* iscsid safe session logoutChris Leech2015-03-021-0/+3
| | | | | | | | | | | | | | | | Implement a safe logout option, which uses libmount from util-linux to check for active mounts (and swaps) over devices, their partitions, and any holders (like LVM and multipath device maps). When enabled iscsid will refuse to logout of sessions actively being used for mounts, returning a status of EBUSY to the ipc request. I've made it a configuration option (iscsid.safe_logout) that defaults to "No" to preserve the existing behavior as the default, while making it available for users that prefer a safety check. This does add a new dependency on libmount. Signed-off-by: Chris Leech <cleech@redhat.com>
* iscsid: add example unit files for systemdTomasz Torcz2012-12-142-0/+22
| | | | | Those two units, based on the work by Jóhann B. Guðmundsson, exploit on-demand socket activation in iscsid.
* iscsi tools: create def ifaces on demandMike Christie2012-03-221-3/+0
| | | | | This has iscsiadm/iscsid create the def ifaces when they are first read.
* init: update red hat init script for module changesMike Christie2012-03-221-2/+3
| | | | | | | This has the red hat init script use iscsiadm to load the proper drivers. The call to iscsiadm -m iface is needed to setup the default iface bindings and load the offload drivers.
* iscsiadm: add netconfig supportLalit Chandivade2011-08-141-0/+135
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 1. Current status: Using iscsiadm one cannot do any network configuration for qla4xxx adapters. However an iface is created for the qla4xxx ports using the hwaddress. \# ls /etc/iscsi/ifaces/ iface.example iface0 qla4xxx.00:0e:1e:04:8b:2a qla4xxx.00:0e:1e:04:8b:2e This allows user to issue sendtargets via the qla4xxx iscsi offload. 2. Current Proposal: Current proposal is to allow iscsiadm to configure the network settings for qla4xxx ports. This implementation is based on discussions at - http://marc.info/?l=linux-scsi&m=127066184916180&w=2 - http://groups.google.com/group/open-iscsi/browse_thread/thread/d8e8c2df71c95d69/8f731d95d46141a0?lnk=gst&q=iscsi+hba# 2.1 Changes in iscsiadm/iscsid 2.1.1 Add a new event: ISCSI_UEVENT_SET_IFACE_PARAMS 2.1.2 New structure/enum to represent a single network parameter - enum iscsi_net_param; - struct iscsi_iface_param_info; 2.1.3 Added new parameters in iface 2.1.4 Change in operations Add two new operations to iscsiadm apply: Apply the single iface settings applyall: Apply the iface settings of all iface having the same MAC address 2.2 Changes in sysfs network representation The new sysfs directory would look like this:- /sys/class/iscsi_iface/-| _______________________| | |- ipv4-iface-<host_no>-<iface_no>/ <-- for ipv4 |- bootproto |- enabled |- ipaddress |- subnet |- gateway |- mtu |- port |- vlan |- vlan_enabled |- vlan_priority |- ipv6-iface-<host_no>-<iface_no>/ <-- for ipv6 |- enabled |- ipaddr_autocfg |- ipaddress |- link_local_addr |- linklocal_autocfg |- mtu |- port |- router_addr |- vlan |- vlan_enabled |- vlan_priority 3.

