From 34b8c6a4409682b1153fbd6a38ebe68a3d107a92 Mon Sep 17 00:00:00 2001 From: csjp Date: Sat, 28 Jan 2006 19:24:40 +0000 Subject: Manage the ucred for the NFS server using the crget/crfree API defined in kern_prot.c. This API handles reference counting among many other things. Notably, if MAC is compiled into the kernel, it will properly initialize the MAC labels when the ucred is allocated. This work is in preparation for a new MAC entry point which will be responsible for properly initializing policy specific labels for the NFS server credential. Utilization of the crfree/crget APIs reduce the complexity associated with this label's management. Submitted by: green (with changes) [1] Obtained from: TrustedBSD Project Discussed with: rwatson, alfred [1] I moved the ucred allocation outside the scope of the NFS server lock to prevent M_WAIKOK allocations from occurring with non-sleep-able locks held. Additionally, to reduce complexity, the ucred persist as long as the NFS server descriptor. --- sys/nfsserver/nfs.h | 2 +- 1 file changed, 1 insertion(+), 1 deletion(-) (limited to 'sys/nfsserver/nfs.h') diff --git a/sys/nfsserver/nfs.h b/sys/nfsserver/nfs.h index e8d5d21..809df66 100644 --- a/sys/nfsserver/nfs.h +++ b/sys/nfsserver/nfs.h @@ -258,7 +258,7 @@ struct nfsrv_descript { u_int32_t nd_retxid; /* Reply xid */ struct timeval nd_starttime; /* Time RPC initiated */ fhandle_t nd_fh; /* File handle */ - struct ucred nd_cr; /* Credentials */ + struct ucred *nd_cr; /* Credentials */ }; /* Bits for "nd_flag" */ -- cgit v1.1
