2023-06-10tools: ynl-gen: support / skip pads on the way to kernelJakub Kicinski1-0/+6
Kernel does not have padding requirements for 64b attrs. We can ignore pad attrs. Signed-off-by: Jakub Kicinski <kuba@kernel.org>
2023-06-10tools: ynl-gen: don't pass op_name to RenderInfoJakub Kicinski1-19/+18
The op_name argument is barely used and identical to op.name in all cases. Signed-off-by: Jakub Kicinski <kuba@kernel.org>
2023-06-10tools: ynl-gen: support code gen for eventsJakub Kicinski2-6/+13
Netlink specs support both events and notifications (former can define their own message contents). Plug in missing code to generate types, parsers and include events into notification tables. Signed-off-by: Jakub Kicinski <kuba@kernel.org>
2023-06-10tools: ynl-gen: sanitize notification trackingJakub Kicinski2-43/+27
Don't modify the raw dicts (as loaded from YAML) to pretend that the notify attributes also exist on the ops. This makes the code easier to follow. Signed-off-by: Jakub Kicinski <kuba@kernel.org>

2023-06-10tools: ynl-gen: stop generating common notification handlersJakub Kicinski1-73/+0
Common notification handler was supposed to be a way for the user to parse the notifications from a socket synchronously. I don't think we'll end up using it, ynl_ntf_check() works for all known use cases. Signed-off-by: Jakub Kicinski <kuba@kernel.org>
2023-06-10tools: ynl: regen: regenerate the if laddersJakub Kicinski4-74/+67
Renegate the code to combine } and else and use tmp variable to store type. Signed-off-by: Jakub Kicinski <kuba@kernel.org>
2023-06-10tools: ynl-gen: get attr type outside of if()Jakub Kicinski1-1/+3
Reading attr type with mnl_attr_get_type() for each condition leads to most conditions being longer than 80 chars. Avoid this by reading the type to a variable on the stack. Signed-off-by: Jakub Kicinski <kuba@kernel.org>
2023-06-10tools: ynl-gen: combine else with closing bracketJakub Kicinski1-4/+19
Code gen currently prints: } else if (... This is really ugly. Fix it by delaying printing of closing brackets in anticipation of else coming along. Signed-off-by: Jakub Kicinski <kuba@kernel.org>
2023-06-10tools: ynl-gen: complete the C keyword listJakub Kicinski1-1/+34
C keywords need to be avoided when naming things. Complete the list (ethtool has at least one thing called "auto"). Signed-off-by: Jakub Kicinski <kuba@kernel.org>

2023-06-09tools: ynl: add sample for devlinkJakub Kicinski2-0/+61
Add a sample to show off how to issue basic devlink requests. For added testing issue get requests while walking a dump. $ ./devlink netdevsim/netdevsim1: driver: netdevsim running fw: fw.mgmt: 10.20.30 ... netdevsim/netdevsim2: driver: netdevsim running fw: fw.mgmt: 10.20.30 ...

2023-06-09tools: ynl: generate code for the devlink familyJakub Kicinski3-1/+932
Admittedly the devlink.yaml spec is fairly limitted, it only covers basic device get and info-get ops. That's sufficient to be useful (monitoring FW versions in the fleet). Plus it gives us a chance to exercise deep nesting and directional messaging in YNL. Signed-off-by: Jakub Kicinski <kuba@kernel.org>
2023-06-09tools: ynl-gen: don't generate forward declarations for policies - regenJakub Kicinski3-8/+0

2023-06-09tools: ynl-gen: don't generate forward declarations for policiesJakub Kicinski1-9/+3
Now that all nested types have structs and are sorted topologically there should be no need to generate forward declarations for policies. Signed-off-by: Jakub Kicinski <kuba@kernel.org>
2023-06-09tools: ynl-gen: walk nested types in depthJakub Kicinski1-12/+29
So far we had only created structures for nested types nested directly in messages (second level of attrs so to speak). Walk types in depth to support deeper nesting. Signed-off-by: Jakub Kicinski <kuba@kernel.org>
2023-06-09tools: ynl-gen: inherit struct use infoJakub Kicinski1-0/+8
We only render parse and netlink generation helpers as needed, to avoid generating dead code. Propagate the information from first- and second-layer attribute sets onto all children. Otherwise devlink won't work, it has a lot more levels of nesting. Signed-off-by: Jakub Kicinski <kuba@kernel.org>
2023-06-09tools: ynl-gen: try to sort the types more intelligentlyJakub Kicinski1-2/+24
We need to sort the structures to avoid the need for forward declarations. While at it remove the sort of structs when rendering, it doesn't do anything. Signed-off-by: Jakub Kicinski <kuba@kernel.org>

In preparation for supporting families which use different msg ids to and from the kernel - make sure the ids in op strmap are correct. The map is expected to be used mostly for notifications, don't generate a separate map for the "to kernel" direction. Signed-off-by: Jakub Kicinski <kuba@kernel.org>

2023-06-07tools: ynl-gen: improve unwind on parsing errorsJakub Kicinski1-5/+17
When parsing multi-attr we count the objects and then allocate an array to hold the parsed objects. If an attr space has multiple multi-attr objects, however, if parsing the first array fails we'll leave the object count for the second even tho the second array was never allocated. This may cause crashes when freeing objects on error. Count attributes to a variable on the stack and only set the count in the object once the memory was allocated.

2023-06-06bpf: netfilter: Add BPF_NETFILTER bpf_attach_typeFlorian Westphal3-1/+5
Andrii Nakryiko writes: And we currently don't have an attach type for NETLINK BPF link. Thankfully it's not too late to add it. I see that link_create() in kernel/bpf/syscall.c just bypasses attach_type check. We shouldn't have done that. Instead we need to add BPF_NETLINK attach type to enum bpf_attach_type. And wire all that properly throughout the kernel and libbpf itself. This adds BPF_NETFILTER and uses it.

Since the event-filter-function.tc expects the 'exit_mmap()' directly calls 'kmem_cache_free()', this is vulnerable to code modifications. Choose the target function for the filter test from the sample event data so that it can keep test running correctly even if the caller function name will be changed.

2023-06-03tools: ynl-gen: generate static descriptions of notificationsJakub Kicinski1-10/+42
Notifications may come in at any time. The family must be always ready to parse a random incoming notification. Generate notification table for parsing and tell YNL which request we're processing to distinguish responses from notifications. Signed-off-by: Jakub Kicinski <kuba@kernel.org>
2023-06-03tools: ynl-gen: switch to family structJakub Kicinski1-0/+15
We'll want to store static info about the family soon. Generate a struct. This changes creation from, e.g.: ys = ynl_sock_create("netdev", &yerr); to: ys = ynl_sock_create(&ynl_netdev_family, &yerr); on user's side. Signed-off-by: Jakub Kicinski <kuba@kernel.org>
2023-06-03tools: ynl-gen: generate alloc and free helpers for reqJakub Kicinski1-0/+17
We expect user to allocate requests with calloc(), make things a bit more consistent and provide helpers. Generate free calls, too. Signed-off-by: Jakub Kicinski <kuba@kernel.org>
2023-06-03tools: ynl-gen: move the response reading logic into YNLJakub Kicinski1-36/+27
We generate send() and recv() calls and all msg handling for each operation. It's a lot of repeated code and will only grow with notification handling. Call back to a helper YNL lib instead. Signed-off-by: Jakub Kicinski <kuba@kernel.org>
