efcfcd5f2b Bluetooth: Fix bogus check for re-auth no supported with non-ssp
[ Upstream commit d03376c185926098cb4d668d6458801eb785c0a5 ]

This reverts 19f8def031bfa50c579149b200bfeeb919727b27
"Bluetooth: Fix auth_complete_evt for legacy units" which seems to be
working around a bug on a broken controller rather then any limitation
imposed by the Bluetooth spec, in fact if there ws not possible to
re-auth the command shall fail not succeed.

598c902649 netfilter: nf_tables: mark newset as dead on transaction abort
[ Upstream commit 08e4c8c5919fd405a4d709b4ba43d836894a26eb ]

If a transaction is aborted, we should mark the to-be-released NEWSET dead,
just like commit path does for DEL and DESTROYSET commands.

In both cases all remaining elements will be released via
set->ops->destroy().

The existing abort code does NOT post the actual release to the work queue.
Also the entire __nf_tables_abort() function is wrapped in gc_seq
begin/end pair.

Therefore, async gc worker will never try to release the pending set
elements, as gc sequence is always stale.

It might be possible to speed up transaction aborts via work queue too,
this would result in a race and a possible use-after-free.

So fix this before it becomes an issue.

48614d528b virtio/vsock: fix logic which reduces credit update messages
[ Upstream commit 93b80887668226180ea5f5349cc728ca6dc700ab ]

Add one more condition for sending credit update during dequeue from
stream socket: when number of bytes in the rx queue is smaller than
SO_RCVLOWAT value of the socket. This is actual for non-default value
of SO_RCVLOWAT (e.g. not 1) - idea is to "kick" peer to continue data
transmission, because we need at least SO_RCVLOWAT bytes in our rx
queue to wake up user for reading data (in corner case it is also
possible to stuck both tx and rx sides, this is why 'Fixes' is used).

[ Upstream commit bc8263083af60e7e57c6120edbc1f75d6c909a35 ]

Clang static checker warns:

drivers/net/wireless/realtek/rtlwifi/rtl8821ae/phy.c:184:49:
	The result of the left shift is undefined due to shifting by '32',
	which is greater or equal to the width of type 'u32'.
	[core.UndefinedBinaryOperatorResult]

If the value of the right operand is negative or is greater than or
equal to the width of the promoted left operand, the behavior is
undefined.[1][2]

For example, when using different gcc's compilation optimization options
(-O0 or -O2), the result of '(u32)data << 32' is different. One is 0, the
other is old value of data. Let _rtl8821ae_phy_calculate_bit_shift()'s
return value less than 32 to fix this problem. Warn if bitmask is zero.

ef75f3c56b net/ncsi: Fix netlink major/minor version numbers
[ Upstream commit 3084b58bfd0b9e4b5e034f31f31b42977db35f12 ]

The netlink interface for major and minor version numbers doesn't actually
return the major and minor version numbers.

It reports a u32 that contains the (major, minor, update, alpha1)
components as the major version number, and then alpha2 as the minor
version number.

For whatever reason, the u32 byte order was reversed (ntohl): maybe it was
assumed that the encoded value was a single big-endian u32, and alpha2 was
the minor version.

The correct way to get the supported NC-SI version from the network
controller is to parse the Get Version ID response as described in 8.4.44
of the NC-SI spec[1].

    Get Version ID Response Packet Format

              Bits
            +--------+--------+--------+--------+
     Bytes  | 31..24 | 23..16 | 15..8  | 7..0   |
    +-------+--------+--------+--------+--------+
    | 0..15 | NC-SI Header                      |
    +-------+--------+--------+--------+--------+
    | 16..19| Response code   | Reason code     |
    +-------+--------+--------+--------+--------+
    |20..23 | Major  | Minor  | Update | Alpha1 |
    +-------+--------+--------+--------+--------+
    |24..27 |         reserved         | Alpha2 |
    +-------+--------+--------+--------+--------+
    |            .... other stuff ....          |

The major, minor, and update fields are all binary-coded decimal (BCD)
encoded [2]. The spec provides examples below the Get Version ID response
format in section 8.4.44.1, but for practical purposes, this is an example
from a live network card:

    root@bmc:~# ncsi-util 0x15
    NC-SI Command Response:
    cmd: GET_VERSION_ID(0x15)
    Response: COMMAND_COMPLETED(0x0000)  Reason: NO_ERROR(0x0000)
    Payload length = 40

    20: 0xf1 0xf1 0xf0 0x00 <<<<<<<<< (major, minor, update, alpha1)
    24: 0x00 0x00 0x00 0x00 <<<<<<<<< (_, _, _, alpha2)

    28: 0x6d 0x6c 0x78 0x30
    32: 0x2e 0x31 0x00 0x00
    36: 0x00 0x00 0x00 0x00
    40: 0x16 0x1d 0x07 0xd2
    44: 0x10 0x1d 0x15 0xb3
    48: 0x00 0x17 0x15 0xb3
    52: 0x00 0x00 0x81 0x19

This should be parsed as "1.1.0".

