[ Upstream commit 3066820034b5dd4e89bd74a7739c51c2d6f5e554 ]

If another lockdep report runs concurrently with an RCU lockdep report from RCU_LOCKDEP_WARN(), the following sequence of events can occur:

1. debug_lockdep_rcu_enabled() sees that lockdep is enabled when called from (say) synchronize_rcu().

2. Lockdep is disabled by a concurrent lockdep report.

3. debug_lockdep_rcu_enabled() evaluates its lockdep-expression argument, for example, lock_is_held(&rcu_bh_lock_map).

4. Because lockdep is now disabled, lock_is_held() plays it safe and returns the constant 1.

5. But in this case, the constant 1 is not safe, because invoking synchronize_rcu() under rcu_read_lock_bh() is disallowed.

6. debug_lockdep_rcu_enabled() wrongly invokes lockdep_rcu_suspicious(), resulting in a false-positive splat.

This commit therefore changes RCU_LOCKDEP_WARN() to check debug_lockdep_rcu_enabled() after checking the lockdep expression, so that any "safe" returns from lock_is_held() are rejected by debug_lockdep_rcu_enabled(). This requires memory ordering, which is supplied by READ_ONCE(debug_locks). The resulting volatile accesses prevent the compiler from reordering and the fact that only one variable is being accessed prevents the underlying hardware from reordering. The combination works for IA64, which can reorder reads to the same location, but this is defeated by the volatile accesses, which compile to load instructions that provide ordering.

We should be very careful about the register values that will be used for division or modulo operations, althrough the possibility that the UARTBAUD register value is zero is very low, but we had better to deal with the "bad data" of hardware in advance to avoid division or modulo by zero leading to undefined kernel behavior.

[ Upstream commit f5b08386dee439c7a9e60ce0a4a4a705f3a60dff ]

Our SoC's have always had a NS16650A UART core and older SoC's would have a compatible string of: 'compatible = ""ns16550a"' and use the 8250_of driver. Our newer SoC's have added enhancements to the base core to add support for DMA and accurate high speed baud rates and use this newer 8250_bcm7271 driver. The Device Tree node for our enhanced UARTs has a compatible string of: 'compatible = "brcm,bcm7271-uart", "ns16550a"''. With both drivers running and the link order setup so that the 8250_bcm7217 driver is initialized before the 8250_of driver, we should bind the 8250_bcm7271 driver to the enhanced UART, or for upstream kernels that don't have the 8250_bcm7271 driver, we bind to the 8250_of driver.

The problem is that when both the 8250_of and 8250_bcm7271 drivers were running, occasionally the 8250_of driver would be bound to the enhanced UART instead of the 8250_bcm7271 driver. This was happening because we use SCMI based clocks which come up late in initialization and cause probe DEFER's when the two drivers get their clocks.

Occasionally the SCMI clock would become ready between the 8250_bcm7271 probe and the 8250_of probe and the 8250_of driver would be bound. To fix this we decided to config only our 8250_bcm7271 driver and added "ns16665a0" to the compatible string so the driver would work on our older system.

This commit has of_platform_serial_probe() check specifically for the "brcm,bcm7271-uart" and whether its companion driver is enabled. If it is the case, and the clock provider is not ready, we want to make sure that when the 8250_bcm7271.c driver returns EPROBE_DEFER, we are not getting the UART registered via 8250_of.c.

There is an issue with the ASPM(optional) capability checking function. A device might be attached to root complex directly, in this case, bus->self(bridge) will be NULL, thus priv->parent_pdev is NULL. Since alcor_pci_init_check_aspm(priv->parent_pdev) checks the PCI link's ASPM capability and populate parent_cap_off, which will be used later by alcor_pci_aspm_ctrl() to dynamically turn on/off device, what we can do here is to avoid checking the capability if we are on the root complex. This will make pdev_cap_off 0 and alcor_pci_aspm_ctrl() will simply return when bring called, effectively disable ASPM for the device.

In both the probe() error path and remove() pm_runtime_put_noidle() is called which will decrement the runtime pm reference count. However, there is no matching function to have raised the reference count. Not this isn't a fix as the runtime pm core will stop the reference count going negative anyway.

An alternative would have been to raise the count in these paths, but it is not clear why that would be necessary.

I've explained that optional FireWire card for d.2 is also built-in to d.2 Pro, however it's wrong. The optional card uses DM1000 ASIC and has 'Mackie DJ Mixer' in its model name of configuration ROM. On the other hand, built-in FireWire card for d.2 Pro and d.4 Pro uses OXFW971 ASIC and has 'd.Pro' in its model name according to manuals and user experiences. The former card is not the card for d.2 Pro. They are similar in appearance but different internally.

The purpose of the w1_ds2438_get_page function is to get the register values at the page passed as the pageno parameter. However, the page0 was hardcoded, such that the function always returned the page0 contents. Fixed so that the function can retrieve any page.

