2015-07-16libio: Fix fmemopen 'w' mode with provided bufferAdhemerval Zanella
If 'w' mode is used with a provided buffer the fmemopen will try to find the first null byte to set as maximum internal stream size. It should be done only for append mode ('a'). Kudos for Stefan Liebler for finding this error on s390-32. * libio/fmemopen.c (__fmemopen): Fix 'w' openmode with provided buffer. * stdio-common/tst-fmemopen2.c (do_test_with_buffer): Fix typo and fail output information.
2015-07-08libio: fmemopen rewrite to POSIX complianceAdhemerval Zanella
This patch added a new fmemopen version, for glibc 2.22, that aims to be POSIX complaint. It fixes some long-stading glibc fmemopen issues, such as: * it changes the way fseek with SEEK_END works on fmemopen to seek relative to buffer size instead of first '\0'. This is default mode and 'b' opening mode does not change internal behavior (bz#6544). * fix apending opening mode to use as start position either first null byte of len specified in function call (bz#13152 and #13151). * remove binary option 'b' and internal different handling (bz#12836) * fix seek/SEE_END with negative values (bz#14292). A compatibility symbol is provided to with old behavior for older symbols version (2.2.5). * include/stdio.h (fmemopen): Remove hidden prototype. (__fmemopen): Add new hidden prototype. * libio/Makefile: Add oldfmemopen object. * libio/Versions [GLIBC_2.22]: Add new fmemopen symbol. * libio/fmemopen.c (__fmemopen): Function rewrite to be POSIX compliance. * libio/oldfmemopen.c: New file: old fmemopen implementation for symbol compatibility. * stdio-common/Makefile [tests]: Add new tst-fmemopen3. * stdio-common/psiginfo.c [psiginfo]: Call __fmemopen instead of fmemopen. * stdio-common/tst-fmemopen3.c: New file: more fmemopen tests, focus on append and read mode. * sysdeps/unix/sysv/linux/aarch64/libc.abilist [GLIBC_2.22]: Add fmemopen. * sysdeps/unix/sysv/linux/alpha/libc.abilist [GLIBC_2.22]: Likewise. * sysdeps/unix/sysv/linux/arm/libc.abilist [GLIBC_2.22]: Likewise. * sysdeps/unix/sysv/linux/i386/libc.abilist [GLIBC_2.22]: Likewise. * sysdeps/unix/sysv/linux/ia64/libc.abilist [GLIBC_2.22]: Likewise. * sysdeps/unix/sysv/linux/m68k/coldfire/libc.abilist [GLIBC_2.22]: Likewise. * sysdeps/unix/sysv/linux/m68k/m680x0/libc.abilist [GLIBC_2.22]: Likewise. * sysdeps/unix/sysv/linux/microblaze/libc.abilist [GLIBC_2.22]: Likewise. * sysdeps/unix/sysv/linux/mips/mips32/fpu/libc.abilist [GLIBC_2.22]: Likewise. * sysdeps/unix/sysv/linux/mips/mips32/nofpu/libc.abilist [GLIBC_2.22]: Likewise. * sysdeps/unix/sysv/linux/mips/mips64/n32/libc.abilist [GLIBC_2.22]: Likewise. * sysdeps/unix/sysv/linux/mips/mips64/n64/libc.abilist [GLIBC_2.22]: Likewise. * sysdeps/unix/sysv/linux/powerpc/powerpc32/fpu/libc.abilist [GLIBC_2.22]: Likewise. * sysdeps/unix/sysv/linux/powerpc/powerpc32/nofpu/libc.abilist [GLIBC_2.22]: Likewise. * sysdeps/unix/sysv/linux/powerpc/powerpc64/libc.abilist [GLIBC_2.22]: Likewise. * sysdeps/unix/sysv/linux/s390/s390-32/libc.abilist [GLIBC_2.22]: Likewise. * sysdeps/unix/sysv/linux/s390/s390-64/libc.abilist [GLIBC_2.22]: Likewise. * sysdeps/unix/sysv/linux/sh/libc.abilist [GLIBC_2.22]: Likewise. * sysdeps/unix/sysv/linux/sparc/sparc32/libc.abilist [GLIBC_2.22]: Likewise. * sysdeps/unix/sysv/linux/sparc/sparc64/libc.abilist [GLIBC_2.22]: Likewise. * sysdeps/unix/sysv/linux/tile/tilegx/tilegx32/libc.abilist [GLIBC_2.22]: Likewise. * sysdeps/unix/sysv/linux/tile/tilegx/tilegx64/libc.abilist [GLIBC_2.22]: Likewise. * sysdeps/unix/sysv/linux/tile/tilepro/libc.abilist [GLIBC_2.22]: Likewise. * sysdeps/unix/sysv/linux/x86_64/64/libc.abilist [GLIBC_2.22]: Likewise. * sysdeps/unix/sysv/linux/x86_64/x32/libc.abilist [GLIBC_2.22]: Likewise. * sysdeps/unix/sysv/linux/hppa/libc.abilist [GLIBC_2.22]: Likewise. * sysdeps/unix/sysv/linux/nios2/libc.abilist [GLIBC_2.22]: Likewise.
2015-07-08Use "|" instead of "+" when combine the _IO_LINE_BUF and _IO_UNBUFFERED flagsFeng Gao
Both of "_IO_UNBUFFERED" and "_IO_LINE_BUF" are the bit flags, but I find there are some codes looks like "_IO_LINE_BUF+_IO_UNBUFFERED", while some codes are "_IO_LINE_BUF|_IO_UNBUFFERED". I think the former is not good, even though the final result is same.
2015-06-25Fix buffer overflow for writes to memory buffer stream (bug 18549)Andreas Schwab
2015-06-17Fix swscanf vswscanf namespace (bug 18542).Joseph Myers
swscanf (added in C90 Amendment 1, present in UNIX98) calls vswscanf (added in C99, not in C90 Amendment 1 or UNIX98). This patch fixes this by using __vswscanf instead and making vswscanf into a weak alias. (I intend to add conform/ test support for C90 Amendment 1 - and various other standard versions supported by glibc but not yet by conform/ tests - at some point, once the results for currently tested standards are cleaner.) Tested for x86_64 and x86 (testsuite, and that installed stripped shared libraries are unchanged by the patch). [BZ #18542] * libio/iovswscanf.c (__vswscanf): Use libc_hidden_def. (vswscanf): Use ldbl_weak_alias instead of ldbl_strong_alias * include/wchar.h (__vswscanf): Declare. Use libc_hidden_proto. * libio/swscanf.c (__swscanf): Call __vswscanf instead of vswscanf. * conform/Makefile (test-xfail-UNIX98/wchar.h/linknamespace): Remove variable.
2015-06-17Fix getpass fflush_unlocked namespace (bug 18540).Joseph Myers
