When request_firmware() finds an already open firmware object it will wait for that object to become fully loaded and then check the status. As __fw_state_wait_common() succeeds the timeout value returned will be truncated in _request_firmware_prepare() and interpreted as -EPERM. Prior to "firmware: do not use fw_lock for fw_state protection" the code did test if we where in the "done" state before sleeping, causing this particular code path to succeed, in some cases. As the callers are interested in the result of the wait and not the remaining timeout the return value of __fw_state_wait_common() is changed to signal "done" or "error", which simplifies the logic in _request_firmware_load() as well.

fw_lock is to use to protect 'corner cases' inside firmware_class. It is not exactly clear what those corner cases are nor what it exactly protects. fw_state can be used without needing the fw_lock to protect its state transition and wake ups. fw_state is holds the state in status and the completion is used to wake up all waiters (in this case that is the user land helper so only one). This operation has to be 'atomic' to avoid races. We can do this by using swait which takes care we don't miss any wake up. We use also swait instead of wait because don't need all the additional features wait provides. Note there some more cleanups possible after with this change. For example for !CONFIG_FW_LOADER_USER_HELPER we don't check for the state anymore. Let's to this in the next patch instead mingling to many changes into this one. And yes you get a gcc warning "‘__fw_state_check’ defined but not used [-Wunused-function] code." for the time beeing. Cc: Ming Lei <ming.lei@canonical.com> Signed-off-by:

We track the state of the firmware loading with bit ops. Since the state machine has only a few states and they are all mutual exclusive there are only a few simple state transition we can model this simplify. UNKNOWN -> LOADING -> DONE | ABORTED Because we don't use any bit ops on fw_state::status anymore we are able to change the data type to enum fw_status and update the function arguments accordingly. READ_ONCE() and WRITE_ONCE() are propably not needed because there are a lot of load and stores around fw_st->status. But let's make it explicit and not be sorry later.

The firmware loader tracks the current state of the loading process via unsigned long status and a completion in struct firmware_buf. Instead of open code tracking the state, introduce data structure which encapsulate the state tracking and synchronization. While at it also separate UHM states from direct loading states, e.g. the loading_timeout is only defined when CONFIG_FW_LOADER_USER_HELPER. Cc: Ming Lei <ming.lei@canonical.com> Signed-off-by:

When you use the firmware usermode helper fallback with a timeout value set to a value greater than INT_MAX (2147483647) a cast overflow issue causes the timeout value to go negative and breaks all usermode helper loading. This regression was introduced through commit 68ff2a00 ("firmware_loader: handle timeout via wait_for_completion_interruptible_timeout()") on kernel v4.0. The firmware_class drivers relies on the firmware usermode helper fallback as a mechanism to look for firmware if the direct filesystem search failed only if: a) You've enabled CONFIG_FW_LOADER_USER_HELPER_FALLBACK (not many distros): Then all of these callers will rely on the fallback mechanism in case the firmware is not found through an initial direct filesystem lookup: o request_firmware() o request_firmware_into_buf() o request_firmware_nowait() b) If you've only enabled CONFIG_FW_LOADER_USER_HELPER (most distros): Then only callers using request_firmware_nowait() with the second argument set to false, this explicitly is requesting the UMH firmware fallback to be relied on in case the first filesystem lookup fails. Using Coccinelle SmPL grammar we have identified only two drivers explicitly requesting the UMH firmware fallback mechanism: - drivers/firmware/dell_rbu.c - drivers/leds/leds-lp55xx-common.c Since most distributions only enable CONFIG_FW_LOADER_USER_HELPER the biggest impact of this regression are users of the dell_rbu and leds-lp55xx-common device driver which required the UMH to find their respective needed firmwares. The default timeout for the UMH is set to 60 seconds always, as of commit 68ff2a00 ("firmware_loader: handle timeout via wait_for_completion_interruptible_timeout()") the timeout was bumped to MAX_JIFFY_OFFSET ((LONG_MAX >> 1)-1). Additionally the MAX_JIFFY_OFFSET value was also used if the timeout was configured by a user to 0. The following works: echo 2147483647 > /sys/class/firmware/timeout But both of the following set the timeout to MAX_JIFFY_OFFSET even if we display 0 back to userspace: echo 2147483648 > /sys/class/firmware/timeout cat /sys/class/firmware/timeout 0 echo 0> /sys/class/firmware/timeout cat /sys/class/firmware/timeout 0 A max value of INT_MAX (2147483647) seconds is therefore implicit due to the another cast with simple_strtol(). This fixes the secondary cast (the first one is simple_strtol() but its an issue only by forcing an implicit limit) by re-using the timeout variable and only setting retval in appropriate cases. Lastly worth noting systemd had ripped out the UMH firmware fallback mechanism from udev since udev 2014 via commit be2ea723b1d023b3d ("udev: remove userspace firmware loading support"), so as of systemd v217.

