New subject: [PATCH AUTOSEL 5.10 02/93] ASoC: Intel: sof_sdw: add mutual exclusion between PCH DMIC and RT715

From: Pierre-Louis Bossart pierre-louis.bossart@linux.intel.com

[ Upstream commit 35564e2bf94611c3eb51d35362addb3cb394ad54 ]

When external RT714/715 devices are used for capture, we don't want the PCH DMICs to be used.

Any information provided by the SOF platform driver or DMI quirks will be overridden.

New subject: [PATCH AUTOSEL 5.10 06/93] srcu: Fix broken node geometry after early ssp init

From: Frederic Weisbecker frederic@kernel.org

[ Upstream commit b5befe842e6612cf894cf4a199924ee872d8b7d8 ]

An srcu_struct structure that is initialized before rcu_init_geometry() will have its srcu_node hierarchy based on CONFIG_NR_CPUS. Once rcu_init_geometry() is called, this hierarchy is compressed as needed for the actual maximum number of CPUs for this system.

Later on, that srcu_struct structure is confused, sometimes referring to its initial CONFIG_NR_CPUS-based hierarchy, and sometimes instead to the new num_possible_cpus() hierarchy. For example, each of its ->mynode fields continues to reference the original leaf rcu_node structures, some of which might no longer exist. On the other hand, srcu_for_each_node_breadth_first() traverses to the new node hierarchy.

There are at least two bad possible outcomes to this:

1) a) A callback enqueued early on an srcu_data structure (call it *sdp) is recorded pending on sdp->mynode->srcu_data_have_cbs in srcu_funnel_gp_start() with sdp->mynode pointing to a deep leaf (say 3 levels).

b) The grace period ends after rcu_init_geometry() shrinks the nodes level to a single one. srcu_gp_end() walks through the new srcu_node hierarchy without ever reaching the old leaves so the callback is never executed.

This is easily reproduced on an 8 CPUs machine with CONFIG_NR_CPUS >= 32 and "rcupdate.rcu_self_test=1". The srcu_barrier() after early tests verification never completes and the boot hangs:

2) An srcu_struct structure that is initialized before rcu_init_geometry() and used afterward will always have stale rdp->mynode references, resulting in callbacks to be missed in srcu_gp_end(), just like in the previous scenario.

This commit therefore causes init_srcu_struct_nodes to initialize the geometry, if needed. This ensures that the srcu_node hierarchy is properly built and distributed from the get-go.

New subject: [PATCH AUTOSEL 5.10 07/93] rcu: Reject RCU_LOCKDEP_WARN() false positives

From: "Paul E. McKenney" paulmck@kernel.org

[ 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.

[ Upstream commit 8cac2f6eb8548245e6f8fb893fc7f2a714952654 ]

SYSRQ doesn't work with DMA. This is because there is no error indication whether a symbol had a framing error or not. Actually, this is not completely correct, there is a bit in the data register which is set in this case, but we'd have to read change the DMA access to 16 bit and we'd need to post process the data, thus make the DMA pointless in the first place.

New subject: [PATCH AUTOSEL 5.10 10/93] serial: 8250: of: Check for CONFIG_SERIAL_8250_BCM7271

From: Jim Quinlan jim2101024@gmail.com

[ 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.

New subject: [PATCH AUTOSEL 5.10 11/93] misc/libmasm/module: Fix two use after free in ibmasm_init_one

From: Lv Yunlong lyl2019@mail.ustc.edu.cn

[ Upstream commit 7272b591c4cb9327c43443f67b8fbae7657dd9ae ]

In ibmasm_init_one, it calls ibmasm_init_remote_input_dev(). Inside ibmasm_init_remote_input_dev, mouse_dev and keybd_dev are allocated by input_allocate_device(), and assigned to sp->remote.mouse_dev and sp->remote.keybd_dev respectively.

In the err_free_devices error branch of ibmasm_init_one, mouse_dev and keybd_dev are freed by input_free_device(), and return error. Then the execution runs into error_send_message error branch of ibmasm_init_one, where ibmasm_free_remote_input_dev(sp) is called to unregister the freed sp->remote.mouse_dev and sp->remote.keybd_dev.

