* cygwin: mmap: fix a fork failure with private, anonymous mappingsCorinna Vinschen2017-12-101-0/+7
| | | | | | | | | | | | | Rounddown incoming addr on a page boundary. Without this, we may end up with a fork error for private, anonymous maps. The reason is, we use VirtualAlloc in this case which will potentially overcommit if addr is not on a page boundary. This isn't taken into account in bookkeeping, but fixup_mmaps_after_fork will eventually stumble over this when trying to reproduce the copy-on-write pages: VirtualQuery returns a region reaching beyond the supposedly allocated address range and from there it goes downhill.

* newlib: vfwscanf: fix negation bug in %[ conversionCorinna Vinschen2017-12-041-1/+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 ^.

| | | | | | | | | | | | | * 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.

* newlib: vf[w]scanf: Drop width computation mixupCorinna Vinschen2017-12-012-70/+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>
