Subject: pull-request: bpf-next 2019-07-03
Hi David,
The following pull-request contains BPF updates for your *net-next* tree.
There is a minor merge conflict in mlx5 due to 8960b38932be ("linux/dim:
Rename externally used net_dim members") which has been pulled into your
tree in the meantime, but resolution seems not that bad ... getting current
bpf-next out now before there's coming more on mlx5. ;) I'm Cc'ing Saeed
just so he's aware of the resolution below:
** First conflict in drivers/net/ethernet/mellanox/mlx5/core/en_main.c:
<<<<<<< HEAD
static int mlx5e_open_cq(struct mlx5e_channel *c,
struct dim_cq_moder moder,
struct mlx5e_cq_param *param,
struct mlx5e_cq *cq)
=======
int mlx5e_open_cq(struct mlx5e_channel *c, struct net_dim_cq_moder moder,
struct mlx5e_cq_param *param, struct mlx5e_cq *cq)
>>>>>>> e5a3e259ef239f443951d401db10db7d426c9497
Resolution is to take the second chunk and rename net_dim_cq_moder into
dim_cq_moder. Also the signature for mlx5e_open_cq() in ...
drivers/net/ethernet/mellanox/mlx5/core/en.h +977
... and in mlx5e_open_xsk() ...
drivers/net/ethernet/mellanox/mlx5/core/en/xsk/setup.c +64
... needs the same rename from net_dim_cq_moder into dim_cq_moder.
** Second conflict in drivers/net/ethernet/mellanox/mlx5/core/en_main.c:
<<<<<<< HEAD
int cpu = cpumask_first(mlx5_comp_irq_get_affinity_mask(priv->mdev, ix));
struct dim_cq_moder icocq_moder = {0, 0};
struct net_device *netdev = priv->netdev;
struct mlx5e_channel *c;
unsigned int irq;
=======
struct net_dim_cq_moder icocq_moder = {0, 0};
>>>>>>> e5a3e259ef239f443951d401db10db7d426c9497
Take the second chunk and rename net_dim_cq_moder into dim_cq_moder
as well.
Let me know if you run into any issues. Anyway, the main changes are:
1) Long-awaited AF_XDP support for mlx5e driver, from Maxim.
2) Addition of two new per-cgroup BPF hooks for getsockopt and
setsockopt along with a new sockopt program type which allows more
fine-grained pass/reject settings for containers. Also add a sock_ops
callback that can be selectively enabled on a per-socket basis and is
executed for every RTT to help tracking TCP statistics, both features
from Stanislav.
3) Follow-up fix from loops in precision tracking which was not propagating
precision marks and as a result verifier assumed that some branches were
not taken and therefore wrongly removed as dead code, from Alexei.
4) Fix BPF cgroup release synchronization race which could lead to a
double-free if a leaf's cgroup_bpf object is released and a new BPF
program is attached to the one of ancestor cgroups in parallel, from Roman.
5) Support for bulking XDP_TX on veth devices which improves performance
in some cases by around 9%, from Toshiaki.
6) Allow for lookups into BPF devmap and improve feedback when calling into
bpf_redirect_map() as lookup is now performed right away in the helper
itself, from Toke.
7) Add support for fq's Earliest Departure Time to the Host Bandwidth
Manager (HBM) sample BPF program, from Lawrence.
8) Various cleanups and minor fixes all over the place from many others.

Thanks a lot!
