[ Upstream commit 0605d9fb411f3337482976842a3901d6c125d298 ]

New Allwinner's SPI controllers can support dual and quad SPI modes.
To enable one of these modes, we should set the corresponding bit in
the SUN6I_BURST_CTL_CNT_REG register. DRM (28 bits) for dual mode and
Quad_EN (29 bits) for quad transmission.

* [PATCH AUTOSEL 6.5 02/45] devlink: remove reload failed checks in params get/set callbacks

From: Jiri Pirko <jiri@nvidia.com>

[ Upstream commit 633d76ad01ad0321a1ace3e5cc4fed06753d7ac4 ]

The checks in question were introduced by:
commit 6b4db2e528f6 ("devlink: Fix use-after-free after a failed reload").
That fixed an issue of reload with mlxsw driver.

Back then, that was a valid fix, because there was a limitation
in place that prevented drivers from registering/unregistering params
when devlink instance was registered.

It was possible to do the fix differently by changing drivers to
register/unregister params in appropriate places making sure the ops
operate only on memory which is allocated and initialized. But that,
as a dependency, would require to remove the limitation mentioned above.

Eventually, this limitation was lifted by:
commit 1d18bb1a4ddd ("devlink: allow registering parameters after the instance")

Also, the alternative fix (which also fixed another issue) was done by:
commit 74cbc3c03c82 ("mlxsw: spectrum_acl_tcam: Move devlink param to TCAM code").

Therefore, the checks are no longer relevant. Each driver should make
sure to have the params registered only when the memory the ops
are working with is allocated and initialized.

So remove the checks.

From: Azeem Shaikh <azeemshaikh38@gmail.com>

[ Upstream commit babb80b3ecc6f40c962e13c654ebcd27f25ee327 ]

strlcpy() reads the entire source buffer first.
This read may exceed the destination size limit.
This is both inefficient and can lead to linear read
overflows if a source string is not NUL-terminated [1].
In an effort to remove strlcpy() completely [2], replace
strlcpy() here with strscpy().

Direct replacement is safe here since return value of -errno
is used to check for truncation instead of sizeof(dest).

From: Jisheng Zhang <jszhang@kernel.org>

[ Upstream commit 133466c3bbe171f826294161db203f7670bb30c8 ]

Currently, there are two major issues with stmmac driver statistics
First of all, statistics in stmmac_extra_stats, stmmac_rxq_stats
and stmmac_txq_stats are 32 bit variables on 32 bit platforms. This
can cause some stats to overflow after several minutes of
high traffic, for example rx_pkt_n, tx_pkt_n and so on.

Secondly, if HW supports multiqueues, there are frequent cacheline
ping pongs on some driver statistic vars, for example, normal_irq_n,
tx_pkt_n and so on. What's more, frequent cacheline ping pongs on
normal_irq_n happens in ISR, this makes the situation worse.

To improve the driver, we convert those statistics to 64 bit, implement
ndo_get_stats64 and update .get_ethtool_stats implementation
accordingly. We also use per-queue statistics where necessary to remove
the cacheline ping pongs as much as possible to make multiqueue
operations faster. Those statistics which are not possible to overflow
and not frequently updated are kept as is.

From: Jisheng Zhang <jszhang@kernel.org>

[ Upstream commit 133466c3bbe171f826294161db203f7670bb30c8 ]

Currently, there are two major issues with stmmac driver statistics
First of all, statistics in stmmac_extra_stats, stmmac_rxq_stats
and stmmac_txq_stats are 32 bit variables on 32 bit platforms. This
can cause some stats to overflow after several minutes of
high traffic, for example rx_pkt_n, tx_pkt_n and so on.

Secondly, if HW supports multiqueues, there are frequent cacheline
ping pongs on some driver statistic vars, for example, normal_irq_n,
tx_pkt_n and so on. What's more, frequent cacheline ping pongs on
normal_irq_n happens in ISR, this makes the situation worse.

