Provide functions to create selftests dedicated to TCP-AO. They can run in parallel, as they use temporary net namespaces. They can be very specific to the feature being tested. This will allow to create a lot of TCP-AO tests, without complicating one binary with many --options and to create scenarios, that are hard to put in bash script that uses one binary. Signed-off-by:

phylink_parse_mode() populates all possible supported link modes for a given phy_interface_t, for the case where a phylib phy may be absent and we can't retrieve the supported link modes from that. Russell points out that since the introduction of the generic validation helpers phylink_get_capabilities() and phylink_caps_to_linkmodes(), we can rewrite this procedure to populate the pl->supported mask, so that instead of spelling out the link modes, we derive an intermediary mac_capabilities bit field, and we convert that to the equivalent link modes.

In commit 1580ab63 ("tcp/dccp: better use of ephemeral ports in connect()") we added an heuristic to select even ports for connect() and odd ports for bind(). This was nice because no applications changes were needed. But it added more costs when all even ports are in use, when there are few listeners and many active connections. Since then, IP_LOCAL_PORT_RANGE has been added to permit an application to partition ephemeral port range at will. This patch extends the idea so that if IP_LOCAL_PORT_RANGE is set on a socket before accept(), port selection no longer favors even ports. This means that connect() can find a suitable source port faster, and applications can use a different split between connect() and bind() users. This should give more entropy to Toeplitz hash used in RSS: Using even ports was wasting one bit from the 16bit sport. A similar change can be done in inet_csk_find_open_port() if needed.

Op's "attributes" list is a workaround for families with a single attr set. We don't want to render a single huge request structure, the same for each op since we know that most ops accept only a small set of attributes. "Attributes" list lets us narrow down the attributes to what op acctually pays attention to. It doesn't make sense to put names of fixed headers in there. They are not "attributes" and we can't really narrow down the struct members. Remove the fixed header fields from attrs for ovs families in preparation for C codegen support. Reviewed-by:

Tony Nguyen says: ==================== add v2 FW logging for ice driver Paul Stillwell says: Firmware (FW) log support was added to the ice driver, but that version is no longer supported. There is a newer version of FW logging (v2) that adds more control knobs to get the exact data out of the FW for debugging. The interface for FW logging is debugfs. This was chosen based on discussions here: https://lore.kernel.org/netdev/20230214180712.53fc8ba2@kernel.org/ and https://lore.kernel.org/netdev/20231012164033.1069fb4b@kernel.org/ We talked about using devlink in a variety of ways, but none of those options made any sense for the way the FW reports data. We briefly talked about using ethtool, but that seemed to go by the wayside. Ultimately it seems like using debugfs is the way to go so re-implement the code to use that. FW logging is across all the PFs on the device so restrict the commands to only PF0. If the device supports FW logging then a directory named 'fwlog' will be created under '/sys/kernel/debug/ice/<pci_dev>'. A variety of files will be created to manage the behavior of logging. The following files will be created: - modules/<module> - nr_messages - enable - log_size - data where modules/<module> is used to read/write the log level for a specific module nr_messages is used to determine how many events should be in each message sent to the driver enable is used to start/stop FW logging. This is a boolean value so only 1 or 0 are permissible values log_size is used to configure the amount of memory the driver uses for log data data is used to read/clear the log data Generally there is a lot of data and dumping that data to syslog will result in a loss of data. This causes problems when decoding the data and the user doesn't know that data is missing until later. Instead of dumping the FW log output to syslog use debugfs. This ensures that all the data the driver has gets retrieved correctly. The FW log data is binary data that the FW team decodes to determine what happened in firmware. The binary blob is sent to Intel for decoding. --- v6: - use seq_printf() for outputting module info when reading from 'module' file - replace code that created argc and argv for handling command line input - removed checks in all the _read() and _write() functions to see if FW logging is supported because the files will not exist if it is not supported - removed warnings on allocation failures on debugfs file creation failures - removed a newline between memory allocation and checking if the memory was allocated - fixed cases where we could just return the value from a function call instead of saving the value in a variable - moved the check for PFO in ice_fwlog_init() to an earlier patch - reworked all of argument scanning in the _write() functions in ice_debugfs.c to remove adding characters past the end of the buffer v5: https://lore.kernel.org/netdev/20231205211251.2122874-1-anthony.l.nguyen@intel.com/ - changed the log level configuration from a single file for all modules to a file per module. - changed 'nr_buffs' to 'log_size' because users understand memory sizes better than a number of buffers - changed 'resolution' to 'nr_messages' to better reflect what it represents - updated documentation to reflect these changes - updated documentation to indicate that FW logging must be disabled to clear the data. also clarified that any value written to the 'data' file will clear the data v4: https://lore.kernel.org/netdev/20231005170110.3221306-1-anthony.l.nguyen@intel.com/ - removed CONFIG_DEBUG_FS wrapper around code because the debugfs calls handle this case already - moved ice_debugfs_exit() call to remove unreachable code issue - minor changes to documentation based on feedback v3: https://lore.kernel.org/netdev/20230815165750.2789609-1-anthony.l.nguyen@intel.com/ - Adjust error path cleanup in ice_module_init() for unreachable code. v2: https://lore.kernel.org/netdev/20230810170109.1963832-1-anthony.l.nguyen@intel.com/ - Rewrote code to use debugfs instead of devlink v1: https://lore.kernel.org/netdev/20230209190702.3638688-1-anthony.l.nguyen@intel.com/ ==================== Signed-off-by:

