[Pkg-vsquare-devel] Bug#484265: vde_plug does not connect to socket

[martin f krafft]

Package: vde2
Version: 2.2.0-pre2-1
Severity: normal
File: /usr/bin/vde_plug

There's some weird stuff happening in vde_plug: I have a vde_switch
started with ctlsock directory in ./vde0, and now I am trying to
plug into it:

+lapse:~|master|.tmp/testnet.k13727% ls vde0                              #1839
ctl  vde_switch.pid
+lapse:~|master|.tmp/testnet.k13727% strace -f vde_plug vde0/ctl          #1840
[...]
connect(5, {sa_family=AF_FILE, path="vde0/ctl/ctl"}, 110) = -1 ENOTDIR (Not a directory)
[...]
send(5, "\316\372\355\376\3\0\0\0\0\0\0\0\1\0vde0/ctl.14357-000"..., 183, 0) = -1 ENOTCONN (Transport endpoint is not connected)

Note how the manpage says control socket path, and yet the connect()
seems to take it as directory. And even though the
vde0/ctl.14357-000 control socket gets created (it now exists and is
never removed), the send() fails.

Full vde_plug.strace attached.

Let's see what happens if we pass the directory instead of the
socket path.

+lapse:~|master|.tmp/testnet.k13727% strace -f vde_plug vde0              #1841
[...]
connect(5, {sa_family=AF_FILE, path="vde0/ctl"}, 110) = 0
bind(6, {sa_family=AF_FILE, path="vde0.14393-00000"}, 110) = 0
[...]
chmod("", 0700)                         = -1 ENOENT (No such file or directory)

There's stuff broken here too, the chmod doesn't get a proper path.
Also, if I pass ./vde0/, the connect() uses ./vde0//ctl and the bind
then tries ./vde0/.14393-00000.

Full vde_plug.strace2 attached.

This all makes me think that there's a need for some time with the
code...
