2022-11-10devlink: Fix warning when unregistering a portIdo Schimmel
When a devlink port is unregistered, its type is expected to be unset or otherwise a WARNING is generated [1]. This was supposed to be handled by cited commit by clearing the type upon 'NETDEV_PRE_UNINIT'. The assumption was that no other events can be generated for the netdev after this event, but this proved to be wrong. After the event is generated, netdev_wait_allrefs_any() will rebroadcast a 'NETDEV_UNREGISTER' until the netdev's reference count drops to 1. This causes devlink to set the port type back to Ethernet. Fix by only setting and clearing the port type upon 'NETDEV_POST_INIT' and 'NETDEV_PRE_UNINIT', respectively. For all other events, preserve the port type.

2022-11-10ethtool: ethtool_get_drvinfo: populate drvinfo fields even if callback exitsVincent Mailhol
If ethtool_ops::get_drvinfo() callback isn't set, ethtool_get_drvinfo() will fill the ethtool_drvinfo::name and ethtool_drvinfo::bus_info fields. However, if the driver provides the callback function, those two fields are not touched. This means that the driver has to fill these itself. Allow the driver to leave those two fields empty and populate them in such case. This way, the driver can rely on the default values for the name and the bus_info. If the driver provides values, do nothing.

The root cause is in commit 2e0de6366ac16 changed the control logic dropping this case, if (priv->_xdp_prog) { err = veth_enable_xdp(dev); if (err) return err; - } else if (veth_gro_requested(dev)) { + /* refer to the logic in veth_xdp_set() */ + if (!rtnl_dereference(peer_rq->napi)) { + err = veth_napi_enable(peer); + if (err) + return err; + } so that now veth_napi_enable is called if the peer has not yet initialiazed its peer_rq->napi. The issue is this will happen even if the NIC is not up. Then in veth_enable_xdp just above we have similar path, veth_enable_xdp napi_already_on = (dev->flags & IFF_UP) && rcu_access_pointer(rq->napi) err = veth_enable_xdp_range(dev, 0, dev->real_num_rx_queues, napi_already_on); The trouble is an xdp prog is assigned before bringing the device up each of the veth_open path will enable the peers xdp napi structs. But then when we bring the peer up it will similar try to enable again because from veth_open the IFF_UP flag is not set until after the op in __dev_open so we believe napi_alread_on = false. To fix this just drop the IFF_UP test and rely on checking if the napi struct is enabled. This also matches the peer check in veth_xdp for disabling. To reproduce run ./test_xdp_meta.sh I found adding Cilium/Tetragon tests for XDP.

When showing the result of a test group, if one of the subtests was skipped, while still having passing subtests, the group result was marked as SKIP.

With this change, only if all of the subtests were skipped, the group test is marked as SKIP. When only some of the subtests are skipped, a more detailed result is given, stating how many of the subtests were skipped.

