* stdlib/test-bz22786: Avoid spurious test failures using alias mappingsFlorian Weimer2018-11-021-10/+6
| | | | | | | | | | 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.

* Test stdlib/test-bz22786 exits now with unsupported if malloc fails.Stefan Liebler2018-11-021-3/+12
| | | | | | | | | | | | | | | | | | | | 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. Reviewed-by: Carlos O'Donell <carlos@redhat.com> ChangeLog: * stdlib/test-bz22786.c (do_test): Return EXIT_UNSUPPORTED if malloc fails.

* Fix stack overflow in tst-setcontext9 (bug 23717)Andreas Schwab2018-09-271-2/+2
| | | | | | | | 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. (cherry picked from commit f841c97e515a1673485a2b12b3c280073d737890)
* Fix tst-setcontext9 for optimized small stacks.Carlos O'Donell2018-09-201-9/+38
| | | | | | | | | | | | | | | | | | | 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> (cherry picked from commit 791b350dc725545e3f9b5db0f97ebdbc60c9735f)

* Avoid insecure usage of tmpnam in tests.Joseph Myers2018-07-181-4/+10
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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).

* Disallow use of DES encryption functions in new programs.Zack Weinberg2018-06-291-6/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* Fix strtod overflow detection (bug 23279).Joseph Myers2018-06-135-4391/+4845
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* Do not include math-barriers.h in math_private.h.Joseph Myers2018-05-111-1/+1

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.)

* Use libc_hidden_* for atoi (bug 15105).Joseph Myers2018-02-261-0/+1
| | | | | | | | | | | | | | Continuing the fixes for localplt test failures with -Os arising from functions not being inlined in that case, this patch fixes such failures for atoi by using libc_hidden_proto and libc_hidden_def. Tested for x86_64 (both that it removes this particular localplt failure for -Os, and that the testsuite continues to pass without -Os). [BZ #15105] * stdlib/atoi.c (atoi): Use libc_hidden_def. * include/stdlib.h [!_ISOMAC] (atoi): Use libc_hidden_proto.

* stdlib: Fixing test-*atexit*-race tests on ia64Adhemerval Zanella2018-02-011-1/+4
| | | | | | | | | | | These tests require a new thread stack size set to a value (0x20000) lower than the architecture minimum (0x30000). Set the stack size to PTHREAD_STACK_MIN in this case. Checked on ia64-linux-gnu. * stdlib/test-atexit-race-common.c (do_test): Check stack size against PTHREAD_STACK_MIN.

* Fix testing with read-only source directory.Joseph Myers2017-12-151-1/+1
| | | | | | | | | | | | | | | | | | | | | 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}.

(It so happens the set of such platforms is exactly the same as the set of platforms with _Float128 support, although on x86_64, x86 and ia32 the _Float64x format is Intel extended rather than binary128.) The API provided corresponds exactly to that provided for _Float128, mostly coming from TS 18661-3. As these functions always alias those for another type (long double, _Float128 or both), __* function names are not provided, as in other cases of alias types. Given the preparation done in previous patches, this one just enables the feature via Makeconfig and bits/floatn.h, adds symbol versions, and updates documentation and ABI baselines. The symbol versions are present unconditionally as GLIBC_2.27 in the relevant Versions files, as it's OK for those to specify versions for functions that may not be present in some configurations; no additional complexity is needed unless in future some configuration gains support for this type that didn't have such support in 2.27. The Makeconfig additions for ia64 and x86 aren't strictly needed, as those configurations also get float64x-alias-fcts definitions from sysdeps/ieee754/float128/Makeconfig, but still seem appropriate given that _Float64x is not _Float128 for those configurations. A libm-test-ulps update for x86 is included. This is because bits/mathinline.h does not have _Float64x support added and for two functions the use of out-of-line functions results in increased ulps (ifloat64x shares ulps with ildouble / ifloat128 as appropriate). Given that we'd like generally to eliminate bits/mathinline.h optimizations, preferring to have such optimizations in GCC instead, it seems reasonable not to add such support there for new types. GCC support for _FloatN / _FloatNx built-in functions is limited, but has been improved in GCC 8, and at some point I hope the full set of libm built-in functions in GCC, and other optimizations with per-floating-type aspects, will be enabled for all _FloatN / _FloatNx types.

Tested for x86_64, including in conjunction with _Float64x support patches, and also tested build for other configurations (in conjunction with _Float64x support patches) with build-many-glibcs.py to cover the various different files needing updating to define these aliases. * stdlib/strtold.c [__HAVE_FLOAT64X_LONG_DOUBLE] (strtof64x): Define and later undefine as macro. Define as weak alias if [!USE_WIDE_CHAR]. [__HAVE_FLOAT64X_LONG_DOUBLE] (wcstof64x): Define and later undefine as macro. Define as weak alias if [USE_WIDE_CHAR]. * sysdeps/ieee754/float128/strtof128.c: Include <bits/floatn.h>. [__HAVE_FLOAT64X && !__HAVE_FLOAT64X_LONG_DOUBLE] (strtof64x): Define and later undefine as macro. Define as weak alias if [!USE_WIDE_CHAR]. [__HAVE_FLOAT64X && !__HAVE_FLOAT64X_LONG_DOUBLE] (wcstof64x): Define and later undefine as macro. Define as weak alias if [USE_WIDE_CHAR]. * sysdeps/ieee754/float128/strtof128_l.c [__HAVE_FLOAT64X && !__HAVE_FLOAT64X_LONG_DOUBLE] (strtof64x_l): Define and later undefine as macro. Define as weak alias if [!USE_WIDE_CHAR]. [__HAVE_FLOAT64X && !__HAVE_FLOAT64X_LONG_DOUBLE] (wcstof64x_l): Define and later undefine as macro. Define as weak alias if [USE_WIDE_CHAR]. * sysdeps/ieee754/ldbl-128/strtold_l.c [__HAVE_FLOAT64X_LONG_DOUBLE] (strtof64x_l): Define and later undefine as macro. Define as weak alias if [!USE_WIDE_CHAR]. [__HAVE_FLOAT64X_LONG_DOUBLE] (wcstof64x_l): Define and later undefine as macro. Define as weak alias if [USE_WIDE_CHAR]. * sysdeps/ieee754/ldbl-64-128/strtold_l.c [__HAVE_FLOAT64X_LONG_DOUBLE] (strtof64x_l): Define and later undefine as macro. Define as weak alias if [!USE_WIDE_CHAR]. [__HAVE_FLOAT64X_LONG_DOUBLE] (wcstof64x_l): Define and later undefine as macro. Define as weak alias if [USE_WIDE_CHAR]. * sysdeps/ieee754/ldbl-96/strtold_l.c [__HAVE_FLOAT64X_LONG_DOUBLE] (strtof64x_l): Define and later undefine as macro. Define as weak alias if [!USE_WIDE_CHAR]. [__HAVE_FLOAT64X_LONG_DOUBLE] (wcstof64x_l): Define and later undefine as macro. Define as weak alias if [USE_WIDE_CHAR].
* Define __STDC_WANT_IEC_60559_TYPES_EXT__ in tst-strtod-round-skeleton.c.Joseph Myers2017-11-241-0/+1
| | | | | | | | | | | | | | | The tst-strtod-round-skeleton.c conditionals relating to handling of _Float64x require associated <float.h> macros, which requires __STDC_WANT_IEC_60559_TYPES_EXT__ to be defined before <float.h> is included if _Float64x is supported. This patch adds the necessary definition. Tested for x86_64, including in conjunction with _Float64x support patches. * stdlib/tst-strtod-round-skeleton.c (__STDC_WANT_IEC_60559_TYPES_EXT__): Define before including headers.
* Move wcstof128 symbol versions to wcsmbs/Versions.Joseph Myers2017-11-241-2/+0
| | | | | | | | | | | | | | This patch moves wcstof128 and wcstof128_l Versions file entries from stdlib/Versions to wcsmbs/Versions, which is a more appropriate place for them. Tested for x86_64, and with build-many-glibcs.py that installed stripped shared libraries are unchanged by the patch. * stdlib/Versions (libc): Move entries for wcstof128 and wcstof128_l to .... * wcsmbs/Versions (libc): ... here. Include <float128-abi.h>.
