uIP v0.7.8.6 (Jun 27, 2019)

=======================================================

    Fixes:

    -------

      1. Problem: OS fails to boot after one path is

                  disconnected from iSCSI MPIO config.

         Change: In the event of DHCP failure, killing of enable_nic_thread did

                 not process any iscsid requests leading to error,

                 iscsistart: Could not broadcast to uIP after 5 tries

                 and login failure of active path.

                 Added fix to not kill enable_nic_thread and allow further

                 processing of iscsid requests and performing login

                 to next active path.

         Impact: All

uIP v0.7.8.5 (Nov 20, 2018)

=======================================================

    Fixes:

    -------

      1. Problem: CQ102578: observing ISCSI initiator IP ping drop

         Change: 1. Do not flush tx queue on each uio interrupt

		 2. Use UIO BD index instead on buffer index.

		 3. Set buf_size in case of ICMP and ARP packet

         Impact: QL41xxx adapters

      2. Problem: CQ103034 - Unable to boot iSCSI BFS in IPv6 DHCP config

         Change: Limit retries of performing dhcpv6 before declaring dhcp failure

         Impact: All

      3. Problem: CQ102438: I/O fails to resume on multipath LUN during port toggle.

         Change: lib/cnic, lib/qedi, Release xmit_mutex in error code path and

                 during clear tx queue.

         Impact: QL84xx adapters

      4. Problem: Netlink buffer corruption when more than one host

		  try to xmit packet at the same time

         Change: Add inter-host mutex while doing xmit

         Impact: All

uIP v0.7.8.4 (Feb 22, 2018)

=======================================================

    Fixes:

    -------

      1. Problem: CQ95605: iSCSI BFS in DHCP config intermittently fails to boot

                  into the OS when source and destination addresses are in

                  different networks.

         Change: Allow ARP for non-matching source and destination addresses.

                 For source and destination IP addresses in different networks,

                 continue with the ARP retries and further login process

                 instead of assuming abrupt failure. iSCSI offload adapters

                 may not rely on netmask information for successful iSCSI

                 target login.

         Impact: All

uIP v0.7.8.3 (May 18, 2017)

=======================================================

    Fixes:

    -------

      1. Problem: CQ93985: iscsiuio seg faults if discovery done to not

                  reachable target

         Change: Serialize xmit_mutex lock to prevent iscsiuio seg fault.

         Impact: All

      2. Problem: CQ91497 - Initiator fails to acquire IPv6 DHCP address

                  from the DHCP server

         Change: Initialize the transaction-id within the dhcpv6 packet with

                 correct byte order, to fix the trans-id mismatch error.

         Impact: All

      3. Problem: Missing qedi ping transport hook

         Change: Add qedi ping transport hook

         Impact: 10/25/40/50GGbE Controller (iSCSI)

uIP v0.7.8.3 (Sept 28, 2016)

=======================================================

   Enhancements

   ------------

   1. Change: Add support for the new qedi transport

      Impact: 10/25/40/50GGbE Controller (iSCSI)

uIP v0.7.8.2 (Dec 10, 2013)

=======================================================

   Fixes

   -----

   1. Problem: Cont00072053 - Some hardware iSCSI paths fail during test

      Cause:   The test exercised a corner case where the ARP cache flush

               mechanism didn't work properly

      Change:  Fixed the ARP cache flush mechanism

      Impact:  All

   Enhancements

   ------------

   1. Change:  Added a new tx doorbell field in the uio path to work with

               the new bnx2x/cnic drivers that supports VF_RSS

      Impact:  10G only

   2. Change:  Fixed the iface.subnet_mask decoding for IPv6

      Impact:  IPv6

uIP v0.7.8.1b (May 01, 2013)

=======================================================

   Enhancements

   ------------

   1. Change:  Performance optimization by caching the page size

      Impact:  All

   2. Change:  Fixed a bug in the tx completion interrupt handler

      Impact:  10G only

uIP v0.7.6.1g (Jan 14, 2013)