"f" in the upper-nibble means to ignore it, contributing zero.

If both nibbles are "f", I think the whole field is supposed to be ignored.
Major and minor are "required", meaning they're not supposed to be "ff",
but the update field is "optional" so I think it can be ff. I think the
simplest thing to do is just set the major and minor to zero instead of
juggling some conditional logic or something.

bcd2bin() from "include/linux/bcd.h" seems to assume both nibbles are 0-9,
so I've provided a custom BCD decoding function.

Alpha1 and alpha2 are ISO/IEC 8859-1 encoded, which just means ASCII
characters as far as I can tell, although the full encoding table for
non-alphabetic characters is slightly different (I think).

I imagine the alpha fields are just supposed to be alphabetic characters,
but I haven't seen any network cards actually report a non-zero value for
either.

If people wrote software against this netlink behavior, and were parsing
the major and minor versions themselves from the u32, then this would
definitely break their code.

When looking up an element in LPM trie, the condition 'matchlen ==

than trie->max_prefixlen. Consequently all elements in the LPM trie will

[ Upstream commit a3c6f4f4d249cecaf2f34471aadbfb4f4ef57298 ]

When testing sahara sha256 speed performance with tcrypt (mode=404) on
imx53-qsrb board, multiple "Invalid numbers of src SG." errors are
reported. This was traced to sahara_walk_and_recalc() resizing req->src
and causing the subsequent dma_map_sg() call to fail.

Now that the previous commit fixed sahara_sha_hw_links_create() to take
into account the actual request size, rather than relying on sg->length
values, the resize operation is no longer necessary.

Therefore, remove sahara_walk_and_recalc() and simplify associated logic.

In persistent_ram_init_ecc(), on 64-bit arches DIV_ROUND_UP() will return
64-bit value since persistent_ram_zone::buffer_size has type size_t which
is derived from the 64-bit *unsigned long*, while the ecc_blocks variable
this value gets assigned to has (always 32-bit) *int* type.  Even if that
value fits into *int* type, an overflow is still possible when calculating
the size_t typed ecc_total variable further below since there's no cast to
any 64-bit type before multiplication.  Declaring the ecc_blocks variable
as *size_t* should fix this mess...

1bf4fe14e9 mtd: Fix gluebi NULL pointer dereference caused by ftl notifier
[ Upstream commit a43bdc376deab5fff1ceb93dca55bcab8dbdc1d6 ]

If both ftl.ko and gluebi.ko are loaded, the notifier of ftl
triggers NULL pointer dereference when trying to access
‘gluebi->desc’ in gluebi_read().

ubi_gluebi_init
  ubi_register_volume_notifier
    ubi_enumerate_volumes
      ubi_notify_all
        gluebi_notify    nb->notifier_call()
          gluebi_create
            mtd_device_register
              mtd_device_parse_register
                add_mtd_device
                  blktrans_notify_add   not->add()
                    ftl_add_mtd         tr->add_mtd()
                      scan_header
                        mtd_read
                          mtd_read_oob
                            mtd_read_oob_std
                              gluebi_read   mtd->read()
                                gluebi->desc - NULL

Detailed reproduction information available at the Link [1],

In the normal case, obtain gluebi->desc in the gluebi_get_device(),
and access gluebi->desc in the gluebi_read(). However,
gluebi_get_device() is not executed in advance in the
ftl_add_mtd() process, which leads to NULL pointer dereference.

The solution for the gluebi module is to run jffs2 on the UBI
volume without considering working with ftl or mtdblock [2].
Therefore, this problem can be avoided by preventing gluebi from
creating the mtdblock device after creating mtd partition of the
type MTD_UBIVOLUME.

36e19f8463 calipso: fix memory leak in netlbl_calipso_add_pass()
[ Upstream commit ec4e9d630a64df500641892f4e259e8149594a99 ]

If IPv6 support is disabled at boot (ipv6.disable=1),
the calipso_init() -> netlbl_calipso_ops_register() function isn't called,
and the netlbl_calipso_ops_get() function always returns NULL.
In this case, the netlbl_calipso_add_pass() function allocates memory
for the doi_def variable but doesn't free it with the calipso_doi_free().
