When on a MANA VM hibernation is triggered, as part of hibernate_snapshot(), mana_gd_suspend() and mana_gd_resume() are called. If during this mana_gd_resume(), a failure occurs with HWC creation, mana_port_debugfs pointer does not get reinitialized and ends up pointing to older, cleaned-up dentry. Further in the hibernation path, as part of power_down(), mana_gd_shutdown() is triggered. This call, unaware of the failures in resume, tries to cleanup the already cleaned up mana_port_debugfs value and hits the following bug: [ 191.359296] mana 7870:00:00.0: Shutdown was called [ 191.359918] BUG: kernel NULL pointer dereference, address: 0000000000000098 [ 191.360584] #PF: supervisor write access in kernel mode [ 191.361125] #PF: error_code(0x0002) - not-present page [ 191.361727] PGD 1080ea067 P4D 0 [ 191.362172] Oops: Oops: 0002 [#1] SMP NOPTI [ 191.362606] CPU: 11 UID: 0 PID: 1674 Comm: bash Not tainted 6.14.0-rc5+ #2 [ 191.363292] Hardware name: Microsoft Corporation Virtual Machine/Virtual Machine, BIOS Hyper-V UEFI Release v4.1 11/21/2024 [ 191.364124] RIP: 0010:down_write+0x19/0x50 [ 191.364537] Code: 90 90 90 90 90 90 90 90 90 90 90 90 90 90 90 90 90 0f 1f 44 00 00 55 48 89 e5 53 48 89 fb e8 de cd ff ff 31 c0 ba 01 00 00 00 <f0> 48 0f b1 13 75 16 65 48 8b 05 88 24 4c 6a 48 89 43 08 48 8b 5d [ 191.365867] RSP: 0000:ff45fbe0c1c037b8 EFLAGS: 00010246 [ 191.366350] RAX: 0000000000000000 RBX: 0000000000000098 RCX: ffffff8100000000 [ 191.366951] RDX: 0000000000000001 RSI: 0000000000000064 RDI: 0000000000000098 [ 191.367600] RBP: ff45fbe0c1c037c0 R08: 0000000000000000 R09: 0000000000000001 [ 191.368225] R10: ff45fbe0d2b01000 R11: 0000000000000008 R12: 0000000000000000 [ 191.368874] R13: 000000000000000b R14: ff43dc27509d67c0 R15: 0000000000000020 [ 191.369549] FS: 00007dbc5001e740(0000) GS:ff43dc663f380000(0000) knlGS:0000000000000000 [ 191.370213] CS: 0010 DS: 0000 ES: 0000 CR0: 0000000080050033 [ 191.370830] CR2: 0000000000000098 CR3: 0000000168e8e002 CR4: 0000000000b73ef0 [ 191.371557] DR0: 0000000000000000 DR1: 0000000000000000 DR2: 0000000000000000 [ 191.372192] DR3: 0000000000000000 DR6: 00000000fffe07f0 DR7: 0000000000000400 [ 191.372906] Call Trace: [ 191.373262] <TASK> [ 191.373621] ? show_regs+0x64/0x70 [ 191.374040] ? __die+0x24/0x70 [ 191.374468] ? page_fault_oops+0x290/0x5b0 [ 191.374875] ? do_user_addr_fault+0x448/0x800 [ 191.375357] ? exc_page_fault+0x7a/0x160 [ 191.375971] ? asm_exc_page_fault+0x27/0x30 [ 191.376416] ? down_write+0x19/0x50 [ 191.376832] ? down_write+0x12/0x50 [ 191.377232] simple_recursive_removal+0x4a/0x2a0 [ 191.377679] ? __pfx_remove_one+0x10/0x10 [ 191.378088] debugfs_remove+0x44/0x70 [ 