+ [ 4.157072] iwlwifi 0000:00:14.3: maximum version supported: (efault)128
+ [ 4.157073] iwlwifi 0000:00:14.3: check
git://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git
+
+ This is a design flaw in iwlwifi driver source.
+
+ In drivers/net/wireless/intel/iwlwifi/pcie/drv.c
+
+ static const struct pci_device_id iwl_hw_card_ids[] = {
+ {IWL_PCI_DEVICE(0x4232, 0x1201, iwl5100_agn_cfg)},
+ ...
+ {IWL_PCI_DEVICE(0x43F0, PCI_ANY_ID, iwl_qu_long_latency_trans_cfg)},
+ ...
+ };
+
+ The third argument to IWL_PCI_DEVICE macro will be assigned to driver_data
field
+ of struct pci_device_id. However, iwl5100_agn_cfg has type struct iwl_cfg, and
+ yet iwl_qu_long_latency_trans_cfg has type struct iwl_cfg_trans_params.
+
+ struct iwl_cfg_trans_params {
+ ...
+ };
+
+ struct iwl_cfg {
+ struct iwl_cfg_trans_params trans;
+ const char *name;
+ const char *fw_name_pre;
+ ...
+ };
+
+ It's fine to cast a pointer to struct iwl_cfg, but it's not always valid to
cast
+ a struct iwl_cfg_trans_params to struct iwl_cfg.
+
+ In function iwl_pci_probe, it tries to find an alternative cfg by iterating
+ throughout iwl_dev_info_table, but in our case, [8086:43f0] subsystem
+ [1a56:1652], all of the candidates will be skipped, and
+ iwl_qu_long_latency_trans_cfg will be assigned as the ultimate struct iwl_cfg,
+ which will be certainly wrong when you're trying to refer to anything beyond
+ sizeof(struct iwl_cfg_trans_params), e.g. cfg->fw_name_pre. In this case,
+ ((struct iwl_cfg_trans_params*)&iwl_qu_long_latency_trans_cfg)->name will be
+ "'", and ((struct
iwl_cfg_trans_params*)&iwl_qu_long_latency_trans_cfg)->fw_name_pre
+ gives "(efault)", pure garbage data.
+
+ [Fix]
+
+ Commit 410f758529bc ("iwlwifi: add new cards for So and Qu family") in
v5.12-rc1
+ add a few additional entries to correctly catch this card.
+
+ [Test Case]
+
+ Booting from kernel built with aforementioned commit cherry-picked, WiFi
+ interface should be now up and working. Also tested this kernel against
several
+ iwlwifi supported models on the target and a previous generation platform.
+
+ [Where problems could occur]
+
+ This card failed initialization previously. With it being up and running, it
may
+ affect system stability if there are some undiscovered bugs related to this
new
+ model.
+
+ [Other Info]
+
+ This change has been backported to stable kernel v5.11.4, so skipped
nomination
+ for Hirsute/Unstable.

Intel AX210 Wi-Fi [8086:43f0] subsystem [1a56:1652] requests invalid

git://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git
This is a design flaw in iwlwifi driver source.
In drivers/net/wireless/intel/iwlwifi/pcie/drv.c
static const struct pci_device_id iwl_hw_card_ids[] = {
{IWL_PCI_DEVICE(0x4232, 0x1201, iwl5100_agn_cfg)},
...
{IWL_PCI_DEVICE(0x43F0, PCI_ANY_ID, iwl_qu_long_latency_trans_cfg)},
...
};
The third argument to IWL_PCI_DEVICE macro will be assigned to driver_data
field
of struct pci_device_id. However, iwl5100_agn_cfg has type struct iwl_cfg, and
yet iwl_qu_long_latency_trans_cfg has type struct iwl_cfg_trans_params.
struct iwl_cfg_trans_params {
...
};
struct iwl_cfg {
struct iwl_cfg_trans_params trans;
const char *name;
const char *fw_name_pre;
...
};
It's fine to cast a pointer to struct iwl_cfg, but it's not always valid to
cast
a struct iwl_cfg_trans_params to struct iwl_cfg.
In function iwl_pci_probe, it tries to find an alternative cfg by iterating
throughout iwl_dev_info_table, but in our case, [8086:43f0] subsystem
[1a56:1652], all of the candidates will be skipped, and
iwl_qu_long_latency_trans_cfg will be assigned as the ultimate struct iwl_cfg,
which will be certainly wrong when you're trying to refer to anything beyond
sizeof(struct iwl_cfg_trans_params), e.g. cfg->fw_name_pre. In this case,
((struct iwl_cfg_trans_params*)&iwl_qu_long_latency_trans_cfg)->name will be
"'", and ((struct
iwl_cfg_trans_params*)&iwl_qu_long_latency_trans_cfg)->fw_name_pre
gives "(efault)", pure garbage data.
[Fix]
Commit 410f758529bc ("iwlwifi: add new cards for So and Qu family") in
v5.12-rc1
add a few additional entries to correctly catch this card.
[Test Case]
Booting from kernel built with aforementioned commit cherry-picked, WiFi
interface should be now up and working. Also tested this kernel against
several
iwlwifi supported models on the target and a previous generation platform.
[Where problems could occur]
This card failed initialization previously. With it being up and running, it
may
affect system stability if there are some undiscovered bugs related to this
new
model.
[Other Info]
This change has been backported to stable kernel v5.11.4, so skipped
nomination
for Hirsute/Unstable.
