====================
This patch proposes to add AF_XDP support to libbpf. The main reason
for this is to facilitate writing applications that use AF_XDP by
offering higher-level APIs that hide many of the details of the AF_XDP
uapi. This is in the same vein as libbpf facilitates XDP adoption by
offering easy-to-use higher level interfaces of XDP
functionality. Hopefully this will facilitate adoption of AF_XDP, make
applications using it simpler and smaller, and finally also make it
possible for applications to benefit from optimizations in the AF_XDP
user space access code. Previously, people just copied and pasted the
code from the sample application into their application, which is not
desirable.
The proposed interface is composed of two parts:
* Low-level access interface to the four rings and the packet
* High-level control plane interface for creating and setting up umems
and AF_XDP sockets. This interface also loads a simple XDP program
that routes all traffic on a queue up to the AF_XDP socket.
The sample program has been updated to use this new interface and in
that process it lost roughly 300 lines of code. I cannot detect any
performance degradations due to the use of this library instead of the
previous functions that were inlined in the sample application. But I
did measure this on a slower machine and not the Broadwell that we
normally use.
The rings are now called xsk_ring and when a producer operates on
it. It is xsk_ring_prod and for a consumer it is xsk_ring_cons. This
way we can get some compile time error checking that the rings are
used correctly.
Comments and contenplations:
* The current behaviour is that the library loads an XDP program (if
requested to do so) but the clean up of this program is left to the
application. It would be possible to implement this cleanup in the
library, but it would require state to be kept on netdev level,
which there is none at the moment, and the synchronization of this
between processes. All this adding complexity. But when we get an
XDP program per queue id, then it becomes trivial to also remove the
XDP program when the application exits. This proposal from Jesper,
Björn and others will also improve the performance of libbpf, since
most of the XDP program code can be removed when that feature is
supported.
* In a future release, I am planning on adding a higher level data
plane interface too. This will be based around recvmsg and sendmsg
with the use of struct iovec for batching, without the user having
to know anything about the underlying four rings of an AF_XDP
socket. There will be one semantic difference though from the
standard recvmsg and that is that the kernel will fill in the iovecs
instead of the application. But the rest should be the same as the
libc versions so that application writers feel at home.
Patch 1: adds AF_XDP support in libbpf
Patch 2: updates the xdpsock sample application to use the libbpf functions
Patch 3: Documentation update to help first time users
Changes v5 to v6:
* Fixed prog_fd bug found by Xiaolong Ye. Thanks!
Changes v4 to v5:
* Added a FAQ to the documentation
* Removed xsk_umem__get_data and renamed xsk_umem__get_dat_raw to
xsk_umem__get_data
* Replaced the netlink code with bpf_get_link_xdp_id()
* Dynamic allocation of the map sizes. They are now sized after
the max number of queueus on the netdev in question.
Changes v3 to v4:
* Dropped the pr_*() patch in favor of Yonghong Song's patch set
* Addressed the review comments of Daniel Borkmann, mainly leaking
of file descriptors at clean up and making the data plane APIs
all static inline (with the exception of xsk_umem__get_data that
uses an internal structure I do not want to expose).
* Fixed the netlink callback as suggested by Maciej Fijalkowski.
* Removed an unecessary include in the sample program as spotted by
Ilia Fillipov.
Changes v2 to v3:
* Added automatic loading of a simple XDP program that routes all
traffic on a queue up to the AF_XDP socket. This program loading
can be disabled.
* Updated function names to be consistent with the libbpf naming
convention
* Moved all code to xsk.[ch]
* Removed all the XDP program loading code from the sample since
this is now done by libbpf
* The initialization functions now return a handle as suggested by
Alexei
* const statements added in the API where applicable.
Changes v1 to v2:
* Fixed cleanup of library state on error.
* Moved API to initial version
* Prefixed all public functions by xsk__ instead of xsk_
* Added comment about changed default ring sizes, batch size and umem
size in the sample application commit message
* The library now only creates an Rx or Tx ring if the respective
parameter is != NULL

This commit converts the xdpsock sample application to use the AF_XDP
functions present in libbpf. This cuts down the size of it by nearly
300 lines of code.
The default ring sizes plus the batch size has been increased and the
size of the umem area has decreased. This so that the sample application
will provide higher throughput. Note also that the shared umem code
has been removed from the sample as this is not supported by libbpf
at this point in time.

net: sched: pie: align PIE implementation with RFC 8033
The current implementation of the PIE queuing discipline is according to the
IETF draft [http://tools.ietf.org/html/draft-pan-aqm-pie-00] and the paper
[PIE: A Lightweight Control Scheme to Address the Bufferbloat Problem].
However, a lot of necessary modifications and enhancements have been proposed
in RFC 8033, which have not yet been incorporated in the source code of Linux.
This patch series helps in achieving the same.
Performance tests carried out using Flent [https://flent.org/]
Changes from v2 to v3:
- Used div_u64() instead of direct division after explicit type casting as
recommended by David
Changes from v1 to v2:
- Excluded the patch setting PIE dynamically active/inactive as the test
results were unsatisfactory
- Fixed a scaling issue when adding more auto-tuning cases which caused
local variables to underflow
- Changed the long if/else chain to a loop as suggested by Stephen
- Changed the position of the accu_prob variable in the pie_vars
structure as recommended by Stephen

Random dropping of packets to achieve latency control may
introduce outlier situations where packets are dropped too
close to each other or too far from each other. This can
cause the real drop percentage to temporarily deviate from
the intended drop probability. In certain scenarios, such
as a small number of simultaneous TCP flows, these
deviations can cause significant deviations in link
utilization and queuing latency.
RFC 8033 suggests using a derandomization mechanism to avoid
these deviations.

The current implementation scales the local alpha and beta
variables in the calculate_probability function by the same
amount for all values of drop probability below 1%.
RFC 8033 suggests using additional cases for auto-tuning
alpha and beta when the drop probability is less than 1%.
In order to add more auto-tuning cases, MAX_PROB must be
scaled by u64 instead of u32 to prevent underflow when
scaling the local alpha and beta variables in the
calculate_probability function.

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 = kzalloc(size, GFP_KERNEL)
Instead of leaving these open-coded and prone to type mistakes, we can
now use the new struct_size() helper:
instance = kzalloc(struct_size(instance, entry, count), GFP_KERNEL)
Notice that, in this case, variable alloc_size is not necessary, hence
it is removed.

100GbE Intel Wired LAN Driver Updates 2019-02-22
This series contains updates to the ice driver only.
Bruce adds the __always_unused attribute to a parameter to avoid
compiler warnings when using -Wunused-parameter. Fixed unnecessary
type-casting and the use of sizeof(). Fix the allocation of structs
that have become memory hogs, so allocate them in heaps and fix all the
associated references. Fixed the "possible" numeric overflow issues
that were caught with static analysis.
Maciej fixes the maximum MTU calculation by taking into account double
VLAN tagging amd ensure that the operations are done in the correct
order.
Victor fixes the supported node calculation, where we were not taking
into account if there is space to add the new VSI or intermediate node
above that layer, then it is not required to continue the calculation.
Added a check for a leaf node presence for a given VSI, which is needed
before removing a VSI.
Jake fixes an issue where the VSI list is shared, so simply removing a
VSI from the list will cause issues for the other users who reference
the list. Since we also free the memory, this could lead to
segmentation faults.
Brett fixes an issue where driver unload could cause a system reboot
when intel_iommu=on parameter is set. The issue is that we are not
clearing the CAUSE_ENA bit for the appropriate control queues register
when freeing the miscellaneous interrupt vector.
Mitch is so kind, he prevented spamming the VF with link messages when
the link status really has not changed. Updates the driver to use the
absolute vector ID and not the per-PF vector ID for the VF MSIx vector
allocation.
Lukasz fixes the ethtool pause parameter for the ice driver, which was
originally based off the link status but is now based off the PHY
configuration. This is to resolve an issue where pause parameters could
be set while link was down.
Jesse updates the string that reports statistics so the string does not
get modified at runtime and cause reports of string truncation.

Syzbot found out that running BPF_PROG_TEST_RUN with repeat=0xffffffff
makes process unkillable. The problem is that when CONFIG_PREEMPT is
enabled, we never see need_resched() return true. This is due to the
fact that preempt_enable() (which we do in bpf_test_run_one on each
iteration) now handles resched if it's needed.
Let's disable preemption for the whole run, not per test. In this case
we can properly see whether resched is needed.
Let's also properly return -EINTR to the userspace in case of a signal
interrupt.
This is a follow up for a recently fixed issue in bpf_test_run, see