The getpass function (XPG3 / XPG4 / UNIX98) calls fflush_unlocked (not in any of those standards). This patch fixes this by making fflush_unlocked into a weak alias for __fflush_unlocked and calling __fflush_unlocked from getpass. Tested for x86_64 and x86 (testsuite, and that disassembly of installed stripped shared libraries is unchanged by the patch). [BZ #18540] * libio/iofflush.c [!_IO_MTSAFE_IO] (__fflush_unlocked): Define as strong alias of _IO_fflush. Use libc_hidden_def. * libio/iofflush_u.c (fflush_unlocked): Rename to __fflush_unlocked and define as weak alias of __fflush_unlocked. Use libc_hidden_weak. * include/stdio.h (__fflush_unlocked): Declare. Use libc_hidden_proto. * misc/getpass.c (getpass): Call __fflush_unlocked instead of fflush_unlocked. * conform/Makefile (test-xfail-UNIX98/unistd.h/linknamespace): Remove variable.
2015-06-12Fix syslog fputs_unlocked namespace (bug 18530).Joseph Myers
syslog (XSI POSIX) brings in references to fputs_unlocked (not POSIX). This patch fixes this by making fputs_unlocked into a weak alias for __fputs_unlocked and using __fputs_unlocked as needed. (No linknamespace test XFAILs are removed because there are other failures from syslog as well.) Tested for x86_64 and x86 (testsuite, and comparison of disassembly of installed stripped shared libraries). Disassembly of installed stripped shared libraries is unchanged on x86_64; on x86, I see some small changes to instruction ordering and register choice, with no apparent reason for such changes to be related to this patch, but they also seem completely harmless with no change to code size. [BZ #18530] * libio/iofputs.c [!_IO_MTSAFE_IO] (__fputs_unlocked): Define as strong alias of _IO_fputs. Use libc_hidden_def. * libio/iofputs_u.c (fputs_unlocked): Rename to __fputs_unlocked and define as weak alias of __fputs_unlocked. Use libc_hidden_weak. * include/stdio.h (__fputs_unlocked): Declare. Use libc_hidden_proto. * misc/syslog.c (__vsyslog_chk): Call __fputs_unlocked instead of fputs_unlocked.
2015-06-05Fix open_memstream namespace (bug 18498).Joseph Myers
open_memstream is new in the 2008 edition of POSIX. However, the older functions getopt, closelog and fmtmsg all bring in references to it. This patch fixes this in the usual way, making open_memstream into a weak alias of __open_memstream and calling __open_memstream from the relevant places. Tested for x86_64 and x86 (testsuite, and that disassembly of installed shared libraries is unchanged by the patch). 32-bit builds produce an XPASS for conform/POSIX/unistd.h/linknamespace after this patch (because the only cause of failure left there now is 64-bit specific); that will disappear once the 64-bit failure is resolved and the XFAIL removed at that time. [BZ #18498] * libio/memstream.c (open_memstream): Rename to __open_memstream and define as weak alias of __open_memstream. * include/stdio.h (__open_memstream): Declare. Use libc_hidden_proto. (open_memstream): Don't use libc_hidden_proto. * misc/syslog.c (__vsyslog_chk): Call __open_memstream instead of open_memstream. * posix/getopt.c (_getopt_internal_r): Likewise. * conform/Makefile (test-xfail-XPG3/stdio.h/linknamespace): Remove variable.

