3 years agodoc: FIT image: Clarify format and simplify syntax
Alexandru Gagniuc [Tue, 15 Dec 2020 19:15:43 +0000 (13:15 -0600)]
doc: FIT image: Clarify format and simplify syntax

** Introduction

There are currently four ways to load an OS image with u-boot
  1. SPL -> u-boot -> bootm
  2. SPL blue falcon mode
  3. "Basic" FIT image (CONFIG_LOAD_FIT)
  4. "Full-featured" FIT image (CONFIG_LOAD_FIT_FULL)

These four code paths were developed independently, and share very
little code. (3) and (4), behave very differently, are littered with
special cases. They even have different DTS syntax and properties.

The cause of this divergence is that the FIT format specification
leaves a number of things open to interpretation. The purpose of this
change is to enable the reduction of code size, duplication, and
complexity by updating and streamlining the FIT format.

We are only marginally concerned with backwards compatibility, because
we don't have inter-compatibility. For example, CONFIG_LOAD_FIT is
able to load images that CONFIG_LOAD_FIT_FULL won't. This is a direct
result of the incompatible syntax between the two implementations.

Ideally, these changes would enable "simple" FIT to be a subset of the
"full" fit implementation, and share most code. These changes should
also eliminate the need for falcon mode (although we are not
advocating for the removal of falcon mode at this time).

** Description of changes

 * The "configurations" node is now mandatory

Guessing how to load components based on their "os" and "type" invites
confusion and superfluous heuristics. Instead, require each FIT image
to be explicit on how components should be loaded.

 * Eliminate "ramdisk", "setup", "standalone", and "fpga" properties

Having too many special purpose properties requires special-casing
FIT loading code. When a special property can be handled by another
property, it is redundant.
 - A "ramdisk" is identical to a loadable. Thus ramdisk images should
   be placed under "loadables".
 - A "setup" node can be achieved by using a "kernel" or "firmware"
   property instead.
 - "standalone" is used for u-boot nodes. The correct property to use
   in this case is "firmware".
 - "fpga" is a loadable

 * Prioritize control between "firmware" and "kernel"

"firmware" and "kernel" are special nodes in that control is passed
to the "entry-point" of the image. Both can be present, for example,
an OP-TEE firmware with a linux kernel. When both are present,
control is passed to the "firmware" image.

** Further generalizations (not included herein)

The "firmware" and "kernel" properties could be generalized as a
"next-boot-stage", or similar name. This "next" stage would be special
in that it is both executable, and is the stage that is passed
control. For example, "next-stage" could be an op-tee image, with
linux as a loadable, or a u-boot image.

net: Do not respond to ICMP_ECHO_REQUEST if we do not have an IP address

While doing DHCP the interface IP is set to 0.0.0.0. This causes the
check in net.c on dst_ip to be effectively skipped, and all IP datagrams
are accepted up the IP stack. In the case of an ICMP_ECHO_REQUEST for the
matching MAC address (regardless of destination IP), the result is that
an ICMP_ECHO_REPLY is sent. The source address of the ICMP_ECHO_REPLY is
0.0.0.0, which is an illegal source address.

This can happen in common practice with the following sequence:
DHCP (U-Boot or OS) acquires IP address 10.0.0.1
System reboots
U-Boot starts DHCP and send DHCP DISCOVER
DHCP server decides to OFFER 10.0.0.1 again
  (perhaps because of existing lease or manual configuration)
DHCP server tries to PING 10.0.0.1 to see if anyone is squatting on it
DHCP server still has our MAC address in its ARP table for 10.0.0.1
U-Boot receives PING, and responds with an illegal source address
This may further result in a the DHCP server seeing the response as
  confirmation that someone is squatting on 10.0.0.1, and picking a

Running the start() handler twice without a stop() inbetween completely
breaks communication for some ethernet drivers like fec_mxc.

eth_halt() is called before each eth_init(). Due to the switch to
eth_is_active() in commit 68acb51f442f ("net: Only call halt on a driver
that has been init'ed"), this is not sufficient anymore when netconsole
is active: eth_init_state_only()/eth_halt_state_only() manipulate the
state check that is performed by eth_is_active() without actually
calling into the driver.

The issue can be triggered by starting a network operation (e.g. ping or
tftp) while netconsole is active.

Add an additional "running" flag that reflects the actual state of the
driver and use it to ensure that eth_halt() actually stops the device as
it is supposed to.
