According to rfc7496 section 4.3 or 4.4: sprstat_policy: This parameter indicates for which PR-SCTP policy the user wants the information. It is an error to use SCTP_PR_SCTP_NONE in sprstat_policy. If SCTP_PR_SCTP_ALL is used, the counters provided are aggregated over all supported policies. We change to dump pr_assoc and pr_stream all status by SCTP_PR_SCTP_ALL instead, and return error for SCTP_PR_SCTP_NONE, as it also said "It is an error to use SCTP_PR_SCTP_NONE in sprstat_policy. " Fixes: 826d253d ("sctp: add SCTP_PR_ASSOC_STATUS on sctp sockopt") Fixes: d229d48d ("sctp: add SCTP_PR_STREAM_STATUS sockopt for prsctp") Reported-by:Ying Xu <yinxu@redhat.com> Signed-off-by:

Jakub Kicinski says: ==================== nfp: fix pedit set action offloads Pieter says: This set fixes set actions when using multiple pedit actions with partial masks and with multiple keys per pedit action. Additionally it fixes set ipv6 pedit action offloads when using it in combination with other header keys. The problem would only trigger if one combines multiple pedit actions of the same type with partial masks, e.g.: $ tc filter add dev netdev protocol ip parent ffff: \ flower indev netdev \ ip_proto tcp \ action pedit ex munge \ ip src set 11.11.11.11 retain 65535 munge \ ip src set 22.22.22.22 retain 4294901760 pipe \ csum ip and tcp pipe \ mirred egress redirect dev netdev ==================== Signed-off-by: -

Previously when populating the set ipv6 address action, we incorrectly made use of pedit's key index to determine which 32bit word should be set. We now calculate which word has been selected based on the offset provided by the pedit action. Fixes: 354b82bb ("nfp: add set ipv6 source and destination address") Signed-off-by:

Previously we only allowed a single header key per pedit action to change the header. This used to result in the last header key in the pedit action to overwrite previous headers. We now keep track of them and allow multiple header keys per pedit action.

Fix a missing call to rxrpc_put_peer() on the main path through the rxrpc_error_report() function. This manifests itself as a ref leak whenever an ICMP packet or other error comes in. In commit f3344303, the hand-off of the ref to a work item was removed and was not replaced with a put. Fixes: f3344303 ("rxrpc: Fix error distribution") Signed-off-by:

Other than asoc pmtu sync from all transports, sctp_assoc_sync_pmtu is also processing transport pmtu_pending by icmp packets. But it's meaningless to use sctp_dst_mtu(t->dst) as new pmtu for a transport. The right pmtu value should come from the icmp packet, and it would be saved into transport->mtu_info in this patch and used later when the pmtu sync happens in sctp_sendmsg_to_asoc or sctp_packet_config. Besides, without this patch, as pmtu can only be updated correctly when receiving a icmp packet and no place is holding sock lock, it will take long time if the sock is busy with sending packets. Note that it doesn't process transport->mtu_info in .release_cb(), as there is no enough information for pmtu update, like for which asoc or transport. It is not worth traversing all asocs to check pmtu_pending. So unlike tcp, sctp does this in tx path, for which mtu_info needs to be atomic_t. Signed-off-by:

Commit db65f35f ("net: fec: add support of ethtool get_regs") introduce ethool "--register-dump" interface to dump all FEC registers. But not all silicon implementations of the Freescale FEC hardware module have the FRBR (FIFO Receive Bound Register) and FRSR (FIFO Receive Start Register) register, so we should not be trying to dump them on those that don't. To fix it we create a quirk flag, FEC_QUIRK_HAS_RFREG, and check it before dump those RX FIFO registers. Signed-off-by:

syzbot found a use-after-free in inet6_mc_check [1] The problem here is that inet6_mc_check() uses rcu and read_lock(&iml->sflock) So the fact that ip6_mc_leave_src() is called under RTNL and the socket lock does not help us, we need to acquire iml->sflock in write mode. In the future, we should convert all this stuff to RCU.

The binding table's 'cluster_scope' list is rcu protected to handle races between threads changing the list and those traversing the list at the same moment. We have now found that the function named_distribute() uses the regular list_for_each() macro to traverse the said list. Likewise, the function tipc_named_withdraw() is removing items from the same list using the regular list_del() call. When these two functions execute in parallel we see occasional crashes. This commit fixes this by adding the missing _rcu() suffixes. Signed-off-by:

When commit 27097255 ("[IPV6]: ROUTE: Add Router Reachability Probing (RFC4191).") introduced router probing, the rt6_probe() function required that a neighbour entry existed. This neighbour entry is used to record the timestamp of the last probe via the ->updated field. Later, commit 2152caea ("ipv6: Do not depend on rt->n in rt6_probe().") removed the requirement for a neighbour entry. Neighbourless routes skip the interval check and are not rate-limited. This patch adds rate-limiting for neighbourless routes, by recording the timestamp of the last probe in the fib6_info itself. Fixes: 2152caea ("ipv6: Do not depend on rt->n in rt6_probe().")

In the commit referred to below we added link tolerance as an additional criteria for declaring broadcast transmission "stale" and resetting the unicast links to the affected node. Unfortunately, this 'improvement' introduced two bugs, which each and one alone cause only limited problems, but combined lead to seemingly stochastic unicast link resets, depending on the amount of broadcast traffic transmitted. The first issue, a missing initialization of the 'tolerance' field of the receiver broadcast link, was recently fixed by commit 047491ea ("tipc: set link tolerance correctly in broadcast link"). Ths second issue, where we omit to reset the 'stale_cnt' field of the same link after a 'stale' period is over, leads to this counter accumulating over time, and in the absence of the 'tolerance' criteria leads to the above described symptoms. This commit adds the missing initialization. Fixes: a4dc70d4 ("tipc: extend link reset criteria for stale packet retransmission") Signed-off-by:

WHen an llc sock is added into the sk_laddr_hash of an llc_sap, it is not marked with SOCK_RCU_FREE. This causes that the sock could be freed while it is still being read by __llc_lookup_established() with RCU read lock. sock is refcounted, but with RCU read lock, nothing prevents the readers getting a zero refcnt.