2014-12-10Fix tst-ftell-active-handler.c warning.Joseph Myers
A recent change to libio/tst-ftell-active-handler.c (postdating my last check for warnings on x86) introduced a format warning from a long int variable used with a %zu format. This patch fixes it by using %ld for the format to match the variable. Tested for x86. * libio/tst-ftell-active-handler.c (do_ftruncate_test): Use %ld format for long int variable.

2014-12-05libio: Fix buffer overrun in tst-ftell-active-handlerAdhemerval Zanella
On 'do_ftell_test' the code: 365 if (test_modes[i].fd_mode != O_WRONLY) 366 { 367 char tmpbuf[data_len]; 368 369 rewind (fp); 370 371 while (fgets_func (tmpbuf, sizeof (tmpbuf), fp) && !feof (fp)); The 'data_len' is calculated with wsclen and allocated as 'char'. The subsequent fgetws will then try to write at most 'data_len' wchar_t in a buffer with just data_len 'char'. This patch fixes it by allocating the tmpbuf using 'wchar_t' * data_len bytes.

Don't use K&R style for function definitions.
2014-12-04Reset cached offset when reading to end of stream (BZ #17653)Siddhesh Poyarekar
POSIX allows applications to switch file handles when a read results in an end of file. Unset the cached offset at this point so that it is queried again.
2014-12-04tst-ftell-active-handler: Open file with O_TRUNC for w modesSiddhesh Poyarekar
The test case fails to truncate the file when a file is intended to be opened in w or w+ mode. Add O_TRUNC to fix this. The test still succeeds with this change.
2014-12-04ftell: seek to end only when there are unflushed bytes (BZ #17647)Siddhesh Poyarekar
Currently we seek to end of file if there are unflushed writes or the stream is in write mode, to get the current offset for writing in append mode, which is the end of file. The latter case (i.e. stream is in write mode, but no unflushed writes) is unnecessary since it will only happen when the stream has just been flushed, in which case the recorded offset ought to be reliable. Removing that case lets ftell give the correct offset when it follows an ftruncate. The latter truncates the file, but does not change the file position, due to which it is permissible to call ftell without an intervening fseek call. Tested on x86_64 to verify that the added test case fails without the patch and succeeds with it, and that there are no additional regressions due to it. [BZ #17647] * libio/fileops.c (do_ftell): Seek only when there are unflushed writes. * libio/wfileops.c (do_ftell_wide): Likewise. * libio/tst-ftell-active-handler.c (do_ftruncate_test): New test case. (do_one_test): Call it.
2014-11-27Fix libio/bug-ungetwc1.c warning.Joseph Myers
This patch fixes a warning "variable 'wc' set but not used" in libio/bug-ungetwc1.c. The test didn't verify much about the results of the functions it called. This patch makes it check the result of getwc (thereby fixing the warning), check end of file does not arrive too late in the getwc loop, and check EOF is no longer set after ungetwc. Tested for x86_64. * libio/bug-ungetwc1.c (do_test): Verify results of getwc and feof.
2014-11-26Fix warnings in fwscanf / rewind tests.Joseph Myers
This patch fixes "set but not used" warnings in the tests libio/bug-rewind.c and libio/bug-rewind2.c by checking the return values from fwscanf and making the tests fail if those values aren't as expected. Tested for x86_64. * libio/bug-rewind.c (do_test): Check fwscanf return values. * libio/bug-rewind2.c (do_test): Likewise.

2014-11-12Fix __get_nprocs fgets_unlocked namespace (bug 17582).Joseph Myers
__get_nprocs is called from malloc code, but calls fgets_unlocked, which is not an ISO C or POSIX function. This patch fixes it to call a new __fgets_unlocked name instead. Note: there are various other uses of fgets_unlocked in glibc's libraries, and I haven't yet investigated which others might also be problematic (called directly or indirectly from standard functions) and so need to change to use __fgets_unlocked. Tested for x86_64 (testsuite, and that disassembly of installed shared libraries is unchanged by the patch).

2014-11-12Fix tzfile.c namespace (bug 17583).Joseph Myers
tzfile.c is brought in by various ISO C functions, but calls fileno, fread_unlocked and ftello, which are not ISO C functions. This patch adds names __fileno, __fread_unlocked and __ftello for those functions, making tzfile.c use those new names. Note: there are various uses of fileno elsewhere in glibc that I didn't change, although it may turn out that some of those also need to use __fileno. Tested for x86_64 with the glibc testsuite. Changed line numbers in tzfile.c cause changes in assertions, and for some reason this ends up with different instruction choice and register allocation, affecting the size of __tzfile_read and so making comparison of disassembly for libc.so problematic. [BZ #17583] * libio/fileno.c (fileno): Rename to __fileno and define as weak alias of __fileno. Use libc_hidden_weak. (__fileno): Use libc_hidden_def.

2014-11-05Modify several tests to use test-skeleton.cArjun Shankar
This patch modifies several test cases to use test-skeleton.c. It was generated by a bash script written for this purpose and thus excludes several other tests which I deemed worth a visual inspection before making the change. I intend to follow up with individual patches to the tests skipped by the script. The script itself resides at http://git.io/WODAmg and should reproduce this very patch when run against master.

