This patch improves few aspects of genphy_read_status(): - Don't initialize lpagb, it's not needed. - Move initializing phydev->speed et al before the if clause. - In auto-neg case, skip populating lp_advertising if we don't have a link. This avoids quite some unnecessary MDIO reads in case of phylib polling mode. Signed-off-by: Heiner Kallweit <hkallweit1@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>

Jakub Kicinski says: ==================== nfp: flower improvement and SFF module EEPROM The first patch in this series from Pieter improves the handling of mangle actions in TC flower offload. These used to be sent down to the driver in groups, but after Pablo N's patches they are split out causing suboptimal expression. The ramaining two patches from Dirk add support for reading SFF module EEPROM data. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>

Now that the NSP provides the ability to read from the SFF modules' EEPROM, we can use this interface to implement the ethtool callback. If the NSP only provides partial data, we log the event from within the driver but pass a success code to ethtool to prevent it from discarding the partial data.

With the introduction of flow_action_for_each pedit actions are no longer grouped together, instead pedit actions are broken out per 32 byte word. This results in an inefficient use of the action list that is pushed to hardware where each 32 byte word becomes its own action. Therefore we combine groups of 32 byte word before sending the action list to hardware.

Gustavo A. R. Silva says: ==================== cxgb3/l2t: Fix undefined behaviour and use struct_size() helper This patchset aims to fix an undefined behaviour when using a zero-sized array and, add the use of the struct_size() helper in kvzalloc(). You might consider the first patch in this series for stable. More details in the commit logs. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>

Gustavo A. R. Silva authored
One of the more common cases of allocation size calculations is finding the size of a structure that has a zero-sized array at the end, along with memory for some number of elements for that array. For example: struct foo { int stuff; struct boo entry[]; }; size = sizeof(struct foo) + count * sizeof(struct boo); instance = kvzalloc(size, GFP_KERNEL); Instead of leaving these open-coded and prone to type mistakes, we can now use the new struct_size() helper: instance = kvzalloc(struct_size(instance, entry, count), GFP_KERNEL); Notice that, in this case, variable size is not necessary, hence it is removed. This code was detected with the help of Coccinelle. Signed-off-by: Gustavo A. R. Silva <gustavo@embeddedor.com> Signed-off-by: David S. Miller <davem@davemloft.net>

The use of zero-sized array causes undefined behaviour when it is not the last member in a structure. As it happens to be in this case. Also, the current code makes use of a language extension to the C90 standard, but the preferred mechanism to declare variable-length types such as this one is a flexible array member, introduced in C99: struct foo { int stuff; struct boo array[]; }; By making use of the mechanism above, we will get a compiler warning in case the flexible array does not occur last. Which is beneficial to cultivate a high-quality code. Fixes: e48f129c ("[SCSI] cxgb3i: convert cdev->l2opt to use rcu to prevent NULL dereference") Signed-off-by: Gustavo A. R.

It turns out that struct ipv6_pinfo is not located as we think. inet6_sk_generic() and tcp_inet6_sk() disagree on 32bit kernels by 4-bytes, because struct tcp_sock has 8-bytes alignment, but ipv6_pinfo size is not a multiple of 8. sizeof(struct ipv6_pinfo): 116 (not padded to 8) I actually first coded tcp_inet6_sk() as this patch does, but thought that "container_of(tcp_sk(sk), struct tcp6_sock, tcp)" was cleaner. As Julian told me : Nobody should use tcp6_sock.inet6 directly, it should be accessed via tcp_inet6_sk() or inet6_sk(). This happened when we added the first u64 field in struct tcp_sock.

The gateway setting is not per fib6_info entry but per-fib6_nh. Add a new fib_nh_has_gw flag to fib6_nh and convert references to RTF_GATEWAY to the new flag. For IPv6 address the flag is cheaper than checking that nh_gw is non-0 like IPv4 does. While this increases fib6_nh by 8-bytes, the effective allocation size of a fib6_info is unchanged. The 8 bytes is recovered later with a fib_nh_common change. Signed-off-by: David Ahern <dsahern@gmail.com> Reviewed-by: Ido Schimmel <idosch@mellanox.com> Signed-off-by: David S.
