Strange error and behaviour with sysutils/fusefs-smbnetfs

[Stefan Lambrev]

Hi,

On recently updated freebsd 11 machine with samba47
and fusefs-smbnetfs-0.6.1_1 creating files on smb mount is impossible.

When I try to create file on the mount receive the following error:

cp /var/log/smbnet.log .
cp: ./smbnet.log: Input/output error

The error message which I receive in debug mode is:

2018-10-08 14:49:42.220 srv(24576)->smb_conn_srv_listen: process query=13,
query_len=8
2018-10-08 14:49:42.221 srv(24576)->smb_conn_srv_fstat: errno=22, Invalid
argument

After this error the file is created with zero size e.g. empty. I can read
and delete the file.

I found this bug report in ubuntu -
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=892841
and this patch -
https://bugs.debian.org/cgi-bin/bugreport.cgi?att=1;bug=892841;filename=0001-fix-opening-a-file-with-O_CREAT-and-reading-created-.patch;msg=10

But unfortunately this workaround leads to another error (e.g. call not
implemented).

A month ago everything worked fine, so I'm suspecting changing default
samba from 46 to 47 (https://reviews.freebsd.org/D16904) as the reason for
this.
