* #915 Add last_cmd to GET /clients APIJavier Sánchez Parra2022-05-183-2/+45
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | "last_cmd" json object contains information of the last command executed by the correspondent client. For now, it only includes "result" string property, which stores "success" if the last command finished correctly or "failure" on the contrary. To populate "result" property, this commit also adds "last_cmd_result" enum attribute to og_client struct. Client response processing fills this attribute according to its success. Clients in WOL_SENT state always have last_cmd->result = "unknown". Request: GET /clients Response: 200 OK { "clients": [ { "addr": "10.141.10.102", "state": "WOL_SENT", "last_cmd": { "result": "unknown" } }, { "addr": "10.141.10.101", "state": "OPG", "speed": 1000, "last_cmd": { "result": "success" } }, { "addr": "10.141.10.100", "state": "OPG", "speed": 1000, "last_cmd": { "result": "failure" } } ] }
* #915 Add support for link speed in the refresh responseJavier Sánchez Parra2022-05-091-0/+6
| | | | | | | | Add ogServer support for parsing and storing the link speed from ogClient's refresh response. Probe response already has client's link speed, but this API is deprecated.
* #915 Set boot mode to ogLive on client creationJavier Sánchez Parra2022-03-281-0/+8

* #915 release existing client on reconnectionsOpenGnSys Support Team2022-01-213-12/+32
| | | | | Trasient network problems might result in duplicated clients, drop client object if it already exists before creating a new one.
* #915 remove temporary file to store shell outputOpenGnSys Support Team2022-01-184-44/+10
| | | | | Remove legacy behaviour, store it in the client object instead of a temporary file.
* #915 Initialize group when adding a new client to DBJavier Sánchez Parra2022-01-171-1/+2

* #915 consolidate WoL sender functionOpenGnSys Support Team2021-12-226-100/+74
| | | | | | | | This patch aims simplifies the WoL sender routine. A few related changes: - Replace goto err to continue if IP address is malformed - Use ret |= instead of ret &= to accumulate error code.
* #915 remove shim code to update database after image restore commandOpenGnSys Support Team2021-12-223-63/+26
| | | | Make direct call to dbi API to update database instead.
* #915 remove dead code in ogAdmLibOpenGnSys Support Team2021-12-222-50/+1
| | | | Remove declarations that are not used anymore in ogAdmLib.
* #915 Remove useless WoL shim codeOpenGnSys Support Team2021-12-203-50/+43
| | | | | | | Levanta() is not required, iterate over the array of IP address and make direct calls to WakeUp(). This is also implicitly fixing up a memleak in og_cmd_wol().
* #915 Add POST /oglive/set REST requestJavier Sánchez Parra2021-12-171-0/+114
| | | | | | | | | | | | | | | | | | | This patch allows you to update clients' database entry and PXE boot file with the specified ogLive. If you specify either an incorrect or unexisting ogLive, then, clients use the default ogLive image. You can query ogLives installed on the server with ogServer's GET /oglive/list API. If you set the oglive field to "default", then the default ogLive is used. Request: POST /oglive/set { "clients": ["192.168.56.11", "192.168.56.12"], "name": "ogLive-5.4.0-r20200629" } Response: 200 OK
* #1065 split og_status_session_toggleJose M. Guisado2021-12-031-9/+22
| | | | | | | | | | | Handles non usual situations like a client sending more than one event of same type. When toggling, receiving two events of the same type is the same as receiving two different ones (eg. start, then stop). Split into _session_start and _session_stop in order to check valid client status.
* #1065 Add support for client eventsJose M. Guisado2021-12-013-1/+78
| | | | | | | | ogServer supports events from clients in an agent mode (linux/windows). Client sends event information (eg. user login/logout) via a 103 Early Hints http response message.
* #915 Add folders to scopeJavier Sánchez Parra2021-11-261-31/+285
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The database represents rooms groups and computers groups scope sets with "grupos" (groups) and "gruposordenadores" (computers groups) tables respectively. With this commit, ogServer abstracts both sets and offers them though the API as the set "folder". "grupos" table do not only group rooms, it can group other elements of the database. You can see which kind of elements groups looking at the column "tipo". This commit often refers "rooms group" as group and "computers group" as computers. Request: GET /scopes NO BODY Response 200 OK { "scope": [ { "name": "center1", "type": "center", "id": 1, "scope": [ { "name": "folder1", "type": "folder", "id": 1, "scope": [ { "name": "folder2", "type": "folder", "id": 2, "scope": [] }, { "name": "room1", "type": "room", "id": 2, "scope": [ { "name": "folder3", "type": "folder", "id": 3, "scope": [ { "name": "folder4", "type": "folder", "id": 4, "scope": [] }, { "name": "computer1", "type": "computer", "id": 8, "scope": [], "ip": "192.168.56.12" } ] }, { "name": "computer2", "type": "computer", "id": 7, "scope": [], "ip": "172.18.0.71" } ] } ] }, { "name": "room2", "type": "room", "id": 1, "scope": [] } ] } ] }
* #1043 fix timeout refreshOpenGnSys Support Team2021-11-232-18/+15
| | | | | as described by man(3) ev, to make it work with ev_timer_again() otherwise timer might not ever expire.
