The code in xskq_produce_addr erroneously checked if there

Fixed a bug in which a frame could be completed more than once
when an error was returned from dev_direct_xmit(). The code
erroneously retried sending the message leading to multiple
calls to the SKB destructor and therefore multiple completions
of the same buffer to user space.
The error code in
This patch set fixes three bugs in the SKB TX path of AF_XDP.
Details in the individual commits.
The structure of the patch set is as follows:
Patch 1: Fix for lost completion message
Patch 2-3: Fix for possible multiple completions of single packet
Patch 4: Fix potential race during error
There was a potential race in the TX completion code for
the SKB case when the TX napi thread and the error path
of the sendmsg code could both call the SKB destructor
at the same time. Fixed by introducing a spin_lock in the
destructor.
Fixes: 35fcde7f8deb ("xsk: support for Tx")

This is clearly a bug.
We need to set the DMA buffer size in the HW otherwise corruption can
occur when receiving packets.
This is probably not occuring because of small MTU values and because HW
has a default value internally (which currently is bigger than default
buffer size).

You will probably have an hard time backporting this because of

Flag with FLAG_EXPECTED_FAIL the BPF_MAXINSNS tests that cannot be jited
on s390 because they exceed BPF_SIZE_MAX and fail when
CONFIG_BPF_JIT_ALWAYS_ON is set. Also set .expected_errcode to -ENOTSUPP

The recent poll change may lead to stalls for non-blocking connecting
SMC sockets, since sock_poll_wait is no longer performed on the
internal CLC socket, but on the outer SMC socket. kernel_connect() on
the internal CLC socket returns with -EINPROGRESS, but the wake up

Extend slotting with support for non-uniform distributions. This is
similar to netem's non-uniform distribution delay feature.

Patch 4 adds sizeof() operator

The variable _data in include/asm-generic/sections.h defines sections,
this causes sparse warning in pedit:
net/sched/act_pedit.c:293:35: warning: symbol '_data' shadows an earlier one
./include/asm-generic/sections.h:36:13: originally declared here

Create a main ila file that contains the module initialization functions
as well as netlink definitions. Previously these were defined in
ila_xlat and ila_common. This approach allows better extensibility.

Perform better EAGAIN handling, handle case where ila_dump_info
fails and we missed objects in the dump, and add a skip index
to skip over ila entires in a list on a rhashtable node that have
already been visited (by a previous call to ila_nl_dump).

Perform some cleanup in ILA code. This includes:
- Fix rhashtable walk for cases where nl dumps are done with muliple
function calls. Add a skip index to skip over entries in
a node that have been previously visitied. Call rhashtable_walk_peek
to avoid dropping items between calls to

I don't expect RDS apps will want to use link local address

This is not true.

Hi David,
An IPv6 regression has been introduced in 4.17.0-rc6 by
8308f3f net/ipv6: Add support for specifying metric of connected routes
The regression is that some interfaces on my test machine come
up with link-local addrs but the fe80 prefix is missing.
After this bug, I cannot send any
The concepte looks fine to me, but I have a few comments to the
implementation below.
First: I missed the last part of the discussion around automatic
detection of passthrough mode. Could you give us a short summary of
the
alternatives you tried and why they were dropped?

After commit f9d4b0c1e969 ("fib_rules: move common handling of newrule
delrule msgs into fib_nl2rule"), rule_find is strict about checking
for an existing rule. rule_find must check against all
user given attributes, else it may match against a subset
of attributes and return
1 - 100 of 174 matches