191.378530] mana_detach+0x17c/0x4f0 [ 191.378950] ? __flush_work+0x1e2/0x3b0 [ 191.379362] ? __cond_resched+0x1a/0x50 [ 191.379787] mana_remove+0xf2/0x1a0 [ 191.380193] mana_gd_shutdown+0x3b/0x70 [ 191.380642] pci_device_shutdown+0x3a/0x80 [ 191.381063] device_shutdown+0x13e/0x230 [ 191.381480] kernel_power_off+0x35/0x80 [ 191.381890] hibernate+0x3c6/0x470 [ 191.382312] state_store+0xcb/0xd0 [ 191.382734] kobj_attr_store+0x12/0x30 [ 191.383211] sysfs_kf_write+0x3e/0x50 [ 191.383640] kernfs_fop_write_iter+0x140/0x1d0 [ 191.384106] vfs_write+0x271/0x440 [ 191.384521] ksys_write+0x72/0xf0 [ 191.384924] __x64_sys_write+0x19/0x20 [ 191.385313] x64_sys_call+0x2b0/0x20b0 [ 191.385736] do_syscall_64+0x79/0x150 [ 191.386146] ? __mod_memcg_lruvec_state+0xe7/0x240 [ 191.386676] ? __lruvec_stat_mod_folio+0x79/0xb0 [ 191.387124] ? __pfx_lru_add+0x10/0x10 [ 191.387515] ? queued_spin_unlock+0x9/0x10 [ 191.387937] ? do_anonymous_page+0x33c/0xa00 [ 191.388374] ? __handle_mm_fault+0xcf3/0x1210 [ 191.388805] ? __count_memcg_events+0xbe/0x180 [ 191.389235] ? handle_mm_fault+0xae/0x300 [ 191.389588] ? do_user_addr_fault+0x559/0x800 [ 191.390027] ? irqentry_exit_to_user_mode+0x43/0x230 [ 191.390525] ? irqentry_exit+0x1d/0x30 [ 191.390879] ? exc_page_fault+0x86/0x160 [ 191.391235] entry_SYSCALL_64_after_hwframe+0x76/0x7e [ 191.391745] RIP: 0033:0x7dbc4ff1c574 [ 191.392111] Code: c7 00 16 00 00 00 b8 ff ff ff ff c3 66 2e 0f 1f 84 00 00 00 00 00 f3 0f 1e fa 80 3d d5 ea 0e 00 00 74 13 b8 01 00 00 00 0f 05 <48> 3d 00 f0 ff ff 77 54 c3 0f 1f 00 55 48 89 e5 48 83 ec 20 48 89 [ 191.393412] RSP: 002b:00007ffd95a23ab8 EFLAGS: 00000202 ORIG_RAX: 0000000000000001 [ 191.393990] RAX: ffffffffffffffda RBX: 0000000000000005 RCX: 00007dbc4ff1c574 [ 191.394594] RDX: 0000000000000005 RSI: 00005a6eeadb0ce0 RDI: 0000000000000001 [ 191.395215] RBP: 00007ffd95a23ae0 R08: 00007dbc50003b20 R09: 0000000000000000 [ 191.395805] R10: 0000000000000001 R11: 0000000000000202 R12: 0000000000000005 [ 191.396404] R13: 00005a6eeadb0ce0 R14: 00007dbc500045c0 R15: 00007dbc50001ee0 [ 191.396987] </TASK> To fix this, we explicitly set such mana debugfs variables to NULL after debugfs_remove() is called.

mlx5_eswitch_get_vepa returns -EPERM if the device lacks eswitch_manager capability, blocking mlx5e_bridge_getlink from retrieving VEPA mode. Since mlx5e_bridge_getlink implements ndo_bridge_getlink, returning -EPERM causes bridge link show to fail instead of skipping devices without this capability. To avoid this, return -EOPNOTSUPP from mlx5e_bridge_getlink when mlx5_eswitch_get_vepa fails, ensuring the command continues processing other devices while ignoring those without the necessary capability.

