2015-06-02vfs: read file_handle only once in handle_to_pathSasha Levin
We used to read file_handle twice. Once to get the amount of extra bytes, and once to fetch the entire structure. This may be problematic since we do size verifications only after the first read, so if the number of extra bytes changes in userspace between the first and second calls, we'll have an incoherent view of file_handle. Instead, read the constant size once, and copy that over to the final structure without having to re-read it again.

2015-06-02lib: Fix strnlen_user() to not touch memory after specified maximumJan Kara
If the specified maximum length of the string is a multiple of unsigned long, we would load one long behind the specified maximum. If that happens to be in a next page, we can hit a page fault although we were not expected to. Fix the off-by-one bug in the test whether we are at the end of the specified range.

cpumask_test_cpu() doesn't take volatile, unlike the obsoleted cpu_isset. The only place ia64 really cares is the spin waiting for a bit; udelay() is probably a barrier but insert barrier() to be sure.

We currently rely on the PMTU discovery of xfrm. However if a packet is localy sent, the PMTU mechanism of xfrm tries to to local socket notification what might not work for applications like ping that don't check for this. So add pmtu handling to vti6_xmit to report MTU changes immediately.

This reverts commit f96dee13b8e10f00840124255bed1d8b4c6afd6f. It isn't right, ethtool is meant to manage one PHY instance per netdevice at a time, and this is selected by the SET command. Therefore by definition the GET command must only return the settings for the configured and selected PHY. Reported-by: Ben Hutchings <ben@decadent.org.uk> Signed-off-by: David S.

2015-06-01bnx2x: Move statistics implementation into semaphoresYuval Mintz
Commit dff173de84958 ("bnx2x: Fix statistics locking scheme") changed the bnx2x locking around statistics state into using a mutex - but the lock is being accessed via a timer which is forbidden. [If compiled with CONFIG_DEBUG_MUTEXES, logs show a warning about accessing the mutex in interrupt context] This moves the implementation into using a semaphore [with size '1'] instead.

2015-06-01xen: netback: read hotplug script once at start of day.Ian Campbell
When we come to tear things down in netback_remove() and generate the uevent it is possible that the xenstore directory has already been removed (details below). In such cases netback_uevent() won't be able to read the hotplug script and will write a xenstore error node. A recent change to the hypervisor exposed this race such that we now sometimes lose it (where apparently we didn't ever before). Instead read the hotplug script configuration during setup and use it for the lifetime of the backend device. The apparently more obvious fix of moving the transition to state=Closed in netback_remove() to after the uevent does not work because it is possible that we are already in state=Closed (in reaction to the guest having disconnected as it shutdown). Being already in Closed means the toolstack is at liberty to start tearing down the xenstore directories. In principal it might be possible to arrange to unregister the device sooner (e.g on transition to Closing) such that xenstore would still be there but this state machine is fragile and prone to anger... A modern Xen system only relies on the hotplug uevent for driver domains, when the backend is in the same domain as the toolstack it will run the necessary setup/teardown directly in the correct sequence wrt xenstore changes.
