Subject: Re: [PATCH 1/4] security: filesystem capabilities bugfix1

I'll assume that patches 1 and 2 are needed in 2.6.26 and that
patches 3 and 4 are for 2.6.27.

Patches 1 and/or 2 caused a reject in
security-protect-legacy-applications-from-executing-with-insufficient-privilege.patch:

***************
*** 350,357 ****
  				bprm->e_gid = current->gid;
  			}
  			if (!capable (CAP_SETPCAP)) {
- 				new_permitted = cap_intersect (new_permitted,
- 							current->cap_permitted);
  			}
  		}
  	}
--- 364,372 ----
  				bprm->e_gid = current->gid;
  			}
  			if (!capable (CAP_SETPCAP)) {
+ 				bprm->cap_post_exec_permitted = cap_intersect(
+ 					bprm->cap_post_exec_permitted,
+ 					current->cap_permitted);
  			}
  		}
  	}

which looked simple to fix.  I'll resend the resulting diff - please
check.
