I see no changes between 6.0 and 6.0-stable in this area. > Solène Rapenne <sol...@perso.pw> posted: > > > On -current binaries now needs both wxallowed on their mountpoint AND have > > to be compiled with -wxneeded flag. > > > > Maybe this has been backported to 6.0-stable ?

So it expected to see this in dmesg but it is not expected for them to die for this reason. In -current after 6.0 the kernel enforced it strictly for non-WXNEEDED executables for a while and killed the process if it made any W|X map requests. In ports-land after this, many ports gained WXNEEDED annotations so they would run normally and not print a message. After that (and still present) this changed to failing W|X map requests and logging, but not killing the process. In some cases they will accept the failure and handle it gracefully; in most cases they won't. Again those executables with WXNEEDED annotations work normally if they are on a "wxallowed" filesystem.. > Output of mount command: > > /dev/sd1a on / type ffs (local, wxallowed) > > Output of dmesg
