[BZ 1190] Make EOF sticky in stdio.
C99 specifies that the EOF condition on a file is "sticky": once EOF has been encountered, all subsequent reads should continue to return EOF until the file is closed or something clears the "end-of-file indicator" (e.g. fseek, clearerr). This is arguably a change from C89, where the wording was ambiguous; the BSDs always had sticky EOF, but the System V lineage would attempt to read from the underlying fd again. GNU libc has followed System V for as long as we've been using libio, but nowadays C99 conformance and BSD compatibility are more important than System V compatibility. You might wonder if changing the _underflow impls is sufficient to apply the C99 semantics to all of the many stdio functions that perform input. It should be enough to cover all paths to _IO_SYSREAD, and the only other functions that call _IO_SYSREAD are the _seekoff impls, which is OK because seeking clears EOF, and the _xsgetn impls, which, as far as I can tell, are unused within glibc. The test programs in this patch use a pseudoterminal to set up the necessary conditions. To facilitate this I added a new test-support function that sets up a pair of pty file descriptors for you; it's almost the same as BSD openpty, the only differences are that it allocates the optionally-returned tty pathname with malloc, and that it crashes if anything goes wrong. [BZ #1190] [BZ #19476] * libio/fileops.c (_IO_new_file_underflow): Return EOF immediately if the _IO_EOF_SEEN bit is already set; update commentary. * libio/oldfileops.c (_IO_old_file_underflow): Likewise. * libio/wfileops.c (_IO_wfile_underflow): Likewise. * support/support_openpty.c, support/tty.h: New files. * support/Makefile (libsupport-routines): Add support_openpty. * libio/tst-fgetc-after-eof.c, wcsmbs/test-fgetwc-after-eof.c: New test cases. * libio/Makefile (tests): Add tst-fgetc-after-eof. * wcsmbs/Makefile (tests): Add tst-fgetwc-after-eof. |

Remove miscellaneous debris from libio.
This patch eliminates a number of #if 0 and #ifdef TODO blocks, macros that are never used, macros that provide portability to substrates that lack basic things like EINVAL and off_t, and other such debris. I preserved IO_DEBUG and CHECK_FILE, even though as far as I can tell IO_DEBUG is never defined and therefore CHECK_FILE never does anything, because it seems like we might actually want to turn it _on_. Installed stripped libraries and executables are unchanged, except, again, that the line number of an assertion changes (this time it's somewhere in fileops.c). * libio/libio.h (_IO_pos_BAD, _IO_pos_0, _IO_pos_adjust): Define here, unconditionally. * libio/iolibio.h (_IO_pos_BAD): Don't define here. * libio/libioP.h: Remove #if 0 blocks. (_IO_pos_BAD, _IO_pos_0, _IO_pos_adjust): Don't define here. (_IO_va_start, COERCE_FILE, MAYBE_SET_EINVAL): Don't define. (CHECK_FILE): Don't use MAYBE_SET_EINVAL or COERCE_FILE. Fix style. * libio/clearerr.c, libio/fputc.c, libio/getchar.c: Assume weak_alias is always defined. * libio/fileops.c, libio/genops.c, libio/oldfileops.c * libio/oldpclose.c, libio/pclose.c, libio/wfileops.c: Remove #if 0 and #ifdef TODO blocks. Assume text_set_element is always defined. * libio/iofdopen.c, libio/iogetdelim.c, libio/oldiofdopen.c Use __set_errno (EINVAL) instead of MAYBE_SET_EINVAL. * libio/tst-mmap-eofsync.c: Make #if 1 block unconditional. |

Remove _IO_file_flags define.
This entirely mechanical (except for some indentation fixups) patch replaces all uses of _IO_file_flags with _flags and removes the #define. Installed stripped libraries and executables are unchanged by this patch. * libio/libio.h (_IO_file_flags): Remove macro. All uses changed to _flags. |

Remove legacy configuration knobs from libio.
This patch eliminates the "compatibility defines" _IO_UNIFIED_JUMPTABLES (always defined to 1, used in a number of #ifs which are therefore always false), _STDIO_USES_IOSTREAM (unused), __HAVE_COLUMN (unused), _IO_BE (replaced with __glibc_unlikely), and yet another redundant definition of EOF. Installed stripped libraries are unchanged by this patch. * libio/libio.h (_IO_UNIFIED_JUMPTABLES, _STDIO_USES_IOSTREAM) (__HAVE_COLUMN, _IO_BE): Don't define. (_IO_peekc_unlocked, _IO_getwc_unlocked, _IO_putwc_unlocked) (_IO_fwide_maybe_incompatible): Use __glibc_unlikely. * libio/libioP.h (EOF): Don't define. * libio/iofdopen.c, libio/iofopen.c, libio/iopopen.c * libio/iovdprintf.c, libio/oldiofdopen.c, libio/oldiofopen.c * libio/oldiopopen.c, debug/vdprintf_chk.c: Remove #if block testing _IO_UNIFIED_JUMPTABLES. |

