Hello, I used NM 1.32.12 in an embedded environment, I have another daemon which is responsible for creating and monitoring connection profiles via libnm. I recently experienced errors I cannot understand, I received an error "Unable to determine UID of the request" in the completion callback of nm_client_add_connection_async.
Looking at the code , it leads to this function (https://gitlab.freedesktop.org/NetworkManager/NetworkManager/-/blob/1.32.12/src/core/nm-dbus-manager.c#L1580) that return NULL. [https://ci4.googleusercontent.com/proxy/6zeBjIJ9_1GN9F6TRIzIMAOeOK0zzwPXIhgF795TtDB3BVIgW-a2zbawWceUY5BP3HafbOaQptqi7NDmimZBHakqyioKixAb5_YP82nAwWrnJICwcSNn1zFfpHDRzkYIQSEK5nWqLCPo=s0-d-e1-ft#https://gitlab.freedesktop.org/uploads/-/system/project/avatar/411/nm_sticker_blue.png]<https://gitlab.freedesktop.org/NetworkManager/NetworkManager/-/blob/1.32.12/src/core/nm-dbus-manager.c#L1580> src/core/nm-dbus-manager.c · 1.32.12 · NetworkManager / NetworkManager<https://gitlab.freedesktop.org/NetworkManager/NetworkManager/-/blob/1.32.12/src/core/nm-dbus-manager.c#L1580> NetworkManager — network management daemon gitlab.freedesktop.org<http://gitlab.freedesktop.org/> The problem is there are no error/warning logs in NM which could help me to understand (so I guess the various g_return_val_if_fail used in the function are not reached). The only difference I see (beside the error of course) is the completion time between the async request and its response in my daemon (roughly 4 seconds in case of error instead of practically instant). From what I understand, it is related to authorization check but before this error, my daemon managed to create a NMClient and perform various getter on it. Several things that I can add for information: - The system does not use polkit. - NM runs as root and the client runs as a limited user. - The problem is pretty hard to reproduce (see this two times on several thousand of the same sequence). Can you please give advice on how I can investigate more on that ? Maybe some particular traces to activate ? Thank you very much in advance for all the help you can bring.