To improve the driver, we convert those statistics to 64 bit, implement
ndo_get_stats64 and update .get_ethtool_stats implementation
accordingly. We also use per-queue statistics where necessary to remove
the cacheline ping pongs as much as possible to make multiqueue
operations faster. Those statistics which are not possible to overflow
and not frequently updated are kept as is.

[ Upstream commit 7aa529a69e92b9aff585e569d5003f7c15d8d60b ]

There is possibility that ice_eswitch_port_start_xmit might be
called while some resources are still not allocated which might
cause NULL pointer dereference. Fix this by checking if switchdev
configuration was finished.

[ Upstream commit 810e41cebb6c6e394f2068f839e1a3fc745a5dcc ]

When compiling with gcc 13.1 and CONFIG_FORTIFY_SOURCE=y,
I've noticed the following:

In function ‘fortify_memcpy_chk’,
    inlined from ‘ath_tx_complete_aggr’ at drivers/net/wireless/ath/ath9k/xmit.c:556:4,

    inlined from ‘ath_tx_count_frames’ at drivers/net/wireless/ath/ath9k/xmit.c:473:3,

In both cases, the compiler complains on:

memcpy(ba, &ts->ba_low, WME_BA_BMP_SIZE >> 3);

which is the legal way to copy both 'ba_low' and following 'ba_high'
members of 'struct ath_tx_status' at once (that is, issue one 8-byte
'memcpy()' for two 4-byte fields). Since the fortification logic seems
interprets this trick as an attempt to overread 4-byte 'ba_low', silence
relevant warnings by using the convenient 'struct_group()' quirk.

[ Upstream commit 061115fbfb2ce5870c9a004d68dc63138c07c782 ]

Smatch reports:

ath_pci_probe() warn: argument 4 to %lx specifier is cast from pointer
ath_ahb_probe() warn: argument 4 to %lx specifier is cast from pointer

Fix it by modifying %lx to %p in the printk format string.

Note that with this change, the pointer address will be printed as a
hashed value by default. This is appropriate because the kernel
should not leak kernel pointers to user space in an informational
message. If someone wants to see the real address for debugging
purposes, this can be achieved with the no_hash_pointers kernel option.

From: Dmitry Antipov <dmantipov@yandex.ru>

[ Upstream commit dcce94b80a954a8968ff29fafcfb066d6197fa9a ]

When compiling with gcc 13.1 and CONFIG_FORTIFY_SOURCE=y,
I've noticed the following:

In function ‘fortify_memcpy_chk’,
    inlined from ‘mwifiex_construct_tdls_action_frame’ at drivers/net/wireless/marvell/mwifiex/tdls.c:765:3,
    inlined from ‘mwifiex_send_tdls_action_frame’ at drivers/net/wireless/marvell/mwifiex/tdls.c:856:6:
./include/linux/fortify-string.h:529:25: warning: call to ‘__read_overflow2_field’
declared with attribute warning: detected read beyond size of field (2nd parameter);
maybe use struct_group()? [-Wattribute-warning]
  529 |                         __read_overflow2_field(q_size_field, size);
      |                         ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

The compiler actually complains on:

memmove(pos + ETH_ALEN, &mgmt->u.action.category,
	sizeof(mgmt->u.action.u.tdls_discover_resp));

and it happens because the fortification logic interprets this
as an attempt to overread 1-byte 'u.action.category' member of
'struct ieee80211_mgmt'. To silence this warning, it's enough
to pass an address of 'u.action' itself instead of an address
of its first member.

This also fixes an improper usage of 'sizeof()'. Since 'skb' is
extended with 'sizeof(mgmt->u.action.u.tdls_discover_resp) + 1'
bytes (where 1 is actually 'sizeof(mgmt->u.action.category)'),
I assume that the same number of bytes should be copied.

* [PATCH AUTOSEL 6.5 11/45] mt76: mt7921: don't assume adequate headroom for SDIO headers

From: Matt Whitlock <kernel@mattwhitlock.name>

[ Upstream commit 98c4d0abf5c478db1ad126ff0c187dbb84c0803c ]

mt7921_usb_sdio_tx_prepare_skb() calls mt7921_usb_sdio_write_txwi() and
mt7921_skb_add_usb_sdio_hdr(), both of which blindly assume that
adequate headroom will be available in the passed skb. This assumption
typically is satisfied when the skb was allocated in the net core for
transmission via the mt7921 netdev (although even that is only an
optimization and is not strictly guaranteed), but the assumption is
sometimes not satisfied when the skb originated in the receive path of
another netdev and was passed through to the mt7921, such as by the
bridge layer. Blindly prepending bytes to an skb is always wrong.

