2018-12-21Update longlong.h.Joseph Myers
This patch updates longlong.h from GCC. There were no local changes in glibc (the previous version was identical to the r232143 GCC version, apart from copyright dates which had been updated in both places), so this patch makes it identical to the version in GCC again. Tested for x86_64 and x86. Also tested with build-many-glibcs.py for its RISC-V configurations, as the glibc architecture with the most substantial changes in longlong.h in this patch. * stdlib/longlong.h: Update from GCC.
2018-12-05Add __v*printf_internal with flags argumentsZack Weinberg
There are a lot more printf variants than there are scanf variants, and the code for setting up and tearing down their custom FILE variants around the call to __vf(w)printf is more complicated and variable. Therefore, I have added _internal versions of all the v*printf variants, rather than introducing helper routines so that they can all directly call __vf(w)printf_internal, as was done with scanf. As with the scanf changes, in this patch the _internal functions still look at the environmental mode bits and all callers pass 0 for the flags parameter. Several of the affected public functions had _IO_ name aliases that were not exported (but, in one case, appeared in libio.h anyway); I was originally planning to leave them as aliases to avoid having to touch internal callers, but it turns out ldbl_*_alias only work for exported symbols, so they've all been removed instead. It also turns out there were hardly any internal callers. _IO_vsprintf and _IO_vfprintf *are* exported, so those two stick around. Summary for the changes to each of the affected symbols: _IO_vfprintf, _IO_vsprintf: All internal calls removed, thus the internal declarations, as well as uses of libc_hidden_proto and libc_hidden_def, were also removed. The external symbol is now exposed via uses of ldbl_strong_alias to __vfprintf_internal and __vsprintf_internal, respectively. _IO_vasprintf, _IO_vdprintf, _IO_vsnprintf, _IO_vfwprintf, _IO_vswprintf, _IO_obstack_vprintf, _IO_obstack_printf: All internal calls removed, thus declaration in internal headers were also removed. They were never exported, so there are no aliases tying them to the internal functions. I.e.: entirely gone. __vsnprintf: Internal calls were always preceded by macros such as #define __vsnprintf _IO_vsnprintf, and #define __vsnprintf vsnprintf The macros were removed and their uses replaced with calls to the new internal function __vsnprintf_internal. Since there were no internal calls, the internal declaration was also removed. The external symbol is preserved with ldbl_weak_alias to ___vsnprintf. __vfwprintf: All internal calls converted into calls to __vfwprintf_internal, thus the internal declaration was removed. The function is now a wrapper that calls __vfwprintf_internal. The external symbol is preserved. __vswprintf: Similarly, but no external symbol. __vasprintf, __vdprintf, __vfprintf, __vsprintf: New internal wrappers. Not exported. vasprintf, vdprintf, vfprintf, vsprintf, vsnprintf, vfwprintf, vswprintf, obstack_vprintf, obstack_printf: These functions used to be aliases to the respective _IO_* function, they are now aliases to their respective __* functions. Tested for powerpc and powerpc64le.
2018-11-30stdlib: assert on NULL function pointer in atexit etc. [BZ #20544]Paul Pluzhnikov
2018-11-16Use STRFMON_LDBL_IS_DBL instead of __ldbl_is_dbl.Zack Weinberg
On platforms where long double used to have the same format as double, but later switched to a different format (alpha, s390, sparc, and powerpc), accessing the older behavior is possible and it happens via __nldbl_* functions (not on the API, but accessible from header redirection and from compat symbols). These functions write to the global flag __ldbl_is_dbl, which tells other functions that long double variables should be handled as double. This patch takes the first step towards removing this global flag and creates __vstrfmon_l_internal, which takes an explicit flags parameter. This change arguably makes the generated code slightly worse on architectures where __ldbl_is_dbl is never true; right now, on those architectures, it's a compile-time constant; after this change, the compiler could theoretically prove that __vstrfmon_l_internal was never called with a nonzero flags argument, but it would probably need LTO to do it. This is not performance critical code and I tend to think that the maintainability benefits of removing action at a distance are worth it. However, we _could_ wrap the runtime flag check with a macro that was defined to ignore its argument and always return false on architectures where __ldbl_is_dbl is never true, if people think the codegen benefits are important. Tested for powerpc and powerpc64le.

