Get rid of NIOS support. We try to support NIOSII.
|
|
It is marked as broken and it seems you can't get
any hardware for that anymore.
|
|
I mailed with Jan-Benedict Glaw, it seems VAX on Linux
is really a lot of work todo and uClibc support didn't work ever.
|
|
No real hardware available. The project for sh64 with sh5 seems
dead since 10 years. Gcc will remove support for it soon.
|
|
.globl can be used for every architecture so remove the define.
Sync with GNU C library.
|
|
It's even no longer required for non-ported ppc64
architecture. Sync with GNU C library.
This simplify the macros in include/libc-symbols.h.
|

See here for a discussion about the problem:
https://gcc.gnu.org/bugzilla/show_bug.cgi?id=47779
Latest gcc/binutils git can generate a working uClibc-ng
toolchain. Binaries tested on Arcturus uCBF54x board via
chroot from original firmware.

Actually revert 711ad9f92c1cf992c4a3d9f4f709bd692be7789c, as
it breaks vfork() on real hardware. So the common
implementation no longer works for bfin.

An abort() is only generated when gcc does not implement
a trap handler for the target architecture.
This fixes the abort() generation. Latest gcc git master
also contains a trap handler for xtensa.

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.

of any file including <unistd.h>:

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.

stndup will copy *up to* the size parameter, not allocate a buffer of
that size, so the buffer is not necessarily large enough to fit the

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.

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.

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.

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, -1024) failed, expected errno:22: TEST_ERRNO=0

Stack unwinding that happens during NPTL thread cancellation needs
cancellable syscall wrapper functions to be compiled with -fexceptions
-fasynchronous-unwind-tables to be able to unwind to cleanup handlers
registered before syscall invocation.
Add these flags for all cancellable syscall wrappers.
