2016-12-09support: Introduce new subdirectory for test infrastructureFlorian Weimer
The new test driver in <support/test-driver.c> has feature parity with the old one. The main difference is that its hooking mechanism is based on functions and function pointers instead of macros. This commit also implements a new environment variable, TEST_COREDUMPS, which disables the code which disables coredumps (that is, it enables them if the invocation environment has not disabled them). <test-skeleton.c> defines wrapper functions so that it is possible to use existing macros with the new-style hook functionality. This commit changes only a few test cases to the new test driver, to make sure that it works as expected.
2016-12-02Bug 20918 - Building with --enable-nss-crypt fails tst-linkall-staticCarlos O'Donell
Some configurations may use NSS cryptographic routines but have no static library for those routines. The following changes allow glibc to be built and tested with --enable-nss-crypt, but without having a static NSS library. At a high level the change does two things: (1) Detect at configure time if static NSS crypto libraries are available. Assumes libfreebl3.a (instead of the existing Fedora libfreebl.a which is incomplete) which matches libfreebl3.so. (2) If static NSS crypto libraries are _not_ available then adjust the way in which we build tst-linkall-static. This includes excluding a reference to crypt and not linking against libcrypt.a, all of which will fail otherwise. Testing assumptions: * Static library is named libfreebl3.a (not libfreebl.a as is currently provided in Fedora), matching libfreebl3.so shared link name. Tested on x86_64 on Fedora with: (a) --enable-nss-crypt, with no static NSS library support: PASS (previous FAIL) (b) --enable-nss-crypt, with faked static NSS library support: PASS (unsupported) * Requires changing elf/Makefile to include a stub /lib64/libfreebl3.a for testing purposes. (c) --disable-nss-crypt: PASS (default) No regressions on x86_64. For details see: https://www.sourceware.org/ml/libc-alpha/2016-11/msg00647.html
2016-12-02elf/tst-tls-manydynamic: New testFlorian Weimer
This test adds coverage for creating many dynamic TLS variables which exhaust the static TLS allocation.
2016-12-02Fix new testcase elf/tst-latepthread on s390x.Stefan Liebler
The first dlopen ("tst-latepthreadmod.so", RTLD_LOCAL | RTLD_LAZY) call in elf/tst-latepthread.c fails on s390x with "error: dlopen failed: .../build-s390x/elf/tst-latepthreadmod.so: undefined symbol: this_function_is_not_defined". In elf/tst-latepthreadmod.c, this_function_is_not_defined is a sibling call which leads to a R_390_GLOB_DAT relocation in .rela.dyn instead of a R_390_JMP_SLOT in .rela.plt. As RTLD_LAZY skips the JMP_SLOT relocations, but not GLOB_DAT ones, the dlopen call fails. If elf/tst-latepthreadmod.c is build with -fno-optimize-sibling-calls, a JMP_SLOT relocation is generated for this_function_is_not_defined and the test passes. ChangeLog: * elf/Makefile (CFLAGS-tst-latepthreadmod.c): Add -fno-optimize-sibling-calls.
2016-11-30Implement _dl_catch_error, _dl_signal_error in libc.so [BZ #16628]Florian Weimer
This change moves the main implementation of _dl_catch_error, _dl_signal_error to libc.so, where TLS variables can be used directly. This removes a writable function pointer from the rtld_global variable. For use during initial relocation, minimal implementations of these functions are provided in ld.so. These are eventually interposed by the libc.so implementations. This is implemented by compiling elf/dl-error-skeleton.c twice, via elf/dl-error.c and elf/dl-error-minimal.c. As a side effect of this change, the static version of dl-error.c no longer includes support for the _dl_signal_cerror/_dl_receive_error mechanism because it is only used in ld.so.

2016-09-30Bug 20292 - Simplify and test _dl_addr_inside_objectCarlos O'Donell
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.
2016-09-03Set NODELETE flag after checking for NULL pointerAurelien Jarno
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.

2016-02-24Enable --localedir to set message catalog directory (Bug 14259)Carlos O'Donell
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

2015-09-03Mark elf/tst-protected1[ab] as XFAIL.Roland McGrath
2015-08-19Fix -Wundef warnings in elf/tst-execstack.c.Joseph Myers
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 [$(have-z-execstack) = yes] (CPPFLAGS-tst-execstack.c): New variable.
2015-08-11Clear DF_1_NODELETE flag only for failed to load library.Maxim Ostapenko
https://sourceware.org/bugzilla/show_bug.cgi?id=18778 If dlopen fails to load an object that has triggered loading libpthread it causes ld.so to unload libpthread because its DF_1_NODELETE flags has been forcefully cleared. The next call to __rtdl_unlock_lock_recursive will crash since pthread_mutex_unlock no longer exists. This patch moves l->l_flags_1 &= ~DF_1_NODELETE out of loop through all loaded libraries and performs the action only on inconsistent one. [BZ #18778] * elf/Makefile (tests): Add Add tst-nodelete2. (modules-names): Add tst-nodelete2mod. (tst-nodelete2mod.so-no-z-defs): New. ($(objpfx)tst-nodelete2): Likewise. ($(objpfx)tst-nodelete2.out): Likewise.