=======================================================

   Fixes

   -----

   1. Problem: Cont00067316 - IPv6 address prefix length < 32

               bits fails to connect

      Cause:   CIDR notation has an order bug in the IPv6 section

               whenever the prefix length specified is < 32

      Change:  Fixed the network order bug

      Impact:  IPv6 only

uIP v0.7.6.1f (Nov 14, 2012)

=======================================================

   Fixes

   -----

   1. Problem: Cont00065768 - RHEL5.X iscsiuio segfault possible

               if there is a specific 1024 byte size broadcast

               packet

      Cause:   This is another corner case where the packet size

               is also exactly 1024 bytes + padding that exceeded

               the DMA rx buffer.  The previous fix was not

               sufficient

      Change:  Ensure that the packet size + padding do not

               exceed this limit.

      Impact:  10G only.  1G already has the guard against it.

uIP v0.7.6.1e (Nov 07, 2012)

=======================================================

   Fixes

   -----

   1. Problem: Cont00066397 - Unable to connect to iSCSI target

               with NPAR enabled on 57840

      Cause:   The PCI device ID for 57840_MF has been changed from

               0x16ab to 0x16a4

      Change:  Updated the PCI id table to match exactly what the

               bnx2x 1.76 indicates

      Impact:  57840 MF

uIP v0.7.6.1d (Oct 31, 2012)

      Impact:  10G 57840

uIP v0.7.6.1b (Oct 09, 2012)

=======================================================

   Fixes

   -----

   1. Problem: Cont00065690 - Vconfig method of connecting over

               tagged vlan with IPv6 failed

      Cause:   The new net param support changes has prevented

               the old vconfig method from execising the IPv6

               acquisition engine properly

      Change:  Ensure that this old vconfig method to run the IPv6

               acquisition engine properly and to its entirety

      Impact:  IPv6 + VLAN using the network VLAN configuration

               method

   2. Problem: Cont00065768 - RHEL5.X iscsiuio segfault possible

               if there is a specific 1024 byte size broadcast

               packet

      Cause:   This is a corner case where the packet size is

               exactly 1024 bytes + padding that exceeded the

               DMA rx buffer.  This has been there since day 1.

      Change:  Ensure that the packet size + padding do not

               exceed this limit.

      Impact:  10G only.  1G already has the guard against it.

   Enhancements

   ------------

   1. Change:  Source optimization - backported source code fixes

               as reported from the upstream submission patch

      Impact:  ALL

   ------------

   1. Change:  Enable HP SD mode

      Impact:  577XX/578XX

uIP v0.7.4.2j (Jul 18, 2012)

=======================================================

   Fixes

   -----

   1. Problem: Cont00064665 - Linux iSCSI connects via gateway address

               on the wrong subnet

      Cause:   The gateway address used was not checked against the

               subnet mask specified before the ARP requests.  Since

               this behavior deters from how L2 operates, therefore,

               a change was made to correct this.

      Change:  Added check of the gateway specified against the subnet

               specified.

      Impact:  Static IPv4 operation

   2. Problem: Cont00064722 - Linux iSCSI unable to force IPv6 LL

               override (advanced iface parameters)

      Cause:   The override LL address was not being populated to the

               IPv6 address database correctly

      Change:  Added this correctly to the IPv6 initialization

      Impact:  Static/DHCP IPv6 LL address override only

uIP v0.7.4.2i (Jul 11, 2012)

=======================================================

   Fixes

   -----

   1. Problem: Cont00064604 - Fails to connect to routed IPv6 target

               via RA

      Cause:   The default router IPv6 address was not being retrieved

               correctly.

      Change:  Fixed the default router IPv6 address read

      Impact:  All

uIP v0.7.4.2h (Jun 15, 2012)

=======================================================

   Fixes

   -----

   1. Problem: Cont00063863 - can't boot into offload image

               when VLAN is enabled

      Cause:   During the iSCSI login exchange, certain iSCSI targets

               will send an ARP request even though the TCP connection

               has been made.  The bug was in this ARP reply where

               the local MAC was corrupted when VLAN is enabled.

