Introduce 'struct bpf_spin_lock' and bpf_spin_lock/unlock() helpers to let
bpf program serialize access to other variables.
Example:
struct hash_elem {
int cnt;
struct bpf_spin_lock lock;
};
struct hash_elem * val = bpf_map_lookup_elem(&hash_map, &key);
if (val) {
bpf_spin_lock(&val->lock);
val->cnt++;
bpf_spin_unlock(&val->lock);
}
Restrictions and safety checks:
- bpf_spin_lock is only allowed inside HASH and ARRAY maps.
- BTF description of the map is mandatory for safety analysis.
- bpf program can take one bpf_spin_lock at a time, since two or more can
cause dead locks.
- only one 'struct bpf_spin_lock' is allowed per map element.
It drastically simplifies implementation yet allows bpf program to use
any number of bpf_spin_locks.
- when bpf_spin_lock is taken the calls (either bpf2bpf or helpers) are not allowed.
- bpf program must bpf_spin_unlock() before return.
- bpf program can access 'struct bpf_spin_lock' only via
bpf_spin_lock()/bpf_spin_unlock() helpers.
- load/store into 'struct bpf_spin_lock lock;' field is not allowed.
- to use bpf_spin_lock() helper the BTF description of map value must be
a struct and have 'struct bpf_spin_lock anyname;' field at the top level.
Nested lock inside another struct is not allowed.
- syscall map_lookup doesn't copy bpf_spin_lock field to user space.
- syscall map_update and program map_update do not update bpf_spin_lock field.
- bpf_spin_lock cannot be on the stack or inside networking packet.
bpf_spin_lock can only be inside HASH or ARRAY map value.
- bpf_spin_lock is available to root only and to all program types.
- bpf_spin_lock is not allowed in inner maps of map-in-map.
- ld_abs is not allowed inside spin_lock-ed region.
- tracing progs and socket filter progs cannot use bpf_spin_lock due to
insufficient preemption checks
Implementation details:
- cgroup-bpf class of programs can nest with xdp/tc programs.
Hence bpf_spin_lock is equivalent to spin_lock_irqsave.
Other solutions to avoid nested bpf_spin_lock are possible.
Like making sure that all networking progs run with softirq disabled.
spin_lock_irqsave is the simplest and doesn't add overhead to the
programs that don't use it.
- arch_spinlock_t is used when its implemented as queued_spin_lock
- archs can force their own arch_spinlock_t
- on architectures where queued_spin_lock is not available and
sizeof(arch_spinlock_t) != sizeof(__u32) trivial lock is used.
- presence of bpf_spin_lock inside map value could have been indicated via
extra flag during map_create, but specifying it via BTF is cleaner.
It provides introspection for map key/value and reduces user mistakes.
Next steps:
- allow bpf_spin_lock in other map types (like cgroup local storage)
- introduce BPF_F_LOCK flag for bpf_map_update() syscall and helper
to request kernel to grab bpf_spin_lock before rewriting the value.
That will serialize access to map elements.

====================
If test_maps/test_verifier is running against the kernel which doesn't
have _all_ BPF features enabled, it fails with an error. This patch
series tries to probe kernel support for each failed test and skip
it instead. This lets users run BPF selftests in the not-all-bpf-yes
environments and received correct PASS/NON-PASS result.
See https://www.spinics.net/lists/netdev/msg539331.html for more
context.
The series goes like this:
* patch #1 skips sockmap tests in test_maps.c if BPF_MAP_TYPE_SOCKMAP
map is not supported (if bpf_create_map fails, we probe the kernel
for support)
* patch #2 skips verifier tests if test->prog_type is not supported (if
bpf_verify_program fails, we probe the kernel for support)
* patch #3 skips verifier tests if test fixup map is not supported (if
create_map fails, we probe the kernel for support)
* next patches fix various small issues that arise from the first four:
* patch #4 sets "unknown func bpf_trace_printk#6" prog_type to
BPF_PROG_TYPE_TRACEPOINT so it is correctly skipped in
CONFIG_BPF_EVENTS=n case
* patch #5 exposes BPF_PROG_TYPE_CGROUP_{SKB,SOCK,SOCK_ADDR} only when
CONFIG_CGROUP_BPF=y, this makes verifier correctly skip appropriate
tests
v3 changes:
* rebased on top of Quentin's series which adds probes to libbpf
v2 changes:
* don't sprinkle "ifdef CONFIG_CGROUP_BPF" all around net/core/filter.c,
doing it only in the bpf_types.h is enough to disable
BPF_PROG_TYPE_CGROUP_{SKB,SOCK,SOCK_ADDR} prog types for non-cgroup
enabled kernels

