Håkon Bugge authored
The number of unsignaled work-requests posted to the IB send queue is tracked by a counter in the rds_ib_connection struct. When it reaches zero, or the caller explicitly asks for it, the send-signaled bit is set in send_flags and the counter is reset. This is performed by the rds_ib_set_wr_signal_state() function. However, this function is not always used which yields inaccurate accounting. This commit fixes this, re-factors a code bloat related to the matter, and makes the actual parameter type to the function consistent.

If the name argument of dev_get_valid_name() contains "%d", it will try to assign it a unit number in __dev__alloc_name() and return either the unit number (>= 0) or an error code (< 0). Considering positive values as error values prevent tun device creations relying this mechanism, therefor we should only consider negative values as errors here.

Previously we did not ensure that a netdev is a representative netdev before dereferencing its private data. This can occur when an upper netdev is created on a representative netdev. This patch corrects this by first ensuring that the netdev is a representative netdev before using it. Checking only switchdev_port_same_parent_id is not sufficient to ensure that we can safely use the netdev. Failing to check that the netdev is also a representative netdev would result in incorrect dereferencing.

To avoid kernel warning "Unhandled message (68)", ignore the CMD_FLUSH_QUEUE_REPLY message for now. As of Leaf v2 firmware version v4.1.844 (2017-02-15), flush tx queue is synchronous. There is a capability bit indicating whether flushing tx queue is synchronous or asynchronous. A proper solution would be to query the device for capabilities. If the synchronous tx flush capability bit is set, we should wait for CMD_FLUSH_QUEUE_REPLY message, while flushing the tx queue.

Commit 9b974202 ("sctp: support ipv6 nonlocal bind") introduced support for the above options as v4 sctp did, so patched sctp_v6_available(). In the v4 implementation it's enough, because sctp_inet_bind_verify() just returns with sctp_v4_available(). However sctp_inet6_bind_verify() has an extra check before that for link-local scope_id, which won't respect the above options. Added the checks before calling ipv6_chk_addr(), but not before the validation of scope_id. before (w/ both options): ./v6test fe80::10 sctp bind failed, errno: 99 (Cannot assign requested address) ./v6test fe80::10 tcp bind success, errno: 0 (Success) after (w/ both options): ./v6test fe80::10 sctp bind success, errno: 0 (Success) Signed-off-by: Laszlo Toth <laszlth@gmail.com> Reviewed-by: Xin Long <lucien.xin@gmail.com> Signed-off-by: David S.

When Tx IRQs are used, txq_bufs_free() can be called from both the Tx path and from NAPI poll(). This led to CPU stalls as if these two tasks (Tx and Poll) are scheduled on two CPUs at the same time, DMA unmapping operations are done on the same txq buffers. This patch adds a check not to call txq_done() from the Tx path if Tx interrupts are used as it does not make sense to do so.

The TSO header buffers are coming from a per cpu pool and should not be unmapped as they are reused. The PPv2 driver was unmapping all descriptors buffers unconditionally.

An independent security researcher, Mohamed Ghannam, has reported this vulnerability to Beyond Security's SecuriTeam Secure Disclosure program. The xfrm_dump_policy_done function expects xfrm_dump_policy to have been called at least once or it will crash. This can be triggered if a dump fails because the target socket's receive buffer is full. This patch fixes it by using the cb->start mechanism to ensure that the initialisation is always done regardless of the buffer situation.

When retransmission on TSQ handler was introduced in the commit f9616c35 ("tcp: implement TSQ for retransmits"), the retransmitted skbs' timestamps were updated on the actual transmission. In the later commit 385e2070 ("tcp: use tp->tcp_mstamp in output path"), it stops being done so. In the commit, the comment says "We try to refresh tp->tcp_mstamp only when necessary", and at present tcp_tsq_handler and tcp_v4_mtu_reduced applies to this. About the latter, it's okay since it's rare enough. About the former, even though possible retransmissions on the tasklet comes just after the destructor run in NET_RX softirq handling, the time between them could be nonnegligibly large to the extent that tcp_rack_advance or rto rearming be affected if other (remaining) RX, BLOCK and (preceding) TASKLET sofirq handlings are unexpectedly heavy. So in the same way as tcp_write_timer_handler does, doing tcp_mstamp_refresh ensures the accuracy of algorithms relying on it.

