* malloc: handle size overflows in realloc()Mike Frysinger2009-10-151-0/+3
| | | | | | | | | 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). Reported-by: James Coleman <james.coleman@ubicom.com> Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* sparc qops: unify & shrinkMike Frysinger2009-10-151-51/+40
| | | | | | | | | 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>
* i386: use common INTERNAL_SYSCALL_ERROR_PMike Frysinger2009-10-151-3/+0
| | | | | | The common define has the same behavior, just formatted differently. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
* Fix SH bits/kernel_types.h for new kernel headers.Joseph Myers2009-10-141-1/+2
| | | | | | | | 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.

* mips: do not save variables in "hi" or "lo" across system callsDaniel Jacobowitz2009-09-261-2/+2
| | | | | | | | | 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.

* sigwait: remove __sigwait and __GI_sigwait symbols - they are unusedDenys Vlasenko2009-09-191-6/+5
| | | | | | | | 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>

* sh/user.h: clean up conflicts from kernel user.hAndrew Stubbs2009-09-151-0/+11
| | | | | | | | | | | | 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>
* daemon: fix up INTERNAL_SYSCALL() usageMike Frysinger2009-09-151-4/+6
| | | | | | | | | | | 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.
