2019-10-07samples: pktgen: make variable consistent with optionDaniel T. Lee
This commit changes variable names that can cause confusion. For example, variable DST_MIN is quite confusing since the keyword 'udp_dst_min' and keyword 'dst_min' is used with pg_ctrl. On the following commit, 'dst_min' will be used to set destination IP, and the existing variable name DST_MIN should be changed. Variable names are matched to the exact keyword used with pg_ctrl.

2019-10-06Merge branch 'autogen-bpf-helpers'Alexei Starovoitov
Andrii Nakryiko says: ==================== This patch set adds ability to auto-generate list of BPF helper definitions. It relies on existing scripts/bpf_helpers_doc.py and include/uapi/linux/bpf.h having a well-defined set of comments. bpf_helper_defs.h contains all BPF helper signatures which stay in sync with latest bpf.h UAPI. This auto-generated header is included from bpf_helpers.h, while all previously hand-written BPF helper definitions are simultaneously removed in patch #3. The end result is less manually maintained and redundant boilerplate code, while also more consistent and well-documented set of BPF helpers. Generated helper definitions are completely independent from a specific bpf.h on a target system, because it doesn't use BPF_FUNC_xxx enums. v3->v4: - instead of libbpf's Makefile, integrate with selftest/bpf's Makefile (Alexei); v2->v3: - delete bpf_helper_defs.h properly (Alexei); v1->v2: - add bpf_helper_defs.h to .gitignore and `make clean` (Alexei). ==================== Signed-off-by: Alexei Starovoitov <ast@kernel.org>

2019-10-06Merge branch 'mlxsw-Query-number-of-modules-from-firmware'David S. Miller
Ido Schimmel says: ==================== mlxsw: Query number of modules from firmware Vadim says: The patchset adds support for a new field "num_of_modules" of Management General Peripheral Information Register (MGPIR), providing the maximum number of QSFP modules, which can be supported by the system. It allows to obtain the number of QSFP modules directly from this field, as a static data, instead of old method of getting this info through "network port to QSFP module" mapping. With the old method, in case of port dynamic re-configuration some modules can logically "disappear" as a result of port split operations, which can cause some modules to appear missing. Such scenario can happen on a system equipped with a BMC card, while PCI chip driver at host CPU side can perform some ports "split" or "unsplit" operations, while BMC side I2C chip driver reads the "port-to-module" mapping. Add common API for FW "minor" and "subminor" versions validation and share it between PCI and I2C based drivers. Add FW version validation for "minimal" driver, because use of new field "num_of_modules" in MGPIR register is not backward compatible. ==================== Signed-off-by: David S.

2019-10-05Merge branch 'libbpf-api'Alexei Starovoitov
Andrii Nakryiko says: ==================== Add bpf_object__open_file() and bpf_object__open_mem() APIs that use a new approach to providing future-proof non-ABI-breaking API changes. It relies on APIs accepting optional self-describing "opts" struct, containing its own size, filled out and provided by potentially outdated (as well as newer-than-libbpf) user application. A set of internal helper macros (OPTS_VALID, OPTS_HAS, and OPTS_GET) streamline and simplify a graceful handling forward and backward compatibility for user applications dynamically linked against different versions of libbpf shared library. Users of libbpf are provided with convenience macro LIBBPF_OPTS that takes care of populating correct structure size and zero-initializes options struct, which helps avoid obscure issues of unitialized padding. Uninitialized padding in a struct might turn into garbage-populated new fields understood by future versions of libbpf. Patch #1 removes enforcement of kern_version in libbpf and always populates correct one on behalf of users. Patch #2 defines necessary infrastructure for options and two new open APIs relying on it. Patch #3 fixes bug in bpf_object__name(). Patch #4 switches two of test_progs' tests to use new APIs as a validation that they work as expected. v2->v3: - fix LIBBPF_OPTS() to ensure zero-initialization of padded bytes; - pass through name override and relaxed maps flag for open_file() (Toke); - fix bpf_object__name() to actually return object name; - don't bother parsing and verifying version section (John); v1->v2: - use better approach for tracking last field in opts struct; - convert few tests to new APIs for validation; - fix bug with using offsetof(last_field) instead of offsetofend(last_field). ==================== Signed-off-by: Alexei Starovoitov <ast@kernel.org>

2019-10-05libbpf: add bpf_object__open_{file, mem} w/ extensible optsAndrii Nakryiko
Add new set of bpf_object__open APIs using new approach to optional parameters extensibility allowing simpler ABI compatibility approach. This patch demonstrates an approach to implementing libbpf APIs that makes it easy to extend existing APIs with extra optional parameters in such a way, that ABI compatibility is preserved without having to do symbol versioning and generating lots of boilerplate code to handle it. To facilitate succinct code for working with options, add OPTS_VALID, OPTS_HAS, and OPTS_GET macros that hide all the NULL, size, and zero checks. Additionally, newly added libbpf APIs are encouraged to follow similar pattern of having all mandatory parameters as formal function parameters and always have optional (NULL-able) xxx_opts struct, which should always have real struct size as a first field and the rest would be optional parameters added over time, which tune the behavior of existing API, if specified by user.

2019-10-05libbpf: stop enforcing kern_version, populate it for usersAndrii Nakryiko
Kernel version enforcement for kprobes/kretprobes was removed from 5.0 kernel in 6c4fc209fcf9 ("bpf: remove useless version check for prog load"). Since then, BPF programs were specifying SEC("version") just to please libbpf. We should stop enforcing this in libbpf, if even kernel doesn't care. Furthermore, libbpf now will pre-populate current kernel version of the host system, in case we are still running on old kernel. This patch also removes __bpf_object__open_xattr from libbpf.h, as nothing in libbpf is relying on having it in that header. That function was never exported as LIBBPF_API and even name suggests its internal version. So this should be safe to remove, as it doesn't break ABI.

Due to a quirky C syntax of declaring pointers to array or function prototype, existing __type() macro doesn't work with map key/value types that are array or function prototype. One has to create a typedef first and use it to specify key/value type for a BPF map. By using typeof(), pointer to type is now handled uniformly for all kinds of types.

Jakub Kicinski says: ==================== net/tls: add ctrl path tracing and statistics This set adds trace events related to TLS offload and basic MIB stats for TLS. First patch contains the TLS offload related trace points. Those are helpful in troubleshooting offload issues, especially around the resync paths. Second patch adds a tracepoint to the fastpath of device offload, it's separated out in case there will be objections to adding fast path tracepoints. Again, it's quite useful for debugging offload issues. Next four patches add MIB statistics. The statistics are implemented as per-cpu per-netns counters. Since there are currently no fast path statistics we could move to atomic variables. Per-CPU seem more common. Most basic statistics are number of created and live sessions, broken out to offloaded and non-offloaded. Users seem to like those a lot. Next there is a statistic for decryption errors. These are primarily useful for device offload debug, in normal deployments decryption errors should not be common. Last but not least a counter for device RX resync. ==================== Reviewed-by: Simon Horman <simon.horman@netronome.com> Signed-off-by: David S. Miller <davem@davemloft.net>