Mechanically remove _IO_ name aliases for types and constants.
This patch mechanically removes all remaining uses, and the definitions, of the following libio name aliases: name replaced with ---- ------------- _IO_FILE FILE _IO_fpos_t __fpos_t _IO_fpos64_t __fpos64_t _IO_size_t size_t _IO_ssize_t ssize_t or __ssize_t _IO_off_t off_t _IO_off64_t off64_t _IO_pid_t pid_t _IO_uid_t uid_t _IO_wint_t wint_t _IO_va_list va_list or __gnuc_va_list _IO_BUFSIZ BUFSIZ _IO_cookie_io_functions_t cookie_io_functions_t __io_read_fn cookie_read_function_t __io_write_fn cookie_write_function_t __io_seek_fn cookie_seek_function_t __io_close_fn cookie_close_function_t I used __fpos_t and __fpos64_t instead of fpos_t and fpos64_t because the definitions of fpos_t and fpos64_t depend on the largefile mode. I used __ssize_t and __gnuc_va_list in a handful of headers where namespace cleanliness might be relevant even though they're internal-use-only. In all other cases, I used the public-namespace name. There are a tiny handful of places where I left a use of 'struct _IO_FILE' alone, because it was being used together with 'struct _IO_FILE_plus' or 'struct _IO_FILE_complete' in the same arithmetic expression. Because this patch was almost entirely done with search and replace, I may have introduced indentation botches. I did proofread the diff, but I may have missed something. The ChangeLog below calls out all of the places where this was not a pure search-and-replace change. Installed stripped libraries and executables are unchanged by this patch, except that some assertions in vfscanf.c change line numbers. * libio/libio.h (_IO_FILE): Delete; all uses changed to FILE. (_IO_fpos_t): Delete; all uses changed to __fpos_t. (_IO_fpos64_t): Delete; all uses changed to __fpos64_t. (_IO_size_t): Delete; all uses changed to size_t. (_IO_ssize_t): Delete; all uses changed to ssize_t or __ssize_t. (_IO_off_t): Delete; all uses changed to off_t. (_IO_off64_t): Delete; all uses changed to off64_t.

Remove vestiges of external build support from libio headers.
As requested by Adhemerval, this patch removes some preprocessor conditionals from the libio headers that were only relevant when building libio outside glibc. Installed stripped libraries and executables are unchanged by this patch. * libio/iolibio.h, libio/libioP.h: Remove extern "C". * libio/libio.h: Remove __BEGIN_DECLS and __END_DECLS. Remove preprocessor conditionals on _LIBC and __USE_GNU, which are always true, and __cplusplus, which is always false. |

Fix -Os putc_unlocked, fputc_unlocked linknamespace, localplt issues (bug 15105, bug 19463).
Continuing the fixes for linknamespace and localplt test failures with -Os that arise from functions not being inlined in that case, this patch fixes such failures for putc_unlocked and fputc_unlocked. libc_hidden_* are used for both functions, while namespace issues are addressed by making putc_unlocked a weak alias of hidden __putc_unlocked, which is called in the one place where namespace issues arise (and defined as an inline function in include/stdio.h). Tested for x86_64 (both without -Os to make sure that case continues to work, and with -Os to make sure all the relevant linknamespace and localplt test failures are resolved). This completes fixing the -Os linknamespace failures (at least for x86_64); localplt failures remain after this patch. 2018-02-19 Joseph Myers <joseph@codesourcery.com> [BZ #15105] [BZ #19463] * libio/fputc_u.c (fputc_unlocked): Use libc_hidden_def. * libio/putc_u.c (putc_unlocked): Rename to __putc_unlocked and define as weak alias of __putc_unlocked.

Fix -Os getc_unlocked linknamespace, localplt issues (bug 15105, bug 19463).
Continuing the fixes for linknamespace and localplt test failures with -Os that arise from functions not being inlined in that case, this patch fixes such failures for getc_unlocked. __getc_unlocked already exists; this patch makes it explicitly hidden, calls it where needed for namespace reasons, adds an inline function for it when inline functions are used and adds libc_hidden_proto / libc_hidden_weak for getc_unlocked. Tested for x86_64 (both without -Os to make sure that case continues to work, and with -Os to make sure all the relevant linknamespace and localplt test failures are resolved). Because of other such failures that remain after this patch, neither of the bugs can yet be closed.

Fix -Os ferror_unlocked linknamespace, localplt issues (bug 15105, bug 19463).
Continuing the fixes for linknamespace and localplt test failures with -Os that arise from functions not being inlined in that case, this patch fixes such failures for ferror_unlocked. The usual approach is followed of adding __ferror_unlocked (inlined when ferror_unlocked is), making calls use it when required for namespace reasons (only one such call), and using libc_hidden_proto / libc_hidden_weak for the ferror_unlocked weak alias when only localplt but not namespace issues are involved. Tested for x86_64 (both without -Os to make sure that case continues to work, and with -Os to make sure all the relevant linknamespace and localplt test failures are resolved). Because of other such failures that remain after this patch, neither of the bugs can yet be closed. [BZ #15105] [BZ #19463] * libio/ferror_u.c (ferror_unlocked): Rename to __ferror_unlocked and define as weak alias of __ferror_unlocked.

Use libc_hidden_* for fputs (bug 15105).
Among other localplt test failures when building with -Os, there are libc.so PLT references for fputs. fputs calls normally get redirected to _IO_fputs by a macro in include/stdio.h (and _IO_fputs in turn uses libc_hidden_proto), but GCC can convert an fprintf call with a constant string argument into an fputs call, which of course is then unaffected by the macro redirection. (I don't know why this issue only appears with -Os.) This patch duly adds a use of libc_hidden_proto for fputs. I see no obvious reason why the fputs macro redirection is needed at all, but this patch does not change it. Tested for x86_64 (both that it removes this particular localplt failure for -Os - but other such failures remain so the bug can't yet be closed - and that the testsuite continues to pass without -Os). [BZ #15105] * include/stdio.h [!_ISOMAC && IS_IN (libc)] (fputs): Use libc_hidden_proto. * libio/iofputs.c (fputs): Use libc_hidden_weak. |

Fix -Os feof_unlocked linknamespace, localplt issues (bug 15105, bug 19463).
Continuing the fixes for linknamespace and localplt test failures with -Os that arise from functions not being inlined in that case, this patch fixes such failures for feof_unlocked. The usual approach is followed of adding __feof_unlocked (inlined when feof_unlocked is), making calls use it when required for namespace reasons, and using libc_hidden_proto / libc_hidden_weak for the feof_unlocked weak alias when only localplt but not namespace issues are involved. In the case of getaddrinfo.c, use of __feof_unlocked needs to be conditional since that code is also used in nscd (where __feof_unlocked is not available). Tested for x86_64 (both without -Os to make sure that case continues to work, and with -Os to make sure all the relevant linknamespace and localplt test failures are resolved). Because of other such failures that remain after this patch, neither of the bugs can yet be closed.