This commit introduces a call to skb_cow_head() before the call to
mt7921_usb_sdio_write_txwi() in mt7921_usb_sdio_tx_prepare_skb() to
ensure that at least MT_SDIO_TXD_SIZE + MT_SDIO_HDR_SIZE bytes can be
pushed onto the skb.

Without this fix, I can trivially cause kernel panics by bridging an
MT7921AU-based USB 802.11ax interface with an Ethernet interface on an
Intel Atom-based x86 system using its onboard RTL8169 PCI Ethernet
adapter and also on an ARM-based Raspberry Pi 1 using its onboard
SMSC9512 USB Ethernet adapter. Note that the panics do not occur in
every system configuration, as they occur only if the receiving netdev
leaves less headroom in its received skbs than the mt7921 needs for its
SDIO headers.

Here is an example stack trace of this panic on Raspberry Pi OS Lite
2023-02-21 running kernel 6.1.24+ [1]:

 skb_panic from skb_push+0x44/0x48
 skb_push from mt7921_usb_sdio_tx_prepare_skb+0xd4/0x190 [mt7921_common]
 mt7921_usb_sdio_tx_prepare_skb [mt7921_common] from mt76u_tx_queue_skb+0x94/0x1d0 [mt76_usb]

 __mt76_worker_fn [mt76] from kthread+0xbc/0xe0
 kthread from ret_from_fork+0x14/0x34

After this fix, bridging the mt7921 interface works fine on both of my
previously problematic systems.

[ Upstream commit 1ad8237e971630c66a1a6194491e0837b64d00e0 ]

When compiling with gcc 13.1 and CONFIG_FORTIFY_SOURCE=y,
I've noticed the following:

In function ‘fortify_memcpy_chk’,
    inlined from ‘wil_rx_crypto_check_edma’ at drivers/net/wireless/ath/wil6210/txrx_edma.c:566:2:
./include/linux/fortify-string.h:529:25: warning: call to ‘__read_overflow2_field’
declared with attribute warning: detected read beyond size of field (2nd parameter);
maybe use struct_group()? [-Wattribute-warning]
  529 |                         __read_overflow2_field(q_size_field, size);
      |                         ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

where the compiler complains on:

const u8 *pn;
...
pn = (u8 *)&st->ext.pn_15_0;
...
memcpy(cc->pn, pn, IEEE80211_GCMP_PN_LEN);

and:

In function ‘fortify_memcpy_chk’,
    inlined from ‘wil_rx_crypto_check’ at drivers/net/wireless/ath/wil6210/txrx.c:684:2:
./include/linux/fortify-string.h:529:25: warning: call to ‘__read_overflow2_field’
declared with attribute warning: detected read beyond size of field (2nd parameter);
maybe use struct_group()? [-Wattribute-warning]
  529 |                         __read_overflow2_field(q_size_field, size);
      |                         ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

where the compiler complains on:

const u8 *pn = (u8 *)&d->mac.pn_15_0;
...
memcpy(cc->pn, pn, IEEE80211_GCMP_PN_LEN);

In both cases, the fortification logic interprets 'memcpy()' as 6-byte
overread of 2-byte field 'pn_15_0' of 'struct wil_rx_status_extension'
and 'pn_15_0' of 'struct vring_rx_mac', respectively. To silence
these warnings, last two fields of the aforementioned structures
are grouped using 'struct_group_attr(pn, __packed' quirk.

From: John Watts <contact@jookia.org>

[ Upstream commit 8abb95250ae6af2d51993da8fcae18da2ce24cc4 ]

The controllers present in the D1 are extremely similar to the R40
and require the same reset quirks, but An extra quirk is needed to support
receiving packets.

