There have been multiple revisions of the patch fix the h5->rx_skb leak. Accidentally the first revision (which is buggy) and v5 have both been merged: v1 commit 70f259a3 ("Bluetooth: hci_h5: close serdev device and free hu in h5_close"); v5 commit 855af2d7 ("Bluetooth: hci_h5: fix memory leak in h5_close") The correct v5 makes changes slightly higher up in the h5_close() function, which allowed both versions to get merged without conflict. The changes from v1 unconditionally frees the h5 data struct, this is wrong because in the serdev enumeration case the memory is allocated in h5_serdev_probe() like this: h5 = devm_kzalloc(dev, sizeof(*h5), GFP_KERNEL); So its lifetime is tied to the lifetime of the driver being bound to the serdev and it is automatically freed when the driver gets unbound. In the serdev case the same h5 struct is re-used over h5_close() and h5_open() calls and thus MUST not be free-ed in h5_close(). The serdev_device_close() added to h5_close() is incorrect in the same way, serdev_device_close() is called on driver unbound too and also MUST no be called from h5_close(). This reverts the changes made by merging v1 of the patch, so that just the changes of the correct v5 remain. Cc: Anant Thazhemadam <anant.thazhemadam@gmail.com> Signed-off-by:

Currently qca_suspend() is relied on IBS mechanism. During FW download and memory dump collections, IBS will be disabled. In those cases, driver will allow suspend and still uses the serdev port, which results to errors. Now added a wait timeout if suspend is triggered during FW download and memory collections.

When h5_close() is called, h5 is directly freed when !hu->serdev. However, h5->rx_skb is not freed, which causes a memory leak. Freeing h5->rx_skb and setting it to NULL, fixes this memory leak.

Some platforms keep USB power even when they are powered off and in S5, this makes Realtek 8821C keep its firmware even after a cold boot, and make 8821C never load new firmware. So use vendor specific HCI command to ask 8821C drop its firmware after system shutdown. Newer firmware doesn't have this issue so we only use this trick for old 8821C firmware version. Suggested-by:

When an LE connection request is made, advertising is disabled and never resumed. When a client has an active advertisement, this is disruptive. This change adds resume logic for client-configured (non-directed) advertisements after the connection attempt. The patch was tested by registering an advertisement, initiating an LE connection from a remote peer, and verifying that the advertisement is re-activated after the connection is established. This is performed on Hatch and Kukui Chromebooks. Signed-off-by:

Alex Elder says: ==================== net: ipa: constrain GSI interrupts The goal of this series is to more tightly control when GSI interrupts are enabled. This is a long-ish series, so I'll describe it in parts. The first patch is actually unrelated... I forgot to include it in my previous series (which exposed the GSI layer to the IPA version). It is a trivial comments-only update patch. The second patch defers registering the GSI interrupt handler until *after* all of the resources that handler touches have been initialized. In practice, we don't see this interrupt that early, but this precludes an obvious problem. The next two patches are simple changes. The first just trivially renames a field. The second switches from using constant mask values to using an enumerated type of bit positions to represent each GSI interrupt type. The rest implement the "real work." First, all interrupts are disabled at initialization time. Next, we keep track of a bitmask of enabled GSI interrupt types, updating it each time we enable or disable one of them. From there we have a set of patches that one-by-one enable each interrupt type only during the period it is required. This includes allowing a channel to generate IEOB interrupts only when it has been enabled. And finally, the last patch simplifies some code now that all GSI interrupt types are handled uniformly. ==================== Link: https://lore.kernel.org/r/20201105181407.8006-1-elder@linaro.orgSigned-off-by:

Now that all of the GSI interrupts are handled uniformly, change gsi_irq_type_update() so it takes a value. Have the function assign that value to the cached mask of enabled GSI IRQ types before writing it to hardware. Note that gsi_irq_teardown() will only be called after gsi_irq_disable(), so it's not necessary for the former to disable all IRQ types. Get rid of that. Signed-off-by:

Most GSI general errors are unrecoverable without a full reset. Despite that, we want to receive these errors so we can at least report what happened before whatever undefined behavior ensues. Explicitly disable all such interrupts in gsi_irq_setup(), then enable those we want in gsi_irq_enable(). List the interrupt types we are interested in (everything but breakpoint) explicitly rather than using GSI_CNTXT_GSI_IRQ_ALL, and remove that symbol's definition. Signed-off-by:

It is possible for other execution environments (EEs, like the modem) to request changes to local (AP) channel or event ring state. We do not support this feature. In gsi_irq_setup(), explicitly zero the mask that defines which channels are permitted to generate inter-EE channel state change interrupts. Do the same for the event ring mask. Signed-off-by:

A GSI channel must be started in order to use it to perform a transfer data (or command) transaction. And the only time we'll see an IEOB interrupt is if we send a transaction to a started channel. Therefore we do not need to have the IEOB interrupt type enabled until at least one channel has been started. And once the last started channel has been stopped, we can disable the IEOB interrupt type again. We already enable the IEOB interrupt for a particular channel only when it is started. Extend that by having the IEOB interrupt *type* be enabled only when at least one channel is in STARTED state. Disallow all channels from triggering the IEOB interrupt in gsi_irq_setup(). We only enable an channel's interrupt when needed, so there is no longer any need to zero the channel mask in gsi_irq_disable(). Signed-off-by:

The completion of a generic EE GSI command is signaled by a global interrupt of type GP_INT1. The only other used type for a global interrupt is a hardware error report. First, disallow all global interrupt types in gsi_irq_setup(). We want to know about hardware errors, so re-enable the interrupt type in gsi_irq_enable(), to allow hardware errors to be reported. Disable that interrupt type again in gsi_irq_disable(). We only issue generic EE commands one at a time, and there's no reason to keep the completion interrupt enabled when no generic EE command is pending. We furthermore have no need to enable the GP_INT2 or GP_INT3 interrupt types (which aren't used). The change in gsi_irq_enable() makes GSI_CNTXT_GLOB_IRQ_ALL unused, so get rid of it. Have gsi_generic_command() enable the GP_INT1 interrupt type (in addition to the ERROR_INT type) only while a generic command is pending. Signed-off-by:

A GSI event ring causes an event control interrupt to fire whenever its state changes (between NOT_ALLOCATED and ALLOCATED). No event ring should ever change state except when we request it to. Currently, we permit *all* events rings to generate event control interrupts--even those that are never used. And we enable event control interrupts essentially at all times, from setup to teardown. Instead, only enable the event control interrupt type for the duration of an event ring command, and when doing so, only allow the event ring being operated upon to cause the interrupt to fire. Disallow all event rings from issuing the event control interrupt in gsi_irq_setup(). Because an event ring's interrupt is only enabled when needed, there is no longer any need to zero the event channel mask in gsi_irq_disable(). Signed-off-by:

A GSI channel causes a channel control interrupt to fire whenever its state changes (between NOT_ALLOCATED, ALLOCATED, STARTED, etc.).

Currently, we permit *all* channels to generate channel control interrupts--even those that are never used. And we enable channel control interrupts essentially at all times, from setup to teardown. Instead, disable all channel control interrupts initially in gsi_irq_setup(), and only enable the channel control interrupt type for the duration of a channel command. When doing so, only allow the channel being operated upon to cause the interrupt to fire. Because a channel's interrupt is now enabled only when needed (one channel at a time), there is no longer any need to zero the channel mask in gsi_irq_disable(). Add new gsi_irq_type_enable() and gsi_irq_type_disable() as helper functions to control whether a given GSI interrupt type is enabled. Signed-off-by:

Introduce gsi_irq_setup() and gsi_irq_teardown() to disable all GSI interrupts when first setting up GSI hardware, and to clean things up when we're done. Re-enable all GSI interrupt types in gsi_irq_enable(), but do so only after each of the type-specific interrupt masks has been configured. Similarly, disable all interrupt types in gsi_irq_disable()--first--before zeroing out the type-specific masks. Signed-off-by:
