This commit centralizes equality-check behavior and removes duplicated
macro implementations across protocol stacks.
Major changes:
- add `common/utils/eq_check.h` with shared `_EQ_CHECK_*`,
`EQ_CHECK_GENERIC`, and optional-IE pointer helpers
- replace E1AP/F1AP/NAS local equality macros and call sites with
the shared helpers
- remove duplicated layer-specific error/equality macro definitions from
common headers and switch includes to `eq_check.h`
- update CMake test flags to define `ENABLE_TESTS` for `e1ap_lib`,
and 5GS NAS libraries; drop `E1AP_LOG_ERRORS` - equality-check/error
printing is now consistently controlled by `ENABLE_TESTS`
During refactoring, the previously implemented NSSAI field of the cell
info structure was not written to F1AP ASN.1 structures anymore;
eq_f1ap_cell_info() also conveniently omitted the corresponding equality
check. Add this back so the CU can correctly receive the NSSAI in case
of F1 split operation.
Fixes: f278b00837 ("Add encoding/decoding library for F1AP Setup
Request (Interface Management) ")
Add a new target f1ap_lib that groups F1AP ASN.1 encoding&decoding for
messages defined f1ap_messages_types.h. The objective is to, for each
F1AP message,
- add encoder&decoder (similar to what already exists, but without
mandatory message sending afterwards)
- eq_X() function that checks two messages for equality (to be used
mostly in tests)
- cp_X() function that deep-copies a message, e.g., to be used when
sending ITTI messages, instead of manual copying done currently
- free_X() function that frees the memory associated to a memory, to
avoid memory leaks.
Each message will be tested, notably that encoding&decoding as well as
copying yield identical messages.
The actual message encoding & decoding, tests, and their use will be
done in the forthcoming commits.
