2017-01-03benet: stricter vxlan offloading check in be_features_checkSabrina Dubroca1-1/+3
When VXLAN offloading is enabled, be_features_check() tries to check if an encapsulated packet is indeed a VXLAN packet. The check is not strict enough, and considers any UDP-encapsulated ethernet frame with a 8-byte tunnel header as being VXLAN. Unfortunately, both GENEVE and VXLAN-GPE have a 8-byte header, so they get through this check. Force the UDP destination port to be the one that has been offloaded to hardware. Without this, GENEVE-encapsulated packets can end up having an incorrect checksum when both a GENEVE and a VXLAN (offloaded) tunnel are configured. This is similar to commit a547224dceed ("mlx4e: Do not attempt to offload VXLAN ports that are unrecognized"). Signed-off-by: Sabrina Dubroca <[email protected]> Signed-off-by: David S. Miller <[email protected]>

2017-01-02igmp: Make igmp group member RFC 3376 compliantMichal Tesar1-1/+6
5.2. Action on Reception of a Query When a system receives a Query, it does not respond immediately. Instead, it delays its response by a random amount of time, bounded by the Max Resp Time value derived from the Max Resp Code in the received Query message. A system may receive a variety of Queries on different interfaces and of different kinds (e.g., General Queries, Group-Specific Queries, and Group-and-Source-Specific Queries), each of which may require its own delayed response. Before scheduling a response to a Query, the system must first consider previously scheduled pending responses and in many cases schedule a combined response. Therefore, the system must be able to maintain the following state: o A timer per interface for scheduling responses to General Queries. o A per-group and interface timer for scheduling responses to Group- Specific and Group-and-Source-Specific Queries. o A per-group and interface list of sources to be reported in the response to a Group-and-Source-Specific Query. When a new Query with the Router-Alert option arrives on an interface, provided the system has state to report, a delay for a response is randomly selected in the range (0, [Max Resp Time]) where Max Resp Time is derived from Max Resp Code in the received Query message. The following rules are then used to determine if a Report needs to be scheduled and the type of Report to schedule. The rules are considered in order and only the first matching rule is applied. 1. If there is a pending response to a previous General Query scheduled sooner than the selected delay, no additional response needs to be scheduled. 2. If the received Query is a General Query, the interface timer is used to schedule a response to the General Query after the selected delay. Any previously pending response to a General Query is canceled. --8<-- Currently the timer is rearmed with new random expiration time for every incoming query regardless of possibly already pending report. Which is not aligned with the above RFE. It also might happen that higher rate of incoming queries can postpone the report after the expiration time of the first query causing group membership loss. Now the per interface general query timer is rearmed only when there is no pending report already scheduled on that interface or the newly selected expiration time is before the already pending scheduled report.

2017-01-01net: socket: don't set sk_uid to garbage value in ->setattr()Eric Biggers1-1/+1
->setattr() was recently implemented for socket files to sync the socket inode's uid to the new 'sk_uid' member of struct sock. It does this by copying over the ia_uid member of struct iattr. However, ia_uid is actually only valid when ATTR_UID is set in ia_valid, indicating that the uid is being changed, e.g. by chown. Other metadata operations such as chmod or utimes leave ia_uid uninitialized. Therefore, sk_uid could be set to a "garbage" value from the stack. Fix this by only copying the uid over when ATTR_UID is set. Fixes: 86741ec25462 ("net: core: Add a UID field to struct sock.")

Attempting to link a device node, named pipe, or socket file into an encrypted directory through rename(2) or link(2) always failed with EPERM. This happened because fscrypt_has_permitted_context() saw that the file was unencrypted and forbid creating the link. This behavior was unexpected because such files are never encrypted; only regular files, directories, and symlinks can be encrypted. To fix this, make fscrypt_has_permitted_context() always return true on special files. This will be covered by a test in my encryption xfstests patchset.

2016-12-29net: ipv4: dst for local input routes should use l3mdev if relevantDavid Ahern1-1/+2
IPv4 output routes already use l3mdev device instead of loopback for dst's if it is applicable. Change local input routes to do the same. This fixes icmp responses for unreachable UDP ports which are directed to the wrong table after commit 9d1a6c4ea43e4 because local_input routes use the loopback device. Moving from ingress device to loopback loses the L3 domain causing responses based on the dst to get to lost.

2016-12-29parisc: Mark cr16 clocksource unstable on SMP systemsHelge Deller1-3/+20
The cr16 interval timer of each CPU is not syncronized to other cr16 timers in other CPUs in a SMP system. So, delay the registration of the cr16 clocksource until all CPUs have been detected and then - if we are on a SMP machine - mark the cr16 clocksource as unstable and lower it's rating before registering it at the clocksource framework. This patch fixes the stalled CPU warnings which we have seen since introduction of the cr16 clocksource. Signed-off-by: Helge Deller <[email protected]> Cc: <[email protected]> # v4.8+

2016-12-29net/mlx4_core: Fix raw qp flow steering rules under SRIOVJack Morgenstein4-23/+33
Demoting simple flow steering rule priority (for DPDK) was achieved by wrapping FW commands MLX4_QP_FLOW_STEERING_ATTACH/DETACH for the PF as well, and forcing the priority to MLX4_DOMAIN_NIC in the wrapper function for the PF and all VFs. In function mlx4_ib_create_flow(), this change caused the main rule creation for the PF to be wrapped, while it left the associated tunnel steering rule creation unwrapped for the PF. This mismatch caused rule deletion failures in mlx4_ib_destroy_flow() for the PF when the detach wrapper function did not find the associated tunnel-steering rule (since creation of that rule for the PF did not go through the wrapper function). Fix this by setting MLX4_QP_FLOW_STEERING_ATTACH/DETACH to be "native" (so that the PF invocation does not go through the wrapper), and perform the required priority demotion for the PF in the mlx4_ib_create_flow() code path.

is_power_of_2 expects unsigned long and we pass u64 max_val_cycles, this will be truncated on 32 bit systems, and the result is not what we were expecting. div_u64 expects u32 as a second argument and we pass max_val_cycles_rounded which is u64 hence it will always be truncated. Fix was tested on both 64 and 32 bit systems and got same results for max_val_cycles and max_val_cycles_rounded.

2016-12-29net/mlx4_core: Use-after-free causes a resource leak in flow-steering detachJack Morgenstein1-2/+4
mlx4_QP_FLOW_STEERING_DETACH_wrapper first removes the steering rule (which results in freeing the rule structure), and then references a field in this struct (the qp number) when releasing the busy-status on the rule's qp. Since this memory was freed, it could reallocated and changed. Therefore, the qp number in the struct may be incorrect, so that we are releasing the incorrect qp. This leaves the rule's qp in the busy state (and could possibly release an incorrect qp as well). Fix this by saving the qp number in a local variable, for use after removing the steering rule.