2015-07-16Set NODELETE flag when opening already open objects with RTLD_NODELETESiddhesh Poyarekar
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.

2015-07-07Add forced deletion support to _dl_close_workerPavel Kopyl
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.

To support building glibc with GCC 6 configured with --enable-default-pie, which generates PIE by default, we need to build programs as PIE.

2014-11-24Remove IS_IN_ldconfigSiddhesh Poyarekar
Replace with IS_IN (ldconfig). No change in generated code. * elf/Makefile (CFLAGS-ldconfig.c): Remove definition of IS_IN_ldconfig. * sysdeps/unix/sysv/linux/x86_64/dl-procinfo.c: Use IS_IN. * sysdeps/unix/sysv/linux/x86_64/dl-procinfo.h: Likewise.
2014-11-24Define IN_MODULE for translation units that define NOT_IN_libcSiddhesh Poyarekar
Make sure that all instances where NOT_IN_libc is defined also defines IN_MODULE to facilitate removal NOT_IN_libc in future passes. Verified that the generated code is unchanged on x86_64. * elf/Makefile (libof-sotruss-lib): Set as extramodules.
2014-11-24Remove IN_LIBSiddhesh Poyarekar
Replace with IS_IN and IS_IN_LIB macros instead. This change results in a change in generated code, because it fixes a subtle bug. The bug was introduced when systemtap probes were added to lowlevellock.h, which resulted in stap-probe.h being included in a number of places. stap-probe.h always defines IN_LIB, which breaks a check in errno.h and netdb.h since they rely on that macro to decide whether to implement an internal version of a declaration or an external one. The components that see a code change due to this are: iconv_prog libmemusage.so libpcprofile.so libSegFault.so libutil.so.1 locale localedef nscd All other built components (i.e. libc, libpthread, etc.) remain unchanged by this on x86_64. * elf/Makefile (CPPFLAGS-.os): Remove IN_LIB. * elf/rtld-Rules (rtld-CPPFLAGS): Likewise. * extra-lib.mk (CPPFLAGS-$(lib)): Likewise. * include/libc-symbols.h (IS_IN_LIB): New macro. * include/errno.h: Use IS_IN_LIB instead of IN_LIB. * include/netdb.h: Likewise. * include/stap-probe.h: Remove all uses of IN_LIB.
2014-11-19Add new macro IN_MODULE to identify module in which source is builtSiddhesh Poyarekar
The current scheme to identify which module a translation unit is built in depends on defining multiple macros IS_IN_* and also defining NOT_IN_libc if we're building a non-libc module. In addition, there is an IN_LIB macro that does effectively the same thing, but for different modules (notably the systemtap probes). This macro scheme unifies both ideas to use just one macro IN_MODULE and assign it a value depending on the module it is being built into. If the module is not defined, it defaults to MODULE_libc. Patches that follow will replace uses of IS_IN_* variables with the IS_IN() macro. libc-symbols.h has been converted already to give an example of how such a transition will look. Verified that there are no relevant binary changes. One source change that will crop up repeatedly is that of nscd_stat, since it uses the build timestamp as a constant in its logic. * Makeconfig (in-module): Get value of libof set for the translation unit. (CPPFLAGS): Use $(in-module). * Makerules: Don't suffix routine names for nonlib. * include/libc-modules.h: New file. * include/libc-symbols.h: Include libc-modules.h (IS_IN): New macro to replace IS_IN_* macros. * elf/Makefile: Set libof-* for each routine. * elf/rtld-Rules: Likewise. * extra-modules.mk: Likewise. * iconv/Makefile: Likewise. * iconvdata/Makefile: Likewise. * locale/Makefile: Likewise. * malloc/Makefile: Likewise. * nss/Makefile: Likewise. * sysdeps/gnu/Makefile: Likewise. * sysdeps/ieee754/ldbl-opt/Makefile: Likewise. * sysdeps/unix/sysv/linux/Makefile: Likewise. * sysdeps/s390/s390-64/Makefile: Likewise. * nscd/Makefile: Set libof-* for each routine. Set CFLAGS and CPPFLAGS for nscd instead of nonlib.
2014-11-06Run check-localpltk/textrel/execstack over ld.so.Carlos O'Donell
For maximum paranoia we run ld.so through the normal set of tests for all of the shared libraries. This includes running ld.so through check-localplt, check-textrel, and check-execstack. While none of these should trigger any failures given the way ld.so is built, it might possibly fail if a developer does something wrong. This paranoia was triggered by a discussion over the use of __strcpy vs. strcpy [1] and if the symbol could leak and use the libc.so version. The check-localplt test fails right away because localplt.data needs updating for all arches. By default we add 6 new symbols: __tls_get_addr, __libc_memalign, malloc, calloc, realloc and free. Other machines like i386, power, and s390 require some different symbol sets e.g. ___tls_get_addr vs. __tls_get_addr for i386.
