(1 to 1 mapping) * - The correct granularity of an OpenOwner is not nearly so * obvious. An OpenOwner does the following: * - provides a serial sequencing of Open/Close/Lock-with-new-lockowner * - is used to check for Open/Share contention (not applicable to * this client, since all Opens are Deny_None) * As such, I considered both extreme. * 1 OpenOwner per ClientID - Simple to manage, but fully serializes * all Open, Close and Lock (with a new lockowner) Ops. * 1 OpenOwner for each Open - This one results in an OpenConfirm for * every Open, for most servers. * So, I chose to use the same mapping as I did for LockOwnwers. * The main concern here is that you can end up with multiple Opens * for the same File Handle, but on different OpenOwners (opens * inherited from parents, grandparents...) and you do not know * which of these the vnodeop close applies to. This is handled by * delaying the Close Op(s) until all of the Opens have been closed. * (It is not yet obvious if this is the correct granularity.) * - How the code handles serialization: * - For the ClientId, it uses an exclusive lock while getting its * SetClientId and during recovery. Otherwise, it uses a shared * lock via a reference count. * - For the rest of the data structures, it uses an SMP mutex * (once the nfs client is SMP safe) and doesn't sleep while * manipulating the linked lists. * - The serialization of Open/Close/Lock/LockU falls out in the * "wash", since OpenOwners and LockOwners are both mapped from * Posix pid. In other words, there is only one Posix pid using * any given owner, so that owner is serialized. (If you change * the granularity of the OpenOwner, then code must be added to * serialize Ops on the OpenOwner.) * - When to get rid of OpenOwners and LockOwners. * - The function nfscl_cleanup_common() is executed after a process exits. * It goes through the client list looking for all Open and Lock Owners. * When one is found, it is marked "defunct" or in the case of * an OpenOwner without any Opens, freed. * The renew thread scans for defunct Owners and gets rid of them, * if it can. The LockOwners will also be deleted when the * associated Open is closed. * - If the LockU or Close Op(s) fail during close in a way * that could be recovered upon retry, they are relinked to the * ClientId's defunct open list and retried by the renew thread * until they succeed or an unmount/recovery occurs. * (Since we are done with them, they do not need to be recovered.) */ #ifndef APPLEKEXT #include /* * Global variables */ extern struct nfsstats newnfsstats; extern struct nfsreqhead nfsd_reqq; +extern u_int32_t newnfs_false, newnfs_true; NFSREQSPINLOCK; NFSCLSTATEMUTEX; int nfscl_inited = 0; struct nfsclhead nfsclhead; /* Head of clientid list */ int nfscl_deleghighwater = NFSCLDELEGHIGHWATER; #endif /* !APPLEKEXT */ static int nfscl_delegcnt = 0; static int nfscl_getopen(struct nfsclownerhead *, u_int8_t *, int, u_int8_t *, u_int8_t *, u_int32_t, struct nfscllockowner **, struct nfsclopen **); static void nfscl_clrelease(struct nfsclclient *); static void nfscl_cleanclient(struct nfsclclient *); static void nfscl_expireclient(struct nfsclclient *, struct nfsmount *, struct ucred *, NFSPROC_T *); static int nfscl_expireopen(struct nfsclclient *, struct nfsclopen *, struct nfsmount *, struct ucred *, NFSPROC_T *); static void nfscl_recover(struct nfsclclient *, struct ucred *, NFSPROC_T *); static void nfscl_insertlock(struct nfscllockowner *, struct nfscllock *, struct nfscllock *, int); static int nfscl_updatelock(struct nfscllockowner *, struct nfscllock **, struct nfscllock **, int); static void nfscl_delegreturnall(struct nfsclclient *, NFSPROC_T *); static u_int32_t nfscl_nextcbident(void); -static mount_t nfscl_getmnt(u_int32_t); +static mount_t nfscl_getmnt(int, uint8_t *, u_int32_t, struct nfsclclient **); +static struct nfsclclient *nfscl_getclnt(u_int32_t); +static struct nfsclclient *nfscl_getclntsess(uint8_t *); static struct nfscldeleg *nfscl_finddeleg(struct nfsclclient *, u_int8_t *, int); static int nfscl_checkconflict(struct nfscllockownerhead *, struct nfscllock *, u_int8_t *, struct nfscllock **); static void nfscl_freealllocks(struct nfscllockownerhead *, int); static int nfscl_localconflict(struct nfsclclient *, u_int8_t *, int, struct nfscllock *, u_int8_t *, struct nfscldeleg *, struct nfscllock **); static void nfscl_newopen(struct nfsclclient *, struct nfscldeleg *, struct nfsclowner **, struct nfsclowner **, struct nfsclopen **, struct nfsclopen **, u_int8_t *, u_int8_t *, int, int *); static int nfscl_moveopen(vnode_t , struct nfsclclient *, struct nfsmount *, struct nfsclopen *, struct nfsclowner *, struct nfscldeleg *, struct ucred *, NFSPROC_T *); static void nfscl_totalrecall(struct nfsclclient *); static int nfscl_relock(vnode_t , struct nfsclclient *, struct nfsmount *, struct nfscllockowner *, struct nfscllock *, struct ucred *, NFSPROC_T *); static int nfscl_tryopen(struct nfsmount *, vnode_t , u_int8_t *, int, u_int8_t *, int, u_int32_t, struct nfsclopen *, u_int8_t *, int, struct nfscldeleg **, int, u_int32_t, struct ucred *, NFSPROC_T *); static int nfscl_trylock(struct nfsmount *, vnode_t , u_int8_t *, int, struct nfscllockowner *, int, int, u_int64_t, u_int64_t, short, struct ucred *, NFSPROC_T *); static int nfsrpc_reopen(struct nfsmount *, u_int8_t *, int, u_int32_t, struct nfsclopen *, struct nfscldeleg **, struct ucred *, NFSPROC_T *); static void nfscl_freedeleg(struct nfscldeleghead *, struct nfscldeleg *); static int nfscl_errmap(struct nfsrv_descript *); static void nfscl_cleanup_common(struct nfsclclient *, u_int8_t *); static int nfscl_recalldeleg(struct nfsclclient *, struct nfsmount *, struct nfscldeleg *, vnode_t, struct ucred *, NFSPROC_T *, int); static void nfscl_freeopenowner(struct nfsclowner *, int); static void nfscl_cleandeleg(struct nfscldeleg *); static int nfscl_trydelegreturn(struct nfscldeleg *, struct ucred *, struct nfsmount *, NFSPROC_T *); static void nfscl_emptylockowner(struct nfscllockowner *, struct nfscllockownerfhhead *); static short nfscberr_null[] = { 0, 0, }; static short nfscberr_getattr[] = { NFSERR_RESOURCE, NFSERR_BADHANDLE, NFSERR_BADXDR, NFSERR_RESOURCE, NFSERR_SERVERFAULT, 0, }; static short nfscberr_recall[] = { NFSERR_RESOURCE, NFSERR_BADHANDLE, NFSERR_BADSTATEID, NFSERR_BADXDR, NFSERR_RESOURCE, NFSERR_SERVERFAULT, 0, }; static short *nfscl_cberrmap[] = { nfscberr_null, nfscberr_null, nfscberr_null, nfscberr_getattr, nfscberr_recall }; #define NETFAMILY(clp) \ (((clp)->nfsc_flags & NFSCLFLAGS_AFINET6) ?
