How to control how udev tags the input devices?

I create virtual devices using uinput that are then properly detected by udev which seems to be assigning a tag like "mouse" or "tablet".



I guess udev does this by judging the capabilities set for the device: if I set EV_REL, udev seems to tag my device as a "mouse", which is good for me, but if I set EV_ABS, udev seems to decide it is a "tablet", which is probably perfectly correct but not what I need. Would it be possible to write some udev rule to ask udev to tag as "mouse" a device even though it has the capability EV_ABS?



The final result that I need is to create a virtual device using uinput, detected as "mouse" (not "tablet"), where I can set absolute coords instead of relative. Would it be possible to do this? Can I force this with a udev rule maybe?



Thanks!

          Postfix configuration issue with fips on centos 7; mailgun relay

          Image
          Clash Royale CLAN TAG #URR8PPP up vote 0 down vote favorite I am trying to setup postfix to relay all mail generated on the local machine via SMTP to a mailgun relay. I have used the mailgun relay before with success on an ubuntu server, but I am migrating to a Centos 7 server which I will be running in FIPS mode. There error log is below, slightly sanitized. I have a small enough network that I choose to have each machine reach out to mailgun individually (this the loopback-only, 127.0.0.0/8 restrictions) and no firewall open port allowing smtp in to the machine. I assume the FIPS mode (and with it disabling of MD5) is causing problems, but I don't know how to overcome it or if it is even possible for tls_fprint to use some supported hash such as sha256 or sha512. However, the relay=none is slightly concerning since I have relayhost set, but perhaps that is because the smtp process is failing? Any help would be appreciated! postconf -n: alias_database = hash:/etc/alia
