This patch optimizes hclge_handle_hw_ras_error() to make the code logic clearer. 1. If there was no NIC or Roce RAS when we read HCLGE_RAS_PF_OTHER_INT_STS_REG, we return directly. 2. Because NIC and Roce RAS may occurs at the same time, so we should check value of revision at first before we handle Roce RAS instead of only checking it in branch of no NIC RAS is detected. 3. Check HCLGE_STATE_RST_HANDLING each time before we want to return PCI_ERS_RESULT_NEED_RESET. 4. Remove checking of HCLGE_RAS_REG_NFE_MASK and HCLGE_RAS_REG_ROCEE_ERR_MASK because if hw_err_reset_req is not zero, it proves that we have set it in handling of NIC or Roce RAS. Signed-off-by:

When HW is resetting, firmware is unable to handle commands from driver. So if remove VLAN device from stack at this time, it will fail to remove the VLAN ID from HW VLAN filter, then the VLAN filter status is unsynced with stack.

In commit a4dc70d4 ("tipc: extend link reset criteria for stale packet retransmission") we made link retransmission failure events dependent on the link tolerance, and not only of the number of failed retransmission attempts, as we did earlier. This works well. However, keeping the original, additional criteria of 99 failed retransmissions is now redundant, and may in some cases lead to failure detection times in the order of minutes instead of the expected 1.5 sec link tolerance value. We now remove this criteria altogether. Acked-by:

This patch restores the original behaviour for tdc prior to the introduction of the plugin system, where the network namespace functionality was split from the main script. It introduces the concept of required plugins for testcases, and will automatically load any plugin that isn't already enabled when said plugin is required by even one testcase. Additionally, the -n option for the nsPlugin is deprecated so the default action is to make use of the namespaces. Instead, we introduce -N to not use them, but still create the veth pair. buildebpfPlugin's -B option is also deprecated. If a test cases requires the features of a specific plugin in order to pass, it should instead include a new key/value pair describing plugin interactions: "plugins": { "requires": "buildebpfPlugin" }, A test case can have more than one required plugin: a list can be inserted as the value for 'requires'.

The PHY selection bit also exists on SoCs without an internal PHY; if it's set to 1 (internal PHY, default value) then the MAC will not make use of any PHY on such SoCs. This problem appears when adapting for H6, which has no real internal PHY (the "internal PHY" on H6 is not on-die, but on a co-packaged AC200 chip, connected via RMII interface at GPIO bank A). Force the PHY selection bit to 0 when the SOC doesn't have an internal PHY, to address the problem of a wrong default value. Signed-off-by:

Stefano Brivio says: ==================== Fix listing (IPv4, IPv6) and flushing (IPv6) of cached route exceptions For IPv6 cached routes, the commands 'ip -6 route list cache' and 'ip -6 route flush cache' don't work at all after route exceptions have been moved to a separate hash table in commit 2b760fcf ("ipv6: hook up exception table to store dst cache"). For IPv4 cached routes, the command 'ip route list cache' has also stopped working in kernel 3.5 after commit 4895c771 ("ipv4: Add FIB nexthop exceptions.") introduced storage for route exceptions as a separate entity. Fix this by allowing userspace to clearly request cached routes with the RTM_F_CLONED flag used as a filter (in conjuction with strict checking) and by retrieving and dumping cached routes if requested. If strict checking is not requested (iproute2 < 5.0.0), we don't have a way to consistently filter results on other selectors (e.g. on tables), so skip filtering entirely and dump both regular routes and exceptions. For IPv4, cache flushing uses a completely different mechanism, so it wasn't affected. Listing of exception routes (modified routes pre-3.5) was tested against these versions of kernel and iproute2: iproute2 kernel 4.14.0 4.15.0 4.19.0 5.0.0 5.1.0 3.5-rc4 + + + + + 4.4 4.9 4.14 4.15 4.19 5.0 5.1 fixed + + + + + For IPv6, a separate iproute2 patch is required.

Merge selftests into this series (as they were addressed for net-next). A number of minor changes detailed in logs of single patches. v5: Skip filtering altogether if no strict checking is requested: selecting routes or exceptions only would be inconsistent with the fact we can't filter on tables. Drop 1/8 (non-strict dump filter function no longer needed), replace 2/8 (don't use NLM_F_MATCH, decide to skip routes or exceptions in filter function), drop 6/8 (2/8 is enough for IPv6 too). Introduce dump_routes and dump_exceptions flags in filter, adapt other patches to that. v4: Fix the listing issue also for IPv4, making the behaviour consistent with IPv6. Honour NLM_F_MATCH as per RFC 3549 and allow usage of RTM_F_CLONED filter. Split patches into smaller logical changes. v3: Drop check on RTM_F_CLONED and rework logic of return values of rt6_dump_route() v2: Add count of routes handled in partial dumps, and skip them, in patch 1/2. ==================== Signed-off-by:

Instead of just listing and flushing two cached exceptions, create a relatively big number of them, and count how many are listed. Single netlink dump messages contain approximately 25 entries each, and this way we can make sure the partial dump tracking mechanism is working properly. While at it, also ensure that no cached routes can be listed after flush, and remove 'sleep 1' calls, they are not actually needed. v7: No changes v6: - Merge this patch into series including fix, as it's also targeted for net-next.

