* ACPI: remove acpi_device_uid() and related stuffBjorn Helgaas2009-09-25
| | | | | | | Nobody uses acpi_device_uid(), so this patch removes it. Signed-off-by: Bjorn Helgaas <bjorn.helgaas@hp.com> Signed-off-by: Len Brown <len.brown@intel.com>
* ACPI: remove acpi_device.flags.hardware_idBjorn Helgaas2009-09-25
| | | | | | | | | Every acpi_device has at least one ID (if there's no _HID or _CID, we give it a synthetic or default ID). So there's no longer a need to check whether an ID exists; we can just use it. Signed-off-by: Bjorn Helgaas <bjorn.helgaas@hp.com> Signed-off-by: Len Brown <len.brown@intel.com>
* ACPI: remove acpi_device.flags.compatible_idsBjorn Helgaas2009-09-25
| | | | | | | | We now keep a single list of IDs that includes both the _HID and any _CIDs. We no longer need to keep track of whether the device has a _CID. Signed-off-by: Bjorn Helgaas <bjorn.helgaas@hp.com> Signed-off-by: Len Brown <len.brown@intel.com>
* ACPI: maintain a single list of _HID and _CID IDsBjorn Helgaas2009-09-25
| | | | | | | | | | | There's no need to treat _HID and _CID differently. Keeping them in a single list makes code that uses the IDs a little simpler because it can just traverse the list rather than checking "do we have a HID?", "do we have any CIDs?"

* ACPI: make sure every acpi_device has an IDBjorn Helgaas2009-09-25
| | | | | | | | | | | | | | | | | This makes sure every acpi_device has at least one ID. If we build an acpi_device for a namespace node with no _HID or _CID, we sometimes synthesize an ID like "LNXCPU" or "LNXVIDEO". If we don't even have that, give it a default "device" ID. Note that this means things like: /sys/devices/LNXSYSTM:00/LNXSYBUS:00/HWP0001:00/HWP0002:04/device:00 (a PCI slot SxFy device) will have "hid" and "modprobe" entries, where they didn't before. These aren't very useful (a HID of "device" doesn't tell you what *kind* of device it is, so it doesn't help find a driver), but I don't think they're harmful.

* ACPI: fix synthetic HID for \_SB_Bjorn Helgaas2009-09-25
| | | | | | | | | | This makes \_SB_ show up as /sys/devices/LNXSYSTM:00/LNXSYBUS:00 rather than "device:00". This has been broken for a loooong time (at least since 2.6.13) because device->parent is an acpi_device pointer, not a handle.

* ACPI: handle re-enumeration, when acpi_devices might already existBjorn Helgaas2009-09-25
| | | | | | | | | | | | | | acpi_bus_scan() traverses the namespace to enumerate devices and uses acpi_add_single_object() to create acpi_devices. When the platform notifies us of a hot-plug event, we need to traverse part of the namespace again to figure out what appeared or disappeared. (We don't yet call acpi_bus_scan() during hot-plug, but I plan to do that in the future.) This patch makes acpi_add_single_object() notice when we already have an acpi_device, so we don't need to make a new one.

* ACPI: factor out device type and status checkingBjorn Helgaas2009-09-25
| | | | | | | | | | This patch adds acpi_bus_type_and_status(), which determines the type of the object and whether we want to build an acpi_device for it. If it is acpi_device-worthy, it returns the type and the device's current status. Signed-off-by: Bjorn Helgaas <bjorn.helgaas@hp.com> Signed-off-by: Len Brown <len.brown@intel.com>
* ACPI: add acpi_bus_get_status_handle()Bjorn Helgaas2009-09-25
| | | | | | | | | | | | Add acpi_bus_get_status_handle() so we can get the status of a namespace object before building a struct acpi_device. This removes a use of "device->flags.dynamic_status", a cached indicator of whether _STA exists. It seems simpler and more reliable to just evaluate _STA and catch AE_NOT_FOUND errors.

* ACPI: use acpi_walk_namespace() to enumerate devicesBjorn Helgaas2009-09-25
| | | | | | | | | | | | | | | | acpi_bus_scan() currently walks the namespace manually. This patch changes it to use acpi_walk_namespace() instead. Besides removing some complicated code, this means we take advantage of the namespace locking done by acpi_walk_namespace(). The locking isn't so important at boot-time, but I hope to eventually use this same path to handle hot-addition of devices, when it will be important. Note that acpi_walk_namespace() does not actually visit the starting node first, so we need to do that by hand first.

* ACPI: identify device tree root by null parent pointer, not ACPI_BUS_TYPEBjorn Helgaas2009-09-25
| | | | | | | | | | | | | We can identify the root of the ACPI device tree by the fact that it has no parent. This is simpler than passing around ACPI_BUS_TYPE_SYSTEM and will help remove special treatment of the device tree root. Currently, we add the root by hand with ACPI_BUS_TYPE_SYSTEM. If we traverse the tree treating the root as just another device and use acpi_get_type(), the root shows up as ACPI_TYPE_DEVICE.

* ACPI: enumerate namespace before adding functional fixed hardware devicesBjorn Helgaas2009-09-25
| | | | | | | | | | | This patch changes the order so we enumerate in the "root, namespace, functional fixed" order instead of the "root, functional fixed, namespace" order. When I change acpi_bus_scan() to use acpi_walk_namespace(), it will use the former order, so this patch isolates the order change for bisectability.

