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.)

2012-06-06MIPS: Convert __syscall_error() callers to use $a0 for argumentKevin Cernekee

2012-06-06ldso: preload standard path library with setuid bit setFilippo Arcidiacono
For set-user-ID/set-group-ID ELF binaries, only libraries in the standard search directories that are also set-user-ID must be loaded. This patch fixes existing logic according to the above statement. Furthermore if either library setuid bit isn't set or it cannot be found in the standard search path, the library won't be preloaded but execution go ahead with default one.

2012-06-06Clean up DSBT supportMark Salter
The existing DSBT support relies on the kernel to provide DSBT info as part of the load maps passed to user space. The problem with this approach is that the DSBT info is in the dynamic section, so the kernel must access a userspace mapping of the dynamic section (or separately read a copy for the kernel) in order to retrieve the information needed by userspace. This patch reworks the DSBT support to remove the reliance on DSBT info coming from the kernel. Instead, ldso reads the info itself from the dynamic section. One other benefit of this is that it allows the existing kernel FDPIC loader to also load DSBT binaries.

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.