When we perform an inexact match on FIB nodes via fib6_locate_1(), longer prefixes will be preferred to shorter ones. However, it might happen that a node, with higher fn_bit value than some other, has no valid routing information. In this case, we'll pick that node, but it will be discarded by the check on RTN_RTINFO in fib6_locate(), and we might miss nodes with valid routing information but with lower fn_bit value. This is apparent when a routing exception is created for a default route: # ip -6 route list fc00:1::/64 dev veth_A-R1 proto kernel metric 256 pref medium fc00:2::/64 dev veth_A-R2 proto kernel metric 256 pref medium fc00:4::1 via fc00:2::2 dev veth_A-R2 metric 1024 pref medium fe80::/64 dev veth_A-R1 proto kernel metric 256 pref medium fe80::/64 dev veth_A-R2 proto kernel metric 256 pref medium default via fc00:1::2 dev veth_A-R1 metric 1024 pref medium # ip -6 route list cache fc00:4::1 via fc00:2::2 dev veth_A-R2 metric 1024 expires 593sec mtu 1500 pref medium fc00:3::1 via fc00:1::2 dev veth_A-R1 metric 1024 expires 593sec mtu 1500 pref medium # ip -6 route flush cache # node for default route is discarded Failed to send flush request: No such process # ip -6 route list cache fc00:3::1 via fc00:1::2 dev veth_A-R1 metric 1024 expires 586sec mtu 1500 pref medium Check right away if the node has a RTN_RTINFO flag, before replacing the 'prev' pointer, that indicates the longest matching prefix found so far.

Since commit 2b760fcf ("ipv6: hook up exception table to store dst cache"), route exceptions reside in a separate hash table, and won't be found by walking the FIB, so they won't be dumped to userspace on a RTM_GETROUTE message. This causes 'ip -6 route list cache' and 'ip -6 route flush cache' to have no function anymore: # ip -6 route get fc00:3::1 fc00:3::1 via fc00:1::2 dev veth_A-R1 src fc00:1::1 metric 1024 expires 539sec mtu 1400 pref medium # ip -6 route get fc00:4::1 fc00:4::1 via fc00:2::2 dev veth_A-R2 src fc00:2::1 metric 1024 expires 536sec mtu 1500 pref medium # ip -6 route list cache # ip -6 route flush cache # ip -6 route get fc00:3::1 fc00:3::1 via fc00:1::2 dev veth_A-R1 src fc00:1::1 metric 1024 expires 520sec mtu 1400 pref medium # ip -6 route get fc00:4::1 fc00:4::1 via fc00:2::2 dev veth_A-R2 src fc00:2::1 metric 1024 expires 519sec mtu 1500 pref medium because iproute2 lists cached routes using RTM_GETROUTE, and flushes them by listing all the routes, and deleting them with RTM_DELROUTE one by one. If cached routes are requested using the RTM_F_CLONED flag together with strict checking, or if no strict checking is requested (and hence we can't consistently apply filters), look up exceptions in the hash table associated with the current fib6_info in rt6_dump_route(), and, if present and not expired, add them to the dump. We might be unable to dump all the entries for a given node in a single message, so keep track of how many entries were handled for the current node in fib6_walker, and skip that amount in case we start from the same partially dumped node. When a partial dump restarts, as the starting node might change when 'sernum' changes, we have no guarantee that we need to skip the same amount of in-node entries. Therefore, we need two counters, and we need to zero the in-node counter if the node from which the dump is resumed differs. Note that, with the current version of iproute2, this only fixes the 'ip -6 route list cache': on a flush command, iproute2 doesn't pass RTM_F_CLONED and, due to this inconsistency, 'ip -6 route flush cache' is still unable to fetch the routes to be flushed. This will be addressed in a patch for iproute2. To flush cached routes, a procfs entry could be introduced instead: that's how it works for IPv4. We already have a rt6_flush_exception() function ready to be wired to it. However, this would not solve the issue for listing. Versions of iproute2 and kernel tested: iproute2 kernel 4.14.0 4.15.0 4.19.0 5.0.0 5.1.0 5.1.0, patched 3.18 list + + + + + + flush + + + + + + 4.4 list + + + + + + flush + + + + + + 4.9 list + + + + + + flush + + + + + + 4.14 list + + + + + + flush + + + + + + 4.15 list flush 4.19 list flush 5.0 list flush 5.1 list flush with list + + + + + + fix flush + + + + v7: - Explain usage of "skip" counters in commit message (suggested by David Ahern) v6: - Rebase onto net-next, use recently introduced nexthop walker - Make rt6_nh_dump_exceptions() a separate function (suggested by David Ahern) v5: - Use dump_routes and dump_exceptions from filter, ignore NLM_F_MATCH, update test results (flushing works with iproute2 < 5.0.0 now) v4: - Split NLM_F_MATCH and strict check handling in separate patches - Filter routes using RTM_F_CLONED: if it's not set, only return non-cached routes, and if it's set, only return cached routes: change requested by David Ahern and Martin Lau. This implies that iproute2 needs a separate patch to be able to flush IPv6 cached routes. This is not ideal because we can't fix the breakage caused by 2b760fcf entirely in kernel. However, two years have passed since then, and this makes it more tolerable v3: - More descriptive comment about expired exceptions in rt6_dump_route() - Swap return values of rt6_dump_route() (suggested by Martin Lau) - Don't zero skip_in_node in case we don't dump anything in a given pass (also suggested by Martin Lau) - Remove check on RTM_F_CLONED altogether: in the current UAPI semantic, it's just a flag to indicate the route was cloned, not to filter on routes v2: Add tracking of number of entries to be skipped in current node after a partial dump. As we restart from the same node, if not all the exceptions for a given node fit in a single message, the dump will not terminate, as suggested by Martin Lau. This is a concrete possibility, setting up a big number of exceptions for the same route actually causes the issue, suggested by David Ahern. Reported-by:

