2023-12-01newlib: libc: Fix memory leak in computematchjumps()Kuan-Wei Chiu1-2/+4
In cases where malloc fails for the 'g->matchjump' allocation, the code path does not handle the failure gracefully, potentially leading to a memory leak. This fix ensures proper cleanup by freeing the allocated memory for 'pmatches' before returning. Signed-off-by: Kuan-Wei Chiu <visitorckw@gmail.com>
2023-11-28newlib: filter out versions from newlib.h to simplify autoreconfMike Frysinger2-2/+5
We've been manually editing newlib.hin after generating it with autoheader to drop the version defines that we keep in the separate _newlib_version.h header. This is confusing for people, and is an easy source of mistakes/errors. Since we're already running sed on newlib.h during configure to filter out defines we don't want to expose, add the version macros there too. This way we don't have to manually edit newlib.hin. This simplifies the autoreconf step in exchange for a slightly more complicated configure+sed step, but seems worth the trade-off.
2023-11-24newlib: nl_langinfo: Fix a bug of time stuff.Takashi Yano1-4/+4
Previously, e.g. nl_langinfo(_NL_TIME_WMONTH_1) returns "February" due to the bug. Similarly, nl_langinfo(_NL_TIME_WWDAY_1) returns "Mon". This occurs because wide char month and weekday arrays are pointed off-by-one (e.g. the array wmon[12] is reffered as wmon[1-12] rather than wmon[0-11]). This patch fixes that.

2023-11-20stdio: Fix bugs in commit 3d94e07c49b5Takashi Yano27-12/+43
The commit 3d94e07c49b5 has a few bugs which cause testsuite failure in libstdc++. This is due to excess orientation check in __srefill_r() and _ungetc_r(). Further, sscanf() family also calls ssvfscanf() family with fp->_file == -1. This causes undesired orientation set/check for sscanf() family. This patch fixes these problems. Also, as in GLibC, do not set orientation in ungetc, and only set, but do not check orientation in ungetwc. Fixes: 3d94e07c49b5 ("newlib: libc: Fix crash on fprintf to a wide-oriented stream.")

2023-11-17v{fs}printf/v{fs}wprintf: create external output helpersCorinna Vinschen12-265/+467
So far, the printf family of functions has two output helper functions called __sprint_r and __sfputs_r. Both are called from all variants of vfprintf as well as vfwprintf. There are also analogue helper functions for the string-creating functions vsprintf/vswprintf called __ssprint_r and __ssputs_r. However, the helpers are built once when building vfprintf/vsprintf with the INTEGER_ONLY flag, and then they are part of the vfiprintf.c and vsiprintf.c files. The problem is this: Even if a process only calls vfwprintf or the non-INTEGER_ONLY vfprintf it will always have to include the INTEGER_ONLY vfiprintf. Otherwise the helper functions are undefined. Analogue for the string-creating functions. That's a useless waste of space by including one (or two) big, unused function, if newlib is linked in statically. Create new files to define the printf output helpers separately and split them into byte-oriented and wide-char-oriented functions. This allows to link only the required functions. Also, simplify the string output helpers and fix a potential (but unlikely) buffer overflow in __ssprint_r.

2023-11-10newlib: libc: Fix crash on fprintf to a wide-oriented stream.Takashi Yano19-40/+92
Previously, fprintf() on a wide-oriented stream crashes or outputs garbage. This is because a narrow char string which can be odd bytes in length is cast into a wide char string which should be even bytes in length in __sprint_r/__sfputs_r based on the __SWID flag. As a result, if the length is odd bytes, the reading buffer runs over the buffer length, which causes a crash. If the length is even bytes, garbage is printed. With this patch, any output to the stream which is set to different orientation fails with error just like glibc. Note that it behaves differently from other libc implementations such as BSD, musl and Solaris.

After the commit a4705d387f78, printf() for floating-point values causes a memory leak. The legacy _ldtoa_r() assumed the char pointer returned will be free'ed by Bfree(). However, gdtoa-based _ldtoa_r() returns the pointer returned by gdtoa() which should be free'ed by freedtoa(). Due to this issue, the caller of _ldtoa_r() fails to free the allocated char buffer. This is the cause of the said memory leak. https://cygwin.com/pipermail/cygwin/2023-July/254054.html This patch makes rv_alloc()/freedtoa() allocate/free the buffer in a compatible way with legacy _ldtoa_r().