2018-10-30stdlib/test-bz22786: Avoid spurious test failures using alias mappingsFlorian Weimer
On systems without enough random-access memory, stdlib/test-bz22786 will go deeply into swap and time out, even with a substantial TIMEOUTFACTOR. This commit adds a facility to construct repeating strings with alias mappings, so that the requirement for physical memory, and uses it in stdlib/test-bz22786.
2018-10-24Y2038: Add 64-bit time for all architecturesAlbert ARIBAUD (3ADEV)
glibc support for 64-bit time_t on 32-bit architectures will involve: - Using 64-bit times inside glibc, with conversions to and from 32-bit times taking place as necessary for interfaces using such times. - Adding 64-bit-time support in the glibc public API. This support should be dynamic, i.e. glibc should provide both 32-bit and 64-bit implementations and let user code choose at compile time whether to use the 32-bit or 64-bit interfaces. This requires a glibc-internal name for a type for times that are always 64-bit. Based on __TIMESIZE, a new macro is defined, __TIME64_T_TYPE, which is always the right __*_T_TYPE to hold a 64-bit-time. __TIME64_T_TYPE equals __TIME_T_TYPE if __TIMESIZE equals 64 and equals __SQUAD_T_TYPE otherwise. __time64_t can then replace uses of internal_time_t. This patch was tested by running 'make check' on branch master then applying this patch and its predecessor and running 'make check' again, and checking that both 'make check' yield identical results. This was done on x86_64-linux-gnu and i686-linux-gnu. * bits/time64.h: New file. * include/time.h: Replace internal_time_t with __time64_t. * posix/bits/types (__time64_t): Add. * stdlib/Makefile: Add bits/time64.h to includes. * time/tzfile.c: Replace internal_time_t with __time64_t.
2018-10-24 Y2038: provide size of default time_t for target architectureAlbert ARIBAUD (3ADEV)
To determine whether the default time_t interfaces are 32-bit and so need conversions, or are 64-bit and so are compatible with the internal 64-bit type without conversions, a macro giving the size of the default time_t is also required. This macro is called __TIMESIZE. This macro can then be used instead of __WORDSIZE in msq-pad.h and shm-pad.h files, which in turn allows removing their x86 variants, and in sem-pad.h files but keeping the x86 variant. This patch was tested by running 'make check' on branch master then applying this patch and running 'make check' again, and checking that both 'make check' yield identical results. This was done on x86_64-linux-gnu and i686-linux-gnu. * bits/timesize.h: New file. * stdlib/Makefile (headers): Add bits/timesize.h. * sysdeps/unix/sysv/linux/bits/msq-pad.h (__MSQ_PAD_AFTER_TIME): Use __TIMESIZE instead of __WORDSIZE. * sysdeps/unix/sysv/linux/bits/sem-pad.h (__SEM_PAD_AFTER_TIME): Likewise. * sysdeps/unix/sysv/linux/bits/shm-pad.h (__SHM_PAD_AFTER_TIME): Likewise. * sysdeps/unix/sysv/linux/hppa/bits/msq-pad.h (__MSQ_PAD_BEFORE_TIME): Likewise. * sysdeps/unix/sysv/linux/hppa/bits/sem-pad.h (__SEM_PAD_BEFORE_TIME): Likewise. * sysdeps/unix/sysv/linux/hppa/bits/shm-pad.h (__SHM_PAD_BEFORE_TIME, __SHM_PAD_BETWEEN_TIME_AND_SEGSZ): Likewise. * sysdeps/unix/sysv/linux/mips/bits/msq-pad.h (__MSQ_PAD_AFTER_TIME, __MSQ_PAD_BEFORE_TIME): Likewise. * sysdeps/unix/sysv/linux/powerpc/bits/msq-pad.h (__MSQ_PAD_BEFORE_TIME): Likewise. * sysdeps/unix/sysv/linux/powerpc/bits/sem-pad.h (__SEM_PAD_BEFORE_TIME): Likewise. * sysdeps/unix/sysv/linux/powerpc/bits/shm-pad.h (__SHM_PAD_BEFORE_TIME, __SHM_PAD_BETWEEN_TIME_AND_SEGSZ): Likewise. * sysdeps/unix/sysv/linux/sparc/bits/msq-pad.h (__MSQ_PAD_BEFORE_TIME): Likewise. * sysdeps/unix/sysv/linux/sparc/bits/sem-pad.h (__SEM_PAD_BEFORE_TIME): Likewise. * sysdeps/unix/sysv/linux/sparc/bits/shm-pad.h (__SHM_PAD_BEFORE_TIME): Likewise. * sysdeps/unix/sysv/linux/x86/bits/msq-pad.h: Delete file. * sysdeps/unix/sysv/linux/x86/bits/shm-pad.h: Likewise. * sysdeps/unix/sysv/linux/x86/bits/timesize.h: New file.