In the next patch, we are going to add optional dump of exceptions to rt6_dump_route(). Change the return code of rt6_dump_route() to accomodate partial node dumps: we might dump multiple routes per node, and might be able to dump only a given number of them, so fib6_dump_node() will need to know how many routes have been dumped on partial dump, to restart the dump from the point where it was interrupted. Note that fib6_dump_node() is the only caller and already handles all non-negative return codes as success: those become -1 to signal that we're done with the node. If we fail, return 0, as we were unable to dump the single route in the node, but we're not done with it. Signed-off-by:

Stefano Brivio authored
Since commit 4895c771 ("ipv4: Add FIB nexthop exceptions."), cached exception routes are stored as a separate entity, so they are not dumped on a FIB dump, even if the RTM_F_CLONED flag is passed. This implies that the command 'ip route list cache' doesn't return any result anymore. If the RTM_F_CLONED is passed, and strict checking requested, retrieve nexthop exception routes and dump them. If no strict checking is requested, filtering can't be performed consistently: dump everything in that case. With this, we need to add an argument to the netlink callback in order to track how many entries were already dumped for the last leaf included in a partial netlink dump. A single additional argument is sufficient, even if we traverse logically nested structures (nexthop objects, hash table buckets, bucket chains): it doesn't matter if we stop in the middle of any of those, because they are always traversed the same way. As an example, s_i values in [], s_fa values in (): node (fa) #1 [1] nexthop #1 bucket #1 -> #0 in chain (1) bucket #2 -> #0 in chain (2) -> #1 in chain (3) -> #2 in chain (4) bucket #3 -> #0 in chain (5) -> #1 in chain (6) nexthop #2 bucket #1 -> #0 in chain (7) -> #1 in chain (8) bucket #2 -> #0 in chain (9) -- node (fa) #2 [2] nexthop #1 bucket #1 -> #0 in chain (1) -> #1 in chain (2) bucket #2 -> #0 in chain (3) it doesn't matter if we stop at (3), (4), (7) for "node #1", or at (2) for "node #2": walking flattens all that. It would even be possible to drop the distinction between the in-tree (s_i) and in-node (s_fa) counter, but a further improvement might advise against this. This is only as accurate as the existing tracking mechanism for leaves: if a partial dump is restarted after exceptions are removed or expired, we might skip some non-dumped entries. To improve this, we could attach a 'sernum' attribute (similar to the one used for IPv6) to nexthop entities, and bump this counter whenever exceptions change: having a distinction between the two counters would make this more convenient. Listing of exception routes (modified routes pre-3.5) was tested against these versions of kernel and iproute2: iproute2 kernel 4.14.0 4.15.0 4.19.0 5.0.0 5.1.0 3.5-rc4 + + + + + 4.4 4.9 4.14 4.15 4.19 5.0 5.1 fixed + + + + + v7: - Move loop over nexthop objects to route.c, and pass struct fib_info and table ID to it, not a struct fib_alias (suggested by David Ahern) - While at it, note that the NULL check on fa->fa_info is redundant, and the check on RTNH_F_DEAD is also not consistent with what's done with regular route listing: just keep it for nhc_flags - Rename entry point function for dumping exceptions to fib_dump_info_fnhe(), and rearrange arguments for consistency with fib_dump_info() - Rename fnhe_dump_buckets() to fnhe_dump_bucket() and make it handle one bucket at a time - Expand commit message to describe why we can have a single "skip" counter for all exceptions stored in bucket chains in nexthop objects (suggested by David Ahern) v6: - Rebased onto net-next - Loop over nexthop paths too.

