bpftool: Introduce btf c dump sorting

2024-05-18T17:46:16+00:00

Sort bpftool c dump output; aiming to simplify vmlinux.h diffing and forcing more natural type definitions ordering. Definitions are sorted first by their BTF kind ranks, then by their base type name and by their own name. Type ranks Assign ranks to btf kinds (defined in function btf_type_rank) to set next order: 1. Anonymous enums/enums64 2. Named enums/enums64 3. Trivial types typedefs (ints, then floats) 4. Structs/Unions 5. Function prototypes 6. Forward declarations Type rank is set to maximum for unnamed reference types, structs and unions to avoid emitting those types early. They will be emitted as part of the type chain starting with named type. Lexicographical ordering Each type is assigned a sort_name and own_name. sort_name is the resolved name of the final base type for reference types (typedef, pointer, array etc). Sorting by sort_name allows to group typedefs of the same base type. sort_name for non-reference type is the same as own_name. own_name is a direct name of particular type, is used as final sorting step.

bpftool: Address minor issues in bash completion

2024-04-16T15:58:25+00:00

This commit contains a series of clean-ups and fixes for bpftool's bash completion file: - Make sure all local variables are declared as such. - Make sure variables are initialised before being read. - Update ELF section ("maps" -> ".maps") for looking up map names in object files. - Fix call to _init_completion. - Move definition for MAP_TYPE and PROG_TYPE higher up in the scope to avoid defining them multiple times, reuse MAP_TYPE where relevant. - Simplify completion for "duration" keyword in "bpftool prog profile". - Fix completion for "bpftool struct_ops register" and "bpftool link (pin|detach)" where we would repeatedly suggest file names instead of suggesting just one name. - Fix completion for "bpftool iter pin ... map MAP" to account for the "map" keyword. - Add missing "detach" suggestion for "bpftool link".

bpftool: Specify XDP Hints ifname when loading program

2023-05-23T14:55:06+00:00

Add ability to specify a network interface used to resolve XDP hints kfuncs when loading program through bpftool. Usage: bpftool prog load [...] xdpmeta_dev Writing just 'dev ' instead of 'xdpmeta_dev' is a very probable mistake that results in not very descriptive errors, so 'bpftool prog load [...] dev ' syntax becomes deprecated, followed by 'bpftool map create [...] dev ' for consistency. Now, to offload program, execute: bpftool prog load [...] offload_dev To offload map: bpftool map create [...] offload_dev 'dev ' still performs offloading in the commands above, but now triggers a warning and is excluded from bash completion. 'xdpmeta_dev' and 'offload_dev' are mutually exclusive options, because 'xdpmeta_dev' basically makes a program device-bound without loading it onto the said device. For now, offloaded programs cannot use XDP hints [0], but if this changes, using 'offload_dev ' should cover this case.

bpftool: Clean up _bpftool_once_attr() calls in bash completion

2023-04-06T04:27:27+00:00

In bpftool's bash completion file, function _bpftool_once_attr() is able to process multiple arguments. There are a few locations where this function is called multiple times in a row, each time for a single argument; let's pass all arguments instead to minimize the number of function calls required for the completion.

bpftool: Support "opcodes", "linum", "visual" simultaneously

2023-04-06T04:27:27+00:00

When dumping a program, the keywords "opcodes" (for printing the raw opcodes), "linum" (for displaying the filename, line number, column number along with the source code), and "visual" (for generating the control flow graph for translated programs) are mutually exclusive. But there's no reason why they should be. Let's make it possible to pass several of them at once. The "file FILE" option, which makes bpftool output a binary image to a file, remains incompatible with the others.

bpftool: Return an error on prog dumps if both CFG and JSON are required

2023-04-06T04:27:27+00:00

We do not support JSON output for control flow graphs of programs with bpftool. So far, requiring both the CFG and JSON output would result in producing a null JSON object. It makes more sense to raise an error directly when parsing command line arguments and options, so that users know they won't get any output they might expect. If JSON is required for the graph, we leave it to Graphviz instead: # bpftool prog dump xlated visual | dot -Tjson Suggested-by: Eduard Zingerman Signed-off-by: Quentin Monnet Link: https://lore.kernel.org/r/20230405132120.59886-5-quentin@isovalent.com Signed-off-by: Alexei Starovoitov

bpftool: remove support of --legacy option for bpftool