2018-09-27Fix stack overflow in tst-setcontext9 (bug 23717)Andreas Schwab
The function f1a, executed on a stack of size 32k, allocates an object of size 32k on the stack. Make the stack variables static to reduce excessive stack usage.
2018-09-19Fix tst-setcontext9 for optimized small stacks.Carlos O'Donell
If the compiler reduces the stack usage in function f1 before calling into function f2, then when we swapcontext back to f1 and continue execution we may overwrite registers that were spilled to the stack while f2 was executing. Later when we return to f2 the corrupt registers will be reloaded from the stack and the test will crash. This was most commonly observed on i686 with __x86.get_pc_thunk.dx and needing to save and restore $edx. Overall i686 has few registers and the spilling to the stack is bound to happen, therefore the solution to making this test robust is to split function f1 into two parts f1a and f1b, and allocate f1b it's own stack such that subsequent execution does not overwrite the stack in use by function f2. Tested on i686 and x86_64. Signed-off-by: Carlos O'Donell <carlos@redhat.com>
2018-08-30reallocarray: Declare under _DEFAULT_SOURCEFlorian Weimer
Initially, this function was restricted to _GNU_SOURCE, but experience shows that compatibility with existing build systems is improved if we declare it under _DEFAULT_SOURCE as well.
2018-08-30Test stdlib/test-bz22786 exits now with unsupported if malloc fails.Stefan Liebler
The test tries to allocate more than 2^31 bytes which will always fail on s390 as it has maximum 2^31bit of memory. Before commit 6c3a8a9d868a8deddf0d6dcc785b6d120de90523, this test returned unsupported if malloc fails. This patch re enables this behaviour. Furthermore support_delete_temp_files() failed to remove the temp directory in this case as it is not empty due to the created symlink. Thus the creation of the symlink is moved behind malloc.

2018-08-13mbstowcs: Remove outdated commentFlorian Weimer
ISO C requires that there is no effect on any global conversion state, so the change in commit 9f097308c7465443765d1e25699a4cf33eff5455 was correct in princple.
2018-08-10Move __fentry__ version definition to sysdeps/{i386,x86_64}Ilya Leoshkevich
__fentry__ symbol is currently not defined for other architectures. Attempts to introduce it cause abicheck to fail, because it will be available since 2.29 earliest, and not 2.13, which is the case for Intel. With the new code, abicheck passes for i686-linux-gnu, x86_64-linux-gnu and x86_64-linux-gnu32 triples. ChangeLog: * stdlib/Versions: Remove __fentry__. * sysdeps/i386/Versions: Add __fentry__. * sysdeps/x86_64/Versions: Add __fentry__.

2018-07-18Avoid insecure usage of tmpnam in tests.Joseph Myers
Various glibc testcases use tmpnam in ways subject to race conditions (generate a temporary file name, then later open that file without O_EXCL). This patch fixes those tests to use mkstemp - generally a minimal local fix to use mkstemp instead of tmpnam, rather than a larger fix to use other testsuite infrastructure for temporary files. The unchanged use of tmpnam in posix/wordexp-test.c would fail safe in the event of a race (it's generating a name for use with mkdir rather than for a file to be opened for writing).

