* docs: fix up described behavior for iface binding and discoveryMike Christie2009-05-211-6/+10
| | | | | The README said that we auto bind all ifaces in /etc/iscsi/ifaces but we only autobind ones with the transport name tcp.
* iscsi class: force retry when session transitioningMike Christie2009-05-211-1/+1
| | | | | If the session is down we want to force a retry. DID_TRANSPORT_DISRUPTED is limited to 5, so use DID_IMM_RETRY.
* README: add info for how to setup ifaces for cxgb3i and bnx2iMike Christie2009-05-201-17/+150
| | | | | Add some info using cxgb3i and cxgb3i to the README and also add some info on the host mode.
* iscsi sysfs: fix compilation warning about unsigned long long castMike Christie2009-05-203-10/+9
| | | | | uint64_t can be unsigned long long or unsigned long depending on the arch. This just has us use sscanf with PRIu64 to read in our uint64_t.
* iscsid: add cxgb3i filesMike Christie2009-05-202-0/+32
| | | | Forgot to add files with cxgb3i helpers.
* iscsid: add per transport init callbackMike Christie2009-05-204-1/+7
| | | | | | cxgb3i can only support 15360 or smaller. This patch adds a callback to the transport so that drivers can override the default settings or do any other setup they may need to do before we try to login.
* iscsid: disable bind by ipaddress support for iscsi_tcpMike Christie2009-05-201-5/+20
| | | | | | | | | | | We have bind by ip address in io.c, but it was never enabled because the iface code did not read it in for iscsi_tcp. Now with offload using the ipaddress field to set the addr of the port, if the user forgets to the set the transport type to bnx2i or cxgb3i we will end up in the io.c code trying to bind to session using bind() which is going to end horribly. This has us warn the user and fail the connect.
* iscsid: fix unknown kernel event handlingMike Christie2009-05-181-1/+5
| | | | | If we do not recognize the kernel event we should not read in or begin process to the data payload.
* kernel: update 2.6.14 - .23 supportMike Christie2009-05-142-25/+1117
| | | | | | | Update 2.6.14 - .23 support. Note: 2.6.16 and below is still broken. Please email the open-iscsi list if you need this.
* kernel: update 2.6.24 - .25 supportMike Christie2009-05-141-87/+77
| | | | Update 2.6.24 - .25 compat patch.
* kernel: update 2.6.26 supportMike Christie2009-05-141-14/+14
| | | | Update 2.6.26 compat patch.
* kernel: update 2.6.27 supportMike Christie2009-05-142-7/+9
| | | | | | | This updates the 2.6.27 kernel patch and it removes the TARGET_BUSY and starget->can_queue use, because if bugs in 2.6.27 - 2.6.30 (patches sent to fix this for 2.6.30 but not yet merged).
* Sync to upstream 2.6.31 feature window postingMike Christie2009-05-147-461/+581
| | | | | | | | | | | | | | | This syncs the kernel modules to the upstream commit: commit 3c0a012b4f02412bc00b4b71b14d273ef579a44e Author: Mike Christie <michaelc@cs.wisc.edu> Date: Mon May 11 14:07:49 2009 -0400 libiscsi: add debug printks for iscsi command completion path This patch just adds some debug statements for the abort and completion paths. which was sent for the 2.6.31 feature window.
* iscsid: fix bound ep connect event numberMike Christie2009-05-131-3/+2
| | | | | | Fix bad merge. The bound ep connect event number should be 19. When transferring patches from the offload tree to head this got set to the wrong value.
* iscsiadm: use node print helpers in discovery printing codeMike Christie2009-05-101-118/+71
| | | | | This has idbm_print_discovered use the idbm_print_node_and_iface_tree and idbm_print_node_flat helpers.
* iscsiadm: create default iface for all offload cardsMike Christie2009-05-101-23/+24
| | | | | | | | This creates a default iface for all offload cards. The name will be "transport_name.hwaddress". The user just has to then set the ip address by doing iscsiadm -m iface -I transport_name.hwaddress -o update -n iface.ipaddress -v A.B.C.D
* iscsiadm: add host modeMike Christie2009-05-109-28/+308
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This prints out the info for iSCSI hosts in the system.

