2020-12-02net: ipa: use Qtime for IPA v4.5 aggregation time limitAlex Elder1-4/+28
Change aggr_time_limit_encoded() to properly calculate the aggregation time limit to use for IPA v4.5. Older IPA versions program the AGGR_GRANULARITY field of the of the COUNTER_CFG register to set the granularity of the aggregation timer, which we configure to be 500 microseconds. Instead, IPA v4.5 selects between two possible granularity values derived from the 19.2 MHz Qtime clock. These granularities are 100 microseconds or 1 millisecond per tick. We use the smaller granularity if possible, unless the desired period is too large to be specified that way.

2020-12-02net: ipa: set up IPA v4.5 Qtime configurationAlex Elder2-4/+93
IPA v4.5 introduces a new unified timer architecture driven on the 19.2 MHz SoC crystal oscillator (XO). It is independent of the IPA core clock and avoids some duplication. Lower-resolution time stamps are derived from this by using only the high-order bits of the 19.2 MHz Qtime clock. And timers are derived from this based on "pulse generators" configured to fire at a fixed rate based on the Qtime clock. This patch introduces ipa_qtime_config(), which configures the Qtime mechanism for use. It also adds to the IPA register definitions related to timers and time stamping.

2020-12-02net: ipa: update IPA aggregation registers for IPA v4.5Alex Elder2-39/+101
IPA v4.5 significantly changes the format of the configuration register used for endpoint aggregation. The AGGR_BYTE_LIMIT field is now larger, and the positions of other fields are shifted. This complicates the way we have to access this register because functions like u32_encode_bits() require their field mask argument to be constant. A further complication is that we want to know the maximum value representable by at least one of these fields, and that too requires a constant field mask. This patch adds support for IPA v4.5 endpoint aggregation registers in a way that continues to support "legacy" IPA hardware. It does so in a way that keeps field masks constant. First, for each variable field mask, we define an inline function whose return value is either the legacy value or the IPA v4.5 value. Second, we define functions for these fields that encode a value to use in each field based on the IPA version (this approach is already used elsewhere). The field mask provided is supplied by the function mentioned above. Finally, for the aggregation byte limit fields where we want to know the maximum representable value, we define a function that returns that maximum, computed from the appropriate field mask. We can no longer verify at build time that our buffer size is in the range that can be represented by the aggregation byte limit field. So remove the test done by a BUILD_BUG_ON() call in ipa_endpoint_validate_build(), and implement a comparable check at the top of ipa_endpoint_data_valid(). Doing that makes ipa_endpoint_validate_build() contain a single line BUILD_BUG_ON() call, so just remove that function and move the remaining line into ipa_endpoint_data_valid(). One final note: the aggregation time limit value for IPA v4.5 needs to be computed differently. That is handled in an upcoming patch.

Karsten Graul says: ==================== net/smc: Add support for generic netlink API Up to version 4 this patch series was using the sock_diag netlink infrastructure. This version is using the generic netlink API. Generic netlink API offers a better type safety between kernel and userspace communication. Using the generic netlink API the smc module can now provide information about SMC linkgroups, links and devices (both for SMC-R and SMC-D). v2: Add missing include to uapi header smc_diag.h. v3: Apply code style recommendations from review comments. Instead of using EXPORTs to allow the smc_diag module to access data of the smc module, introduce struct smc_diag_ops and let smc_diag access the required data using function pointers. v4: Address checkpatch.pl warnings. Do not use static inline for functions. v5: Use generic netlink API instead of the sock_diag netlink infrastructure. v6: Integrate more review comments from Jakub. v7: Use nla_nest_start() with the new family. Use .maxattr=1 in the genl family and define one entry for attribute 1 in the policy to reject this attritbute for all commands. All other possible attributes are rejected because NL_VALIDATE_STRICT is set for the policy implicitely, which includes NL_VALIDATE_MAXTYPE. Setting policy[0].strict_start_type=1 does not work here because there is no valid attribute defined for this family, only plain commands. For any type > maxtype (which is .maxattr) validate_nla() would return 0 to userspace instead of -EINVAL. What helps here is __nla_validate_parse() which checks for type > maxtype and returns -EINVAL when NL_VALIDATE_MAXTYPE is set. This requires the one entry for type == .maxattr with .type = NLA_REJECT in the nla_policy. When a future command wants to allow attributes then it can easily specify a dedicated .policy for this new command in the genl_ops array. This dedicated policy overlays the global policy specified in the genl_family structure. ==================== Link: https://lore.kernel.org/r/20201201192049.53517-1-kgraul@linux.ibm.com Signed-off-by: Jakub Kicinski <kuba@kernel.org>

Add many struct field and function parameter descriptions. Then add a TIPC chapter to the networking documentation book. All patches have been rebased to current net-next. Note: some of the struct members and function parameters are marked with "FIXME". They could use some additional descriptions if someone could help add to them.

2020-12-02tipc: fix incompatible mtu of transmissionHoang Le1-0/+2
In commit 682cd3cf946b6 ("tipc: confgiure and apply UDP bearer MTU on running links"), we introduced a function to change UDP bearer MTU and applied this new value across existing per-link. However, we did not apply this new MTU value at node level. This lead to packet dropped at link level if its size is greater than new MTU value. To fix this issue, we also apply this new MTU value for node level.

2020-12-02Merge branch 'mlxsw-add-support-for-802-1ad-bridging'Jakub Kicinski8-21/+657
Ido Schimmel says: ==================== mlxsw: Add support for 802.1ad bridging 802.1ad, also known as QinQ, is an extension to the 802.1q standard, which is concerned with passing possibly 802.1q-tagged packets through another VLAN-like tunnel. The format of 802.1ad tag is the same as 802.1q, except it uses the EtherType of 0x88a8, unlike 802.1q's 0x8100. Currently, mlxsw supports bridging with VLAN-unaware (802.1d) bridges and with VLAN-aware bridges whose VLAN protocol is 802.1q. This set adds support for VLAN-aware bridges whose VLAN protocol is 802.1ad. From mlxsw perspective, 802.1ad support entails two main changes: 1. Ports member in an 802.1ad bridge need to be configured to classify 802.1ad packets as tagged and all other packets as untagged 2. When pushing a VLAN at ingress (PVID), its EtherType needs to be 0x88a8 instead of 802.1q's 0x8100 The rest stays the same as with 802.1q bridges. A follow-up patch set will add support for QinQ with VXLAN, also known as QinVNI. Currently, linking of a VXLAN netdev to an 802.1ad bridge is vetoed and an error is returned to user space. Patch set overview: Patches #1-#2 add the registers required to configure the two changes described above. Patch #3 changes the device to only treat 802.1q packets as tagged by default, as opposed to both 802.1q and 802.1ad packets. This is more inline with the behavior supported by the driver. Patch #4 adds the ability to configure the EtherType when pushing a PVID at ingress. Patch #5 performs small refactoring to allow for code re-use in the next patch. Patch #6 adds support for 802.1ad bridging and allows mlxsw ports and their uppers to join such a bridge. Patch #7 changes the bridge driver to notify about changes to its VLAN protocol, so that these could be vetoed by mlxsw in the next patch. Patches #8-#9 teach mlxsw to veto unsupported 802.1ad configurations and add a corresponding selftest to make sure such configurations are indeed vetoed. ==================== Link: https://lore.kernel.org/r/20201129125407.1391557-1-idosch@idosch.org Signed-off-by: Jakub Kicinski <kuba@kernel.org>