2018-06-29Disallow use of DES encryption functions in new programs.Zack Weinberg
The functions encrypt, setkey, encrypt_r, setkey_r, cbc_crypt, ecb_crypt, and des_setparity should not be used in new programs, because they use the DES block cipher, which is unacceptably weak by modern standards. Demote all of them to compatibility symbols, and remove their prototypes from installed headers. cbc_crypt, ecb_crypt, and des_setparity were already compat symbols when glibc was configured with --disable-obsolete-rpc. POSIX requires encrypt and setkey to be available when _XOPEN_CRYPT is defined, so this change also removes the definition of X_OPEN_CRYPT from <unistd.h>. The entire "DES Encryption" section is dropped from the manual, as is the mention of AUTH_DES and FIPS 140-2 in the introduction to crypt.texi. The documentation of 'memfrob' cross-referenced the DES Encryption section, which is replaced by a hyperlink to libgcrypt, and while I was in there I spruced up the actual documentation of 'memfrob' and 'strfry' a little. It's still fairly jokey, because those functions _are_ jokes, but they do also have real use cases, so people trying to use them for real should have all the information they need. DES-based authentication for Sun RPC is also insecure and should be deprecated or even removed, but maybe that can be left as TI-RPC's problem.

2018-06-13Fix strtod overflow detection (bug 23279).Joseph Myers
As shown by bug 23279, strtod's round_and_return has an off-by-one error in its overflow detection, only counting an exponent greater than MAX_EXP as overflowing when an exponent of MAX_EXP also means overflow (recall the ISO C definition of DBL_MAX_EXP etc. is based on a floating-point model where 2^exp is multiplied by a value in the interval [0.5, 1), so 2^MAX_EXP is not representable). For decimal arguments to strtod, a separate overflow check in the main implementation covers the case where the integer part of the argument (truncated to the nearest integer towards zero) has more than MAX_EXP bits, meaning that this issue in round_and_return only affects cases (arguments with absolute value strictly between the maximum representable value and 2^MAX_EXP) where overflow depends on the rounding mode; in such cases, the returned value would still have been correct on overflow but without the overflow exception being raised or errno being set to ERANGE. For hex float arguments, however, other cases can arise, as shown in bug 23279, where a value with exponent already set to MAX_EXP is passed into round_and_return and a result can wrongly end up being NaN, or infinity instead of the largest finite value. This patch fixes the off-by-one error, adds testing of overflow exceptions to the tst-strtod-round framework, and adds tests of these issues. Tested for x86_64. Also ran the tst-strtod-round tests for powerpc to make sure the new tests didn't introduce any new failures for IBM long double.

2018-05-11Do not include math-barriers.h in math_private.h.Joseph Myers
This patch continues the math_private.h cleanup by stopping math_private.h from including math-barriers.h and making the users of the barrier macros include the latter header directly. No attempt is made to remove any math_private.h includes that are now unused, except in strtod_l.c where that is done to avoid line number changes in assertions, so that installed stripped shared libraries can be compared before and after the patch. (I think the floating-point environment support in math_private.h should also move out - some architectures already have fenv_private.h as an architecture-internal header included from their math_private.h - and after moving that out might be a better time to identify unused math_private.h includes.)

2018-05-09Move math_narrow_eval to separate math-narrow-eval.h.Joseph Myers
This patch continues cleaning up the math_private.h header, which contains lots of different definitions many of which are only needed by a limited subset of files using that header (and some of which are overridden by architectures that only want to override selected parts of the header), by moving the math_narrow_eval macro out to a separate math-narrow-eval.h header, only included by those files that need it. That header is placed in include/ (since it's used in stdlib/, not just files built in math/, but no sysdeps variants are needed at present). Tested for x86_64, and with build-many-glibcs.py. (Installed stripped shared libraries change because of line numbers in assertions in strtod_l.c.) * include/math-narrow-eval.h: New file.

2018-03-20Fix signed integer overflow in random_r (bug 17343).Joseph Myers
Bug 17343 reports that stdlib/random_r.c has code with undefined behavior because of signed integer overflow on int32_t. This patch changes the code so that the possibly overflowing computations use unsigned arithmetic instead. Note that the bug report refers to "Most code" in that file. The places changed in this patch are the only ones I found where I think such overflow can occur. Tested for x86_64 and x86.

