2017-12-04newlib: vfwscanf: fix negation bug in %[ conversionCorinna Vinschen1-1/+1
Old BSD bug: While ^ is recognized and the set of matching characters is negated, the code neglects to increment the pointer pointing to the matching characters. Thus, on a negation expression like %[^xyz], the matching doesn't only stop at x, y, or z, but incorrectly also on ^. Fix this by setting the start pointer after recognizing the ^.

2017-12-01newlib: vf[w]scanf: Fix conversion multibyte <-> wchar_tCorinna Vinschen2-25/+53
* vfscanf: per POSIX, if the target type is wchar_t, the width is counted in (multibyte) characters, not in bytes. * vfscanf: Handle UTF-8 multibyte sequences converted to surrogate pairs on UTF-16 systems. * vfwscanf: Don't count high surrogates in input against field width counting. Per POSIX, input is Signed-off-by: Corinna Vinschen <corinna@vinschen.de>
2017-12-01newlib: vf[w]scanf: Drop width computation mixupCorinna Vinschen2-70/+44
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>

* The new code is guarded with _WANT_IO_POSIX_EXTENSIONS, but this is automatically enabled with _WANT_IO_C99_FORMATS for now. * vfscanf neglects to implement %l[, so %ml[ is not implemented yet either. * Sidenote: vfwscanf doesn't allow ranges in %[ yet.

2017-11-30newlib: vf[w]scanf: add validity checksCorinna Vinschen2-0/+37
POSIX requires that directive characters appear in a certain sequence: 1. '%' or '%<n>$' 2. optional '*' 3. optional field width digits 4. optional 'm' (not yet implemented) 5. optional length modifier ('l', 'L', 'll', 'h', 'hh', 'j', 't', 'z') 6. conversion specifier ('d', 's', etc) Add a few basic validity checks to that effect, otherwise reject directive as match failure.

2017-11-29ssp: add Object Size Checking common codeYaakov Selkowitz3-1/+107
The Object Size Checking (-D_FORTIFY_SOURCE=*) functionality provides wrappers around functions suspectible to buffer overflows. While independent from Stack Smashing Protection (-fstack-protector*), they are often used and implemented together. While GCC also provides an implementation in libssp, it is completely broken (CVE-2016-4973, RHBZ#1324759) and seemingly unfixable, as there is no reliable way for a preprocessor macro to trigger a link flag. Therefore, adding this here is necessary to make it work. Note that this does require building gcc with --disable-libssp and gcc_cv_libc_provides_ssp=yes.