[ Upstream commit e30d55137edef47434c40d7570276a0846fe922c ]

An 'unexpected timeout' message may be seen in a point-2-point topology. The message occurs when a PLOGI is received before the driver is notified of FLOGI completion. The FLOGI completion failure causes discovery to be triggered for a second time. The discovery timer is restarted but no new discovery activity is initiated, thus the timeout message eventually appears.

In point-2-point, when discovery has progressed before the FLOGI completion is processed, it is not a failure. Add code to FLOGI completion to detect that discovery has progressed and exit the FLOGI handling (noop'ing it).

[ Upstream commit ea2f0f77538c50739b9fb4de4700cee5535e1f77 ]

The sysfs handling function sdev_store_queue_depth() enforces that the sdev queue depth cannot exceed shost can_queue. The initial sdev queue depth comes from shost cmd_per_lun. However, the LLDD may manually set cmd_per_lun to be larger than can_queue, which leads to an initial sdev queue depth greater than can_queue.

Such an issue was reported in [0], which caused a hang. That has since been fixed in commit fc09acb7de31 ("scsi: scsi_debug: Fix cmd_per_lun, set to max_queue").

Stop this possibly happening for other drivers by capping shost cmd_per_lun at shost can_queue.

[ Upstream commit 8793613de913e03e7c884f4cc56e350bc716431e ]

The description for scsi_mode_sense() claims to return the number of valid bytes on success, which is not what the code does. Additionally there is no gain in returning the SCSI status, as everything the callers do is to check against scsi_result_is_good(), which is what scsi_mode_sense() does already. So change the calling convention to return a standard error code on failure, and 0 on success, and adapt the description and all callers.

[ Upstream commit ae6874ba4b43c5a00065f48599811a09d33b873d ]

Consider the case where a VD is deleted and the targetID of that VD is assigned to a newly created VD. If the sequence of deletion/addition of VD happens very quickly there is a possibility that second event (VD add) occurs even before the driver processes the first event (VD delete). As event processing is done in deferred context the device list remains the same (but targetID is re-used) so driver will not learn the VD deletion/additon. I/Os meant for the older VD will be directed to new VD which may lead to data corruption.

Make driver detect the deleted VD as soon as possible based on the RaidMap update and block further I/O to that device.

[ Upstream commit 891e2639deae721dc43764a44fa255890dc34313 ]

During ep_disconnect we have been doing iscsi_suspend_tx/queue to block new I/O but every driver except cxgbi and iscsi_tcp can still get I/O from __iscsi_conn_send_pdu() if we haven't called iscsi_conn_failure() before ep_disconnect. This could happen if we were terminating the session, and the logout timed out before it was even sent to libiscsi.

Fix the issue by adding a helper which reverses the bind_conn call that allows new I/O to be queued. Drivers implementing ep_disconnect can use this to make sure new I/O is not queued to them when handling the disconnect.

[ Upstream commit ec29d0ac29be366450a7faffbcf8cba3a6a3b506 ]

If we haven't done a unbind target call we can race where iscsi_conn_teardown wakes up the EH thread and then frees the conn while those threads are still accessing the conn ehwait.

We can only do one TMF per session so this just moves the TMF fields from the conn to the session. We can then rely on the iscsi_session_teardown->iscsi_remove_session->__iscsi_unbind_session call to remove the target and it's devices, and know after that point there is no device or scsi-ml callout trying to access the session.

Drivers shouldn't be calling block/unblock session for tmf handling because the functions can change the session state from under libiscsi. iscsi_queuecommand's call to iscsi_prep_scsi_cmd_pdu-> iscsi_check_tmf_restrictions will prevent new cmds from being sent to qedi after we've started handling a TMF. So we don't need to try and block it in the driver, and we can remove these block calls.

Remove the hack to assign the global console_port variable at probe time. This assumption that cons->index is -1 is wrong for systems that specify 'console=' in the cmdline (or 'stdout-path' in dts). Hence, on such system the actual console assignment is ignored, and the first UART that happens to be probed is used as console instead.

Move the logic to console_setup() and map the console to the correct port through the array of available ports instead.

snd_sb_qsound_destroy() contains the calls of removing the previously created mixer controls, but it doesn't clear the pointers. As snd_sb_qsound_destroy() itself may be repeatedly called via ioctl, this could lead to double-free potentially.

Fix it by clearing the struct fields properly afterwards.

[ Upstream commit 1adf30f198c26539a62d761e45af72cde570413d ]

arm_smmu_rpm_get() invokes pm_runtime_get_sync(), which increases the refcount of the "smmu" even though the return value is less than 0.