Tobias Waldekranz says: ==================== net: dsa: mv88e6xxx: Add "eth-mac" and "rmon" counter group support The majority of the changes (2/8) are about refactoring the existing ethtool statistics support to make it possible to read individual counters, rather than the whole set. 4/8 tries to collect all information about a stat in a single place using a mapper macro, which is then used to generate the original list of stats, along with a matching enum. checkpatch is less than amused with this construct, but prior art exists (__BPF_FUNC_MAPPER in include/uapi/linux/bpf.h, for example). To support the histogram counters from the "rmon" group, we have to change mv88e6xxx's configuration of them. Instead of counting rx and tx, we restrict them to rx-only. 6/8 has the details. With that in place, adding the actual counter groups is pretty straight forward (5,7/8). Tie it all together with a selftest (8/8). v3 -> v4: - Return size_t from mv88e6xxx_stats_get_stats - Spelling errors in commit message of 6/8 - Improve selftest: - Report progress per-bucket - Test both ports in the pair - Increase MTU, if required v2 -> v3: - Added 6/8 - Added 8/8 v1 -> v2: - Added 1/6 - Added 3/6 - Changed prototype of stats operation to reflect the fact that the number of read stats are returned, no errors - Moved comma into MV88E6XXX_HW_STAT_MAPPER definition - Avoid the construction of mapping table iteration which relied on struct layouts outside of mv88e6xxx's control ==================== Signed-off-by: -

Chips in this family only have one set of histogram counters, which can be used to count ingressing and/or egressing traffic. mv88e6xxx has, up until this point, kept the hardware default of counting both directions. In the mean time, standard counter group support has been added to ethtool. Via that interface, drivers may report ingress-only and egress-only histograms separately - but not combined. In order for mv88e6xxx to maximize amount of diagnostic information that can be exported via standard interfaces, we opt to limit the histogram counters to ingress traffic only. Which will allow us to export them via the standard "rmon" group in an upcoming commit. The reason for choosing ingress-only over egress-only, is to be compatible with RFC2819 (RMON MIB).

