2.4.0-test9 + LFS

2.4.0-test9 + LFS

[Wakko Warner]

I attempted to create a 4gb sparce file with dd.  It failed.
I created one that was 2.1gb in size which worked.  Then I appeneded more
junk to the end of the file making it over 2.2gb.

doing an ls -l shows:
ls: x: Value too large for defined data type

NOTE: this worked in 2.4.0-test6 and I believe it stopped working around
test8, but I'm not sure.  May have been around test7.

Previous kernels allowed up to 4gb to be returned by the old stat.
Upgrade your glibc and fileutils -- most recent distributions (Red Hat,
SuSE, ...) are LFS ready, and the only reports I've seen about this
concerned Slackware.

	Your userspace tools are not using LFS compliant
	open(O_LARGEFILE), and stat64()  methods.

	EXT2 got corrected to do LFS limited open() handling
	at correct limit (2G-1) at around that time.

	There still lurks some mis-compliance issues at
	read() and write() which are still allowed to
	go over 2G-1 marker without the fd having
	O_LARGEFILE flag.

I did upgrade that and it didn't help anything.

Was your glibc compiled against 2.4 kernel headers?

And Debian :-( It is hard to get rid of such file - GNU 'rm' complains
too, as it tries to stat that file first :-( Fortunately

echo -n > x; rm x

works. I filled bugreport some time ago (when 2.1.94 come to woody), but 
it was closed, as there are no 2.4.x headers in Debian, so it is not 
possible to recompile glibc against them... Recompiling glibc is enough 
for woody, BTW.

Then it's compiled against the v2.2 kernel headers.

That I do not know.  it's v 2.1.99  that came with debian in the past week
or so

That explains why LFS isn't working then.  I strongly suggest that the
Debian glibc maintainers compile against 2.4 kernel headers or patch their
2.2 kernel headers to include the LFS stubs.
