Fixes compile errors with latest util-linux.

mkostemp(char *template, int flags) generates a unique temporary
filename from a template. The flags parameter accepts three of
the same flags as open(2): O_APPEND, O_CLOEXEC, and O_SYNC. The
current implementation of mkostemp(3) does not respect the flags
and in fact confuses the flags with the file mode which should
always be S_IRUSR | S_IWUSR. This patch corrects this issue.

We were relying on FE_DIVBYZERO being turned off when printing
"%f", +-.0
Avoid the whole issue by looking at the sign-bit (in a rough
approximation).
Note that we do not handle gracefully:
printf ("\n%llf\n", -0.0);
printf ("\n%llf\n", 0.0);
nor %Lf for both when NOT cast to long double. Avoiding an FPE due to
broken numbers like these does not make sense to me.

The GNU variant of getopt() previously had no way to turn off
getopt_long() support.

mknod() in glibc/eglibc will check the argument, like this,
...
if (k_dev != dev) {
__set_errno (EINVAL);
return -1;
}
...
So add argument check in uclibc's mknod() too.

Called getpid() When creating a new process with clone(), getpid() returns
the father_process's value. It should be child_process's value.
The reason is missing a RESET_PID in the arm clone impl.

statfs() is a Linux-specific function. When building without
UCLIBC_LINUX_SPECIFIC set, libc_hidden_proto(statfs) in
include/sys/statfs.h is unmatched with libc_hidden_def(statfs)
in libc/sysdeps/linux/common/statfs.c, leading to a compile
error. This patch fixes this, as well as adds statfs() to the
list of Linux-specific functions in extra/Configs/Config.in.

If reg.h exist, gdbserver fails to compile.
I am not sure if this header file is needed for anything.
|
|
It was added in 6d6bd8ba78434ecb09395582b5f3e41febd4d4ee,
but it is unclear for me, why this is needed or if it is
required. I don't think we should depend on some gcc
optimization, which might change in the future.
Anyway, this breaks c6x toolchain building (ICE), so I remove it.
Testsuite run for supported architectures didn't add any
new errors.

We add the Linux-specific function fallocate() which allows the user to
directly manipulate allocate space for a file. fallocate() can operate
in different modes, but the default mode is equivalent to posix_fallocate()
which is specified in POSIX.1.
Recent releases of e2fsprogs 1.42.11 and above expect fallocate64() to be
available.

This reverts commit 1db4f8f8389f6a935ecd83aff7fcce5d1cf2c0f3.
It is unclear in which way this is breaking sparc systems.
With this change added you get following linking error:

This reverts commit f51fb26dbcceee9e48d10facc830bd4a549f6cc2.
This fixes linking error for sparc build.
While building a sparc system you get following linking error:
libc/sysdeps/linux/sparc/pipe.S:54: undefined reference to `__GI___errno_location'
Removing the HIDDEN_JUMPTARGET fixes the issue, while using gcc 4.8.3/binutils 2.24.
The definition of __errno_location was changed recently here:

When using something like this:

issetugid() returns 1 if the process environment or memory address space
is considered tainted, and returns 0 otherwise. This happens, for example,
when a process's privileges are elevated by the setuid or setgid flags on
an executable belonging to root. This function first appeard in OpenBSD 2.0
and is needed for the LibreSSL.
This patch follows the same logic as the equivalent musl commit. For more

There was a runtime error in systems without large file support. Call
fseek(fd, 4096, SEEK_SET) has been failing with EINVAL, though it was
succeeding for offset = 4092. This has been happening because llseek system
call accepts 64-bit value as an offset argument and lseek function has been
ordering 32-bits words that form this offset value, according to the
endianness. However this ordering to match endianness is not required,
because llseek doesn't accept one 64-bit offset argument, it accepts two
32-bit offset argument, then stitches them into one following its
endianness. As a result on little endian system, order of words has been
swapped two time: in libc and in kernel. Thus call to fseek with offset 4096
(0x1000) was doing a system call to llseek with offset 0x1000_0000_0000. I'm
not entirely sure why then offset = 4092 hasn't been failing then.
This patch removes malicious swap of words when calling llseek.

commit 00571b43df2e "libc: posix_fadvise: restore implementation for xtensa"
enabled posix_fadvise() for all arches (it was just not generated
before).
However this also unearthed an issue introduced by ee84b8b400
"linux: posix_fadvise: use new SYSCALL_ALIGN_64BIT" which is to
referencing LFS'ish code (off64_t) w/o proper checks which causes build
to break for !LFS.
Fix this by calling posix_fadvise64() only for LFS case and open-code
it's equivalent for !LFS.

Typically kernel would set the TP register of newly created thread in
clone syscall with CLONE_SETTLS.
However this implies that:
* kernel knows of the exact TP register (which is already different for
ARCompact and ARCv2) and is a detail which becomes part of the ABI
* kernel also needs to handle the unlikely but possible case of !TLS
userspace (e.g. Android libc) case where TP reg is not reserved and
thus need not be mucked with (using ELF personality based detection)
It is better to confine this detail to userspace runtime and set TP reg
right after clone syscall returns.

Native GDB requires elf_fpregset_t to be defined, even if floating point
registers are absent. In this case we use empty structure. Additionally we
redefined prfpregset_t to use this new type.
And there has been an error: it was defined that user_regs_struct has 20
registers, while it has 40.
