2.6.23 alpha unistd.h changes

[Oliver Falk]

Hi!

At Alphacore we used to patch the kernel headers for a while now; We
added syscalls __NR_openat (447) until __NR_tee (466).

However, since 2.6.23 these syscall where added upstream, but with
different syscall numbers; What happens is the following:

* glibc 2.6.90 compiled with 2.6.23 headers installed
* kernel 2.6.21 (our patched headers in place, different syscall
'ordering'/numbers) installed

[root@tyskie ~]# uname -r; touch x; rm -f x
2.6.23-0.145.rc4.fc8
rm: cannot remove `x': File exists

:-( I don't want to live without rm :-P and chmod doesn't work as well...

If I start 2.6.15, where these syscalls where not in place, it works
just fine. If I install old glibc 2.6 (compiled against 2.6.21 headers)
and kernel 2.6.21 also everything is fine.

Final test was now:
* Boot kernel 2.6.23 and glibc 2.6.90 (compiled against 2.6.23 headers),
also everything seems to work.

As these additions are quite new to upstream kernel, but at Alphacore we
have patched it since a while now (I don't know about other Alpha ports;
Debian folks may speak up now!), I would suggest to use the same
'ordering' of the syscalls upstream and add the new syscalls that we had
not in place, but are now upstream to the end of our 'old' list.

I have attached our patch that we used for 2.6.21.


Please let me know if that's fine everyone and keep me posted directly
and only via m/l, as I might miss the mail then...

Best,
 Oliver
