2007-12-07Removed pointless initialization to 0 of DIR fieldsCarmelo Amoroso
after having added memset. Thanks to Peter Mazinger for pointing this out. Signed-off-by: Carmelo Amoroso <carmelo.amoroso@st.com>
2007-12-07I don't remember exactly why we decided to pick the caller's value ofCarmelo Amoroso
sa_restorer when SA_ONSTACK is set, but it seems to break LTP's sigaltstack testcase. Some users have reported problems with sigaltstack as well; hopefully this will fix it. Signed-off-by: Haavard Skinnemoen <hskinnemoen@atmel.com>
2007-12-05Fix opendir problem when statically linked due to a missingCarmelo Amoroso
initialization of the mutex field within DIR struct. When linked dynamically instead, __pthread_mutex_init will initialize the mutex itself. Without this fix, any call to readdir will stuck forever trying to acquire the mutex. Signed-off-by: Carmelo Amoroso <carmelo.amoroso@st.com>
2007-12-03realpath: reduce stack usage from 3*PATH_MAX (12k) to 1*PATH_MAX (4k).Denis Vlasenko
reduction is achieved by direct use of user-supplied PATH_MAX sized buffer for result (without intermediate copy) and changes in copy_buf[] usage - now it is used for both "source" pathname and link name (it works because they have to be less than PATH_MAX combined, otherwise we return NULL).

2007-11-23Add some necessary Makefile bits for UCLIBC_FORMAT_FLAT_SEP_DATA.Bernd Schmidt
2007-11-23Some shared flat improvements.Bernd Schmidt
Fix minor errors: - UCLIBC_SHARED_FLAT_ID instead of SHARED_FLAT_ID - use -Wl,-shared-lib-id properly Use libc_so.a as the source for the shared libc, in order to be able to use -mleaf-id-shared-library on the Blackfin.

2007-11-22sys/procfs.h defines a typedef for floating point registers that references anBernd Schmidt
undefined structure. This typedef is used in linuxthreads.old-db, causing a compilation failure. Fixed by defining an empty structure for it - we don't have fp regs anyway.

2007-10-23Poll with zero timeoutJoakim Tjernlund
Jean-Christian de Rivaz writes: The attached patch solve an issue I faced while using the libdbus-glib waiting for a D-Bus message or the end of a glib timer at the same time. This specific case of use generate a poll call with a zero timeout. On platformes with the glibc a zero timeout poll return immetiately even if there is no file descriptor event. But on platformes with uClibc a zero timeout poll block until a file descriptor event occurs.
2007-10-13- use the compiler-driver instead of the linkerBernhard Reutner-Fischer
- adjust setting flags accordingly to use (hardcoded, see below) -Wl, Potential improvements: *) --warn-unresolved-symbols should perhaps be used for all libs *) eventually rename LDFLAGS to CC_LDFLAGS *) probe for compiler driver's notion of flag to use for passing in linker flags (i.e. don't hardcode "-Wl,")

2007-09-28This patch will fix a problem when the same host is defined with both IPv4 andMike Frysinger
IPv6 entries in /etc/hosts. Previous only the first of these host would work, as uClibc would read the /etc/hosts file from top to bottom, failing if the first hit did not match the IP type. Now uClibc will continue reading, even if the first correct entry name, but wrong IP type fails. Thus, allowing a second correct entry name with correct IP type will result in a name resolve.

I got the library to compile with the attached patches, though dynamic loader crashes early. In buildroot I changed the architecture name by hand from sparc to sparc64, otherwise the compiler produced 32-bit files with V9 (64-bit) instructions. This configuration is not supported by QEMU, so I aimed for pure 64-bit. I think Sparc64 option needs to be added to buildroot. The _Qp_ ops seem to be required by the ABI. This and setjmp patches are just hacks to get the compilation further. The _Qp_ ops can be found in glibc, would it be OK to use those? V9 assembler requires declarations for global register use. The mem* functions in sparc32 directory did not work. They are actually used only by the hybrid 32-bit + V9 CPU configuration.

In MIPS syscall(2), .cpload was added to an the error path, but it was not enough for ABIs other then O32. Use SETUP_GP, SETUP_GP64 and RESTORE_GP64 to handle all ABIs. This patch fixes an error path of MIPS pipe(2) too.