Post-cleanup 2: minimize _G_config.h.
Nearly everything in _G_config.h is either junk or more appropriately defined elsewhere: * _G_fpos_t, _G_fpos64_t, and _G_BUFSIZ are already completely unused. * All remaining uses of _G_va_list have been changed to __gnuc_va_list. * The definition of _G_HAVE_ST_BLKSIZE/_IO_HAVE_ST_BLKSIZE has been inlined into its sole use. * The complete definition of _G_iconv_t has been moved to libio.h and renamed _IO_iconv_t (all actual users used that name). * _G_IO_IO_FILE_VERSION is vestigial; some code cares whether _IO_stdin_used exists, but nothing looks at its value. I've preserved the value as a hardwired constant in csu/init.c. This means csu/init.c no longer needs to include anything. * Many of the headers included by _G_config.h were already being included directly by either either libio.h or stdio.h; the remaining ones were moved to libio.h. * _G_HAVE_MREMAP is still relevant, because mremap genuinely is a Linux extension; it's not in POSIX and as far as I can tell it's not available on the Hurd either. I also preserved _G_HAVE_MMAP, since it's conceivable someone would want to port glibc to a MMU-less, mmap-less environment in the future. Both are now always defined to 1/0 as is the current convention, instead of the older 1/undef convention. These are the only symbols still defined in _G_config.h. * The actual inclusion of _G_config.h moves from libio.h to libioP.h, as this is where a potential override of _G_HAVE_MMAP happens. * The #ifdef logic in libioP.h controlling _IO_JUMPS_OFFSET has been simplified. After this patch, the only surviving _G_ symbols are the struct tag names _G_fpos_t and _G_fpos64_t, which are preserved for the sake of C++ mangled names in applications, and _G_HAVE_MMAP and _G_HAVE_MREMAP, which do not seem worth renaming. Installed stripped libraries are unchanged by this patch. * bits/_G_config.h: Move back to sysdeps/generic/_G_config.h. Delete all contents except for definitions of _G_HAVE_MMAP and _G_HAVE_MREMAP. Add commentary explaining those two symbols. * sysdeps/unix/sysv/linux/bits/_G_config.h: Move back to sysdeps/unix/sysv/linux/_G_config.h. Make same content change as above. * libio/libio.h: Don't include bits/_G_config.h here. Include stddef.h with __need_wchar_t defined. Include bits/types/__mbstate_t.h, bits/types/wint_t.h, and gconv.h. Define _IO_iconv_t here, directly. Don't define _IO_HAVE_ST_BLKSIZE. * libio/libioP.h: Include _G_config.h here. Move include of shlib-compat.h up with rest of includes. Simplify conditionals controlling definition of _IO_JUMPS_OFFSET. * csu/init.c: Remove always-true #if around entire file. Don't include stdio.h. Set _IO_stdin_used to hardwired constant 0x20001, and update commentary. * include/stdio.h, sysdeps/ieee754/ldbl-opt/nldbl-compat.h: Replace all uses of _G_va_list with __gnuc_va_list. * libio/filedoalloc.c: Use #if defined _STATBUF_ST_BLKSIZE instead of #if _IO_HAVE_ST_BLKSIZE. * libio/fileops.c: Test _G_HAVE_MREMAP with #if, not #ifdef. * libio/iofdopen.c, libio/iofopen.c: Test _G_HAVE_MMAP with #if, not #ifdef. |

Post-cleanup 1: move libio.h back out of bits/.
We can't go very far with libio cleanups as long as we still have _IO_MTSAFE_IO, and I am not tackling that in this patch series, but we can at least make the maze of stdio-related headers a little less complicated. In this patch, libio.h moves back out of bits/ into the top level of the libio subdirectory, and is merged with libio/bits/libio-ldbl.h (which also used to be installed) and include/libio.h. Since almost no files include libio.h directly, this is quite straightforward. libio.h is now always used with _LIBC defined, so all of the _LIBC || _GLIBCPP_USE_WCHAR_T conditionals are unnecessary. Similarly, the ifdef nest surrounding the definition of _IO_fwide_maybe_incompatible can collapse down to a single SHLIB_COMPAT check. I also took the opportunity to add some checks for configuration botches to libio.h. Installed stripped libraries are unchanged by this patch. * libio/bits/libio.h: Move back to libio/libio.h and adjust multiple-include guard to match. Merge contents of libio/bits/libio-ldbl.h and include/libio.h into this file. Remove preprocessor conditionals that are always true and/or redundant to other preprocessor conditionals in the same nest. Include shlib-compat.h unconditionally. Error out if _LIBC is not defined, or if _ISOMAC is defined, or if _IO_MTSAFE_IO is defined but _IO_lock_t_defined is not defined after including stdio.h. Use __BEGIN_DECLS/__END_DECLS. * libio/bits/libio-ldbl.h, include/bits/libio.h: Delete file. * include/stdio.h, libio/iolibio.h, libio/libioP.h: Include libio.h as <libio/libio.h> rather than as <bits/libio.h>. |

