Description Alexander Kourakos 2000-10-13 18:37:39 UTC

If the kernel is compiled with
CONFIG_IP_MASQUERADE and without 
CONFIG_IP_MASQUERADE_MOD, it will fail with errors referring to 
'ip_masq_hash' and 'ip_masq_unhash'.

The fix I used is either to configure for both MASQUERADE and 
MASQUERADE_MOD, or add these lines near the end of 
<linux/ip_masq.h>:

extern int ip_masq_hash(struct ip_masq *);
extern int ip_masq_unhash(struct ip_masq *);

I believe that this is the same bug as #18706

Comment 1 Alexander Kourakos 2000-10-13 18:54:26 UTC

why does Bugzilla say "Red Hat Linux - 7.07.0"?

Tryed the first solution (both MASQUERADE and MASQUERADE_MOD) did not work...

Comment 5 Need Real Name 2000-11-22 23:47:21 UTC

Ok! Got it right this time. The solution with CONFIG_MASQUERADE=y and 
CONFIG_MASQUERADE_MOD=y does work!
Note that to have CONFIG_MASQUERADE_MOD available you must enable experimental 
modules...

Someone else suggested another solution in google's usenet search site.  Here
is the text:

The problem is that the two symbols are defined in ip_masq_mod.h
which is only included if you make IP_MASQUERADING as a module.
Edit the file ./net/ipv4/ip_masq.c and add two lines:

int ip_masq_hash(struct ip_masq *ms);
int ip_masq_unhash(struct ip_masq *ms);

Put these after the #includes but before the EXPORT_SYMBOLs

After I did this, the kernel built and ran fine.
