2022-09-21bpftool: Fix wrong cgroup attach flags being assigned to effective progsPu Lehui1-5/+49
When root-cgroup attach multi progs and sub-cgroup attach a override prog, bpftool will display incorrectly for the attach flags of the sub-cgroup’s effective progs: $ bpftool cgroup tree /sys/fs/cgroup effective CgroupPath ID AttachType AttachFlags Name /sys/fs/cgroup 6 cgroup_sysctl multi sysctl_tcp_mem 13 cgroup_sysctl multi sysctl_tcp_mem /sys/fs/cgroup/cg1 20 cgroup_sysctl override sysctl_tcp_mem 6 cgroup_sysctl override sysctl_tcp_mem <- wrong 13 cgroup_sysctl override sysctl_tcp_mem <- wrong /sys/fs/cgroup/cg1/cg2 20 cgroup_sysctl sysctl_tcp_mem 6 cgroup_sysctl sysctl_tcp_mem 13 cgroup_sysctl sysctl_tcp_mem Attach flags is only valid for attached progs of this layer cgroup, but not for effective progs. For querying with EFFECTIVE flags, exporting attach flags does not make sense. So let's remove the AttachFlags field and the associated logic. After this patch, the above effective cgroup tree will show as bellow: $ bpftool cgroup tree /sys/fs/cgroup effective CgroupPath ID AttachType Name /sys/fs/cgroup 6 cgroup_sysctl sysctl_tcp_mem 13 cgroup_sysctl sysctl_tcp_mem /sys/fs/cgroup/cg1 20 cgroup_sysctl sysctl_tcp_mem 6 cgroup_sysctl sysctl_tcp_mem 13 cgroup_sysctl sysctl_tcp_mem /sys/fs/cgroup/cg1/cg2 20 cgroup_sysctl sysctl_tcp_mem 6 cgroup_sysctl sysctl_tcp_mem 13 cgroup_sysctl sysctl_tcp_mem Fixes: b79c9fc9551b ("bpf: implement BPF_PROG_QUERY for BPF_LSM_CGROUP") Fixes: a98bf57391a2 ("tools: bpftool: add support for reporting the effective cgroup progs") Signed-off-by: Pu Lehui <pulehui@huawei.com> Link: https://lore.kernel.org/r/20220921104604.2340580-3-pulehui@huaweicloud.com Signed-off-by: Martin KaFai Lau <martin.lau@kernel.org>

2022-06-02bpftool: Use libbpf_bpf_attach_type_strDaniel Müller1-17/+36
This change switches bpftool over to using the recently introduced libbpf_bpf_attach_type_str function instead of maintaining its own string representation for the bpf_attach_type enum. Note that contrary to other enum types, the variant names that bpftool maps bpf_attach_type to do not adhere a simple to follow rule. With bpf_prog_type, for example, the textual representation can easily be inferred by stripping the BPF_PROG_TYPE_ prefix and lowercasing the remaining string. bpf_attach_type violates this rule for various variants. We decided to fix up this deficiency with this change, meaning that bpftool uses the same textual representations as libbpf. Supporting tests, completion scripts, and man pages have been adjusted accordingly. However, we did add support for accepting (the now undocumented) original attach type names when they are provided by users. For the test (test_bpftool_synctypes.py), I have removed the enum representation checks, because we no longer mirror the various enum variant names in bpftool source code. For the man page, help text, and completion script checks we are now using enum definitions from uapi/linux/bpf.h as the source of truth directly.

2022-01-19bpftool: Adding support for BTF program namesRaman Shukhau1-2/+4
`bpftool prog list` and other bpftool subcommands that show BPF program names currently get them from bpf_prog_info.name. That field is limited to 16 (BPF_OBJ_NAME_LEN) chars which leads to truncated names since many progs have much longer names. The idea of this change is to improve all bpftool commands that output prog name so that bpftool uses info from BTF to print program names if available. It tries bpf_prog_info.name first and fall back to btf only if the name is suspected to be truncated (has 15 chars length). Right now `bpftool p show id <id>` returns capped prog name <id>: kprobe name example_cap_cap tag 712e... ... With this change it would return <id>: kprobe name example_cap_capable tag 712e... ... Note, other commands that print prog names (e.g. "bpftool cgroup tree") are also addressed in this change.