The following patches add back the ability to dump IPv4 and IPv6 exception routes, and we need to allow selection of regular routes or exceptions. Use RTM_F_CLONED as filter to decide whether to dump routes or exceptions: iproute2 passes it in dump requests (except for IPv6 cache flush requests, this will be fixed in iproute2) and this used to work as long as exceptions were stored directly in the FIB, for both IPv4 and IPv6. Caveat: if strict checking is not requested (that is, if the dump request doesn't go through ip_valid_fib_dump_req()), we can't filter on protocol, tables or route types. In this case, filtering on RTM_F_CLONED would be inconsistent: we would fix 'ip route list cache' by returning exception routes and at the same time introduce another bug in case another selector is present, e.g. on 'ip route list cache table main' we would return all exception routes, without filtering on tables. Keep this consistent by applying no filters at all, and dumping both routes and exceptions, if strict checking is not requested. iproute2 currently filters results anyway, and no unwanted results will be presented to the user. The kernel will just dump more data than needed. v7: No changes v6: Rebase onto net-next, no changes v5: New patch: add dump_routes and dump_exceptions flags in filter and simply clear the unwanted one if strict checking is enabled, don't ignore NLM_F_MATCH and don't set filter_set if NLM_F_MATCH is set. Skip filtering altogether if no strict checking is requested: selecting routes or exceptions only would be inconsistent with the fact we can't filter on tables. Signed-off-by: -

Suppose we have two interfaces eth0 and eth1 in two hosts, follow the same steps in the two hosts: # sysctl -w net.ipv4.conf.eth1.route_localnet=1 # sysctl -w net.ipv4.conf.eth1.arp_announce=2 # ip route del 127.0.0.0/8 dev lo table local and then set ip to eth1 in host1 like: # ifconfig eth1 127.25.3.4/24 set ip to eth2 in host2 and ping host1: # ifconfig eth1 127.25.3.14/24 # ping -I eth1 127.25.3.4 Well, host2 cannot connect to host1. When set a ip address with head 127, the scope of the address defaults to RT_SCOPE_HOST. In this situation, host2 will use arp_solicit() to send a arp request for the mac address of host1 with ip address 127.25.3.14. When arp_announce=2, inet_select_addr() cannot select a correct saddr with condition ifa->ifa_scope > scope, because ifa_scope is RT_SCOPE_HOST and scope is RT_SCOPE_LINK. Then, inet_select_addr() will go to no_in_dev to lookup all interfaces to find a primary ip and finally get the primary ip of eth0. Here I add a localnet_scope defaults to RT_SCOPE_HOST, and when route_localnet is enabled, this value changes to RT_SCOPE_LINK to make inet_select_addr() find a correct primary ip as saddr of arp request.

tipc_nl_compat_bearer_set() is only called by tipc_nl_compat_link_set() which already does the check for msg->req check, so remove it from tipc_nl_compat_bearer_set(), and do the same in tipc_nl_compat_media_set(). Signed-off-by:

Ido Schimmel says: ==================== mlxsw: Thermal and hwmon extensions This patchset from Vadim includes various enhancements to thermal and hwmon code in mlxsw. Patch #1 adds a thermal zone for each inter-connect device (gearbox). These devices are present in SN3800 systems and code to expose their temperature via hwmon was added in commit 2e265a8b ("mlxsw: core: Extend hwmon interface with inter-connect temperature attributes"). Currently, there are multiple thermal zones in mlxsw and only a few cooling devices. Patch #2 detects the hottest thermal zone and the cooling devices are switched to follow its trends. RFC was sent last month [1]. Patch #3 allows to read and report negative temperature of the sensors mlxsw exposes via hwmon and thermal subsystems. v2 (Andrew Lunn): * In patch #3, replace '%u' with '%d' in mlxsw_hwmon_module_temp_show() [1] https://patchwork.ozlabs.org/patch/1107161/ ==================== Signed-off-by:
