The host adapters are listed in the ISA and PCI # device configuration sections below. # # It is possible to wire down your SCSI devices so that a given bus, # target, and LUN always come on line as the same device unit. In # earlier versions the unit numbers were assigned in the order that # the devices were probed on the SCSI bus. This means that if you # removed a disk drive, you may have had to rewrite your /etc/fstab # file, and also that you had to be careful when adding a new disk # as it may have been probed earlier and moved your device configuration # around. (See also option GEOM_VOL for a different solution to this # problem.) # This old behavior is maintained as the default behavior. The unit # assignment begins with the first non-wired down unit for a device # type. For example, if you wire a disk as "da3" then the first # non-wired disk will be assigned da4. # The syntax for wiring down devices is: hint.scbus.0.at="ahc0" hint.scbus.1.at="ahc1" hint.scbus.1.bus="0" hint.scbus.3.at="ahc2" hint.scbus.3.bus="0" hint.scbus.2.at="ahc2" hint.scbus.2.bus="1" hint.da.0.at="scbus0" hint.da.0.target="0" hint.da.0.unit="0" hint.da.1.at="scbus3" hint.da.1.target="1" hint.da.2.at="scbus2" hint.da.2.target="3" hint.sa.1.at="scbus1" hint.sa.1.target="6" # "units" (SCSI logical unit number) that are not specified are # treated as if specified as LUN 0. # All SCSI devices allocate as many units as are required. # The ch driver drives SCSI Media Changer ("jukebox") devices. # # The da driver drives SCSI Direct Access ("disk") and Optical Media # ("WORM") devices. # # The sa driver drives SCSI Sequential Access ("tape") devices. # # The cd driver drives SCSI Read Only Direct Access ("cd") devices. # # The ses driver drives SCSI Environment Services ("ses") and # SAF-TE ("SCSI Accessible Fault-Tolerant Enclosure") devices. # # The pt driver drives SCSI Processor devices. # # The sg driver provides a passthrough API that is compatible with the # Linux SG driver.

It can also stand on its own and provide # source level API compatibility for porting apps to FreeBSD. # # Target Mode support is provided here but also requires that a SIM # (SCSI Host Adapter Driver) provide support as well. # # The targ driver provides target mode support as a Processor type device. # It exists to give the minimal context necessary to respond to Inquiry # commands.

$FreeBSD$ # # On the handling of kernel options # # All kernel options should be listed in NOTES, with suitable # descriptions. Negative options (options that make some code not # compile) should be commented out; LINT (generated from NOTES) should # compile as much code as possible. Try to structure option-using # code so that a single option only switch code on, or only switch # code off, to make it possible to have a full compile-test. If # necessary, you can check for COMPILING_LINT to get maximum code # coverage. # # All new options shall also be listed in either "conf/options" or # "conf/options.".

