2021-03-19lib: Properly return errno from open_socket_in()Volker Lendecke1-78/+79
Before this patch, open_socket_in() relied on quite a bit of code to not touch errno after for example socket() returned -1. Change this to explicitly save errno in "ret", such that a later DEBUG() with all its formatting code can mess it up. While there, remove the debuglevel parameter. I don't think this actually useful.

2020-02-26s3:lib: avoid calling async_connect_send() again and again in open_socket_out*()Stefan Metzmacher1-48/+0
There's really no need to do that! Once connect() is called and returned EINPROGRESS, the kernel knowns what to do and reports any state change via TEVENT_FD_READ or TEVENT_FD_WRITE. The actual success or failure is available via getsockopt(.., SOL_SOCKET, SO_ERROR, ...). Before this commit we called connect() (via async_connect_send()) again and again until we reached the final caller provided timeout, even if the kernel already found out that the destination is unreachable.

Without the umask code the pipe permissions are affected by the umask of the calling process. As only smbd currently sets its umask to zero (nmbd and winbindd should do the same) this causes the winbindd pipe to be unavailable to the nss library code unless winbindd is run from an init process that explicitly sets umask to zero. When testing from the command line this can be hard to track down :-).
