Note that this undoes the changes of commit cf6d4535cc4c ("x86:
emulation: Disable bloblist for now") as that was intended only for the
release due to time.

net: lwip: remove superfluous newline at tftp help text

The help text has a newline at the end which will lead to an empty
line after the tftpboot when printing the help overview. Remove it.

net: lwip: add support for built-in root certificates

2025-03-11T13:16:03+00:00

Introduce Kconfig symbols WGET_BUILTIN_CACERT and
WGET_BUILTIN_CACERT_PATH to provide root certificates at build time.

Usage example:

 wget -O cacert.crt https://cacerts.digicert.com/DigiCertTLSECCP384RootG5.crt
 make qemu_arm64_lwip_defconfig
 echo CONFIG_WGET_BUILTIN_CACERT=y >>.config
 echo CONFIG_WGET_BUILTIN_CACERT_PATH=cacert.crt >>.config
 make olddefconfig
 make -j$(nproc) CROSS_COMPILE="ccache aarch64-linux-gnu-"
 qemu-system-aarch64 -M virt -nographic -cpu max \
    -object rng-random,id=rng0,filename=/dev/urandom \
    -device virtio-rng-pci,rng=rng0 -bios u-boot.bin
 => dhcp
 # HTTPS transfer using the builtin CA certificates
 => wget https://digicert-tls-ecc-p384-root-g5.chain-demos.digicert.com/
 1867 bytes transferred in 1 ms (1.8 MiB/s)
 Bytes transferred = 1867 (74b hex)

net: lwip: extend wget to support CA (root) certificates

2025-03-11T13:16:03+00:00

Add the "cacert" (Certification Authority certificates) subcommand to
wget to pass root certificates to the code handling the HTTPS protocol.
The subcommand is enabled by the WGET_CACERT Kconfig symbol.

Usage example:

 => dhcp
 # Download some root certificates (note: not authenticated!)
 => wget https://cacerts.digicert.com/DigiCertTLSECCP384RootG5.crt
 # Provide root certificates
 => wget cacert $fileaddr $filesize
 # Enforce verification (it is optional by default)
 => wget cacert required
 # Forget the root certificates
 => wget cacert 0 0
 # Disable verification
 => wget cacert none

net: lwip: add wget command

2024-10-16T17:11:56+00:00

Add support for the wget command with NET_LWIP. The command normally
expects a URL: wget [loadaddr] url, but it also accepts the legacy
syntax: wget [loadaddr] [server:]file.
The server IP may alternatively be supplied via ${httpserverip} which
has higher priority than ${serverip}.

Based on code initially developed by Maxim U.
