* elf: Introduce <dl-call_tls_init_tp.h> and call_tls_init_tp (bug 29249)Florian Weimer2022-11-031-2/+1
| | | | | | | | This makes it more likely that the compiler can compute the strlen argument in _startup_fatal at compile time, which is required to avoid a dependency on strlen this early during process startup. Reviewed-by: Szabolcs Nagy <szabolcs.nagy@arm.com>
* Use PTR_MANGLE and PTR_DEMANGLE unconditionally in C sourcesFlorian Weimer2022-10-181-2/+0
| | | | | | | | | | | | | | | | | In the future, this will result in a compilation failure if the macros are unexpectedly undefined (due to header inclusion ordering or header inclusion missing altogether). Assembler sources are more difficult to convert. In many cases, they are hand-optimized for the mangling and no-mangling variants, which is why they are not converted. sysdeps/s390/s390-32/__longjmp.c and sysdeps/s390/s390-64/__longjmp.c are special: These are C sources, but most of the implementation is in assembler, so the PTR_DEMANGLE macro has to be undefined in some cases, to match the assembler style.

* Introduce <pointer_guard.h>, extracted from <sysdep.h>Florian Weimer2022-10-183-0/+3
| | | | | | | | | | | | | | This allows us to define a generic no-op version of PTR_MANGLE and PTR_DEMANGLE. In the future, we can use PTR_MANGLE and PTR_DEMANGLE unconditionally in C sources, avoiding an unintended loss of hardening due to missing include files or unlucky header inclusion ordering. In i386 and x86_64, we can avoid a <tls.h> dependency in the C code by using the computed constant from <tcb-offsets.h>. <sysdep.h> no longer includes these definitions, so there is no cyclic dependency anymore when computing the <tcb-offsets.h> constants.

* C-SKY: Use an autoconf template to produce `preconfigure'Maciej W. Rozycki2022-05-132-10/+72
| | | | | | | | | | | | Avoid fiddling with autoconf internals and use AC_DEFINE_UNQUOTED to define macros in the configuration headers rather than handcoding an equivalent shell sequence with the use of the `as_echo' undocumented variable. Switch to using AC_MSG_ERROR rather than `echo' and `exit' directly for error handling. Owing to the lack of any kind of error annotation it makes it difficult to spot the message in the flood in a parallel build and neither it is logged in `config.log'.
* elf: Replace PI_STATIC_AND_HIDDEN with opposite HIDDEN_VAR_NEEDS_DYNAMIC_RELOCFangrui Song2022-04-262-5/+0
| | | | | | | | | | | | | | | | | | PI_STATIC_AND_HIDDEN indicates whether accesses to internal linkage variables and hidden visibility variables in a shared object (ld.so) need dynamic relocations (usually R_*_RELATIVE). PI (position independent) in the macro name is a misnomer: a code sequence using GOT is typically position-independent as well, but using dynamic relocations does not meet the requirement. Not defining PI_STATIC_AND_HIDDEN is legacy and we expect that all new ports will define PI_STATIC_AND_HIDDEN. Current ports defining PI_STATIC_AND_HIDDEN are more than the opposite. Change the configure default. No functional change. Reviewed-by: Adhemerval Zanella <adhemerval.zanella@linaro.org>

Also add a new configuration option --disable-default-pie to prevent building programs as PIE. Only the following architectures now have PIE disabled by default because they do not work at the moment. hppa, ia64, alpha and csky don't work because the linker is unable to handle a pcrel relocation generated from PIE objects. The microblaze compiler is currently failing with an ICE. GNU hurd tries to enable static-pie, which does not work and hence fails. All these targets have default PIE disabled at the moment and I have left it to the target maintainers to enable PIE on their targets. build-many-glibcs runs clean for all targets. I also tested x86_64 on Fedora and Ubuntu, to verify that the default build as well as --disable-default-pie work as expected with both system toolchains.

