[PATCH 1/3] Documentation and example updates
1) Example code: old libc headers don't have SIOCBRADDIF, and old zlibs don't have gzdirect() -- it's a sanity check anyway. 2) Some people don't build in their source directories, so .config isn't there (thanks to Tony Breeds <tony@bakeyournoodle.com>). 3) Point out that guest and host kernel are usually the same. 4) Set the "no checksum" option on the

[PATCH net] vhost: don't use kmap() to log dirty pages
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

help me understand association attributes
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

Authentication based on client host
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

Calling an array in a struct in C to R
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

Dovecot passdb and postfix login
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

[PATCH RFC 1/5] vringfd syscall
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!

[PATCH 1/2] vhost: init used ring after backend was set
