[PATCH AUTOSEL 4.19 01/39] tty: serial: fsl_lpuart: fix the potential risk of division or modulo by zero
From: Sherry Sun sherry.sun@nxp.com
[ Upstream commit fcb10ee27fb91b25b68d7745db9817ecea9f1038 ]
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.

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.

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.

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.

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.

scsi_execute() will now return a negative error if there was an error prior to command submission; evaluate that instead if checking for DRIVER_ERROR.

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.

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.

[ 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.

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.

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.

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 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 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.

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.
