mkostemp: fix implementation

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.

lseek: Correct order of offset arguments

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.

However this implies that:
* kernel knows of the exact TP register (which is already different for

5 years agoweak symbols need to be "defined" weak but "declared" strong
Vineet Gupta [Wed, 16 Apr 2014 10:36:01 +0000 (16:06 +0530)]
weak symbols need to be "defined" weak but "declared" strong

Patch "LT.old: Make __errno_location/__h_errno_location thread safe"
uncovered yet another bug with static linking and errno (hopefully this
is last of them all).

Currently, __errno_location is declared weak but is defined strong.
While this provides with the desired weak semantics in dso, it
is subtly broken in static links.

Quoting Joern Rennecke (ARC gcc expert):

| I think the issue is that you declare the function as weak in the
| header file.  That is a rare instance where you want the reference
| use declaration that differs a bit from the definition.
| If the reference uses a weakly declared function, that creates a
| weakref, i.e. the linker won't bother to look for this symbol at
|  all - if it gets linked in for some other reason, fine,
| otherwise, it stays zero.

So the solution to declare strong, define weak.

Supporting data
-----------------
orig code: ARM mmap wrapper (LT.old build + my prev patch for errno)

_mmap:
    @ args = 8, pretend = 0, frame = 0
    @ frame_needed = 0, uses_anonymous_args = 0
    stmfd    sp!, {r4, r5, r7, lr}
    ldr    r5, [sp, #20]
    movs    ip, r5, asl #20
    beq    .L2
    bl    __errno_location(PLT)
    mov    r3, #22
    str    r3, [r0, #0]
    mvn    r0, #0
...
...
   .weak __errno_location

A statically linked hello world program which uses mmap too.
As we can see__errno_location is completely gone - which is
semantically wrong - we need functional errno.

00008274 <__GI_mmap>:
    8274:    e92d40b0     push    {r4, r5, r7, lr}
    8278:    e59d5014     ldr    r5, [sp, #20]
    827c:    e1b0ca05     lsls    ip, r5, #20
    8280:    0a000004     beq    8298
    8284:    e320f000     nop    {0}
          ^^^^^^^^^^
    8288:    e3a03016     mov    r3, #22
    828c:    e5803000     str    r3, [r0]
    8290:    e3e00000     mvn    r0, #0

This in turn is due to a fixup in ARM ld which transforms branch-to-null
into a nop. It is better than crashing but still wrong since errno
handling is removed.

With the patch, errno_location is restored back in test program.

LT.old: Make __errno_location/__h_errno_location thread safe

WHY: errno in uClibc is not thread safe

HOW: __errno_location and it's sibling __h_errno_location need to be called
     via PLT - even from within libc. That way when linked with pthread,
     intra-uClibc callers will also use the thread safe version.

     This is achieved by removing the GI alias for these functions,
     ensuring that they get called normally (via PLT)

Verified with ARC LT.old and ARM cubieboard2 buildroot (LT.old)
NPTL is unaffected by this bug.

------------ History behind this patch ---------------------

This is a long standing bug (https://bugs.busybox.net/show_bug.cgi?id=2089)

Others have tried to fix it in past (alteast Peter Korsgaard's patch in 2010),
but somehow failed to be merged (or were backed out afterwards).
http://lists.uclibc.org/pipermail/uclibc/2010-July/044176.html

One of the causes could be side effect of atleast one more bug related to
pthreads and static link which has now been fixed.
http://lists.uclibc.org/pipermail/uclibc/2013-October/047958.html

I have solved this w/o looking at other pacthes but would like to give
credit to Peter and others for confirming that it makes sense.

ldso: fix standalone execution on x86_64 architecture

If the dynamic linker is built with LDSO_STANDALONE_SUPPORT=y, it can
load then run a dynamically linked program when explicitly invoked
from the command line.  This is used for test and prelink purposes,

This feature is currently broken on x86_64 since the number of command
line arguments (ie. argc) passed from the kernel is an "elf_addr_t"
(64 bit on x86_64), whereas it is read as an "unsigned int" (32 bit on
