* iscsiadm: Add support to set CHAP entry using host chap modeAdheer Chandravanshi2013-12-221-1/+18
| | | | | | | | | | Provide support to add and update CHAP entry using chap submode of iscsiadm host mode. Both, new and update, iscsiadm operations perform the same function. Currently only one entry can be added or updated at a time. Signed-off-by: Adheer Chandravanshi <adheer.chandravanshi@qlogic.com> Signed-off-by: Vikas Chaudhary <vikas.chaudhary@qlogic.com>

* iscsiadm: add netconfig supportLalit Chandivade2011-08-141-3/+80
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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. Flow: 3.1 User space code: - If user specify --op=update, then just update the iface config file - If use specify --op=applyall then ifaces for the host passed in. and build up the net config buffer. - Note: If --op is "apply" then only settings for single iface is read, the iface provided with -I option is only read. - The net config buffer will look like this. ----------------------------------------------------------------| | iscsi_net_param { | | iface_num = 0; | | len = 4; | | param = ISCSI_NET_PARAM_IPV4_ADDR; | | iface_type = ISCSI_IFACE_TYPE_IPV4; | | param_type = ISCSI_NET_PARAM; | | value[0] = ipaddress[0]; | | value[1] = ipaddress[1]; | | value[2] = ipaddress[2]; | | value[3] = ipaddress[3]; | | } | ----------------------------------------------------------------| | iscsi_net_param { | | iface_num = 0; | | len = 4; | | param = ISCSI_NET_PARAM_IPV4_GW; | | iface_type = ISCSI_IFACE_TYPE_IPV4; | | param_type = ISCSI_NET_PARAM; | | value[0] = ipgateway[0]; | | value[1] = ipgateway[1]; | | value[2] = ipgateway[2]; | | value[3] = ipgateway[3]; | | } | ----------------------------------------------------------------- | | | iscsi_net_param { | | iface_num = 1; | | len = 4; | | param = ISCSI_NET_PARAM_IPV4_ADDR; | | iface_type = ISCSI_IFACE_TYPE_IPV4; | | param_type = ISCSI_NET_PARAM; | | value[0] = ipaddress[0]; | | value[1] = ipaddress[1]; | | value[2] = ipaddress[2]; | | value[3] = ipaddress[3]; | | } | ----------------------------------------------------------------- ----------------------------------------------------------------- | iscsi_net_param { | | iface_num = 0; | | len = 4; | | param = ISCSI_NET_PARAM_IPV4_GW; | | iface_type = ISCSI_IFACE_TYPE_IPV4; | | param_type = ISCSI_NET_PARAM; | | value[0] = ipgateway[0]; | | value[1] = ipgateway[1]; | | value[2] = ipgateway[2]; | | value[3] = ipgateway[3]; | | } | ----------------------------------------------------------------- | iscsi_net_param { | | iface_num = 1; | | len = 1; | | param = ISCSI_NET_PARAM_IFACE_ENABLED; | | iface_type = ISCSI_IFACE_TYPE_IPV4; | | param_type = ISCSI_NET_PARAM; | | offset = 0; | | value[0] = 0; /* 0 = disable, default = 1 = enable */ | | } | ----------------------------------------------------------------- Each netconfig parameter has different size requirement for value field. e.g.: IPv4 address requires 4 bytes, IPv6 address requires 16 bytes etc. The memory allocated for each netconfig parameter is size of iscsi_net_param + length required for that parameter. 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.

* Use pass through interface for sendtargets (take4) Currenly offload cards ↵Mike Christie2011-01-311-1/+5
| | | | | | | | | | | | | | | | | | like bnx2i, be2iscsi, cxgb3i must use a normal eth for discovery. This patch allows us to do discovery using the iscsi class passthrough interface. Note1 that the dirver must set the CAP_TEXT_NEGO setting, which might requires scsi-misc. Limitations of patch: - MaxRecvDataSegmentLength is limited to 8K for discovery sessions when offload is used. V3: - bug fixes from Eddie Wai to call start conn after we have logged in. Fixed set param not setting all settings. Misc cleanups. V4: - fix iscsistart segfault due to missing initialization.

* iscsi tools: use open-isns servicesMike Christie2010-03-221-2/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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>

* bind offloaded connection to portMike Christie2009-05-101-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | 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.
* iscsi tools: convert from strncat to strlcatMike Christie2009-02-071-0/+27
| | | | | We messed up strncat in so many different ways that strlat could fix. This patch converts the userspace uses of strncat to strlcat.
* iscsi mod: sync up kernel modules with 2.6.29Mike Christie2009-01-211-2/+5
| | | | | This takes the iscsi modules that are planned for 2.6.29 and adds them to the kernel dir.
* iscsi modules: fix compilationMike Christie2008-11-271-0/+2
| | | | | | | | I added a stdint include so that it would be easier to compile userspace apps including iscsi_proto.h, but that breaks the kernel compilation. Since this iscsi_proto.h is only used in open-iscsi releases I am just adding a ifdef __KERNEL__.
* fwparam: rm unused filepath argumentMike Christie2008-11-261-1/+1
| | | | fw_get_entry's filepath is always NULL, so this patch removes it.
* ibft: add support to use iscsi_ibft module and log into all portals found in ↵Mike Christie2008-11-263-9/+121
| | | | | | | | | | | | | | | | | | | | | firmware This adds the ibft sysfs module (iscsi_ibft) parsing support. It was original done by Konard, but I have ported it to use the sysfs.c helpers (add new ones and ported iscsi_sysfs.c too). This patch also modifies iscsistart and iscsiadm to print/log into all the portals found in firmware. It also changes the behavior of iscsiadm -m discovery -t fw so that we create db records for what is found. It is not fully hooked into the iface code, so it will use the different inititor name, but it will not create a iface for it (this means that if you have a record for the same portal that is bound to a iface with a iname you can run into problems).
* iscsi_tcp: return a descriptive error value during connection errorsMike Christie2008-09-251-0/+1
| | | | | | | | The segment->done functions return a iscsi error value which gives a lot more info than conn failed, so this patch has us return that value. I also add a new one for xmit failures. Signed-off-by: Mike Christie <michaelc@cs.wisc.edu>
* handle ISCSI_ERR_INVALID_HOSTMike Christie2008-09-251-0/+1
| | | | | | | | | | If the kernel throws ISCSI_ERR_INVALID_HOST then the host is no longer able to support iscsi. iscsid should then kill the session. There is no need to logout or do the sync cache from the ubind path, because at this point the transport is dead.

* pass ep to session creationMike Christie2008-05-191-0/+7
| | | | | | | | | | 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.
* Revert Release-transport-entry-when-the-transport-is-unload.patchMike Christie2008-05-191-1/+0
| | | | | | | | | We do not need a new event to figure out that a transport is missing. We can just check before accessing the transport. This reverts the original patch. Signed-off-by: Mike Christie <michaelc@cs.wisc.edu>
* Release transport entry when the transport is unloadedMike Christie2008-04-261-0/+1
| | | | | | | | | | When iscsid detects a new transport (e.g. iscsi_tcp, ib_iser), it allocates an entry for it in the transport list. If the transport is unloaded and then reloaded, iscsid would still use the old transport entry. Therefore, the transport entry must be deleted when the transport is unloaded.

* iscsi class/if kernel: add ifacename attrMike Christie2008-04-201-36/+41

* mv nop handling to kernelMike Christie2007-08-271-0/+11
| | | | | | | 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.
* fix shutdownMike Christie2007-08-271-0/+7
| | | | | | | | | | | | | We were using the device delete sysfs file to remove each device then logout. Now in 2.6.21 and .22 this will not work because the sysfs delete file returns immediately and does not wait for the device removal to complete. This causes a hang if a cache sync is needed during shutdown. This patch fixes the shutdown code so that we remove the target and unbind the session before logging out and shuttdown the session.

* add device reset support and fix some scsi eh bugs.Mike Christie2007-08-141-0/+2
| | | | | | | 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.
* fix DefaultTime2Wait handling and fix libiscsi null ptr ref.Mike Christie2007-08-131-0/+2
| | | | | | | We were not using the DefaultTime2Wait value we negotiated for. We could hit a null ptr in libiscsi if we called stop and the connection had not been setup.
* Finish hooking into toolMike Christie2007-07-251-6/+6
| | | | | | | | | | | Instead of having each parser print its output, make it common in fw_entry.c and make that use the same format and fields as the rest of the tools. Kept the ibft dump code, because it may be use for compat tools for suse. Let me know and I can help on that if you need it. With the hook in though the format for ibft is the same as normal iscsiadm node info so you can just reuse your parsing login for that.
* hook fw programs into iscsi toolsMike Christie2007-07-251-0/+46
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch hooks ibft into iscsiadm and iscsistart. Why do this? It seems easier to be able to just run the same tool we use for normal login. For example in the installer or initramfs we can do this: // This will check for fw crap and if found // log into targets that are found // returns 0 on success and non zero if // there was no fw crap or we could not log // in or some other error. // This will _not_ store any record (text files // with data in it) in /var/lib/iscsi. // It is completely dynamic in that regard. ret = iscsiadm -m discovery -t fwboot -l (fwboot - is a new discovery type I added which is for this fw crap). // For normal iscsi install we can then do: ret = iscsiadm -m discovery -t st -p ip:port -l // This will do discovery to the portal at // ip:port, and now the code supports the -l on discovery, // so it will also log into all the targets found // automagically for the caller. // This will store records (text files with target data in it) // like usual to /var/lib/iscsi. To setup the initramfs then, we just need some variable that tells us if we are doing the fw boot or the pxe net iscsi boot. This could be done by checking iscsiadm or iscsistart like so: ret = iscsiadm -m discovery -t fwboot // no login/-l command this time if ret indicates success, then setup initramfs for dynamic fwboot else do the normal pxe static iscsi root stuff we did. In the initrams fs if using iscsistart we would just do (if this got setup for fw dynamic boot) or it would end up as And if using iscsiadm in the initramfs you can just do iscsiadm -m discovery -t fwboot -l The patch was made using Prasana and Doug's code. I have not tested it. I do not have the hardware handy (no intel card and I got stuck looking for a ppc box with it).
