1297c478bd9Sstevel@tonic-gate  *
1307c478bd9Sstevel@tonic-gate  * Each process has a list of open files, fi_list, indexed by fd.
1317c478bd9Sstevel@tonic-gate  * fi_list is an array of uf_entry_t structures, each with its own lock.
1327c478bd9Sstevel@tonic-gate  * One might think that the correct way to lock a file descriptor would be:
1337c478bd9Sstevel@tonic-gate  *
1347c478bd9Sstevel@tonic-gate  *	ufp = fip->fi_list[fd];
1357c478bd9Sstevel@tonic-gate  *	mutex_enter(&ufp->uf_lock);
1367c478bd9Sstevel@tonic-gate  *
1377c478bd9Sstevel@tonic-gate  * However, that construct is only safe if fi_lock is already held.  If not,
1387c478bd9Sstevel@tonic-gate  * fi_list can change in the window between loading ufp and entering uf_lock.
1397c478bd9Sstevel@tonic-gate  * The UF_ENTER() macro deals with this possibility.  UF_ENTER(ufp, fip, fd)
1407c478bd9Sstevel@tonic-gate  * locks fd and sets ufp to fd's uf_entry.  The locking rules are as follows:
1417c478bd9Sstevel@tonic-gate  *
1427c478bd9Sstevel@tonic-gate  * (1) fi_lock protects fi_list and fi_nfiles.  It also protects the
1437c478bd9Sstevel@tonic-gate  *     uf_alloc and uf_busy fields of every fd's ufp; see fd_find() for
1447c478bd9Sstevel@tonic-gate  *     details on file descriptor allocation.
1457c478bd9Sstevel@tonic-gate  *
1467c478bd9Sstevel@tonic-gate  * (2) UF_ENTER(ufp, fip, fd) locks descriptor fd and sets ufp to point
1477c478bd9Sstevel@tonic-gate  *     to the uf_entry_t for fd.  UF_ENTER() protects all fields in ufp
1487c478bd9Sstevel@tonic-gate  *     except uf_alloc and uf_busy.  UF_ENTER(ufp, fip, fd) also prevents
1497c478bd9Sstevel@tonic-gate  *     ufp->uf_alloc, ufp->uf_busy, fip->fi_list and fip->fi_nfiles from
1507c478bd9Sstevel@tonic-gate  *     changing.
1517c478bd9Sstevel@tonic-gate  *
1527c478bd9Sstevel@tonic-gate  * (3) The lock ordering is (1), (2).
1537c478bd9Sstevel@tonic-gate  *
1547c478bd9Sstevel@tonic-gate  * (4) Note that fip->fi_list and fip->fi_nfiles cannot change while *any*
1557c478bd9Sstevel@tonic-gate  *     file list lock is held.  Thus flist_grow() must acquire all such
1567c478bd9Sstevel@tonic-gate  *     locks -- fi_lock and every fd's uf_lock -- to install a new file list.

2617c478bd9Sstevel@tonic-gate  * Here, we define a fake version of struct user for programs
2627c478bd9Sstevel@tonic-gate  * (debuggers) that use ptrace() to read and modify the saved
2637c478bd9Sstevel@tonic-gate  * registers directly in the u-area.  ptrace() has been removed
2647c478bd9Sstevel@tonic-gate  * from the operating system and now exists as a library function
2657c478bd9Sstevel@tonic-gate  * in libc, built on the /proc process filesystem.  The ptrace()
2667c478bd9Sstevel@tonic-gate  * library function provides access only to the members of the
2677c478bd9Sstevel@tonic-gate  * fake struct user defined here.
2687c478bd9Sstevel@tonic-gate  *
2697c478bd9Sstevel@tonic-gate  * User-level programs that must know the real contents of struct
2707c478bd9Sstevel@tonic-gate  * user will have to define _KMEMUSER before including <sys/user.h>.
2717c478bd9Sstevel@tonic-gate  * Such programs also become machine specific. Carefully consider
2727c478bd9Sstevel@tonic-gate  * the consequences of your actions.
