2019-04-08ipv4: Prepare fib_config for IPv6 gatewayDavid Ahern
Similar to rtable, fib_config needs to allow the gateway to be either an IPv4 or an IPv6 address. To that end, rename fc_gw to fc_gw4 to mean an IPv4 address and add fc_gw_family. Checks on 'is a gateway set' are changed to see if fc_gw_family is set. In the process prepare the code for a fc_gw_family == AF_INET6.

2019-04-08ipv4: Prepare rtable for IPv6 gatewayDavid Ahern
To allow the gateway to be either an IPv4 or IPv6 address, remove rt_uses_gateway from rtable and replace with rt_gw_family. If rt_gw_family is set it implies rt_uses_gateway. Rename rt_gateway to rt_gw4 to represent the IPv4 version. Signed-off-by: David Ahern <dsahern@gmail.com> Reviewed-by: Ido Schimmel <idosch@mellanox.com> Signed-off-by: David S.

2019-04-08net: Replace nhc_has_gw with nhc_gw_familyDavid Ahern
Allow the gateway in a fib_nh_common to be from a different address family than the outer fib{6}_nh. To that end, replace nhc_has_gw with nhc_gw_family and update users of nhc_has_gw to check nhc_gw_family. Now nhc_family is used to know if the nh_common is part of a fib_nh or fib6_nh (used for container_of to get to route family specific data), and nhc_gw_family represents the address family for the gateway.

2019-04-08r8169: disable ASPM againHeiner Kallweit
There's a significant number of reports that re-enabling ASPM causes different issues, ranging from decreased performance to system not booting at all. This affects only a minority of users, but the number of affected users is big enough that we better switch off ASPM again. This will hurt notebook users who are not affected by the issues, they may see decreased battery runtime w/o ASPM. With the PCI core folks is being discussed to add generic sysfs attributes to control ASPM. Once this is in place brave enough users can re-enable ASPM on their system.

2019-04-07net: vrf: Fix ping failed when vrf mtu is set to 0Miaohe Lin
When the mtu of a vrf device is set to 0, it would cause ping failed. So I think we should limit vrf mtu in a reasonable range to solve this problem. I set dev->min_mtu to IPV6_MIN_MTU, so it will works for both ipv4 and ipv6. And if dev->max_mtu still be 0 can be confusing, so I set dev->max_mtu to ETH_MAX_MTU.

2019-04-07net: sched: flower: insert filter to ht before offloading it to hwVlad Buslov
John reports: Recent refactoring of fl_change aims to use the classifier spinlock to avoid the need for rtnl lock. In doing so, the fl_hw_replace_filer() function was moved to before the lock is taken. This can create problems for drivers if duplicate filters are created (commmon in ovs tc offload due to filters being triggered by user-space matches). Drivers registered for such filters will now receive multiple copies of the same rule, each with a different cookie value. This means that the drivers would need to do a full match field lookup to determine duplicates, repeating work that will happen in flower __fl_lookup(). Currently, drivers do not expect to receive duplicate filters. To fix this, verify that filter with same key is not present in flower classifier hash table and insert the new filter to the flower hash table before offloading it to hardware. Implement helper function fl_ht_insert_unique() to atomically verify/insert a filter. This change makes filter visible to fast path at the beginning of fl_change() function, which means it can no longer be freed directly in case of error. Refactor fl_change() error handling code to deallocate the filter with rcu timeout.

This: reduces memory usage results in slightly fewer memory accesses slightly improves parallelism makes a configuration option unnecessary The main change from previous version is to use a distinct type for the pointer in the bucket which has a bit-lock in it.

