fastboot: Add support for 'reboot fastboot' command

2020-09-01T12:47:43+00:00

Android 10 adds support for dynamic partitions and in order to support
this userspace fastboot must be used[1]. New tool fastbootd is
included into recovery.

Userspace fastboot works from recovery and is launched if:
1) - Dynamic partitioning is enabled
2) - Boot control block has 'boot-fastboot' value into command field
The bootloader is expected to load and boot into the recovery image
upon seeing boot-fastboot in the BCB command. Recovery then parses the
BCB message and switches to fastbootd mode[2].

Please note that boot script is expected to handle 'boot-fastboot'
command in BCB and load into recovery mode.

Bootloader must support 'reboot fastboot' command which should reboot
device into userspace fastboot to accomodate those changes[3].

Another command that bootloader must support[3] is 'reboot recovery'. This
command should simply reboot device into recovery mode.

Reset the stored ping IP address before entering a netloop with different
protocol to ensure that it won't be interrupted by the received
correct ICMP_ECHO_REPLY packet.

net: tftp: Add client support for RFC 7440

2020-08-05T03:30:02+00:00

Add support for RFC 7440: "TFTP Windowsize Option".

This optional feature allows the client and server
to negotiate a window size of consecutive blocks to send as an
alternative for replacing the single-block lockstep schema.

windowsize can be defined statically during compilation by
setting CONFIG_TFTP_WINDOWSIZE, or defined in runtime by
setting an environment variable: "tftpwindowsize"
If not defined, the windowsize is set to 1, meaning that it
behaves as it was never defined.

Choosing the appropriate windowsize depends on the specific
network topology, underlying NIC.
You should test various windowsize scenarios and see which
best work for you.

Setting a windowsize too big can actually decreases performance.

treewide: convert bd_t to struct bd_info by coccinelle

2020-07-17T13:30:13+00:00

The Linux coding style guide (Documentation/process/coding-style.rst)
clearly says:

  It's a **mistake** to use typedef for structures and pointers.

Besides, using typedef for structures is annoying when you try to make
headers self-contained.

Let's say you have the following function declaration in a header:

  void foo(bd_t *bd);

This is not self-contained since bd_t is not defined.

To tell the compiler what 'bd_t' is, you need to include 

  #include 
  void foo(bd_t *bd);

Then, the include direcective pulls in more bloat needlessly.

If you use 'struct bd_info' instead, it is enough to put a forward
declaration as follows:

  struct bd_info;
  void foo(struct bd_info *bd);

Right, typedef'ing bd_t is a mistake.

I used coccinelle to generate this commit.

The semantic patch that makes this change is as follows:

  
  @@
  typedef bd_t;
  @@
  -bd_t
  +struct bd_info

net: dm: Remove warning about EEPROM provided MAC address

2020-07-07T22:23:48+00:00

Similar to patch 821fec0ceb3e ("net: remove scary warning about EEPROM
provided MAC address") this removes the somewhat awkward "warning" on
boards using DM_ETH:
In many parts of the computing world having a unique MAC address
sitting in some on-NIC storage is considered the normal case.

If there is a properly provided MAC address (either from ROM or from DT),
remove the warning to not scare the user unnecessarily.

net: move random_port() to dns

The random_port() routine is not used anywhere else. Make it local to
dns.c to reduce code clutter, and shrink generated code a little.

net: tftp: fix progress marker for file transfer

2020-06-12T17:17:23+00:00

During packet sequence number wraparound the show_block_marker() API was
not called, as a result the progress marker doesn't stay within column
boundary. Use position in file instead of sequence number to align the
marker.