Don't install libio.h or _G_config.h.
We shipped 2.27 with libio.h and _G_config.h still installed but issuing warnings when used. Let's stop installing them early in 2.28 so that we have plenty of time to think of another plan if there are problems. The public stdio.h had a genuine dependency on libio.h for the complete definitions of FILE and cookie_io_functions_t, and a genuine dependency on _G_config.h for the complete definitions of fpos_t and fpos64_t; these are moved to single-type headers. bits/types/struct_FILE.h also provides a handful of accessor and bitflags macros so that code is not duplicated between bits/stdio.h and libio.h. All the other _IO_ and _G_ names used by the public stdio.h can be replaced with either public names or __-names. In order to minimize the risk of breaking our own compatibility code, bits/types/struct_FILE.h preserves the _IO_USE_OLD_IO_FILE mechanism exactly as it was in libio.h, but you have to define _LIBC to use it, or it'll error out. Similarly, _IO_lock_t_defined is preserved exactly, but will error out if used without defining _LIBC. Internally, include/stdio.h continues to include libio.h, and libio.h scrupulously provides every _IO_* and _G_* name that it always did, perhaps now defined in terms of the public names. This is how this patch avoids touching dozens of files throughout glibc and becoming entangled with the _IO_MTSAFE_IO mess. The remaining patches in this series eliminate most of the _G_ names. Tested on x86_64-linux; in addition to the test suite, I installed the library in a sysroot and verified that a simple program that uses stdio.h could be compiled against the installed library, and I also verified that installed stripped libraries are unchanged. * libio/bits/types/__fpos_t.h, libio/bits/types/__fpos64_t.h: New single-type headers split from _G_config.h. * libio/bits/types/cookie_io_functions_t.h * libio/bits/types/struct_FILE.h New single-type headers split from libio.h. * libio/Makefile: Install the above new headers. Don't install libio.h, _G_config.h, bits/libio.h, bits/_G_config.h, or bits/libio-ldbl.h. * libio/_G_config.h, libio/libio.h: Delete file. * libio/bits/libio.h: Remove improper-inclusion guard. Include stdio.h and don't repeat anything that it does. Define _IO_fpos_t as __fpos_t, _IO_fpos64_t as __fpos64_t, _IO_BUFSIZ as BUFSIZ, _IO_va_list as __gnuc_va_list, __io_read_fn as cookie_read_function_t, __io_write_fn as cookie_write_function_t, __io_seek_fn as cookie_seek_function_t, __io_close_fn as cookie_close_function_t, and _IO_cookie_io_functions_t as cookie_io_functions_t. Define _STDIO_USES_IOSTREAM, __HAVE_COLUMN, and _IO_file_flags here, in the "compatibility defines" section. Remove an #if 0 block. Use the "body" macros from bits/types/struct_FILE.h to define _IO_getc_unlocked, _IO_putc_unlocked, _IO_feof_unlocked, and _IO_ferror_unlocked. Move prototypes of __uflow and __overflow... * libio/stdio.h: ...here. Don't include bits/libio.h. Don't define _STDIO_USES_IOSTREAM. Get __gnuc_va_list directly from stdarg.h. Include bits/types/__fpos_t.h, bits/types/__fpos64_t.h, bits/types/struct_FILE.h, and, when __USE_GNU, bits/types/cookie_io_functions_t.h. Use __gnuc_va_list, not _G_va_list; __fpos_t, not _G_fpos_t; __fpos64_t, not _G_fpos64_t; FILE, not struct _IO_FILE; cookie_io_functions_t, not _IO_cookie_io_functions_t; __ssize_t, not _IO_ssize_t. Unconditionally define BUFSIZ as 8192 and EOF as (-1). * libio/bits/stdio.h: Add multiple-include guard. Use the "body" macros from bits/types/struct_FILE.h instead of _IO_* macros from libio.h; use __gnuc_va_list instead of va_list and __ssize_t instead of _IO_ssize_t. * libio/bits/stdio2.h: Similarly. * libio/iolibio.h: Add multiple-include guard. Include bits/libio.h after stdio.h. * libio/libioP.h: Add multiple-include guard. Include stdio.h and bits/libio.h before iolibio.h. * include/bits/types/__fpos_t.h, include/bits/types/__fpos64_t.h * include/bits/types/cookie_io_functions_t.h * include/bits/types/struct_FILE.h: New wrappers. * bits/_G_config.h, sysdeps/unix/sysv/linux/_G_config.h: Get definitions of _G_fpos_t and _G_fpos64_t from bits/types/__fpos_t.h and bits/types/__fpos64_t.h respectively. Remove improper-inclusion guards. * conform/data/stdio.h-data: Update expectations of va_list. * scripts/check-installed-headers.sh: Remove special case for libio.h and _G_config.h. |

Remove getc and putc macros from the public stdio.h.
The getc and putc macros in the public stdio.h expand to call _IO_getc and _IO_putc respectively. As _IO_getc, fgetc, and getc are all aliases for the same function, and _IO_putc, fputc, and putc are also all aliases for the same function, the macros are pointless. The C standard does not require getc and putc to be macros, so let's just not have macros. All four symbols are exported from libc.so at the same, ancient symbol version, so there should be no risks for binary compatibility. Similarly, the getchar and putchar inlines in bits/stdio.h forward to getc and putc instead of their _IO_ aliases. As a change from longstanding historical practice, this does seem like it might break _something_, so there is a note in NEWS, which is also a convenient place to advise people that if they thought getc and putc had reduced per-character overhead they should consider using getc_unlocked and putc_unlocked instead. (These are also not macros, but when optimizing, they are inlines.) * libio/stdio.h: Don't define getc or putc as macros. * libio/bits/stdio.h (getchar, putchar): Use getc and putc, not _IO_getc and _IO_putc. |

Correct improper-inclusion check in bits/libio-ldbl.h.
The patch which moved libio.h proper into the bits directory also changed the name of its guard macro, and I neglected to check whether anything depended on that name. It turns out that there is a conditionally-used bits header that looks at it; this broke the libgcc build on at least sparc64-*-* and sparcv9-*-*. * libio/bits/libio-ldbl.h: Correct check for improper inclusion. Add own multiple include guard. |

Deprecate external use of libio.h and _G_config.h.
libio.h was originally the header for a set of supported GNU extensions, but they have not been maintained as such in many years, they are now standing in the way of improvements to stdio, and we don't think there are any remaining external users. _G_config.h was never intended for public use, but predates the bits convention. Move both of these headers into the bits directory and provide stubs at top level which issue deprecation warnings. The contents of (bits/)libio.h and (bits/)_G_config.h are still exposed to external software via stdio.h; changing that requires more complex surgery than I have time to attempt right now. * libio/libio.h, libio/_G_config.h: New stub headers which issue a deprecation warning and then include <bits/libio.h>, <bits/_G_config.h> respectively. * libio/libio.h: Rename the original version of this file to libio/bits/libio.h.

