From 3e58044b61a92ad63e52b347782248659b6b6f12 Mon Sep 17 00:00:00 2001 From: Kalle Valo Date: Wed, 25 Nov 2015 15:38:34 +0200 Subject: [PATCH] ath10k: print crc32 checksums for firmware and board files To detect cases if the firmare or board file is corrupted or otherwise modified print crc32 value of both. Now the output looks like: ath10k_pci 0000:02:00.0: pci irq msi interrupts 1 irq_mode 0 reset_mode 0 ath10k_pci 0000:02:00.0: qca99x0 hw2.0 target 0x01000000 chip_id 0x003801ff sub 168c:0002 ath10k_pci 0000:02:00.0: kconfig debug 1 debugfs 1 tracing 1 dfs 1 testmode 1 ath10k_pci 0000:02:00.0: firmware ver 10.4.1.00030-1 api 5 features no-p2p crc32 d2901e01 ath10k_pci 0000:02:00.0: board_file api 1 bmi_id 1:1 crc32 7e56fd07 ath10k_pci 0000:02:00.0: htt-ver 2.2 wmi-op 6 htt-op 4 cal otp max-sta 512 raw 0 hwcrypto 1 Signed-off-by: Kalle Valo --- drivers/net/wireless/ath/ath10k/Kconfig | 1 + drivers/net/wireless/ath/ath10k/debug.c | 12 ++++++++---- 2 files changed, 9 insertions(+), 4 deletions(-) diff --git a/drivers/net/wireless/ath/ath10k/Kconfig b/drivers/net/wireless/ath/ath10k/Kconfig index 72acb82..03aa35f 100644 --- a/drivers/net/wireless/ath/ath10k/Kconfig +++ b/drivers/net/wireless/ath/ath10k/Kconfig @@ -2,6 +2,7 @@ config ATH10K tristate "Atheros 802.11ac wireless cards support" depends on MAC80211 && HAS_DMA select ATH_COMMON + select CRC32 ---help--- This module adds support for wireless adapters based on Atheros IEEE 802.11ac family of chipsets. diff --git a/drivers/net/wireless/ath/ath10k/debug.c b/drivers/net/wireless/ath/ath10k/debug.c index ea8b562..4fc3d4f 100644 --- a/drivers/net/wireless/ath/ath10k/debug.c +++ b/drivers/net/wireless/ath/ath10k/debug.c @@ -19,6 +19,8 @@ #include #include #include +#include +#include #include "core.h" #include "debug.h" @@ -141,10 +143,11 @@ void ath10k_debug_print_hwfw_info(struct ath10k *ar) config_enabled(CONFIG_ATH10K_DFS_CERTIFIED), config_enabled(CONFIG_NL80211_TESTMODE)); - ath10k_info(ar, "firmware ver %s api %d features %s\n", + ath10k_info(ar, "firmware ver %s api %d features %s crc32 %08x\n", ar->hw->wiphy->fw_version, ar->fw_api, - fw_features); + fw_features, + crc32_le(0, ar->firmware->data, ar->firmware->size)); } void ath10k_debug_print_board_info(struct ath10k *ar) @@ -157,9 +160,10 @@ void ath10k_debug_print_board_info(struct ath10k *ar) else scnprintf(boardinfo, sizeof(boardinfo), "N/A"); - ath10k_info(ar, "board_file api %d bmi_id %s", + ath10k_info(ar, "board_file api %d bmi_id %s crc32 %08x", ar->bd_api, - boardinfo); + boardinfo, + crc32_le(0, ar->board->data, ar->board->size)); } void ath10k_debug_print_boot_info(struct ath10k *ar) -- 2.7.4
