'static' and 'static noinline' function attributes make no guarantees that
gcc/clang won't optimize them. The compiler may decide to inline 'static'
function and in such case ALLOW_ERROR_INJECT becomes meaningless. The compiler
could have inlined __add_to_page_cache_locked() in one callsite and didn't
inline in another. In such case injecting errors into it would cause
unpredictable behavior. It's worse with 'static noinline' which won't be
inlined, but it still can be optimized. Like the compiler may decide to remove
one argument or constant propagate the value depending on the callsite.
To avoid such issues make sure that these functions are global noinline.

ionic memory usage rework
Previous review comments have suggested [1],[2] that this driver
needs to rework how queue resources are managed and reconfigured
so that we don't do a full driver reset and to better handle
potential allocation failures. This patchset is intended to
address those comments.
The first few patches clean some general issues and
simplify some of the memory structures. The last 4 patches
specifically address queue parameter changes without a full

The original way of changing ring length was to completely
tear down the lif's queue structure and then rebuild it, while
running the risk of allocations that might fail in the middle
and leave us with a broken driver.
Instead, we can set up all the new queue and descriptor
allocations first, then swap them out and delete the old
allocations. If the new allocations fail, we report the error,
stay with the old setup and continue running. This gives us
a safer path, and a smaller window of time where we're not

option not to create fallback tunnels in root-ns as well. Since modules
that create fallback tunnels could be built-in and setting the sysctl
value after booting is pointless, so added a kernel cmdline options to
change this default. The default setting is preseved for backward
compatibility. The kernel command line option of fb_tunnels=initns will
set the sysctl value to 1 and will create fallback tunnels only in initns
while kernel cmdline fb_tunnels=none will set the sysctl value to 2 and
fallback tunnels are skipped in every netns.

Most of the maps do not use max_entries during verification time.
Thus, those map_meta_equal() do not need to enforce max_entries
when it is inserted as an inner map during runtime. The max_entries
check is removed from the default implementation bpf_map_meta_equal().
The prog_array_map and xsk_map are exception. Its map_gen_lookup
uses max_entries to generate inline lookup code. Thus, they will
implement its own map_meta_equal() to enforce max_entries.
Since there are only two cases now, the max_entries check
is not refactored and stays in its own .c file.

Some properties of the inner map is used in the verification time.
When an inner map is inserted to an outer map at runtime,
bpf_map_meta_equal() is currently used to ensure those properties
of the inserting inner map stays the same as the verification
time.
In particular, the current bpf_map_meta_equal() checks max_entries which
turns out to be too restrictive for most of the maps which do not use
max_entries during the verification time. It limits the use case that
wants to replace a smaller inner map with a larger inner map. There are
some maps do use max_entries during verification though. For example,
the map_gen_lookup in array_map_ops uses the max_entries to generate
the inline lookup code.
To accommodate differences between maps, the map_meta_equal is added
to bpf_map_ops. Each map-type can decide what to check when its
map is used as an inner map during runtime.
Also, some map types cannot be used as an inner map and they are
currently black listed in bpf_map_meta_alloc() in map_in_map.c.
It is not unusual that the new map types may not aware that such
blacklist exists. This patch enforces an explicit opt-in
and only allows a map to be used as an inner map if it has
implemented the map_meta_equal ops. It is based on the
discussion in [1].
All maps that support inner map has its map_meta_equal points
to bpf_map_meta_equal in this patch. A later patch will
relax the max_entries check for most maps. bpf_types.h
counts 28 map types. This patch adds 23 ".map_meta_equal"
by using coccinelle. -5 for
BPF_MAP_TYPE_PROG_ARRAY
BPF_MAP_TYPE_(PERCPU)_CGROUP_STORAGE
BPF_MAP_TYPE_STRUCT_OPS
BPF_MAP_TYPE_ARRAY_OF_MAPS
BPF_MAP_TYPE_HASH_OF_MAPS
The "if (inner_map->inner_map_meta)" check in bpf_map_meta_alloc()
is moved such that the same error is returned.

bpf_link_info.iter is used by link_query to return bpf_iter_link_info
to user space. Fields may be different, e.g., map_fd vs. map_id, so
we cannot reuse the exact structure. But make them similar, e.g.,
struct bpf_link_info {
/* common fields */
union {
struct { ... } raw_tracepoint;
struct { ... } tracing;
...
struct {
/* common fields for iter */
union {
struct {
__u32 map_id;
} map;
/* other structs for other targets */
};
};
};
};
so the structure is extensible the same way as bpf_iter_link_info.

The system for "Auto-detecting system features" located under
tools/build/ are (currently) used by perf, libbpf and bpftool. It can
contain stalled feature detection files, which are not cleaned up by
libbpf and bpftool on make clean (side-note: perf tool is correct).
Fix this by making the users invoke the make clean target.
Some details about the changes. The libbpf Makefile already had a
clean-config target (which seems to be copy-pasted from perf), but this
target was not "connected" (a make dependency) to clean target. Choose
not to rename target as someone might be using it. Did change the output

s390/qeth: updates 2020-08-27
please apply the following patch series for qeth to netdev's net-next tree.
Patch 8 makes some improvements to how we handle HW address events,
avoiding some uncertainty around processing stale events after we
switched off the feature.
Except for that it's all straight-forward cleanups.
====================
Signed-off-by: David S. Miller <davem@davemloft.net>
The current code for bridge address events has two shortcomings in its
control sequence:
1. after disabling address events via PNSO, we don't flush the remaining
events from the event_wq. So if the feature is re-enabled fast
enough, stale events could leak over.
2. PNSO and the events' arrival via the READ ccw device are unordered.
So even if we flushed the workqueue, it's difficult to say whether
the READ device might produce more events onto the workqueue
afterwards.
Fix this by
1. explicitly fencing off the events when we no longer care, in the
READ device's event handler. This ensures that once we flush the
workqueue, it doesn't get additional address events.
2. Flush the workqueue after disabling the events & fencing them off.
As the code that triggers the flush will typically hold the sbp_lock,
we need to rework the worker code to avoid a deadlock here in case
of a 'notifications-stopped' event. In case of lock contention,
requeue such an event with a delay. We'll eventually aquire the lock,
or spot that the feature has been disabled and the event can thus be
discarded.
This leaves the theoretical race that a stale event could arrive
_after_ we re-enabled ourselves to receive events again. Such an event
would be impossible to distinguish from a 'good' event, nothing we can
do about it.

queue->state is a ternary spinlock in disguise, used by
OSA's TX completion path to lock the Output Queue and flush any pending
packets on it to the device. If the Queue is already locked by our TX
code, setting the lock word to QETH_OUT_Q_LOCKED_FLUSH lets the TX
completion code move on - the TX path will later take care of things
when it unlocks the Queue.
This sort of DIY locking is a non-starter of course, just let the
TX completion path block on the spinlock when necessary. If that ends up
causing additional latency due to lock contention, then converting
the OSA path to use xmit_more is the right way to go forward.
Also slightly expand the locked section and capture all of
qeth_do_send_packet(), so that the update for the 'bufs_pack' statistics
is done race-free.
