2012-06-13buildsys: clean up libubacktrace linker script handlingKevin Cernekee
Currently, the installed libubacktrace linker script entry always uses HARDWIRED_ABSPATH semantics, even if HARDWIRED_ABSPATH is disabled: $ grep GROUP $PREFIX/mipsel-linux-uclibc/sys-root/usr/lib/libc.so GROUP ( libc.so.0 uclibc_nonshared.a AS_NEEDED ( ld-uClibc.so.0 ) ) GROUP ( AS_NEEDED ( /lib/libubacktrace.so.0 ) ) This causes problems when building a non-sysroot toolchain. Move the AS_NEEDED insertion into libc/Makefile.in, and add a case to the HARDWIRED_ABSPATH substitution command so libubacktrace is handled the same way as the other libraries listed in the script.

2012-06-06MIPS: Use $a0 instead of $v0 for __syscall_error() argumentKevin Cernekee
$a0 is saved across _dl_runtime_resolve(); $v0 is not. Unfortunately, __syscall_error() uses $v0 for its argument, not $a0 as is the MIPS ABI standard. This means that if lazy binding was used for __syscall_error(), the errno value in $v0 could get corrupted. The problem can be easily seen in testcases where syscalls in librt fail; when librt tries to call __syscall_error() in libc, the argument gets lost and errno gets set to a bogus value: # ./tst-mqueue1 ; echo $? mq_receive on O_WRONLY mqd_t did not fail with EBADF: Unknown error 2004684208 1 # ./tst-mqueue2 ; echo $? mq_timedreceive with too small msg_len did not fail with EMSGSIZE: Unknown error 1997360560 1 # ./tst-mqueue4 ; echo $? mq_timedsend did not fail with ETIMEDOUT: Unknown error 2008747440 1 When _dl_runtime_resolve() was taken out of the equation, the same test cases passed: # LD_BIND_NOW=y ./tst-mqueue1 ; echo $? 0 # LD_BIND_NOW=y ./tst-mqueue2 ; echo $? 0 # LD_BIND_NOW=y ./tst-mqueue4 ; echo $? 0 Changing __syscall_error() to look at $a0 instead of $v0 fixed the problem. (Note that there is also a "__syscall_error.c" file which presumably uses the standard C calling conventions, but I do not think it is used on MIPS.)

2012-05-30pread/pwrite: drop fallback funcsMike Frysinger
Linux has provided these functions since the 2.1.x era, so no need to keep these around. We'd rather find out when things are missing (and fix that) than fall back to the unsafe hacks. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

2012-05-21mmap()->sys_mmap2: do unsigned shift of offsetJames Hogan
Fix the implementation of mmap based on the mmap2 system call, to construct pgoffset from offset with an unsigned shift rather than a signed (off_t) shift. The mmap2 test in the testsuite catches this case by mmap'ing with a large offset (with the sign bit set). The signed shift repeats the sign bit making the page shift way out of range. This is already fixed similarly in mmap64(). Signed-off-by: James Hogan <james.hogan@imgtec.com> Signed-off-by: Mike Frysinger <vapier@gentoo.org>
2012-05-21stdio: implement assignment-allocation "m" characterMike Frysinger
The latest POSIX spec introduces a "m" character to allocate buffers for the user when using scanf type functions. This is like the old glibc "a" flag, but now standardized. With packages starting to use these, we need to implement it. for example: char *s; sscanf("foo", "%ms", &s); printf("%s\n", s); free(s); This will automatically allocate storage for "s", read in "foo" to it, and then display it. I'm not terribly familiar with the stdio layer, so this could be wrong. But it seems to work for me. Signed-off-by: Mike Frysinger <vapier@gentoo.org>

2012-05-05drop support for old systems lacking vforkMark Salter
Only really old systems (<=linux-2.0) lack a dedicated vfork system call. The code that is in place to support them is causing issues with newer arches that also don't provide a vfork system call -- instead, they do vfork by calling clone in userspace. If anyone cares about these really old systems, they can submit a patch to make the system work with them while not breaking newer systems.

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.

2012-04-17getaddrinfo(): 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.

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.