      Change:  Fixed the ARP reply packet

      Impact:  All

uIP v0.7.4.2g (Jun 08, 2012)

=======================================================

   Fixes

   -----

   1. Problem: Cont00063816 - The initiator is not able to connect

               to the iSCSI targets over VLAN

      Cause:   The process packet routine did not consider the PCP

               of the VLAN tag to be non-zero.  This created a

               mismatch when this VLAN tag was compared against the

               nic_iface->vlan_id which doesn't include the PCP.

      Change:  Added the consideration of non-zero PCP

      Impact:  All

uIP v0.7.4.2f (Jun 04, 2012)

=======================================================

   Fixes

   -----

   1. Problem: Cont00063626 - Static IPv6 does not connect when

               the prefix len is not set explicitly

      Cause:   The IPv6 prefix length was not set correctly

               for Static IPv6 operation when CIDR notation is

               not specified

      Change:  Fixed the default prefix length

      Impact:  Static IPv6

   2. Problem: Cont00063651 - Cannot connect to iSCSI targets

               HP PTM/SF

      Cause:   Switch-Dependent mode + invalid Outer VLAN was

               not supported

      Change:  Allow SD+invalid OV to fallback to SF operation mode

      Impact:  5771X/578XX

uIP v0.7.4.2e (May 30, 2012)

=======================================================

   Fixes

   -----

   1. Problem: Cont00063443 - Compilation error on SLES11sp1

      Cause:   The iface_num field was not defined

      Change:  Fixed all references to iface_num

      Impact:  SLES11sp1

   2. Problem: Cont00063518 - HBA fails to connect across router

               using iface.gateway address

      Cause:   The gateway override code did not populate the

               address into the lower level engine

      Change:  Fixed the gateway override code

      Impact:  IPv4 Static IP operation

   3. Problem: Cont00063567 - IPv6 LL and RA override does not work

      Cause:   The IPv6 LL/RA override addresses were overwritten

               by the NDP engine

      Change:  Fixed the LL/RA override code

      Impact:  IPv6 operation

   Enhancements

   ------------

   1. Added support for jumbo MTU (independent from the L2 MTU)

uIP v0.7.4.2d (May 21, 2012)

=======================================================

   Fixes

   -----

   1. Problem: Cont00063421 - Static IPv6 cannot connect via RA/LL

      Cause:   The router advertise and the linklocal address

               were corrupted due to the override capabilities

               added for the newer open-iscsi util

      Change:  Fixed the address override code

      Impact:  Static IPv6

   Enhancements

   ------------

   1. Allow VLAN tag = 1 (router management) to connect offload

uIP v0.7.4.2c (May 09, 2012)

=======================================================

   Fixes

   -----

   1. Problem: RHEL BZ 734010/804580 - issues found by the Coverity

               scan

      Cause:   10 code issues were flagged for revision

      Change:  Fixed all area of concern

      Impact:  All

   2. Problem: Cont00063177 - IPv4 DHCP with VLAN specification in

               iface file gets wrong address

      Cause:   The DHCPv4 handler was not discriminating the VLAN tag

               associated with the DHCP offers from multiple DHCP

               servers

      Change:  Changed the DHCPv4 handler to drop DHCP offer packets

               that doesn't match the VLAN tag of the intended DHCP

               discovery packet

      Impact:  DHCPv4 operation

uIP v0.7.4.2b (May 01, 2012)

=======================================================

   Fixes

   -----

   1. Problem: Cont00062993 - IPv6 DHCP with VLAN specification in

               iface file gets wrong address

      Cause:   The DHCPv6 request was using the same DUID as always

               so the non-VLAN DHCP server responded to our broadcast

               instead

      Change:  Changed the DHCPv6 request DUID to link address + time

               instead of link address alone

      Impact:  DHCPv6 operation

uIP v0.7.4.1j (Apr 24, 2012)

=======================================================

   Fixes

   -----

   1. Problem: Cont00062805 - Cannot login to iSCSI targets on RHEL6.3

      Cause:   The problem was caused by a change made to the iface_rec

               structure in the RHEL6.3 inbox open-iscsi util

      Change:  The new changes is now incorporated

      Impact:  All

=======================================================

   Fixes

   -----

   1. Problem: Cont00062660 - Unable to login with VLAN iscsiuio

               on RHEL6.2

      Cause:   The open-iscsi util in RHEL6.2 has a bug which

               does not pass the correct iface_num to iscsiuio

      Change:  Added workaround to fall back to do the legacy

               VLAN support if iface_num and vlan_id = 0

      Impact:  RHEL6.2

uIP v0.7.4.1h (Apr 13, 2012)

