R. Silva <gustavoars@kernel.org> # Date: Wed Mar 10 19:40:43 2021 -0600 # # media: siano: Fix out-of-bounds warnings in smscore_load_firmware_family2() # # Rename struct sms_msg_data4 to sms_msg_data5 and increase the size of # its msg_data array from 4 to 5 elements. Notice that at some point # the 5th element of msg_data is being accessed in function # smscore_load_firmware_family2(): # # 1006 trigger_msg->msg_data[4] = 4; /* Task ID / # # Also, there is no need for the object _trigger_msg_ of type struct # sms_msg_data , when _msg_ can be used, directly. Notice that msg_data # in struct sms_msg_data is a one-element array, which causes multiple # out-of-bounds warnings when accessing beyond its first element # in function smscore_load_firmware_family2(): # # 992 struct sms_msg_data trigger_msg = # 993 (struct sms_msg_data ) msg; # 994 # 995 pr_debug("sending MSG_SMS_SWDOWNLOAD_TRIGGER_REQ\n"); # 996 SMS_INIT_MSG(&msg->x_msg_header, # 997 MSG_SMS_SWDOWNLOAD_TRIGGER_REQ, # 998 sizeof(struct sms_msg_hdr) + # 999 sizeof(u32) * 5); # 1000 # 1001 trigger_msg->msg_data[0] = firmware->start_address; # 1002 /* Entry point / # 1003 trigger_msg->msg_data[1] = 6; / Priority / # 1004 trigger_msg->msg_data[2] = 0x200; / Stack size / # 1005 trigger_msg->msg_data[3] = 0; / Parameter / # 1006 trigger_msg->msg_data[4] = 4; / Task ID / # # even when enough dynamic memory is allocated for _msg_: # # 929 / PAGE_SIZE buffer shall be enough and dma aligned / # 930 msg = kmalloc(PAGE_SIZE, GFP_KERNEL \| coredev->gfp_buf_flags); # # but as _msg_ is casted to (struct sms_msg_data ): # # 992 struct sms_msg_data trigger_msg = # 993 (struct sms_msg_data ) msg; # # the out-of-bounds warnings are actually valid and should be addressed. # # Fix this by declaring object _msg_ of type struct sms_msg_data5 , # which contains a 5-elements array, instead of just 4.
