...ut that would pessimize direct calls unnecessarily. It sounds like Linux is already providing its own thunks, so it might be better to for us to go back to the __llvm_retpoline_push external thunk name and then get Linux to provide that thunk ifdef __clang__.

Hello all...new to dovecot and this list. I have a question that may have been answered before, but I can't find anything yet that addresses it directly. I installed dovecot 2.0.8 (+postfix, fetchmail) on a small server to manage several e-mail accounts. I love this software! So, to back to the question: I'd like to archive e-mail as it ages into a single IMAP archive directory.

...adds basic support for SSH connections over Bluetooth RFCOMM sockets. It only adds the autoconf magic, along with support for correctly reporting the peer when sshd has been invoked with the '-i' argument from a Bluetooth d?mon working much like inetd, such as the one I have at http://david.woodhou.se/btserv.c Later patches will add the functionality from 'btserv.c' into sshd so that it can listen for itself, and will add support to the ssh client for making the connections directly; currently my testing uses 'ProxyCommand socat stdio SOCKET-CONNECT:31:3:x1ec1e4e21f000100'...

Good afternoon! I've been looking for a way to avoid having to keep my "master" ssh session open while I have others open. This is particularly a pain when my "master" is an scp connection. After searching the archives, I came up with this thread "ControlPersist and multiple X11 forwardings." However, I can't find anything saying that it was

Hi there, I would like to have SSH connections be more "sudo-like". With that I mean, when I ssh/scp/sftp to a host and disconnect, the channel is held open for a while in case I reconnect. I wrote a script (attached) that does this. It starts a master SSH daemon for the connection if needed. Then it exec()s SSH. Just put it in your path and use perssh instead of ssh. It has some

...ting the connections and invoking 'sshd -i' with them, like inetd does. In later patches I'll extend sshd to listen on a Bluetooth socket (and advertise the service in SDP) for itself, and extend the ssh client to make the connection directly. For now, I'm testing with http://david.woodhou.se/btserv.c and ssh -o 'ProxyCommand socat stdio SOCKET-CONNECT:31:3:x1ec1e4e21f000100' root at bluetooth Index: canohost.c =================================================================== RCS file: /cvs/openssh/canohost.c,v retrieving revision 1.75 diff -u -p -r1.75 canohost.c --- cano...

Three patches attached. One implements a 'ControlPersist' option, which when used with 'ControlMaster auto' or 'ControlMaster 'yes' make makes the master background itself and stick around after its own primary session is completed. The second causes control clients to pass X11 display, auth proto and auth data over the control socket so that appropriate X11
