similar to: [PATCH][RFC] permit domU userspace to watch xenstore

Dear xen-devel, There''s a race condition in xenfs (xenstore driver) that causes userspace utility xenstore-watch to crash. Normally, the userspace process gets an "OK" from xenfs and then the watch fires immediately after. Occasionally, this happens the other way around: the watch fires before the driver sends "OK", which confuses the xenstore-watch client. It seems

This change adds the ability to group entries in a string list with single quotes. So the string: "'foo bar'" becomes 1 token rather than 2. Consequently single quotes must now be escaped: "\'" resolves to a literal single quote. Incidentally, this change also alters another, probably unintentional behaviour of the previous implementation, in that tokens are

Hi all, I think this is a serious bug, existing in the pvops 2.6.31.13 (also existing in linux 2.6.35); In the xenbus driver (drivers/xen/xenfs/xenbus.c), the function of xenbus_file_read has a section of source code like this: if (ret != sz) { if (i == 0) i = -EFAULT; goto out; } /* Clear

Hi, Anybody (Christian?) could please tell me if we can get the support for registering watch with /proc/xen/xenbus? (..OK, I know that we will change it this /proc stuff to a device soon) So far we can only do read/write/rm. I really miss the xen watch feature.

So far only the watch path was checked to be zero terminated, while the watch token was merely assumed to be. Additionally, none of the three associated memory allocations got checked for being successful.
