2016-12-23remove UCLIBC_LINUX_MODULE_26Waldemar Brodkorb
The syscall wrappers are not required and other C libraries do not provide them. Busybox modutils.c must be patched so that syscall() is used for uClibc-ng. Signed-off-by: Waldemar Brodkorb <wbx@openadk.org>

2013-03-14utimes: Export utimensat based utimesVineet Gupta
sys/time.h has libc_hidden_proto(utimes) which generates the hidden "__GI_utimes" symbol reference, and common/utimes.c has a libc_hidden_def(utimes) which generates the exported "utimes" alias. As part of no-legacy-syscall kernel ABI, Commit 80dc2ed05 "utimes: Use utimensat if arch does not have the utimes syscall" introduced a new wrapper, but missed the corresponding libc_hidden_def, causing Busybox (1.20.0) link to fail (for ARC). Also don't generate a STUB, in that case. ---------------->8------------------- .... touch.c:(.text.touch_main+0xdc): undefined reference to `utimes' touch.c:(.text.touch_main+0x114): undefined reference to `utimes' libbb/lib.a(copy_file.o): In function `copy_file': copy_file.c:(.text.copy_file+0x446): undefined reference to `utimes' collect2: ld returned 1 exit status ---------------->8------------------- Signed-off-by: Vineet Gupta <vgupta@synopsys.com> Cc: Markos Chandras <markos.chandras@imgtec.com> Signed-off-by: Bernhard Reutner-Fischer <rep.dot.nop@gmail.com>
2013-02-20fstatfs: Add __libc_fstatfs wrapperMarkos Chandras
New architectures don't have fstatfs anymore, so we use a wrapper for __libc_fstatfs which will use fstatfs64 internally. The interface however needs to remain the same (i.e accepting a struct statfs as a second argument) for backwards compatibility Signed-off-by: Markos Chandras <markos.chandras@imgtec.com> Signed-off-by: Bernhard Reutner-Fischer <rep.dot.nop@gmail.com>

2012-06-10eventfd: Implement eventfd2 and fix eventfdKhem Raj
eventfd: evntfd assumes to take two arguments instead it should be one evntfd expects two therefore implement both syscalls with correct parameters Thanks Eugene Rudoy for reporting it and also providing the patch Signed-off-by: Khem Raj <raj.khem@gmail.com>
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.

2012-03-26arm: 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>
