[Xen-devel] xenstore xenbus failure

[Adam Wendt <thelsdj@xxxxxxxxx>]

Hi,

Still having problems getting xenstore working without the socket interface. Here is output running simple xenstore-ls:

Got message DIRECTORY len 2 from 0x1451b80
Writing msg DIRECTORY (tool) out to 0x1451b80
xenstore-ls: xs_directory (/): Invalid argument
IN 0x1451b80 20090120 10:43:23 DIRECTORY (/ )
OUT 0x1451b80 20090120 10:43:23 DIRECTORY (tool vm local )

First 2 lines are verbose output of xenstored, middle line is output of the xenstore client and last 2 lines are trace log from xenstored.

'Invalid argument' seems to be coming from the write() call on line 98 of xs_lib.c.

Seems to happen the _second_ time that xs_write_all is called from xs_talkv (writing the parameters) in this case the "/" for the ls.

From the output above we can see that xenstored is receiving the write, and even the "/" parameter, so why would the write be failing with 'Invalid argument'?

Thanks,

Adam
