Clone corruption to G4 MacOSX

Clone corruption to G4 MacOSX

[Perry Wagle]

I have a G4 iBook running MacOSX 10.4.10.  If I build the most recent  
production git (git-1.5.3.2) from the tarball from the git website, I  
get a corrupt copy of Linus's kernel repository (git://git.kernel.org/ 
pub/scm/linux/kernel/git/torvalds/linux-2.6.git) when I try to clone  
it.  Specifically, my copy is missing several files, including ./ 
include/linux/netfilter/xt_CONNMARK.h.  The involved files seem to be:

include/linux/netfilter/xt_CONNMARK.h
include/linux/netfilter/xt_DSCP.h
include/linux/netfilter/xt_MARK.h
include/linux/netfilter/xt_TCPMSS.h
include/linux/netfilter_ipv4/ipt_CONNMARK.h
include/linux/netfilter_ipv4/ipt_DSCP.h
include/linux/netfilter_ipv4/ipt_ECN.h
include/linux/netfilter_ipv4/ipt_MARK.h
include/linux/netfilter_ipv4/ipt_TCPMSS.h
include/linux/netfilter_ipv4/ipt_TOS.h
include/linux/netfilter_ipv4/ipt_TTL.h
include/linux/netfilter_ipv6/ip6t_HL.h
include/linux/netfilter_ipv6/ip6t_MARK.h
net/ipv4/netfilter/ipt_ECN.c
net/ipv4/netfilter/ipt_TOS.c
net/ipv4/netfilter/ipt_TTL.c
net/ipv6/netfilter/ip6t_HL.c
net/netfilter/xt_CONNMARK.c
net/netfilter/xt_DSCP.c
net/netfilter/xt_MARK.c
net/netfilter/xt_TCPMSS.c

I first noticed this corruption around August 14, 2007, when it  
seemed to be in the head of the clone of Linus's repository.  I was  
able to make it go away by committing the HEAD.  I was just starting  
with git, and figured I got some incomplete copy because Linus was in  
the middle of something.  Now I cannot find any commits for  
xt_CONNMARK.h or xt_connmark.h since 2006, especially around August  
14, but that might be my naivete.

If I clone Linus's repository to a x86 machine, I get no corruption.

My wild ass guess is that being big-endian is causing trouble.

The problem is MacOSX uses a case-insensitive filesystem by default...

Is the filesystem HFS+ that is case-losing?

Yeah, that'd be it.  Thanks!
