Description:
### System

* xuname: Void 5.4.83_1 armv6l Unknown uptodate rFF
* package: samba-4.14.5_1

### Expected behavior
Being able to start `smbd` with the default configuration.

### Actual behavior
It immediately ends with:
```
exit_daemon: daemon failed to start: Samba cannot setup ep pipe, error code 13
```

### Steps to reproduce the behavior
```
# xbps-install -Suy samba
# smbd -FS -d 10 --no-process-group
    ...
    regdb_open: registry db opened. refcount reset (1)
    make_internal_ncacn_conn: Create pipe requested winreg
    Created internal pipe winreg
    svcctl_init_winreg: Could not open SYSTEM\CurrentControlSet\Services - NT_STATUS_INVALID_HANDLE
    regdb_close: decrementing refcount (1->0)
    dcesrv_init_ep_server: Failed to init endpoint server 'svcctl': NT_STATUS_UNSUCCESSFUL
    dcesrv_init: Failed to init DCE/RPC endpoint servers: NT_STATUS_UNSUCCESSFUL
    main: Failed to setup RPC server: NT_STATUS_UNSUCCESSFUL
    exit_daemon: daemon failed to start: Samba cannot setup ep pipe, error code 13
```
After this, two (forked?) `smbd` processes for the given command will remain, and thus trying to start it from runit with `sv start smbd` will end up filling up the system with `smbd -F -S -d1` processes.

This looks like the same issue that was mentioned by [wangp][1] and [Anachron][2] in #27565 for samba-4.13.2_2.

Could you check what permissions and/or dates your registry.db has?

Comment:
@Anachron sure:
```
-rw------- 1 root root 516K May 20 20:54 registry.tdb
```
This is from before the upgrade - I forgot about its /var/lib/samba directory.
I have now tried to clear it and let `smbd` create the files in it again:
```
-rw------- 1 root root 412K Jul 21 19:14 account_policy.tdb
-rw------- 1 root root  696 Jul 21 19:14 group_mapping.tdb
-rw------- 1 root root 412K Jul 21 19:14 registry.tdb
-rw------- 1 root root 412K Jul 21 19:14 share_info.tdb
```
But it keeps failling with the same errors as above. Did you get to test this package on armv6l?

Sadly no, I have no such hardware.

Thanks for the detailed description. The issue is reproducible in an `armv6l` chroot. Updating to 4.14.6 fixes it for me. PR #32300 submitted, feel free to test.

Comment:
Samba is a known troublemaker for xbps-src. Building a package on a host that has samba-libs installed (even if a server isn't running!) can sometimes cause library dependencies to leak in, causing the resulting package to be totally broken. This kind of error seems to be symptomatic of these problems.

I'm not convinced the upgrade in #32300 isn't an accidental fix, but it would be good to test and that shouldn't block the update either way.

In the meantime, a couple of questions:

1. Is your samba package locally built?
2. If so, is the package natively built or cross-compiled?

If you do build your own package or are keen to test the update PR, best practice is to stop any samba services, completely uninstall samba and samba-libs (including any dependants necessary to make this possible) before building the package.

TIL! :astonished: Not sure I wanna know the details of that. The build host should be a container, no?

Well, I am now. :smirk: Just rebuilding 4.14.5 locally also fixes it (cross). Question is now if the build server build will work this time...

I can reproduce with x86_64 btw, built manually on my machine... I'll try an update.

And I do have samba installed on the build machine.

Comment:
I can confirm this issue is reproducible as well when installing `samba-4.14.5_1` from repo on `armv6l`

I compiled Samba locally (took about 24 hours on 700MHz RPi1!) and the issue is resolved
