This test already catches a netlink bug fixed by this series,
but only when running on HW with many queues. Make sure the
netdevsim instance created has a lot of queues, and constrain
the size of the recv_buffer used by netlink.
While at it test both rx and tx queues.

recv_size parameter allows constraining the buffer size for dumps.
It's useful in testing kernel handling of dump continuation,
IOW testing dumps which span multiple skbs.
Let the tests set this parameter when initializing the YNL family.
Keep the normal default, we don't want tests to unintentionally
behave very differently than normal code.

The context is supposed to record the next queue to dump,
not last dumped. If the dump doesn't fit we will restart
from the already-dumped queue, duplicating the message.

GCC performs value range tracking for variables as a way to provide better
diagnostics. One place this is regularly seen is with warnings associated
with bounds-checking, e.g. -Wstringop-overflow, -Wstringop-overread,
-Warray-bounds, etc. In order to keep the signal-to-noise ratio high,
warnings aren't emitted when a value range spans the entire value range
representable by a given variable. For example:
unsigned int len;
char dst[8];
...
memcpy(dst, src, len);
If len's value is unknown, it has the full "unsigned int" range of [0,
UINT_MAX], and GCC's compile-time bounds checks against memcpy() will
be ignored. However, when a code path has been able to narrow the range:
if (len > 16)
return;
memcpy(dst, src, len);
Then the range will be updated for the execution path. Above, len is
now [0, 16] when reading memcpy(), so depending on other optimizations,
we might see a -Wstringop-overflow warning like:
error: '__builtin_memcpy' writing between 9 and 16 bytes into region of size 8 [-Werror=stringop-overflow]
When building with CONFIG_FORTIFY_SOURCE, the fortified run-time bounds
checking can appear to narrow value ranges of lengths for memcpy(),
depending on how the compiler constructs the execution paths during
optimization passes, due to the checks against the field sizes. For
example:
if (p_size_field != SIZE_MAX &&
p_size != p_size_field && p_size_field < size)
As intentionally designed, these checks only affect the kernel warnings
emitted at run-time and do not block the potentially overflowing memcpy(),
so GCC thinks it needs to produce a warning about the resulting value
range that might be reaching the memcpy().
We have seen this manifest a few times now, with the most recent being
with cpumasks:
In function ‘bitmap_copy’,
inlined from ‘cpumask_copy’ at ./include/linux/cpumask.h:839:2,
inlined from ‘__padata_set_cpumasks’ at kernel/padata.c:730:2:

This warning is _not_ emitted when CONFIG_FORTIFY_SOURCE is disabled,
and with the recent -fdiagnostics-details we can confirm the origin of
the warning is due to FORTIFY's bounds checking:

| (2) when the condition is evaluated to true
'__padata_set_cpumasks': event 3
114 | #define __underlying_memcpy __builtin_memcpy
| ^
| |
| (3) out of array bounds here
Note that the cpumask warning started appearing since bitmap functions
were recently marked __always_inline in commit ed8cd2b3bd9f ("bitmap:
Switch from inline to __always_inline"), which allowed GCC to gain
visibility into the variables as they passed through the FORTIFY
implementation.
In order to silence these false positives but keep otherwise deterministic
compile-time warnings intact, hide the length variable from GCC with
OPTIMIZE_HIDE_VAR() before calling the builtin memcpy.
Additionally add a comment about why all the macro args have copies with
const storage.

When function tracing and function graph tracing are both enabled (in
different instances) the "parent" of some of the function tracing events
is "return_to_handler" which is the trampoline used by function graph
tracing. To fix this, ftrace_get_true_parent_ip() was introduced that
returns the "true" parent ip instead of the trampoline.
To do this, the ftrace_regs_get_stack_pointer() is used, which uses
kernel_stack_pointer(). The problem is that microblaze does not implement
kerenl_stack_pointer() so when function graph tracing is enabled, the
build fails. But microblaze also does not enabled HAVE_DYNAMIC_FTRACE_WITH_ARGS.
That option has to be enabled by the architecture to reliably get the
values from the fregs parameter passed in. When that config is not set,
the architecture can also pass in NULL, which is not tested for in that
function and could cause the kernel to crash.

A bug was discovered where the idle shadow stacks were not initialized
for offline CPUs when starting function graph tracer, and when they came
online they were not traced due to the missing shadow stack. To fix
this, the idle task shadow stack initialization was moved to using the
CPU hotplug callbacks. But it removed the initialization when the
function graph was enabled. The problem here is that the hotplug
callbacks are called when the CPUs come online, but the idle shadow
stack initialization only happens if function graph is currently
active. This caused the online CPUs to not get their shadow stack
initialized.
The idle shadow stack initialization still needs to be done when the
function graph is registered, as they will not be allocated if function
graph is not registered.

