pie, which generates PIE by default, we need to build programs as PIE. But elf/tst-dlopen-aout must not be built as PIE since it tests dlopen on ET_EXEC file and PIE is ET_DYN. [BZ #17841] * Makeconfig (no-pie-ldflag): New. (+link): Set to $(+link-pie) if default to PIE. (+link-tests): Set to $(+link-pie-tests) if default to PIE. * config.make.in (build-pie-default): New. * configure.ac (libc_cv_pie_default): New. Set to yes if -fPIE is default. AC_SUBST. * configure: Regenerated. * elf/Makefile (LDFLAGS-tst-dlopen-aout): New.