2014-09-16Revert to defining __extern_inline only for gcc-4.3+ (BZ #17266)Siddhesh Poyarekar
The check for only __GNUC_STDC_INLINE__ and __GNUC_GNU_INLINE__ may not be sufficient since those flags were added during initial support for C99 inlining semantics. There is also a problem with always defining __extern_inline and __extern_always_inline, since it enables inline wrapper functions even when GNU inlining semantics are not guaranteed. This, along with the possibility of such wrappers using redirection (btowc for example) could result in compiler generating an infinitely recusrive call to the function. In fact it was such a recursion that led to this code being written the way it was; see: https://bugzilla.redhat.com/show_bug.cgi?id=186410 The initial change was to fix bugs 14530 and 13741, but they can be resolved by checking if __fortify_function and/or __extern_always_inline are defined, as it has been done in this patch. In addition, I have audited uses of __extern_always_inline to make sure that none of the uses result in compilation errors. There is however a regression in this patch for llvm, since it reverts the llvm expectation that __GNUC_STDC_INLINE__ or __GNUC_GNU_INLINE__ definition imply proper extern inline semantics. 2014-09-16 Siddhesh Poyarekar <siddhesh@redhat.com> Jakub Jelinek <jakub@redhat.com> [BZ #17266] * libio/stdio.h: Check definition of __fortify_function instead of __extern_always_inline to include bits/stdio2.h. * math/bits/math-finite.h [__USE_XOPEN || __USE_ISOC99]: Also check if __extern_always_inline is defined.

Prior to the 2.20 release, the function was just changed to fail unconditionally, in commit a1a6a401ab0a3c9f15fb7eaebbdcee24192254e8. This commit removes the function completely, including gconv bits which depend on it. This changes the gconv ABI, which is not a public interface.

2014-06-07Remove redundant C locale settings.Joseph Myers
Various glibc build / install / test code has C locale settings that are redundant with LC_ALL=C. LC_ALL takes precedence over LANG, so anywhere that sets LC_ALL=C (explicitly, or through it being in the default environment for running tests) does not need to set LANG=C. LC_ALL=C also takes precedence over LANGUAGE, since 2001-01-02 Ulrich Drepper <drepper@redhat.com> * intl/dcigettext.c (guess_category_value): Rewrite so that LANGUAGE value is ignored if the selected locale is the C locale. * intl/tst-gettext.c: Set locale for above change. * intl/tst-translit.c: Likewise. and so settings of LANGUAGE=C are also redundant when LC_ALL=C is set. One test also had LC_ALL=C in its -ENV setting, although it's part of the default environment used for tests. This patch removes the redundant settings. It removes a suggestion in install.texi of setting LANGUAGE=C LC_ALL=C for "make install"; the Makefile.in target "install" already sets LC_ALL_C so there's no need for the user to set it (and nor should there be any need for the user to set it). If some build machine tool used by "make install" uses a version of libintl predating that 2001 change, and the user has LANGUAGE set, the removal of LANGUAGE=C from the Makefile.in "install" rule could in principle affect the user's installation.

2014-06-04Include LOCPATH in default test environment.Joseph Myers
Tests run using the default $(make-test-out) automatically get GCONV_PATH and LC_ALL set, whether or not those environment variables are actually needed for the individual test. However, they do not get LOCPATH set, meaning that a large number of tests have -ENV settings just to set LOCPATH. This patch moves LOCPATH into the default environment used for all tests, on the principle that like GCONV_PATH any settings needed to use files associated with the newly built library, rather than any old installed files, are appropriate to use by default. A further motivation is that various tests using .sh files also set some combination of LC_ALL, GCONV_PATH and LOCPATH. Preferably .sh files should also use the default environment with any additions required for the individual test. Now, it was suggested in <https://sourceware.org/ml/libc-alpha/2014-05/msg00715.html> that various Makefile variables used in testing should be derived by composing the -before-env and -after-env variables used when explicit environment settings are required. With such a change, it's also natural for those variables to include the default settings (via some intermediate makefile variable also used in make-test-out). Because some .sh files only set variables that correspond to the default settings, or a subset thereof, and this applies to more of the .sh files once LOCPATH is in the default settings, doing so reduces the size of a revised version of <https://sourceware.org/ml/libc-alpha/2014-05/msg00596.html>: scripts only needing the (expanded) default settings will not need to receive the separate -before-env and -after-env variables, only the single variable they do at present. So moving LOCPATH into the default settings can reduce churn caused by subsequent patches.