My patch add a "error_init_remote" label to handle the error of ibmasm_init_remote_input_dev(), to avoid the uaf bugs.

New subject: [PATCH AUTOSEL 5.10 12/93] misc: alcor_pci: fix null-ptr-deref when there is no PCI bridge

From: Tong Zhang ztong0001@gmail.com

[ Upstream commit 3ce3e45cc333da707d4d6eb433574b990bcc26f5 ]

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.

[ Upstream commit 41120ebbb1eb5e9dec93320e259d5b2c93226073 ]

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.

New subject: [PATCH AUTOSEL 5.10 18/93] ALSA: usx2y: Don't call free_pages_exact() with NULL address

From: Takashi Iwai tiwai@suse.de

[ Upstream commit cae0cf651adccee2c3f376e78f30fbd788d0829f ]

New subject: [PATCH AUTOSEL 5.10 19/93] Revert "ALSA: bebob/oxfw: fix Kconfig entry for Mackie d.2 Pro"

From: Takashi Sakamoto o-takashi@sakamocchi.jp

[ Upstream commit 5d6fb80a142b5994355ce675c517baba6089d199 ]

This reverts commit 0edabdfe89581669609eaac5f6a8d0ae6fe95e7f.

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.

New subject: [PATCH AUTOSEL 5.10 25/93] scsi: lpfc: Fix "Unexpected timeout" error in direct attach topology

From: James Smart jsmart2021@gmail.com

[ 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).

New subject: [PATCH AUTOSEL 5.10 27/93] scsi: core: Cap scsi_host cmd_per_lun at can_queue

From: John Garry john.garry@huawei.com

[ 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.

pm_runtime_get_sync will increment pm usage counter even it failed. Forgetting to putting operation will result in reference leak here. Fix it by replacing it with pm_runtime_resume_and_get to keep usage counter balanced.

From: Christophe JAILLET christophe.jaillet@wanadoo.fr

[ Upstream commit fad92b11047a748c996ebd6cfb164a63814eeb2e ]

In the probe function, if the final 'serial_config()' fails, 'info' is leaking.

Add a resource handling path to free this memory.

New subject: [PATCH AUTOSEL 5.10 31/93] scsi: core: Fixup calling convention for scsi_mode_sense()

From: Hannes Reinecke hare@suse.de

[ 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.

New subject: [PATCH AUTOSEL 5.10 35/93] scsi: megaraid_sas: Early detection of VD deletion through RaidMap update

From: Kashyap Desai kashyap.desai@broadcom.com

[ 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.

New subject: [PATCH AUTOSEL 5.10 36/93] scsi: megaraid_sas: Handle missing interrupts while re-enabling IRQs

From: Chandrakanth Patil chandrakanth.patil@broadcom.com

[ Upstream commit 9bedd36e9146b34dda4d6994e3aa1d72bc6442c1 ]

While reenabling the IRQ after IRQ poll there may be a small window for the firmware to post the replies with interrupts raised. In that case the driver will not see the interrupts which leads to I/O timeout.

This issue only happens when there are many I/O completions on a single reply queue. This forces the driver to switch between the interrupt and IRQ context.

Make the driver process the reply queue one more time after enabling the IRQ.

From: Mike Christie michael.christie@oracle.com

[ Upstream commit b1d19e8c92cfb0ded180ef3376c20e130414e067 ]

There are a couple places where we could free the iscsi_cls_conn while it's still in use. This adds some helpers to get/put a refcount on the struct and converts an exiting user. Subsequent commits will then use the helpers to fix 2 bugs in the eh code.

New subject: [PATCH AUTOSEL 5.10 38/93] scsi: iscsi: Fix conn use after free during resets

From: Mike Christie michael.christie@oracle.com

[ 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.

New subject: [PATCH AUTOSEL 5.10 39/93] scsi: iscsi: Fix shost->max_id use

From: Mike Christie michael.christie@oracle.com

[ Upstream commit bdd4aad7ff92ae39c2e93c415bb6761cb8b584da ]

The iscsi offload drivers are setting the shost->max_id to the max number of sessions they support. The problem is that max_id is not the max number of targets but the highest identifier the targets can have. To use it to limit the number of targets we need to set it to max sessions - 1, or we can end up with a session we might not have preallocated resources for.

