2009-10-15malloc: handle size overflows in realloc()Mike Frysinger
The malloc() code checks the incoming size to make sure the header adjustment doesn't cause overflow in the size storage. Add the same check to realloc() to catch stupid stuff like realloc(..., -1).

2009-10-15sparc qops: unify & shrinkMike Frysinger
We don't really need to know the exact symbol that caused a failure as long as we know where to start looking. So unify the duplicate code between all funcs and between the sparc variants. This gives us a nice code shrink of ~95%. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

2009-10-14Fix SH bits/kernel_types.h for new kernel headers.Joseph Myers
Recent SH kernel headers merge 32-bit and 64-bit headers, changing the include guards on asm/posix_types.h in the process; update uClibc code depending on those include guards. Signed-off-by: Joseph Myers <joseph@codesourcery.com>

The syscall() impl on aeabi comes from syscall-eabi.S thus we do not need the generic syscall() impl.

2009-09-26mips: do not save variables in "hi" or "lo" across system callsDaniel Jacobowitz
The kernel does not save these registers across system calls. GCC 4.4 has gotten more aggressive about using them for temporary variables, so this shows up as intermittent crashes if you use a recent compiler.

2009-09-19sigwait: remove __sigwait and __GI_sigwait symbols - they are unusedDenys Vlasenko
sigwait is not called from any uclibc function, so "hidden symbol" trick is not needed on it. __sigwait also is never used, and it's not clear why it even existed. Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>

2009-09-15sh/user.h: clean up conflicts from kernel user.hAndrew Stubbs
This patch makes sufficient modifications to the SH sys/user.h to be able to build and run gdbserver with Linux kernel 2.6.30. The problem is that both the kernel and library headers define the same symbols, thus making it impossible in include both headers. The patch undefines the kernel symbols in favour of the library symbols. Signed-off-by: Andrew Stubbs <ams@codesourcery.com> Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2009-09-15daemon: fix up INTERNAL_SYSCALL() usageMike Frysinger
Make sure we declare the error properly in case a port uses it, and fix the invocation of exit(). Since clone() will be returning a pid, assume that the value will not have the MSB set (negative) to simplify the error test a bit more. If gcc supports it, force this function to always be heavily optimized in a bid to avoid stack usage as much as possible.

2009-09-06fstatat: fix up behavior on 32/64 bit hostsMike Frysinger
The fstatat() syscall is a little funky in that it sometimes changes name between 32 and 64 bit hosts, but it should always operate on a 64bit stat structure. So for the fstatat() function, make sure we convert it from a 64bit kstat to a 32bit stat. Along these lines, we need to restore the __xstat32_conv() function.

2009-09-06xstatconv: drop useless hidden codeMike Frysinger
