2019-11-20net/mlxfw: Verify FSM error code translation doesn't exceed array sizeEran Ben Elisha1-0/+2
Array mlxfw_fsm_state_err_str contains value to string translation, when values are provided by mlxfw_dev. If value is larger than MLXFW_FSM_STATE_ERR_MAX, return "unknown error" as expected instead of reading an address than exceed array size.

2017-07-03net/mlxfw: Properly handle dependancy with non-loadable mlx5Or Gerlitz1-1/+1
If mlx5 is set to be built-in and mlxfw as a module, we get a link error: drivers/built-in.o: In function `mlx5_firmware_flash': (.text+0x5aed72): undefined reference to `mlxfw_firmware_flash' Since we don't want to mandate selecting mlxfw for mlx5 users, we use the IS_REACHABLE macro to make sure that a stub is exposed to the caller.

2017-06-22mlxfw: Make the module selectableOr Gerlitz2-1/+16
There are upcoming NIC (mlx5) use-cases where people want to avoid building the mlxfw module, allow for that. The mlxsw module is untouched and keeps selecting mlxfw.

2017-06-14net/mlxfw: fix a NULL dereferenceDan Carpenter1-0/+1
If we hit this error path we end up returning ERR_PTR(0) which is NULL. The caller is not expecting that so it results in a NULL dereference.

2017-05-25Add the mlxfw module for Mellanox firmware flash processYotam Gigi11-0/+1527
The mlxfw module is in charge of common logic needed to flash Mellanox devices firmware, which consists of: - Parse the Mellanox Firmware Archive version 2 (MFA2) format, which is the format used to store the Mellanox firmware. The MFA2 format file can hold firmware for many different silicon variants, differentiated by a unique ID called PSID. In addition, the MFA2 file data section is compressed using xz compression to save both file-system space and memory at extraction time. - Implement the firmware flash state machine logic, which is a common logic for Mellanox products needed to flash the firmware to the device. As the module is shared between different Mellanox products, it defines a set of callbacks to be implemented by the specific driver for hardware interaction.