net: dsa: mt7530: support MT7530 in the MT7621 SoC
This is the fourth version of a patch series supporting the MT7530 switch
as used in the MediaTek MT7621 SoC. Unlike the MediaTek MT7623 the MT7621
is built around a dual core MIPS CPU architecture. But inside it uses
basically the same 7530 switch.
This series resolves all issues I had with previous versions, and I can
now reliably use the driver on a 7621 SoC platform. These patches were
generated against linux-5.0-rc4.
The first patch enables support for the existing kernel mediatek ethernet
driver on the MT7621 SoC. This support is from Bjørn Mork, with an update
and fix by me. Using this driver fixed a number of problems I had
(TX checksums, large RX packet drop) over the staging driver
(drivers/staging/mt7621-eth).
Patch 2 modifies the mt7530 DSA driver to support the 7530 switch as
implemented in the Mediatek MT7621 SoC. The last patch updates the
devicetree bindings to reflect the new support in the mt7530 driver.
There is no real dependencies between the patches, so they can be taken
independantly.
Creating a new binding for the MT7621 seems like the only viable approach
to distinguish between a stand alone 7530 switch, the silicon module
in the MT7623 SoC and the silicon in the MT7621. Certainly the 7530 ID
register in the MT7623 and MT7621 returns the same value, "0x7530001".
Looking at the mt7530.c DSA driver it might make some sense to convert
the existing "mediatek,mcm" binding to something like "mediatek,mt7623"
to be consistent with this new MT7621 support. As far as I can tell
this is the intention of this binding.

The MediaTek MT7621 SoC device contains a 7530 switch, and the existing
linux kernel 7530 DSA switch driver can be used with it.
The bulk of the changes required stem from the 7621 having different
regulator and pad setup. The existing setup of these in the 7530
driver appears to be very specific to its implemtation in the Mediatek
7623 SoC. (Not entirely surprising given the 7623 is a quad core ARM
based SoC, and the 7621 is a dual core, dual thread MIPS based SoC).
Create a new devicetree type, "mediatek,mt7621", to support the 7530
switch in the 7621 SoC. There appears to be no usable ID register to
distinguish it from a 7530 in other hardware at runtime. This is used
to carry out the appropriate configuration and setup.

mlxsw: spectrum_acl: Include delta bits into hashtable key
The Spectrum-2 ASIC allows multiple rules to use the same mask provided
that the difference between their masks is small enough (up to 8
consecutive delta bits). A more detailed explanation is provided in
merge commit 756cd36626 ("Merge branch
'mlxsw-Introduce-algorithmic-TCAM-support'").
These delta bits are part of the rule's key and therefore rules that
only differ in their delta bits can be inserted with the same A-TCAM
mask. In case two rules share the same key and only differ in their
priority, then the second will spill to the C-TCAM.
Current code does not take the delta bits into account when checking for
duplicate rules, which leads to unnecessary spillage to the C-TCAM.
This may result in reduced scale and performance.
Patch #1 includes the delta bits in the rule's key to avoid the above
mentioned problem.
Patch #2 adds a tracepoint when a rule is inserted into the C-TCAM.
Patches #3-#5 add test cases to make sure unnecessary spillage into the
C-TCAM does not occur.

This patchset adds the support for 3 assoc_id constants: SCTP_FUTURE_ASSOC
SCTP_CURRENT_ASSOC, SCTP_ALL_ASSOC, described in rfc6458#section-7.2:
All socket options set on a one-to-one style listening socket also

often a socket option will pass a structure that includes an assoc_id
field. This field can be filled with the association identifier of a
particular association and unless otherwise specified can be filled
with one of the following constants:
SCTP_FUTURE_ASSOC: Specifies that only future associations created
after this socket option will be affected by this call.
SCTP_CURRENT_ASSOC: Specifies that only currently existing
associations will be affected by this call, and future
associations will still receive the previous default value.
SCTP_ALL_ASSOC: Specifies that all current and future associations
will be affected by this call.
The functions for many other sockopts that use assoc_id also need to be
