2017-11-30net/reuseport: drop legacy codePaolo Abeni
Since commit e32ea7e74727 ("soreuseport: fast reuseport UDP socket selection") and commit c125e80b8868 ("soreuseport: fast reuseport TCP socket selection") the relevant reuseport socket matching the current packet is selected by the reuseport_select_sock() call. The only exceptions are invalid BPF filters/filters returning out-of-range indices. In the latter case the code implicitly falls back to using the hash demultiplexing, but instead of selecting the socket inside the reuseport_select_sock() function, it relies on the hash selection logic introduced with the early soreuseport implementation. With this patch, in case of a BPF filter returning a bad socket index value, we fall back to hash-based selection inside the reuseport_select_sock() body, so that we can drop some duplicate code in the ipv4 and ipv6 stack. This also allows faster lookup in the above scenario and will allow us to avoid computing the hash value for successful, BPF based demultiplexing - in a later patch.

On the A80 the pins on port B can trigger interrupts, and those are assigned to the second interrupt bank. Having two pins assigned to the same interrupt bank/pin combination does not look healthy (instead more like a copy&paste bug from pins PA14-PA16), so fix the interrupt bank for pins PB14-PB16, which is actually 1.

2017-11-30Merge branch 'net-dst_entry-shrink'David S. Miller
David Miller says: ==================== net: Significantly shrink the size of routes. Through a combination of several things, our route structures are larger than they need to be. Mostly this stems from having members in dst_entry which are only used by one class of routes. So the majority of the work in this series is about "un-commoning" these members and pushing them into the type specific structures. Unfortunately, IPSEC needed the most surgery. The majority of the changes here had to do with bundle creation and management. The other issue is the refcount alignment in dst_entry. Once we get rid of the not-so-common members, it really opens the door to removing that alignment entirely. I think the new layout looks really nice, so I'll reproduce it here: struct net_device *dev; struct dst_ops *ops; unsigned long _metrics; unsigned long expires; struct xfrm_state *xfrm; int (*input)(struct sk_buff *); int (*output)(struct net *net, struct sock *sk, struct sk_buff *skb); unsigned short flags; short obsolete; unsigned short header_len; unsigned short trailer_len; atomic_t __refcnt; int __use; unsigned long lastuse; struct lwtunnel_state *lwtstate; struct rcu_head rcu_head; short error; short __pad; __u32 tclassid; (This is for 64-bit, on 32-bit the __refcnt comes at the very end) So, the good news: 1) struct dst_entry shrinks from 160 to 112 bytes. 2) struct rtable shrinks from 216 to 168 bytes. 3) struct rt6_info shrinks from 384 to 320 bytes. Enjoy. v2: Collapse some patches logically based upon feedback.

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.

2017-11-30xfrm: 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>

2017-11-30gpio: 74x164: Fix crash during .remove()Geert Uytterhoeven
Commit 7ebc194d0fd4bb0f ("gpio: 74x164: Introduce 'enable-gpios' property") added a new member gpiod_oe to the end of the struct gen_74x164_chip, after the zero-length buffer array. However, this buffer is a flexible array, allocated together with the structure during .probe(). As the buffer is no longer the last member, writing to it corrupts the newly added member after it. During device removal, the corrupted member will be used as a pointer, leading to a crash. This went unnoticed, as the flexible array was declared as "buffer[0]" instead of "buffer[]", and thus did not trigger a "flexible array member not at end of struct" error from gcc. Move the gpiod_oe field up to fix this, and drop the zero from the array size to prevent future similar bugs.

v4l2_async_register_subdev_sensor_common() is only provided when CONFIG_V4L2_FWNODE is enabled, otherwise we get a link failure: drivers/media/i2c/et8ek8/et8ek8_driver.o: In function `et8ek8_probe': et8ek8_driver.c:(.text+0x884): undefined reference to `v4l2_async_register_subdev_sensor_common' This adds a Kconfig 'select' statement like all the other users of this interface have.

2017-11-30media: rc: partial revert of "media: rc: per-protocol repeat period"Sean Young
Since commit d57ea877af38 ("media: rc: per-protocol repeat period"), most IR protocols have a lower keyup timeout. This causes problems on the ite-cir, which has default IR timeout of 200ms. Since the IR decoders read the trailing space, with a IR timeout of 200ms, the last keydown will have at least a delay of 200ms. This is more than the protocol timeout of e.g. rc-6 (which is 164ms). As a result the last IR will be interpreted as a new keydown event, and we get two keypresses. Revert the protocol timeout to 250ms, except for cec which needs a timeout of 550ms.
