RGMII_MODE_EN bit was defined to 0, while it is actually 6. It was not much of a problem on older designs where this was a no-op, and the RGMII data-path would always be enabled, but newer GENET controllers need to explicitely enable their RGMII data-pad using this bit. Signed-off-by:

If the 'next' pointer of the last fragment buffer in a message is not zeroed before reassembly, we risk ending up with a corrupt message, since the reassembly function itself isn't doing this. Currently, when a buffer is retrieved from the deferred queue of the broadcast link, the next pointer is not cleared, with the result as described above. This commit corrects this, and thereby fixes a bug that may occur when long broadcast messages are transmitted across dual interfaces. The bug has been present since 40ba3cdf ("tipc: message reassembly using fragment chain") This commit should be applied to both net and net-next. Signed-off-by:

There are several issues in fst_add_one() and fst_init_card(): - invalid pointer dereference at card->ports[card->nports - 1] if register_hdlc_device() fails for the first port in fst_init_card(); - fst_card_array overflow at fst_card_array[no_of_cards_added] because there is no checks for array overflow; - use after free because pointer to deallocated card is left in fst_card_array if something fails after fst_card_array[no_of_cards_added] = card; - several leaks on failure paths in fst_add_one(). The patch fixes all the issues and makes code more readable. Found by Linux Driver Verification project (linuxtesting.org). Signed-off-by:

netlink_dump() returns a negative errno value on error. Until now, netlink_recvmsg() directly recorded that negative value in sk->sk_err, but that's wrong since sk_err takes positive errno values. (This manifests as userspace receiving a positive return value from the recv() system call, falsely indicating success.) This bug was introduced in the commit that started checking the netlink_dump() return value, commit b44d211e (netlink: handle errors from netlink_dump()). Multithreaded Netlink dumps are one way to trigger this behavior in practice, as described in the commit message for the userspace workaround posted here: http://openvswitch.org/pipermail/dev/2014-June/042339.html This commit also fixes the same bug in netlink_poll(), introduced in commit cd1df525 (netlink: add flow control for memory mapped I/O).

As reported by Maggie Mae Roxas, the mvneta driver doesn't behave properly in 10 Mbit/s mode. This is due to a misconfiguration of the MVNETA_GMAC_AUTONEG_CONFIG register: bit MVNETA_GMAC_CONFIG_MII_SPEED must be set for a 100 Mbit/s speed, but cleared for a 10 Mbit/s speed, which the driver was not properly doing. This commit adjusts that by setting the MVNETA_GMAC_CONFIG_MII_SPEED bit only in 100 Mbit/s mode, and relying on the fact that all the speed related bits of this register are cleared at the beginning of the mvneta_adjust_link() function. This problem exists since c5aff182 ("net: mvneta: driver for Marvell Armada 370/XP network unit") which is the commit that introduced the mvneta driver in the kernel.

This patch fixes 3 similar bugs where incoming packets might be routed into wrong non-wildcard tunnels: 1) Consider the following setup: ip address add 1.1.1.1/24 dev eth0 ip address add 1.1.1.2/24 dev eth0 ip tunnel add ipip1 remote 2.2.2.2 local 1.1.1.1 mode ipip dev eth0 ip link set ipip1 up Incoming ipip packets from 2.2.2.2 were routed into ipip1 even if it has dst = 1.1.1.2. Moreover even if there was wildcard tunnel like ip tunnel add ipip0 remote 2.2.2.2 local any mode ipip dev eth0 but it was created before explicit one (with local 1.1.1.1), incoming ipip packets with src = 2.2.2.2 and dst = 1.1.1.2 were still routed into ipip1. Same issue existed with all tunnels that use ip_tunnel_lookup (gre, vti) 2) ip address add 1.1.1.1/24 dev eth0 ip tunnel add ipip1 remote 2.2.146.85 local 1.1.1.1 mode ipip dev eth0 ip link set ipip1 up Incoming ipip packets with dst = 1.1.1.1 were routed into ipip1, no matter what src address is. Any remote ip address which has ip_tunnel_hash = 0 raised this issue, 2.2.146.85 is just an example, there are more than 4 million of them. And again, wildcard tunnel like ip tunnel add ipip0 remote any local 1.1.1.1 mode ipip dev eth0 wouldn't be ever matched if it was created before explicit tunnel like above. Gre & vti tunnels had the same issue. 3) ip address add 1.1.1.1/24 dev eth0 ip tunnel add gre1 remote 2.2.146.84 local 1.1.1.1 key 1 mode gre dev eth0 ip link set gre1 up Any incoming gre packet with key = 1 were routed into gre1, no matter what src/dst addresses are. Any remote ip address which has ip_tunnel_hash = 0 raised the issue, 2.2.146.84 is just an example, there are more than 4 million of them. Wildcard tunnel like ip tunnel add gre2 remote any local any key 1 mode gre dev eth0 wouldn't be ever matched if it was created before explicit tunnel like above. All this stuff happened because while looking for a wildcard tunnel we didn't check that matched tunnel is a wildcard one. Fixed. Signed-off-by:Dmitry Popov <ixaphire@qrator.net> Signed-off-by:

Since commit 37e22164 ("tipc: rename and move message reassembly function") reassembly of long broadcast messages has been broken. This is because we test for a non-NULL return value of the *buf parameter as criteria for succesful reassembly. However, this parameter is left defined even after reception of the first fragment, when reassebly is still incomplete. This leads to a kernel crash as soon as a the first fragment of a long broadcast message is received. We fix this with this commit, by implementing a stricter behavior of the function and its return values. This commit should be applied to both net and net-next. Signed-off-by:

In xennet_disconnect_backend(), netif_carrier_off() was called once per queue when it needs to only be called once. The queue locking around the netif_carrier_off() call looked very odd. I think they were supposed to synchronize any NAPI instances with the expectation that no further NAPI instances would be scheduled because of the carrier being off (see the check in xennet_rx_interrupt()). But I can't easily tell if this works correctly. Instead, add a napi_synchronize() call after disabling the interrupts. This is obviously correct as with no Rx interrupts, no further NAPI instances will be scheduled. Signed-off-by:

The nesting of the per-queue rx_lock and tx_lock in xennet_connect() is confusing to both humans and lockdep. The locking is safe because this is the only place where the locks are nested in this way but lockdep still warns. Instead of adding the missing lockdep annotations, refactor the locking to avoid the confusing nesting. This is still safe, because the xenbus connection state changes are all serialized by the xenwatch thread. Signed-off-by:

The undo code assumes that, upon entering loss recovery, TCP 1) always retransmit something 2) the retransmission never fails locally (e.g., qdisc drop) so undo_marker is set in tcp_enter_recovery() and undo_retrans is incremented only when tcp_retransmit_skb() is successful. When the assumption is broken because TCP's cwnd is too small to retransmit or the retransmit fails locally. The next (DUP)ACK would incorrectly revert the cwnd and the congestion state in tcp_try_undo_dsack() or tcp_may_undo(). Subsequent (DUP)ACKs may enter the recovery state. The sender repeatedly enter and (incorrectly) exit recovery states if the retransmits continue to fail locally while receiving (DUP)ACKs. The fix is to initialize undo_retrans to -1 and start counting on the first retransmission. Always increment undo_retrans even if the retransmissions fail locally because they couldn't cause DSACKs to undo the cwnd reduction. Signed-off-by:

A bug was introduced in NETDEV_CHANGE notifier sequence causing the arp table to be sometimes spuriously cleared (including manual arp entries marked permanent), upon network link carrier changes. The changed argument for the notifier was applied only to a single caller of NETDEV_CHANGE, missing among others netdev_state_change(). So upon net_carrier events induced by the network, which are triggering a call to netdev_state_change(), arp_netdev_event() would decide whether to clear or not arp cache based on random/junk stack values (a kind of read buffer overflow).

In process_backlog the input_pkt_queue is only checked once for new packets and quota is artificially reduced to reflect precisely the number of packets on the input_pkt_queue so that the loop exits appropriately. This patches changes the behavior to be more straightforward and less convoluted. Packets are processed until either the quota is met or there are no more packets to process. This patch seems to provide a small, but noticeable performance improvement. The performance improvement is a result of staying in the process_backlog loop longer which can reduce number of IPI's.

Some older router implementations still send Fragmentation Needed errors with the Next-Hop MTU field set to zero. This is explicitly described as an eventuality that hosts must deal with by the standard (RFC 1191) since older standards specified that those bits must be zero. Linux had a generic (for all of IPv4) implementation of the algorithm described in the RFC for searching a list of MTU plateaus for a good value. Commit 46517008 ("ipv4: Kill ip_rt_frag_needed().") removed this as part of the changes to remove the routing cache. Subsequently any Fragmentation Needed packet with a zero Next-Hop MTU has been discarded without being passed to the per-protocol handlers or notifying userspace for raw sockets. When there is a router which does not implement RFC 1191 on an MTU limited path then this results in stalled connections since large packets are discarded and the local protocols are not notified so they never attempt to lower the pMTU. One example I have seen is an OpenBSD router terminating IPSec tunnels. It's worth pointing out that this case is distinct from the BSD 4.2 bug which incorrectly calculated the Next-Hop MTU since the commit in question dismissed that as a valid concern. All of the per-protocols handlers implement the simple approach from RFC 1191 of immediately falling back to the minimum value. Although this is sub-optimal it is vastly preferable to connections hanging indefinitely. Remove the Next-Hop MTU != 0 check and allow such packets to follow the normal path.

Firmware folks seem say that this flag can make trouble. Drop it. The advantage of CTS to self is that it slightly reduces the cost of the protection, but make the protection less reliable. Cc: <stable@vger.kernel.org> [3.13+] Signed-off-by:Emmanuel Grumbach <emmanuel.grumbach@intel.com>
