Andy Roulin says: ==================== net: protodown support for macvlan and vxlan This patch series adds dev_change_proto_down_generic, a generic implementation of ndo_change_proto_down, which sets the netdev carrier state according to the new proto_down value. This handler adds the ability to set protodown on macvlan and vxlan interfaces in a generic way for use by control protocols like VRRPD. Patch (1) introduces the handler in net/code/dev.c. Patch (2) and (3) add support for change_proto_down in macvlan and vxlan drivers, respectively, using the new function. ==================== Signed-off-by: -

Vlad Buslov says: ==================== Add tests for unlocked flower classifier implementation Implement tests for tdc testsuite to verify concurrent rules update with rtnl-unlocked flower classifier implementation. The goal of these tests is to verify general flower classifier correctness by updating filters on same classifier instance in parallel and to verify its atomicity by concurrently updating filters in same handle range. All three filter update operations (add, replace, delete) are tested. Existing script tdc_batch.py is re-used for batch file generation. It is extended with several optional CLI arguments that are needed for concurrency tests. Thin wrapper tdc_multibatch.py is implemented on top of tdc_batch.py to simplify its usage when generating multiple batch files for several test configurations. Parallelism in tests is implemented by running multiple instances of tc in batch mode with xargs tool. Xargs is chosen for its ease of use and because it is available by default on most modern Linux distributions. ==================== Acked-by:

Implement test that runs 5 instances of tc add filter in parallel with 5 instances of tc del filter from same tp instance. Each instance uses its own filter handle and key range. Extend tdc_multibatch.py with additional options required to implement the test: common prefix for all generated batch files, first value of filter handle range, MAC address prefix modifier. These are necessary to allow creating batch files with unique keys and handle ranges with multiple invocation of tdc_multibatch.py helper script. Signed-off-by:

Implement test that verifies concurrent deletion of rules by executing 10 tc instances that delete flower filters in same handle range. In this case only one tc instance succeeds in deleting a filter with particular handle. To mitigate expected failures of all other instances, run tc with 'force' option to continue processing batch file in case of errors and expect xargs to return code '123' that indicates that invocation of command(s) exited with error in range 1-125.

Implement test that verifies parallel rules insertion by adding 1 million flower filters with 10 concurrent tc instances. Put it to standalone 'concurrency' category. Implement tdc_multibatch.py helper script that is used to generate multiple batch files for concurrent tc execution.

Extend tdc_batch.py with several optional CLI arguments that are used for implementation of concurrency tests in following patches in this set: - Add optional argument to specify range of filter handles used in batch file [fitler_handle, filter_handle+number). This is needed for testing filter deletion where it is necessary to know exact handles of configured filters. - Add optional argument to specify filter operation type (possible values are ['add', 'del', 'replace']) instead of hardcoded "add" value. This allows generation of batches for filter addition, deletion and replacement. - Add optional argument to allow user to change mac address prefix that is used for all filters in batch. This is necessary to allow generating multiple batches with unique flower classifier keys. Signed-off-by:

qdisc_pkt_len_init expects transport_header to be set for GSO packets. Patch [1] skips transport_header validation for GSO packets that don't have network_header set at the moment of calling virtio_net_hdr_to_skb, and allows them to pass into the stack. After patch [2] no placeholder value is assigned to transport_header if dissection fails, so this patch adds a check to the place where the value of transport_header is used.

Three conflicts, one of which, for marvell10g.c is non-trivial and requires some follow-up from Heiner or someone else. The issue is that Heiner converted the marvell10g driver over to use the generic c45 code as much as possible. However, in 'net' a bug fix appeared which makes sure that a new local mask (MDIO_AN_10GBT_CTRL_ADV_NBT_MASK) with value 0x01e0 is cleared. Signed-off-by: -

This fixes a regression introduced by commit 0d2e778e "net: phy: replace PHY_HAS_INTERRUPT with a check for config_intr and ack_interrupt". This assumes that a PHY cannot trigger interrupt unless it has .config_intr() or .ack_interrupt() implemented. A later patch makes the code assume both need to be implemented for interrupts to be present. But this PHY (which is inside a DSA) will happily fire interrupts without either callback. Implement dummy callbacks for .config_intr() and .ack_interrupt() in the phy header to fix this. Tested on the RTL8366RB on D-Link DIR-685.