2021-07-30tools: bpftool: Update and synchronise option list in doc and help msgQuentin Monnet1-1/+2
All bpftool commands support the options for JSON output and debug from libbpf. In addition, some commands support additional options corresponding to specific use cases. The list of options described in the man pages for the different commands are not always accurate. The messages for interactive help are mostly limited to HELP_SPEC_OPTIONS, and are even less representative of the actual set of options supported for the commands. Let's update the lists: - HELP_SPEC_OPTIONS is modified to contain the "default" options (JSON and debug), and to be extensible (no ending curly bracket). - All commands use HELP_SPEC_OPTIONS in their help message, and then complete the list with their specific options. - The lists of options in the man pages are updated. - The formatting of the list for bpftool.rst is adjusted to match formatting for the other man pages. This is for consistency, and also because it will be helpful in a future patch to automatically check that the files are synchronised.

Let's reuse this for all other help functions. We can remove up to thirty arguments for the "bpftool map" help message. - Harmonise all functions, e.g. use ending quotes-comma on a separate line.

2019-07-30tools: bpftool: add support for reporting the effective cgroup progsJakub Kicinski1-28/+55
Takshak said in the original submission: With different bpf attach_flags available to attach bpf programs specially with BPF_F_ALLOW_OVERRIDE and BPF_F_ALLOW_MULTI, the list of effective bpf-programs available to any sub-cgroups really needs to be available for easy debugging. Using BPF_F_QUERY_EFFECTIVE flag, one can get the list of not only attached bpf-programs to a cgroup but also the inherited ones from parent cgroup. So a new option is introduced to use BPF_F_QUERY_EFFECTIVE query flag here to list all the effective bpf-programs available for execution at a specified cgroup. Reused modified test program test_cgroup_attach from tools/testing/selftests/bpf: # ./test_cgroup_attach With old bpftool: # bpftool cgroup show /sys/fs/cgroup/cgroup-test-work-dir/cg1/ ID AttachType AttachFlags Name 271 egress multi pkt_cntr_1 272 egress multi pkt_cntr_2 Attached new program pkt_cntr_4 in cg2 gives following: # bpftool cgroup show /sys/fs/cgroup/cgroup-test-work-dir/cg1/cg2 ID AttachType AttachFlags Name 273 egress override pkt_cntr_4 And with new "effective" option it shows all effective programs for cg2: # bpftool cgroup show /sys/fs/cgroup/cgroup-test-work-dir/cg1/cg2 effective ID AttachType AttachFlags Name 273 egress override pkt_cntr_4 271 egress override pkt_cntr_1 272 egress override pkt_cntr_2 Compared to original submission use a local flag instead of global option. We need to clear query_flags on every command, in case batch mode wants to use varying settings. v2: (Takshak) - forbid duplicated flags; - fix cgroup path freeing.

2019-04-16tools: bpftool: reset errno for "bpftool cgroup tree"Quentin Monnet1-0/+7
When trying to dump the tree of all cgroups under a given root node, bpftool attempts to query programs of all available attach types. Some of those attach types do not support queries, therefore several of the calls are actually expected to fail. Those calls set errno to EINVAL, which has no consequence for dumping the rest of the tree. It does have consequences however if errno is inspected at a later time. For example, bpftool batch mode relies on errno to determine whether a command has succeeded, and whether it should carry on with the next command. Setting errno to EINVAL when everything worked as expected would therefore make such command fail: # echo 'cgroup tree \n net show' | \ bpftool batch file - To improve this, reset errno when its value is EINVAL after attempting to show programs for all existing attach types in do_show_tree_fn().
