net: Always build the string_to_enetaddr() helper

2019-12-09T15:47:41+00:00

Part of the env cleanup moved this out of the environment code and into
the net code. However, this helper is sometimes needed even when the net
stack isn't included.

Move the helper to lib/net_utils.c like it's similarly-purposed
string_to_ip(). Also rename the moved function to similar naming.

common: Move env_get_ip() to net.h

2019-12-02T23:23:09+00:00

This function relates to networking, so move it out of the common.h
header file.

net: make net_random_ethaddr() more random

2019-09-04T16:37:19+00:00

The net_random_ethaddr() tries to get some entropy from different
startup times of a board. The seed is initialized with get_timer() which
has only a granularity of milliseconds. We can do better if we use
get_ticks() which returns the raw timer ticks. Using this we have a
higher chance of getting different values at startup.

net: unaligned copying of unsigned long

2019-07-18T21:37:13+00:00

The inline functions net_read_u32() and net_copy_u32() have been created to
copy unaligned u32. But this is not obvious to the compiler. GCC 9.1
introduces a check -Werror=address-of-packed-member which leads to a build
error on Travis CI:

net/bootp.c: In function ‘dhcp_send_request_packet’:
net/bootp.c:1011:27: error: taking address of packed member of
‘struct bootp_hdr’ may result in an unaligned pointer value
[-Werror=address-of-packed-member]
 1011 |  net_copy_u32(&bp->bp_id, &bp_offer->bp_id);

Change the type of the function parameters to void * to avoid the build
error.

net: remove CONFIG_MCAST_TFTP

2019-01-24T17:35:30+00:00

No mainline board enables CONFIG_MCAST_TFTP and there have been
compilation issues with the code for some time. Additionally, it has a
potential buffer underrun issue (reported as a side note in
CVE-2018-18439).

Remove the multicast TFTP code but keep the driver API for the future
addition of IPv6.