ld.so: Examine GLRO to detect inactive loader [BZ #20204]
GLRO (_rtld_global_ro) is read-only after initialization and can therefore not be patched at run time, unlike the hook table addresses and their contents, so this is a desirable hardening feature. The hooks are only needed if ld.so has not been initialized, and this happens only after static dlopen (dlmopen uses a single ld.so object across all namespaces).

libio: Free backup area when it not required (BZ#22415)
Some libio operations fail to correctly free the backup area (created by _IO_{w}default_pbackfail on unget{w}c) resulting in either invalid buffer free operations or memory leaks. For instance, on the example provided by BZ#22415 a following fputc after a fseek to rewind the stream issues an invalid free on the buffer. It is because although _IO_file_overflow correctly (from fputc) correctly calls _IO_free_backup_area, the _IO_new_file_seekoff (called by fseek) updates the FILE internal pointers without first free the backup area (resulting in invalid values in the internal pointers). The wide version also shows an issue, but instead of accessing invalid pointers it leaks the backup memory on fseek/fputwc operation. Checked on x86_64-linux-gnu and i686-linux-gnu. * libio/Makefile (tests): Add tst-bz22415. (tst-bz22415-ENV): New rule. (generated): Add tst-bz22415.mtrace and tst-bz22415.check.

Disable single thread optimization for open_memstream
Single thread optimization is valid if at thread creation time the optimization can be disabled. This is in principle true for all stream objects that user code can access (and thus needs locking), using the same internal list as fflush(0) uses. However in glibc open_memstream is not on that list (BZ 21735) so the optimization has to be disabled. * libio/memstream.c (__open_memstream): Set _IO_FLAGS2_NEED_LOCK. * libio/wmemstream.c (open_wmemstream): Likewise. * nptl/tst-memstream.c: New. |

Single threaded stdio optimization
Locking overhead can be significant in some stdio operations that are common in single threaded applications. This patch adds the _IO_FLAGS2_NEED_LOCK flag to indicate if an _IO_FILE object needs to be locked and some of the stdio functions just jump to their _unlocked variant when not. The flag is set on all _IO_FILE objects when the first thread is created. A new GLIBC_PRIVATE libc symbol, _IO_enable_locks, was added to do this from libpthread. The optimization can be applied to more stdio functions, currently it is only applied to single flag check or single non-wide-char standard operations. The flag should probably be never set for files with _IO_USER_LOCK, but that's just a further optimization, not a correctness requirement. The optimization is valid in a single thread because stdio operations are non-as-safe (so lock state is not observable from a signal handler) and stdio locks are recursive (so lock state is not observable via deadlock). The optimization is not valid if a thread may be created while an stdio lock is taken and thus it should be disabled if any user code may run during an stdio operation (interposed malloc, printf hooks, etc). This makes the optimization more complicated for some stdio operations (e.g. printf), but those are bigger and thus less important to optimize so this patch does not try to do that. * libio/libio.h (_IO_FLAGS2_NEED_LOCK, _IO_need_lock): Define. * libio/libioP.h (_IO_enable_locks): Declare. * libio/Versions (_IO_enable_locks): New symbol. * libio/genops.c (_IO_enable_locks): Define.

libio: Avoid dup already opened file descriptor [BZ#21393]
As described in BZ#21398 (close as dup of 21393) report current freopen implementation fails when one tries to freopen STDIN_FILENO, STDOUT_FILENO, or STDERR_FILENO. Although on bug report the discussion leads to argue if a close followed by a freopen on the standard file is a valid operation, the underlying issue is not really the check for dup3 returned value, but rather calling it if the returned file descriptor is equal as the input one. So for a quality of implementation this patch avoid calling dup3 for the aforementioned case. It also adds a dup3 error case check for the two possible failures, with one being Linux only: EINTR and EBUSY. The EBUSY issue is better explained on this stackoverflow thread [1], but in a short it is due the internal Linux implementation which allows a race condition window for dup2 due the logic dissociation of file descriptor allocation and actual VFS 'install' operation. For both outliers failures all allocated memory is freed and a NULL FILE* is returned. With this patch the example on BZ#21398 is now actually possible (I used as the testcase for the bug report). Checked on x86_64-linux-gnu. [BZ #21393] * libio/freopen.c (freopen): Avoid dup already opened file descriptor and add a check for dup3 failure. * libio/freopen64.c (freopen64): Likewise. * libio/tst-freopen.c (do_test): Rename to do_test_basic and use libsupport.

Remove _IO_MTSAFE_IO from public headers.
_IO_MTSAFE_IO controls whether stdio is *built* with support for multithreading. In the distant past it might also have worked as a feature selection macro, allowing library *users* to select thread-safe or lock-free stdio at application build time, I haven't done the archaeology. Nowadays, defining _IO_MTSAFE_IO while using the installed headers, or in _ISOMAC mode, will cause libio.h to throw syntax errors. This patch removes _IO_MTSAFE_IO from the public headers (specifically, from libio/libio.h). The most important thing it controlled in there was whether libio.h defines _IO_lock_t itself or expects stdio-lock.h to have done it, and we do still need a inter-header communication macro for that, because stdio-lock.h can only define _IO_lock_t as a typedef. I've invented _IO_lock_t_defined, which is defined by both versions of stdio-lock.h. _IO_MTSAFE_IO also controlled the definitions of a handful of macros that _might_ count as part of the public libio.h interface. They are now unconditionally given their non-_IO_MTSAFE_IO definition in libio/libio.h, and include/libio.h redefines them with the _IO_MTSAFE_IO definition. This should minimize the odds of breaking old software that actually uses those macros. I suspect that this entire mechanism is vestigial, and that glibc won't build anymore if you *don't* define _IO_MTSAFE_IO, but that's another patchset. The bulk of libio.h is internal-use-only stuff that no longer makes sense to expose (libstdc++ gave up on making a FILE the same object as a C++ filebuf *decades* ago) but that, too, is another patchset. * libio/libio.h: Condition dummy definition of _IO_lock_t on _IO_lock_t_defined, not _IO_MTSAFE_IO. Unconditionally use the non-_IO_MTSAFE_IO definitions for _IO_peekc, _IO_flockfile, _IO_funlockfile, and _IO_ftrylockfile. Only define _IO_cleanup_region_start and _IO_cleanup_region_end if not already defined. * include/libio.h: If _IO_MTSAFE_IO is defined, redefine _IO_peekc, _IO_flockfile, _IO_funlockfile, and _IO_ftrylockfile appropriately. * sysdeps/generic/stdio-lock.h, sysdeps/nptl/stdio-lock.h: Define _IO_lock_t_defined after defining _IO_lock_t. |