When removing LAG device from bridge, NETDEV_CHANGEUPPER event is triggered. Driver finds the lower devices (PFs) to flush all the offloaded entries. And mlx5_lag_is_shared_fdb is checked, it returns false if one of PF is unloaded. In such case, mlx5_esw_bridge_lag_rep_get() and its caller return NULL, instead of the alive PF, and the flush is skipped. Besides, the bridge fdb entry's lastuse is updated in mlx5 bridge event handler. But this SWITCHDEV_FDB_ADD_TO_BRIDGE event can be ignored in this case because the upper interface for bond is deleted, and the entry will never be aged because lastuse is never updated. To make things worse, as the entry is alive, mlx5 bridge workqueue keeps sending that event, which is then handled by kernel bridge notifier.

Currently, ovs_ct_set_labels() is only called for confirmed conntrack entries (ct) within ovs_ct_commit(). However, if the conntrack entry does not have the labels_ext extension, attempting to allocate it in ovs_ct_get_conn_labels() for a confirmed entry triggers a warning in nf_ct_ext_add(): WARN_ON(nf_ct_is_confirmed(ct)); This happens when the conntrack entry is created externally before OVS increments net->ct.labels_used. The issue has become more likely since commit fcb1aa51 ("openvswitch: switch to per-action label counting in conntrack"), which changed to use per-action label counting and increment net->ct.labels_used when a flow with ct action is added. Since there’s no straightforward way to fully resolve this issue at the moment, this reverts the commit to avoid breaking existing use cases.

The actions length check is unreliable and produces different results depending on the initial length of the provided netlink attribute and the composition of the actual actions inside of it. For example, a user can add 4088 empty clone() actions without triggering -EMSGSIZE, on attempt to add 4089 such actions the operation will fail with the -EMSGSIZE verdict. However, if another 16 KB of other actions will be *appended* to the previous 4089 clone() actions, the check passes and the flow is successfully installed into the openvswitch datapath. The reason for a such a weird behavior is the way memory is allocated. When ovs_flow_cmd_new() is invoked, it calls ovs_nla_copy_actions(), that in turn calls nla_alloc_flow_actions() with either the actual length of the user-provided actions or the MAX_ACTIONS_BUFSIZE. The function adds the size of the sw_flow_actions structure and then the actually allocated memory is rounded up to the closest power of two. So, if the user-provided actions are larger than MAX_ACTIONS_BUFSIZE, then MAX_ACTIONS_BUFSIZE + sizeof(*sfa) rounded up is 32K + 24 -> 64K. Later, while copying individual actions, we look at ksize(), which is 64K, so this way the MAX_ACTIONS_BUFSIZE check is not actually triggered and the user can easily allocate almost 64 KB of actions. However, when the initial size is less than MAX_ACTIONS_BUFSIZE, but the actions contain ones that require size increase while copying (such as clone() or sample()), then the limit check will be performed during the reserve_sfa_size() and the user will not be allowed to create actions that yield more than 32 KB internally. This is one part of the problem. The other part is that it's not actually possible for the userspace application to know beforehand if the particular set of actions will be rejected or not. Certain actions require more space in the internal representation, e.g. an empty clone() takes 4 bytes in the action list passed in by the user, but it takes 12 bytes in the internal representation due to an extra nested attribute, and some actions require less space in the internal representations, e.g. set(tunnel(..)) normally takes 64+ bytes in the action list provided by the user, but only needs to store a single pointer in the internal implementation, since all the data is stored in the tunnel_info structure instead. And the action size limit is applied to the internal representation, not to the action list passed by the user. So, it's not possible for the userpsace application to predict if the certain combination of actions will be rejected or not, because it is not possible for it to calculate how much space these actions will take in the internal representation without knowing kernel internals. All that is causing random failures in ovs-vswitchd in userspace and inability to handle certain traffic patterns as a result. For example, it is reported that adding a bit more than a 1100 VMs in an OpenStack setup breaks the network due to OVS not being able to handle ARP traffic anymore in some cases (it tries to install a proper datapath flow, but the kernel rejects it with -EMSGSIZE, even though the action list isn't actually that large.) Kernel behavior must be consistent and predictable in order for the userspace application to use it in a reasonable way. ovs-vswitchd has a mechanism to re-direct parts of the traffic and partially handle it in userspace if the required action list is oversized, but that doesn't work properly if we can't actually tell if the action list is oversized or not. Solution for this is to check the size of the user-provided actions instead of the internal representation. This commit just removes the check from the internal part because there is already an implicit size check imposed by the netlink protocol. The attribute can't be larger than 64 KB. Realistically, we could reduce the limit to 32 KB, but we'll be risking to break some existing setups that rely on the fact that it's possible to create nearly 64 KB action lists today. Vast majority of flows in real setups are below 100-ish bytes. So removal of the limit will not change real memory consumption on the system. The absolutely worst case scenario is if someone adds a flow with 64 KB of empty clone() actions. That will yield a 192 KB in the internal representation consuming 256 KB block of memory. However, that list of actions is not meaningful and also a no-op. Real world very large action lists (that can occur for a rare cases of BUM traffic handling) are unlikely to contain a large number of clones and will likely have a lot of tunnel attributes making the internal representation comparable in size to the original action list. So, it should be fine to just remove the limit. Commit in the 'Fixes' tag is the first one that introduced the difference between internal representation and the user-provided action lists, but there were many more afterwards that lead to the situation we have today.

