2020-11-23Bluetooth: revert: hci_h5: close serdev device and free hu in h5_closeHans de Goede
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 70f259a3f427 ("Bluetooth: hci_h5: close serdev device and free hu in h5_close"); v5 commit 855af2d74c87 ("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.

2020-11-11Bluetooth: hci_qca: Wait for timeout during suspendVenkata Lakshmi Narayana Gubba
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.

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.

When h5_close() gets called, the memory allocated for the hu gets freed only if hu->serdev doesn't exist. This leads to a memory leak. So when h5_close() is requested, close the serdev device instance and free the memory allocated to the hu entirely instead.

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().

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.

2020-11-07net: ipa: only enable GSI IEOB IRQs when neededAlex Elder
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().

2020-11-07net: ipa: only enable generic command completion IRQ when neededAlex Elder
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.

2020-11-07net: ipa: only enable GSI event control IRQs when neededAlex Elder
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().

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().

Introduce gsi_irq_init() and gsi_irq_exit(), to encapsulate looking up the GSI IRQ and registering its handler. Call gsi_irq_init() a little later in gsi_init(), and initialize the completion earlier. The IRQ handler accesses both the GSI virtual memory pointer and the completion, and this way these things will have been initialized before the gsi_irq() can ever be called.

2020-11-07net: ipa: refer to IPA versions, not GSIAlex Elder
The GSI code is now exposed to IPA version numbers, and we handle version-specific behavior based on the IPA version. Modify some comments that talk about GSI versions so they reference IPA versions instead. Correct version number errors in a couple of these comments. The (comment) mapping between IPA and GSI versions in the definition of the ipa_version enumerated type remains.

2020-11-07net: x25_asy: Delete the x25_asy driverXie He
This driver transports LAPB (X.25 link layer) frames over TTY links. I can safely say that this driver has no actual user because it was not working at all until: commit 8fdcabeac398 ("drivers/net/wan/x25_asy: Fix to make it work") The code in its current state still has problems: 1. The uses of "struct x25_asy" in x25_asy_unesc (when receiving) and in x25_asy_write_wakeup (when sending) are not protected by locks against x25_asy_change_mtu's changing of the transmitting/receiving buffers. Also, all "netif_running" checks in this driver are not protected by locks against the ndo_stop function. 2. The driver stops all TTY read/write when the netif is down. I think this is not right because this may cause the last outgoing frame before the netif goes down to be incompletely transmitted, and the first incoming frame after the netif goes up to be incompletely received. And there may also be other problems. I was planning to fix these problems but after recent discussions about deleting other old networking code, I think we may just delete this driver, too.

MDIO spec does not require an MDC at all times, only when MDIO transactions are occurring. This patch allows the xilinx_axienet driver to disable the MDC when not in use, and re-enable it when needed. It also simplifies the driver by removing MDC disable and enable in device reset sequence.