getopt: eliminate __need_getopt by splitting up getopt.h.
__need_getopt is misnamed; what it really means is "we want only the getopt features specified in POSIX, not the GNU extensions". Because this code is shared with gnulib, it winds up being cleanest to split getopt.h into *four* headers. getopt_core.h and getopt_ext.h will be shared with gnulib, getopt_posix.h will be just for glibc, and each project will have its own copy of getopt.h. * posix/bits/getopt_core.h, posix/bits/getopt_ext.h: New files, intended to be shared with gnulib. * posix/bits/getopt_posix.h: New file, not intended to be shared with gnulib. * posix/getopt.h: Now just includes features.h, bits/getopt_core.h, and bits/getopt_ext.h.

Remove C++ namespace handling from glibc headers.
glibc headers include some code (not particularly consistent or systematic) to put various declarations in C++ namespaces std and __c99, if _GLIBCPP_USE_NAMESPACES is defined. As noted in <https://gcc.gnu.org/ml/libstdc++/2017-03/msg00025.html>, this macro was removed from libstdc++ in 2000. I don't expect compilation with such old versions of libstdc++ to work with current glibc headers anyway (whereas old *binaries* are expected to stay working with current glibc); this patch (which should be a no-op with any libstdc++ version postdating that removal) removes all this code from the glibc headers. The begin-end-check.pl test, whose comments say it is about checking these namespace macro calls, is also removed. The code in that test would have covered __BEGIN_DECLS / __END_DECLS as well, but if those weren't properly matched it would show up with the check-installed-headers-cxx tests, so I don't think there is an actual use for keeping begin-end-check.pl with the namespace code removed. Tested for x86_64 and x86 (testsuite, and that installed stripped shared libraries are unchanged by the patch). * misc/sys/cdefs.h (__BEGIN_NAMESPACE_STD): Remove macro.

Clean up conditionals for declaration of gets.
gets has the dubious honor of being the only C89 library feature that has been completely removed from the current C and C++ standards. glibc follows suit by not declaring it in _GNU_SOURCE mode either, but it remains present in older compatibility modes. Internally, two test cases need to see stdio.h make the declaration, but all our internal code is of course compiled under _GNU_SOURCE. This is currently kludged by duplicating the gets declaration, fortify wrapper and all, in include/stdio.h. Also, the conditional in the public headers for deciding when to declare gets is complicated and repeated in two places. This patch adds a new macro to features.h that encapsulates the complicated rule for when to declare gets. stdio.h and bits/stdio2.h then simply test __GLIBC_USE (DEPRECATED_GETS), and instead of having a duplicate gets declaration in include/stdio.h, debug/tst-chk1.c and stdio-common/tst-gets.c can force gets to be declared. * include/features.h (__GLIBC_USE_DEPRECATED_GETS): New macro. * libio/stdio.h, libio/bits/stdio2.h: Condition gets on __GLIBC_USE (DEPRECATED_GETS). Update comments to indicate gets was removed from C++ in C++14. * include/stdio.h: Remove redundant declaration of gets. * debug/tst-chk1.c, stdio-common/tst-gets.c: Force gets to be declared, since we are testing it. * stdio-common/Makefile (tst-gets.c): Compile with -Wno-deprecated-declarations. * debug/Makefile (tst-chk1.c, tst-chk2.c, tst-chk3.c, tst-chk4.cc) (tst-chk5.cc, tst-chk6.cc, tst-lfschk1.c, tst-lfschk2.c) (tst-lfschk3.c, tst-lfschk4.cc, tst-lfschk5.cc, tst-lfschk6.cc): Compile with -Wno-deprecated-declarations. |

support: Introduce new subdirectory for test infrastructure
The new test driver in <support/test-driver.c> has feature parity with the old one. The main difference is that its hooking mechanism is based on functions and function pointers instead of macros. This commit also implements a new environment variable, TEST_COREDUMPS, which disables the code which disables coredumps (that is, it enables them if the invocation environment has not disabled them). <test-skeleton.c> defines wrapper functions so that it is possible to use existing macros with the new-style hook functionality. This commit changes only a few test cases to the new test driver, to make sure that it works as expected. |

libio: Multiple fixes for open_{w}memstram (BZ#18241 and BZ#20181)
This patches fixes multiples issues on open_{w}memstream reported on both BZ#18241 and BZ#20181: - failed fseek does not set errno. - negative offset in fseek fails even when resulting position is a valid one. - a flush after write if the current write position is not at the end of the stream currupt data. The main fix is on seek operation for memstream (_IO_{w}str_seekoff), where both _IO_read_ptr and _IO_read_end pointer are updated if a write operation has occured (similar to default file operations). Also, to calculate the offset on both read and write pointers, a temporary value is instead of updating the argument supplied value. Negative offset are valid if resulting internal pointer is within the range of _IO_{read,write}_base and _IO_{read,write}_end. Also POSIX states that a null or wide null shall be appended to the current buffer iff a write moves the position to a value larger than the current lenght. Current implementation appends a null or wide null regardless of this condition. This patch fixes it by removing the 'else' condition on _IO_{w}mem_sync. Checked on x86_64. [BZ #18241] [BZ #20181] * libio/Makefile (test): Add tst-memstream3 and tst-wmemstream3. * libio/memstream.c (_IO_mem_sync): Only append a null byte if write position is at the end the buffer. * libio/wmemstream.c (_IO_wmem_sync): Likewise. * libio/strops.c (_IO_str_switch_to_get_mode): New function.

Support __STDC_WANT_LIB_EXT2__ feature test macro.
This patch implements support for the __STDC_WANT_LIB_EXT2__ feature test macro from ISO/IEC TR 24731-2:2010, thereby implementing one possible approach for supporting ISO C feature test macros. Recall that, as described in <https://sourceware.org/ml/libc-alpha/2016-05/msg00486.html>, these macros work based on the definition when affected headers are included, so cannot be handled once when the first system header is included because that might not be one of the headers the particular macro in question affects. <https://sourceware.org/ml/libc-alpha/2016-05/msg00680.html> expresses views on possible approaches for implementation and <https://sourceware.org/ml/libc-alpha/2016-06/msg00039.html> follows up on that. This patch arranges things so that the relevant condition is __GLIBC_USE (LIB_EXT2), following one of the suggestions given. Headers using these macros include <bits/libc-header-start.h>, which in turn includes <features.h>. Headers must define __GLIBC_INTERNAL_STARTING_HEADER_IMPLEMENTATION before including <bits/libc-header-start.h>, to discourage inclusion outside glibc as requested. __USE_GNU conditions on affected functions are changed to __GLIBC_USE (LIB_EXT2), while it's added as an additional alternative on the conditions for functions already enabled for some POSIX versions. It would be possible to convert existing __USE_* conditionals to __GLIBC_USE (with the relevant __GLIBC_USE_* being defined in <features.h> where __USE_* are presently defined), and so make them typo-proof (given -Wundef -Werror in glibc builds) because __GLIBC_USE is used with #if not #ifdef / #if defined. No attempt is made to enforce the rule about diagnosing different definitions of __STDC_WANT_LIB_EXT2__ when affected headers are included; such a diagnostic is incompatible with multiple-include guards on the affected headers, unless compiler extensions are added to support it. As previously noted, glibc does not implement all features from TR 24731-2:2010: the functions aswprintf vaswprintf getwdelim getwline are not in glibc, although they would be appropriate to add if someone wished to do so. But I think it makes sense to support the feature test macro if *any* of the controlled features are present in glibc. Tested for x86_64 and x86 (testsuite, and that installed stripped shared libraries are unchanged by the patch). * bits/libc-header-start.h: New file. * Makefile (headers): Add bits/libc-header-start.h. * include/features.h (__STDC_WANT_LIB_EXT2__): Document. (__GLIBC_USE): New macro. * libio/stdio.h: Define __GLIBC_INTERNAL_STARTING_HEADER_IMPLEMENTATION and include <bits/libc-header-start.h> instead of including <features.h>.

libio: Implement vtable verification [BZ #20191]
This commit puts all libio vtables in a dedicated, read-only ELF section, so that they are consecutive in memory. Before any indirect jump, the vtable pointer is checked against the section boundaries, and the process is terminated if the vtable pointer does not fall into the special ELF section. To enable backwards compatibility, a special flag variable (_IO_accept_foreign_vtables), protected by the pointer guard, avoids process termination if libio stream object constructor functions have been called earlier. Such constructor functions are called by the GCC 2.95 libstdc++ library, and this mechanism ensures compatibility with old binaries. Existing callers inside glibc of these functions are adjusted to call the original functions, not the wrappers which enable vtable compatiblity. The compatibility mechanism is used to enable passing FILE * objects across a static dlopen boundary, too. |

libio: Fix fmemopen append mode failure (BZ# 20012)
The fmemopen implementation does not account the file position correctly in append mode. The following example shows the failure: === int main () { char buf[10] = "test"; FILE *fp = fmemopen (buf, 10, "a+"); fseek (fp, 0, SEEK_SET); int gr; if ((gr = getc (fp)) != 't' || (gr = getc (fp)) != 'e' || (gr = getc (fp)) != 's' || (gr = getc (fp)) != 't' || (gr = getc (fp)) != EOF) { printf ("%s: getc failed returned %i\n", __FUNCTION__, gr); return 1; } return 0; } === This is due both how read and write operation update the buffer position, taking in consideration buffer lenght instead of maximum position defined by the open mode. This patch fixes it and also fixes fseek not returning EINVAL for invalid whence modes. Tested on x86_64 and i686. [BZ #20012] * libio/fmemopen.c (fmemopen_read): Use buffer maximum position, not length to calculate the buffer to read. (fmemopen_write): Set the buffer position based on bytes written.

Fix stdio.h namespace for pre-threads POSIX (bug 20014).
stdio.h declares flockfile, ftrylockfile, funlockfile, getc_unlocked, getchar_unlocked, putc_unlocked and putchar_unlocked if __USE_POSIX, with comments "These are defined in POSIX.1:1996.". But __USE_POSIX is actually POSIX.1:1990, and these functions should not be declared for 1990 / 1992 / 1993 POSIX, XPG3 or XPG4.

libio: Update internal fmemopen position after write (BZ #20005)
Current GLIBC fmemopen fails with a simple testcase: char buffer[500] = "x"; FILE *stream; stream = fmemopen(buffer, 500, "r+"); fwrite("fish",sizeof(char),5,stream); printf("pos-1:%ld\n",ftell(stream)); fflush(stream); printf("pos-2:%ld\n",ftell(stream)); It returns: pos-1:5 pos-2:0 Where it should return: pos-1:5 pos-2:5 This is due the internal write function does not correctly update the internal object position state and then the seek operation returns a wrong value. This patch fixes it. It fixes both BZ #20005 and BZ #19230 (marked as duplicated). A new test is added to check for such case.

Define off_t in stdio.h for XOPEN2K.
The header conformance test for stdio.h for XOPEN2K fails because the header does not define the off_t type, used in the expected declarations for fseeko and ftello. The absence of this type is not actually strictly a bug (hence no bug report being filed in Bugzilla), since POSIX didn't require the type to be declared in this header until the 2008 edition. However, the glibc convention in such cases - where the type falls under the general *_t POSIX reservation, and so it's OK to define it for all POSIX versions - is to make the headers self-contained in this regard even for the older POSIX versions not requiring the type to be defined despite including other declarations depending on the type. Thus, this patch adjusts the condition in the header and removes the XFAIL (rather than adapting the expectation to work when the functions are declared using __off_t without off_t being defined). Tested for x86_64 and x86 (testsuite, and that installed stripped shared libraries are unchanged by the patch). * libio/stdio.h (off_t): Define if [__USE_XOPEN2K], not [__USE_XOPEN2K8].

