virtio_transport and vmci_transport handle the buffer_size sockopts in a very similar way. In order to support multiple transports, this patch moves this handling in the core to allow the user to change the options also if the socket is not yet assigned to any transport. This patch also adds the '.notify_buffer_size' callback in the 'struct v...

Greetings, I noticed a while back someone posted a patch/plugin that allowed Dovecot to use compressed mbox files. I'm now wondering how far that would put us from having compressed maildir? I have a server with more CPU than disk space, and while I can buy more HDD space, my backup solution doesn't make that practical. It seems to me that when looking for a message file, if it

I'm not sure if this is worth pursuing. On paper, it makes sense (if we know we have multiple commands batched to send over the wire, AND those commands are short in length, we might as well use MSG_MORE), but the measurement numbers with it applied might just be in the noise.

Hi All, After configuring and compiling OpenSSH version 4.6p1 in my SUN Solaris8 ultrasparc machine, I run "make tests" and got the following errors. The compiler used is GCC3.3. run test sftp.sh ... test basic sftp put/get: buffer_size 5 num_requests 1 sftp failed with 1 test basic sftp put/get: buffer_size 5 num_requests 2 sftp failed with 1 test basic sftp put/get: buffer_size 5 num_requests 10 sftp failed with 1 test basic sftp put/get: buffer_size 1000 num_requests 1 sftp failed with 1 test basic sftp put/get: buffer_size 100...

Ok.. I'm starting official testing calls early this release. I'd like to have more feedback and more time for handling fixes. If people could test snapshots (http://www.openssh.org/portable.html, pick your favorate mirror and select snapshots directory) and report failures it would be useful. For those with pmake install there is regress/ which you can try out. It may help any platform