This is the possible reason for different hard to reproduce problems on my ARMv7-SMP test system. The symptoms are in recent kernels imprecise external aborts, and in older kernels various kinds of network stalls and unexpected page allocation failures. My testing indicates that the trouble started between v4.5 and v4.6 and prevails up to v4.14. Using the dirty_tx before acquiring the spin lock is clearly wrong and was first introduced with v4.6.

When syzkaller team brought us a C repro for the crash [1] that had been reported many times in the past, I finally could find the root cause. If FlowLabel info is merged by fl6_merge_options(), we leave part of the opt_space storage provided by udp/raw/l2tp with random value in opt_space.tot_len, unless a control message was provided at sendmsg() time. Then ip6_setup_cork() would use this random value to perform a kzalloc() call. Undefined behavior and crashes. Fix is to properly set tot_len in fl6_merge_options() At the same time, we can also avoid consuming memory and cpu cycles to clear it, if every option is copied via a kmemdup(). This is the change in ip6_setup_cork().

If an Ethernet PHY is initialized before the interrupt controller it is connected to, a message like the following is printed: irq: no irq domain found for /interrupt-controller@e61c0000 ! However, the actual error is ignored, leading to a non-functional (POLL) PHY interrupt later: Micrel KSZ8041RNLI ee700000.ethernet-ffffffff:01: attached PHY driver [Micrel KSZ8041RNLI] (mii_bus:phy_addr=ee700000.ethernet-ffffffff:01, irq=POLL) Depending on whether the PHY driver will fall back to polling, Ethernet may or may not work. To fix this: 1. Switch of_mdiobus_register_phy() from irq_of_parse_and_map() to of_irq_get(). Unlike the former, the latter returns -EPROBE_DEFER if the interrupt controller is not yet available, so this condition can be detected. Other errors are handled the same as before, i.e. use the passed mdio->irq[addr] as interrupt. 2. Propagate and handle errors from of_mdiobus_register_phy() and of_mdiobus_register_device().

Jiri Pirko says: ==================== mlxsw: spectrum: Configure TTL of "inherit" for offloaded tunnels Petr says: Currently mlxsw only offloads tunnels that are configured with TTL of "inherit" (which is the default). However, Spectrum defaults to 255 and the driver neglects to change the configuration. Thus the tunnel packets from offloaded tunnels always have TTL of 255, even though tunnels with explicit TTL of 255 are never actually offloaded. To fix this, introduce support for TIGCR, the register that keeps the related bits of global tunnel configuration, and use it on first offload to properly configure inheritance of TTL of tunnel packets from overlay packets. ==================== Signed-off-by: David S.

Spectrum tunnels do not default to ttl of "inherit" like the Linux ones do. Configure TIGCR on router init so that the TTL of tunnel packets is copied from the overlay packets.

Commit 9cab88726929605 ("net: ethtool: Add back transceiver type") restores the transceiver type to struct ethtool_link_settings and convert_link_ksettings_to_legacy_settings() but forgets to remove the error check for the same in convert_legacy_settings_to_link_ksettings(). This prevents older versions of ethtool to change link settings. # ethtool --version ethtool version 3.16 # ethtool -s eth0 autoneg on speed 100 duplex full Cannot set new settings: Invalid argument not setting speed not setting duplex not setting autoneg While newer versions of ethtool works. # ethtool --version ethtool version 4.10 # ethtool -s eth0 autoneg on speed 100 duplex full [ 57.703268] sh-eth ee700000.ethernet eth0: Link is Down [ 59.618227] sh-eth ee700000.ethernet eth0: Link is Up - 100Mbps/Full - flow control rx/tx Fixes: 19cab887 ("net: ethtool: Add back transceiver type") Signed-off-by: Niklas Söderlund <niklas.soderlund+renesas@ragnatech.se> Reported-by: Renjith R V <renjith.rv@quest-global.com> Tested-by: Geert Uytterhoeven <geert+renesas@glider.be> Signed-off-by: David S.
