libxc: provide notification of final checkpoint to restore end
When the restore code sees this notification it will restore the
currently in-progress checkpoint when it completes.
This allows the restore end to finish up without waiting for a
spurious timeout on the receive fd and thereby avoids unnecessary
error logging in the case of a successful migration or restore.
In the normal migration or restore case the first checkpoint is always
the last. For a rolling checkpoint (such as Remus) the notification is
currently unused but could be used in the future for example to
provide a controlled failover for reasons other than error

tools/xenstore: correctly handle errors from read_message
The return value of read_message needs to be checked in order to avoid
waiting forever for a message if there is an error on the communication
channel with xenstore. Currently, this is only checked if USE_PTHREAD is
defined (by checking for read thread exit), and that path is prone to
deadlock if request_mutex is held while waiting.
Since the failure of read_message leaves the socket in an undefined
state, close the socket and force all threads waiting on a read to return.
This also fixes xs_read_watch in the case where a read thread is not

populate-on-demand guests, this manifests as a guest crash when one

and ept_get_entry returns p2m_mmio_dm.
This bug can also be fixed by making both ept_set_entry and

xl: treat sub-command main function like a regular C main() function
Currently xl passes the entire argc+argv to each subcommand and relies
on the preservation of the global optind variable to ensure that the
subcommand correctly handles argument parsing (e.g. accounting for "xl
[command]" vs "xl -v [command]").
This requirement for individual sub-commands to parse arguments
relative to optind is subtle and prone to being forgotten (or simply
not expected). Several sub-commands have recently been broken in this
way (now fixed).
Therefore arrange that the argv+argc passed to the sub-commands looks
like you would expect for a regular C main function and includes
argv[0] equal to the command name with command specific arguments in
argv[1] onwards.
Since all sub-commands (currently) correctly obey the optind it is
sufficient to reset it to 1 (as described in getopt(3)) in order to
not break the sub-commands' own argument parsing.

XL sub-commands are expected to parse their arguments relative to the

Not all commands do this and they are therefore broken if the user
uses "xl -v command", correct such problems

functions will free only the members of a type recursively but will
not free the actual type structure itself. The allocation of the type

e.g. lists/arrays of types or embedded in other structures etc.
The exceptions to this rule are libxl_string_list_destroy and
libxl_key_value_list_destroy but I'm not 100% convinced they are
exceptions (since they are kind-of opaque) and I couldn't see a

The per-thread hypercall buffer is usually cleaned up on pthread_exit

This frees the data for the current thread only but that is OK since
any other threads will be cleaned up by the destructor.

* Ensure hcall_buf_pkey is initialised before use. Thanks to
Christoph Egger for his help diagnosing this issue on NetBSD.