The multiple IO Vector mechanism is used to send netconfig parameter from user space to kernel using Netlink interface. IO Vector 0 is used for Netlink message header. IO Vector 1 is used for iSCSI User Event (ev). - The ev will be sent down with event type = ISCSI_UEVENT_SET_NET_CONFIG IO Vector 2 onwards, each vector consists of the struct iscsi_net_param with parameter name followed by its value. The total size will be addition of all the IO vector sizes. 3.2 Kernel space code: - Once event is received, the buffer will look like struct iscsi_net_param with parameter name followed by its value, then next parameter and its value and so on. - the scsi_transport_iscsi would call the adapter's transport->set_net_config - In set_net_config each individual param can be decoded and set into the hardware. 4. qla4xxx configuration: iscsid, creates the iface for qla4xxx, based on the hwaddress. To display the iface related to qla4xxx execute following \# iscsiadm -m iface qla4xxx.00:0e:1e:04:8b:2e qla4xxx,00:0e:1e:04:8b:2e,<empty>,<empty>,<empty> qla4xxx.00:0e:1e:04:8b:2e.ipv6 qla4xxx,00:0e:1e:04:8b:2e,<empty>,<empty>,<e mpty> qla4xxx.00:0e:1e:04:8b:2a qla4xxx,00:0e:1e:04:8b:2a,20.15.0.66,<empty>,<emp ty> qla4xxx.00:0e:1e:04:8b:2a.ipv6 qla4xxx,00:0e:1e:04:8b:2a,2001:DB8:1111:2222::8888,<empty>,<empty> qla4xxx.00:0e:1e:04:8b:2a.ipv6.1 qla4xxx,00:0e:1e:04:8b:2a,2001:DB8:4444:5555::9999,<empty>,<empty> To setup network configuration there can be two methods 4. 1.

* Implement leading-login supportJim Ramsay2011-07-071-0/+4
| | | | | | | | | | | | | | Leading-login only takes effect when performing "login-by-startup" (ie, iscsiadm -m node -L ...). For any nodes with the new 'node.leading_login' config value set to "Yes" (The default is "No"), a login attempt will be made on each successive iface record until one succeeds. The intent is to only have a single iSCSI session for each configured target at startup but also allow for fallthrough to alternate ifaces in case of network issues.

| | | | | | | | | | If a record has this set to anything other than the default value of 1, performing a login with this record will ensure that at least that number of sessions are present for that recordr: The code counts the number of sessions currently active for this record, and will perform multiple logins if the count is less than nr_sessions.

| | | | | | | | | iscsiadm/iscsistart return a mix of type of returns codes. Sometimes -1 and sometimes a EXYZ type of error code. This patch has them return a ISCSI_ERR value. See iscsiadm man page EXIT STATUS section for error code definitions.
* iscsid: use isns discovery rec for isns discoveryd setttingsMike Christie2010-07-011-40/+0
| | | | | | | This patch has isns discoveryd use the isns discovery rec settings instead of the iscsid.conf ones, so that the set up the is the same as ST and to give us freedom in the future to add more settings.
* iscsid: fix sendtargets discovery daemon CHAP handlingMike Christie2010-07-011-34/+0
| | | | | | | | | | | | | | | We may need to have different CHAP settings for each discovery portal. This patch has us use the discovery records instead of the iscsid.conf method of specifying the sendtargets info. If the discovery record has discovery.sendtargets.use_discoveryd = Yes then iscsid will use that record to do sendtargets discovery. The poll interval can be set with discovery.sendtargets.discoveryd_poll_inval.
* iscsi scripts: use iscsiadm -k to shutdown daemonMike Christie2010-06-102-2/+2
| | | | | | | | | | | This has the suse and red hat scripts use the iscsiadm kill command to shutdown the daemon. This is needed so if the discovery daemon is used then it will be cleanly stopped. This does not modify the debian script because I was not sure what the start-stop stuff was doing and did not want to add a bug.
* iscsid: add isns discovery daemon and SCN supportMike Christie2010-03-221-0/+48
| | | | | | | | | | | | | | | | | | | | | | | | | | This adds the following params to iscsid.conf discovery.daemon.isns.addresses discovery.daemon.isns.poll_interval These work like SendTargets where if you the param iscsid will do discovery and log into the portals found. This also adds iSNS SCN support. Like the other code it only supports login of new targets. Some notes: - It does not appear to work with the Microsoft iSNS server shipping with Windows 2008 rc. I have not tested 2003. The server does not seem to be sending any SCNs and at the same time when we register for SCNs it tells us the operation was successful. From the Microsoft docs it appears that the server does not support SCN events. - Linux-isns is not working with our code. The Linux-isns code appears to be sending iSNS SCN pdus with an incorrect format. - It is working with open-isns.git.
* iscsi tools: add MaxXmitDataSegmentLength paramMike Christie2010-03-221-0/+9
| | | | | | | | | | | | This adds a MaxXmitDataSegmentLength param to iscsid.conf. It will limit the size of the pdu we send to the target. If you set it to 0, then we use the old behavior where we just use whatever the target requested. If you set it to a valid value then we use the min of the set value and what the target requested.

