pull-request: bpf 2019-01-31
The following pull-request contains BPF updates for your *net* tree.
The main changes are:
1) disable preemption in sender side of socket filters, from Alexei.
2) fix two potential deadlocks in syscall bpf lookup and prog_register,
from Martin and Alexei.
3) fix BTF to allow typedef on func_proto, from Yonghong.
4) two bpftool fixes, from Jiri and Paolo.

Previously, bpf_num_possible_cpus() had a bug when calculating a
number of possible CPUs in the case of sparse CPU allocations, as
it was considering only the first range or element of
/sys/devices/system/cpu/possible.
E.g. in the case of "0,2-3" (CPU 1 is not available), the function
returned 1 instead of 3.
This patch fixes the function by making it parse all CPU ranges and
elements.

While running test_progs in a loop I found out that I'm sometimes hitting
"Didn't find expected build ID from the map" error.
Looking at stack_map_get_build_id_offset() it seems that it is racy (by

current->mm->mmap_sem).

It's GNU Make and linker specific.
The default Makefile rule looks like:
$(CC) $(CFLAGS) $(LDFLAGS) $@ $^ $(LDLIBS)
When linking is done by gcc itself, no issue, but when it needs to be passed
to proper ld, only LDLIBS follows and then ld cannot know what libs to link
with.
More detail:
https://www.gnu.org/software/make/manual/html_node/Implicit-Variables.html
LDFLAGS
Extra flags to give to compilers when they are supposed to invoke the linker,
‘ld’, such as -L. Libraries (-lfoo) should be added to the LDLIBS variable
instead.
LDLIBS
Library flags or names given to compilers when they are supposed to invoke the
linker, ‘ld’. LOADLIBES is a deprecated (but still supported) alternative to
LDLIBS. Non-library linker flags, such as -L, should go in the LDFLAGS
variable.
https://lkml.org/lkml/2010/2/10/362
tools/perf: libraries must come after objects
Link order matters, use LDLIBS instead of LDFLAGS to properly link against
libpthread.

There was a bug where the per-mm pkey state was not being preserved across
fork() in the child. fork() is performed in the pkey selftests, but all of
the pkey activity is performed in the parent. The child does not perform
any actions sensitive to pkey state.
To make the test more sensitive to these kinds of bugs, add a fork() where
the parent exits, and execution continues in the child.
To achieve this let the key exhaustion test not terminate at the first
allocation failure and fork after 2*NR_PKEYS loops and continue in the
child.

With very small change to test script we can trigger softlockup due to
bogus assignment of 'p' (policy to be examined) on restart.
Previously the two to-be-merged nodes had same address/prefixlength pair,
so no erase/reinsert was necessary, we only had to append the list from
node a to b.
If prefix lengths are different, the node has to be deleted and re-inserted
into the tree, with the updated prefix length. This was broken; due to
bogus update to 'p' this loops forever.
Add a 'restart' label and use that instead.
While at it, don't perform the unneeded reinserts of the policies that
are already sorted into the 'new' node.
A previous patch in this series made xfrm_policy_inexact_list_reinsert()
use the relative position indicator to sort policies according to age in
case priorities are identical.

The existing script lacks a policy pattern that triggers 'tree node
merges' in the kernel.
Consider adding policy affecting following subnet:
pol1: dst 10.0.0.0/22
pol2: dst 10.0.0.0/23 # adds to existing 10.0.0.0/22 node
-> no problems here. But now, lets consider reverse order:
pol1: dst 10.0.0.0/24
pol2: dst 10.0.0.0/23 # CANNOT add to existing node
When second policy gets added, the kernel must check that the new node
("10.0.0.0/23") doesn't overlap with any existing subnet.
Example:
dst 10.0.0.0/24
dst 10.0.0.1/24
dst 10.0.0.0/23
When the third policy gets added, the kernel must replace the nodes for
the 10.0.0.0/24 and 10.0.0.1/24 policies with a single one and must merge
all the subtrees/lists stored in those nodes into the new node.
The existing test cases only have overlaps with a single node, so no
merging takes place (we can always remove the 'old' node and replace
it with the new subnet prefix).
Add a few 'block policies' in a pattern that triggers this, with a priority
that will make kernel prefer the 'esp' rules.
Make sure the 'tunnel ping' tests still pass after they have been added.

When running the test on the Spectrum ASIC the generated packets are
counted on the ingress filter and injected back to the pipeline because
of the 'pass' action. The router block then drops the packets due to
checksum error, as the test generates packets with zero checksum.
When running the test on an emulator that is not as strict about
checksum errors the test fails since packets are counted twice. Once by
the emulated ASIC on its ingress filter and again by the kernel as the
emulator does not perform checksum validation and allows the packets to
be trapped by a matching host route.
Fix this by changing the action to 'drop', which will prevent the packet
from continuing further in the pipeline to the router block.
For veth pairs this change is essentially a NOP given packets are only
processed once (by the kernel).

Commit ade446403b ("net: ipv4: do not handle duplicate fragments as

as well as _some_ fragments completely covered by previously delivered
fragments, do not lead to the whole frag queue being discarded. This
makes the existing ip_defrag selftest flaky.
This patch
* makes sure that negative IPv4 defrag tests generate truly overlapping
fragments that trigger defrag queue drops;
* tests that duplicate IPv4 fragments do not trigger defrag queue drops;
* makes a couple of minor tweaks to the test aimed at increasing its code
coverage and reduce flakiness.

- Clean up of the histogram code that will facilitate adding more
features to the histograms in the future.
- Addition of str_has_prefix() and a few use cases. There currently is
a similar function strstart() that is used in a few places, but only
returns a bool and not a length. These instances will be removed in
the future to use str_has_prefix() instead.
- A few other various clean ups as well.

This Kselftest update for Linux 4.21-rc1 consists of:
- fixes, and improvements to the framework, and individual tests.
- a new media test for IR encoders from Sean Young.
- a new watchdog test option to find time left on a timer.
