Is sendpage or some other alphanumeric paging program available from one of the repos for CentOS 5? I've checked rpmforge and epel. I just wanted to check to see if it might be available somewhere else before I resort to building from source. -- Bowie

Fix ocfs2 to use the page fragment allocator rather than kzalloc in order to allocate the buffers for the handshake message and keepalive request and reply messages. Slab pages should not be given to sendpage, but fragments can be. Switch from using sendpage() to using sendmsg() + MSG_SPLICE_PAGES so that sendpage can be phased out.

Now that ->sendpage() has been removed, MSG_SENDPAGE_NOTLAST can be cleaned up. Things were converted to use MSG_MORE instead, but the protocol sendpage stubs still convert MSG_SENDPAGE_NOTLAST to MSG_MORE, which is now unnecessary.

I can't find documentation for ->sendpage(). Is the idea that you get a struct page for the payload and can do zero-copy tx? (And can userspace still write to the page, invalidating checksums in the header?) Stefan -------------- next...

Hey, We are blocked on a bug fixed by RHEL in https://rhn.redhat.com/errata/RHBA-2012-0362.html. Specifically, the splice code in sendfile() incorrectly updating the offset position on the write side, Red Hat BZ#771868. I have not been able to figure out if this bugfix is included in any CentOS releases. If you are better at reading release notes than me, could you please help me out and let me

Hi; Before I tell a customer that this would require custom development I figured I would ask here. Does Asterisk support pager notification of new voicemails out of the box? Or do I need an AGI script to do that? Also, if I want to call a number from an automated program in Asterisk and get the DTMF tones entered by the user on the other side, is there an easy way to do this? Best

This series tries to increase the throughput of virtio-vsock with slight changes: - patch 1/4: reduces the number of credit update messages sent to the transmitter - patch 2/4: allows the host to split packets on multiple buffers, in this way, we can remove the packet size limit to VIRTIO_VSOCK_DEFAULT_RX_BUF_SIZE - patch 3/4: uses

...It looks like it's fixed in the current kernel. Hint: try grepping the package changelog: $ rpm -q --changelog kernel-2.6.32-504.el6.x86_64 | grep sendfile - [fs] Fix sendfile write-side file position (Steven Whitehouse) [770023] - [fs] sendfile(): check f_op.splice_write() rather than f_op.sendpage() (Lukas Czerner) [689426] Those entries seem to match the bug description in the errata you list so I'd guess it's fixed.

I hope someone can help me with this. This is what I want to happen. Someone dials in and goes to my extension. First, the phone on my desk rings If there is not an answer, I would like to have the dialplan call my cell phone. If I answer my cell phone, speak the incomming number to me. I press one of the buttons on my cell phone to accept the call. If I don't answer, or I don't