=======================================================

   Enhancements

   ------------

   1. Added support for the new iface_num field in the iscsi_uevent

      path

   2. Fixed bug in the nic_iface search engine based on iface_num

uIP v0.7.4.1g (Mar 22, 2012)

=======================================================

   Fixes

   -----

   1. Problem: Cont00061869 - Unable to setup an offload iSCSI

               connection with FLR/NPAR under ESX5.0:PDA

      Cause:   The physical function ID was previously extracted

               from the sysfs of the VM which might not be consistent

               to the actual physical setup due to the function

               remapping in the hypervisor

      Change:  Read the physical function ID directly from the BAR0

               ME register

      Impact:  All

   2. Problem: Cont00062170 - IPv6 login/logout stress fails

      Cause:   The packet interrupt was lost after running the test

               for a much longer period of time.  A bug in the

               packet processing routine was found to exit prematurely

      Change:  Fixed the packet processing routine to process all

               packets before exiting

      Impact:  All

uIP v0.7.4.1f (Mar 19, 2012)

=======================================================

   Fixes

   -----

   1. Problem: Cont00062170 - IPv6 login/logout stress fails

      Cause:   The packet buffer routine for IPv6 did not take

               network order <-> host order into consideration

      Change:  Added a htons call to compensate for the ntohs pair

      Impact:  All

uIP v0.7.4.1e (Mar 08, 2012)

=======================================================

   Fixes

   -----

   1. Problem: Cont00061978 - Load/unload stress test fails

      Cause:   The bnx2x open request was failing due to the module

               request procedure.  However, the open failure was

               not being handled correctly.

      Change:  Fixed the device open error handling

      Impact:  5771X/578XX

uIP v0.7.4.1d (Mar 02, 2012)

=======================================================

   Fixes

   -----

   1. Problem: Cont00061708 - Unable to log into target after running

               driver load/unload

      Cause:   A bug was introduced in the previous bug fix (CQ61459)

               where a pthread_cond_broadcast call was erroneously

               enabled

      Change:  Restored this back

      Impact:  All

uIP v0.7.4.1c (Feb 16, 2012)

=======================================================

   Fixes

   -----

   1. Problem: Cont00061529 - Unable to connect to target after an

               initial failed login attempt until iscsi service is

               restarted

      Cause:   Upon a failed DHCPv4 acquisition due to the wrong VLAN

               tag in the initial iface setup, any iscsid connect request

               from the same NIC will get dropped due to a bug.

      Change:  Fixed the bug which prevented new iscsid connect requests

               from getting honored

      Impact:  All

   Enhancements

   ------------

   1. Updated README

   Fixes

   -----

   1. Problem: Cont00061513 - Unable to connect to target over VLAN

               interface

      Cause:   The VLAN id was not properly passed back to the CNIC

               driver for the offload request

      Change:  Fixed the VLAN id being passed back to the CNIC driver

      Impact:  All

uIP v0.7.4.1a (Feb 01, 2012)

=======================================================

   Fixes

   -----

   1. Problem: Cont00049383 - No mechanism in iface file to support

               gateway/routing

      Change:  Added support for the additional network parameters

               as passed from the newer iscsi-util.

               These parameters include:

               IPv4: subnet_mask, gateway

               IPv6: ipv6_linklocal, ipv6_router,

                     ipv6_autocfg, linklocal_autocfg, router_autocfg

               VLAN: vlan_id, vlan_priority, vlan_state

               Other: mtu, port

      Impact:  All

   2. Problem: Cont00060806 - Unable to connect target using DHCP over

               tagged VLAN

      Change:  DHCP+VLAN is a new feature enhancement that was added

               alongside all other new iface parameters.

