* Expand $(as-needed) and $(no-as-needed) throughout the build systemFlorian Weimer2019-12-036-34/+31
| | | | | | | | | Since commit a3cc4f48e94f32c9532ee36982ac00eb1e5719b0 ("Remove --as-needed configure test."), --as-needed support is no longer optional. The macros are not much shorter and do not provide documentary value, either, so this commit removes them.
* x86: Assume --enable-cet if GCC defaults to CET [BZ #25225]Florian Weimer2019-12-032-2/+30
| | | | | | | This links in CET support if GCC defaults to CET. Otherwise, __CET__ is defined, yet CET functionality is not compiled and linked into the dynamic loader, resulting in a linker failure due to undefined references to _dl_cet_check and _dl_open_check.
* ldbl-128ibm-compat: Add tests for strfroml, strtold, and wcstoldGabriel F. T. Gomes2019-12-037-0/+103
| | | | | | | | | | | | | | | | | Since the commit commit 86a0f56158bd9cbaf2d640e2e6c66539f4cbbcc1 Author: Rajalakshmi Srinivasaraghavan <raji@linux.vnet.ibm.com> Date: Thu Jun 28 13:57:50 2018 +0530 ldbl-128ibm-compat: Introduce ieee128 symbols IEEE long double versions of strfroml, strtold, and wcstold have been prepared, but not exposed (which will only happen when the full support for IEEE long double is complete). This patch adds tests for these functions in both IBM and IEEE long double mode. Reviewed-by: Paul E. Murphy <murphyp@linux.ibm.com>
* ldbl-128ibm-compat: Add tests for strfmon and strfmon_lGabriel F. T. Gomes2019-12-034-0/+67
| | | | | | | | | | This patch adds elementary tests to check that strfmon and strfmon_l correctly evaluate long double values with IBM Extended Precision and IEEE binary128 format. Tested for powerpc64le. Reviewed-by: Paul E. Murphy <murphyp@linux.ibm.com>
* ldbl-128ibm-compat: Add strfmon_l with IEEE long double formatRajalakshmi Srinivasaraghavan2019-12-036-4/+113
| | | | | | | | | | | | Similarly to what has been done for printf-like functions, more specifically to the internal implementation in __vfprintf_internal, this patch extends __vstrfmon_l_internal to deal with long double values with binary128 format (as a third format option and reusing the float128 implementation). Tested for powerpc64le, powerpc64, x86_64, and with build-many-glibcs. Reviewed-by: Paul E. Murphy <murphyp@linux.ibm.com>
* ldbl-128ibm-compat: Replace http with https in new filesGabriel F. T. Gomes2019-12-0363-63/+63
| | | | | | | Several commits to the ldbl-128ibm-compat directory added new files where the URL in the copyright notice pointed to an http, rather than to an https, address. This happened because I copied the notices before commit ID 5a82c74822d3. This trivial patch fixes this issue.
* elf: Do not run IFUNC resolvers for LD_DEBUG=unused [BZ #24214]Florian Weimer2019-12-029-10/+114
| | | | | | | | | This commit adds missing skip_ifunc checks to aarch64, arm, i386, sparc, and x86_64. A new test case ensures that IRELATIVE IFUNC resolvers do not run in various diagnostic modes of the dynamic loader. Reviewed-By: Szabolcs Nagy <szabolcs.nagy@arm.com>

* hurd: Fix ld.so __access override from libcSamuel Thibault2019-12-016-6/+10
| | | | | | ld.so symbols to be overriden by libc need to be extern to really get overriden. __access happens to have never been exposed, putting it to GLIBC_PRIVATE.