* Remove TLS_TCB_ALIGN and TLS_INIT_TCB_ALIGNFlorian Weimer2021-12-091-6/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | TLS_INIT_TCB_ALIGN is not actually used. TLS_TCB_ALIGN was likely introduced to support a configuration where the thread pointer has not the same alignment as THREAD_SELF. Only ia64 seems to use that, but for the stack/pointer guard, not for storing tcbhead_t. Some ports use TLS_TCB_OFFSET and TLS_PRE_TCB_SIZE to shift the thread pointer, potentially landing in a different residue class modulo the alignment, but the changes should not impact that. In general, given that TLS variables have their own alignment requirements, having different alignment for the (unshifted) thread pointer and struct pthread would potentially result in dynamic offsets, leading to more complexity. hppa had different values before: __alignof__ (tcbhead_t), which seems to be 4, and __alignof__ (struct pthread), which was 8 (old default) and is now 32. However, it defines THREAD_SELF as: /* Return the thread descriptor for the current thread. */ # define THREAD_SELF \ ({ struct pthread *__self; \ __self = __get_cr27(); \ __self - 1; \ }) So the thread pointer points after struct pthread (hence __self - 1), and they have to have the same alignment on hppa as well. Similarly, on ia64, the definitions were different. We have: # define TLS_PRE_TCB_SIZE \ (sizeof (struct pthread) \ + (PTHREAD_STRUCT_END_PADDING < 2 * sizeof (uintptr_t) \ ? ((2 * sizeof (uintptr_t) + __alignof__ (struct pthread) - 1) \ & ~(__alignof__ (struct pthread) - 1)) \ : 0)) # define THREAD_SELF \ ((struct pthread *) ((char *) __thread_self - TLS_PRE_TCB_SIZE)) And TLS_PRE_TCB_SIZE is a multiple of the struct pthread alignment (confirmed by the new _Static_assert in sysdeps/ia64/libc-tls.c). On m68k, we have a larger gap between tcbhead_t and struct pthread. But as far as I can tell, the port is fine with that. The definition of TCB_OFFSET is sufficient to handle the shifted TCB scenario. This fixes commit 23c77f60181eb549f11ec2f913b4270af29eee38 ("nptl: Increase default TCB alignment to 32").

* String: Add support for __memcmpeq() ABI on all targetsNoah Goldstein2021-10-261-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | No bug. This commit adds support for __memcmpeq() as a new ABI for all targets. In this commit __memcmpeq() is implemented only as an alias to the corresponding targets memcmp() implementation. __memcmpeq() is added as a new symbol starting with GLIBC_2.35 and defined in string.h with comments explaining its behavior. Basic tests that it is callable and works where added in string/tester.c As discussed in the proposal "Add new ABI '__memcmpeq()' to libc" __memcmpeq() is essentially a reserved namespace for bcmp(). The means is shares the same specifications as memcmp() except the return value for non-equal byte sequences is any non-zero value. This is less strict than memcmp()'s return value specification and can be better optimized when a boolean return is all that is needed. __memcmpeq() is meant to only be called by compilers if they can prove that the return value of a memcmp() call is only used for its boolean value. All tests in string/tester.c passed. As well build succeeds on x86_64-linux-gnu target.
* elf: Fix dynamic-link.h usage on rtld.cAdhemerval Zanella2021-10-141-4/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The 4af6982e4c fix does not fully handle RTLD_BOOTSTRAP usage on rtld.c due two issues: 1. RTLD_BOOTSTRAP is also used on dl-machine.h on various architectures and it changes the semantics of various machine relocation functions. 2. The elf_get_dynamic_info() change was done sideways, previously to 490e6c62aa get-dynamic-info.h was included by the first dynamic-link.h include *without* RTLD_BOOTSTRAP being defined. It means that the code within elf_get_dynamic_info() that uses RTLD_BOOTSTRAP is in fact unused. To fix 1. this patch now includes dynamic-link.h only once with RTLD_BOOTSTRAP defined. The ELF_DYNAMIC_RELOCATE call will now have the relocation fnctions with the expected semantics for the loader. And to fix 2. part of 4af6982e4c is reverted (the check argument elf_get_dynamic_info() is not required) and the RTLD_BOOTSTRAP pieces are removed. To reorganize the includes the static TLS definition is moved to its own header to avoid a circular dependency (it is defined on dynamic-link.h and dl-machine.h requires it at same time other dynamic-link.h definition requires dl-machine.h defitions). Also ELF_MACHINE_NO_REL, ELF_MACHINE_NO_RELA, and ELF_MACHINE_PLT_REL are moved to its own header. Only ancient ABIs need special values (arm, i386, and mips), so a generic one is used as default. The powerpc Elf64_FuncDesc is also moved to its own header, since csu code required its definition (which would require either include elf/ folder or add a full path with elf/).

