2018-11-26sandbox: Use malloc() and free() from os layerSimon Glass
At present sandbox calls malloc() from various places in the OS layer and this results in calls to U-Boot's malloc() implementation. It is better to use the on in the OS layer, since it does not mix allocations with the main U-Boot code. Fix this by replacing calls with malloc() to os_malloc(), etc. Signed-off-by: Simon Glass <sjg@chromium.org> Reviewed-by: Joe Hershberger <joe.hershberger@ni.com>
2018-07-26sandbox: eth-raw: Add a SIMPLE_BUS to enumerate host interfacesJoe Hershberger
Ask the OS for each of its interfaces and for each one, bind a U-Boot device and then probe it. This will allocate the priv data structure that is then populated. Signed-off-by: Joe Hershberger <joe.hershberger@ni.com> Reviewed-by: Simon Glass <sjg@chromium.org>
2018-07-26sandbox: eth-raw: Allow interface to be specified by indexJoe Hershberger
With systemd stable interface names, eth0 will almost never exist. Instead of using that name in the sandbox.dts, use an index. Signed-off-by: Joe Hershberger <joe.hershberger@ni.com> Reviewed-by: Simon Glass <sjg@chromium.org>

Instead of doing a simple string compare against "lo", look for the flag that indicates a localhost interface. Signed-off-by: Joe Hershberger <joe.hershberger@ni.com> Reviewed-by: Simon Glass <sjg@chromium.org>

2018-07-26sandbox: eth-raw: Make sure descriptors are always initializedJoe Hershberger
If we let descriptors equal 0, we can end up closing STDIN. Make sure they start out as -1. Signed-off-by: Joe Hershberger <joe.hershberger@ni.com> Reviewed-by: Simon Glass <sjg@chromium.org>
2018-07-26sandbox: eth-raw: Correct valid socket test in send/recvJoe Hershberger
In open, the socket is correctly checked to be -1 in the error case. In send and recv, we checked for 0, but that is a valid socket number. Correct this by checking for -1 as a bad socket everywhere. Signed-off-by: Joe Hershberger <joe.hershberger@ni.com> Reviewed-by: Simon Glass <sjg@chromium.org>
2018-05-07SPDX: Convert all of our single license tags to Linux Kernel styleTom Rini
When U-Boot started using SPDX tags we were among the early adopters and there weren't a lot of other examples to borrow from. So we picked the area of the file that usually had a full license text and replaced it with an appropriate SPDX-License-Identifier: entry. Since then, the Linux Kernel has adopted SPDX tags and they place it as the very first line in a file (except where shebangs are used, then it's second line) and with slightly different comment styles than us. In part due to community overlap, in part due to better tag visibility and in part for other minor reasons, switch over to that style. This commit changes all instances where we have a single declared license in the tag as both the before and after are identical in tag contents. There's also a few places where I found we did not have a tag and have introduced one. Signed-off-by: Tom Rini <trini@konsulko.com>
2016-01-15eth-raw-os.c: Add cast to bind(2) callTom Rini
With more recent gcc versions we otherwise get an error like: note: expected 'const struct sockaddr *' but argument is of type 'struct sockaddr_in *' and the common solution here is to cast, rather than re-work the code.

Coverity notes that we do not ensure when we copy ifname we still have space left to ensure NULL termination. As cannot control the size of ifr_name we must make sure that our argument will not overflow the buffer.

2015-04-18sandbox: eth: Add support for using the 'lo' interfaceJoe Hershberger
The 'lo' interface on Linux doesn't support thinks like ARP or link-layer access like we use to talk to a normal network interface. A higher-level network API must be used to access localhost. As written, this interface is limited to not supporting ICMP since the API doesn't allow the socket to be opened for all IP traffic and be able to receive at the same time. UDP is far more useful to test with, so it was selected over ICMP. Ping won't work, but things like TFTP should work.

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 <joe.hershberger@ni.com> Reviewed-by: Simon Glass <sjg@chromium.org>
