Version 6.3.23-0:
Date + Time 2012-12-15
=======================
Added:
- Support for epoll EPOLLOUT ET.
Known limitation: In socket UDP, both the OS and VMA will announce an fd as ready to write for the first time.
- RM #109300: Add enviroment variable VMA_TCP_TIMER_RESOLUTION_MSEC, to allow control of TCP timer rate.
Changed:
- RM #101701:
1. United VMA params: VMA_RX_POLL_OS_RATIO and VMA_RX_SKIP_OS into one
parameter: VMA_RX_UDP_POLL_OS_RATIO
2. VMA_RX_UDP_POLL_OS_RATIO value will determine after how many CQ polls will
OS fd be polled. No matter if hit or miss. No matter if socket is blocking or non-blocking.
Fixed:
- RM #104860: Fixed TCP socket connect hang in case connection has failed
- RM #106790: Fixed VMA_INTERNAL_THREAD_AFFINITY option generates a core dump, when it's set by a hexadecimal value
- RM #95010, #95010 : Fixed TCP retransmition mechanism.
- RM 101701: non blocking iomux should only poll once
- RM #110853: Fixed panic in case of drop_membership without add_membership first
- RM #91299: Fixed OS stats. We counted cases of EAGAIN as os_errors instead of os_eagain
Version 6.3.22-0:
Date + Time 2012-11-30
=======================
Added:
-Enabled fragmentation handling
-Added enviroment variable flag: VMA_SUPPRESS_IGMP_WARNING
Fixed:
-RM #101397: Pure virtual function was called in: return_buffers_to_owners, because mem_buf_desc_owner was freed earlier.
Version 6.3.21-0:
Date + Time 2012-11-29
=======================
Added:
-Enabled Loopback support in IB MC.
-RM #101284: Added warning print in case umcast is enabled
-RM #102181: Added support for MSG_DONTWAIT with TCP socket
-New Sockperf - 2.5.193
Major Changes:
- Bug fix: warmup messages were counted as duplicated/out-of-order messages.
- Bug fix: sockperf flags (-p -m -r) parsing
- Bug fix: negative valid run time of dropped packet
Fixed:
-RM #101405: Fixed libvma.conf bug: Changed the multicast rule check to mc ip address instead of local interface ip address.
The rules shoudl address the packet's dest ip address.
-RM #94993: Prioritizing OS in non-blocking sockets that were mapped in select/poll/epoll.
This will fix the following bug (example scenario):
1. Non-blocking UDP socket binds to INADDR_ANY.
2. Socket is mapped in iomux.
3. Not-offloaded traffic arrives. iomux notifies that fd is ready
4. Because the fd is mapped as offloaded, in rx flow, we check the OS once
each 'rx_poll_os_ratio' times, and sampling it once each 'rx_skip_os' times.
Because it's a non-blocking fd, we'll get EAGAIN although iomux already
notified this fd as ready. (Very problematic when using EPOLLET)
-RM #101397:Removed the code that deals with fragmentation and added a warning printout and drop packet in case of a fragmented packet
Added warning printout with packet info in case of drop due to fragmentation
-RM #102178: Fixed UDP MSG_DONTWAIT flag support in VMA
-RM #102182: Fixed non blocking logic in TCP socket
-RM #101874: Fix to perforomnce bug in select and poll that coused by latest commit that fixes functionality bug

-RM #100485: Added printout for user to correctly use Rx buffs env param in case not enough available Rx buffs for cq allocation
Removed:
-VMA mechanism of connect timeout that was based on measuring time, and rely only on the mechanism of lwip which count SYN retransmissions
-RM#100754: VMA_IGMP support.Not relevant for this version and when disabled, prevents receiving traffic.
Fixed:
-RM #97234, RM #101069: Fixed coverity error in vlogger.h
-RM #94996 (RM BGATE #1217): Avoid binding twice in case of calling connect again after previous call failed.
