* fix typo/thinko in get_random_bytes()Luck, Tony2011-11-171-1/+1
| | | | | | | | | | | | If there is an architecture-specific random number generator we use it to acquire randomness one "long" at a time. We should put these random words into consecutive words in the result buffer - not just overwrite the first word again and again. Signed-off-by: Tony Luck <tony.luck@intel.com> Acked-by: H.

Turns out that tty_open fails, because the hvc_alloc was not yet done. In former times this could not happen, since the probe function automatically called hvc_alloc. With newer versions (multiport) some host<->guest interaction is required before hvc_alloc is called. This might be too late, especially if an initramfs is involved. Lets use a completion if we have multiport and an early console.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This commit adds port-specific stats for the number of bytes received, sent and discarded. They're exposed via the debugfs interface. This data can be used to check for data loss bugs (or disprove such claims). It can also be used for accounting, if there's such a need. The stats remain valid throughout the lifetime of the port. Unplugging a port will reset the stats. The numbers are not reset across port opens/closes.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Instead of pulling in a buffer from the vq each time it's called, get_inbuf() now checks if the current active buffer, in port->inbuf is valid. If it is, just returns a pointer to it. This ends up simplifying a lot of code calling get_inbuf() since the check for port->inbuf being valid was done by all the callers.

So any requests by the host to change the name are ignored. Before this patch, if the hypervisor sent a port name while we had one set already, we would leak memory equivalent to the size of the old name. This scenario wasn't expected so far, but with the suspend-resume support, we'll send the VIRTIO_CONSOLE_PORT_READY message after restore, which can get us into this situation.

Fix up conflicts in arch/x86/kernel/kprobes.c manually. Ingo's tree did the insane "add volatile to const array", which just doesn't make sense ("volatile const"?). But we could remove the const *and* make the array volatile to make doubly sure that gcc doesn't optimize it away.. Also fix up kernel/trace/ring_buffer.c non-data-conflicts manually: the reader_lock has been turned into a raw lock by the core locking merge, and there was a new user of it introduced in this perf core merge. Make sure that new use also uses the raw accessor functions.

Most of it is straight forward conversion. A couple of places needed some tweaking like kgdb which separates the debug notifier from the nmi handler and mce removes a call to notify_die. [Thanks to Ying for finding out the history behind that mce call https://lkml.org/lkml/2010/5/27/114 And Boris responding that he would like to remove that call because of it https://lkml.org/lkml/2011/9/21/163] The things that get converted are the registeration/unregistration routines and the nmi handler itself has its args changed along with code removal to check which list it is on (most are on one NMI list except for kgdb which has both an NMI routine and an NMI Unknown routine).

Use wait_event_freezable() instead. The only annoyance is that wait_event_freezable() wakes up with -ERESTART if there are pending signals while apm_ioctl() wants to ignore all signals until suspend is complete. We can play with @current->[real_]blocked but this is hardly a performance or latency critical path - simply chill a bit on each iteration until SUSPEND_DONE for unlikely cases where there are pending signals.

[The first hunk didn't make sense given one could expect way less data than TPM_BUFSIZE, so added tpm_transmit boundary check over bufsiz instead The last parameter of tpm_transmit() reflects the amount of data expected from the device, and not the buffer size being supplied to it.
