From a346ca7902a185a1974d50d60790d34715be886e Mon Sep 17 00:00:00 2001 From: Joe Hershberger Date: Sun, 22 Mar 2015 17:09:21 -0500 Subject: sandbox: eth: Add a bridge to a real network for sandbox Implement a bridge between U-Boot's network stack and Linux's raw packet API allowing the sandbox to send and receive packets using the host machine's network interface. This raw Ethernet API requires elevated privileges. You can either run as root, or you can add the capability needed like so: sudo /sbin/setcap "CAP_NET_RAW+ep" /path/to/u-boot Signed-off-by: Joe Hershberger Reviewed-by: Simon Glass --- arch/sandbox/include/asm/eth-raw-os.h | 32 ++++++++++++++++++++++++++++++++ 1 file changed, 32 insertions(+) create mode 100644 arch/sandbox/include/asm/eth-raw-os.h (limited to 'arch/sandbox/include/asm/eth-raw-os.h') diff --git a/arch/sandbox/include/asm/eth-raw-os.h b/arch/sandbox/include/asm/eth-raw-os.h new file mode 100644 index 0000000..df60c4f --- /dev/null +++ b/arch/sandbox/include/asm/eth-raw-os.h @@ -0,0 +1,32 @@ +/* + * Copyright (c) 2015 National Instruments + * + * (C) Copyright 2015 + * Joe Hershberger + * + * SPDX-License-Identifier: GPL-2.0 + */ + +#ifndef __ETH_RAW_OS_H +#define __ETH_RAW_OS_H + +/** + * struct eth_sandbox_raw_priv - raw socket session + * + * sd: socket descriptor - the open socket during a session + * device: struct sockaddr_ll - the host interface packets move to/from + */ +struct eth_sandbox_raw_priv { + int sd; + void *device; +}; + +int sandbox_eth_raw_os_start(const char *ifname, unsigned char *ethmac, + struct eth_sandbox_raw_priv *priv); +int sandbox_eth_raw_os_send(void *packet, int length, + const struct eth_sandbox_raw_priv *priv); +int sandbox_eth_raw_os_recv(void *packet, int *length, + const struct eth_sandbox_raw_priv *priv); +void sandbox_eth_raw_os_stop(struct eth_sandbox_raw_priv *priv); + +#endif /* __ETH_RAW_OS_H */ -- cgit v1.1