* elf: Avoid nested functions in the loader [BZ #27220]Fangrui Song2021-10-071-8/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | dynamic-link.h is included more than once in some elf/ files (rtld.c, dl-conflict.c, dl-reloc.c, dl-reloc-static-pie.c) and uses GCC nested functions. This harms readability and the nested functions usage is the biggest obstacle prevents Clang build (Clang doesn't support GCC nested functions). The key idea for unnesting is to add extra parameters (struct link_map *and struct r_scope_elm *[]) to RESOLVE_MAP, ELF_MACHINE_BEFORE_RTLD_RELOC, ELF_DYNAMIC_RELOCATE, elf_machine_rel[a], elf_machine_lazy_rel, and elf_machine_runtime_setup. (This is inspired by Stan Shebs' ppc64/x86-64 implementation in the google/grte/v5-2.27/master which uses mixed extra parameters and static variables.) Future simplification: * If mips elf_machine_runtime_setup no longer needs RESOLVE_GOTSYM, elf_machine_runtime_setup can drop the `scope` parameter. * If TLSDESC no longer need to be in elf_machine_lazy_rel, elf_machine_lazy_rel can drop the `scope` parameter.

* Reduce the statically linked startup code [BZ #23323]Florian Weimer2021-02-251-13/+4
| | | | | | | | | | | | | | | | | | | It turns out the startup code in csu/elf-init.c has a perfect pair of ROP gadgets (see Marco-Gisbert and Ripoll-Ripoll, "return-to-csu: A New Method to Bypass 64-bit Linux ASLR"). These functions are not needed in dynamically-linked binaries because DT_INIT/DT_INIT_ARRAY are already processed by the dynamic linker. However, the dynamic linker skipped the main program for some reason. For maximum backwards compatibility, this is not changed, and instead, the main map is consulted from __libc_start_main if the init function argument is a NULL pointer. For statically linked binaries, the old approach based on linker symbols is still used because there is nothing else available. A new symbol version __libc_start_main@@GLIBC_2.34 is introduced because new binaries running on an old libc would not run their ELF constructors, leading to difficult-to-debug issues.

* aarch64: enforce >=64K guard size [BZ #26691]Szabolcs Nagy2020-10-021-0/+3
| | | | | | | | | | | | | | | | | | | | | | | There are several compiler implementations that allow large stack allocations to jump over the guard page at the end of the stack and corrupt memory beyond that. See CVE-2017-1000364. Compilers can emit code to probe the stack such that the guard page cannot be skipped, but on aarch64 the probe interval is 64K by default instead of the minimum supported page size (4K). This patch enforces at least 64K guard on aarch64 unless the guard is disabled by setting its size to 0. For backward compatibility reasons the increased guard is not reported, so it is only observable by exhausting the address space or parsing /proc/self/maps on linux. On other targets the patch has no effect. If the stack probe interval is larger than a page size on a target then ARCH_MIN_GUARD_SIZE can be defined to get large enough stack guard on libc allocated stacks. The patch does not affect threads with user allocated stacks. Fixes bug 26691.