      Impact:  All

   1. Problem: Cont00060734 - ifupdown-mtu change stress with active

               session causes iscsiuio to fail

      Change:  Fixed a race condition between the nic enable thread

               and when DHCP fails

      Impact:  All

uIP v0.7.2.1d (Dec 28, 2011)

=======================================================

   Fixes

   -----

   1. Problem: Cont00060368 - segfault observed after failing both

               mpio paths

      Change:  Various memory leaks were identified and resolved in

               the nic cleanup path

      Impact:  All

uIP v0.7.2.1c (Dec 16, 2011)

=======================================================

   Enhancements

   ------------

   1. Change:  Disable HP SD mode

uIP v0.7.2.1b (Dec 14, 2011)

=======================================================

   Enhancements

   ------------

   1. Change:  Default iscsiuio logging to off.  Use the '-d'

               option to enable

uIP v0.7.0.14g (Oct 25, 2011)

=======================================================

   Enhancements

   ------------

   1. Change:  Fixed the compilation under RHEL6.2

   2. Change:  Added oom_adjust call to prevent OOM Killer from killing

               iscsiuio when memory is low

   3. Change:  Added mlockall setting to prevent page swap

uIP v0.7.0.14f (Oct 20, 2011)

=======================================================

   Fixes

   -----

   1. Problem: Cont00058994 - DOS vulnerability in uip during UDP flood

      Cause:   The warning messages from the UDP handler was logging

               at a rate faster than the log file logrotate rate

               Therefore, the system's OOM eventually got kicked in to

               start terminating running processes which includes iscsiuio

      Change:  Moved several UDP warning messages from the default log

               level to the debug log level

      Impact:  All (minor)

   2. Problem: Cont00059288 - Show segfault w/ SLES11 SP1 Xen kernel

      Cause:   The bnx2x chip_id was not read correctly from the PCIe BAR1

               under the Xen kernel.  The error was in the mmap area.

      Change:  Corrected the mmapping of the PCI MMIO space.

      Impact:  Xen kernels

   Enhancements

   ------------

   1. Change:  Changed the log file open error to a warning and let

               the daemon progress.  This was only observed under iSCSI boot

uIP v0.7.0.14e (Sep 19, 2011)

=======================================================

   Fixes

   -----

   1. Problem: Cont00058678 - Can not iboot target from ipv6 path

               using VLAN

      Cause:   A bug was found in the path request path where the vlan

               iface's protocol family was not used correctly in the

               iface search

      Change:  This has been corrected

uIP v0.7.0.14d (Sep 16, 2011)

=======================================================

   Fixes

   -----

   1. Problem: Cont00058602 - Can't iboot using IPv6 offload path

      Cause:   The bug was exposed by a fix in 0.7.0.14c where the

               IPv6 router solicitation timeout exceeded the nic

               enable thread timeout.

      Change:  The IPv6 router solicitation timeout has been adjusted

uIP v0.7.0.14c (Sep 01, 2011)

=======================================================

   Fixes

   -----

   1. Problem: Cont00058256 - Sessions fail after loginstress to via

               simultaneous ipv4 and ipv6 dhcp

      Cause:   Switching between DHCPv4/v6 coupled with VLAN exposed

               a drawback in our nic_iface architecture design where

               VLAN is not specified by iscsid.

      Change:  The code was optimized and improved the performance when

               switching between DHCPv4/v6+VLAN.  However, the ultimate

               fix is to make use of the net config parameters introduced

               in the newer open-iscsi util which will identify the

               specific VLAN nic_iface to use.

   Enhancements

   ------------

   1. Change:  Added support for bnx2x-1.71.00

uIP v0.7.0.14b (Aug 23, 2011)

=======================================================

   Fixes

   -----

   1. Problem: Cont00057840 - RHEL6.2 inbox: Unable to connect to

               targets with 5709

      Cause:   For cases when the bnx2/bnx2x driver gets removed, the

               uio database that was built by cnic would have the device

               ->net reference removed.  This has caused an unnecessary

               timeout of 5s for each stale uio entry in the database.

      Change:  Adjusted the routine which seeks the device->net entry

               to include more logic instead of hard waiting for 5s.