syzbot was able to trigger another soft lockup [1] I first thought it was the O(N^2) issue I mentioned in my prior fix (f657d22ee1f "net/x25: do not hold the cpu too long in x25_new_lci()"), but I eventually found that x25_bind() was not checking SOCK_ZAPPED state under socket lock protection. This means that multiple threads can end up calling x25_insert_socket() for the same socket, and corrupt x25_list [1] watchdog: BUG: soft lockup - CPU#0 stuck for 123s!

This reverts commit 5a2de63f ("bridge: do not add port to router list when receives query with source 0.0.0.0") and commit 0fe5119e ("net: bridge: remove ipv6 zero address check in mcast queries") The reason is RFC 4541 is not a standard but suggestive. Currently we will elect 0.0.0.0 as Querier if there is no ip address configured on bridge. If we do not add the port which recives query with source 0.0.0.0 to router list, the IGMP reports will not be about to forward to Querier, IGMP data will also not be able to forward to dest. As Nikolay suggested, revert this change first and add a boolopt api to disable none-zero election in future if needed. Reported-by:

Just like commit e2ba732a ("selftests: fib_tests: sleep after changing carrier"), wait one second to allow linkwatch to propagate the carrier change to the stack. There are two sets of carrier tests. The first slept after the carrier was set to off, and when the second set ran, it was likely that the linkwatch would be able to run again without much delay, reducing the likelihood of a race. However, if you run 'fib_tests.sh -t carrier' on a loop, you will quickly notice the failures. Sleeping on the second set of tests make the failures go away.

Because 1000BaseT isn't covered by Clause 45, the 1000BaseT flags in phydev->lp_advertising may have been set based on vendor registers already. genphy_c45_read_lpa() would clear these flags as of today. Therefore switch to mii_lpa_mod_linkmode_lpa_t. Signed-off-by:

Ido Schimmel says: ==================== mlxsw: Add support for new port types and speeds for Spectrum-2 Shalom says: This patchset adds support for new port types and speeds for Spectrum-2. Patch #1 + #2 removes an unsupported PTYS field and a duplicate link mode entry. Patch #3 queries port's connector type from firmware instead of deriving it from port admin state. Patch #4 renames functions which relate to port type-speed to be Spectrum-1 specific. Patch #5 defines port type-speed operations and applies it for Spectrum-1. Patch #6 + #7 are small renaming and cosmetic changes. Patch #8 adds new port type-speed fields for PTYS register. These new fields extend the existing ones in order to support more types and speeds. Patch #9 adds Spectrum-2 support for port type-speed operations. Patch #10 adds Spectrum-2 new port types and speeds. For Spectrum-2, the user must configure all the types per speed if he / she wants a specific speed to be advertised. For example, if the user wants to advertise 100Gbps 4-lanes speed, the following ethtool bits should be advertised: Supported ethtool bits for 100Gbps 4-lanes: 0x1000000000 100000baseKR4 Full 0x2000000000 100000baseSR4 Full 0x4000000000 100000baseCR4 Full 0x8000000000 100000baseLR4_ER4 Full Command for advertising 100Gbps 4-lanes: ethtool -s enp3s0np1 advertise 0xF000000000 ==================== Signed-off-by: -

Add Spectrum-2 ASIC port type-speed operations. Since multiple ethtool link modes are represented using a single bit in the ASIC, the driver forces the user to configure all types per a specific speed. For example, if the user wants to advertise 100Gbps 4-lanes speed, he should advertise all the types of 100Gbps 4-lanes speed that are supported by the ASIC as shown below: Supported ethtool bits for 100Gbps 4-lanes: 0x1000000000 100000baseKR4 Full 0x2000000000 100000baseSR4 Full 0x4000000000 100000baseCR4 Full 0x8000000000 100000baseLR4_ER4 Full Command for advertising 100Gbps 4-lanes: ethtool -s enp3s0np1 advertise 0xF000000000 Signed-off-by:
