Hi, if socketpair support has been compiled in but the host where rsync is run doesn't support it, you get error pipe failed in do_recv This patch makes rsync use pipe if socketpair fails. Yours, Harri J?rvi CC me if you reply to this thread since I'm not on the mailing list -------------- next part -----...

Does anyone actually use sshd on a system that doesn't have socketpair? It's used elsewhere so the don't-have path seems like it'd never be exercised these days.

...nnot copy data to rsync volumes with option 'use chroot'; I get the following messages on the client: pipe failed in do_recv rsync error: error in socket IO (code 10) at main.c(375) rsync: connection unexpectedly closed (69 bytes read so far) What seems to occur on the server is that socketpair(3) (not pipe(2)) is called, which needs to open /dev/ticotsord. Since I do not have a /dev in the chroot directory, this call fails. Disabling HAVE_SOCKETPAIR in config.h seems to resolve the problem. Is there any way this can be worked around more appropriately (perhaps by calling socketpair() be...

...latest rsync (3.0.7-1) under an up-to-date cygwin on Windows 7 x64 gets into some kind of busy wait situation when transferring large files over ssh. rsync, ssh, and zip can all be consuming much cpu time. I downloaded and built rsync 3.0.7 locally, manually editing config.status to turn off HAVE_SOCKETPAIR. The resulting rsync works fine. So, what specific diagnosis and further information would you find most helpful? A few months ago, Corinna and I went through a whole round of trying to get socketpair to work better, and she developed a BLODA work-around. At her request, I have kept the particular...

...c over ssh freezing during a large transfer (typically several GB). I have now gotten to the bottom of these problems, and have written a small test program which demonstrates a deadlock in sshd when doing large bi-directional transfers. Luckily the problem is easily solved by modifying sshd to use socketpair() instead of pipe(). Just remove "#define USE_PIPES 1" from near the bottom of includes.h does the trick. The test program, along with instructions for use and an explanation of some of the pipe() bugs in various OSes that make this change necessary is available from ftp://samba.org/pub/...

Hi, This diff (for portable) makes the chrooted preauth privsep process log via the monitor using a shared socketpair. It removes the need for /dev/log inside /var/empty and makes mandatory sandboxing of the privsep child easier down the road (no more socket() syscall required).