In dev_ethtool(), the eth command 'ethcmd' is firstly copied from the use-space buffer 'useraddr' and checked to see whether it is ETHTOOL_PERQUEUE. If yes, the sub-command 'sub_cmd' is further copied from the user space. Otherwise, 'sub_cmd' is the same as 'ethcmd'. Next, according to 'sub_cmd', a permission check is enforced through the function ns_capable(). For example, the permission check is required if 'sub_cmd' is ETHTOOL_SCOALESCE, but it is not necessary if 'sub_cmd' is ETHTOOL_GCOALESCE, as suggested in the comment "Allow some commands to be done by anyone". The following execution invokes different handlers according to 'ethcmd'. Specifically, if 'ethcmd' is ETHTOOL_PERQUEUE, ethtool_set_per_queue() is called. In ethtool_set_per_queue(), the kernel object 'per_queue_opt' is copied again from the user-space buffer 'useraddr' and 'per_queue_opt.sub_command' is used to determine which operation should be performed. Given that the buffer 'useraddr' is in the user space, a malicious user can race to change the sub-command between the two copies. In particular, the attacker can supply ETHTOOL_PERQUEUE and ETHTOOL_GCOALESCE to bypass the permission check in dev_ethtool(). Then before ethtool_set_per_queue() is called, the attacker changes ETHTOOL_GCOALESCE to ETHTOOL_SCOALESCE. In this way, the attacker can bypass the permission check and execute ETHTOOL_SCOALESCE. This patch enforces a check in ethtool_set_per_queue() after the second copy from 'useraddr'. If the sub-command is different from the one obtained in the first copy in dev_ethtool(), an error code EINVAL will be returned.

In ethtool_get_rxnfc(), the eth command 'cmd' is compared against 'ETHTOOL_GRXFH' to see whether it is necessary to adjust the variable 'info_size'. Then the whole structure of 'info' is copied from the user-space buffer 'useraddr' with 'info_size' bytes. In the following execution, 'info' may be copied again from the buffer 'useraddr' depending on the 'cmd' and the 'info.flow_type'. However, after these two copies, there is no check between 'cmd' and 'info.cmd'. In fact, 'cmd' is also copied from the buffer 'useraddr' in dev_ethtool(), which is the caller function of ethtool_get_rxnfc(). Given that 'useraddr' is in the user space, a malicious user can race to change the eth command in the buffer between these copies. By doing so, the attacker can supply inconsistent data and cause undefined behavior because in the following execution 'info' will be passed to ops->get_rxnfc(). This patch adds a necessary check on 'info.cmd' and 'cmd' to confirm that they are still same after the two copies in ethtool_get_rxnfc(). Otherwise, an error code EINVAL will be returned.

That breaks the MSI-X interrupt. Therefore, we can only fall back to MSI interrupt to fix the issue at that time. However, there is a commit which resolves the drivers getting nothing in PCI BAR=4 after system resumes. It is 04cb3ae895d7 "PCI: Reprogram bridge prefetch registers on resume" by Daniel Drake. After apply the patch, the ethernet adapter works fine before suspend and after resume. So, we can revert the workaround after the commit "PCI: Reprogram bridge prefetch registers on resume" is merged into main tree. This patch reverts commit 7bb05b85 "r8169: don't use MSI-X on RTL8106e".

Fix a leak of afs_server structs. The routine that installs them in the various lookup lists and trees gets a ref on leaving the function, whether it added the server or a server already exists. It shouldn't increment the refcount if it added the server. The effect of this that "rmmod kafs" will hang waiting for the leaked server to become unused.

Access to the list of cells by /proc/net/afs/cells has a couple of problems: (1) It should be checking against SEQ_START_TOKEN for the keying the header line. (2) It's only holding the RCU read lock, so it can't just walk over the list without following the proper RCU methods. Fix these by using an hlist instead of an ordinary list and using the appropriate accessor functions to follow it with RCU. Since the code that adds a cell to the list must also necessarily change, sort the list on insertion whilst we're at it. Fixes: 989782dc ("afs: Overhaul cell database management") Signed-off-by: -

The previous patch introduced very large kernel stack usage and a Makefile change to hide the warning about it. From what I can tell, a number of things went wrong here: - The BCH_MAX_T constant was set to the maximum value for 'n', not the maximum for 't', which is much smaller. - The stack usage is actually larger than the entire kernel stack on some architectures that can use 4KB stacks (m68k, sh, c6x), which leads to an immediate overrun. - The justification in the patch description claimed that nothing changed, however that is not the case even without the two points above: the configuration is machine specific, and most boards never use the maximum BCH_ECC_WORDS() length but instead have something much smaller. That maximum would only apply to machines that use both the maximum block size and the maximum ECC strength. The largest value for 't' that I could find is '32', which in turn leads to a 60 byte array instead of 2048 bytes. Making it '64' for future extension seems also worthwhile, with 120 bytes for the array. Anything larger won't fit into the OOB area on NAND flash. With that changed, the warning can be enabled again. Only linux-4.19+ contains the breakage, so this is only needed as a stable backport if it does not make it into the release.