* #1065 client: add support for ogclient win stateJose M. Guisado2021-11-173-2/+9
| | | | | | | | | ogClient can be run in windows mode, enabling connection with ogServer when running on a Windows machine. Don't expect the same payload in windows mode as a in live or virtual. Client in windows mode does not send partition setup information, only the status/state. (same case for linux mode)
* #1065 client: add support for ogclient linux stateJose M. Guisado2021-11-173-0/+11
| | | | | | | | | | ogClient can be run in linux mode, intended for exposing some ogServer commands when running in a linux distribution. When connecting with a client in linux mode, do not expect a full partition setup response. Just expect a 'status', and then accept the connection without updating any partition information in the database.
* #1064 revisit error handling from ogClientOpenGnSys Support Team2021-11-122-14/+73
| | | | | | | | | | | | | | | | | | | | 200 => successful command, run next pending command 202 => successful command in progress, do not run next pending command 403 => server sent a malformed HTTP header, should not ever happen, close connection (server is buggy?). 500 => client fails to run command, report error and run next pending command 503 => client is busy, report error and do not run next pending command Anything else, should not ever happen (client is buggy?), close connection with client. On error, when processing response from ogClient, do not close the connection, instead annotate in the database that command was not successful and run next pending command. *Only* if client replies status code 500 set last_cmd to UNSPEC so its state is not BSY as reported by og_client_status function and pending cmds can be sent.
* #1042 incorrect initialization of software profiles arrayOpenGnSys Support Team2021-10-201-2/+3
| | | | | | The position 0 of the software profiles array is not initialized, this triggers a bug randomly on image creation if the position 0 comes zero. Adjust the loop to initialize position 0 accordingly.
* #915 Fix create image payload parsingJose M. Guisado2021-10-192-12/+11
| | | | | | | | | | | | | | | | | Commit 141b0797e17f616d6 introduced command scheduling rest api to ogserver. Part of this changeset included og_json_parse_create_image as a utility funtion to parse the json payload of a "create image" command. og_json_parse_create_image did not include the parsing of optional parameters "description", "center_id" and "group_id". New components like ogCP or ogCLI use these parameters. Fix this by adding a struct og_image member to the struct og_msg_params and assigning it when processing a "create image" command. This could be extended to further payload parsing for image related commands in the future.
* #915 Add POST /image/delete methodJavier Sánchez Parra2021-10-041-0/+90
| | | | | | | | | | Delete operation for images stored in the server. It deletes an image from the database and filesystem, thus images must exists in both places. POST /image/delete { "image": "3" }
* #1061 add timeout to pending scheduled commandsJose M. Guisado2021-09-063-0/+14
| | | | | | | | | | | Pending schedule commands can deny ogLive boot of clients due to filling of pending cmd queue with commands such as "Iniciar Sesión". For example: Using RemotePC to serve clients that do not boot into ogLive will fill up the pending command queue with "Iniciar Sesión". Introduce a safety timeout for pending (scheduled) commands to avoid this situation.
* #1054 Fix og_legacy_partition code buffer sizeJose M. Guisado2021-07-261-1/+2
| | | | | | | | | | | The "code" member of the og_legacy_partition is used to hold the string of the partition type *name* for legacy parameter strings. Example: par=2*cpt=LINUX-SWAP*sfi=LINUX-SWAP*tam=10000000*ope=0 Problem: Buffer size is smaller than possible values for this member. Fix: Increase buffer size up to the max length defined in the DB for the corresponding column.
* #1051 Initialize task_id once in og_cmd_post_schedule_commandJose M. Guisado2021-07-221-7/+7
| | | | | | | | Fixes task_id re-initialization in commit 33d8cecfe. Task id is to be initialized with the "session" value and can be done out of the for loop it was before. Avoiding unnecesary snprintf's with the same value.
* #1052 Populate session column when adding actionsJose M. Guisado2021-07-222-3/+14
| | | | | | | | | | | | | | | | If the scope of a command, procedure or task is related to a group of computers then actions associated with that schedule can share the same session value. og_dbi_add_action was not initializing session value, as it is only used for visualization purposes in the legacy web interface. This patch enables og_dbi_add_action to populate session column by assigning it the id value of the first action related to the scope. Example: Power off command for a room scope of 4 clients will result in 4 actions, a power off for each client. The first action id will determine the session value for the rest.