The default pthread_rwlock_t layout differs from current ports with: 1. Internal layout is the same for 32 bits and 64 bits. 2.

* nptl: Add struct_mutex.hAdhemerval Zanella2019-11-261-7/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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: Add tests for internal pthread_rwlock_t offsetsAdhemerval Zanella2019-11-261-0/+2
| | | | | | | | | | | | | This patch new build tests to check for internal fields offsets for internal pthread_rwlock_t definition. Althoug the '__data.__flags' field layout should be preserved due static initializators, the patch also adds tests for the futexes that may be used in a shared memory (although using different libc version in such scenario is not really supported).

* Split up endian.h to minimize exposure of BYTE_ORDER.Alistair Francis2019-10-013-10/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | With only two exceptions (sys/types.h and sys/param.h, both of which historically might have defined BYTE_ORDER) the public headers that include <endian.h> only want to be able to test __BYTE_ORDER against __*_ENDIAN. This patch creates a new bits/endian.h that can be included by any header that wants to be able to test __BYTE_ORDER and/or __FLOAT_WORD_ORDER against the __*_ENDIAN constants, or needs __LONG_LONG_PAIR. It only defines macros in the implementation namespace. The existing bits/endian.h (which could not be included independently of endian.h, and only defines __BYTE_ORDER and maybe __FLOAT_WORD_ORDER) is renamed to bits/endianness.h. I also took the opportunity to canonicalize the form of this header, which we are stuck with having one copy of per architecture. Since they are so short, this means git doesn’t understand that they were renamed from existing headers, sigh. endian.h itself is a nonstandard header and its only remaining use from a standard header is guarded by __USE_MISC, so I dropped the __USE_MISC conditionals from around all of the public-namespace things it defines. (This means, an application that requests strict library conformance but includes endian.h will still see the definition of BYTE_ORDER.) A few changes to specific bits/endian(ness).h variants deserve mention: - sysdeps/unix/sysv/linux/ia64/bits/endian.h is moved to sysdeps/ia64/bits/endianness.h. If I remember correctly, ia64 did have selectable endianness, but we have assembly code in sysdeps/ia64 that assumes it’s little-endian, so there is no reason to treat the ia64 endianness.h as linux-specific. - The C-SKY port does not fully support big-endian mode, the compile will error out if __CSKYBE__ is defined. - The PowerPC port had extra logic in its bits/endian.h to detect a broken compiler, which strikes me as unnecessary, so I removed it. - The only files that defined __FLOAT_WORD_ORDER always defined it to the same value as __BYTE_ORDER, so I removed those definitions. The SH bits/endian(ness).h had comments inconsistent with the actual setting of __FLOAT_WORD_ORDER, which I also removed. - I *removed* copyright boilerplate from the few bits/endian(ness).h headers that had it; these files record a single fact in a fashion dictated by an external spec, so I do not think they are copyrightable. As long as I was changing every copy of ieee754.h in the tree, I noticed that only the MIPS variant includes float.h, because it uses LDBL_MANT_DIG to decide among three different versions of ieee854_long_double. This patch makes it not include float.h when GCC’s intrinsic __LDBL_MANT_DIG__ is available. * string/endian.h: Unconditionally define LITTLE_ENDIAN, BIG_ENDIAN, PDP_ENDIAN, and BYTE_ORDER. Condition byteswapping macros only on !__ASSEMBLER__. Move the definitions of __BIG_ENDIAN, __LITTLE_ENDIAN, __PDP_ENDIAN, __FLOAT_WORD_ORDER, and __LONG_LONG_PAIR to... * string/bits/endian.h: ...this new file, which includes the renamed header bits/endianness.h for the definition of __BYTE_ORDER and possibly __FLOAT_WORD_ORDER. * string/Makefile: Install bits/endianness.h. * include/bits/endian.h: New wrapper. * bits/endian.h: Rename to bits/endianness.h.
