Description Steve Snyder 2008-06-23 20:29:41 UTC
Description of problem:

Function xfrm_audit_state_replay(a, b, c) in ~/include/net/xfrm.h is replaced bu
a macro of the same name if the Auditd System Calls feature is not enabled.  The
probalem is that the macro is defined as having 4, not 3, parameters.  The code
that invokes this func/macro only provides 3 parameters.

Version-Release number of selected component (if applicable):

Kernel 2.6.18-92.el5.i686

How reproducible:


Steps to Reproduce:
1. Disable the Auditd System Calls feature in the kernel
2.  Attempt to rebuild the kernel
Actual results:

  CC      net/ipv4/xfrm4_input.o
net/ipv4/xfrm4_input.c:98:39: error: macro "xfrm_audit_state_replay" requires 4
arguments, but only 3 given
net/ipv4/xfrm4_input.c: In function ‘xfrm4_rcv_encap’:
net/ipv4/xfrm4_input.c:98: error: ‘xfrm_audit_state_replay’ undeclared (first
use in this function)
net/ipv4/xfrm4_input.c:98: error: (Each undeclared identifier is reported only once
net/ipv4/xfrm4_input.c:98: error: for each function it appears in.)
make[2]: *** [net/ipv4/xfrm4_input.o] Error 1
make[1]: *** [net/ipv4] Error 2
make: *** [net] Error 2

Expected results:

Placeholder macro should be defined as having the same number of parameters as
the function it is replacing.

Additional info:

Same param count mismatch is also seen with function/macro
xfrm_naudit_state_replay() in same header file.

Change 4-param macros to match 3-param functions

Comment 2 Prarit Bhargava 2008-06-24 14:47:59 UTC
Red Hat does not support custom kernel building.  However, custom kernels should
still build :)

Thanks Steve -- I'll see what I can do about getting this into 5.3.

RHEL5 fix for this issue

Loosely based on original patch -- now fixes compile errors and warning.
