2017-11-30xfrm: Stop using dst->next in bundle construction.David Miller
While building ipsec bundles, blocks of xfrm dsts are linked together using dst->next from bottom to the top. The only thing this is used for is initializing the pmtu values of the xfrm stack, and for updating the mtu values at xfrm_bundle_ok() time. The bundle pmtu entries must be processed in this order so that pmtu values lower in the stack of routes can propagate up to the higher ones. Avoid using dst->next by simply maintaining an array of dst pointers as we already do for the xfrm_state objects when building the bundle. Signed-off-by: David S.

2017-11-30net: Rearrange dst_entry layout to avoid useless padding.David Miller
We have padding to try and align the refcount on a separate cache line. But after several simplifications the padding has increased substantially. So now it's easy to change the layout to get rid of the padding entirely. We group the write-heavy __refcnt and __use with less often used items such as the rcu_head and the error code.

2017-11-30xfrm: Move dst->path into struct xfrm_dstDavid Miller
The first member of an IPSEC route bundle chain sets it's dst->path to the underlying ipv4/ipv6 route that carries the bundle. Stated another way, if one were to follow the xfrm_dst->child chain of the bundle, the final non-NULL pointer would be the path and point to either an ipv4 or an ipv6 route. This is largely used to make sure that PMTU events propagate down to the correct ipv4 or ipv6 route. When we don't have the top of an IPSEC bundle 'dst->path == dst'. Move it down into xfrm_dst and key off of dst->xfrm. Signed-off-by: David S. Miller <davem@davemloft.net> Reviewed-by: Eric Dumazet <edumazet@google.com>
2017-11-30ipv6: Move dst->from into struct rt6_info.David Miller
The dst->from value is only used by ipv6 routes to track where a route "came from". Any time we clone or copy a core ipv6 route in the ipv6 routing tables, we have the copy/clone's ->from point to the base route. This is used to handle route expiration properly. Only ipv6 uses this mechanism, and only ipv6 code references it. So it is safe to move it into rt6_info. Signed-off-by: David S.

2017-11-30xfrm: Move child route linkage into xfrm_dst.David Miller
XFRM bundle child chains look like this: xdst1 --> xdst2 --> xdst3 --> path_dst All of xdstN are xfrm_dst objects and xdst->u.dst.xfrm is non-NULL. The final child pointer in the chain, here called 'path_dst', is some other kind of route such as an ipv4 or ipv6 one. The xfrm output path pops routes, one at a time, via the child pointer, until we hit one which has a dst->xfrm pointer which is NULL. We can easily preserve the above mechanisms with child sitting only in the xfrm_dst structure. All children in the chain before we break out of the xfrm_output() loop have dst->xfrm non-NULL and are therefore xfrm_dst objects. Since we break out of the loop when we find dst->xfrm NULL, we will not try to dereference 'dst' as if it were an xfrm_dst. Signed-off-by: David S. Miller <davem@davemloft.net>

net/atm/mpoa_* files use 'struct timeval' to store event timestamps. struct timeval uses a 32-bit seconds field which will overflow in the year 2038 and beyond. Morever, the timestamps are being compared only to get seconds elapsed, so struct timeval which stores a seconds and microseconds field is an overkill.

2017-11-29vsprintf: don't use 'restricted_pointer()' when not restrictingLinus Torvalds
Instead, just fall back on the new '%p' behavior which hashes the pointer. Otherwise, '%pK' - that was intended to mark a pointer as restricted - just ends up leaking pointers that a normal '%p' wouldn't leak. Which just make the whole thing pointless. I suspect we should actually get rid of '%pK' entirely, and make it just work as '%p' regardless, but this is the minimal obvious fix. People who actually use 'kptr_restrict' should weigh in on which behavior they want.

Pull printk pointer hashing update from Tobin Harding: "Here is the patch set that implements hashing of printk specifier %p. First we have two clean up patches then we do the hashing. Hashing is done via the SipHash algorithm. The next patch adds printk specifier %px for printing pointers when we _really_ want to see the address i.e %px is functionally equivalent to %lx. Final patch in the set fixes KASAN since we break it by hashing %p. For the record here is the justification for the series: Currently there exist approximately 14 000 places in the Kernel where addresses are being printed using an unadorned %p. This potentially leaks sensitive information about the Kernel layout in memory. Many of these calls are stale, instead of fixing every call we hash the address by default before printing. We then add %px to provide a way to print the actual address. Although this is achievable using %lx, using %px will assist us if we ever want to change pointer printing behaviour. %px is more uniquely grep'able (there are already >50 000 uses of %lx). The added advantage of hashing %p is that security is now opt-out, if you _really_ want the address you have to work a little harder and use %px. This will of course break some users, forcing code printing needed addresses to be updated" [ I do expect this to be an annoyance, and a number of %px users to be added for debuggability. But nobody is willing to audit existing %p users for information leaks, and a number of places really only use the pointer as an object identifier rather than really 'I need the address'.

Don't use %x and casting to print out a kernel address, instead use the %pK and remove the casting.

2017-11-28vxlan: use __be32 type for the param vni in __vxlan_fdb_deleteXin Long
All callers of __vxlan_fdb_delete pass vni with __be32 type, and this param should be declared as __be32 type. Fixes: 3ad7a4b141eb ("vxlan: support fdb and learning in COLLECT_METADATA mode") Signed-off-by: Xin Long <lucien.xin@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2017-11-28bonding: use nla_get_u64 to extract the value for IFLA_BOND_AD_ACTOR_SYSTEMXin Long
bond_opt_initval expects a u64 type param, it's better to use nla_get_u64 to extract the value here, to eliminate a sparse endianness mismatch warning.

2017-11-28sctp: use right member as the param of list_for_each_entryXin Long
Commit d04adf1b3551 ("sctp: reset owner sk for data chunks on out queues when migrating a sock") made a mistake that using 'list' as the param of list_for_each_entry to traverse the retransmit, sacked and abandoned queues, while chunks are using 'transmitted_list' to link into these queues. It could cause NULL dereference panic if there are chunks in any of these queues when peeling off one asoc. So use the chunk member 'transmitted_list' instead in this patch.

2017-11-28sch_sfq: fix null pointer dereference at timer expirationPaolo Abeni
While converting sch_sfq to use timer_setup(), the commit cdeabbb88134 ("net: sched: Convert timers to use timer_setup()") forgot to initialize the 'sch' field. As a result, the timer callback tries to dereference a NULL pointer, and the kernel does oops. Fix it initializing such field at qdisc creation time.