2017-12-15Fix testing with read-only source directory.Joseph Myers
Three tests fail with a read-only source directory because they try to write into the source directory. None of these write into it in a way that should actually be problematic for concurrent builds sharing the same writable source directory, but avoiding any writing into the source directory (from testing, or from building glibc if the source timestamps are properly ordered) is still a good idea, as being able to build with read-only sources helps make sure there isn't anything that could cause problems for concurrent builds. This patch changes the tests in question to use either /tmp or the build directory to write their temporary files (or to test O_TMPFILE, as applicable). Tested for x86_64. * io/Makefile (tst-open-tmpfile-ARGS): New variable. * posix/tst-mmap-offset.c (fname): Use /tmp. * stdlib/tst-setcontext3.sh (tempfile): Use ${objpfx}.

2017-12-07Add _Float32 function aliases.Joseph Myers
This patch concludes filling out TS 18661-3 support for different types by adding *f32 function aliases of float functions to support _Float32. As with _Float64 and _Float32x, this is supported for all glibc configurations. As with the previous such patches there are some x86 ulps updates because of inline functions present for float but not for _Float32. The patch also has the usual bits/floatn-common.h update, symbol versions, ABI baselines updates, test enablement and documentation. Tested for x86_64 and x86, and with build-many-glibcs.py, with both GCC 6 and GCC 7. * bits/floatn-common.h (__HAVE_FLOAT32): Define to 1. * manual/math.texi (Mathematics): Document support for _Float32. * math/Makefile (test-types): Add float32. * math/Versions (GLIBC_2.27): Add _Float32 functions. * stdlib/Versions (GLIBC_2.27): Likewise. * wcsmbs/Versions (GLIBC_2.27): Likewise. * sysdeps/unix/sysv/linux/aarch64/libc.abilist: Update. * sysdeps/unix/sysv/linux/aarch64/libm.abilist: Likewise. * sysdeps/unix/sysv/linux/alpha/libc.abilist: Likewise. * sysdeps/unix/sysv/linux/alpha/libm.abilist: Likewise. * sysdeps/unix/sysv/linux/arm/libc.abilist: Likewise. * sysdeps/unix/sysv/linux/arm/libm.abilist: Likewise. * sysdeps/unix/sysv/linux/hppa/libc.abilist: Likewise. * sysdeps/unix/sysv/linux/hppa/libm.abilist: Likewise. * sysdeps/unix/sysv/linux/i386/libc.abilist: Likewise. * sysdeps/unix/sysv/linux/i386/libm.abilist: Likewise. * sysdeps/unix/sysv/linux/ia64/libc.abilist: Likewise. * sysdeps/unix/sysv/linux/ia64/libm.abilist: Likewise. * sysdeps/unix/sysv/linux/m68k/coldfire/libc.abilist: Likewise. * sysdeps/unix/sysv/linux/m68k/coldfire/libm.abilist: Likewise. * sysdeps/unix/sysv/linux/m68k/m680x0/libc.abilist: Likewise. * sysdeps/unix/sysv/linux/m68k/m680x0/libm.abilist: Likewise. * sysdeps/unix/sysv/linux/microblaze/libc.abilist: Likewise. * sysdeps/unix/sysv/linux/microblaze/libm.abilist: Likewise. * sysdeps/unix/sysv/linux/mips/mips32/fpu/libc.abilist: Likewise. * sysdeps/unix/sysv/linux/mips/mips32/libm.abilist: Likewise. * sysdeps/unix/sysv/linux/mips/mips32/nofpu/libc.abilist: Likewise. * sysdeps/unix/sysv/linux/mips/mips64/libm.abilist: Likewise. * sysdeps/unix/sysv/linux/mips/mips64/n32/libc.abilist: Likewise. * sysdeps/unix/sysv/linux/mips/mips64/n64/libc.abilist: Likewise. * sysdeps/unix/sysv/linux/nios2/libc.abilist: Likewise. * sysdeps/unix/sysv/linux/nios2/libm.abilist: Likewise. * sysdeps/unix/sysv/linux/powerpc/powerpc32/fpu/libc.abilist: Likewise. * sysdeps/unix/sysv/linux/powerpc/powerpc32/fpu/libm.abilist: Likewise. * sysdeps/unix/sysv/linux/powerpc/powerpc32/nofpu/libc.abilist: Likewise. * sysdeps/unix/sysv/linux/powerpc/powerpc32/nofpu/libm.abilist: Likewise. * sysdeps/unix/sysv/linux/powerpc/powerpc64/libc-le.abilist: Likewise. * sysdeps/unix/sysv/linux/powerpc/powerpc64/libc.abilist: Likewise. * sysdeps/unix/sysv/linux/powerpc/powerpc64/libm-le.abilist: Likewise. * sysdeps/unix/sysv/linux/powerpc/powerpc64/libm.abilist: Likewise. * sysdeps/unix/sysv/linux/s390/s390-32/libc.abilist: Likewise. * sysdeps/unix/sysv/linux/s390/s390-32/libm.abilist: Likewise. * sysdeps/unix/sysv/linux/s390/s390-64/libc.abilist: Likewise. * sysdeps/unix/sysv/linux/s390/s390-64/libm.abilist: Likewise. * sysdeps/unix/sysv/linux/sh/libc.abilist: Likewise. * sysdeps/unix/sysv/linux/sh/libm.abilist: Likewise. * sysdeps/unix/sysv/linux/sparc/sparc32/libc.abilist: Likewise. * sysdeps/unix/sysv/linux/sparc/sparc32/libm.abilist: Likewise. * sysdeps/unix/sysv/linux/sparc/sparc64/libc.abilist: Likewise. * sysdeps/unix/sysv/linux/sparc/sparc64/libm.abilist: Likewise. * sysdeps/unix/sysv/linux/tile/tilegx/tilegx32/libc.abilist: Likewise. * sysdeps/unix/sysv/linux/tile/tilegx/tilegx32/libm.abilist: Likewise. * sysdeps/unix/sysv/linux/tile/tilegx/tilegx64/libc.abilist: Likewise. * sysdeps/unix/sysv/linux/tile/tilegx/tilegx64/libm.abilist: Likewise. * sysdeps/unix/sysv/linux/tile/tilepro/libc.abilist: Likewise. * sysdeps/unix/sysv/linux/tile/tilepro/libm.abilist: Likewise. * sysdeps/unix/sysv/linux/x86_64/64/libc.abilist: Likewise. * sysdeps/unix/sysv/linux/x86_64/64/libm.abilist: Likewise. * sysdeps/unix/sysv/linux/x86_64/x32/libc.abilist: Likewise. * sysdeps/unix/sysv/linux/x86_64/x32/libm.abilist: Likewise. * sysdeps/i386/fpu/libm-test-ulps: Likewise. * sysdeps/i386/i686/fpu/multiarch/libm-test-ulps: Likewise.
2017-12-06Support defining strtof32, wcstof32 aliases.Joseph Myers
This patch adds support for defining strtof32, wcstof32, strtof32_l and wcstof32_l functions as aliases of the corresponding float functions when _Float32 support is enabled. Tested for x86_64; also tested with build-many-glibcs.py in conjunction with other _Float32 changes. * stdlib/strtof.c: Include <bits/floatn.h> [__HAVE_FLOAT32 && !__HAVE_DISTINCT_FLOAT32] (strtof32): Define and later undefine as macro. Define as weak alias if [!USE_WIDE_CHAR]. [__HAVE_FLOAT32 && !__HAVE_DISTINCT_FLOAT32] (wcstof32): Define and later undefine as macro. Define as weak alias if [USE_WIDE_CHAR]. * stdlib/strtof_l.c: Include <bits/floatn.h> [__HAVE_FLOAT32 && !__HAVE_DISTINCT_FLOAT32] (strtof32_l): Define and later undefine as macro. Define as weak alias if [!USE_WIDE_CHAR]. [__HAVE_FLOAT32 && !__HAVE_DISTINCT_FLOAT32] (wcstof32_l): Define and later undefine as macro. Define as weak alias if [USE_WIDE_CHAR].
