While investigating hosts with high cgroup memory pressures, Tejun
found culprit zombie tasks that had were holding on to a lot of
memory, had SIGKILL pending, but were stuck in memory.high reclaim.
In the past, we used to always force-charge allocations from tasks
that were exiting in order to accelerate them dying and freeing up
their rss. This changed for memory.max in a4ebf1b6ca1e ("memcg:
prohibit unconditional exceeding the limit of dying tasks"); it noted
that this can cause (userspace inducable) containment failures, so it
added a mandatory reclaim and OOM kill cycle before forcing charges.
At the time, memory.high enforcement was handled in the userspace
return path, which isn't reached by dying tasks, and so memory.high
was still never enforced by dying tasks.
When c9afe31ec443 ("memcg: synchronously enforce memory.high for large
overcharges") added synchronous reclaim for memory.high, it added
unconditional memory.high enforcement for dying tasks as well. The
callstack shows that this path is where the zombie is stuck in.
We need to accelerate dying tasks getting past memory.high, but we
cannot do it quite the same way as we do for memory.max: memory.max is
enforced strictly, and tasks aren't allowed to move past it without
FIRST reclaiming and OOM killing if necessary. This ensures very small
levels of excess. With memory.high, though, enforcement happens lazily
after the charge, and OOM killing is never triggered. A lot of
concurrent threads could have pushed, or could actively be pushing,
the cgroup into excess. The dying task will enter reclaim on every
allocation attempt, with little hope of restoring balance.
To fix this, skip synchronous memory.high enforcement on dying tasks
altogether again. Update memory.high path documentation while at it.

commit efa7df3e3bb5 ("mm: align larger anonymous mappings on THP
boundaries") incured regression for stress-ng pthread benchmark [1]. It
is because THP get allocated to pthread's stack area much more possible
than before. Pthread's stack area is allocated by mmap without
VM_GROWSDOWN or VM_GROWSUP flag, so kernel can't tell whether it is a
stack area or not.
The MAP_STACK flag is used to mark the stack area, but it is a no-op on
Linux. Mapping MAP_STACK to VM_NOHUGEPAGE to prevent from allocating THP
for such stack area.
With this change the stack area looks like:

uprobes passes an unaligned page mapping address to
folio_add_new_anon_rmap(), which ends up triggering a VM_BUG_ON() we
recently extended in commit 372cbd4d5a066 ("mm: non-pmd-mappable, large
folios for folio_add_new_anon_rmap()").
Arguably, this is uprobes code doing something wrong; however, for the
time being it would have likely worked in rmap code because
__folio_set_anon() would set folio->index to the same value.
Looking at __replace_page(), we'd also pass slightly wrong values to
mmu_notifier_range_init(), page_vma_mapped_walk(), flush_cache_page(),
ptep_clear_flush() and set_pte_at_notify(). I suspect most of them are
fine, but let's just mark the introducing commit as the one needed fixing.
I don't think CC stable is warranted.
We'll add more sanity checks in rmap code separately, to make sure that we
always get properly aligned addresses.

has_extra_refcount() makes the assumption that the page cache adds a ref
count of 1 and subtracts this in the extra_pins case. Commit a08c7193e4f1
(mm/filemap: remove hugetlb special casing in filemap.c) modifies
__filemap_add_folio() by calling folio_ref_add(folio, nr); for all cases
(including hugtetlb) where nr is the number of pages in the folio. We
should adjust the number of references coming from the page cache by
subtracing the number of pages rather than 1.
In hugetlbfs_read_iter(), folio_test_has_hwpoisoned() is testing the wrong
flag as, in the hugetlb case, memory-failure code calls
folio_test_set_hwpoison() to indicate poison. folio_test_hwpoison() is
the correct function to test for that flag.
After these fixes, the hugetlb hwpoison read selftest passes all cases.

ra_alloc_folio() marks a page that should trigger next round of async
readahead. However it rounds up computed index to the order of page being
allocated. This can however lead to multiple consecutive pages being
marked with readahead flag. Consider situation with index == 1, mark ==
1, order == 0. We insert order 0 page at index 1 and mark it. Then we
bump order to 1, index to 2, mark (still == 1) is rounded up to 2 so page
at index 2 is marked as well. Then we bump order to 2, index is
incremented to 4, mark gets rounded to 4 so page at index 4 is marked as
well. The fact that multiple pages get marked within a single readahead
window confuses the readahead logic and results in readahead window being
trimmed back to 1. This situation is triggered in particular when maximum
readahead window size is not a power of two (in the observed case it was
768 KB) and as a result sequential read throughput suffers.
Fix the problem by rounding 'mark' down instead of up. Because the index
is naturally aligned to 'order', we are guaranteed 'rounded mark' == index
iff 'mark' is within the page we are allocating at 'index' and thus
exactly one page is marked with readahead flag as required by the
readahead code and sequential read performance is restored.
This effectively reverts part of commit b9ff43dd2743 ("mm/readahead: Fix
readahead with large folios"). The commit changed the rounding with the
rationale:
"... we were setting the readahead flag on the folio which contains the
last byte read from the block. This is wrong because we will trigger
readahead at the end of the read without waiting to see if a subsequent
read is going to use the pages we just read."
Although this is true, the fact is this was always the case with read
sizes not aligned to folio boundaries and large folios in the page cache
just make the situation more obvious (and frequent). Also for sequential
read workloads it is better to trigger the readahead earlier rather than
later. It is true that the difference in the rounding and thus earlier
triggering of the readahead can result in reading more for semi-random
workloads. However workloads really suffering from this seem to be rare.
In particular I have verified that the workload described in commit
b9ff43dd2743 ("mm/readahead: Fix readahead with large folios") of reading
random 100k blocks from a file like:
[reader]
bs=100k
rw=randread
numjobs=1
size=64g
runtime=60s
is not impacted by the rounding change and achieves ~70MB/s in both cases.

