2015-11-23mips: remove ISA choiceWaldemar Brodkorb
We don't add cpu specific CFLAGS to the build, so the ISA config symbols for MIPS are noops. Simple remove them. Reported-By: Bryan Hundven <bryanhundven@gmail.com>

2015-11-13i386: use socketcall even if newer linux exposes direct syscallsWaldemar Brodkorb
The changeset 9dea5dc921b5f4045a18c63eb92e84dc274d17eb in the Linux kernel expose the direct syscalls for sockets. For example udhcpc then will use sendto syscall directly and get an EINVAL error. Disable direct syscalls as it was done for SPARC in the past. Musl and GNU libc are not affected, as they already disable direct socket syscalls on i386.

2015-10-22alpha: add special umount2 handlingWaldemar Brodkorb
Only on Linux alpha __NR_oldumount is defined and a umount not umount2 syscall, but with two parameter is used. Add special handling for it and an alias for umount2() users. There was a discussion about this special handling, but it seems it was never committed upstream: http://marc.info/?l=linux-alpha&m=137455037930738&w=2 Runtime tested with qemu-alpha and a statically linked busybox binary.

2015-10-08xtensa: support call0 ABIMax Filippov
Most changes are mechanical replacement of 'retw' instruction with 'abi_ret' macro, defined to 'retw' or 'ret' according to ABI. Assembly code that makes calls is duplicated for call0 ABI with changed register numbers for parameters/return value and call instruction. 'entry' instructions are replaced with 'abi_entry' macro. More interesting changes: - non-leaf assembly functions (e.g. _dl_tlsdesc_dynamic, _dl_linux_resolve, SYSCALL_ERROR_HANDLER, PSEUDO) now need to preserve registers around intermediate calls they make, use temporary stack frame for that; - setjmp/longjmp only need to save and restore return address, stack pointer and callee-saved registers in the jmpbuf; - __clone and syscall functions had hardcoded offsets to parameter passed on stack, on call0 ABI they don't need stack frame, so the offset is different. Replace these offsets with FRAMESIZE macro. Signed-off-by: Max Filippov <jcmvbkbc@gmail.com>
2015-10-05libc: posix_fallocate must return an error number on failureYuriy Kolerov
posix_fallocate implementation in uClibc relies on fallocate system call - it just returns what fallocate returns. However fallocate returns -1 on failure and assigns an error number to errno variable. In the same time posix_fallocate must return an error number but not -1. What does this patch: if fallocate returns -1 then posix_fallocate returns errno. Otherwise posix_fallocate returns 0 on success. However there is a side effect - posix_fallocate sets errno on failure because fallocate does it. But POSIX does not forbid it thus it's not a problem.

2015-10-05libc: fix sign extension in fallocate()Yuriy Kolerov
For common generic syscall ABI fallocate syscall handler in kernel expects a 64-bit signed arguments for offset and len. However uClibc has 2 wrappers for this syscall: fallocate and fallocate64. On 32-bit machines fallocate (not fallocate64) expects 32-bit values of offset and len. Thus in this case uClibc's fallocate must pass to the syscall those values with sign extension. High word of 64-bit value must be 0 or 0xFFFFFFFF depending on sign of the original 32-bit value (offset or len). It is how sign extansion works - all high bits of the negative value must be 1. So on 32-bit machines uClibc's fallocate does sign extension incorrectly when 32-bit values are passed (offset or len). It just fills the second word of 64-bit value by zeros. E.g. fallocate works incorrectly when offset or length is negative value - in this case kernel thinks that positive values are passed. Solution is to call fallocate64 from fallocate and pass 32-bit values of offset and len to fallocate64. off_t type is automatically converted to off64_t with an appropriate sign extension. Then fallocate64 invokes kernel's system call properly. This error is detected in LTP's test kernel/syscalls/fallocate02: ----------->8---------- fallocate(..., 1, -1024, 1024) failed, expected errno:22: TEST_ERRNO=0 fallocate(..., 1, 1024, -1024) failed, expected errno:22: TEST_ERRNO=0 fallocate(..., 1, 12288, -1024) failed, expected errno:22: TEST_ERRNO=0 fallocate(..., 1, -24576, 1024) failed, expected errno:22: TEST_ERRNO=0 ----------->8---------- fallocate does not emit an error because negative values are passed to the kernel without sign extension and kernel thinks that it got valid positive values.

2015-10-05libc: fix setting return value and errno in fallocate()Yuriy Kolerov
fallocate system call must return 0 on success. On error, -1 is returned and errno is set to indicate the error. However there is an error in fallocate which is fixed by this patch - it does not set errno and returns invalid value on error (it returns error code instead of -1). This error is detected in LTP's test kernel/syscalls/fallocate02: ----------->8---------- fallocate(..., 1, 0, 1024) failed, expected errno:9: TEST_ERRNO=0 fallocate(..., 1, -1024, 1024) failed, expected errno:22: TEST_ERRNO=0 fallocate(..., 1, 1024, -1024) failed, expected errno:22: TEST_ERRNO=0 fallocate(..., 1, 12288, 0) failed, expected errno:22: TEST_ERRNO=0 fallocate(..., 1, 12288, -1024) failed, expected errno:22: TEST_ERRNO=0 fallocate(..., 1, -24576, 1024) failed, expected errno:22: TEST_ERRNO=0 ----------->8---------- Signed-off-by: Yuriy Kolerov <yuriy.kolerov@synopsys.com>

2015-08-27nptl_db/db_info: fix the incorrect initial size for dtvpJunling Zheng
When debugging a program on ARMv7 with thread-local storage declared using "__thread", attempting to print a thread-local variable will result in the following message: Cannot find thread-local storage for Thread <snip> (LWP <snip>), executable file /tmp/tls: capability not available This can be traced back to uclibc libpthread/nptl_db/td_thr_tls_get_addr.c which gdb uses to look up the address of the TLS. The function returns TD_NOCAPAB due to a mismatch in size between the DTV pointer and the size recorded in the db description. The problem lies in libpthread/nptl_db/db_info.c which initializes the db with the sizeof the union dtv. Instead it should be the sizeof a pointer to union dtv. Fixed the initial size for dtvp to sizeof a pointer, instead of sizeof the union.
