Currently, prog array map and map of maps are not supported
in bpftool. This patch added the support.
Different from other map types, for prog array map and
map of maps, the key returned bpf_get_next_key() may not
point to a valid value. So for these two map types,
no error will be printed out when such a scenario happens.
The following is the plain and json dump if btf is not available:
$ ./bpftool map dump id 10
key: 08 00 00 00 value: 5c 01 00 00
Found 1 element
$ ./bpftool -jp map dump id 10
[{
"key": ["0x08","0x00","0x00","0x00"
],
"value": ["0x5c","0x01","0x00","0x00"
]
}]
If the BTF is available, the dump looks below:
$ ./bpftool map dump id 2
[{
"key": 0,
"value": 7
}
]
$ ./bpftool -jp map dump id 2
[{
"key": ["0x00","0x00","0x00","0x00"
],
"value": ["0x07","0x00","0x00","0x00"
],
"formatted": {
"key": 0,
"value": 7
}
}]

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
See Documentation/00-INDEX for a list of what is contained in each file.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