From: Kuniyuki Iwashima <kuniyu@amazon.com>

[ Upstream commit 8936bf53a091ad6a34b480c22002f1cb2422ab38 ]

Commit df8fc4e934c1 ("kbuild: Enable -fstrict-flex-arrays=3") started
applying strict rules to standard string functions.

It does not work well with conventional socket code around each protocol-
specific sockaddr_XXX struct, which is cast from sockaddr_storage and has
a bigger size than fortified functions expect.  See these commits:

 commit 06d4c8a80836 ("af_unix: Fix fortify_panic() in unix_bind_bsd().")
 commit ecb4534b6a1c ("af_unix: Terminate sun_path when bind()ing pathname socket.")
 commit a0ade8404c3b ("af_packet: Fix warning of fortified memcpy() in packet_getname().")

We must cast the protocol-specific address back to sockaddr_storage
to call such functions.

However, in the case of getsockaddr(SO_PEERNAME), the rationale is a bit
unclear as the buffer is defined by char[128] which is the same size as
sockaddr_storage.

Let's use sockaddr_storage explicitly.

[ Upstream commit 8ad314da54c6dd223a6b6cc85019160aa842f659 ]

In ath12k_mac_op_hw_scan(), the return value of kzalloc() is directly
used in memcpy(), which may lead to a NULL pointer dereference on
failure of kzalloc().

Fix this bug by adding a check of arg.extraie.ptr.

* [PATCH AUTOSEL 6.5 17/45] wifi: ath12k: avoid array overflow of hw mode for preferred_hw_mode

From: Wen Gong <quic_wgong@quicinc.com>

[ Upstream commit 1e9b1363e2de1552ee4e3d74ac8bb43a194f1cb4 ]

Currently ath12k define WMI_HOST_HW_MODE_DBS_OR_SBS=5 as max hw mode
for enum wmi_host_hw_mode_config_type, it is also same for the array
ath12k_hw_mode_pri_map.

When tested with new version firmware/board data which support new
hw mode eMLSR mode with hw mode value 8, it leads overflow usage for
array ath12k_hw_mode_pri_map in function ath12k_wmi_hw_mode_caps(),
and then lead preferred_hw_mode changed to 8, and finally function
ath12k_pull_mac_phy_cap_svc_ready_ext() select the capability of hw
mode 8, but the capability of eMLSR mode report from firmware does
not support 2.4 GHz band for WCN7850, so finally 2.4 GHz band is
disabled.

Skip the hw mode which exceeds WMI_HOST_HW_MODE_MAX in function
ath12k_wmi_hw_mode_caps() helps to avoid array overflow, then the 2.4
GHz band will not be disabled.

This is to keep compatibility with newer version firmware/board data
files, this change is still needed after ath12k add eMLSR hw mode 8 in
array ath12k_hw_mode_pri_map and enum wmi_host_hw_mode_config_type,
because more hw mode maybe added in next firmware/board data version
e.g hw mode 9, then it will also lead new array overflow without this
change.

* [PATCH AUTOSEL 6.5 17/45] wifi: ath12k: avoid array overflow of hw mode for preferred_hw_mode

[ Upstream commit 1e9b1363e2de1552ee4e3d74ac8bb43a194f1cb4 ]

Currently ath12k define WMI_HOST_HW_MODE_DBS_OR_SBS=5 as max hw mode
for enum wmi_host_hw_mode_config_type, it is also same for the array
ath12k_hw_mode_pri_map.

When tested with new version firmware/board data which support new
hw mode eMLSR mode with hw mode value 8, it leads overflow usage for
array ath12k_hw_mode_pri_map in function ath12k_wmi_hw_mode_caps(),
and then lead preferred_hw_mode changed to 8, and finally function
ath12k_pull_mac_phy_cap_svc_ready_ext() select the capability of hw
mode 8, but the capability of eMLSR mode report from firmware does
not support 2.4 GHz band for WCN7850, so finally 2.4 GHz band is
disabled.

Skip the hw mode which exceeds WMI_HOST_HW_MODE_MAX in function
ath12k_wmi_hw_mode_caps() helps to avoid array overflow, then the 2.4
GHz band will not be disabled.