| | | | | Since a2e8aa0d9ea6 ("Block signals during the initial part of dlopen") dl_open uses sigprocmask, so we need a stub implementation.
* Update kernel version to 5.4 in tst-mman-consts.py.Joseph Myers2019-11-291-1/+1
| | | | | | | | This patch updates the kernel version in the test tst-mman-consts.py to 5.4. (There are no new constants covered by this test in 5.4 that need any other header changes.) Tested with build-many-glibcs.py.
* Update SOMAXCONN value from Linux 5.4.Joseph Myers2019-11-291-1/+1
| | | | | | | | | | | | | | | | | Linux 5.4 changes the SOMAXCONN value from 128 to 4096 (this isn't in a uapi header; various constants related to the kernel/userspace interface, including this one, are in the non-uapi linux/socket.h header). This patch increases the value in glibc. As I understand it, it is safe to use a higher value even with older kernels (the kernel will simply adjust the value passed to listen to be no more than the value supported in the kernel), and SOMAXCONN is actually only a default for a sysctl value in the kernel that can be changed at runtime. So I think updating the value in glibc is a reasonable and safe thing to do. Tested for x86_64.
* Update syscall-names.list for Linux 5.4.Joseph Myers2019-11-281-2/+2
| | | | | | | | This patch updates syscall-names.list for Linux 5.4. There are no new syscalls, so this is just a matter of updating the version number listed in the file. Tested with build-many-glibcs.py.

* Move _dl_open_check to its original place in dl_open_workerFlorian Weimer2019-11-271-6/+2
| | | | | | | | | | | | This reverts the non-test change from commit d0093c5cefb7f7a4143f ("Call _dl_open_check after relocation [BZ #24259]"), given that the underlying bug has been fixed properly in commit 61b74477fa7f63 ("Remove all loaded objects if dlopen fails, ignoring NODELETE [BZ #20839]"). Tested on x86-64-linux-gnu, with and without --enable-cet. Change-Id: I995a6cfb89f25d2b0cf5e606428c2a93eb48fc33
* Block signals during the initial part of dlopenFlorian Weimer2019-11-271-2/+26
| | | | | | | | | | | Lazy binding in a signal handler that interrupts a dlopen sees intermediate dynamic linker state. This has likely been always unsafe, but with the new pending NODELETE state, this is clearly incorrect. Other threads are excluded via the loader lock, but the current thread is not. Blocking signals until right before ELF constructors run is the safe thing to do. Change-Id: Iad079080ebe7442c13313ba11dc2797953faef35
* Remove all loaded objects if dlopen fails, ignoring NODELETE [BZ #20839]Florian Weimer2019-11-2710-38/+328
| | | | | | | | | | | | | This introduces a “pending NODELETE” state in the link map, which is flipped to the persistent NODELETE state late in dlopen, via activate_nodelete. During initial relocation, symbol binding records pending NODELETE state only. dlclose ignores pending NODELETE state. Taken together, this results that a partially completed dlopen is rolled back completely because new NODELETE mappings are unloaded. Tested on x86_64-linux-gnu and i386-linux-gnu.

* Avoid late dlopen failure due to scope, TLS slotinfo updates [BZ #25112]Florian Weimer2019-11-274-131/+258
| | | | | | | | | | | | | | | | | | | | | | | | This change splits the scope and TLS slotinfo updates in dlopen into two parts: one to resize the data structures, and one to actually apply the update. The call to add_to_global_resize in dl_open_worker is moved before the demarcation point at which no further memory allocations are allowed. _dl_add_to_slotinfo is adjusted to make the list update optional. There is some optimization possibility here because we could grow the slotinfo list of arrays in a single call, one the largest TLS modid is known. This commit does not fix the fatal meory allocation failure in _dl_update_slotinfo. Ideally, this error during dlopen should be recoverable. The update order of scopes and TLS data structures is retained, although it appears to be more correct to fully initialize TLS first, and then expose symbols in the newly loaded objects via the scope update. Tested on x86_64-linux-gnu. Change-Id: I240c58387dabda3ca1bcab48b02115175fa83d6c
* Avoid late failure in dlopen in global scope update [BZ #25112]Florian Weimer2019-11-272-49/+114
| | | | | | | | | | | | | | | | | | | | | | | | | | | The call to add_to_global in dl_open_worker happens after running ELF constructors for new objects. At this point, proper recovery from malloc failure would be quite complicated: We would have to run the ELF destructors and close all opened objects, something that we currently do not do. Instead, this change splits add_to_global into two phases, add_to_global_resize (which can raise an exception, called before ELF constructors run), and add_to_global_update (which cannot, called after ELF constructors). A complication arises due to recursive dlopen: After the inner dlopen consumes some space, the pre-allocation in the outer dlopen may no longer be sufficient. A new member in the namespace structure, _ns_global_scope_pending_adds keeps track of the maximum number of objects that need to be added to the global scope. This enables the inner add_to_global_resize call to take into account the needs of an outer dlopen. Most code in the dynamic linker assumes that the number of global scope entries fits into an unsigned int (matching the r_nlist member of struct r_scop_elem). Therefore, change the type of _ns_global_scope_alloc to unsigned int (from size_t), and add overflow checks. Change-Id: Ie08e2f318510d5a6a4bcb1c315f46791b5b77524
* Lazy binding failures during dlopen/dlclose must be fatal [BZ #24304]Florian Weimer2019-11-277-21/+216
| | | | | | | | | | | | | | | | | | | | | If a lazy binding failure happens during the execution of an ELF constructor or destructor, the dynamic loader catches the error and reports it using the dlerror mechanism. This is undesirable because there could be other constructors and destructors that need processing (which are skipped), and the process is in an inconsistent state at this point. Therefore, we have to issue a fatal dynamic loader error error and terminate the process. Note that the _dl_catch_exception in _dl_open is just an inner catch, to roll back some state locally. If called from dlopen, there is still an outer catch, which is why calling _dl_init via call_dl_init and a no-exception is required and cannot be avoiding by moving the _dl_init call directly into _dl_open. _dl_fini does not need changes because it does not install an error handler, so errors are already fatal there.