* ACPI: convert acpi_bus_scan() to operate on an acpi_handleBjorn Helgaas2009-09-25
| | | | | | | | | | | | | | | | | | This patch changes acpi_bus_scan() to take an acpi_handle rather than an acpi_device pointer. I plan to use acpi_bus_scan() in the hotplug path, and I'd rather not assume that notifications only go to nodes that already have acpi_devices. This will also help remove the special case for adding the root node. We currently add the root by hand before acpi_bus_scan(), but using a handle here means we can start the acpi_bus_scan() directly with the root even though it doesn't have an acpi_device yet. Note that acpi_bus_scan() currently adds and/or starts the *children* of its device argument. It doesn't do anything with the device itself.

* ACPI: add acpi_bus_get_parent() and remove "parent" argumentsBjorn Helgaas2009-09-25
| | | | | | | | | | | This patch adds acpi_bus_get_parent(), which ascends the namespace until it finds a parent with an acpi_device. Then we use acpi_bus_get_parent() in acpi_add_single_object(), so callers don't have to figure out or keep track of the parent acpi_device.

* ACPI: remove unnecessary argument checkingBjorn Helgaas2009-09-25
| | | | | | | | | acpi_add_single_object() is static, and all callers supply a valid "child" argument, so we don't need to check it. This patch also remove some unnecessary initializations. Signed-off-by: Bjorn Helgaas <bjorn.helgaas@hp.com> Signed-off-by: Len Brown <len.brown@intel.com>
* ACPI: remove redundant "type" argumentsBjorn Helgaas2009-09-25

* ACPI: remove acpi_device_set_context() "type" argumentBjorn Helgaas2009-09-25
| | | | | | | | | | We only pass the "type" to acpi_device_set_context() so we know whether the device has a handle to which we can attach the acpi_device pointer. But it's safer to just check for the handle directly, since it's in the acpi_device already. Signed-off-by: Bjorn Helgaas <bjorn.helgaas@hp.com> Signed-off-by: Len Brown <len.brown@intel.com>

* ACPI: save device_type in acpi_deviceBjorn Helgaas2009-09-25
| | | | | | | | | | | | | Most uses of the ACPI bus device_type (ACPI_BUS_TYPE_DEVICE, ACPI_BUS_TYPE_POWER, etc) are during device initialization, but we do need it later for notify handler installation, since that is different for fixed hardware devices vs. namespace devices. This patch saves the device_type in the acpi_device structure, so we can check that rather than comparing against the _HID string.

* ACPI: remove redundant "handle" and "parent" argumentsBjorn Helgaas2009-09-25
| | | | | | | | | | | In several cases, functions take handle and parent device pointers in addition to acpi_device pointers. But the acpi_device structure contains both the handle and the parent pointer, so it's pointless and error-prone to pass them all. This patch removes the unnecessary "handle" and "parent" arguments.

* ACPICA: fixup after acpi_get_object_info() changeBjorn Helgaas2009-09-25
| | | | | | | | | | | | | | | Commit 15b8dd53f5ffa changed info->hardware_id from a static array to a pointer. If hardware_id is non-NULL, it points to a NULL-terminated string, so we don't need to terminate it explicitly. However, it may be NULL; in that case, we *can't* add a NULL terminator. This causes a NULL pointer dereference oops for devices without _HID.

Though, there are few other issues with suspend/resume in this driver. The intention of calling free_irq() in suspend() was to avoid any possible spurious interrupts (see commit 5b039e681b8c5f30aac9cc04385 "3c59x PM fixes"). But, - On resume, the driver was requesting IRQ just after pci_set_master(), but before vortex_up() (which actually resets 3c59x chips). - Issuing free_irq() on a shared IRQ doesn't guarantee that a buggy HW won't trigger spurious interrupts in another driver that requested the same interrupt. So, if we want to protect from unexpected interrupts, then on suspend we should issue disable_irq(), not free_irq(). Signed-off-by: Anton Vorontsov <avorontsov@ru.mvista.com> Signed-off-by: David S.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Allocating a port number to a socket and hashing that socket shall be an atomic operation with regards to other port allocation. Otherwise, we could allocate a port that is already being allocated to another socket. Signed-off-by: Rémi Denis-Courmont <remi.denis-courmont@nokia.com> Signed-off-by: David S.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Previous update did not resched in inner loop causing watchdogs. Rewrite inner loop to: * account for delays better with less clock calls * more accurate timing of delay: - only delay if packet was successfully sent - if delay is 100ns and it takes 10ns to build packet then account for that * use wait_event_interruptible_timeout rather than open coding it.

| * | ipv4: check optlen for IP_MULTICAST_IF optionShan Wei2009-09-24
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Due to man page of setsockopt, if optlen is not valid, kernel should return -EINVAL. But a simple testcase as following, errno is 0, which means setsockopt is successful. addr.s_addr = inet_addr("192.1.2.3"); setsockopt(s, IPPROTO_IP, IP_MULTICAST_IF, &addr, 1); printf("errno is %d\n", errno); Xiaotian Feng(dfeng@redhat.com) caught the bug. We fix it firstly checking the availability of optlen and then dealing with the logic like other options.