* iscsiadm: fix iface mode printoutMike Christie2009-05-104-86/+44
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | iscsiadm was printing the iface's sessions, but to be consistent with the node mode, we want to print out the records using the iface. iscsiadm -m iface -P 1 Iface: default Target: iqn.2001-04.com.home:meanminna Portal: 20.15.0.9:3260,1 Portal: 10.10.15.10:3260,1 Iface: iser Iface: cxgb3i.def Iface: cxgb3i Target: iqn.2001-04.com.home:meanminna Portal: 10.10.15.10:3260,1 iscsiadm -m node -P 1 Target: iqn.2001-04.com.home:meanminna Portal: 20.15.0.9:3260,1 Iface Name: default Portal: 10.10.15.10:3260,1 Iface Name: cxgb3i Iface Name: default To get the list of sessions running through a host, we want to add a host mode. This would work like the session mode, but at the host level.
* iscsiadm: fix iscsiadm output when value is not setMike Christie2009-05-103-17/+4
| | | | | If a value is not set we are returning either defaut or unknown or <empty>. This unifies us to use <empty>.
* bind offloaded connection to portMike Christie2009-05-104-3/+17
| | | | | | | | | | | | | | | | | | | | | | | | | | | If we are using a offload card, then iface_set_param will match the iface info to a scsi_host and pass that info down to setup the net settings of the port (currently we just set the ip address). When we create the tcp/ip connection by calling ep_connect, we currently just go by the routing table info. I think there are two problems with this. 1. Some drivers do not have access to a routing table. Some drivers like qla4xxx do not even know about other ports. 2. If you have two initiator ports on the same subnet, the user may have set things up so that session1 was supposed to be run through port1. and session2 was supposed to be run through port2. It looks like we could end with both sessions going through one of the ports. Also how do you edit the routing table for the offload cards? You cannot use normal net tools like route can you? 3. If we set up hostA in the iface_set_param step, but then the routing info leads us to hostB, we are stuck. I did the attached patches to fix this. Basically we just pass down the scsi host we want to go through.
* iscsid: remove unused sysfs_fileMike Christie2009-05-011-2/+0
| | | | sysfs_file is never used.
* iscsi tools: fix event loop compile warningMike Christie2009-05-011-0/+2
| | | | Adding missing forward declaration.
* iscsi boot: fix fw param conn print outMike Christie2009-05-011-2/+2
| | | | | iscsidm -m fw was printing out the %d for the conn params instead of the cid.
* iscsi boot: check for nic/tgt array limitsMike Christie2009-05-011-9/+17
| | | | | | If we were to find more thatn IBFT_MAX targets we would overrun the tgt or nic arrary. This just has us spit an error and return.
* iscsi boot: fix up global counter useMike Christie2009-05-011-4/+9
| | | | | | If the ibft functions are called multiple times tgt_cnt and nic_cnt will continue to increment, so they need to be cleared each time.
* iscsi boot: fix nic ip-addr checkMike Christie2009-05-011-4/+2
| | | | | | | From Hans De Goede: ip-addr will not exist when using dhcp, so raising an error when it does not exist is wrong.
* iscsiadm: fix ppc boot codeMike Christie2009-04-301-6/+4
| | | | | | | Multiple fixes to ppc boot code from Hans de Goede: - nic and dev count need to be cleared. When called multiple times from the lib, they would overrun the nic/initiator arrays. - Have fwparam_ppc not set global dev_count when calling find_file.
* iscsiadm: fix discovery login commandMike Christie2009-04-302-0/+7
| | | | | | | | | | | | If you were to run iscsiadm -m discovery -ip -l to try and login to a targets found during discovery using the /etc/iscsi/send_targets/ip settings, and if CHAP was used then the discovery session login would fail. The reason for this is because we were using the password_len fields to specify the password length to try and allow for any chars. This patch adds those idbm fields back.
* iscsid: set queue depthMike Christie2009-04-124-5/+30
| | | | This sets node.session.queue_depth for the session's devices.
* iscsistart/fw fixesMike Christie2009-04-1210-64/+90
| | | | | | | | | | | | | | - fix double close in fwparam ppc - fix ofdevs and devtree leaks - fix fwparam filename init - fix fwparam ibgt null free - fix iscsistart fw boot and info (sysfs init was not yet called) - fix iscsistart startup iscsid login thread may not be started when iscsistart sends login request. Patch 5b9b71007e43e0c930872b3cadd5c7434a54539d had removed the wait when ECONNREFUSED is returned, which added the regression. TODO: Should add a wait/wakeup for this instead of simple loop and sleep.
* iscsi kernel compat: fix compat patches when debug is onMike Christie2009-03-173-3/+3
| | | | | | | | | | | From Dotan Barak: Add missing ';' in backport patches. When enabling debug in compilation, the lack of semicolon caused a compilation failures on older kernels. Signed-off-by: Dotan Barak <dotanba@gmail.com>
* iscsi conf: increase default MaxRecvDataSegmentLengthMike Christie2009-03-142-4/+3
| | | | | | | | Increase default node.conn[0].iscsi.MaxRecvDataSegmentLength to 262144 to closer match IO sizes we see from block layer. The default block layer max is actually 512K, but in testing setting the MaxRecvDataSegmentLength to this high a value caused perf regressions with some targets.
* iscsid: increase kernel thread niceMike Christie2009-03-147-2/+117
| | | | | | | This sets the default xmit thread nice to -20. This will increase throughput and decrease latency, but could hog the cpu more. In the latter case you can set the nice in /etc/iscsi/iscsid.conf's node.session.xmit_thread_priority setting.
* docs: more README fixesMike Christie2009-02-261-12/+12
| | | | Run spell checker over README.
* docs: fix up type in READMEMike Christie2009-02-251-1/+1
| | | | Fix up spelling of interface in README found by Ulrich.
* iscsid: mv sysfs cache cleanupMike Christie2009-02-221-5/+5
| | | | | | mv sysfs cache cleanup so it runs after the actor test, because software iscsi could run for a while without ever firing a kernel or mgmt event, but the sysfs layout could still change.
* doc: remove wiki referenceMike Christie2009-02-221-4/+1
| | | | | The wiki is down and probably dead for good. This removes a bad link to it.
* docs: update readme with libiscsi_tcp infoMike Christie2009-02-221-3/+3
| | | | | There is a new module, libiscsi_tcp, that is installed. This updates the README.
* iscsid: mv event loop code to new fileMike Christie2009-02-228-99/+163
| | | | | | | The event code does not belong in the mgmt ipc code, because the event code now handles mgmt ipc, requests, actor events, isns events, kernel ipc events. This moves the code to a new file.
* iscsid: flush sysfs cache.Mike Christie2009-02-222-2/+8
| | | | | | After handling an event we should flush the sysfs cache because the device links could change or the attr values could change due to handling the event.
* iscsi tools: update version in preparation for new releaseMike Christie2009-02-211-1/+1
| | | | Update version to 871.
* docs: fix up iscsiadm man page iface infoMike Christie2009-02-211-1/+2
| | | | | | When the offload iface settings changed the doc page got misedited. This should fix it and add some info on what the hw address is.
* iscsid: Fix up connection failed messagesMike Christie2009-02-071-3/+9
| | | | | The connection failed message did not say which connection failed. This has it print out the portal and a strerror value.
* iscsi tool make: add notification that iscsi start was madeMike Christie2009-02-071-0/+1
| | | | When doing a make notify user that iscsistart was built.
* iscsi tools: convert from strncpy to strlcpyMike Christie2009-02-0713-72/+81
| | | | This has us use a safer strlcpy instead of strncpy when we can.
* iscsi tools: convert from strncat to strlcatMike Christie2009-02-079-22/+41
| | | | | We messed up strncat in so many different ways that strlat could fix. This patch converts the userspace uses of strncat to strlcat.
* open-iscsi: Makefile: separate out user: and kernel: make targetsBoaz Harrosh2009-02-071-11/+14
| | | | | | | | Separate out the build of "kernel:" and "user:" targets. [Mike please revisit the @echo output if we need anything added] Signed-off-by: Boaz Harrosh <bharrosh@panasas.com>
* iscsi mod: 2.6.14-19 compatMike Christie2009-02-071-17/+18
| | | | Fix compat patch that was broke from the eh timed out patch.
* 2.6.29-rc libiscsi: Fix scsi command timeout oops in iscsi_eh_timed_outMike Christie2009-02-071-1/+2
| | | | | | | Merge upstream fix for command timeout oops (iscsi command does not oops, but if a command from another driver timesout that will oops, because iscsi was missetting the default transportt to its time out handler).
* PATCH: fix iBFT firmware reading with newer kernelsMike Christie2009-02-021-27/+34
| | | | | | | | | | | | | | | | Patch and mail from Hans De Goede: Hi, While testing I noticed that "iscsiadmin -m fw" does not work properly on newer (rawhide atleast) kernels, the attached patch (already applied to the Fedora devel packages) fixes this. Regards, Hans