2022-11-09Merge branch 'libbpf: Resolve unambigous forward declarations'Andrii Nakryiko
Eduard Zingerman says: ==================== The patch-set is consists of the following parts: - An update for libbpf's hashmap interface from void* -> void* to a polymorphic one, allowing to use both long and void* keys and values w/o additional casts. Interface functions are hidden behind auxiliary macro that add casts as necessary. This simplifies many use cases in libbpf as hashmaps there are mostly integer to integer and required awkward looking incantations like `(void *)(long)off` previously. Also includes updates for perf as it copies map implementation from libbpf. - A change to `lib/bpf/btf.c:btf__dedup` that adds a new pass named "Resolve unambiguous forward declaration". This pass builds a hashmap `name_off -> uniquely named struct or union` and uses it to replace FWD types by structs or unions. This is necessary for corner cases when FWD is not used as a part of some struct or union definition de-duplicated by `btf_dedup_struct_types`. The goal of the patch-set is to resolve forward declarations that don't take part in type graphs comparisons if declaration name is unambiguous. Example: CU #1: struct foo; // standalone forward declaration struct foo *some_global; CU #2: struct foo { int x; }; struct foo *another_global; Currently the de-duplicated BTF for this example looks as follows: [1] STRUCT 'foo' size=4 vlen=1 ... [2] INT 'int' size=4 ... [3] PTR '(anon)' type_id=1 [4] FWD 'foo' fwd_kind=struct [5] PTR '(anon)' type_id=4 The goal of this patch-set is to simplify it as follows: [1] STRUCT 'foo' size=4 vlen=1 'x' type_id=2 bits_offset=0 [2] INT 'int' size=4 bits_offset=0 nr_bits=32 encoding=SIGNED [3] PTR '(anon)' type_id=1 For defconfig kernel with BTF enabled this removes 63 forward declarations. For allmodconfig kernel with BTF enabled this removes ~5K out of ~21K forward declarations in ko objects. This unlocks some additional de-duplication in ko objects, but impact is tiny: ~13K less BTF ids out of ~2M. Changelog: v3 -> v4 Changes suggested by Andrii: - hashmap interface rework to allow use of integer and pointer keys an values w/o casts as suggested in [1]. v2 -> v3 Changes suggested by Andrii: - perf's util/hashtable.{c,h} are synchronized with libbpf implementation, perf's source code updated accordingly; - changes to libbpf, bpf selftests and perf are combined in a single patch to simplify bisecting; - hashtable interface updated to be long -> long instead of uintptr_t -> uintptr_t; - btf_dedup_resolve_fwds updated to correctly use IS_ERR / PTR_ERR macro; - test cases for btf_dedup_resolve_fwds are updated for better clarity. v1 -> v2 - Style fixes in btf_dedup_resolve_fwd and btf_dedup_resolve_fwds as suggested by Alan.

2022-11-09libbpf: Resolve unambigous forward declarationsEduard Zingerman
Resolve forward declarations that don't take part in type graphs comparisons if declaration name is unambiguous. Example: CU #1: struct foo; // standalone forward declaration struct foo *some_global; CU #2: struct foo { int x; }; struct foo *another_global; The `struct foo` from CU #1 is not a part of any definition that is compared against another definition while `btf_dedup_struct_types` processes structural types. The the BTF after `btf_dedup_struct_types` the BTF looks as follows: [1] STRUCT 'foo' size=4 vlen=1 ... [2] INT 'int' size=4 ... [3] PTR '(anon)' type_id=1 [4] FWD 'foo' fwd_kind=struct [5] PTR '(anon)' type_id=4 This commit adds a new pass `btf_dedup_resolve_fwds`, that maps such forward declarations to structs or unions with identical name in case if the name is not ambiguous. The pass is positioned before `btf_dedup_ref_types` so that types [3] and [5] could be merged as a same type after [1] and [4] are merged. The final result for the example above looks as follows: [1] STRUCT 'foo' size=4 vlen=1 'x' type_id=2 bits_offset=0 [2] INT 'int' size=4 bits_offset=0 nr_bits=32 encoding=SIGNED [3] PTR '(anon)' type_id=1 For defconfig kernel with BTF enabled this removes 63 forward declarations. Examples of removed declarations: `pt_regs`, `in6_addr`. The running time of `btf__dedup` function is increased by about 3%.

2022-11-09libbpf: Hashmap interface update to allow both long and void* keys/valuesEduard Zingerman
An update for libbpf's hashmap interface from void* -> void* to a polymorphic one, allowing both long and void* keys and values. This simplifies many use cases in libbpf as hashmaps there are mostly integer to integer. Perf copies hashmap implementation from libbpf and has to be updated as well. Changes to libbpf, selftests/bpf and perf are packed as a single commit to avoid compilation issues with any future bisect. Polymorphic interface is acheived by hiding hashmap interface functions behind auxiliary macros that take care of necessary type casts, for example: #define hashmap_cast_ptr(p) \ ({ \ _Static_assert((p) == NULL || sizeof(*(p)) == sizeof(long),\ #p " pointee should be a long-sized integer or a pointer"); \ (long *)(p); \ }) bool hashmap_find(const struct hashmap *map, long key, long *value); #define hashmap__find(map, key, value) \ hashmap_find((map), (long)(key), hashmap_cast_ptr(value)) - hashmap__find macro casts key and value parameters to long and long* respectively - hashmap_cast_ptr ensures that value pointer points to a memory of appropriate size. This hack was suggested by Andrii Nakryiko in [1]. This is a follow up for [2].