* resolv: Implement trust-ad option for /etc/resolv.conf [BZ #20358]Florian Weimer2019-11-2711-1/+253
| | | | | | | | | | | | | | | | | This introduces a concept of trusted name servers, for which the AD bit is passed through to applications. For untrusted name servers (the default), the AD bit in responses are cleared, to provide a safe default. This approach is very similar to the one suggested by Pavel Šimerda in <https://bugzilla.redhat.com/show_bug.cgi?id=1164339#c15>. The DNS test framework in support/ is enhanced with support for setting the AD bit in responses. Tested on x86_64-linux-gnu. Change-Id: Ibfe0f7c73ea221c35979842c5c3b6ed486495ccc
* dlsym: Do not determine caller link map if not neededFlorian Weimer2019-11-271-4/+21
| | | | | | | | | | | | | | | | Obtaining the link map is potentially very slow because it requires iterating over all loaded objects in the current implementation. If the caller supplied an explicit handle (i.e., not one of the RTLD_* constants), the dlsym implementation does not need the identity of the caller (except in the special case of auditing), so this change avoids computing it in that case. Even in the minimal case (dlsym called from a main program linked with -dl), this shows a small speedup, perhaps around five percent. The performance improvement can be arbitrarily large in principle (if _dl_find_dso_for_object has to iterate over many link maps). Change-Id: Ide5d9e2cc7ac25a0ffae8fb4c26def0c898efa29
* libio: Disable vtable validation for pre-2.1 interposed handles [BZ #25203]Florian Weimer2019-11-271-0/+5

* ldbl-128ibm-compat: Add syslog functionsGabriel F. T. Gomes2019-11-2710-1/+163
| | | | | | | | | | | | | | | | Similarly to __vfprintf_internal and __vfscanf_internal, the internal implementation of syslog functions (__vsyslog_internal) takes a 'mode_flags' parameter used to select the format of long double parameters.

| | | | | | | | | | | | | | | | | This patch removes the arch-specific atomic instruction, relying on compiler builtins. The __sparc32_atomic_locks support is removed and a configure check is added to check if compiler uses libatomic to implement CAS.

* S390: Fix handling of needles crossing a page in strstr z15 ifunc-variant. ↵Stefan Liebler2019-11-272-7/+36
| | | | | | | | | | | | | | | | | [BZ #25226] If the specified needle crosses a page-boundary, the s390-z15 ifunc variant of strstr truncates the needle which results in invalid results. This is fixed by loading the needle beyond the page boundary to v18 instead of v16. The bug is sometimes observable in test-strstr.c in check1 and check2 as the haystack and needle is stored on stack. Thus the needle can be on a page boundary. check2 is now extended to test haystack / needles located on stack, at end of page and on two pages. This bug was introduced with commit 6f47401bd5fc71209219779a0426170a9a7395b0 ("S390: Add arch13 strstr ifunc variant.") and is already released in glibc 2.30.

