Merge branch 'bpftool-flow-dissector'
Stanislav Fomichev says:
====================
v5 changes:
* FILE -> PATH for load/loadall (can be either file or directory now)
* simpler implementation for __bpf_program__pin_name
* removed p_err for REQ_ARGS checks
* parse_atach_detach_args -> parse_attach_detach_args
* for -> while in bpf_object__pin_{programs,maps} recovery
v4 changes:
* addressed another round of comments/style issues from Jakub Kicinski &
Quentin Monnet (thanks!)
* implemented bpf_object__pin_maps and bpf_object__pin_programs helpers and
used them in bpf_program__pin
* added new pin_name to bpf_program so bpf_program__pin
works with sections that contain '/'
* moved *loadall* command implementation into a separate patch
* added patch that implements *pinmaps* to pin maps when doing
load/loadall
v3 changes:
* (maybe) better cleanup for partial failure in bpf_object__pin
* added special case in bpf_program__pin for programs with single
instances
v2 changes:
* addressed comments/style issues from Jakub Kicinski & Quentin Monnet
* removed logic that populates jump table
* added cleanup for partial failure in bpf_object__pin
This patch series adds support for loading and attaching flow dissector
programs from the bpftool:
* first patch fixes flow dissector section name in the selftests (so
libbpf auto-detection works)
* second patch adds proper cleanup to bpf_object__pin, parts of which are now
being used to attach all flow dissector progs/maps
* third patch adds special case in bpf_program__pin for programs with
single instances (we don't create <prog>/0 pin anymore, just <prog>)
* forth patch adds pin_name to the bpf_program struct
which is now used as a pin name in bpf_program__pin et al
* fifth patch adds *loadall* command that pins all programs, not just
the first one
* sixth patch adds *pinmaps* argument to load/loadall to let users pin
all maps of the obj file
* seventh patch adds actual flow_dissector support to the bpftool and
an example
