2023-04-01veristat: improve version reportingAndrii Nakryiko
For packaging version of the tool is important, so add a simple way to specify veristat version for upstream mirror at Github.

2023-04-01veristat: relicense veristat.c as dual GPL-2.0-only or BSD-2-Clause licensedAndrii Nakryiko
Dual-license veristat.c to dual GPL-2.0-only or BSD-2-Clause license. This is needed to mirror it to Github to make it convenient for distro packagers to package veristat as a separate package. Veristat grew into a useful tool by itself, and there are already a bunch of users relying on veristat as generic BPF loading and verification helper tool. So making it easy to packagers by providing Github mirror just like we do for bpftool and libbpf is the next step to get veristat into the hands of users. Apart from few typo fixes, I'm the sole contributor to veristat.c so far, so no extra Acks should be needed for relicensing.

2023-03-30selftests: tc-testing: add "depends_on" property to skip testsDavide Caratti
currently, users can skip individual test cases by means of writing "skip": "yes" in the scenario file. Extend this functionality, introducing 'dependsOn': it's optional property like "skip", but the value contains a command (for example, a probe on iproute2 to check if it supports a specific feature). If such property is present, tdc executes that command and skips the test when the return value is non-zero.

2023-03-30selftests: rtnetlink: Fix do_test_address_proto()Petr Machata
This selftest was introduced recently in the commit cited below. It misses several check_err() invocations to actually verify that the previous command succeeded. When these are added, the first one fails, because besides the addresses added by hand, there can be a link-local address added by the kernel. Adjust the check to expect at least three addresses instead of exactly three, and add the missing check_err's. Furthermore, the explanatory comments assume that the address with no protocol is $addr2, when in fact it is $addr3. Update the comments.

2023-03-29veristat: guess and substitue underlying program type for freplace (EXT) progsAndrii Nakryiko
SEC("freplace") (i.e., BPF_PROG_TYPE_EXT) programs are not loadable as is through veristat, as kernel expects actual program's FD during BPF_PROG_LOAD time, which veristat has no way of knowing. Unfortunately, freplace programs are a pretty important class of programs, especially when dealing with XDP chaining solutions, which rely on EXT programs. So let's do our best and teach veristat to try to guess the original program type, based on program's context argument type. And if guessing process succeeds, we manually override freplace/EXT with guessed program type using bpf_program__set_type() setter to increase chances of proper BPF verification. We rely on BTF and maintain a simple lookup table. This process is obviously not 100% bulletproof, as valid program might not use context and thus wouldn't have to specify correct type. Also, __sk_buff is very ambiguous and is the context type across many different program types. We pick BPF_PROG_TYPE_CGROUP_SKB for now, which seems to work fine in practice so far. Similarly, some program types require specifying attach type, and so we pick one out of possible few variants. Best effort at its best. But this makes veristat even more widely applicable.

Also, fix up bpf_prog_test_load() helper in selftests/bpf, which is force-setting program type (even if that's completely unnecessary; this is quite a legacy piece of code), and thus should expect auto-attach to not work, yet one of the tests explicitly relies on auto-attach for testing. Instead, force-set program type only if it differs from the desired one.

This is essentially a backport of iproute2's commit ed54f76484b5 ("json: fix backslash escape typo in jsonw_puts") Also added the stdio.h include in json_writer.h to be able to compile and run the json_writer test as used below). Before this fix: $ gcc -D notused -D TEST -I../../include -o json_writer json_writer.c json_writer.h $ ./json_writer { "Vyatta": { "url": "http://vyatta.com", "downloads": 2000000, "stock": 8.16, "ARGV": [], "empty": [], "NIL": {}, "my_null": null, "special chars": [ "slash": "/", "newline": "\n", "tab": "\t", "ff": "\f", "quote": "\"", "tick": "'", "backslash": "\n" ] } } After: $ gcc -D notused -D TEST -I../../include -o json_writer json_writer.c json_writer.h $ ./json_writer { "Vyatta": { "url": "http://vyatta.com", "downloads": 2000000, "stock": 8.16, "ARGV": [], "empty": [], "NIL": {}, "my_null": null, "special chars": [ "slash": "/", "newline": "\n", "tab": "\t", "ff": "\f", "quote": "\"", "tick": "'", "backslash": "\\" ] } } Signed-off-by: Manu Bretelle <chantr4@gmail.com> Signed-off-by: Andrii Nakryiko <andrii@kernel.org> Reviewed-by: Quentin Monnet <quentin@isovalent.com> Link: https://lore.kernel.org/bpf/20230329073002.2026563-1-chantr4@gmail.com
2023-03-29tracing/user_events: Add ABI self-testBeau Belgrave
Add ABI specific self-test to ensure enablements work in various scenarios such as fork, VM_CLONE, and basic event enable/disable. Ensure ABI contracts/limits are also being upheld, such as bit limits and data size limits.

2023-03-29tools/kvm_stat: use canonical ftrace pathRoss Zwisler
The canonical location for the tracefs filesystem is at /sys/kernel/tracing. But, from Documentation/trace/ftrace.rst: Before 4.1, all ftrace tracing control files were within the debugfs file system, which is typically located at /sys/kernel/debug/tracing. For backward compatibility, when mounting the debugfs file system, the tracefs file system will be automatically mounted at: /sys/kernel/debug/tracing A comment in kvm_stat still refers to this older debugfs path, so let's update it to avoid confusion.

2023-03-29Merge branch 'slab/for-6.4/slob-removal' into slab/for-nextVlastimil Babka
A series by myself to remove CONFIG_SLOB: The SLOB allocator was deprecated in 6.2 and there have been no complaints so far so let's proceed with the removal. Besides the code cleanup, the main immediate benefit will be allowing kfree() family of function to work on kmem_cache_alloc() objects, which was incompatible with SLOB. This includes kfree_rcu() which had no kmem_cache_free_rcu() counterpart yet and now it shouldn't be necessary anymore. Otherwise it's all straightforward removal. After this series, 'git grep slob' or 'git grep SLOB' will have 3 remaining relevant hits in non-mm code: - tomoyo - patch submitted and carried there, doesn't need to wait for this series - skbuff - patch to cleanup now-unnecessary #ifdefs will be posted to netdev after this is merged, as requested to avoid conflicts - ftrace ring_buffer - patch to remove obsolete comment is carried there The rest of 'git grep SLOB' hits are false positives, or intentional (CREDITS, and mm/Kconfig SLUB_TINY description to help those that will happen to migrate later).

2023-03-29macvlan: Add netlink attribute for broadcast cutoffHerbert Xu
Make the broadcast cutoff configurable through netlink. Note that macvlan is weird because there is no central device for us to configure (the lowerdev could be anything). So all the options are duplicated over what could be thousands of child devices. IFLA_MACVLAN_BC_QUEUE_LEN took the approach of taking the maximum of all child device settings. This is unnecessary as we could simply store the option in the port device and take the last child device that gets updated as the value to use.
