Add full JSON output support in the dump of 'act_bpf'.
Example using eBPF:
# tc actions flush action bpf
# tc action add action bpf object bpf/action.o section 'action-ok'
# tc -j action list action bpf | jq
[
{
"total acts": 1
},
{
"actions": [
{
"order": 0,
"kind": "bpf",
"bpf_name": "action.o:[action-ok]",
"prog": {
"id": 33,
"tag": "a04f5eef06a7f555",
"jited": 1
},
"control_action": {
"type": "pipe"
},
"index": 1,
"ref": 1,
"bind": 0
}
]
}
]
Example using cBPF:
# tc actions flush action bpf
# a=$(mktemp)
# tcpdump -ddd not ether proto 0x888e >$a
# tc action add action bpf bytecode-file $a index 42
# rm $a
# tc -j action list action bpf | jq
[
{
"total acts": 1
},
{
"actions": [
{
"order": 0,
"kind": "bpf",
"bytecode": {
"length": 4,
"insns": [
{
"code": 40,
"jt": 0,
"jf": 0,
"k": 12
},
{
"code": 21,

"k": 34958
},
{

"jf": 0,
"k": 0
},
{
"code": 6,
"jt": 0,
"jf": 0,
"k": 262144
}
]
},
"control_action": {
"type": "pipe"
},
"index": 42,
"ref": 1,
"bind": 0
}
]
}
]
Tested with:
# ./tdc.py -c bpf

How to compile this.
--------------------
1. libdbm
arpd needs to have the berkeleydb development libraries. For Debian
users this is the package with a name like libdbX.X-dev.
DBM_INCLUDE points to the directory with db_185.h which
is the include file used by arpd to get to the old format Berkeley
database routines. Often this is in the db-devel package.
2. make
The makefile will automatically build a config.mk file which
contains definitions of libraries that may or may not be available
on the system such as: ATM, ELF, MNL, and SELINUX.
3. To make documentation, cd to doc/ directory , then
look at start of Makefile and set correct values for
PAGESIZE=a4 , ie: a4 , letter ... (string)
PAGESPERPAGE=2 , ie: 1 , 2 ... (numeric)
and make there. It assumes, that latex, dvips and psnup
are in your path.
4. This package includes matching sanitized kernel headers because
the build environment may not have up to date versions. See Makefile
if you have special requirements and need to point at different
kernel include files.
