This method deletes a room (lab) from the DB and deletes on cascade
computers and computers partitions.
Note: if the room id do not exists in the database, ogserver still
tries to delete it and replies with 200 OK.
Request:
POST /room/delete
{
"id": "1"
}
Response:
200 OK
This method deletes a center from the DB and deletes on cascade
rooms/labs, computers and computers partitions.
Note: if the center id do not exists in the database, ogserver still
tries to delete it and replies with 200 OK.
Request:
POST /center/delete
{
"id": "1"
}
Response:
200 OK
If a probe response contains speedinformation, parse and store
it inside the client struct. Speed is interpreted as an unsigned
integer representing Mbit/s.
Avoids multiple entries of a same client like
{"clients": [{"addr": "192.168.2.230", "state": "WOL_SENT"}, {"addr": "192.168.2.230", "state": "OPG"}]
These can arise when ogserver processes a WoL request for an already
connected client.
When processing the WoL request, search for the target address in the
clients list, if found we avoid creating the wol entry.
Otherwise, copying response json to response buffer could lead to stack
smashing is the json response is too large.
stdout example:
*** stack smashing detected ***: <unknown> terminated
Adds POST method to add centers (organizational unit), required payload
parameter is the name, and an additional comment is optional.

ogServer gets netmask address from computer (ordenadores) table, see
commit a35b7c4. Netmask field is empty in most cases, is only filled
when the user adds computers with dhcpd.conf syntax and cannot be edited
in computer properties view.
Labs/rooms (aulas) table also have netmask field, WebConsole backend
ensures it is not empty and can be edited in lab properties view.
Get netmask from labs table to ensure it is not empty.
Tests for e68fefe were made after 00pm (12:00) so we did not cover <12:00 cases
for immediate commands that are logged (scheduled for the exact moment
they are processed and ignored the fact they are stale so they are executed
right away)
In addition, libdbi was complaining about the data type used to
represent the hours, they were not being inserted properly. From syslog:
failed to query database (og_dbi_schedule_create:3288) 1264: Out of
range value for column 'horas' at row 1
Fix og_tm_hours_mask so <12:00 immediate schedule is handled correctly.
Change return type to uint16_t, as the 'hours' column type is smallint(4)
Fixes e68fefe ("#997 Set stale check flag when processing schedule/create")
Commit e68fefe introduced 'check_stale' flag to better distinguish
real scheduled actions that do not execute if they are stale from
immediate actions that we want them to be logged in the action queue
(by creating a decoy schedule for the exact moment they are processed,
meaning that we ignore if the are stale).
Add this feature into schedule update too, in order to avoid executing
stale commands that were not meant to, ie. real scheduled commands.
Follows e68fefe ("Set stale check flag when processing schedule/create")

These strdup are not necessary because the dbi result is not freed
before using them, it's safe to use the dbi result's reference to
this string.
Fix previous memleaks when executing scheduled commands, procedures
and tasks.
If you schedule a command in the past, the scheduler executes such
command immediately.
When expanding a schedule that result in commands that run weekly,
commands in the past are also executed, which is not expected.
Fix this by using the check_stale flag (formerly on_start) so
commands in the past that result from expansions are skipped.
image_json object is created to store the json representation of
an image returned by the database. This object is going to be appended
to a json list that will compose the overall root json object.
Use json_array_append_new to let "images" steal the reference of
image_json so when further decref(root) there is no json reference
hanging around.
Allocated strings using dbi_result_get_string_copy are not being freed
after using them. This patch fix this memory leak.
Fixes: e4cb91b ("#990 wol: migrate mac and netmask query to ogServer")
UMA and UPV report that Wake on LAN command (in queue mode) does not
work.
We improved WoL command, now ogServer calculates the broadcast address
of the network to which the client belongs. To calculate this address
ogServer needs the IP and the netmask of the client. We updated ogServer
to retrieve the netmask from the database in non-queue mode, but we forgot
to add this in queue mode.
This patch adds netmask retrieving to queued WoL.
ogServer WoL rest function is expecting ip, mac and netmask from the
request's payload. This makes the client responsible for providing such
data.
ogServer should be the owner of the database, this patch adjusts the
parameter expected in a request payload for /wol action so clients only
need to provide the ips and wol type (broadcast, unicast).
Database is expected to contain valid data for the netmask and mac of
target computers.
og_cmd_get_client_setup is querying the database for computers disk
setup information. This includes the size of a disk or a partition,
which are stored as BIGINT in the database.
Using dbi_result_get_int will result in an error as libdbi expects to
store this kind of data type in a long long instead of an int.
Fix disk size variable declaration and use the correct dbi_result_get
function for this particular data column.
UMA reports that the setup command (in queue mode) does not work.
WebConsole stores queued commands in the database using the deprecated
SocketHidra legacy string format and ogServer parses them with sscanf().
The setup command has a new field "ttp" since commit 0dd3edd, however,
the ogServer legacy parser was not updated to use this new field.
This patch adds legacy setup support to work with GPT tables. Add new field
table type to legacy setup that expects a string with "MSDOS" or "GPT".
UMA reports that the restore image command (in queue mode) does not work,
the non-queue mode works fine though.
WebConsole stores queued commands in the database using the deprecated
SocketHidra legacy string format and ogServer parses them with sscanf().
The restore-image command has the field "ptc" which stores a string
with whitespaces, however, ogServer expects no whitespaces ("%s").
Update parser to read until carriage return, whitespaces included.
When executing og_cmd_post_modes ogServer is looking up for the template
related to the mode coming as a parameter. This lookup is only done for
the bios boot mode. (ie. /opt/opengnsys/tftpboot/menu.lst/templates/)
Templates can be created for a given boot mode, for example you can
create a UEFI-only template (it.
/opt/opengnsys/tftpboot/grub/templates).
When a UEFI only template was coming as a parameter to og_cmd_post_modes
the file can't be located because the UEFI template folder is never
tested.
Add UEFI folder to the lookup of pxe templates, try this folder if bios
mode fails.
PS: Later on a bash script "setclientmode" is to be executed, which will
take its own way of updating these pxe files (ie. templates/../), this
script updates every boot mode if an available template is found.
ogServer /setup do not support to indicate which table type the user
want to use. It always supposes that the partition table is MBR/MSDOS.
Add ogServer support to work with GPT tables. Add new field table type
to /setup that expects a string with "MSDOS" or "GPT".
Example old JSON:
{
"clients": [...],
"disk": "1",
"cache": "0",
"cache_size": "0",
"partition_setup": [...]
}
Example new JSON:
{
"clients": [...],
"type": "GPT",
"disk": "1",
"cache": "0",
"cache_size": "0",

In case the DB entry for an image does not exist when POST /image/create
is called, this patch takes care of calling it.
This adds few optional json parameters to the POST /image/create API. If
optional parameters are included then this patch creates the DB entry,
otherwise it just creates the actual image and updates the existing
entry.

Use og_server_cfg everywhere. Convert port to string to make it easy for the
dbi API since it expects a string. Remove legacy example configuration file.
This patch is a refactor for og_computer and og_dbi_get_computer_info.
It now uses fixed lenght strings to make it more reliable and avoid
errors if the DB is not returning a null ended string.
