Add a pointer to the iwl_trans structure and point it to the trans
part of the cfg. This is the first step in disassociating the trans
configuration from the rest of the configuration.
Signed-off-by: Luca Coelho <luciano.coelho@intel.com>
|
|
In order to be able to select the cfg depending on the HW revision or
on the RF ID, we need to set up the trans before selecting the cfg.
To do so, move the elements from cfg that are needed by
iwl_trans_alloc() to a separate struct at the top of the cfg, so it
can be used by other cfg types as well, before selecting the rest of
the configuration.

Reimplement debug TLV allocation flow. The driver will check the
validity of the debug TLVs prior allocating space for them.
Any malformed or unsupported TLV will be skipped.
The TLV specific checks will be added in later patches.

Use a linked list to maintain the debug TLVs instead of a single buffer.
This way, the driver does not need to iterate over the binary file twice
and allocates smaller chunks of memory. Also, in case one allocation
fails the driver will work with the partial configuration instead of
aborting the entire debug configuration.

In the error handling code of iwl_req_fw_callback(), iwl_dealloc_ucode()
is called to free data. In iwl_drv_stop(), iwl_dealloc_ucode() is called
again, which can cause double-free problems.
To fix this bug, the call to iwl_dealloc_ucode() in
iwl_req_fw_callback() is deleted.
This bug is found by a runtime fuzzing tool named FIZZER written by us.

Add new API and TLV for the ability to send commands in the beginning
and end of reset flow.
The full flow of recovery is:
1. While loading FW, get address (from the TLV) of target buffer
to read in case of reset
2. If an error/assert happens read the address data from step 1.
3. Reset the HW and load the FW.
4. Send the data read in step 2.
5. Add station keys
6. Send notification to FW that reset flow is done.
The main use of the recovery flow is for support in PN/SN recovery
when offloaded

received from alive notification.

If we fail to to grab NIC access because the device is not responding
(i.e. CSR_GP_CNTRL returns 0xFFFFFFFF), remove the device from the PCI
bus, to avoid any further damage, and to let the user space rescan.
In order to inform the userspace that a rescan is needed, we send a
kobject uevent with "INACCESSIBLE".
This functionality is disabled by default, but can be enabled via a
new module parameter called "remove_when_gone". In the future we may
change this module parameter to include 3 modes instead: do nothing;
auto-rescan or; send uevent.