For many use cases (e.g. container images are just fetched from remote),
performance will be impacted if underlay page cache is up-to-date but
direct i/o flushes dirty pages first.
Instead, let's use buffered I/O by default to keep in sync with loop
devices and add a (re)mount option to explicitly give a try to use
direct I/O if supported by the underlying files.
The container startup time is improved as below:
[workload] docker.io/library/workpress:latest

Since commit 0a77d947f599 ("ksmbd: check outstanding simultaneous SMB
operations"), ksmbd enforces a maximum number of simultaneous operations
for a connection. The problem is that reaching the limit causes ksmbd to
close the socket, and the client has no indication that it should have
slowed down.
This behaviour can be reproduced by setting "smb2 max credits = 128" (or
lower), and transferring a large file (25GB).
smbclient fails as below:
$ smbclient //192.168.1.254/testshare -U user%pass
smb: \> put file.bin
cli_push returned NT_STATUS_USER_SESSION_DELETED
putting file file.bin as \file.bin smb2cli_req_compound_submit:
Insufficient credits. 0 available, 1 needed
NT_STATUS_INTERNAL_ERROR closing remote file \file.bin
smb: \> smb2cli_req_compound_submit: Insufficient credits. 0 available,
1 needed
Windows clients fail with 0x8007003b (with smaller files even).
Fix this by delaying reading from the socket until there's room to
allocate a request. This effectively applies backpressure on the client,
so the transfer completes, albeit at a slower rate.

The existing linked list based implementation of how ts tags are
assigned and managed is unsafe against concurrency and corner cases:
- element addition in tx processing can race against element removal
in ts queue completion,
- element removal in ts queue completion can race against element
removal in device close,
- if a large number of frames gets added to tx queue without ts queue
completions in between, elements with duplicate tag values can get
added.
Use a different implementation, based on per-port used tags bitmaps and
saved skb arrays.
Safety for addition in tx processing vs removal in ts completion is
provided by:
tag = find_first_zero_bit(...);
smp_mb();
<write rdev->ts_skb[tag]>
set_bit(...);
vs
<read rdev->ts_skb[tag]>
smp_mb();
clear_bit(...);
Safety for removal in ts completion vs removal in device close is
provided by using atomic read-and-clear for rdev->ts_skb[tag]:
ts_skb = xchg(&rdev->ts_skb[tag], NULL);
if (ts_skb)
<handle it>

There are some FW error handling paths that can cause us to

we're checking for that.
The case where this popped up was in an AER event where the

and thus ionic_dev_teardown() got called twice in a row.
The second time through the workqueue was already destroyed,
and destroy_workqueue() choked on the bad wq pointer.
We didn't hit this in AER handler testing before because at
that time we weren't using a private workqueue. Later we
replaced the use of the system workqueue with our own private
workqueue but hadn't rerun the AER handler testing since then.

If register_netdev() fails, then the driver leaks the netdev notifier.
Fix this by calling ionic_lif_unregister() on register_netdev()
failure. This will also call ionic_lif_unregister_phc() if it has
already been registered.

Use the correct attribute space for sub-message key lookup in nested
attributes when adding attributes. This fixes rt_link where the "kind"
key and "data" sub-message are nested attributes in "linkinfo".
For example:
./tools/net/ynl/cli.py \
--create \
--spec Documentation/netlink/specs/rt_link.yaml \
--do newlink \
--json '{"link": 99,
"linkinfo": { "kind": "vlan", "data": {"id": 4 } }

Packets injected by the CPU should have a SRC_PORT field equal to the
CPU port module index in the Analyzer block (ocelot->num_phys_ports).
The blamed commit copied the ocelot_ifh_set_basic() call incorrectly
from ocelot_xmit_common() in net/dsa/tag_ocelot.c. Instead of calling
with "x", it calls with BIT_ULL(x), but the field is not a port mask,
but rather a single port index.
[ side note: this is the technical debt of code duplication :( ]
The error used to be silent and doesn't appear to have other
user-visible manifestations, but with new changes in the packing
library, it now fails loudly as follows:

When receiving clc msg, the field length in smc_clc_msg_hdr indicates the
length of msg should be received from network and the value should not be
fully trusted as it is from the network. Once the value of length exceeds
the value of buflen in function smc_clc_wait_msg it may run into deadloop
when trying to drain the remaining data exceeding buflen.
This patch checks the return value of sock_recvmsg when draining data in
case of deadloop in draining.

When application sending data more than sndbuf_space, there have chances
application will sleep in epoll_wait, and will never be wakeup again. This
is caused by a race between smc_poll and smc_cdc_tx_handler.
application tasklet
smc_tx_sendmsg(len > sndbuf_space) |
epoll_wait for EPOLL_OUT,timeout=0 |
smc_poll |
if (!smc->conn.sndbuf_space) |
| smc_cdc_tx_handler
| atomic_add sndbuf_space
| smc_tx_sndbuf_nonfull
| if (!test_bit SOCK_NOSPACE)
| do not sk_write_space;
set_bit SOCK_NOSPACE; |
return mask=0; |
Application will sleep in epoll_wait as smc_poll returns 0. And
smc_cdc_tx_handler will not call sk_write_space because the SOCK_NOSPACE
has not be set. If there is no inflight cdc msg, sk_write_space will not be
called any more, and application will sleep in epoll_wait forever.
So check sndbuf_space again after NOSPACE flag is set to break the race.

BPF program types like kprobe and fentry can cause deadlocks in certain
situations. If a function takes a lock and one of these bpf programs is
hooked to some point in the function's critical section, and if the
bpf program tries to call the same function and take the same lock it will
lead to deadlock. These situations have been reported in the following
bug reports.

Prevent kprobe and fentry bpf programs from attaching to these critical
sections by removing CC_FLAGS_FTRACE for percpu_freelist.o,
bpf_lru_list.o, queue_stack_maps.o, lpm_trie.o, ringbuf.o files.
The bugs reported by syzbot are due to tracepoint bpf programs being
called in the critical sections. This patch does not aim to fix deadlocks
caused by tracepoint programs. However, it does prevent deadlocks from
occurring in similar situations due to kprobe and fentry programs.
