Allow the userspace libs to specify a driver at runtime
It would be useful to be able to load custom named drivers (e.g. falco-acme) alongside the stock driver (falco).
Currently, this isn't possible because stock libscap is unable to connect to custom-named Falco drivers. This happens because libscap sets the name of the driver at compile time via the environment variable DRIVER_DEVICE_NAME.
From scap_open_live_int():
//
// Open the device
//
snprintf(filename, sizeof(filename), "%s/dev/" DRIVER_DEVICE_NAME "%d", scap_get_host_root(), all_scanned_devs);
Feature
We need to add support for runtime selection of a driver by name.
This can be accomplished by adding a parameter to e.g. scap_open_int_live() and sinsp_open() containing the driver name:
sinsp s;
try
{
// First, try connecting to a custom-named driver.
s.open("acme-falco");
}
catch (sinsp_exception &ex)
{
driverLoaded = false;
}
if (!driverLoaded)
{
try
{
// If unable to connect to a custom-named driver, try the stock driver.
s.open("falco")
}
catch (sinsp_exception)
{
}
}
**Alternatives**
**Additional context**
I think it makes sense!
We might add an optional param to sinsp::open() to retain backward compatibility; then add a new field to scap_open_args.
Would you be open to contribute? ;) Thanks!
