2023-11-10newlib: libc: Fix crash on fprintf to a wide-oriented stream.Takashi Yano1-1/+5
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.

2022-07-13Add _REENT_ERRNO(ptr)Matt Joyce1-1/+1
Add a _REENT_ERRNO() macro to encapsulate the access to the _errno member of struct reent. This will help to replace the structure member with a thread-local storage object in a follow up patch. Replace uses of __errno_r() with _REENT_ERRNO(). Keep __errno_r() macro for potential users outside of Newlib.

2017-12-01newlib: vf[w]scanf: Drop width computation mixupCorinna Vinschen1-7/+12
The width value keeps the maximum field width. This is the maximum field width of the *input*. It's *never* to be used in conjunction with the number of bytes or characters written to the output argument. However, especially in vfwscanf, the code is partially taken from NetBSD which erroneously subtracts the number of multibyte chars written to the argument from the width variable, thus potentially subtracting up to MB_CUR_MAX from width for a single character in the input stream. To make matters worse, the previous patch adding %m added basically the same mistake for 'c' type input. Fix it. Signed-off-by: Corinna Vinschen <corinna@vinschen.de>

2017-11-29newlib: [w]scanf: Fix behaviour on matching failureCorinna Vinschen1-14/+2
The special handling of %\0 in [w]scanf is flawed. It's just a matching failure and should be handled as such. scanf also fakes an int input value on %X with X being an invalid conversion char. This is also just a matching failure and should be handled the same way as %\0. There's no indication of the reason for this "disgusting backwards compatibility hacks" in the logs, given this code made it into newlib before setting up the CVS repo. Just handle these cases identically as matching failures. Signed-off-by: Corinna Vinschen <corinna@vinschen.de>

- Remove charset parameter from low level __foo_wctomb/__foo_mbtowc calls. - Instead, create array of function for ISO and Windows codepages to point to function which does not require to evaluate the charset string on each call. Create matching helper functions. I.e., __iso_wctomb, __iso_mbtowc, __cp_wctomb and __cp_mbtowc are functions returning the right function pointer now. - Create __WCTOMB/__MBTOWC macros utilizing per-reent locale and replace calls to __wctomb/__mbtowc with calls to __WCTOMB/__MBTOWC. - Drop global __wctomb/__mbtowc vars. - Utilize aforementioned changes in Cygwin to get rid of charset in other, calling functions and simplify the code. - In Cygwin restrict global cygheap locale info to the job performed by internal_setlocale. Use UTF-8 instead of ASCII on the fly in internal conversion functions. - In Cygwin dll_entry, make sure to initialize a TLS area with a NULL _REENT->_locale pointer. Add comment to explain why.