* Compile elf/rtld.c with -fno-tree-loop-distribute-patterns.Sandra Loosemore2019-11-261-0/+6
| | | | | | | | | | | | | | In GCC 10, the default at -O2 is now -ftree-loop-distribute-patterns. This optimization causes GCC to "helpfully" convert the hand-written loop in _dl_start into a call to memset, which is not available that early in program startup. Similar problems in other places in GLIBC have been addressed by explicitly building with -fno-tree-loop-distribute-patterns, but this one may have been overlooked previously because it only affects targets where HAVE_BUILTIN_MEMSET is not defined. This patch fixes a bug observed on nios2-linux-gnu target that caused all programs to segv on startup.

* nptl: Add struct_rwlock.hAdhemerval Zanella2019-11-2631-434/+625
| | | | | | | | | | | | | | | | | | | | | | | | This patch adds a new generic __pthread_rwlock_arch_t definition meant to be used by new ports. Its layout mimics the current usage on some 64 bits ports and it allows some ports to use the generic definition. The arch __pthread_rwlock_arch_t definition is moved from pthreadtypes-arch.h to another arch-specific header (struct_rwlock.h). Also the static intialization macro for pthread_rwlock_t is set to use an arch defined on (__PTHREAD_RWLOCK_INITIALIZER) which simplifies its implementation. The default pthread_rwlock_t layout differs from current ports with: 1. Internal layout is the same for 32 bits and 64 bits. 2. Internal flag is an unsigned short so it should not required additional padding to align for word boundary (if it is the case for the ABI). Checked with a build on affected abis.

* nptl: Add struct_mutex.hAdhemerval Zanella2019-11-2626-261/+417
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The current way of defining the common mutex definition for POSIX and C11 on pthreadtypes-arch.h (added by commit 06be6368da16104be5) is not really the best options for newer ports. It requires define some misleading flags that should be always defined as 0 (__PTHREAD_COMPAT_PADDING_MID and __PTHREAD_COMPAT_PADDING_END), it exposes options used solely for linuxthreads compat mode (__PTHREAD_MUTEX_USE_UNION and __PTHREAD_MUTEX_NUSERS_AFTER_KIND), and requires newer ports to explicit define them (adding more boilerplate code). This patch adds a new default __pthread_mutex_s definition meant to be used by newer ports. Its layout mimics the current usage on both 32 and 64 bits ports and it allows most ports to use the generic definition. Only ports that use some arch-specific definition (such as hardware lock-elision or linuxthreads compat) requires specific headers. For 32 bit, the generic definitions mimic the other 32-bit ports of using an union to define the fields uses on adaptive and robust mutexes (thus not allowing both usage at same time) and by using a single linked-list for robust mutexes. Both decisions seemed to follow what recent ports have done and make the resulting pthread_mutex_t/mtx_t object smaller. Also the static intialization macro for pthread_mutex_t is set to use a macro __PTHREAD_MUTEX_INITIALIZER where the architecture can redefine in its struct_mutex.h if it requires additional fields to be initialized.

* nptl: Cleanup mutex internal offset testsAdhemerval Zanella2019-11-2619-94/+6
| | | | | | | | | | | | | The offsets of pthread_mutex_t __data.__nusers, __data.__spins, __data.elision, __data.list are not required to be constant over the releases. Only the __data.__kind is used for static initializers. This patch also adds an additional size check for __data.__kind. Checked with a build against affected ABIs.

* ru_UA locale: use copy "ru_RU" in LC_TIME (bug 25044)Rafał Lużyński2019-11-261-69/+1
| | | | | | | | | | Replacing incorrect abbreviated weekday names "Пнд", "Вто", "Срд"... with correct ones "Пн", "Вт", "Ср"... makes the LC_TIME sections in those two locales almost identical. The only remaining difference was that ab_alt_mon elements in ru_UA were lowercase while in ru_RU they had the first letter uppercase, the latter was pointed as a better choice by a native speaker. This commit unifies LC_TIME between ru_RU and ru_UA.