Few architectures like x86, ia64 and s390 derive the cache topology and all the properties using a specific architected mechanism while some other architectures like powerpc all those information id derived from the device tree. On ARM, both the mechanism is used. While all the cache properties can be derived in a architected way, it needs to rely on device tree to get the cache topology information. However there are few platforms where this architected mechanism is broken and the device tree properties can be used to override these incorrect values. This patch adds support for overriding the cache properties values to the values specified in the device tree.

ARM64 enables both CONFIG_OF and CONFIG_ACPI and the firmware can pass both ACPI tables and the device tree. Based on the kernel parameter, one of the two will be chosen. If acpi is enabled, then device tree is not unflattened. Currently ARM64 platforms report: " Failed to find cpu0 device node Unable to detect cache hierarchy from DT for CPU 0 " which is incorrect when booting with ACPI. Also latest ACPI v6.1 has no support for cache properties/hierarchy. This patch adds check for unflattened device tree and also returns as "not supported" if ACPI is runtime enabled. It also removes the reference to DT from the error message as the cache hierarchy can be detected from the firmware(OF/DT/ACPI) Cc: Greg Kroah-Hartman <gregkh@linuxfoundation.org> Signed-off-by:

With CONFIG_OF enabled on x86, we get the following error on boot: " Failed to find cpu0 device node Unable to detect cache hierarchy from DT for CPU 0 " and the cacheinfo fails to get populated in the corresponding sysfs entries. This is because cache_setup_of_node looks for of_node for setting up the shared cpu_map without checking that it's already populated in the architecture specific callback. In order to indicate that the shared cpu_map is already populated, this patch introduces a boolean `cpu_map_populated` in struct cpu_cacheinfo that can be used by the generic code to skip cache_shared_cpu_map_setup. This patch also sets that boolean for x86. Cc: Greg Kroah-Hartman <gregkh@linuxfoundation.org> Signed-off-by:

This test module tries to test asynchronous driver probing by having a driver that sleeps for an extended period of time (5 secs) in its probe() method. It measures the time needed to register this driver (with device already registered) and a new device (with driver already registered). The module will fail to load if the time spent in register call is more than half the probing sleep time. As a sanity check the driver will then try to synchronously register driver and device and fail if registration takes less than half of the probing sleep time. Signed-off-by:

Modify the runtime PM framework to use device links to ensure that supplier devices will not be suspended if any of their consumer devices are active. The idea is to reference count suppliers on the consumer's resume and drop references to them on its suspend. The information on whether or not the supplier has been reference counted by the consumer's (runtime) resume is stored in a new field (rpm_active) in the link object for each link. It may be necessary to clean up those references when the supplier is unbinding and that's why the links whose status is DEVICE_LINK_SUPPLIER_UNBIND are skipped by the runtime suspend and resume code. The above means that if the consumer device is probed in the runtime-active state, the supplier has to be resumed and reference counted by device_link_add() so the code works as expected on its (runtime) suspend. There is a new flag, DEVICE_LINK_RPM_ACTIVE, to tell device_link_add() about that (in which case the caller is responsible for making sure that the consumer really will be runtime-active when runtime PM is enabled for it). The other new link flag, DEVICE_LINK_PM_RUNTIME, tells the core whether or not the link should be used for runtime PM at all. Signed-off-by:

Currently, there is a problem with taking functional dependencies between devices into account. What I mean by a "functional dependency" is when the driver of device B needs device A to be functional and (generally) its driver to be present in order to work properly. This has certain consequences for power management (suspend/resume and runtime PM ordering) and shutdown ordering of these devices. In general, it also implies that the driver of A needs to be working for B to be probed successfully and it cannot be unbound from the device before the B's driver. Support for representing those functional dependencies between devices is added here to allow the driver core to track them and act on them in certain cases where applicable. The argument for doing that in the driver core is that there are quite a few distinct use cases involving device dependencies, they are relatively hard to get right in a driver (if one wants to address all of them properly) and it only gets worse if multiplied by the number of drivers potentially needing to do it. Morever, at least one case (asynchronous system suspend/resume) cannot be handled in a single driver at all, because it requires the driver of A to wait for B to suspend (during system suspend) and the driver of B to wait for A to resume (during system resume). For this reason, represent dependencies between devices as "links", with the help of struct device_link objects each containing pointers to the "linked" devices, a list node for each of them, status information, flags, and an RCU head for synchronization. Also add two new list heads, representing the lists of links to the devices that depend on the given one (consumers) and to the devices depended on by it (suppliers), and a "driver presence status" field (needed for figuring out initial states of device links) to struct device. The entire data structure consisting of all of the lists of link objects for all devices is protected by a mutex (for link object addition/removal and for list walks during device driver probing and removal) and by SRCU (for list walking in other case that will be introduced by subsequent change sets). If CONFIG_SRCU is not selected, however, an rwsem is used for protecting the entire data structure. In addition, each link object has an internal status field whose value reflects whether or not drivers are bound to the devices pointed to by the link or probing/removal of their drivers is in progress etc. That field is only modified under the device links mutex, but it may be read outside of it in some cases (introduced by subsequent change sets), so modifications of it are annotated with WRITE_ONCE(). New links are added by calling device_link_add() which takes three arguments: pointers to the devices in question and flags. In particular, if DL_FLAG_STATELESS is set in the flags, the link status is not to be taken into account for this link and the driver core will not manage it. In turn, if DL_FLAG_AUTOREMOVE is set in the flags, the driver core will remove the link automatically when the consumer device driver unbinds from it. One of the actions carried out by device_link_add() is to reorder the lists used for device shutdown and system suspend/resume to put the consumer device along with all of its children and all of its consumers (and so on, recursively) to the ends of those lists in order to ensure the right ordering between all of the supplier and consumer devices. For this reason, it is not possible to create a link between two devices if the would-be supplier device already depends on the would-be consumer device as either a direct descendant of it or a consumer of one of its direct descendants or one of its consumers and so on. There are two types of link objects, persistent and non-persistent. The persistent ones stay around until one of the target devices is deleted, while the non-persistent ones are removed automatically when the consumer driver unbinds from its device (ie. they are assumed to be valid only as long as the consumer device has a driver bound to it). Persistent links are created by default and non-persistent links are created when the DL_FLAG_AUTOREMOVE flag is passed to device_link_add(). Both persistent and non-persistent device links can be deleted with an explicit call to device_link_del(). Links created without the DL_FLAG_STATELESS flag set are managed by the driver core using a simple state machine. There are 5 states each link can be in: DORMANT (unused), AVAILABLE (the supplier driver is present and functional), CONSUMER_PROBE (the consumer driver is probing), ACTIVE (both supplier and consumer drivers are present and functional), and SUPPLIER_UNBIND (the supplier driver is unbinding). The driver core updates the link state automatically depending on what happens to the linked devices and for each link state specific actions are taken in addition to that. For example, if the supplier driver unbinds from its device, the driver core will also unbind the drivers of all of its consumers automatically under the assumption that they cannot function properly without the supplier. Analogously, the driver core will only allow the consumer driver to bind to its device if the supplier driver is present and functional (ie. the link is in the AVAILABLE state). If that's not the case, it will rely on the existing deferred probing mechanism to wait for the supplier driver to become available. Signed-off-by:

Pull driver core fixes from Greg KH: "Here are two small driver core / kernfs fixes for 4.9-rc3. One makes the Kconfig entry for DEBUG_TEST_DRIVER_REMOVE a bit more explicit that this is a crazy thing to enable for a distro kernel (thanks for trying Fedora!), the other resolves an issue with vim opening kernfs files (sysfs, configfs, etc.) Both have been in linux-next with no reported issues" * tag 'driver-core-4.9-rc3' of git://git.kernel.org/pub/scm/linux/kernel/git/gregkh/driver-core: driver core: Make Kconfig text for DEBUG_TEST_DRIVER_REMOVE stronger kernfs: Add noop_fsync to supported kernfs_file_fops

Pull staging and IIO driver fixes from Greg KH: "Here are some small staging and iio driver fixes for reported issues for 4.9-rc3. Nothing major, the "largest" being a lustre fix for a sysfs file that was obviously wrong, and had never been tested, so it was moved to debugfs as that is where it belongs.
