* selftests: devlink: undo changes at the end of resource_testJakub Kicinski2019-11-061-0/+6
| | | | | | | | | | | | The netdevsim object is reused by all the tests, but the resource tests puts it into a broken state (failed reload in a different namespace). Make sure it's fixed up at the end of that test otherwise subsequent tests fail.

* selftests: bpf: log direct file writesJakub Kicinski2019-11-061-6/+14
| | | | | | | | | | | | Recent changes to netdevsim moved creating and destroying devices from netlink to sysfs. The sysfs writes have been implemented as direct writes, without shelling out. This is faster, but leaves no trace in the logs. Add explicit logs to make debugging possible.

| | | | | | | | | | | | | | | | Commit 5bc60de50dfe ("selftests: bpf: Don't try to read files without read permission") got reverted as the fix was not working as expected and real fix came in via 8101e069418d ("selftests: bpf: Skip write only files in debugfs"). When bpf-next got merged into net-next, the test_offload.py had a small conflict. Fix the resolution in ae8a76fb8b5d iby not reintroducing 5bc60de50dfe again.

| * bpf: Add probe_read_{user, kernel} and probe_read_{user, kernel}_str helpersDaniel Borkmann2019-11-021-40/+82
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The current bpf_probe_read() and bpf_probe_read_str() helpers are broken in that they assume they can be used for probing memory access for kernel space addresses /as well as/ user space addresses. However, plain use of probe_kernel_read() for both cases will attempt to always access kernel space address space given access is performed under KERNEL_DS and some archs in-fact have overlapping address spaces where a kernel pointer and user pointer would have the /same/ address value and therefore accessing application memory via bpf_probe_read{,_str}() would read garbage values. Lets fix BPF side by making use of recently added 3d7081822f7f ("uaccess: Add non-pagefault user-space read functions"). Unfortunately, the only way to fix this status quo is to add dedicated bpf_probe_read_{user,kernel}() and bpf_probe_read_{user,kernel}_str() helpers. The bpf_probe_read{,_str}() helpers are kept as-is to retain their current behavior. The two *_user() variants attempt the access always under USER_DS set, the two *_kernel() variants will -EFAULT when accessing user memory if the underlying architecture has non-overlapping address ranges, also avoiding throwing the kernel warning via 00c42373d397 ("x86-64: add warning for non-canonical user access address dereferences").

| * libbpf: Add auto-pinning of maps when loading BPF objectsToke Høiland-Jørgensen2019-11-023-9/+156
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds support to libbpf for setting map pinning information as part of the BTF map declaration, to get automatic map pinning (and reuse) on load. The pinning type currently only supports a single PIN_BY_NAME mode, where each map will be pinned by its name in a path that can be overridden, but defaults to /sys/fs/bpf. Since auto-pinning only does something if any maps actually have a 'pinning' BTF attribute set, we default the new option to enabled, on the assumption that seamless pinning is what most callers want. When a map has a pin_path set at load time, libbpf will compare the map pinned at that location (if any), and if the attributes match, will re-use that map instead of creating a new one. If no existing map is found, the newly created map will instead be pinned at the location. Programs wanting to customise the pinning can override the pinning paths using bpf_map__set_pin_path() before calling bpf_object__load() (including setting it to NULL to disable pinning of a particular map).

| | | | | | | | | | | | | | | | | | | | | | | | | | The existing pin_*() functions all try to create the parent directory before pinning. Move this check into the per-object _pin() functions instead. This ensures consistent behaviour when auto-pinning is added (which doesn't go through the top-level pin_maps() function), at the cost of a few more calls to mkdir().

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Support storing and setting a pin path in struct bpf_map, which can be used for automatic pinning. Also store the pin status so we can avoid attempts to re-pin a map that has already been pinned (or reused from a previous pinning). The behaviour of bpf_object__{un,}pin_maps() is changed so that if it is called with a NULL path argument (which was previously illegal), it will (un)pin only those maps that have a pin_path set.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | When the need_wakeup flag was added to AF_XDP, the format of the XDP_MMAP_OFFSETS getsockopt was extended. Code was added to the kernel to take care of compatibility issues arrising from running applications using any of the two formats. However, libbpf was not extended to take care of the case when the application/libbpf uses the new format but the kernel only supports the old format. This patch adds support in libbpf for parsing the old format, before the need_wakeup flag was added, and emulating a set of static need_wakeup flags that will always work for the application. v2 -> v3: * Incorporated code improvements suggested by Jonathan Lemon v1 -> v2: * Rebased to bpf-next * Rewrote the code as the previous version made you blind Fixes: a4500432c2587cb2a ("libbpf: add support for need_wakeup flag in AF_XDP part") Reported-by: Eloy Degen <degeneloy@gmail.com> Signed-off-by: Magnus Karlsson <magnus.karlsson@intel.com> Signed-off-by: Alexei Starovoitov <ast@kernel.org> Acked-by: Jonathan Lemon <jonathan.lemon@gmail.com> Link: https://lore.kernel.org/bpf/1571995035-21889-1-git-send-email-magnus.karlsson@intel.com
