__driver_attach()

driver_probe_device()
pci_enable_sriov()
pci_iov_add_virtfn()
pci_device_add()
aer_isr() <--- pci aer error

pci_walk_bus()
down_read(&pci_bus_sem) <--- rd sem
down_write(&pci_bus_sem) <-- stuck on wr sem
report_error_detected()
device_lock(&dev->mutex)<--- DEAD LOCK
This can also happen when aer error occurs while pci_dev->sriov_config() is
called.
This patch does a pci_bus_walk and adds all the devices to a list. After
unlocking (up_read) &pci_bus_sem, we go through the list and call
err_handler of the devices with devic_lock() held. This way, we dont try
to hold both locks at same time.
v2:
* Drop patch 1, 2 & 4.
* Instead of locking 50+ devices, do get_device() and add them to a list.
After unlocking &pci_bus_sem, go through the list call err_handler.
v1:
* Previous discussion here: https://lkml.org/lkml/2017/9/27/720

__driver_attach()
device_lock(&dev->mutex) <--- device mutex lock here
driver_probe_device()
pci_enable_sriov()
pci_iov_add_virtfn()
pci_device_add()
aer_isr() <--- pci aer error
do_recovery()
broadcast_error_message()
pci_walk_bus()
down_read(&pci_bus_sem) <--- rd sem
down_write(&pci_bus_sem) <-- stuck on wr sem
report_error_detected()
device_lock(&dev->mutex)<--- DEAD LOCK
This can also happen when aer error occurs while pci_dev->sriov_config() is
called.
This patch does a pci_bus_walk and adds all the devices to a list. After
unlocking (up_read) &pci_bus_sem, we go through the list and call
err_handler of the devices with devic_lock() held. This way, we dont try
to hold both locks at same time.
v2:
* Drop patch 1, 2 & 4.
* Instead of locking 50+ devices, do get_device() and add them to a list.
After unlocking &pci_bus_sem, go through the list call err_handler.
v1:
* Previous discussion here: https://lkml.org/lkml/2017/9/27/720

commit 301c26a018acb94dd537a4418cefa0f654500c6f
category: bugfix
bugzilla: https://gitee.com/src-openeuler/kernel/issues/IBRED3
CVE: CVE-2024-58077
Reference: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?…
--------------------------------
commit 1f5664351410 ("ASoC: lower "no backend DAIs enabled for ... Port"
log severity") ignores -EINVAL error message on common soc_pcm_ret().
It is used from many functions, ignoring -EINVAL is over-kill.
The reason why -EINVAL was ignored was it really should only be used
upon invalid parameters coming from userspace and in that case we don't
want to log an error since we do not want to give userspace a way to do
a denial-of-service attack on the syslog / diskspace.
So don't use soc_pcm_ret() on .prepare callback is better idea.

device_lock(&dev->mutex)<--- DEAD LOCK
This can also happen when aer error occurs while pci_dev->sriov_config() is
called.
This patch does a pci_bus_walk and adds all the devices to a list. After
unlocking (up_read) &pci_bus_sem, we go through the list and call
err_handler of the devices with devic_lock() held. This way, we dont try
to hold both locks at same time.
v2:
* Drop patch 1, 2 & 4.
* Instead of locking 50+ devices, do get_device() and add them to a list.
After unlocking &pci_bus_sem, go through the list call err_handler.
v1:
* Previous discussion here: https://lkml.org/lkml/2017/9/27/720