Socket layer private. * * sodealloc() tears down socket layer state for a socket, called only by * sofree() and sonewconn(). Socket layer private. * * pru_attach() associates protocol layer state with an allocated socket; * called only once, may fail, aborting socket allocation. This is called * from socreate() and sonewconn(). Socket layer private. * * pru_detach() disassociates protocol layer state from an attached socket, * and will be called exactly once for sockets in which pru_attach() has * been successfully called. If pru_attach() returned an error, * pru_detach() will not be called. Socket layer private. * * pru_abort() and pru_close() notify the protocol layer that the last * consumer of a socket is starting to tear down the socket, and that the * protocol should terminate the connection. Historically, pru_abort() also * detached protocol state from the socket state, but this is no longer the * case. * * socreate() creates a socket and attaches protocol state. This is a public * interface that may be used by socket layer consumers to create new * sockets. * * sonewconn() creates a socket and attaches protocol state. This is a * public interface that may be used by protocols to create new sockets when * a new connection is received and will be available for accept() on a * listen socket. * * soclose() destroys a socket after possibly waiting for it to disconnect. * This is a public interface that socket consumers should use to close and * release a socket when done with it. * * soabort() destroys a socket without waiting for it to disconnect (used * only for incoming connections that are already partially or fully * connected). This is used internally by the socket layer when clearing * listen socket queues (due to overflow or close on the listen socket), but * is also a public interface protocols may use to abort connections in * their incomplete listen queues should they no longer be required. Sockets * placed in completed connection listen queues should not be aborted for * reasons described in the comment above the soclose() implementation. This * is not a general purpose close routine, and except in the specific * circumstances described here, should not be used. * * sofree() will free a socket and its protocol state if all references on * the socket have been released, and is the public interface to attempt to * free a socket when a reference is removed. This is a socket layer private * interface. * * NOTE: In addition to socreate() and soclose(), which provide a single * socket reference to the consumer to be managed as required, there are two * calls to explicitly manage socket references, soref(), and sorele(). * Currently, these are generally required only when transitioning a socket * from a listen queue to a file descriptor, in order to prevent garbage * collection of the socket at an untimely moment. For a number of reasons, * these interfaces are not preferred, and should be avoided. * * NOTE: With regard to VNETs the general rule is that callers do not set * curvnet. Exceptions to this rule include soabort(), sodisconnect(), * sofree() (and with that sorele(), sotryfree()), as well as sonewconn() * and sorflush(), which are usually called from a pre-set VNET context. * sopoll() currently does not need a VNET context to be set. */ #include __FBSDID("$FreeBSD$"); #include "opt_inet.h" #include "opt_inet6.h" #include "opt_compat.h" #include #include #include #include #include #include #include #include #include #include #include /* for struct knote */ #include #include #include #include #include #include #include #include #include #include #include #include #include #include #include #include +#include #include #include #include #include #include #include #include #ifdef COMPAT_FREEBSD32 #include #include #include #endif static int soreceive_rcvoob(struct socket *so, struct uio *uio, int flags); static void filt_sordetach(struct knote *kn); static int filt_soread(struct knote *kn, long hint); static void filt_sowdetach(struct knote *kn); static int filt_sowrite(struct knote *kn, long hint); static int filt_solisten(struct knote *kn, long hint); static int inline hhook_run_socket(struct socket *so, void *hctx, int32_t h_id); fo_kqfilter_t soo_kqfilter; static struct filterops solisten_filtops = { .f_isfd = 1, .f_detach = filt_sordetach, .f_event = filt_solisten, }; static struct filterops soread_filtops = { .f_isfd = 1, .f_detach = filt_sordetach, .f_event = filt_soread, }; static struct filterops sowrite_filtops = { .f_isfd = 1, .f_detach = filt_sowdetach, .f_event = filt_sowrite, }; so_gen_t so_gencnt; /* generation count for sockets */ MALLOC_DEFINE(M_SONAME, "soname", "socket name"); MALLOC_DEFINE(M_PCB, "pcb", "protocol control block"); #define VNET_SO_ASSERT(so) \ VNET_ASSERT(curvnet != NULL, \ ("%s:%d curvnet is NULL, so=%p", __func__, __LINE__, (so))); VNET_DEFINE(struct hhook_head *, socket_hhh[HHOOK_SOCKET_LAST + 1]); #define V_socket_hhh VNET(socket_hhh) /* * Limit on the number of connections in the listen queue waiting * for accept(2). * NB: The orginal sysctl somaxconn is still available but hidden * to prevent confusion about the actual purpose of this number. */ static u_int somaxconn = SOMAXCONN; static int sysctl_somaxconn(SYSCTL_HANDLER_ARGS) { int error; int val; val = somaxconn; error = sysctl_handle_int(oidp, &val, 0, req); if (error || !req->newptr ) return (error); /* * The purpose of the UINT_MAX / 3 limit, is so that the formula * 3 * so_qlimit / 2 * below, will not overflow. */ if (val < 1 || val > UINT_MAX / 3) return (EINVAL); somaxconn = val; return (0); } SYSCTL_PROC(_kern_ipc, OID_AUTO, soacceptqueue, CTLTYPE_UINT | CTLFLAG_RW, 0, sizeof(int), sysctl_somaxconn, "I", "Maximum listen socket pending connection accept queue size"); SYSCTL_PROC(_kern_ipc, KIPC_SOMAXCONN, somaxconn, CTLTYPE_UINT | CTLFLAG_RW | CTLFLAG_SKIP, 0, sizeof(int), sysctl_somaxconn, "I", "Maximum listen socket pending connection accept queue size (compat)"); static int numopensockets; SYSCTL_INT(_kern_ipc, OID_AUTO, numopensockets, CTLFLAG_RD, &numopensockets, 0, "Number of open sockets"); /* * accept_mtx locks down per-socket fields relating to accept queues.
