2012-03-26spawn: do not require C99 styleMike Frysinger
Simple style tweak to build with older standards. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2012-03-26spawn: use glibc style to keep differences downMike Frysinger
There's no point in reformatting the code style when we're sourcing most of it from glibc. Further, the changed style breaks with older compilers, and pollutes the namespace with non-double leading under- scores. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2012-03-26ldso: bfin: tweak styleMike Frysinger
No functional changes here. We don't need line continuations as gcc is smart enough to merge the multiple strings for us. Signed-off-by: Mike Frysinger <vapier@gentoo.org>
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>
2012-03-26Revert "Fix redefinition of ioperm and iopl in stubs.c and ↵Mike Frysinger
arm/{ioperm.c,iopl.c}" This reverts commit 3bcd031f97d61a8f732d865a0f4248aed2d191ab. The arm code is supposed to provide its own userspace ioperm/iopl functions. They've never had system calls for these funcs. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

Pulled assignments out of ifs, added whitespace around operation symbols. Signed-off-by: Denys Vlasenko <vda.linux@googlemail.com>
2012-03-26stubs: unified from futureBernhard Reutner-Fischer
Future branch extends stubs with ret_enosys_stub. Resolve conflicts, and use superset of future and current master. Adjust posix_fadvise* accordingly. Upon future merge, pick this master version as the final state. Signed-off-by: Bernhard Reutner-Fischer <rep.dot.nop@gmail.com>

2012-03-26inet:rpc: fix build in !NPTL caseCarmelo Amoroso
__libc_once is not available / needed when multithreading support is not enabled, so authnone_create() calls authnone_create_once() directly. When LT.{old,new} is used instead of NPTL, it needs to explicitly include <bits/libc-lock.h> to get __libc_once to be visible. Signed-off-by: Carmelo Amoroso <carmelo.amoroso@st.com>
2012-03-25ldso: use ELF_xxx()/ElfW() helpersMike Frysinger
They expand into the same code, but using the ELF_xxx()/ElfW() macros makes it much easier to spot similarities between code bases. Acked-by: Bernhard Reutner-Fischer <rep.dot.nop@gmail.com> Acked-by: Carmelo Amoroso <carmelo.amoroso@st.com> Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2012-03-25stdio: prevent retries on fclose/fflush after write errorsDenys Vlasenko
Some test results: The longer patch posted at Sun 14:46:24 +0100 made my target system unbootable. I did not attempt to troubleshoot it, as we are focusing our efforts on the shorter patch now. The shorter patch posted at Mon 01:50:27 +0100 is a good start, but it didn't completely fix the problem for me. I am posting an updated version with a few changes at the end of this message; the patched uClibc 0.9.32.1 tree passes both of my test cases. My changes: 1) Need to break out of the loop on "hard" errors. Otherwise the library call never returns: open("/dev/null", O_RDONLY) = 4 dup2(4, 1) = 1 write(1, "hello world\n", 12) = -1 EBADF (Bad file descriptor) write(1, "hello world\n", 12) = -1 EBADF (Bad file descriptor) write(1, "hello world\n", 12) = -1 EBADF (Bad file descriptor) write(1, "hello world\n", 12) = -1 EBADF (Bad file descriptor) ... 2) Move all of the error handling logic back into the "else" clause. In particular, I believe we do not want to be checking errno unless __WRITE() had indicated a failure, since the value may be undefined: if (errno == EINTR || errno == EAGAIN /* do we have other "soft" errors? */ ) { 3) Whitespace/indentation consistency. -- 8< -- From: Denys Vlasenko <vda.linux@googlemail.com> Currently, uclibc retains buffered data on stdio write errors, and subsequent fclose and fflush will try to write it out again (in most cases, in vain).

2012-01-23libc: fix signal handling in system()Richard Braun
When built without NPTL support (or for a sparc target), the system() function doesn't conform to its specification. Namely, it uses signal() to install/save/restore signal handlers, which may break applications using custom handlers installed with sigaction(). In addition, it resets the SIGCHLD handler to SIG_DFL instead of blocking the signal, which may result in "lost" signals if a custom handler was installed. Fix system() by replacing uses of signal() with appropriate calls to sigaction() and sigprocmask(). Signed-off-by: Richard Braun <rbraun@sceen.net> Signed-off-by: Mike Frysinger <vapier@gentoo.org>