* iscsi tools: use open-isns servicesMike Christie2010-03-221-7/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This replaces the native isns code with open-isns's libisns. I included the open-isns code in the open-iscsi tarball to make distribution easier since some distros use different isns clients and may not want to carry open-isns. This is based on open-isns commit 5e09f36d3446e41de0b8361601ffec4cd140d513. Changes in iSNS behavior/use: - To do discovery you must pass the ip and optionally the port to iscsiadm: iscsiadm -m discovery -t st -p 10.15.0.9 This command accepts the same ops as sendtargets so you can add/remove/update the node records that are created. It also supports ifaces properly now. - isns.address and isns.port in iscsid.conf are no longer used. - ESI is temporarily not supported. This will be fixed in the next patch when SCNs support is added. - The iscsiadm isns discovery command is not marked as stable. Signed-off-by: Mike Christie <michaelc@cs.wisc.edu>
* iscsid: have iscsid watch for new portals using sendtargetsMike Christie2010-03-221-0/+26
| | | | | | | | | | | | | | | | | | | | | | | | | This patch has iscsid do SendTargets to the addresses pointed to discovery.daemon.sendtargets.addresses iscsid.conf. It will do it every discovery.daemon.sendtargets.poll_interval seconds. This is useful for setups where the target returns only the valid portals and you want to log into all the portals returned. If the target returns all portals, then this still works, but it is a little loud when a login fails. Notes: - It will use the ifaces setup in /etc/iscsi/ifaces. - For iscsi settings it will use the /etc/iscsi/iscsid.conf settings. - It currently only logs into new targets. It does not remove old ones. You have to run iscsiadm -m session -r $SID -u to remove stale sessions. Signed-off-by: Mike Christie <michaelc@cs.wisc.edu>

* [PATCH] Don't kill iscsid if logout from all nodes failMike Christie2009-07-293-1/+33
| | | | | | | | | | | | | | | | | | | | | | | Patch and email from Erez: If 'iscsiadm -m node --logoutall=all' fails when stopping the open-iscsi service, we shouldn't kill iscsid. This solves the following race: 1. A logout from a node is initiated by the user. 2. Before the logout completes, the user runs /etc/init.d/iscsi stop. The 'stop' method logs out from all nodes. When it tries to logout from the node that is already logging out (step #1), it fails because it is already logging out. Then, the 'stop' method kills iscsid. 3. The logout command form step #1 returns and notifies the (dead) daemon. Now, running 'iscsiadm -m session' shows a session (which, actually, doesn't exist anymore) and the iscsi service is down.

* iscsi conf: increase default MaxRecvDataSegmentLengthMike Christie2009-03-141-3/+2
| | | | | | | | 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 Christie2009-03-141-0/+21
| | | | | | | 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.

* modify initial login retry maxMike Christie2008-09-241-4/+18
| | | | | | | | | | | | | | | | | | | | Now the retry count only controls the number of retries that we attempt when the initial login attempt timesout. It used to control the retry count for any error, which resulted in it having to be set really high and it was also difficult to figure out what to set it to since users (and me) have no idea how quickly the network layer will return errors in some cases. The retry count is also used to determine the max amount of time to wait for the initial login attempt. We do this by: login retry max * login timeout = max time This makes it easier for the user to calculate the max time that they will have to wait. The default time to wait is now 2 minutes for normal sessions and 7 minutes for root.
* iscsi conf: partially revert increase default login max changeMike Christie2008-09-241-3/+3
| | | | | | | | | | | 45 is too high if the connection is timing out. It is 45 * 15 seconds. This sets the retry limit to 8, which would make the connection timeout wait 2 minutes. This is still to few retries for the static ip problem, so in the next patch we will modify iscsid so it retries connection errors like this up to login_timeout * login_retry seconds. This would be 2 minutes which is working for the bug reporters on the list.
* iscsi conf: increase default login maxMike Christie2008-09-241-2/+5
| | | | | | | initial_login_retry_max is too short to be useful. We are getting a lot of login problems due to the EHOSTUNREACH static ip address, so this patch increases the default initial_login_retry_max to 45.
* pass ep to session creationMike Christie2008-05-191-1/+1
| | | | | | | | | | bnx2i allocates a host per session and iser accesses the device so we need to pass them a the leading connection so they can find the hardware that is it bound to. This also has us call ep_disconnect before calling the stop conn callout, so these driver do not have to worry about stopping the receiving path.
* Support mutlple ifaces with the same binding (lack of binding).Mike Christie2008-04-221-1/+6
| | | | | | | | | | | | | | | | | | | | | | If you wanted to be able to create multiple session to the same target portal, then you can now do iscsiadm -m iface -I iface0 -o new If you want to, set a binding: iscsiadm -m iface -I iface0 ....set your binding repeat iface creation iscsiadm -m discovery -t st -p ip:port -I iface0 -I iface1 -I .... or you can create and bind statically iscsiadm -m node -T my_target -i ip:port,tpgt -I iface0 -I iface1 -I .... then login like normal. Or you can login/logout of specific ifaces like with the normal binding. There is one known bug where discovery is not printing the portals and binding setup nicely.

* Add bind by initiatornameMike Christie2008-04-201-5/+19
| | | | | | | | | | | | | | | | | | | | | | You can now setup the initiator to use multiple initiatornames which may come in handy for virtualization. To setup a iface with inames do: iscsiadm -m iface -o new -I iname0 iscsiadm -m iface -I iname0 -o update -n iface.initiatorname -v "your new name" Then you can bind and use the interface like you would before. QUIRK: Because you can pass in multiple ifaces to the discovery command we use the default initiator name in /etc/iscsi/initiatorname.iscsi for the discovery session. node.transport_name is no longer supported. In the next patches you will be able to use the default ifaces for these transports. Signed-off-by: Mike Christie <michaelc@cs.wisc.edu>

It is mostly for testing, iscsi boot or system shutdown. TODO: - more testing. I am pretty sure the original code is broken. For exmaple sending a SIGTERM to the log process then the daemon process will cause semop errors.
* allow setting of scsi eh timeoutsMike Christie2007-10-241-0/+11
| | | | | Allow users to change the scsi eh timeout settings and expose in sysfs.
* mv nop handling to kernelMike Christie2007-08-271-12/+7
| | | | | | | During root boot and shutdown the target could send us nops. At this time iscsid cannot be running, so the target will drop the session and the boot or shutdown will hang. This patch moves the nop handling to the kernel.
* add device reset support and fix some scsi eh bugs.Mike Christie2007-08-141-0/+16
| | | | | | | This patch adds logical unit reset support. It also fixes a bug where when the session lock is dropped so we can grab the recv lock, the iscsi eh thread could grab completely clean up the session. The recv lock would then be a null ptr.

| | | | | | iface (driver and hardware are bound). Also merge the -D and -I arguments so they are now -I driver,hwaddress. Also add some basic qla4xxx support. We can rescan/scan it and perform sendtargets through it but it stores the targets it finds in Flash and then logs into all of them autmatically (when we do discovery and later when reload the driver). So qla4xxx support is mostly to make sure we have the --interfae argument right. We will have to decide how to set other params, manage nodes, and if we should move scanning to the kernel and then also move some error recovery code to the kernel (today qla4xxx is calling block directly and is not able to export it iscsi state yet (the beginnings to fix that is in the git tree but we still need to reduce some code duplcation)). qla4xxx behavior and functionality is going to change as we learn more about the hw (what format the flash data is supposed to be in for example). git-svn-id: svn://svn.berlios.de/open-iscsi@816 d7303112-9cec-0310-bdd2-e83a94d6c2b6
