2012-04-26llseek: support __NR_llseek syscallMark Salter
Older kernels use __NR__llseek for a 64-bit lseek syscall. Newer kernels use __NR_llseek. This patch fixes the implementation of lseek64 to use the __NR_llseek syscall if it exists. Signed-off-by: Mark Salter <msalter@redhat.com> Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2012-04-26getpgrp: fix fallback handlingMark Salter
The test for generating a stub for getpgrp was wrong and would result in duplicate symbols when building without __NR_getpgrp, but with __NR_getpgid and __NR_getpid. A closer look at the getpgrp implementation using getpgid showed that getpid was being called to pass the current pid to getpgid. This is unnecessary because passing 0 to getpgid returns the pgid of the current process. This patch cleans up the getpgrp implementation and the stub test.

2012-04-26mmap64: Use correct type for offset parameterMike Frysinger
Some arches check the size in INLINE_SYSCALL() and barf if it's too big (i.e. a 64bit value getting truncated to 32bit). Satisfy error-check on ppc32. Signed-off-by: Bernhard Reutner-Fischer <rep.dot.nop@gmail.com> Signed-off-by: Mike Frysinger <vapier@gentoo.org>

2012-04-11mmap64: include stdint.h for uint64_tMike Frysinger
Some targets include this implicitly, but pull it in explicitly for those which don't to fix building for them. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2012-04-10mmap64: always use unsigned 64bit offsetsMike Frysinger
The current code will sometimes cast the offset to an unsigned long. On 32bit systems, that doesn't make much sense since we always know that the off64_t type is 64bits. So drop the ifdef logic, cast it to an unsigned 64bit value, and then do the shift. If the system is 32bits, and the address is still too large, then there's really nothing we could do about it anyways, so the extra ifdef logic wasn't helping.

2012-04-08signalfd.h: Use new "bits/" scheme for arch-specific flagsKevin Cernekee
glibc has split off the arch-specific flag definitions (like SFD_NONBLOCK) into <arch>/bits/signalfd.h, so that there are no longer multiple redundant copies of the entire header file. We will adopt the same scheme in uClibc. Special cases are included for: alpha mips sparc hppa was omitted because it has not been updated in glibc. All others use the common definition.

2012-03-26arm: disable ioperm/iopl stubsMike Frysinger
ARM always provides its own userspace funcs for ioperm/iopl. They've never had syscalls. So disable the stubs on ARM to avoid multiple definition errors. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

This is needed for stat'ing loop devices > 255 since otherwise kernel returns EOVERFLOW becasue it needs st_rdev/st_dev to be larger than 16bits but in kernel it uses __old_kernel_stat for stat syscall which has st_rdev/st_dev as unsigned short Add a testcase Signed-off-by: Khem Raj <raj.khem@gmail.com>

2011-11-23libc: do not rely upon ulimit kernel syscall.Carmelo Amoroso
On several architectures __NR_ulimit syscall number is currently defined but it is remapped onto sys_ni_syscall, while on other architectures they are not longer defined. So use {get,set}rlimit only to implement ulimit interface. It fixes LTP ulimit01 test case.