Fix stdio.h cuserid namespace (bug 19989).
stdio.h declares cuserid if __USE_XOPEN. But this was removed in the 2001 edition of POSIX. The #endif comment "Use X/Open, but not issue 6." reflects the correct logic, but does not correspond to the #ifdef. The use of a correct libc-hacker. The online archives for libc-hacker in August 2000 are broken, but the messages can be found in the qmail archives in /sourceware1/qmail/lists-sourceware/libc-hacker/archive/26 if you have shell access to sourceware. The issue showed up in August 2000 because of a warning about a non-prototype definition in sysdeps/posix/cuserid.c when there was no previous prototype declaration. Since we've now eliminated non-prototype function definitions, that issue does not apply. The other points from that discussion were about whether it should be included in _GNU_SOURCE; whether _GNU_SOURCE should include "everything"; whether deprecated interfaces such as this should be excluded from it; and whether, even given exclusion of deprecated interfaces, it should apply for deprecations in a version of POSIX that at that time had not been released. This patch follows the more conservative approach to a fix of keeping the interface in _GNU_SOURCE. That matches how L_cuserid is handled. I think there is a strong case for eliminating this interface from _GNU_SOURCE (but this may not automatically be the case for every interface removed in newer POSIX versions), but then L_cuserid should also be removed from _GNU_SOURCE (in stdio-common/stdio_lim.h.in) at the same time. Tested for x86_64 and x86 (testsuite, and that installed shared libraries are unchanged by the patch).

Convert miscellaneous function definitions to prototype style.
This patch converts various miscellaneous functions definitions in glibc, found with grep and not covered by my previous scripted conversions, from old-style K&R to prototype-style. These changes were made manually. This is not necessarily exhaustive as formatting variants may have prevented my grep from finding some such definitions. Regarding the changes to files from GMP, they may originally have been omitted when removing __STDC__ conditionals because of the files coming from another package, but (a) GMP no longer has __STDC__ conditionals there anyway and (b) we don't try to keep these files verbatim in sync with GMP (and there are licensing differences), so making the change to them in glibc seems reasonable.

Convert 113 more function definitions to prototype style (files with assertions).
This mostly automatically-generated patch converts 113 function definitions in glibc from old-style K&R to prototype-style. Following my other recent such patches, this one deals with the case of function definitions in files that either contain assertions or where grep suggested they might contain assertions - and thus where it isn't possible to use a simple object code comparison as a sanity check on the correctness of the patch, because line numbers are changed. A few such automatically-generated changes needed to be supplemented by manual changes for the result to compile. openat64 had a prototype declaration with "..." but an old-style definition in sysdeps/unix/sysv/linux/dl-openat64.c, and "..." needed adding to the generated prototype in the definition (I've filed <https://gcc.gnu.org/bugzilla/show_bug.cgi?id=68024> for diagnosing such cases in GCC; the old state was undefined behavior not requiring a diagnostic, but one seems a good idea). In addition, as Florian has noted regparm attribute mismatches between declaration and definition are only diagnosed for prototype definitions, and five functions needed internal_function added to their definitions (in the case of __pthread_mutex_cond_lock, via the macro definition of __pthread_mutex_lock) to compile on i386. After this patch is in, remaining old-style definitions are probably most readily fixed manually before we can turn on -Wold-style-definition for all builds.

Convert 69 more function definitions to prototype style (line wrap cases).

Convert 703 function definitions to prototype style.
This automatically-generated patch converts 703 function definitions in glibc from old-style K&R to prototype-style. This conversion is deliberately simplistic, excluding any tricky cases as even a patch covering only simple cases is still very large. Currently excluded are: sysdeps files (to improve test coverage for the initial patch); files containing assertions (to avoid line number changes so that generated libraries can be compared); any cases where the generated function declaration would involve lines over 79 characters and so need to be wrapped; any cases with array parameters or other cases where parameter declarators don't end with the parameter name; any other cases that my script didn't parse. I didn't try to make the ChangeLog generation indicate when function definitions are conditional; it just lists the functions changed without regard to that. Tested for x86_64 and x86 (testsuite, and that installed stripped shared libraries are unchanged by the patch). * crypt/cert.c (good_bye): Convert to prototype-style function definition.

Remove -fexceptions configure test.
There is a configure test for -fexceptions. This option was added in GCC 2.8, so the test is obsolete - and indeed plenty of code is using -fexceptions directly. This patch removes the configure test and makes all uses of $(exceptions) use -fexceptions directly. Tested for x86_64 and x86 (testsuite, and that installed shared libraries are unchanged by the patch). * configure.ac (libc_cv_gcc_exceptions): Remove configure test. * configure: Regenerated. * sysdeps/arm/configure.ac (libc_cv_gcc_exceptions): Do not set variable.

Move bits/libc-lock.h and bits/libc-lockP.h out of bits/ (bug 14912).
It was noted in <https://sourceware.org/ml/libc-alpha/2012-09/msg00305.html> that the bits/*.h naming scheme should only be used for installed headers. 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. Tested for x86_64 (testsuite, and that installed stripped shared libraries are unchanged by the patch). [BZ #14912] * bits/libc-lock.h: Move to ... * sysdeps/generic/libc-lock.h: ...here.

Don't install bits/libc-lock.h or bits/stdio-lock.h.
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>.
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. |

libio: fmemopen rewrite to POSIX compliance
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.

Use "|" instead of "+" when combine the _IO_LINE_BUF and _IO_UNBUFFERED flags
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. |

Fix swscanf vswscanf namespace (bug 18542).
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.

Fix syslog fputs_unlocked namespace (bug 18530).
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.

Fix open_memstream namespace (bug 18498).
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.
