The rules for configuring the password are equivalent of those used
for HVM, but the actual guest config option is a little different as a
result of the recent refactoring of the PVFB config file syntax.
- If the 'vfb' option in the guest config has a 'vncpasswd' parameter
specified
- If the passwd is not zero length, use that
- Else run with no authentication (important as it enables
override of next rule)
- Else-if the xend-config.sxp has a password specified use that
- Else run with no authentication
Example configuration:
- To set an explicit guest password:
vfb = [ "type=vnc,vncunused=1,vnclisten=0.0.0.0,vncpasswd=123456"]
- To disable authentication, overriding any XenD configured
default password
vfb = [ "type=vnc,vncunused=1,vnclisten=0.0.0.0,vncpasswd="]
- To run with default XenD configured password (if any)
vfb = [ "type=vnc,vncunused=1,vnclisten=0.0.0.0"]

Changeset 13018:c98ca86138a7422cdf9b15d87c95619b7277bb6a merely sweeps
the bug under the carpet: it silences zap_page_range()'s cries for
help by keeping interrupts enabled. That doesn't fix the bug, and
it's also wrong: if a critical region gets interrupted, and the
interrupt printk()s, xenfb_refresh() gets executed and promptly
deadlocks.
This patch fixes the locking, but leaves open a race between
xenfb_update_screen() and do_no_page(). See the source code for a
detailed explanation of how it works, and where it fails.

On the c-bindings side the marshalling code converts the string representation to an enum value. A subsequent attempt to convert the enum from a string to an enum was causing a seg fault.

skb_segment fails to segment linear packets correctly because it
tries to write all linear parts of the original skb into each
segment. This will always panic as each segment only contains
enough space for one MSS.
This was not detected earlier because linear packets should be
rare for GSO. In fact it still remains to be seen what exactly
created the linear packets that triggered this bug. Basically
the only time this should happen is if someone enables GSO
emulation on an interface that does not support SG.
