Since now, the table with same id in multiple netnamespaces were squashed to a single virtual router. That is not only incorrect, it also causes error messages when trying to use RALUE register to do double remove of FIB entries, like this one: mlxsw_spectrum 0000:03:00.0: EMAD reg access failed (tid=facb831c00007b20,reg_id=8013(ralue),type=write,status=7(bad parameter)) Since we don't allow ports to change namespaces (NETIF_F_NETNS_LOCAL), and the infrastructure is not yet prepared to handle netnamespaces, just ignore FIB notification events for non-init namespaces. That is clear to do since we don't need to offload them. Fixes: b45f64d1 ("mlxsw: spectrum_router: Use FIB notifications instead of switchdev calls") Signed-off-by:

__neigh_create function works in a different way than assumed. It passes "n" as a parameter to ndo_neigh_construct. But this "n" might be destroyed right away before __neigh_create() returns in case there is already another neighbour struct in the hashtable with the same dev and primary key. That is not expected by mlxsw_sp_router_neigh_construct() and the stored "n" points to freed memory, eventually leading to crash. Fix this by doing tight 1:1 coupling between neighbour struct and internal driver neigh_entry. That allows to narrow down the key in internal driver hashtable to do lookups by "n" only.

Pablo Neira Ayuso says: ==================== Netfilter fixes for net The following patchset contains a larger than usual batch of Netfilter fixes for your net tree. This series contains a mixture of old bugs and recently introduced bugs, they are: 1) Fix a crash when using nft_dynset with nft_set_rbtree, which doesn't support the set element updates from the packet path. From Liping Zhang. 2) Fix leak when nft_expr_clone() fails, from Liping Zhang. 3) Fix a race when inserting new elements to the set hash from the packet path, also from Liping. 4) Handle segmented TCP SIP packets properly, basically avoid that the INVITE in the allow header create bogus expectations by performing stricter SIP message parsing, from Ulrich Weber. 5) nft_parse_u32_check() should return signed integer for errors, from John Linville. 6) Fix wrong allocation instead of connlabels, allocate 16 instead of 32 bytes, from Florian Westphal. 7) Fix compilation breakage when building the ip_vs_sync code with CONFIG_OPTIMIZE_INLINING on x86, from Arnd Bergmann. 8) Destroy the new set if the transaction object cannot be allocated, also from Liping Zhang. 9) Use device to route duplicated packets via nft_dup only when set by the user, otherwise packets may not follow the right route, again from Liping. 10) Fix wrong maximum genetlink attribute definition in IPVS, from WANG Cong. 11) Ignore untracked conntrack objects from xt_connmark, from Florian Westphal. 12) Allow to use conntrack helpers that are registered NFPROTO_UNSPEC via CT target, otherwise we cannot use the h.245 helper, from Florian. 13) Revisit garbage collection heuristic in the new workqueue-based timer approach for conntrack to evict objects earlier, again from Florian. 14) Fix crash in nf_tables when inserting an element into a verdict map, from Liping Zhang. ==================== Signed-off-by: -

Use the opt_* fields to determine the starting point for negotiating the number of tx/rx completion queues with the vnic server. These contain the number of queues that the vnic server estimates that it will be able to allocate. While renegotiation may still occur, using the opt_* fields will reduce the number of times this needs to happen and will prevent driver probe timeout on systems using large numbers of ibmvnic client devices per vnic port.

We received two reports of BUG_ON in bnad_txcmpl_process() where hw_consumer_index appeared to be ahead of producer_index. Out of order write/read of these variables could explain these reports. bnad_start_xmit(), as a producer of tx descriptors, has a few memory barriers sprinkled around writes to producer_index and the device's doorbell but they're not paired with anything in bnad_txcmpl_process(), a consumer. Since we are synchronizing with a device, we must use mandatory barriers, not smp_*. Also, I didn't see the purpose of the last smp_mb() in bnad_start_xmit(). Signed-off-by:

Routes can specify an mtu explicitly or inherit the mtu from the underlying device - this inheritance is implemented in dst->ops->mtu handlers ip6_mtu() and ip6_blackhole_mtu(). Currently changing the mtu of a device adds mtu explicitly to routes using that device. ie. # ip link set dev lo mtu 65536 # ip -6 route add local 2000::1 dev lo # ip -6 route get 2000::1 local 2000::1 dev lo table local src ... metric 1024 pref medium # ip link set dev lo mtu 65535 # ip -6 route get 2000::1 local 2000::1 dev lo table local src ... metric 1024 mtu 65535 pref medium # ip link set dev lo mtu 65536 # ip -6 route get 2000::1 local 2000::1 dev lo table local src ... metric 1024 mtu 65536 pref medium # ip -6 route del local 2000::1 After this patch the route entry no longer changes unless it already has an mtu. There is no need: this inheritance is already done in ip6_mtu() # ip link set dev lo mtu 65536 # ip -6 route add local 2000::1 dev lo # ip -6 route add local 2000::2 dev lo mtu 2000 # ip -6 route get 2000::1; ip -6 route get 2000::2 local 2000::1 dev lo table local src ... metric 1024 pref medium local 2000::2 dev lo table local src ... metric 1024 mtu 2000 pref medium # ip link set dev lo mtu 65535 # ip -6 route get 2000::1; ip -6 route get 2000::2 local 2000::1 dev lo table local src ... metric 1024 pref medium local 2000::2 dev lo table local src ... metric 1024 mtu 2000 pref medium # ip link set dev lo mtu 1501 # ip -6 route get 2000::1; ip -6 route get 2000::2 local 2000::1 dev lo table local src ... metric 1024 pref medium local 2000::2 dev lo table local src ... metric 1024 mtu 1501 pref medium # ip link set dev lo mtu 65536 # ip -6 route get 2000::1; ip -6 route get 2000::2 local 2000::1 dev lo table local src ... metric 1024 pref medium local 2000::2 dev lo table local src ... metric 1024 mtu 65536 pref medium # ip -6 route del local 2000::1 # ip -6 route del local 2000::2 This is desirable because changing device mtu and then resetting it to the previous value shouldn't change the user visible routing table.

Do not send the next message in sendmmsg for partial sendmsg invocations. sendmmsg assumes that it can continue sending the next message when the return value of the individual sendmsg invocations is positive. It results in corrupting the data for TCP, SCTP, and UNIX streams. For example, sendmmsg([["abcd"], ["efgh"]]) can result in a stream of "aefgh" if the first sendmsg invocation sends only the first byte while the second sendmsg goes through. Datagram sockets either send the entire datagram or fail, so this patch affects only sockets of type SOCK_STREAM and SOCK_SEQPACKET.

Nicolas Dichtel says: After commit b87a2f91 ("netfilter: conntrack: add gc worker to remove timed-out entries"), netlink conntrack deletion events may be sent with a huge delay. Nicolas further points at this line: goal = min(nf_conntrack_htable_size / GC_MAX_BUCKETS_DIV, GC_MAX_BUCKETS); and indeed, this isn't optimal at all. Rationale here was to ensure that we don't block other work items for too long, even if nf_conntrack_htable_size is huge. But in order to have some guarantee about maximum time period where a scan of the full conntrack table completes we should always use a fixed slice size, so that once every N scans the full table has been examined at least once. We also need to balance this vs. the case where the system is either idle (i.e., conntrack table (almost) empty) or very busy (i.e. eviction happens from packet path). So, after some discussion with Nicolas: 1. want hard guarantee that we scan entire table at least once every X s -> need to scan fraction of table (get rid of upper bound) 2. don't want to eat cycles on idle or very busy system -> increase interval if we did not evict any entries 3. don't want to block other worker items for too long -> make fraction really small, and prefer small scan interval instead 4. Want reasonable short time where we detect timed-out entry when system went idle after a burst of traffic, while not doing scans all the time. -> Store next gc scan in worker, increasing delays when no eviction happened and shrinking delay when we see timed out entries. The old gc interval is turned into a max number, scans can now happen every jiffy if stale entries are present. Longest possible time period until an entry is evicted is now 2 minutes in worst case (entry expires right after it was deemed 'not expired'). Reported-by:

The (percpu) untracked conntrack entries can end up with nonzero connmarks. The 'untracked' conntrack objects are merely a way to distinguish INVALID (i.e. protocol connection tracker says payload doesn't meet some requirements or packet was never seen by the connection tracking code) from packets that are intentionally not tracked (some icmpv6 types such as neigh solicitation, or by using 'iptables -j CT --notrack' option). Untracked conntrack objects are implementation detail, we might as well use invalid magic address instead to tell INVALID and UNTRACKED apart. Check skb->nfct for untracked dummy and behave as if skb->nfct is NULL. Reported-by:

The display of /proc/net/route has had a couple issues due to the fact that when I originally rewrote most of fib_trie I made it so that the iterator was tracking the next value to use instead of the current. In addition it had an off by 1 error where I was tracking the first piece of data as position 0, even though in reality that belonged to the SEQ_START_TOKEN. This patch updates the code so the iterator tracks the last reported position and key instead of the next expected position and key. In addition it shifts things so that all of the leaves start at 1 instead of trying to report leaves starting with offset 0 as being valid. With these two issues addressed this should resolve any off by one errors that were present in the display of /proc/net/route.

In map_create(), we first find and create the map, then once that suceeded, we charge it to the user's RLIMIT_MEMLOCK, and then fetch a new anon fd through anon_inode_getfd(). The problem is, once the latter fails f.e. due to RLIMIT_NOFILE limit, then we only destruct the map via map->ops->map_free(), but without uncharging the previously locked memory first. That means that the user_struct allocation is leaked as well as the accounted RLIMIT_MEMLOCK memory not released. Make the label names in the fix consistent with bpf_prog_load().

Commit a6ed3ea6 ("bpf: restore behavior of bpf_map_update_elem") added an extra per-cpu reserve to the hash table map to restore old behaviour from pre prealloc times. When non-prealloc is in use for a map, then problem is that once a hash table extra element has been linked into the hash-table, and the hash table is destroyed due to refcount dropping to zero, then htab_map_free() -> delete_all_elements() will walk the whole hash table and drop all elements via htab_elem_free(). The problem is that the element from the extra reserve is first fed to the wrong backend allocator and eventually freed twice.

sctp_wait_for_connect() currently already holds the asoc to keep it alive during the sleep, in case another thread release it. But Andrey Konovalov and Dmitry Vyukov reported an use-after-free in such situation. Problem is that __sctp_connect() doesn't get a ref on the asoc and will do a read on the asoc after calling sctp_wait_for_connect(), but by then another thread may have closed it and the _put on sctp_wait_for_connect will actually release it, causing the use-after-free. Fix is, instead of doing the read after waiting for the connect, do it before so, and avoid this issue as the socket is still locked by then. There should be no issue on returning the asoc id in case of failure as the application shouldn't trust on that number in such situations anyway. This issue doesn't exist in sctp_sendmsg() path.