* Handle more _FloatN, _FloatNx types in type-generic strtod tests.Joseph Myers2017-11-072-12/+91
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Continuing the preparation for additional _FloatN / _FloatNx type support, this patch adds support to type-generic strtod tests. GEN_STRTOD_TEST_FOREACH and STRTOD_TEST_FOREACH are made to handle the full set of such types. tst-strtod-round-skeleton.c is updated for those types it can handle without needing changes to the generator (i.e. those types that have already-handled formats). Tested for x86_64. * stdlib/tst-strtod.h (F16): New macro. (F32): Likewise. (F64): Likewise. (F32X): Likewise. (F64X): Likewise. (F128X): Likewise. (IF_FLOAT16): Likewise. (IF_FLOAT32): Likewise. (IF_FLOAT64): Likewise. (IF_FLOAT32X): Likewise. (IF_FLOAT64X): Likewise. (IF_FLOAT128X): Likewise. (GEN_TEST_STRTOD_FOREACH): Conditionally call macros for _Float16, _Float32, _Float64, _Float32x, _Float64x and _Float128x. (STRTOD_TEST_FOREACH): Likewise. * stdlib/tst-strtod-round-skeleton.c (CHOOSE_f32): New macro. (CHOOSE_f64): Likewise. (CHOOSE_f32x): Likewise. (CHOOSE_f64x): Likewise.
* Declare strtof, strfromf functions for more _FloatN, _FloatNx types.Joseph Myers2017-11-031-2/+117
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Continuing the preparation for additional _FloatN / _FloatNx type support, this patch arranges for <stdlib.h> to declare strtof and strfromf functions for all such types, similarly to the declarations already present for _Float128. Tested for x86_64. * stdlib/stdlib.h [__HAVE_FLOAT16 && __GLIBC_USE (IEC_60559_TYPES_EXT)] (strtof16): Declare. [__HAVE_FLOAT32 && __GLIBC_USE (IEC_60559_TYPES_EXT)] (strtof32): Likewise. [__HAVE_FLOAT64 && __GLIBC_USE (IEC_60559_TYPES_EXT)] (strtof64): Likewise. [__HAVE_FLOAT32X && __GLIBC_USE (IEC_60559_TYPES_EXT)] (strtof32x): Likewise. [__HAVE_FLOAT64X && __GLIBC_USE (IEC_60559_TYPES_EXT)] (strtof64x): Likewise. [__HAVE_FLOAT128X && __GLIBC_USE (IEC_60559_TYPES_EXT)] (strtof128x): Likewise. [__HAVE_FLOAT16 && __GLIBC_USE (IEC_60559_TYPES_EXT)] (strfromf16): Likewise. [__HAVE_FLOAT32 && __GLIBC_USE (IEC_60559_TYPES_EXT)] (strfromf32): Likewise. [__HAVE_FLOAT64 && __GLIBC_USE (IEC_60559_TYPES_EXT)] (strfromf64): Likewise. [__HAVE_FLOAT32X && __GLIBC_USE (IEC_60559_TYPES_EXT)] (strfromf32x): Likewise. [__HAVE_FLOAT64X && __GLIBC_USE (IEC_60559_TYPES_EXT)] (strfromf64x): Likewise. [__HAVE_FLOAT128X && __GLIBC_USE (IEC_60559_TYPES_EXT)] (strfromf128x): Likewise. [__USE_GNU && __HAVE_FLOAT16] (strtof16_l): Likewise. [__USE_GNU && __HAVE_FLOAT32] (strtof32_l): Likewise. [__USE_GNU && __HAVE_FLOAT64] (strtof64_l): Likewise. [__USE_GNU && __HAVE_FLOAT32X] (strtof32x_l): Likewise. [__USE_GNU && __HAVE_FLOAT64X] (strtof64x_l): Likewise. [__USE_GNU && __HAVE_FLOAT128X] (strtof128x_l): Likewise.
