net: Fix incorrect DHCP/BOOTP packets on 64-bit systems

2015-04-18T17:11:35+00:00

This commit fixes incorrect DHCP/BOOTP packet layout caused by
'ulong' type size difference on 64 and 32-bit architectures.
It also renames NetReadLong()/NetCopyLong() to
net_read_u32/net_copy_u32() accordingly.

net: cosmetic: Clean up DHCP variables and functions

2015-04-18T17:11:33+00:00

Make a thorough pass through all variables and function names contained
within bootp.c and remove CamelCase and improve naming.

net: cosmetic: Fixup var names related to boot file

2015-04-18T17:11:32+00:00

The variables around the bootfile were inconsistent and used CamelCase.
Update them to make the code more readable.

net: cosmetic: Change IPaddr_t to struct in_addr

2015-04-18T17:11:32+00:00

This patch is simply clean-up to make the IPv4 type that is used match
what Linux uses. It also attempts to move all variables that are IP
addresses use good naming instead of CamelCase. No functional change.

net: BOOTP retry timeout improvements

2014-08-09T15:17:03+00:00

Currently, the BOOTP code sends out its initial request as soon as the
Ethernet driver indicates "link up". If this packet is lost or not
replied to for some reason, the code waits for a 1s timeout before
retrying. For some reason, such early packets are often lost on my
system, so this causes an annoying delay.

To optimize this, modify the BOOTP code to have very short timeouts for
the first packet transmitted, but gradually increase the timeout each
time a timeout occurs. This way, if the first packet is lost, the second
packet is transmitted quite quickly and hence the overall delay is low.
However, if there's still no response, we don't keep spewing out packets
at an insane speed.

It's arguably more correct to try and find out why the first packet is
lost. However, it seems to disappear inside my Ethenet chip; the TX chip
indicates no error during TX (not that it has much in the way of
reporting...), yet wireshark on the RX side doesn't see any packet.
FWIW, I'm using an ASIX USB Ethernet adapter. Perhaps "link up" is
reported too early or based on the wrong condition in HW, and we should
add some fixed extra delay into the driver. However, this would slow down
every link up event even if it ends up not being needed in some cases.
Having BOOTP retry quickly applies the fix/WAR to every possible
Ethernet device, and is quite simple to implement, so seems a better
solution.

net: cosmetic: Rename OPT_SIZE to OPT_FIELD_SIZE

2012-05-23T22:46:17+00:00

Clearer constant name.
Also remove related BOOTP_SIZE which was unused and doesn't take
into account VLAN packets.

net: cosmetic: Un-typedef IP_t

2012-05-23T22:46:00+00:00

Rename IP header related things to IP_UDP. The existing definition
of IP_t includes UDP header, so name it to accurately describe the
structure.

net: Move MAC-seeded rand out of bootp.c

2012-05-23T19:19:22+00:00

Make the MAC-seeded random number generator available to /net in
general.  MAC-seeded rand will be needed by link-local as well, so
give it an interface.
