mptcp: give rcvlowat some love

The MPTCP protocol allow setting sk_rcvlowat, but the value there
is currently ignored.

Additionally, the default subflows sk_rcvlowat basically disables per
subflow delayed ack: the MPTCP protocol move the incoming data from the
subflows into the msk socket as soon as the TCP stacks invokes the subflow
data_ready callback. Later, when __tcp_ack_snd_check() takes action,
the subflow-level copied_seq matches rcv_nxt, and that mandate for an
immediate ack.

Let the mptcp receive path be aware of such threshold, explicitly tracking
the amount of data available to be ready and checking vs sk_rcvlowat in
mptcp_poll() and before waking-up readers.

Additionally implement the set_rcvlowat() callback, to properly handle
the rcvbuf auto-tuning on sk_rcvlowat changes.

Finally to properly handle delayed ack, force the subflow level threshold
to 0 and instead explicitly ask for an immediate ack when the msk level th
is not reached.

s390/qeth: replace deprecated strncpy with strscpy

strncpy() is deprecated for use on NUL-terminated destination strings
[1] and as such we should prefer more robust and less ambiguous string
interfaces.

We expect new_entry->dbf_name to be NUL-terminated based on its use with
strcmp():
|       if (strcmp(entry->dbf_name, name) == 0) {

Moreover, NUL-padding is not required as new_entry is kzalloc'd just
before this assignment:
|       new_entry = kzalloc(sizeof(struct qeth_dbf_entry), GFP_KERNEL);

... rendering any future NUL-byte assignments (like the ones strncpy()
does) redundant.

Considering the above, a suitable replacement is `strscpy` [2] due to
the fact that it guarantees NUL-termination on the destination buffer
without unnecessarily NUL-padding.

This series from Davide converts most of the MPTCP Netlink interface
(plus uAPI bits) to use sources generated by YNL using a YAML spec file.

This new YAML file is useful to validate the API and to generate a good

Patch 1 modifies YNL spec to support "uns-admin-perm" for genetlink
legacy.

Patch 2 adds support for validating exact length of netlink attrs.

Patch 3 converts Netlink structures from small_ops to ops to prepare the
switch to YAML.

Patch 4 adds the Netlink YAML spec for MPTCP.

Patch 5 adds and uses a new header file generated from the new YAML
spec.

Patch 6 renames some handlers to match the ones generated from the YAML

Before sockets became aware of net-memcg's memory pressure since
commit e1aab161e013 ("socket: initial cgroup code."), the memory
usage would be granted to raise if below average even when under
protocol's pressure. This provides fairness among the sockets of
same protocol.

That commit changes this because the heuristic will also be
effective when only memcg is under pressure which makes no sense.
So revert that behavior.

After reverting, __sk_mem_raise_allocated() no longer considers
memcg's pressure. As memcgs are isolated from each other w.r.t.
memory accounting, consuming one's budget won't affect others.
So except the places where buffer sizes are needed to be tuned,
allow workloads to use the memory they are provisioned.

page_pool: introduce page_pool_alloc() API

Currently page pool supports the below use cases:
use case 1: allocate page without page splitting using
            page_pool_alloc_pages() API if the driver knows
            that the memory it need is always bigger than
            half of the page allocated from page pool.
use case 2: allocate page frag with page splitting using
            page_pool_alloc_frag() API if the driver knows
            that the memory it need is always smaller than
            or equal to the half of the page allocated from
            page pool.

There is emerging use case [1] & [2] that is a mix of the
above two case: the driver doesn't know the size of memory it
need beforehand, so the driver may use something like below to
allocate memory with least memory utilization and performance
penalty:

if (size << 1 > max_size)
page = page_pool_alloc_pages();
else
page = page_pool_alloc_frag();

To avoid the driver doing something like above, add the
page_pool_alloc() API to support the above use case, and update
the true size of memory that is acctually allocated by updating
'*size' back to the driver in order to avoid exacerbating
truesize underestimate problem.

Rename page_pool_free() which is used in the destroy process to
__page_pool_destroy() to avoid confusion with the newly added
API.

Yunsheng Lin [Fri, 20 Oct 2023 09:59:48 +0000 (17:59 +0800)]
page_pool: unify frag_count handling in page_pool_is_last_frag()

Currently when page_pool_create() is called with
PP_FLAG_PAGE_FRAG flag, page_pool_alloc_pages() is only
allowed to be called under the below constraints:
1. page_pool_fragment_page() need to be called to setup
   page->pp_frag_count immediately.
2. page_pool_defrag_page() often need to be called to drain
   the page->pp_frag_count when there is no more user will
   be holding on to that page.

Those constraints exist in order to support a page to be
split into multi fragments.

And those constraints have some overhead because of the
cache line dirtying/bouncing and atomic update.

