* C2x printf %wN, %wfN support (bug 24466)Joseph Myers2023-06-191-2/+54
| | | | | | | | | | | | | | | | | | ISO C2x defines printf length modifiers wN (for intN_t / int_leastN_t / uintN_t / uint_leastN_t) and wfN (for int_fastN_t / uint_fastN_t). Add support for those length modifiers (such a feature was previously requested in bug 24466). scanf support is to be added separately. GCC 13 has format checking support for these modifiers. When used with the support for registering format specifiers, these modifiers are translated to existing flags in struct printf_info, rather than trying to add some way of distinguishing them without breaking the printf_info ABI. C2x requires an error to be returned for unsupported values of N; this is implemented for printf-family functions, but the parse_printf_format interface doesn't support error returns, so such an error gets discarded by that function. Tested for x86_64 and x86.

* Support C2X printf %b, %BJoseph Myers2021-11-101-0/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | C2X adds a printf %b format (see <http://www.open-std.org/jtc1/sc22/wg14/www/docs/n2630.pdf>, accepted for C2X), for outputting integers in binary. It also has recommended practice for a corresponding %B format (like %b, but %#B starts the output with 0B instead of 0b). Add support for these formats to glibc. One existing test uses %b as an example of an unknown format, to test how glibc printf handles unknown formats; change that to %v. Use of %b and %B as user-registered format specifiers continues to work (and we already have a test that covers that, tst-printfsz.c). Note that C2X also has scanf %b support, plus support for binary constants starting 0b in strtol (base 0 and 2) and scanf %i (strtol base 0 and scanf %i coming from a previous paper that added binary integer literals). I intend to implement those features in a separate patch or patches; as discussed in the thread starting at <https://sourceware.org/pipermail/libc-alpha/2020-December/120414.html>, they will be more complicated because they involve adding extra public symbols to ensure compatibility with existing code that might not expect 0b constants to be handled by strtol base 0 and 2 and scanf %i, whereas simply adding a new format specifier poses no such compatibility concerns. Note that the actual conversion from integer to string uses existing code in _itoa.c. That code has special cases for bases 8, 10 and 16, probably so that the compiler can optimize division by an integer constant in the code for those bases. If desired such special cases could easily be added for base 2 as well, but that would be an optimization, not actually needed for these printf formats to work. Tested for x86_64 and x86. Also tested with build-many-glibcs.py for aarch64-linux-gnu with GCC mainline to make sure that the test does indeed build with GCC 12 (where format checking warnings are enabled for most of the test).

* Tighten up vfprintf width, precision, and total length overflow handling.David S. Miller2012-04-021-12/+30
| | | | | | | | | | | | | | | | With help from Paul Eggert, Carlos O'Donell, and Roland McGrath. * stdio-common/printf-parse.h (read_int): Change return type to 'int', return -1 on INT_MAX overflow. * stdio-common/vfprintf.c (vfprintf): Validate width and precision against overflow of INT_MAX. Set errno to EOVERFLOW when 'done' overflows INT_MAX. Check for overflow of in-format-string precision values properly. Use EOVERFLOW rather than ERANGE throughout. Use SIZE_MAX not INT_MAX for integer overflow test. * stdio-common/printf-parsemb.c: If read_int signals an overflow, skip the construct in the format string but do not record anything. * stdio-common/bug22.c: Adjust to test both width/prevision INT_MAX overflow as well as total length INT_MAX overflow. Check explicitly for proper errno values.
