2018-02-06vlib: epoll on worker threadsDamjan Marion6-1/+10
This patch teaches worer threads to sleep and to be waken up by kernel if there is activity on file desctiptors assigned to that thread. It also adds counters to epoll file descriptors and new debug cli 'show unix file'. Change-Id: Iaf67869f4aa88ff5b0a08982e1c08474013107c4 Signed-off-by: Damjan Marion <damarion@cisco.com>
2018-02-06SCTP: handling of heartbeating and max-retransmitsMarco Varlese4-57/+164
This patch address the need to send/receive heartbeats between peers. At the same time, the number of unacked heartbeats is tracked and when the peer requests to send DATA to the remote-peer the value of unacked heartbeats needs to be checked against the maximum value allowed for retransmissions. If the unacked heartbeats value is higher then the remote-peer is considered unreachable and the connetion needs to be shutdown.

2018-02-01Out-of-order data chunks handling and moreMarco Varlese4-69/+235
This patch addresses the need to handle out-of-order data chunks received by a peer. To do that effectively, we had to add the handling of data chunks flags (E/B/U bit) to understand whether the stream is fragmenting user-message data and in that case if a fragment is the FIRST/MIDDLE/LAST one of a transmission. The same patch also addresses the security requirement to have a HMAC calculated and incorporated in the INIT_ACK and COOKIE_ECHO chunks. The algorithm used is the HMAC-SHA1.

2018-02-01vxlan: Lookup FIB in either IPv4 or IPv6 families.Jon Loeliger1-4/+5
Prior to this commit, the VXLAN "create" API assumed the vrf_id belonged to only the IPv4 FIB tables space. With this commit, the FIB table is found in either the IPv4 or IPv6 table as determined by the is_ipv6 flag. This follows the same pattern that was already being done in the CLI code for the VXLAN "create" command.

2018-01-31vlib: allocating buffers on thread-x and freeing them on thread-y causesSteven1-2/+1
a crash on debug image (VPP-1151) In debug image, there is extra code to validate the buffer when it is freed. It uses the hash table to lookup the buffer index with spinlock to prevent contention. However, there is one spinlock for each worker thread. So allocating the buffer on thread-x and freeing the same buffer on thread-y causes the validation to fail on thread-y. The fix is to have only one spinlock, stored in vlib_global_main.

2018-01-30VPP-899: Run VPP under SELinuxBilly McFall1-13/+17
Add an SELinux profile such that VPP can run under SELinux on RPM based platforms. The SELinux Policy is currently only implemented for RPM packages, specifically, Fedora, CentOS and RHEL. Doxygen User Documentation has been included (selinux_doc.md). Once some discussion on file locations has completed (see vpp-devlist), updates to the Debug CLI documentation will also need to be updated. Additional changes: Patch Set 2: - Rework selinux_doc.md such that each line is only 80 characters instead of each sentence on a line. Made additonal minor chnages to the text. - Update vHost Debug CLI documentation to reflex new socket location. Cleaned up some text from when I originally wrote it, to better reflex proper use. - Update exec Debug CLI documentation to be more inline with suggested helptext, added text regarding recommended script file location. - For Debian builds, create the /var/log/vpp/ directory. I don't use Debian very much, so please pay extra attention to build-data/platforms.mk and build-root/deb/debian/.gitignore. - Per discussion on VPP call, changed the default log location to /var/log/vpp/vpp.log. - Changed the socket location for vHost in AutoConfig to /var/run/vpp/. Patch Set 3: - Update selinux_doc.md based on comments. Change-Id: I400520dc33f1ca51012d09ef8fe5a7b7b96c631e Signed-off-by: Billy McFall <bmcfall@redhat.com>

2018-01-24Improve tunnel interface creation performanceJohn Lo7-76/+81
Modify interface creation to allow creation of tunnel interfaces without dedicated per tunnel output and tx nodes which are not used for most tunnel types. Also changed interface-output node function vnet_per_buffer_interface_output() so it does not rely on hw_if_index as the next node index which is not flexible nor efficient for large scale tunnel interfaces. The improvenemts are done for VXLAN, VXLAN-GPE, GENEVE and GTPU tunnels. GRE tunnel is still using per tunnel output nodes which will be changed in a separate patch with other GRE enhencements.

2018-01-23For DHCP client configuration control the setting of the broadcast flag in theNeale Ranns5-100/+397
DISCOVER message sent. According to RFC2131: In the case of a client using DHCP for initial configuration (before the client's TCP/IP software has been completely configured), DHCP requires creative use of the client's TCP/IP software and liberal interpretation of RFC 1122. The TCP/IP software SHOULD accept and forward to the IP layer any IP packets delivered to the client's hardware address before the IP address is configured; DHCP servers and BOOTP relay agents may not be able to deliver DHCP messages to clients that cannot accept hardware unicast datagrams before the TCP/IP software is configured. To work around some clients that cannot accept IP unicast datagrams before the TCP/IP software is configured as discussed in the previous paragraph, DHCP uses the 'flags' field [21]. The leftmost bit is defined as the BROADCAST (B) flag. The semantics of this flag are discussed in section 4.1 of this document. The remaining bits of the flags field are reserved for future use. They MUST be set to zero by clients and ignored by servers and relay agents. Figure 2 gives the format of the 'flags' field. this changes means VPP conforms to the: "SHOULD accept and forward to the IP layer any IP packets delivered to the client's hardware address before the IP address is configured" with the caveat that VPP allows DHCP packets destined to the stanard client DHCP port to be delivered. With this enhancement the control-plane is now able to choose the setting of the broadcast flag. Change-Id: Ia4eb2c9bb1e30c29f9192facc645e9533641955a Signed-off-by: Neale Ranns <nranns@cisco.com>

2018-01-16tapv2: deleting tap interface may leak buffers (VPP-1124)Steven4-11/+34
Buffers may be allocated for indirect descriptors by tx thread and they are freed when tx thread is invoked in the next invocation. This is to allow the recipient (kernel) to have a chance to process them. But if the tap interface is deleted, the tx thread may not yet be called to clean up the indirect descriptors' buffers. In that case, we need to remove them without waiting for the tx thread to be called. Failure to do so may cause buffers leak when the tap interface is deleted. For the RX ring, leakage also exists for vring->buffers when the interface is removed.
