Fork

__data_start needs to be added to all crt0.S files that don't currently
have it. It is used by the boehm gc, amoung other things.

Kill off the now obsolete __libc_vfork symbol

This patch introduces optimized versions of memcpy and memset for

Thanks, this patch implements your suggestion.

A program that requests __pthread_sig_debug to be blocked will
self-deadlock when it requests a thread to be created, because the
debugger (rda or gdb) will never get the signal, so it won't wake up
the pthread manager as expected.

This patch fixes it.

update libdl so it also groks the new _dl_errno

Add define for SHM_HUGETLB

Oops, this adds the page alignment offset to the mprotected size.

Patch from Bradley D. LaRonde:
ld.so mprotect rwx .dyanmic segment for mips DT_DEBUG
Allow writing debug_addr into the .dynamic segment.
Even though the program header is marked RWE, the kernel
gives it to us rx.

Add a local '_dl_errno' to be used by syscalls in ldso, allowing
useful syscall failure diagnostics.

As noticed by the sharp eyed Joakim Tjernlund, I stupidly
hard coded 4096 instead of PAGE_SIZE. Because I'm an idiot.

Setup a _dl_pagesize value for use by staticly linked apps

make certain that getpagesize() returns correct the value for mips
by extracting the value from the ELF header.

Purge trailing white space

If I change that ELF_RTYPE_CLASS_COPY to ELF_RTYPE_CLASS_PLT to tell
_dl_find_hash to ignore stubs when resolving undefined functions without
stubs, the dlopen tests all pass. dlopen gets a pointer to the libc.so
malloc instead of a pointer to the libpthread malloc stub. Yay! :-)

Save r0 before modifying it.

Obligatory forgotten file...

Change clock() to allow wrapping.
Add timegm() function.
Make lookup_tzname() static (as it should have been).
Have strftime() get timezone information from the passed struct
for the %z and %Z conversions when using struct tm extensions.

Peter Mazinger asked for this several months ago.

Patch from Yoshinori Sato <ysato@users.sourceforge.jp>.

"Fix" this so that at least things will link when threading is disabled.
Also fix the sizeof() issue since the change to a dynamicly allocated buf.
Note! This is still broken wrt threading, but so is the glibc version.
I'm just commiting this for new until I can test my rewrite.

Fix a couple of issues in configurations I hadn't tested.

Add missing include.

UCLIBC_COMPLETELY_PIC does nothing, so kill it

Change the global 'buf' to 'servbuf' since some functions in here use
a local named 'buf' and we want to avoid shadowing that.

The vfork() wrapper defined in libpthread, that's used to run
pthread_atfork()-registered handlers, is not only a very bad idea,
it's broken and useless. Here's the rationale:

[---------snip----------]

Since the implementation as it stands is broken (linking a program
that vfork()s and exec()s on the child and wait()s on the parent works
unless you happen to link with libpthread), and I can't think of
any workable solution, I suggest that we simply remove the vfork()
overrider in the non-MMU case. Yes, we might lose some small amount
of functionality here, but it's not like people running uClinux expect
anything resembling actual fork() to work.

Fix screwed up formatting

Jeroen Dobbelaere writes:

Because variables are linked to fixed registers, there is a problem in :
(*__errno_location())=(-_r0);

As __errno_location() uses r0 to return the address of the errno location,
the negated address will be assigned instead of the error code.

Attached patch will resolve this.

Minor .deb updates

These headers should not be included in uClibc -- they should be
part of the ppp instead.
