2012-04-17getaddrinfo(): avoid call to __check_pf() when not neededAlexander Komyagin
__check_pf() function is called from getaddrinfo() and it calls getifaddrs(), which is too much overhead especially if RSBAC-Net is enabled. So with this patch __check_pf() is being called only when AI_ADDRCONFIG hint flag is specified - just when we really need that check.

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.

2012-03-27ldso: bfin: add alias from __start to _startMike Frysinger
On Blackfin systems, we have underscore prefixes in our ABI. So instead of _start, we use __start. However, the makefile explicitly sets _start as the entry point to support toolchains that implicitly use other symbols as the default entry. It's easy enough to add a hidden alias in the Blackfin code for free to support this. 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).
