2018-05-07net: nixge: Fix error path for obtaining mac addressMoritz Fischer
Fix issue where nixge_get_nvmem_address() returns a non-NULL return value on a failed nvmem_cell_get() that causes an invalid access when error value encoded in pointer is dereferenced. Furthermore ensure that buffer allocated by nvmem_cell_read() actually gets kfreed() if the function succeeds.

2018-05-07net: 3com: 3c59x: irq save variant of ISRAnna-Maria Gleixner
When vortex_boomerang_interrupt() is invoked from vortex_tx_timeout() or poll_vortex() interrupts must be disabled. This detaches the interrupt disable logic from locking which requires patching for PREEMPT_RT. The advantage of avoiding spin_lock_irqsave() in the interrupt handler is minimal, but converting it removes all the extra code for callers which come not from interrupt context.

Locking is done in the same way in _vortex_interrupt() and _boomerang_interrupt(). To prevent duplication, move the locking into the calling vortex_boomerang_interrupt() function.

This means that any pointer derived from it needs to be adjusted. The only value that this applies to is the vcpu_info pointer for VCPU 0. For PV and HVM with the callback vector feature, this gets done via the smp_ops prepare_boot_cpu callback. Older Xen versions do not support the HVM callback vector, so there is no Xen-specific smp_ops set up in that scenario. So, the vcpu_info pointer for VCPU 0 never gets set to the proper value, and the first reference of it will be bad. Fix this by resetting it immediately after the remap.

Clear the old_state and new_state pointers for every object in drm_atomic_state_default_clear(). Otherwise drm_atomic_get_{new,old}_*_state() will hand out stale pointers to anyone who hasn't first confirmed that the object is in fact part of the current atomic transcation, if they are called after we've done the ww backoff dance while hanging on to the same drm_atomic_state. For example, handle_conflicting_encoders() looks like it could hit this since it iterates the full connector list and just calls drm_atomic_get_new_connector_state() for each. And I believe we have now witnessed this happening at least once in i915 check_digital_port_conflicts(). Commit 8b69449d2663 ("drm/i915: Remove last references to drm_atomic_get_existing* macros") changed the safe drm_atomic_get_existing_connector_state() to the unsafe drm_atomic_get_new_connector_state(), which opened the doors for this particular bug there as well. v2: Split private objs out to a separate patch (Daniel) Cc: stable@vger.kernel.org Cc: Maarten Lankhorst <maarten.lankhorst@linux.intel.com> Cc: Laurent Pinchart <laurent.pinchart@ideasonboard.com> Cc: Abhay Kumar <abhay.kumar@intel.com> Fixes: 581e49fe6b41 ("drm/atomic: Add new iterators over all state, v3.")

IPCTNL_MSG_CT_GET_STATS netlink command allow to monitor current number of conntrack entries. However, if one wants to compare it with the maximum (and detect exhaustion), the only solution is currently to read sysctl value. This patch add nf_conntrack_max value in netlink message, and simplify monitoring for application built on netlink API.

2018-05-06netfilter: ip6t_srh: extend SRH matching for previous, next and last SIDAhmed Abdelsalam
IPv6 Segment Routing Header (SRH) contains a list of SIDs to be crossed by SR encapsulated packet. Each SID is encoded as an IPv6 prefix. When a Firewall receives an SR encapsulated packet, it should be able to identify which node previously processed the packet (previous SID), which node is going to process the packet next (next SID), and which node is the last to process the packet (last SID) which represent the final destination of the packet in case of inline SR mode. An example use-case of using these features could be SID list that includes two firewalls. When the second firewall receives a packet, it can check whether the packet has been processed by the first firewall or not. Based on that check, it decides to apply all rules, apply just subset of the rules, or totally skip all rules and forward the packet to the next SID. This patch extends SRH match to support matching previous SID, next SID, and last SID. Signed-off-by: Ahmed Abdelsalam <amsalam20@gmail.com> Signed-off-by: Pablo Neira Ayuso <pablo@netfilter.org>
2018-05-06netfilter: nft_numgen: enable hashing of one elementLaura Garcia Liebana
The modulus in the hash function was limited to > 1 as initially there was no sense to create a hashing of just one element. Nevertheless, there are certain cases specially for load balancing where this case needs to be addressed. This patch fixes the following error. Error: Could not process rule: Numerical result out of range add rule ip nftlb lb01 dnat to jhash ip saddr mod 1 map { 0: 192.168.0.10 } ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^ The solution comes to force the hash to 0 when the modulus is 1.

2018-05-06netfilter: nft_numgen: add map lookups for numgen statementsLaura Garcia Liebana
This patch includes a new attribute in the numgen structure to allow the lookup of an element based on the number generator as a key. For this purpose, different ops have been included to extend the current numgen inc functions. Currently, only supported for numgen incremental operations, but it will be supported for random in a follow-up patch.

2018-05-05KVM: x86: remove APIC Timer periodic/oneshot spikesAnthoine Bourgeois
Since the commit "8003c9ae204e: add APIC Timer periodic/oneshot mode VMX preemption timer support", a Windows 10 guest has some erratic timer spikes. Here the results on a 150000 times 1ms timer without any load: Before 8003c9ae204e | After 8003c9ae204e Max 1834us | 86000us Mean 1100us | 1021us Deviation 59us | 149us Here the results on a 150000 times 1ms timer with a cpu-z stress test: Before 8003c9ae204e | After 8003c9ae204e Max 32000us | 140000us Mean 1006us | 1997us Deviation 140us | 11095us The root cause of the problem is starting hrtimer with an expiry time already in the past can take more than 20 milliseconds to trigger the timer function. It can be solved by forward such past timers immediately, rather than submitting them to hrtimer_start(). In case the timer is periodic, update the target expiration and call hrtimer_start with it. v2: Check if the tsc deadline is already expired. Thank you Mika. v3: Execute the past timers immediately rather than submitting them to hrtimer_start(). v4: Rearm the periodic timer with advance_periodic_target_expiration() a simpler version of set_target_expiration(). Thank you Paolo.
