This 1232eae72b5bSSebastien Roy * function handles all ioctls on behalf of modules listed in 1233eae72b5bSSebastien Roy * dld_ioc_modtable. 1234eae72b5bSSebastien Roy * 1235eae72b5bSSebastien Roy * When an ioctl is received, this function looks for the associated 1236eae72b5bSSebastien Roy * module-id-specific ioctl information using dld_ioc_findmod(). The 1237eae72b5bSSebastien Roy * call to ddi_hold_devi_by_instance() on the associated device will 1238eae72b5bSSebastien Roy * cause the kernel module responsible for the ioctl to be loaded if 1239eae72b5bSSebastien Roy * it's not already loaded, which should result in that module calling 1240eae72b5bSSebastien Roy * dld_ioc_register(), thereby filling in the dim_list containing the 1241eae72b5bSSebastien Roy * details for the ioctl being processed. 1242eae72b5bSSebastien Roy * 1243eae72b5bSSebastien Roy * This function can then perform operations such as copyin() data and 1244eae72b5bSSebastien Roy * do credential checks based on the registered ioctl information, 1245eae72b5bSSebastien Roy * then issue the callback function di_func() registered by the 1246eae72b5bSSebastien Roy * responsible module. Upon return, the appropriate copyout() 1247eae72b5bSSebastien Roy * operation can be performed and the operation completes. 1248eae72b5bSSebastien Roy */ 1249eae72b5bSSebastien Roy /* ARGSUSED */ 1250eae72b5bSSebastien Roy static int 1251eae72b5bSSebastien Roy drv_ioctl(dev_t dev, int cmd, intptr_t arg, int mode, cred_t *cred, int *rvalp) 1252eae72b5bSSebastien Roy { 1253eae72b5bSSebastien Roy dld_ioc_modentry_t *dim; 1254eae72b5bSSebastien Roy dld_ioc_info_t *info; 1255eae72b5bSSebastien Roy dev_info_t *dip = NULL; 1256eae72b5bSSebastien Roy void *buf = NULL; 1257eae72b5bSSebastien Roy size_t sz; 1258eae72b5bSSebastien Roy int i, err; 1259eae72b5bSSebastien Roy 1260eae72b5bSSebastien Roy if ((dim = dld_ioc_findmod(DLD_IOC_MODID(cmd))) == NULL) 1261eae72b5bSSebastien Roy return (ENOTSUP); 1262eae72b5bSSebastien Roy 1263eae72b5bSSebastien Roy dip = ddi_hold_devi_by_instance(ddi_name_to_major(dim->dim_modname), 1264eae72b5bSSebastien Roy 0, 0); 1265eae72b5bSSebastien Roy if (dip == NULL || dim->dim_list == NULL) { 1266eae72b5bSSebastien Roy err = ENODEV; 1267eae72b5bSSebastien Roy goto done; 1268eae72b5bSSebastien Roy } 1269eae72b5bSSebastien Roy 1270eae72b5bSSebastien Roy for (i = 0; i < dim->dim_count; i++) { 1271eae72b5bSSebastien Roy if (cmd == dim->dim_list[i].di_cmd) 1272eae72b5bSSebastien Roy break; 1273eae72b5bSSebastien Roy } 1274eae72b5bSSebastien Roy if (i == dim->dim_count) { 1275eae72b5bSSebastien Roy err = ENOTSUP; 1276eae72b5bSSebastien Roy goto done; 1277eae72b5bSSebastien Roy } 1278eae72b5bSSebastien Roy 1279eae72b5bSSebastien Roy info = &dim->dim_list[i]; 1280da14cebeSEric Cheng if ((err = drv_check_policy(info, cred)) != 0) 1281eae72b5bSSebastien Roy goto done; 1282eae72b5bSSebastien Roy 1283eae72b5bSSebastien Roy sz = info->di_argsize; 1284eae72b5bSSebastien Roy if ((buf = kmem_zalloc(sz, KM_NOSLEEP)) == NULL) { 1285eae72b5bSSebastien Roy err = ENOMEM; 1286eae72b5bSSebastien Roy goto done; 1287eae72b5bSSebastien Roy } 1288eae72b5bSSebastien Roy 1289eae72b5bSSebastien Roy if ((info->di_flags & DLDCOPYIN) && 1290eae72b5bSSebastien Roy ddi_copyin((void *)arg, buf, sz, mode) != 0) { 1291eae72b5bSSebastien Roy err = EFAULT; 1292eae72b5bSSebastien Roy goto done; 1293eae72b5bSSebastien Roy } 1294eae72b5bSSebastien Roy 1295da14cebeSEric Cheng err = info->di_func(buf, arg, mode, cred, rvalp); 1296eae72b5bSSebastien Roy 1297eae72b5bSSebastien Roy if ((info->di_flags & DLDCOPYOUT) && 1298eae72b5bSSebastien Roy ddi_copyout(buf, (void *)arg, sz, mode) != 0 && err == 0) 1299eae72b5bSSebastien Roy err = EFAULT; 1300eae72b5bSSebastien Roy 1301eae72b5bSSebastien Roy done: 1302eae72b5bSSebastien Roy if (buf != NULL) 1303eae72b5bSSebastien Roy kmem_free(buf, sz); 1304eae72b5bSSebastien Roy if (dip != NULL) 1305eae72b5bSSebastien Roy ddi_release_devi(dip); 1306eae72b5bSSebastien Roy return (err); 13070ba2cbe9Sxc } 1308