Use addrconf_addr_gen() to generate IPv6 link-local addresses on GRE devices in most cases and fall back to using add_v4_addrs() only in case the GRE configuration is incompatible with addrconf_addr_gen(). GRE used to use addrconf_addr_gen() until commit e5dd7294 ("ip/ip6_gre: use the same logic as SIT interfaces when computing v6LL address") restricted this use to gretap and ip6gretap devices, and created add_v4_addrs() (borrowed from SIT) for non-Ethernet GRE ones. The original problem came when commit 9af28511 ("addrconf: refuse isatap eui64 for INADDR_ANY") made __ipv6_isatap_ifid() fail when its addr parameter was 0. The commit says that this would create an invalid address, however, I couldn't find any RFC saying that the generated interface identifier would be wrong. Anyway, since gre over IPv4 devices pass their local tunnel address to __ipv6_isatap_ifid(), that commit broke their IPv6 link-local address generation when the local address was unspecified. Then commit e5dd7294 ("ip/ip6_gre: use the same logic as SIT interfaces when computing v6LL address") tried to fix that case by defining add_v4_addrs() and calling it to generate the IPv6 link-local address instead of using addrconf_addr_gen() (apart for gretap and ip6gretap devices, which would still use the regular addrconf_addr_gen(), since they have a MAC address). That broke several use cases because add_v4_addrs() isn't properly integrated into the rest of IPv6 Neighbor Discovery code. Several of these shortcomings have been fixed over time, but add_v4_addrs() remains broken on several aspects. In particular, it doesn't send any Router Sollicitations, so the SLAAC process doesn't start until the interface receives a Router Advertisement. Also, add_v4_addrs() mostly ignores the address generation mode of the interface (/proc/sys/net/ipv6/conf/*/addr_gen_mode), thus breaking the IN6_ADDR_GEN_MODE_RANDOM and IN6_ADDR_GEN_MODE_STABLE_PRIVACY cases. Fix the situation by using add_v4_addrs() only in the specific scenario where the normal method would fail. That is, for interfaces that have all of the following characteristics: * run over IPv4, * transport IP packets directly, not Ethernet (that is, not gretap interfaces), * tunnel endpoint is INADDR_ANY (that is, 0), * device address generation mode is EUI64. In all other cases, revert back to the regular addrconf_addr_gen(). Also, remove the special case for ip6gre interfaces in add_v4_addrs(), since ip6gre devices now always use addrconf_addr_gen() instead.

Since rtase_init_ring, which is called within rtase_sw_reset, adds ring entries already present in the ring list back into the list, it causes the ring list to form a cycle. This results in list_for_each_entry_safe failing to find an endpoint during traversal, leading to an error. Therefore, it is necessary to remove the previously added ring_list nodes before calling rtase_init_ring. Fixes: 07960048 ("rtase: Implement net_device_ops") Signed-off-by:
