* Add in tracking IP prefix length, in addition to mask.Lee Duncan2018-01-181-0/+1
| | | | | The modern IP standard stresses the IP prefix length rather than the mask, so track the IP prefix length.
* Fix duplicate define of __bitwiseLee Duncan2017-12-021-0/+2
| | | | | | Gcc version 7.2.1 and linux glibc devel version 4.14 define __bitwise and does not need open-iscsi to do it, so check for define before doing it ourselves.
* iscsi_if.h: use attribute instead of '__packed'Khazhismel Kumykov2017-09-051-1/+1
| | | | | | More consistent, doesn't rely on __packed being defined in userspace. Signed-off-by: Khazhismel Kumykov <khazhy@google.com>
* iscsiuio must be present to use hardware offload for bnx2{,x}Andrew Patterson2017-06-021-0/+1
| | | | | Check for the presence of /sbin/iscsiuio before using hardware offload for bnx2 and bnx2x devices.
* iscsistart: support booting over a VLANChris Leech2016-04-121-1/+2
| | | | | | | Adds code to check for VLAN devices if the boot configuration specifies a VLAN ID. Does not create VLANs, they need to already be in place.
* iscsiadm: fix parallel rescan handling of exit codesChris Leech2016-04-121-0/+2
| | | | | | | | | | | | | | | | | The parallel rescan patches work, in so much as the rescans happen, but if a target is specified the non-matching cases cause warning to be printed and a non-zero exit code. To reproduce: have more than one session to different targets, issue a node mode rescan command to one of them (-m node -T <iqn.target> -R). The problem is that while exit() takes an int, only the low byte is part of the exit code and it's combined with other exit status information. iscsiadm tries to use exit(-1) to indicate a non-match (not a fatal error). The value retrieved with wait() after an exit(-1) is actually 65280. Fix this by making use of the wait.h macros for checking the exit code.
* Make running actors event-drivenAndy Grover2015-01-121-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | Instead of waking up frequently to check if actors need to run, set an alarm for the first timeout and use a signalfd to get us out of poll() when the alarm expires and SIGALRM is sent. alarm(2) only has second granularity but we are using delayed actors for multi-second timeout handling so this is ok. All callsites were multiplying by 1000 for wait-in-msec, so just change actor_timer() callsites to pass timeout in seconds. Fold actor_check() into actor_poll(). Remove actor_timer_mod, not used. Rename actor_list to ready_list for clarity. Remove poll_list, no longer needed. Remove ACTOR_POLL_WAITING state, no longer needed. Add some more helpful macros to list.h.

* fwparam_ibft: Check iBFT target and NIC flagsHannes Reinecke2014-11-141-0/+2

* Represent DHCP "origin" as an enum, not a string.Hannes Reinecke2014-11-141-1/+10
| | | | | | | | | | | | | | | See IBFT standard for location of "origin" field in iBFT table, and see MS document: http://msdn.microsoft.com/en-us/library/aa366281.aspx for description of enums, duplicated here in part: typedef enum { IpPrefixOriginOther = 0, IpPrefixOriginManual, IpPrefixOriginWellKnown, IpPrefixOriginDhcp, IpPrefixOriginRouterAdvertisement, IpPrefixOriginUnchanged = 16 } IP_PREFIX_ORIGIN;
* Parse 'origin' value from iBFTHannes Reinecke2014-09-041-0/+1
| | | | | | | | | | | iBFT has an 'origin' field which indicates the origin of the network address. If that is set to '3' it indicates that DHCP has been used; there is no need to evaluate the 'dhcp' field here. In fact. latest iPXE sets the 'origin' field, but not the 'dhcp' field.

* 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.

* iscsi tools: convert discovery code to iscsi error codesMike Christie2011-01-311-0/+4
| | | | | This just converts the iscsi discovery code to the iscsi_err.h error codes.
* iscsid: add new auth error codeMike Christie2011-01-311-0/+2
| | | | | | Add a new auth error code to make it easier for users to tell if it failed due to a auth error vs other target login error.
* iscsi tools: fix iscsiadm exit codesMike Christie2011-01-311-0/+63
| | | | | | | | | 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.
* 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 boot: add support for iscsi boot sysfs moduleMike Christie2010-07-101-0/+2
| | | | | | This patch modifies the ibft sysfs code to support the iscsi boot sysfs module which is used by be2iscsi to export be2iscsi boot info.
* iscsid: support discovery daemon auto logoutMike Christie2010-03-221-0/+12
| | | | | | With this patch, if the sendtargets or isns daemon detects that a target is no longer sent it will logout the session.
* 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>
* iscsi tools: nic setup cleanupMike Christie2010-01-151-2/+4
| | | | | | This just breaks up the network part of the nic setup code to a new function that lives in the net utils code, so it can be used by other callers one day.
* ibft boot: do not setup nic if offload can be usedMike Christie2010-01-151-0/+1
| | | | | | If the nic has a iscsi offload function then do not set up the nic with the ibft net settings. We will use those values for the iscsi net settings.
* iscsi tools: merge functions to get net iface name from mac addressMike Christie2010-01-151-0/+8
| | | | | | There are 3 functions to get the net iface name from the mac address. This merges them into one function and moves it to a new file.
* ibft boot: mv setup nics to fw_entry.c so iscsiadm can use itMike Christie2010-01-131-0/+1
| | | | This just mvs setup_nics to fw_entry.c so iscsiadm can use it.
* iscsi mod: sync to linux-2.6-iscsi tree's 2.6.33 feature window patchesMike Christie2009-11-062-0/+53
| | | | | Sync kernel modules with what is being sent for the 2.6.33 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.
* 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.