New subject: [PATCH AUTOSEL 5.10 41/93] scsi: qedi: Fix race during abort timeouts

From: Mike Christie michael.christie@oracle.com

[ Upstream commit 2ce002366a3fcc3f9616d4583194f65dde0ad253 ]

If the SCSI cmd completes after qedi_tmf_work calls iscsi_itt_to_task then the qedi qedi_cmd->task_id could be freed and used for another cmd. If we then call qedi_iscsi_cleanup_task with that task_id we will be cleaning up the wrong cmd.

Wait to release the task_id until the last put has been done on the iscsi_task. Because libiscsi grabs a ref to the task when sending the abort, we know that for the non-abort timeout case that the task_id we are referencing is for the cmd that was supposed to be aborted.

A latter commit will fix the case where the abort times out while we are running qedi_tmf_work.

From: Mike Christie michael.christie@oracle.com

[ Upstream commit 2819b4ae2873d50fd55292877b0231ec936c3b2e ]

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.

We have started to get a bunch of pointless dmamask not set warnings that makes the output of dmesg -l err,warn hard to read with many extra warnings:

cpcap-regulator cpcap-regulator.0: DMA mask not set cpcap_adc cpcap_adc.0: DMA mask not set cpcap_battery cpcap_battery.0: DMA mask not set cpcap-charger cpcap-charger.0: DMA mask not set cpcap-pwrbutton cpcap-pwrbutton.0: DMA mask not set cpcap-led cpcap-led.0: DMA mask not set cpcap-led cpcap-led.1: DMA mask not set cpcap-led cpcap-led.2: DMA mask not set cpcap-led cpcap-led.3: DMA mask not set cpcap-led cpcap-led.4: DMA mask not set cpcap-rtc cpcap-rtc.0: DMA mask not set cpcap-usb-phy cpcap-usb-phy.0: DMA mask not set

This seems to have started with commit 4d8bde883bfb ("OF: Don't set default coherent DMA mask"). We have the parent SPI controller use DMA, while CPCAP driver and it's children do not. For audio, the DMA is handled over I2S bus with the McBSP driver.

From: Eli Billauer eli.billauer@gmail.com

[ Upstream commit 1b1ee3a91d21fdf7d415c1060db1a7a07ae296b6 ]

As Xillybus' configuration symbol hierarchy has been reorganized recently, the correct condition for compiling the xillybus/ subdirectory is now CONFIG_XILLYBUS_CLASS, and not CONFIG_XILLYBUS.

CONFIG_XILLYBUS_CLASS will be introduced in v5.14, so backporting this commit will break the kernel's build.

Since this patch was created for three kernel versions, I'm repeating this response on all three, just be sure. Hope I'm not being annoying.

New subject: [PATCH AUTOSEL 5.10 49/93] serial: tty: uartlite: fix console setup

From: Daniel Mack daniel@zonque.org

[ Upstream commit d157fca711ad42e75efef3444c83d2e1a17be27a ]

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.

New subject: [PATCH AUTOSEL 5.10 56/93] iommu/arm-smmu: Fix arm_smmu_device refcount leak when arm_smmu_rpm_get fails

From: Xiyu Yang xiyuyang19@fudan.edu.cn

[ 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.

From: Michael Kelley mikelley@microsoft.com

[ Upstream commit 52e1b3b3daa9d53f0204bf474ee1d4b1beb38234 ]

Hyper-V is observed to sometimes set multiple flags in the srb_status, such as ABORTED and ERROR. Current code in storvsc_handle_error() handles only a single flag being set, and does nothing when multiple flags are set. Fix this by changing the case statement into a series of "if" statements testing individual flags. The functionality for handling each flag is unchanged.

From: Athira Rajeev atrajeev@linux.vnet.ibm.com

[ Upstream commit 45677c9aebe926192e59475b35a1ff35ff2d4217 ]

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.

