The string memory needs to be null-terminated to avoid the undefined garbage appended by the subsequent board file name creation. ath10k_pci 0000:04:00.0: failed to fetch board data for "bus=pci,vendor=168c,device=003e,subsystem-vendor=168c,subsystem-device=3363��P�����" from ath10k/QCA6174/hw3.0/board-2.bin Fixes: f2593cb1b291 ("ath10k: Search SMBIOS for OEM board file extension") Reported-by: Kalle Valo Signed-off-by: Ryan Hsu Signed-off-by: Kalle Valo --- diff --git a/drivers/net/wireless/ath/ath10k/core.c b/drivers/net/wireless/ath/ath10k/core.c index 499ee7b41771..59729aa8cd82 100644 --- a/drivers/net/wireless/ath/ath10k/core.c +++ b/drivers/net/wireless/ath/ath10k/core.c @@ -1126,7 +1126,7 @@ static int ath10k_core_create_board_name(struct ath10k *ar, char *name, size_t name_len) { /* strlen(',variant=') + strlen(ar->id.bdf_ext) */ - char variant[9 + ATH10K_SMBIOS_BDF_EXT_STR_LENGTH]; + char variant[9 + ATH10K_SMBIOS_BDF_EXT_STR_LENGTH] = { 0 }; if (ar->id.bmi_ids_valid) { scnprintf(name, name_len,