Petr Machata says: ==================== mlxsw: CFF flood mode: NVE underlay configuration Recently, support for CFF flood mode (for Compressed FID Flooding) was added to the mlxsw driver. The most recent patchset has a detailed coverage of what CFF is and what has changed and how: https://lore.kernel.org/netdev/cover.1701183891.git.petrm@nvidia.com/ In CFF flood mode, each FID allocates a handful (in our implementation two or three) consecutive PGT entries. One entry holds the flood vector for unknown-UC traffic, one for MC, one for BC. To determine how to look up flood vectors, the CFF flood mode uses a concept of flood profiles, which are IDs that reference mappings from traffic types to offsets. In the case of CFF flood mode, the offset in question is applied to the PGT address configured at a FID. The same mechanism is used by NVE underlay for flooding. Again the profile ID and the traffic type determine the offset to apply, this time to KVD address used to look up flooding entries. Since mlxsw configures NVE underlay flood the same regardless of traffic type, only one offset was ever needed: the zero, which is the default, and thus no explicit configuration was needed. Now that CFF uses profiles as well, it would be better to configure the profile used by NVE explicitly, to make the configuration visible in the source code. In this patchset, add the register support (in patch #1), add a new traffic type to refer to "any traffic at all" (in patch #2) and finally configure the NVE profile explicitly for FIDs (in patch #3). So far, the implicitly configured flood profile was the ID 0. With this patchset, it changes to 3, leaving the 0 free to allow us to spot missed configuration. ==================== Signed-off-by: -
Petr Machata authored
The NVE flood profile is used for determining of offset applied to KVD address for NVE flood. We currently do not set it, leaving it at the default value of 0. That is not an issue: all the traffic-type-to-offset mappings (as configured by SFFP) default to offset of 0. This is what we need anyway, as mlxsw only allocates a single KVD entry for NVE underlay. The field is only relevant on Spectrum-2 and above. So to be fully consistent, we should split the existing controlled ops to Spectrum-1 and Spectrum>1 variants, with only the latter setting the field. But that seems like a lot of overhead for a single field whose meaning is "everything is the default". So instead pretend that the NVE flood profile does not exist in the controlled flood mode, like we have so far, and only set it when flood mode is CFF. Setting this at all serves dual purpose. First, it is now clear which profile belongs to NVE, because in the CFF mode, we have multiple users. This should prevent bugs in flood profile management. Second, using specifically non-zero value means there will be no valid uses of the profile 0, which we can therefore use as a sentinel. Signed-off-by:

Flood profiles have been used prior to CFF support for NVE underlay. Like is the case with FID flooding, an NVE profile describes at which offset a datum is located given traffic type. mlxsw currently only ever uses one KVD entry for NVE lookup, i.e. regardless of traffic type, the offset is always zero. To be able to describe this, add a traffic type enumerator describing "any traffic type". Signed-off-by:

Arseniy Krasnov says: ==================== send credit update during setting SO_RCVLOWAT DESCRIPTION This patchset fixes old problem with hungup of both rx/tx sides and adds test for it. This happens due to non-default SO_RCVLOWAT value and deferred credit update in virtio/vsock. Link to previous old patchset: https://lore.kernel.org/netdev/39b2e9fd-601b-189d-39a9-914e5574524c@sberdevices.ru/ Here is what happens step by step: TEST INITIAL CONDITIONS 1) Vsock buffer size is 128KB. 2) Maximum packet size is also 64KB as defined in header (yes it is hardcoded, just to remind about that value). 3) SO_RCVLOWAT is default, e.g. 1 byte. STEPS SENDER RECEIVER 1) sends 128KB + 1 byte in a single buffer. 128KB will be sent, but for 1 byte sender will wait for free space at peer. Sender goes to sleep. 2) reads 64KB, credit update not sent 3) sets SO_RCVLOWAT to 64KB + 1 4) poll() -> wait forever, there is only 64KB available to read. So in step 4) receiver also goes to sleep, waiting for enough data or connection shutdown message from the sender. Idea to fix it is that rx kicks tx side to continue transmission (and may be close connection) when rx changes number of bytes to be woken up (e.g. SO_RCVLOWAT) and this value is bigger than number of available bytes to read. I've added small test for this, but not sure as it uses hardcoded value for maximum packet length, this value is defined in kernel header and used to control deferred credit update. And as this is not available to userspace, I can't control test parameters correctly (if one day this define will be changed - test may become useless).

Send credit update message when SO_RCVLOWAT is updated and it is bigger than number of bytes in rx queue. It is needed, because 'poll()' will wait until number of bytes in rx queue will be not smaller than O_RCVLOWAT, so kick sender to send more data. Otherwise mutual hungup for tx/rx is possible: sender waits for free space and receiver is waiting data in 'poll()'. Rename 'set_rcvlowat' callback to 'notify_set_rcvlowat' and set 'sk->sk_rcvlowat' only in one place (i.e. 'vsock_set_rcvlowat'), so the transport doesn't need to do it.
