Vhost log dirty pages directly to a userspace bitmap through GUP and kmap_atomic() since kernel doesn't have a set_bit_to_user() helper. This will cause issues for the arch that has virtually tagged caches. The way to fix is to keep using userspace virtual address. Fortunately, futex has arch_futex_atomic_op_inuser() which could be used for setting a bit to user. Note there're several

I have a model with a belongs_to association. The first model is called Thing and the associated model is User. I''m attempting to assign the user to the thing. To accomplish this I used a before_save method, like this: class Thing < ActiveRecord::Base belongs_to :created_by, :class_name => "User", :foreign_key => "created_by_user_id" def before_create

Hi, I am wondering if it's possible to authenticate users that come from specific IP differently then other users. I will be authenticating them by postgresql so something like this would be very useful: password_query = SELECT password from get_user('%username','%host') Is that possible? Can it be done any other way? Thanks, Sebastjan

Hi there, Although I'm a quite experienced R user and know my ways in C, I stumbled upon a problem I don't know how to solve. Therefore, I hope someone can provide me with the information or pointers I need in order to understand the way in which the communication between R and C occurs. I have the following C code which basicallly reflects what I want: typedef struct { float

Hi, Long story short I've got a fully functional Dovecot IMAP instance and I am now looking to upgrade some perimiter authenticated SMTP relays to authenticate against the Dovecot instance. Trouble is that I am seeing errors such as "auth: Warning: sql: Ignoring changed user_query in /etc/dovecot/local_sql_users.conf, because userdb sql not used." in my Postfix server logs and not

For virtualization, we've developed virtio_ring for efficient communication. This would also work well for userspace-kernel communication, particularly for things like the tun device. By using the same ABI, we can join guests to the host kernel trivially. These patches are fairly alpha; I've seen some network stalls I have to track down and there are some fixmes. Comments welcome!

Is there a more elegant way of writing this? def verify_user @user = User.find_by_username params[:username] if @user.nil? message = xml.error do |xm| xm.message "User does not exists: #{params[:username]}" end render :xml => message return false else true end end Thanks, Joel --

This patch move the used ring initialization after backend was set. This make us possible to disable the backend and tweak the used ring then restart. And it's also useful for log setting as used ring have been checked then.
