* Tighten up vfprintf width, precision, and total length overflow handling.David S. Miller2012-04-024-39/+131
| | | | | | | | | | | | | | | | 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.

* Preserve SSE registers in runtime relocations on x86-64.Ulrich Drepper2009-07-292-0/+2
| | | | | | | | | | SSE registers are used for passing parameters and must be preserved in runtime relocations. This is inside ld.so enforced through the tests in tst-xmmymm.sh. But the malloc routines used after startup come from libc.so and can be arbitrarily complex. It's overkill to save the SSE registers all the time because of that. These calls are rare. Instead we save them on demand. The new infrastructure put in place in this patch makes this possible and efficient.
