At most a single element of this vector is always used. Once rfs constructor is complete there must be exactly one attach_flow_data element in case of ring_simple. For ring_tap this element remains null. Signed-off-by: Alexander Grissik <[email protected]>

Set ETIMEDOUT errno and return -1 from recv in case a socket was timed out, instead of 0 return value and 0 errno. For instance, in case of TCP keep alive timeout. Signed-off-by: Alexander Grissik <[email protected]>
The idea is to scan all rpm/deb packages for personal emails we should not be releasing packages with such emails the scan is done on both the metadat info and the changelog of a specific package Issue: HPCINFRA-919 Signed-off-by: Daniel Pressler <[email protected]>
reclaim_recv_single_buffer() accumulates buffers in a list. In the performance oriented API we want to reuse hot buffers immediately, so reclaim_recv_buffers() implementation is more suitable. Signed-off-by: Dmytro Podgornyi <[email protected]>
The memory callback provides hugepage size of the underlying pages. Replace hardcoded 0 with real hugepage size. Keep the page size in xlio_allocator object. This field a relevant only the hugepage allocation method and 0 in all other cases. Signed-off-by: Dmytro Podgornyi <[email protected]>
XLIO Socket API must guarantee that the XLIO_SOCKET_EVENT_TERMINATED is not followed by any other events. Therefore, all the TX completion events must be completed by that moment. Do a polling iteration before calling socket destructor to increase the chance that all the relevant WQEs are completed. This mechanism needs to be improved in the future.

xlio_init_ex() changes some default parameters. However, a global object can trigger safe_mce_sys() constructor at the start. Therefore, we need to re-read the environment variables again to guarantee that the changed parameters take place. Signed-off-by: Dmytro Podgornyi <[email protected]>
Avoid using connect() with sock fd interface, because fd_collection doesn't keep xlio_socket_t objects. Signed-off-by: Dmytro Podgornyi <[email protected]>
xlio_socket_t objects aren't connected to the fd_collection anymore. Therefore, all the methods must be called from the sockinfo_tcp objects directly. Also, xlio_socket_fd() is not relevant anymore and can be removed. Signed-off-by: Dmytro Podgornyi <[email protected]>
Iterate over std::list of TCP sockets while erasing socket during iteration. Overcomed by increasing iterator before erase. Signed-off-by: Iftah Levi <[email protected]>
rdma-core limits number of UARs per context to 16 by default. After creating 16 QPs, XLIO receives duplicates of blueflame registers for each subsequent QP. As results, blueflame doorbell method can write WQEs concurrently without serialization and this leads to a data corruption. BlueFlame can make impact on throughput, since copy to the blueflame register is expensive. It can improve latency in some low latency scenarios, however, XLIO targets high traffic/PPS rates. Removing blueflame method also slightly improves performance in some scenarios. BlueFlame can be returned back in the future to improve low-latency scenarios, however, it will need some rework to avoid the data corruption. Signed-off-by: Dmytro Podgornyi <[email protected]>
The inline WQE branch is not likely in most throughput scenarios. Signed-off-by: Dmytro Podgornyi <[email protected]>
Avoid calling register_socket_timer_event when a socket is already registered (TIME-WAIT). Although there is no functionality issue with that, it produces too high rate of posting events for internal-thread. This leads to lock contantion inside internal-thread and degraded performance of HTTP CPS. Signed-off-by: Alexander Grissik <[email protected]>

UTLS uses tcp_tx_express() for non blocking sockets. However, this TX method doesn't support XLIO_RX_POLL_ON_TX_TCP. Additional RX polling improves scenarios such as WEB servers. Insert RX polling into UTLS TX path to resolve performance degradation. Signed-off-by: Dmytro Podgornyi <[email protected]>
In heavy CPS scenarios a socket may go to TIME-WAIT state and be reused before first TCP timer registration is performed by internal-thread. 1. Setting timer_registered=true while posting the event prevents the second attemp to try and post the event again. 2. Adding sanity check in add_new_timer that verifies that the socket is not already in the timer map. Signed-off-by: Alexander Grissik <[email protected]>
Added new env parameter - XLIO_MAX_TSO_SIZE. It allows the user to control maximum size of TSO, instead of taking the maximum cap by HW. The default size is 256KB (maximum by current HW). Values higher than HW capabilities won't be taken into account. Signed-off-by: Iftah Levi <[email protected]>

For incoming sockets - no change. For outgoing sockets - since outgoing sockets occupy a local port, we should release it on the socket destructor to prevent race from another socket to use the same port. This race might cause XLIO to hold 2 sockets with the same RFS object at the same time, and this is fatal (particularly for TCP). Signed-off-by: Iftah Levi <[email protected]>