   Enhancements

   ------------

   1. Change:  Added support for RHEL6.2 for out-of-box release

   2. Change:  Updated the man page with -h and -p info

   3. Change:  Updated the -h info

uIP v0.7.0.13 (Aug 10, 2011)

=======================================================

   Fixes

   -----

   1. Problem: Cont00057768 - iscsiuio logrotate causes daemon failure

      Cause:   The logrotate script will send a SIGUSR1 signal to notify

               the iscsiuio daemon of such action.  However, the daemon

               wasn't programmed to catch this signal.

      Change:  Restored the catching of this signal

uIP v0.7.0.12 (Aug 04, 2011)

=======================================================

   Fixes

   -----

   1. Problem: Cont00050634 - brcm_iscsiuio Tainted: running IoZone,

               Iometer and receiving a UDP flood on 3260

      Cause:   Upon iscsiuio termination, because of the UDP flood,

               the nic thread will be busy servicing those UDP packets

               while the signal handling thread will free up all nic

               resources.  The two threads were not in sync.

      Change:  Added a nic_remove_all routine to destroy all nic threads

               before the nic resources get freed.

   Enhancements

   ------------

   1. Change:  Fixed all warnings as reported by RHELS' Coverity testing.

uIP v0.7.0.11 (Aug 02, 2011)

=======================================================

   Fixes

   -----

   1. Problem: Erroneous VLAN tag was being passed by iscsid for connect

               request

      Cause:   The iscsid's iface_rec_t ipc message does not contain this

               vlan field.  This field was added in uIP for future vlan

               support.  Since the buffer allocated to receive such message

               in uIP didn't get initialized, therefore, garbled up VLAN

               tag was getting used.

      Change:  Added the initialization of this buffer.

uIP v0.7.0.10 (Jul 26, 2011)

=======================================================

   Fixes

   -----

   1. Problem: Can't offload when switching from Static to DHCP then back to

               Static IPv4 when connecting through a VLAN interface

      Cause:   The VLAN processing code did not reinstall the IP address

               from the default nic_iface to the associated VLAN nic_iface.

               This was only done on the very first time when the VLAN

               interface was created and not on subsequent instances.

      Change:  Added code to mirror the default nic_iface IP/netmask/ip_config

               on the VLAN nic_iface on every new connection request.

uIP v0.7.0.9 (Jul 19, 2011)

=======================================================

   Fixes

   -----

   1. Problem: Can't offload to 57810 NPAR NIC

      Cause:   The MF/VF variant of the PCI IDs were not supported previously

      Change:  Added support for the MF/VF variants for 57800/57810/57840

uIP v0.7.0.8 (Jun 30, 2011)

=======================================================

   Fixes

   -----

   1. Problem: Cont00056522 - Unable to connect to iSCSI target using

               netxtreme2 package 7.0.9

      Cause:   The iSCSI L2 ring's CID has changed from 17 to 49

      Change:  The code now gets L2 iSCSI ring CID from the l2_buf directly.

               This will work with any version of the cnic driver because

               the location is a zero before this change.

uIP v0.7.0.7 (Jun 23, 2011)

=======================================================

   Fixes

   -----

   1. Problem: Cont00056460 - iSCSI Offload boot RHEL5u5 x64 dropped tagged

               packets with iSCSI Offload Boot with untagged

      Cause:   The ICMP echo replies to the target was corrupted in both

               1g and 10g mode

      Change:  The code will now handle both VLAN stripped and no VLAN stripped

               incoming packets correctly.  Also modified the transmit routine

               to strip out any inline VLAN tag before setting up the hw to

               insert VLAN tag.

uIP v0.7.0.6 (Jun 21, 2011)

=======================================================

   Fixes

   -----

   1. Problem: Cont00056231 - DHCPv4 not working with iSCSI HBA w/

               linux-nx2 v7.0.7

      Cause:   The 10g L2 FW HSI has been modified for PCIe performance

               enhancement in the 7.0.7 package (FW 1.70.20) which uIP

               has not adapted to.

      Change:  The eth_rx_cqe size has been increased from 32B to 64B.

   Enhancements

   ------------

   1. Change:  The utility name has changed from brcm_iscsiuio to iscsiuio

               as preparation for upstream submission.

   2. Change:  Updated README

uIP v0.7.0.5 (Jun 02, 2011)

=======================================================

   Fixes

   -----

   1. Problem: Cont00055915 - iSCSI does not connect on 57800 in 4-port mode

      Cause:   The 4-port mode was not being determined correctly

      Change:  Fixed the PORT4MODE register offset and the QZONE_ID macros

uIP v0.7.0.4 (May 24, 2011)

=======================================================

   Fixes

   -----

   1. Problem: Cont00055832 - linux iscsiboot can not login to target using

               offload path (57800)

      Cause:   The device ID comparison routine did not take care of the case

               when one device ID is bitwise superset of another.

      Change:  Fixed the device ID comparison routine.

uIP v0.7.0.3 (May. 19, 2011)

=======================================================

   Enhancements

   ------------

   1. Change:  Updated all fixes to match the released uIP 0.6.4.17

   2. Change:  Modified source and Copyright info as preparation for upstream

               submission

uIP v0.7.0.2 (May. 03, 2011)

=======================================================

   Fixes

   -----

   1. Problem: Cont00048972 - brcm-iscsi.log has no max size and would grow

               to consume all free space on hard disk

      Cause:   There was no mechanism to rotate the log

      Change:  Added logrotate entry and SIGUSR1 signal handling for log rotate

               action

   2. Problem: Cont00054996 - Multi-session, multi-protocol mtu stress

               does not recover all sessions

      Cause:   A segfault was observed during the load/unload module.  The

               problem was caused by an illegal dereference of a pointer

               when IPv6 couldn't find the longest match address from

               the ARP (Neighbor) table.

      Change:  Fixed the dereferencing error

   3. Problem: Cont00054900 - Linux uIP - Please add ability to connect

               to routed target with static iface IPv6

      Cause:   Static IPv6 never runs the IPv6 NDP router sol/adv engine.

      Change:  IPv6 NDP router sol/adv has now been added to static IPv6

               operation.

   4. Problem: Cont00054996 - Multi-session, multi-protocol mtu stress

               does not recover all sessions

      Cause:   Segfaults were observed caused by the accessing of the IPv6

               NDP structure while the nic is undergoing a reset either

               due to a DHCPv4 request from iscsid or the handling of

               if_down due to the NL handler from CNIC.

      Change:  The fix involves the following:

               - Fixed the handling of staggered IPv4/v6 DHCP/static requests

               - Fixed memory leak due to reallocation of IPv4 and IPv6

                 DHCP structs

               - Fixed the pthread join stuck problem in the handling

                 of the if_down NL message

   5. Problem: Cont00054810 - Linux NMI - bnx2x_init_hw_common:PXP2 CFG

               failed running iSCSI MTU stress test

      Cause:   This only happens in DHCPv4 mode.  The problem was caused

               by contention between the elongated window of performing

               DHCP in the enable_nic thread while receiving the asynchronous

               if_down NL message (from the MTU change event) from the

               CNIC NL thread.  The problem occurs when the enable_nic

               thread tries to call bnx2x_open while the other thread

               calls the bnx2x_close routine.

      Change:  Fixed mutex lock bugs for the enable_nic thread.  Also

               extended the nic_disable timeout to 10s to compensate for

               the DHCP operation.

   6. Problem: Cont00054818 - RH6.0 - Unable to logout of iSCSI session

               after running PQA baseline scripts

      Cause:   This was caused by the call to cancel the enable_nic

               thread when disabling the nic but failed to unlock the

               nic mutex that the enable_nic thread held.

      Change:  Wake up the enable_nic thread and wait for it to complete

               instead of canceling it in the nic_disable path.

   7. Problem: Cont00054725 - Previous static HBA IP will be used after

               a new static HBA IP has been created

      Cause:   There was an assumption in the code where if the same

               nic_iface structure was found based on the nic/vlan pair,

               the specified IP address would not be used.  Instead, it

               will continue to use the previous defined IP address.

      Change:  The previous IP address will now be compared against the

               the specified IP address before finishing the parce

               iface request from iscsid.  If different, the current