The reference counting issue happens in some error handling paths of arm_smmu_rpm_get() in its caller functions. When arm_smmu_rpm_get() fails, the caller functions forget to decrease the refcount of "smmu" increased by arm_smmu_rpm_get(), causing a refcount leak.

Fix this issue by calling pm_runtime_resume_and_get() instead of pm_runtime_get_sync() in arm_smmu_rpm_get(), which can keep the refcount balanced in case of failure.

Current code in storvsc_handle_error() handles only a single flag being set, and does nothing when multiple flags are set.

The "no_handler_test" in ebb selftests attempts to read the PMU registers twice via helper function "dump_ebb_state". First dump is just before closing of event and the second invocation is done after closing of the event. The original intention of second dump_ebb_state was to dump the state of registers at the end of the test when the counters are frozen. But this will be achieved with the first call itself since sample period is set to low value and PMU will be frozen by then. Hence patch removes the dump which was done before closing of the event.

The __diag260() inline asm temporarily changes the program check new psw to redirect a potential program check on the diag instruction. Restoring of the program check new psw is done in C code behind the inline asm.

This can be problematic, especially if the function is inlined, since the compiler can reorder instructions in such a way that a different instruction, which may result in a program check, might be executed before the program check new psw has been restored.

To avoid such a scenario move restoring into the inline asm. For consistency reasons move also saving of the original program check new psw into the inline asm.

Inside function hideep_nvm_unlock(), variable "unmask_code" could be uninitialized if hideep_pgm_r_reg() returns error, however, it is used in the later if statement after an "and" operation, which is potentially unsafe.

[ Upstream commit 3f605ee17f8e785ba6ff69bee8e584e377a3cf28 ]

The kernel test robot reports that the "screen_bits" splash screen data is missing for the dragen platform:

arch/m68k/68000/dragen2.c:73:16: error: 'screen_bits' undeclared (first use in this function) 73 | LSSA = (long) screen_bits; | ^~~~~~~~~~~ arch/m68k/68000/dragen2.c:73:16: note: each undeclared identifier is reported only once for each function it appears in

Digging around a bit I found the screen_bits data structure was originally in a screen.h file that was generated from a screen.xbm file. That was removed in commit 0c0e6db80683 ("m68k: drop unused parts of 68VZ328 Makefile").

Other splash screen initializers for 68000 targets are kept here as the C data structures so lets do the same for this one. Add the missing screen.h file and include it in the dragen specific startup code.

[ Upstream commit 9b5ddea9ce5a68d7d2bedcb69901ac2a86c96c7b ]

The private->vol_updated flag was being checked outside of the mutex_lock/unlock() of private->data_mutex leading to the volume data being fetched twice from the device unnecessarily or old volume data being returned.

Update scarlett2_*_ctl_get() and include the private->vol_updated flag check inside the critical region.

Running sparse checker it shows warning message about incorrect endianness used for descriptor initialization:

| f_hid.c:91:43: warning: incorrect type in initializer (different base types) | f_hid.c:91:43: expected restricted __le16 [usertype] bcdHID | f_hid.c:91:43: got int

Fixing issue with cpu_to_le16() macro, however this is not a real issue as the value is the same both endians.

The function hda_tegra_first_init() neglects to check the return value after executing platform_get_irq().

hda_tegra_first_init() should check the return value (if negative error number) for errors so as to not pass a negative value to the devm_request_irq().

Fix it by adding a check for the return value irq_id.

Some devices don't drain their pipelines if we don't make sure that the corresponding output port is in reset before programming it for a new trace capture, resulting in bits of old trace appearing in the new trace capture. Fix that by explicitly making sure the reset is asserted before programming new trace capture.

[ Upstream commit 540540d06e9d9b3769b46d88def90f7e7c002322 ]

Until now no compiler supported an attribute to disable coverage instrumentation as used by KCOV.

To work around this limitation on x86, noinstr functions have their coverage instrumentation turned into nops by objtool. However, this solution doesn't scale automatically to other architectures, such as arm64, which are migrating to use the generic entry code.

Clang [1] and GCC [2] have added support for the attribute recently. [1] https://github.com/llvm/llvm-project/commit/280333021e9550d80f5c1152a34e33e8... [2] https://gcc.gnu.org/git/?p=gcc.git%3Ba=commit%3Bh=cec4d4a6782c9bd8d071839c50... The changes will appear in Clang 13 and GCC 12.

Add __no_sanitize_coverage for both compilers, and add it to noinstr.

Note: In the Clang case, __has_feature(coverage_sanitizer) is only true if the feature is enabled, and therefore we do not require an additional defined(CONFIG_KCOV) (like in the GCC case where __has_attribute(..) is always true) to avoid adding redundant attributes to functions if KCOV is off. That being said, compilers that support the attribute will not generate errors/warnings if the attribute is redundantly used; however, where possible let's avoid it as it reduces preprocessed code size and associated compile-time overheads.