2014-05-27Fix offset computation for append+ mode on switching from read (BZ #16724)Siddhesh Poyarekar
The offset computation in write mode uses the fact that _IO_read_end is kept in sync with the external file offset. This however is not true when O_APPEND is in effect since switching to write mode ought to send the external file offset to the end of file without making the necessary adjustment to _IO_read_end. Hence in append mode, offset computation when writing should only consider the effect of unflushed writes, i.e. from _IO_write_base to _IO_write_ptr. The wiki has a detailed document that describes the rationale for offsets returned by ftell in various conditions: https://sourceware.org/glibc/wiki/File%20offsets%20in%20a%20stdio%20stream%20and%20ftell

2014-03-17Change offset in fdopen only if setting O_APPENDSiddhesh Poyarekar
fdopen should only be allowed to change the offset in the file it attaches to if it is setting O_APPEND. If O_APPEND is already set, it should not change the state of the handle.
2014-03-17Fix offset caching for streams and use it for ftell (BZ #16680)Siddhesh Poyarekar
The ftell implementation was made conservative to ensure that incorrectly cached offsets never affect it. However, this causes problems for append mode when a file stream is rewound. Additionally, the 'clever' trick of using stat to get position for append mode files caused more problems than it solved and broke old behavior. I have described the various problems that it caused and then finally the solution. For a and a+ mode files, rewinding the stream should result in ftell returning 0 as the offset, but the stat() trick caused it to (incorrectly) always return the end of file. Now I couldn't find anything in POSIX that specifies the stream position after rewind() for a file opened in 'a' mode, but for 'a+' mode it should be set to 0. For 'a' mode too, it probably makes sense to keep it set to 0 in the interest of retaining old behavior. The initial file position for append mode files is implementation defined, so the implementation could either retain the current file position or move the position to the end of file. The earlier ftell implementation would move the offset to end of file for append-only mode, but retain the old offset for a+ mode. It would also cache the offset (this detail is important). My patch broke this and would set the initial position to end of file for both append modes, thus breaking old behavior. I was ignorant enough to write an incorrect test case for it too. The Change: I have now brought back the behavior of seeking to end of file for append-only streams, but with a slight difference. I don't cache the offset though, since we would want ftell to query the current file position through lseek while the stream is not active. Since the offset is moved to the end of file, we can rely on the file position reported by lseek and we don't need to resort to the stat() nonsense. Finally, the cache is always reliable, except when there are unflished writes in an append mode stream (i.e. both a and a+). In the latter case, it is safe to just do an lseek to SEEK_END. The value can be safely cached too, since the file handle is already active at this point. Incidentally, this is the only state change we affect in the file handle (apart from taking locks of course). I have also updated the test case to correct my impression of the initial file position for a+ streams to the initial behavior. I have verified that this does not break any existing tests in the testsuite and also passes with the new tests.
2014-03-17Fix up return codes for tests in tst-ftell-active-handlerSiddhesh Poyarekar
The test functions used a variable ret to store failure codes for individual tests, but the variable was incorrectly used to record other failure codes too, resulting in overwriting of the tests status. This is now fixed by making sure that the ret variable is used only for recording test failures. * libio/tst-ftell-active-handler.c (do_ftell_test): Don't mix up test status with function return status. (do_write_test): Likewise. (do_append_test): Likewise.
