* Move bits/libc-lock.h and bits/libc-lockP.h out of bits/ (bug 14912).Joseph Myers2015-09-08148-160/+324

This patch renames bits/libc-lock.h to plain libc-lock.h and bits/libc-lockP.h to plain libc-lockP.h to follow that convention. Note that I don't know where libc-lockP.h comes from for Hurd (the Hurd libc-lock.h includes libc-lockP.h, but the only libc-lockP.h in the glibc source tree is for NPTL) - some unmerged patch? - but I updated the #include in the Hurd libc-lock.h anyway.

* MIPS: Only use .set mips* assembler directives when necessaryAndrew Bennett2015-09-086-23/+54
| | | | | | | | | | | | | | | | | | | | | | There are a few .set mips* assembler directives used in the MIPS specific sysdep code that force an instruction to be assembled for a specific ISA. The reason for these is to allow an instruction to be encoded when it might not be supported in the current ISA (when the code is run the Linux kernel will trap and emulate any unsupported instructions). Unfortunately forcing a specific ISA means that when assembling for a newer ISA, where the instruction has a different encoding, the wrong encoding will be used. * sysdeps/mips/bits/atomic.h [_MIPS_SIM == _ABIO32] (MIPS_PUSH_MIPS2): Only use .set mips2 if the current ISA is below mips2. * sysdeps/mips/sys/tas.h [_MIPS_SIM == _ABIO32] (_test_and_set): Likewise. * sysdeps/mips/nptl/tls.h (READ_THREAD_POINTER): Only use .set mips32r2 if the current ISA is below mips32r2. * sysdeps/mips/tls-macros.h (TLS_RDHWR): New define.

* Don't install bits/libc-lock.h or bits/stdio-lock.h.Joseph Myers2015-09-033-2/+5
| | | | | | | | | | | | | | The bits/libc-lock.h and bits/stdio-lock.h headers are installed, but not used by any other installed header. Accordingly, this patch stops these headers from being installed. A followup is intended to move these headers out of the bits/ namespace. Tested for x86_64 (testsuite, and that installed stripped shared libraries are unchanged by the patch). * Makefile (headers): Remove bits/libc-lock.h. * libio/Makefile (headers): Remove bits/stdio-lock.h.
* Don't include <bits/stdio-lock.h> from installed <libio.h>.Joseph Myers2015-09-035-5/+15
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Every so often someone gets confused by the fact that the installed <bits/stdio-lock.h> header includes the non-installed <lowlevellock.h> header. This inclusion is not in fact a bug, because <bits/stdio-lock.h> only gets included by any header that users should include directly if _IO_MTSAFE_IO is defined, and that's an internal define used when building libio, not a feature test macro it's valid for users to define. However, on general principles it's best to have as little as possible in the installed headers that is inapplicable for valid uses of the installed glibc. This patch moves the include of <bits/stdio-lock.h> to the internal header include/libio.h, so that even if someone defines _IO_MTSAFE_IO it won't get included. This is intended as preparation for stopping <bits/stdio-lock.h> and <bits/libc-lock.h> from being installed at all (after this patch they aren't used in any installed header; formally of course they don't need to be installed even before this patch, but stopping them being installed before removing the #include would just exacerbate the confusion described above), and then moving those out of the bits/ namespace in accordance with the principle that that namespace is only for installed headers. The tests scanf15.c and scanf17.c avoid the internal headers; after this patch that means they need to undefine _IO_MTSAFE_IO as well as _LIBC so as to get a working _IO_lock_t definition for libio.h. This brings them closer to using the headers as an installed program would, which clearly accords with the intent of those tests. Tested for x86_64 (testsuite, and that installed stripped shared libraries are unchanged by the patch). * libio/libio.h [_IO_MTSAFE_IO]: Remove include of <bits/stdio-lock.h> and commented-out include of <comthread.h>. * include/libio.h [!_ISOMAC && _IO_MTSAFE_IO]: Include <bits/stdio-lock.h>. * stdio-common/scanf15.c (_IO_MTSAFE_IO): Undefine. * stdio-common/scanf17.c (_IO_MTSAFE_IO): Likewise.

| | | | | | | | | | | | | | | | | The fix for BZ #17273 introduced a single byte of memory corruption when the line is entirely blank. It would walk back past the start of the buffer if the heap happened to be 0x20 or 0x09 and then write a NUL byte. buffer = '\n'; end_ptr = buffer; while (end_ptr[-1] == ' ' || end_ptr[-1] == '\t') end_ptr--; *end_ptr = '\0'; Fix that and rework the tests. Adding the testcase for BZ #17273 to the existing \040 parser does not really make sense as it's unrelated, and leads to confusing behavior: it implicitly relies on the new entry being longer than the previous entry (since it just rewinds the FILE*). Split it out into its own dedicated testcase instead.

* time/tst-strptime2.c: test full input range +/- 0-9999James Perkins2015-08-282-53/+185

The time/tst-strptime2.c program passes a short list of strings through strptime, validating that either the gmtoff value returned matches an expected value, or that strptime returns an expected NULL for invalid strings (for example, when the minutes portion of the string is outside of the range 00 to 59, or the sign is missing before the hours digits). In review of strptime fixes, Carlos O'Donell expressed a wish that the test function iterate through the entire range of all possible numeric strings (-9999 to +9999) which could be passed to strptime %z, and validate the correct response. Specifically, the test will look for a NULL response from strptime when: * sign ('+' or '-') is not present before the first digit (invalid format). * A sign and no digits are found (invalid format). * A sign and one digit are found (invalid format). * A sign and three digits are found (invalid format). * A sign and four digits (-9999 to +9999) are found but the last two digits (minutes) are in the range 60 to 99. The test will look for a success response from strptime with tm.tm_gmtoff matching the calculated tm_gmtoff value when: * A sign and four digits are found (-9999 to +9999), and the last two digits (minutes) are in the range 00 to 59. * A sign and two digit strings are found (-99 to +99). The test's iteration over the possible digit values results in 22223 test strings prepared, tested, and passed by strptime. The test supports a --verbose command line option which will show the test results of every test input, and a final summary of all tests.

* strptime %z: fix rounding, extend range to +/-9959 [BZ #16141]James Perkins2015-08-284-15/+40
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Topic: strptime supports a %z input field descriptor, which parses a time zone offset from UTC time into the broken-out time field tm_gmtoff. Problems: 1) In the current implementation, the minutes portion calculation is correct only for minutes evenly divisible by 3. This is because the minutes value is converted to decimal time, but inadequate precision leads to rounding which calculates results that are too low for some values. For example, due to rounding, a +1159 offset string results in an incorrect tm_gmtoff of 43128 (== 11 * 3600 + 58.8 * 60) seconds, instead of 43140 (== 11 * 3600 + 59 * 60) seconds. In contrast, a +1157 offset (minutes divisible by 3) does not cause the bug, and results in a correct tm_gmtoff of 43020. 2) strptime's %z specifier will not parse time offsets less than -1200 or greater than +1200, or if only hour digits are present, less than -12 or greater than +12. It will return NULL for offsets outside that range. These limits do not meet historical and modern use cases: * Present day exceeds the +1200 limit: - Pacific/Auckland (New Zealand) summer time is +1300. - Pacific/Kiritimati (Christmas Island) is +1400. - Pacific/Apia (Samoa) summer time is +1400. * Historical offsets exceeded +1500/-1500. * POSIX supports -2459 to +2559. * Offsets up to +/-9959 may occasionally be useful. * Paul Eggert's notes provide additional detail: - https://sourceware.org/ml/libc-alpha/2014-12/msg00068.html - https://sourceware.org/ml/libc-alpha/2014-12/msg00072.html 3) tst-strptime2, part of the 'make check' test suite, does not test for the above problems. Corrective actions: 1) In time/strptime_l.c, calculate the offset from the hour and minute portions directly, without the rounding errors introduced by decimal time. 2) Remove the +/-1200 range limit, permitting strptime to parse offsets from -9959 through +9959. 3) Add zone offset values to time/tst-strptime2.c. * Test minutes evenly divisible by three (+1157) and not evenly divisible by three (+1158 and +1159). * Test offsets near the old and new range limits (-1201, -1330, -2459, -2500, -99, -9959, +1201, +1330, +1400, +1401, +2559, +2600, +99, and +9959) The revised strptime passes all old and new tst-strptime2 tests.

* Fix wordsize-32 mmap offset for negative value (BZ#18877)Adhemerval Zanella2015-08-285-6/+82
| | | | | | | | | | | | | | | | This patch fixes the default wordsize-32 mmap implementation offset calculation for negative values. Current code uses signed shift operation to calculate the multiple size to use with syscall and it is implementation defined. Change it to use a division base on mmap page size (default being as before, 4096). Tested on armv7hf.

* Detect and select i586/i686 implementation at run-timefedora/masterH.J. Lu2015-08-277-3/+119
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We detect i586 and i686 features at run-time by checking CX8 and CMOV CPUID features bits. We can use these information to select the best implementation in ix86 multiarch. HAS_I586/HAS_I686 is true if i586/i686 instructions are available on the processor. Due to the reordering and the other nifty extensions in i686, it is not really good to use heavily i586 optimized code on an i686. It's better to use i486 code if it isn't an i586. USE_I586/USE_I686 is true if i586/i686 implementation should be used for the processor. USE_I586 is true only if i686 instructions aren't available. If i686 instructions are available, we always choose i686 or i486 implementation, in that order, and we never choose i586 implementation for i686-class processors. * sysdeps/i386/init-arch.h: New file. * sysdeps/i386/i586/init-arch.h: Likewise. * sysdeps/i386/i686/init-arch.h: Likewise. * sysdeps/x86/cpu-features.c (init_cpu_features): Set bit_I586 bit if CX8 is available.