From: Heiko Carstens hca@linux.ibm.com

[ Upstream commit 9c9a915afd90f7534c16a71d1cd44b58596fddf3 ]

s390 is the only architecture which makes use of the __no_kasan_or_inline attribute for two functions. Given that both stap() and __load_psw_mask() are very small functions they can and should be always inlined anyway.

Therefore get rid of __no_kasan_or_inline and always inline these functions.

New subject: [PATCH AUTOSEL 5.10 70/93] s390/ipl_parm: fix program check new psw handling

From: Heiko Carstens hca@linux.ibm.com

[ Upstream commit 88c2510cecb7e2b518e3c4fdf3cf0e13ebe9377c ]

The __diag308() 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.

A user of FFADO project reported the issue of ToneWeal FW66. As a result, the device is identified as one of applications of BeBoB solution.

I note that in the report the device returns contradictory result in plug discovery process for audio subunit. Fortunately ALSA BeBoB driver doesn't perform it thus it's likely to handle the device without issues.

I receive no reaction to test request for this patch yet, however it would be worth to add support for it.

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.

From: Jiajun Cao jjcao20@fudan.edu.cn

[ Upstream commit 8c13212443230d03ff25014514ec0d53498c0912 ]

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.

New subject: [PATCH AUTOSEL 5.10 90/93] i2c: core: Disable client irq on reboot/shutdown

From: Dmitry Torokhov dmitry.torokhov@gmail.com

[ Upstream commit b64210f2f7c11c757432ba3701d88241b2b98fb1 ]

If an i2c client receives an interrupt during reboot or shutdown it may be too late to service it by making an i2c transaction on the bus because the i2c controller has already been shutdown. This can lead to system hangs if the i2c controller tries to make a transfer that is doomed to fail because the access to the i2c pins is already shut down, or an iommu translation has been torn down so i2c controller register access doesn't work.

Let's simply disable the irq if there isn't a shutdown callback for an i2c client when there is an irq associated with the device. This will make sure that irqs don't come in later than the time that we can handle it. We don't do this if the i2c client device already has a shutdown callback because presumably they're doing the right thing and quieting the device so irqs don't come in after the shutdown callback returns.

New subject: [PATCH AUTOSEL 5.10 92/93] lib/decompress_unlz4.c: correctly handle zero-padding around initrds.

From: Dimitri John Ledkov dimitri.ledkov@canonical.com

[ Upstream commit 2c484419efc09e7234c667aa72698cb79ba8d8ed ]

lz4 compatible decompressor is simple. The format is underspecified and relies on EOF notification to determine when to stop. Initramfs buffer format[1] explicitly states that it can have arbitrary number of zero padding. Thus when operating without a fill function, be extra careful to ensure that sizes less than 4, or apperantly empty chunksizes are treated as EOF.

To test this I have created two cpio initrds, first a normal one, main.cpio. And second one with just a single /test-file with content "second" second.cpio. Then i compressed both of them with gzip, and with lz4 -l. Then I created a padding of 4 bytes (dd if=/dev/zero of=pad4 bs=1 count=4). To create four testcase initrds:

1) main.cpio.gzip + extra.cpio.gzip = pad0.gzip 2) main.cpio.lz4 + extra.cpio.lz4 = pad0.lz4 3) main.cpio.gzip + pad4 + extra.cpio.gzip = pad4.gzip 4) main.cpio.lz4 + pad4 + extra.cpio.lz4 = pad4.lz4

The pad4 test-cases replicate the initrd load by grub, as it pads and aligns every initrd it loads.

All of the above boot, however /test-file was not accessible in the initrd for the testcase #4, as decoding in lz4 decompressor failed. Also an error message printed which usually is harmless.

Whith a patched kernel, all of the above testcases now pass, and /test-file is accessible.

This fixes lz4 initrd decompress warning on every boot with grub. And more importantly this fixes inability to load multiple lz4 compressed initrds with grub. This patch has been shipping in Ubuntu kernels since January 2021.

New subject: [PATCH AUTOSEL 5.10 93/93] kcov: add __no_sanitize_coverage to fix noinstr for all architectures

From: Marco Elver elver@google.com

[ 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.
