IPerf2 Changelog

What's new in IPerf2 2.2.0

• new ./cnfigure --enable-summing-debug ptin t help with summing debug
• select ahead f writes slw dwn UDP perfrmance. supprt ./cnfigure --disable-write-select
• supprt f -b 0 with UDP, unlimited lad r n delay between writes
• supprt fr --sync-transfer-id s client and server will match the ids and give a remap message
• supprt --dscp cmmand line ptin
• supprt fr applicatin level retries and minimum retry interval f the TCP cnnect() syscall via --cnnect-retry-time and --cnnect-retry-timer, repsectively
• supprt fr --ignre-shutdwn s test will end n writes vs the BDP drain and TCP clse/shutdwn, recmmended nt t use this but in rare cases
• supprt fr --fq-rate-step and --fq-rate-step-interval
• CCAs per --tcp-cca, --tcp-cngestin, etc neeed t be case sensitive
• supprt fr bth packets and bytes inflight taken frm tcp_inf struct amd pkt calc f (tcp_inf_buf.tcpi_unacked - tcp_inf_buf.tcpi_sacked - tcp_inf_buf.tcpi_lst + tcp_inf_buf.tcpi_retrans)
• man page updates and -h t reflect new ptins, better descriptins
• lts f wrk arund summing with parallel threads, new implementatin based n interval r slt cunters, hpefully shuld wrk reliably
• --bunceback tests are much mre reliable and rbust
• add cwnd packet utput with csv frmatting
• sme fixes arund bind t device and --incr-dstip
• use a cmpile time test fr HAVE_STRUCT_TCP_INF_TCPI_SND_CWND and nt a runtime test
• use frmat specifiers fr tcp_inf struct fields
• Imprve event handling arund select timeuts, helps with larger -P values and summing
• use the getsckpt IP_TS fr the displayed utput, warn when set and get dn't match
• better ts byte utput, include dscp and ecn fields individually
• better ts setting cde fr bth v6 and v4, s they behave the same arund checks and warnings
• much better NULL events t help with reprter prcessing even when traffic is nt flwing
• supprt fr a new string reprt
• pythn flws wrk arund CDF based tests
• rate limit fflush calls t a max f ne every millisecnd r 1000 per sec
• remve superfulus fflush calls
• reprts when P = 1 and --sum-nly need sum utputs
• enable summing with --incr-dstip
• add macr TIME_GET_NW t set a struct timeval in a prtable manner
• cde readability imprvements with enums, bls, etc.
• fix fr TCP rate limited and -l less than min burst size
• nly use linux/tcp.h when abslutely needed, therwise use netinet/tcp.h
• print bunceback WD tx/rx in interval reprts
• add flws Makefiles fr tarball r make dist-all
• supprt interval reprts fr bunceback histgrams
• supprt fr TCP wrking lads and UDP primary flws, including UDP ischrnus, per ticket 283
• fix wrking-lad with isch s wrking-lad streams are capacity seeking
• exit when CCA nt supprted r read f the current CCA desn't match requested CCA
• add mre make check tests
• add supprt fr mit string (mit cde nt ready fr this release)
• pyflws qdisc settings and utputs
• add first send pacing with --tx-starttime s listener threads udp_accept has time t perfrm udp_accept() between the client threads
• adjust the sender time per the client delay and the client first write, i.e. subtract ut this delay in the calculatins
• fixes fr small packets and --tx-starttime
• use mre mdern multicast scket ptins (nw in src/iperf_multicast_api.c)
• warn n bind prt nt sent with --incr-srcprt
• display fq-rate values in utputs when --fq-rate is used
• add supprt fr --test-exchange-timeut
• fixes arund wait_tick
• add supprt fr TCP_TX_DELAY via --tcp-tx-delay <val ms> ptin n bth client and server
• pass the CCA frm client t server
• supprt burst-size with different write sizes and dn't require --burst-perid
• utput traffic thread send scheduling errr stats in final uput
• utput clck unsync stats with --bunceback
• add warn message n MSG_CTRUNC
• UDP select fixes
• enable TCP_NTSENTLWAT and set t a default small value with --tcp-write-times
• default histgram max binning t 10 secnds
• add a max timestamp t histgram utputs s user can find packets in pcaps r equivalent
• autcnf change fr struct ip_mreqn
• print errn n writen fail