* #1051 Fix command schedule for several clientsJose M. Guisado2021-07-211-3/+24
| | | | | | | | | | | | | A single command can be schedule for several clients. Commit 141b0797e1 introduces a regression when scheduling a command for several clients, the command only executes successfuly for the first one. Fix it by reintroducing the usage of the 'session' column to group a single command into several actions (one for each client), the web console interface already expects this 'session' column to be set accordingly.
* #915 Add POST /task/add methodJavier Sánchez Parra2021-07-013-0/+187
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Adds the possibility to create a task with procedures and other tasks integrated as steps. Note: "steps" parameter is optional and "steps" array object order defines execution order. Request: POST /task/add { "center": "1", "name": "task", "description": "My task", "steps": [ { "procedure": 4 }, { "task": 1 }, { "procedure": 24 } ] } Response: 200 OK This commit also add task case to procedure's step processing. Otherwise, gcc prints the following warning: src/rest.c: In function ‘og_procedure_add_steps’: src/rest.c:4089:17: warning: enumeration value ‘OG_STEP_TASK’ not handled in switch [-Wswitch] 4089 | switch (step->type) { | ^~~~~~

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Adds the possibility to update a procedure with commands and other procedures integrated as steps. Note: "steps" parameter is optional and "steps" array object order defines execution order. Also, if the body has empty steps, the procedure loses its previous steps. Request: POST /procedure/update { "procedure": "34", "center": "1", "name": "procedure-edited", "description": "My procedure edited", "steps": [ { "command": "wol", "params": { "type": "broadcast" } }, { "procedure": 24 }, { "command": "reboot", "params": {} } ] } Response: 200 OK
* Fix procedure id retrieving in steps creationJavier Sánchez Parra2021-06-291-3/+2
| | | | | | Otherwise, procedure id is always zero. Fixes: 1fdb7e6d1cf0709b1079b2d9990c0d53d8740461
* #915 Filter queued commands by idJavier Sánchez Parra2021-06-161-1/+1
| | | | | | | | | | | | ogServer searches queued commands (formerly actions) in the DB by session. This can lead to problems because session is not an uniquely identifier but an identifier that several commands can share to group them. This commit changes query filter from session to id, ensuring correct results This reverts commit d9b6aadf66655a6713bcacb25d2ea6b01c07e3b5.
* #915 Add POST /procedure/run methodJavier Sánchez Parra2021-06-151-0/+97
| | | | | | | | | | | | | | | | | | | Add ogServer support procedure execution. Now users can send a procedure and a list of clients to ogServer, then ogServer breaks down the procedure into commands (formerly actions) and queues them for each indicated client. TODO: Do not reply 200 OK when the procedure do not exist. Request: POST /procedure/run { "clients": ["192.168.56.11", "192.168.56.12"], "procedure": "33" } Response: 200 OK
* #915 Add procedure/deleteJose M. Guisado2021-06-111-0/+62
| | | | | | | | | | | | Delete operation for procedures stored in the database. POST /procedure/delete { "id": "7" } If no procedure is found returns 200 OK but a syslog call is issued to warn so. Such behavior will likely change in the future.
* #915 Revert filtering actions by id to "sesion" in og_dbi_queue_commandJose M. Guisado2021-06-101-1/+1
| | | | | | | | | | | | | | Commit 141b079 introduced a slight change in how rows from table "acciones" are filtered when queuing a command, from "sesion" column to "idaccion" column. This seemed reasonable, as id column is the one autoincrementing. But remotepc queued commands inserting actions id using a timestamp instead of the action row id. See https://github.com/opengnsys/OpenGnsys/blob/c17ffa5d032a82e8eca61481dd8a8adb8b3fc5b1/admin/WebConsole/rest/remotepc.php#L188 Revert said change as long as remotepc keeps such behavior.

* #915 Add schedule/commandJose M. Guisado2021-06-095-9/+495
| | | | | | | | | Enables ogserver to schedule commands (also referred as actions in legacy web console jargon). This feature enables ogserver to write in the "acciones" table in order to have full capabilities for command scheduling purposes, thus not depending in the legacy web console to insert into "acciones" table.
* #941 Free dbi_inst when og_dbi_open fails to connectJose M. Guisado2021-06-011-0/+1
| | | | | | | | | | When trying to open a connection to a database, an instance of libdbi is created before any connection attempt. If connection is unsuccessful then the og_dbi struct is freed but not the libdbi instance member, thus leaking its memory. Use libdbi dbi_shutdown_r to shutdown libdbi instance member before freeing og_dbi struct inside og_dbi_open.
* #942 Add POST /procedure/add methodJavier Sánchez Parra2021-05-311-0/+90
| | | | | | | | | | | | | | | | | | | | | | This method adds a procedure associated with a center to the database. Required payload parameters are center and name, description is optional. Note: ogServer does not allow to add more than one procedure with the same name and center. Request: POST /procedure/add { "center": "1" "name": "procedure1" "description": "My procedure" } Response: 200 OK This commit also adds unit tests for /procedure/add POST method.
