************* Module osmo-smdpp
osmo-smdpp.py:657:72: E0606: Possibly using variable 'iccid_str' before assignment (possibly-used-before-assignment)
=> False-positive: code paths that don't set iccid_str raise an error, so
this shouldn't be a problem.
************* Module pySim-smpp2sim
pySim-smpp2sim.py:427:4: E1101: Module 'twisted.internet.reactor' has no 'run' member (no-member)
=> False-positive: pylint doesn't recognize dynamically set attributes
************* Module es9p_client
contrib/es9p_client.py:126:11: E0606: Possibly using variable 'opts' before assignment (possibly-used-before-assignment)
=> Real bug, should be "self.opts"

If TLS is enabled (default) it will automagically generate missing pem files + dh params.
A faithful reproduction of the certs found in SGP.26_v1.5_Certificates_18_07_2024.zip available at
https://www.gsma.com/solutions-and-impact/technologies/esim/gsma_resources/sgp-26-test-certificate-definition-v1-5/
can be generated by running contrib/generate_certs.py. This allows adjusting the expiry dates, CA flag,
and other parameters FOR TESTING. Certs can be used by the smdpp by running
$ python -u osmo-smdpp.py -c generated

We're creating a 'pyosmocom' pypi module which contains a number of core
Osmocom libraries / interfaces that are not specific to SIM card stuff
contained here.
The main modules moved in this initial step are pySim.tlv, pySim.utils
and pySim.construct. utils is split, not all of the contents is
unrelated to SIM Cards. The other two are moved completely.

As SGP.22 states, the handleNotification endpoint uses HTTP status 204,
not 200 (due to its empty body).
Change-Id: I890bdbd3e1c4578d2d5f0367958fdce26e338cac
this way, the eUICC will send us notifications whenever our profiles are
enabled/disabled/deleted.
Change-Id: I2861290864522b691b30b079c7c2e1466904df2d
"other" notifications (enable, disable, delete) contain ECDSA
signatures that also need verification.
Change-Id: If610058b7af6f9fc7822576c93f9970e2ce9aba9
SGP.22 is quite clear in that handleNotification shall return an empty
HTTP response body. Let's make sure we comply to that and don't report
a JSON response.

The eSIM specs allow for both brainpool and nist; in reality the
deployments use the NIST P256 curve.
osmo-smdpp currently only supports a single certificate; let's use the
NIST one by default.

Before this patch we had three different error causes that would cause a
"Verification failed" error message. Let's state explicitly which part
of verification did actually fail.

We used to re-encode those parts of a decoded ASN.1 struct that is
cryptographically signed in the GSMA SGP.22 specification. However, if
the received data follows a later spec and contains new/unknown records,
then our poor-man's attempt at re-encoding will render a different
binary, which in turn means the signature check will fail.
Let's instead do a manual step-by-step raw decode of the DER TLV
structure to extract the actual binary information of parts of ASN.1
objects.

Closes: OS#6473
osmo-smdpp.py:374:72: E0601: Using variable 'iccid_str' before assignment (used-before-assignment)
Let's raise an exception in the erroneous case.

The hex string of the generated transactionId contains lowercase hex
digits. However SGP.22 explicitly spcifies to use uppercase hex digits
when using JSON fromatted messages. See section 6.5.2.6 for example.

Read the ICCID from the header of the UPP when building the
ProfileMetdata. This allows the download of profiles with arbitrary ICCID.

Let's simply use the matchingId for filesystem lookup of the UPP file.
This way we can have any number of profiles by simply creating the
respeective files.

We can only choose a CI certificate which is supported both by the eUICC
as well as which has signed our own SM-DP+ certificates.

This commit introduces
* the osmo-smdpp.py program implementing the main procedures and the
HTTP/REST based ES9+
* python modules for ES8+ and non-volatile RSP Session State storage
* the ASN.1 source files required to parse/encode RSP
* 3GPP test certificates from SGP.26
* an unsigned profile package (UPP) of a SAIP v2.3 TS48 test profile
As I couldn't get the 'Klein' tls support to work, the SM-DP+ code
currently does not support HTTPS/TLS but plan HTTP, so you either have
to modify your LPA to use HTTP instead of HTTPS, or put a TLS proxy in
front.
I have successfully installed an eSIM profile on a test eUICC that
contains certificate/key data within the test CI defined in GSMA SGP.26
