[PATCH v5 00/20] UEFI networking support including ipv6 + dhcpv6

From: Robbie Harwood
Subject: [PATCH v5 00/20] UEFI networking support including ipv6 + dhcpv6
Date: Tue, 25 Apr 2023 11:05:11 -0400

This series is an omnibus of changes we carry for networking that has
accumulated since at least 2015.  While most of it did not receive review when
previously posted, one did, so I'm using that as an excuse to call this v4.

At the start, this includes a proposed revert of
ac8a37dda0eabdd80506bebe4fb9a5a9fd227935 ("net/http: Allow use of non-standard
TCP/IP ports").  In 2016, a different approach to this more in keeping with
the way port numbers are typically specified was posted on-list: [1]

At least Debian, Red Hat, SUSE, and Ubuntu have carried it since then, which
means that code in the wild expects this syntax, not the other syntax.
(Others may have as well - I didn't do an exhaustive check - but hopefully
that's enough to convey the point.)

At this point, the division of code between patches is mostly organic.  I've
folded bugfixes into their original commits and moved a few other things
around, so while this doesn't exactly match the division in the rhboot tree,
it does match the code.  At this version, the only code differences are style
adjustments and rebasing around the vlan changes that merged since 2.06.

Changes since last version are to address review from dkiper.  Notably, docs
have been added to the bracketed ipv6 commit, and a new commit has been added
for the grub_netbuff_put() error check.

Be well,

Ian Page Hands (1):
  efinet: Add DHCP proxy support

Javier Martinez Canillas (3):
  efi/http: Enclose literal IPv6 addresses in square brackets
  http: Prepend prefix when the HTTP path is relative
  normal/main: Discover the device to read the config from as a fallback

Mark Salter (1):
  use fw_path prefix when fallback searching for grub config

Michael Chang (6):
  efinet: add structures for PXE messages
  grub.texi: Add net_bootp6 doumentation
  bootp: Process DHCPACK packet during HTTP Boot
  efinet Configure network from UEFI device path
  efinet: set DNS server from UEFI protocol
  Support UEFI networking protocols

Paulo Flabiano Smorigo (1):
  Add fw_path variable to detect config file on efi

Peter Jones (4):
  efinet + bootp: add net_bootp6 command supporting dhcpv6
  efinet: also use the firmware acceleration for http
  efi/http: match protocol+hostname of boot url in root_url
  Try mac/guid/etc before grub.cfg on tftp config files

Robbie Harwood (3):
  Revert "net/http: Allow use of non-standard TCP/IP ports"
  net: read bracketed ipv6 addrs and port numbers
  net/http: check result of grub_netbuff_put() in http_receive()

Stephen Benjamin (1):
  Prepend prefix when HTTP path is relative
