Oliver Smith 81db389fd4 Add IMEI column to subscriber table
Extend the database scheme, add imei to the hlr_subscriber struct and
create db_subscr_update_imei_by_imsi() and db_subscr_get_by_imei(). The
new functions are used in db_test, and in follow-up commits [1], [2].

Upgrade DB schema to version 2. SQLite can only insert new columns at
the end of the table, so this happens when upgrading the database. In
new databases, the column is placed after the IMEISV column (where it
makes more sense in my opinion). This should not have any effect, as
we never rely on the order of the columns in the tables.

Follow-up commit [1] will make use of this column to save the IMEI as
received from the MSC/VLR with the Check-IMEI Procedure. It was
decided to use Check-IMEI instead of the recent Automatic Device
Detection Procedure (which would send the IMEISV) in OS#3733, because
with Check-IMEI we don't need to rely on very recent releases of the
specification.

Stefan Sperling 8f3a7cce80 add database schema versioning to the HLR database
Make use of pragma user_version to store our database schema version.
The present schema is now identitifed as 'version 0', which is also
the default value for databases on which we never ran the statement
'pragma user_version' before.

Only bootstrap the database if it hasn't been bootstrapped yet.
Previously, bootstrap SQL statements ran every time osmo-hlr
opened the database, and any errors were being ignored in SQL.
Instead, we now first run a query which checks whether tables
already exist, and only create them if necessary.
This change will allow future schema updates to work properly.

Prepare for future schema upgrades by adding a new command-line
option which enables upgrades. This option defaults to 'false'
in order to avoid accidental upgrades.

Neels Hofmeyr 2dee60ef44 db_test: also test db_get_auc() return values
Verify that it returns -ENOENT on non-existing IMSI and -ENOKEY for no auth
data.

Move the auc_compute_vectors() stub to the top near the db_get_auc() call, and
just return num_vec to get a successful return value when auth data is present.

Neels Hofmeyr bd1dca0859 db_get_auth_data / db_get_auc: clarify return values
Differentiate between "IMSI unknown" and "IMSI has no auth data": in case of
known IMSI lacking auth data, return -ENOKEY instead of -ENOENT.

Fix API doc comments to reflect what the functions actually return, on top of
adding the -ENOKEY detail.

Adjust db_test expectations from -ENOENT to -ENOKEY where appropriate.

Adjust VTY and CTRL command rc evaluation.

A subsequent patch will use these return values to log details on each of these
situations.

Neels Hofmeyr d3814b936b db_test: don't verify SQLite issued error messages, they might change
A user on openbsc@ complained that with SQLite 3.8.2, the db_test fails with

  --- expected
  +++ stderr
  -DDB (2067) abort at 18 in [INSERT INTO subscriber (imsi) VALUES ($imsi)]: UNIQUE constraint failed: subscriber.imsi
  +DDB (2067) abort at 35 in [INSERT INTO subscriber (imsi) VALUES ($imsi)]: UNIQUE constraint failed: subscriber.imsi

i.e. a trivial difference in the error message issued by SQLite.

For db_test, don't output any SQLite error messages: Add argument
enable_sqlite_logging, pass as true, except in db_test.c.
Remove the SQLite error messages from expected output.

(Note that there is a src/db_test.c program that's not of interest here, this
is about the tests/db/db_test.c)

Neels Hofmeyr 6eb231eccc fix default logging levels to NOTICE, not DEBUG
Tweak unit test binaries to still used DEBUG loglevels, so that their expected
outputs remain unchanged (and nicely verbose).

Adjust test_nodes.vty, now expecting the 'notice' log levels upon
'show running-config'.

Neels Hofmeyr b6837e36a3 fix db_subscr_get_by_*(): clear output data; test in db_test.c
db_subscr_get_by_*() failed to clear the out-param struct, meaning that data
could remain in a struct even though it is not present in the database. Always
zero out the struct before writing to it.

Adjust the db_test to catch this error by writing "-invalid-data-" to each
struct before running db get functions.

Neels Hofmeyr 1cbdb70b27 fix db_update_sqn(): reset stmt in all error cases
Use the common db_bind_int64() so that the stmt bindings are cleared for any
errors and to get error logging for free.

On error with sqlite3_step(), log the SQL error message, and make sure the stmt
is cleared of bindings and reset.

After sqlite3_step(), verify that exactly one row was modifed, log and return
errors otherwise.

After this patch, the DB interaction closely matches the other (refactored) DB
functions.

Neels Hofmeyr 57a8792f23 refactor db_get_auth_data return val
Adopt the error handling of the other db functions: return -ENOENT on unknown
subscriber and -EIO on SQL failure. Return 0 for no error, instead of the
number of rows modified.

Adjust the single caller: db_get_auc()
(and db_test.c).

Neels Hofmeyr 1332a17a3d add db_subscr_update_aud_by_id(), complete db_subscr_delete_by_id()
Add ability to add and remove auc_2g and auc_3g table rows with
db_subscr_update_aud_by_id().

In db_subscr_delete_by_id(), make sure that when deleting a subscriber, also
all auth data associated with that user ID is removed as well. A newly created
subscriber must not obtain the same auth tokens just by getting the same id.

Neels Hofmeyr e8ccd5013a refactor db_subscr_ps() to db_subscr_nam()
Allow to set nam_ps and nam_cs from this same function, by adding the is_ps
arg.

Combine both NAM_PS stmts to DB_STMT_UPD_NAM_PS_BY_IMSI, add another such stmt
for CS. Use named parameters instead of parameter indexes.

Improve error return values as well as error logging to clearly indicate
whether the operation could not find the requested IMSI, or other errors
occured.

Adjust the single caller.

This prepares for upcoming VTY and possibly CTRL commands, and the error
handling introduced here has been or will be adopted by other functions in
previous or subsequent patches.

Add the new functions db_subscr_get_by_msisdn() and db_subscr_get_by_id() and
factor out common parts with db_subscr_get_by_imsi() to static db_sel().
