2020-08-12misc: fix coverity warningsDave Barach11-16/+48
Add an ALWAYS_ASSERT (...) macro, to (a) shut up coverity, and (b) check the indicated condition in production images. As in: p = hash_get(...); ALWAYS_ASSERT(p) /* was ASSERT(p) */ elt = pool_elt_at_index(pool, p[0]); This may not be the best way to handle a specific case, but failure to check return values at all followed by e.g. a pointer dereference isn't ok.

2020-08-12vlib: Skip core 0 if workers are configured.Jon Loeliger1-0/+15
According to the description in the startup.conf, the assignment of worker threads starts with the lcore following the main_lcore. A non-zero skip_cores will correctly achieve this assignment. However, prior to this patch when workers are assigned, the code picks up and assigns core 0 even thought it shouldn't. This patch determins if a non-zero number of workers are desired and if so, marks CPU unavailable for a worker assignment.

2020-08-12ip6: fix l4 checksum with hop-by-hop headerMatthew Smith1-13/+23
L4 checksums for IPv6 should be calculated using a pseudo header that includes the source/destination addresses, payload length, and payload protocol. ip6_tcp_udp_icmp_compute_checksum() was using the payload length and protocol from the IPv6 header. If there is a hop-by-hop header (or any other extension header), the payload length used for the pseudo header should only include the upper layer header and payload and not the extension header bytes. Same deal with the protocol, the upper layer next header value should be used instead of the extension header.

2020-08-12stats: fix state counter removalVladimir Isaev9-98/+178
Avoid using vec_del1() for directory vector to keep indexes valid all the time. There are state counters for each slave in LACP bond mode which can be dynamically created and removed. Vector index is used to access these counters. But also vec_del1() is used to remove counter from vector. This function changes the index of the last element, so after this we are unable to access ex-last element using old index. As a result it is not possible to add-del-add two interfaces to the LACP bond: DBGvpp# create bond mode lacp BondEthernet0 DBGvpp# create packet-generator interface pg1 DBGvpp# create packet-generator interface pg2 DBGvpp# bond add BondEthernet0 pg1 DBGvpp# bond add BondEthernet0 pg2 DBGvpp# bond del pg1 DBGvpp# bond del pg2 DBGvpp# bond add BondEthernet0 pg1 DBGvpp# bond add BondEthernet0 pg2 bond add: /if/lacp/1/3/partner-state is already register Type: fix Signed-off-by: Vladimir Isaev <visaev@netgate.com> Change-Id: I2c86e13905eefdef6233369cd4ab5c1b53d123bd (cherry picked from commit 72e31bc2d9b910147c09e1c329713fccc873a018)

2020-08-12virtio: vhost gso is broken in some topologySteven Luong1-2/+8
Recent modification added a call to vnet_gso_header_offset_parser in the beginning of vhost_user_handle_tx_offload. The former routine may set tcp or udp->checksum to 0. While it is appropriate to set it to 0 for the GSO packet, it is broken and causes checksum error if the aformentiooned routine is called by a non-GSO packet. The fix is to not call vhost_user_handle_tx_offload if the buffer does not indicate checksum offload is needed.

Type: fix Fixes: be2286b0 This patch does following: - If terminating frame has consecutive packets with same source IP, this patch avoids fib lookup for those packets in ip4-local node. This drops cycle count for ip4-local node on both ARM and x86. It being done by enabling dead code in else {} case of ip4_local_check_src_x2() and ip4_local_check_src() functions. - In case all packets in terminating frame have unique source IP (e.g: incrementing), ip4-local is costlier by 2 cycles (broadwell) Change-Id: I472ddc324716cec8bfe601568b8aeb7565f97ab3 Signed-off-by: Nitin Saxena <nsaxena@marvell.com> (cherry picked from commit 2d18d2ea9f0e3d6c47d365ec135af651b14e8165)