2019-04-07rhashtable: add lockdep tracking to bucket bit-spin-locks.NeilBrown
Native bit_spin_locks are not tracked by lockdep. The bit_spin_locks used for rhashtable buckets are local to the rhashtable implementation, so there is little opportunity for the sort of misuse that lockdep might detect. However locks are held while a hash function or compare function is called, and if one of these took a lock, a misbehaviour is possible. As it is quite easy to add lockdep support this unlikely possibility seems to be enough justification. So create a lockdep class for bucket bit_spin_lock and attach through a lockdep_map in each bucket_table. Without the 'nested' annotation in rhashtable_rehash_one(), lockdep correctly reports a possible problem as this lock is taken while another bucket lock (in another table) is held. This confirms that the added support works. With the correct nested annotation in place, lockdep reports no problems. Signed-off-by: NeilBrown <neilb@suse.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2019-04-07rhashtable: use bit_spin_locks to protect hash bucket.NeilBrown
This patch changes rhashtables to use a bit_spin_lock on BIT(1) of the bucket pointer to lock the hash chain for that bucket. The benefits of a bit spin_lock are: - no need to allocate a separate array of locks. - no need to have a configuration option to guide the choice of the size of this array - locking cost is often a single test-and-set in a cache line that will have to be loaded anyway. When inserting at, or removing from, the head of the chain, the unlock is free - writing the new address in the bucket head implicitly clears the lock bit. For __rhashtable_insert_fast() we ensure this always happens when adding a new key. - even when lockings costs 2 updates (lock and unlock), they are in a cacheline that needs to be read anyway. The cost of using a bit spin_lock is a little bit of code complexity, which I think is quite manageable. Bit spin_locks are sometimes inappropriate because they are not fair - if multiple CPUs repeatedly contend of the same lock, one CPU can easily be starved. This is not a credible situation with rhashtable. Multiple CPUs may want to repeatedly add or remove objects, but they will typically do so at different buckets, so they will attempt to acquire different locks. As we have more bit-locks than we previously had spinlocks (by at least a factor of two) we can expect slightly less contention to go with the slightly better cache behavior and reduced memory consumption. To enhance type checking, a new struct is introduced to represent the pointer plus lock-bit that is stored in the bucket-table. This is "struct rhash_lock_head" and is empty. A pointer to this needs to be cast to either an unsigned lock, or a "struct rhash_head *" to be useful. Variables of this type are most often called "bkt". Previously "pprev" would sometimes point to a bucket, and sometimes a ->next pointer in an rhash_head. As these are now different types, pprev is NULL when it would have pointed to the bucket. In that case, 'blk' is used, together with correct locking protocol. Signed-off-by: NeilBrown <neilb@suse.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2019-04-07rhashtable: allow rht_bucket_var to return NULL.NeilBrown
Rather than returning a pointer to a static nulls, rht_bucket_var() now returns NULL if the bucket doesn't exist. This will make the next patch, which stores a bitlock in the bucket pointer, somewhat cleaner. This change involves introducing __rht_bucket_nested() which is like rht_bucket_nested(), but doesn't provide the static nulls, and changing rht_bucket_nested() to call this and possible provide a static nulls - as is still needed for the non-var case.

2019-04-07rhashtable: use cmpxchg() in nested_table_alloc()NeilBrown
nested_table_alloc() relies on the fact that there is at most one spinlock allocated for every slot in the top level nested table, so it is not possible for two threads to try to allocate the same table at the same time. This assumption is a little fragile (it is not explicit) and is unnecessary as cmpxchg() can be used instead. A future patch will replace the spinlocks by per-bucket bitlocks, and then we won't be able to protect the slot pointer with a spinlock. So replace rcu_assign_pointer() with cmpxchg() - which has equivalent barrier properties. If it the cmp fails, free the table that was just allocated.

2019-04-07dt-bindings: cpu: Fix JSON schemaMaxime Ripard
Commit fd73403a4862 ("dt-bindings: arm: Add SMP enable-method for Milbeaut") added support for a new cpu enable-method, but did so using tabulations to ident. This is however invalid in the syntax, and resulted in a failure when trying to use that schemas for validation. Use spaces instead of tabs to indent to fix this.

vsprintf() in __base_pr() uses nonliteral format string and it breaks compilation for those who provide corresponding extra CFLAGS, e.g.: https://github.com/libbpf/libbpf/issues/27 If libbpf is built with the flags from PR: libbpf.c:68:26: error: format string is not a string literal [-Werror,-Wformat-nonliteral] return vfprintf(stderr, format, args); ^~~~~~ 1 error generated.

2019-04-06net: hsr: Fix node prune function for forget time expiryAaron Kramer
HSR should forget nodes after configured node forget time expiry based on HSR_NODE_FORGET_TIME. As part of hsr_prune_nodes(), code checks to see if entries are to be flushed out if not heard for longer than forget time. But currently hsr_prune_nodes() is called only once during device creation. Restart the timer at the end of hsr_prune_nodes() so that hsr_prune_nodes() gets called periodically and forgotten entries are removed from node table.