Those constraints are unavoidable for case when we need a
page to be split into more than one fragment, but there is
also case that we want to avoid the above constraints and
their overhead when a page can't be split as it can only
hold a fragment as requested by user, depending on different
use cases:
use case 1: allocate page without page splitting.
use case 2: allocate page with page splitting.
use case 3: allocate page with or without page splitting
            depending on the fragment size.

Currently page pool only provide page_pool_alloc_pages() and
page_pool_alloc_frag() API to enable the 1 & 2 separately,
so we can not use a combination of 1 & 2 to enable 3, it is
not possible yet because of the per page_pool flag
PP_FLAG_PAGE_FRAG.

So in order to allow allocating unsplit page without the
overhead of split page while still allow allocating split
page we need to remove the per page_pool flag in
page_pool_is_last_frag(), as best as I can think of, it seems
there are two methods as below:
1. Add per page flag/bit to indicate a page is split or
   not, which means we might need to update that flag/bit
   everytime the page is recycled, dirtying the cache line
   of 'struct page' for use case 1.
2. Unify the page->pp_frag_count handling for both split and
   unsplit page by assuming all pages in the page pool is split
   into a big fragment initially.

As page pool already supports use case 1 without dirtying the
cache line of 'struct page' whenever a page is recyclable, we
need to support the above use case 3 with minimal overhead,
especially not adding any noticeable overhead for use case 1,
and we are already doing an optimization by not updating
pp_frag_count in page_pool_defrag_page() for the last fragment
user, this patch chooses to unify the pp_frag_count handling
to support the above use case 3.

There is no noticeable performance degradation and some
justification for unifying the frag_count handling with this
patch applied using a micro-benchmark testing in [1].

ZhengHan Wang [Wed, 18 Oct 2023 10:30:55 +0000 (12:30 +0200)]
Bluetooth: Fix double free in hci_conn_cleanup

syzbot reports a slab use-after-free in hci_conn_hash_flush [1].
After releasing an object using hci_conn_del_sysfs in the
hci_conn_cleanup function, releasing the same object again
using the hci_dev_put and hci_conn_put functions causes a double free.
Here's a simplified flow:

hci_conn_del_sysfs:
  hci_dev_put
    put_device
      kobject_put
        kref_put
          kobject_release
            kobject_cleanup
              kfree_const
                kfree(name)

hci_dev_put:
  ...
    kfree(name)

hci_conn_put:
  put_device
    ...
      kfree(name)

This patch drop the hci_dev_put and hci_conn_put function
call in hci_conn_cleanup function, because the object is
freed in hci_conn_del_sysfs function.

This patch also fixes the refcounting in hci_conn_add_sysfs() and
hci_conn_del_sysfs() to take into account device_add() failures.

This fixes CVE-2023-28464.

Bluetooth: msft: __hci_cmd_sync() doesn't return NULL

The __hci_cmd_sync() function doesn't return NULL.  Checking for NULL
doesn't make the code safer, it just confuses people.

When a function returns both error pointers and NULL then generally the
NULL is a kind of success case.  For example, maybe we look up an item
then errors mean we ran out of memory but NULL means the item is not
found.  Or if we request a feature, then error pointers mean that there
was an error but NULL means that the feature has been deliberately
turned off.

In this code it's different.  The NULL is handled as if there is a bug
in __hci_cmd_sync() where it accidentally returns NULL instead of a
proper error code.  This was done consistently until commit 9e14606d8f38
("Bluetooth: msft: Extended monitor tracking by address filter") which
deleted the work around for the potential future bug and treated NULL as
success.

Predicting potential future bugs is complicated, but we should just fix
them instead of working around them.  Instead of debating whether NULL
is failure or success, let's just say it's currently impossible and
delete the dead code.

Bluetooth: qca: add support for QCA2066

This patch adds support for QCA2066 firmware patch and NVM downloading.
as the RF performance of QCA2066 SOC chip from different foundries may
vary. Therefore we use different NVM to configure them based on board ID.

Changes in v2
 - optimize the function qca_generate_hsp_nvm_name
 - remove redundant debug code for function qca_read_fw_board_id

Bluetooth: ISO: Set CIS bit only for devices with CIS support

Currently the CIS bit that can be set by the host is set for any device
that has CIS or BIS support. In reality, devices that support BIS may not
allow that bit to be set and so, the HCI bring up fails for them.

This commit fixes this by only setting the bit for CIS capable devices.

Bluetooth: ISO: Pass BIG encryption info through QoS

This enables a broadcast sink to be informed if the PA
it has synced with is associated with an encrypted BIG,
by retrieving the socket QoS and checking the encryption
field.

After PA sync has been successfully established and the
first BIGInfo advertising report is received, a new hcon
is added and notified to the ISO layer. The ISO layer
sets the encryption field of the socket and hcon QoS
according to the encryption parameter of the BIGInfo
advertising report event.

After that, the userspace is woken up, and the QoS of the
new PA sync socket can be read, to inspect the encryption
field and follow up accordingly.
