Fw: [Bugme-new] [Bug 7179] New: Compilation of .tmp_linux1 fails due to missing declaration in net/netfilter/xt_physdev.c

[Andrew Morton <akpm@osdl.org>]

Methinks CONFIG_NETFILTER_XT_TARGET_CLASSIFY should depend upon
CONFIG_BRIDGE_NETFILTER.  Because brnf_deferred_hooks is defined in
net/bridge/br_netfilter.c and is referred to in net/netfilter/xt_physdev.c.

Or something else ;)

           Summary: Compilation of .tmp_linux1 fails due to missing
                    declaration in net/netfilter/xt_physdev.c
    Kernel Version: 2.6.18
            Status: NEW
          Severity: high
             Owner: laforge@gnumonks.org
         Submitter: gfrank@neoservers.com


Most recent kernel where this bug did not occur: 2.6.17.13
Distribution: CentOS
Hardware Environment: Dual Intel Xeon 5160
Software Environment: gcc 3.4.6, glibc 2.3.4, make 3.8
Problem Description:

Using the same config from 2.6.17.13, kernel 2.6.18 fails on make when 
attempting to make .tmp_vmlinux1

LD      .tmp_vmlinux1
net/built-in.o(.text.checkentry+0x1e1): In function `checkentry':
net/netfilter/xt_physdev.c:130: undefined reference to `brnf_deferred_hooks'
make: *** [.tmp_vmlinux1] Error 1

Line 130 is simply "brnf_deferred_hooks = 1;"  This variable is also used on 
line 118.

Adding 

"int brnf_deferred_hooks = 0;" 

in a line before line 104 (static int) will cause .tmp_vmlinux1 to be 
successfully created, and make will finish successfully.  However, it will 
generate a warning (seen below) on now line 119 which can be fixed by changing 
it to: 

"if ((brnf_deferred_hooks == 0) & (info->bitmask & XT_PHYSDEV_OP_OUT) && "

The warning generated is:

net/netfilter/xt_physdev.c: In function `checkentry':
net/netfilter/xt_physdev.c:118: warning: ISO C90 forbids mixed declarations 
and code

The kernel produced after making these changes works fine

Steps to reproduce:

I am unsure of which kernel .config parameter is sparking this.  My .config 
can be found here: http://www.animeforum.com/jakiao/misato.config