In bpf_struct_ops_map_alloc, it needs to check for NULL in the returned
pointer of bpf_get_btf_vmlinux() when CONFIG_DEBUG_INFO_BTF is not set.
ENOTSUPP is used to preserve the same behavior before the
struct_ops kmod support.
In the function check_struct_ops_btf_id(), instead of redoing the
bpf_get_btf_vmlinux() that has already been done in syscall.c, the fix
here is to check for prog->aux->attach_btf_id.
BPF_PROG_TYPE_STRUCT_OPS must require attach_btf_id and syscall.c
guarantees a valid attach_btf as long as attach_btf_id is set.
When attach_btf_id is not set, this patch returns -ENOTSUPP
because it is what the selftest in test_libbpf_probe_prog_types()
and libbpf_probes.c are expecting for feature probing purpose.
Changes from v1:
- Remove an unnecessary NULL check in check_struct_ops_btf_id()

nfp: flower: a few small conntrack offload fixes
This small series addresses two bugs in the nfp conntrack offloading
code.
The first patch is a check to prevent offloading for a case which is
currently not supported by the nfp.
The second patch fixes up parsing of layer4 mangling code so it can be
correctly offloaded. Since the masks are an inverse mask and we are
shifting it so it can be packed together with the destination we
effectively need to 'clear' the lower bits of the mask by setting it to
0xFFFF.

The nfp driver will merge the tp source port and tp destination port
into one dword which the offset must be zero to do hardware offload.
However, the mangle action for the tp source port and tp destination
port is separated for tc ct action. Modify the mangle action for the
FLOW_ACT_MANGLE_HDR_TYPE_TCP and FLOW_ACT_MANGLE_HDR_TYPE_UDP to
satisfy the nfp driver offload check for the tp port.
The mangle action provides a 4B value for source, and a 4B value for
the destination, but only 2B of each contains the useful information.
For offload the 2B of each is combined into a single 4B word. Since the
incoming mask for the source is '0xFFFF<mask>' the shift-left will
throw away the 0xFFFF part. When this gets combined together in the
offload it will clear the destination field. Fix this by setting the
lower bits back to 0xFFFF, effectively doing a rotate-left operation on
the mask.

The nfp offload flow pay will not allocate a mask id when the out port
is openvswitch internal port. This is because these flows are used to
configure the pre_tun table and are never actually send to the firmware
as an add-flow message. When a tc rule which action contains ct and
the post ct entry's out port is openvswitch internal port, the merge
offload flow pay with the wrong mask id of 0 will be send to the
firmware. Actually, the nfp can not support hardware offload for this
situation, so return EOPNOTSUPP.

The busywait timeout value is a millisecond, not a second. So the
current setting 2 is too small. On slow/busy host (or VMs) the
current timeout can expire even on "correct" execution, causing random
failures. Let's copy the WAIT_TIMEOUT from forwarding/lib.sh and set
BUSYWAIT_TIMEOUT here.

Add a new helper, bch2_hash_lookup_in_snapshot(), for when we're not
operating in a subvolume and already have a snapshot ID, and then use it
in lookup_lostfound() -> __lookup_dirent().
This is a bugfix - lookup_lostfound() doesn't take a subvolume ID, we
were passing a nonsense subvolume ID before, and don't have one to pass
since we may be operating in an interior snapshot node that doesn't have
a subvolume ID.

This series address self-tests failures for udp gro-related tests.
The first patch addresses the main problem I observe locally - the XDP
program required by such tests, xdp_dummy, is currently build in the
ebpf self-tests directory, not available if/when the user targets net
only. Arguably is more a refactor than a fix, but still targeting net

The second patch fixes the integration of such tests with the build

The UDP GRO forwarding test still hard-code an arbitrary pause
to wait for the UDP listener becoming ready in background.
That causes sporadic failures depending on the host load.

Several net tests requires an XDP program build under the ebpf
directory, and error out if such program is not available.
That makes running successful net test hard, let's duplicate into the

it, and finally dropping the bogus dependency.
