...ong" (or so). I think this is a bug in the - commercial and expensive - compiler. I didn't try gcc on that platform, yet. No, I didn't try 0.9.6, yet. 2. scp will hang after the file transfer(s) The "fix" is to change the line 495 in serverloop.c from shutdown(fdin, SHUT_WR); to shutdown(fdin, SHUT_RDWR); The same which I did in 2.1.1. 3. X11 forwarding does just work for standard X clients - if you configure it with --with-ipaddr-display - but not for all X applications. The reason is that Siemens is using a named pipe in /tmp/.X11-unix for X communicati...

On a non-trusted system with HP AnsiC it seems to work if changing shutdown(fdin, SHUT_WR) to shutdown(fdin, SHUT_RDWR) in serverloop.c (lines 320 & 464) On a trusted system with gcc however this does not seem to have any effect. Here I use #define USE_PIPES 1 in includes.h as workaround I think I will have to do some more checks with compilers/(non-)trusted systems... Or any ot...

...race, or else determine that I also need to augment the loop condition in the reader thread to additionally break out of the loop when the pipe-to-self sees EOF even when nbd_aio_is_dead() has not yet been satisfied I'm also fairly confident that I'll need to patch libnbd to call shutdown(SHUT_WR) on plaintext and gnutls_bye(GNUTLS_SHUT_WR) on TLS connections after sending NBD_CMD_DISC, as that is something we lowt when the nbd plugin switched to libnbd, even after documenting in commit 430f8141 why it is important for preventing shutdown deadlocks.

...one or both directions of traffic are no longer needed, making this asynchronous handling in close() much faster. At least nbdkit is known to react favorably to a shutdown() request - see nbdkit commit 430f8141. We may want to add h->sock->ops->shutdown() (especially if we want to handle SHUT_WR through adding more states for more graceful shutdown paths, including when TLS is involved), but even in the short-term, something as simple as adding shutdown(h->fd, SHUT_RDWR) immediately before the s->sock->ops->close() would be helpful. That said, I think we want a two-pronged app...