This is to keep compatibility with newer version firmware/board data
files, this change is still needed after ath12k add eMLSR hw mode 8 in
array ath12k_hw_mode_pri_map and enum wmi_host_hw_mode_config_type,
because more hw mode maybe added in next firmware/board data version
e.g hw mode 9, then it will also lead new array overflow without this
change.

Tested-on: WCN7850 hw2.0 PCI WLAN.HMT.1.0-03427-QCAHMTSWPL_V1.0_V2.0_SILICONZ-1.15378.4

From: xu xin <xu.xin16@zte.com.cn>

[ Upstream commit c67180efc507e04a87f22aa68bd7dd832db006b7 ]

For now, No matter what error pointer ip_neigh_for_gw() returns,
ip_finish_output2() always return -EINVAL, which may mislead the upper
users.

For exemple, an application uses sendto to send an UDP packet, but when the
neighbor table overflows, sendto() will get a value of -EINVAL, and it will
cause users to waste a lot of time checking parameters for errors.

Return the real errno instead of -EINVAL.

[ Upstream commit 1ded5e5a5931bb8b31e15b63b655fe232e3416b2 ]

IPV6_ADDRFORM socket option is evil, because it can change sock->ops
while other threads might read it. Same issue for sk->sk_family
being set to AF_INET.

Adding READ_ONCE() over sock->ops reads is needed for sockets
that might be impacted by IPV6_ADDRFORM.

Note that mptcp_is_tcpsk() can also overwrite sock->ops.

Adding annotations for all sk->sk_family reads will require
more patches :/

[ Upstream commit 9e47a758b70167c9301d2b44d2569f86c7796f2d ]

During NVMeTCP Authentication a controller can trigger a kernel
oops by specifying the 8192 bit Diffie Hellman group and passing
a correctly sized, but zeroed Diffie Hellamn value.
mpi_cmp_ui() was detecting this if the second parameter was 0,
but 1 is passed from dh_is_pubkey_valid(). This causes the null
pointer u->d to be dereferenced towards the end of mpi_cmp_ui()

[ Upstream commit 573ebae162111063eedc6c838a659ba628f66a0f ]

If hci_unregister_dev() frees the hci_dev object but hci_suspend_notifier
may still be accessing it, it can cause the program to crash.
Here's the call trace:
  <4>[102152.653246] Call Trace:

This patch holds the reference count of the hci_dev object while
processing it in hci_suspend_notifier to avoid potential crash
caused by the race condition.

From: Eric Dumazet <edumazet@google.com>

[ Upstream commit 8fe08d70a2b61b35a0a1235c78cf321e7528351f ]

sk_diag_put_flags(), netlink_setsockopt(), netlink_getsockopt()
and others use nlk->flags without correct locking.

Use set_bit(), clear_bit(), test_bit(), assign_bit() to remove
data-races.

[ Upstream commit 280db21e153d8810ce3b93640c63ae922bcb9e8e ]

Similar to the transmission of TPM responses, also the transmission of TPM
commands may become corrupted. Instead of aborting when detecting such
issues, try resending the command again.

[ Upstream commit 5ae4b0d8875caa44946e579420c7fd5740d58653 ]

Errata ERR010450 only shows up if voltage is 1.8V, but if the device is
supplied by 3v3 the errata can be ignored. So let's check for if quirk
SDHCI_QUIRK2_NO_1_8_V is defined or not before limiting the frequency.

[ Upstream commit 5ae4b0d8875caa44946e579420c7fd5740d58653 ]

Errata ERR010450 only shows up if voltage is 1.8V, but if the device is
supplied by 3v3 the errata can be ignored. So let's check for if quirk
SDHCI_QUIRK2_NO_1_8_V is defined or not before limiting the frequency.

In order to get alx stats altogether, alx_get_ethtool_stats() reads
beyond hw->stats.rx_ok. Fix this warning by directly copying hw->stats,
and refactor the unnecessarily complicated BUILD_BUG_ON btw.

From: Avraham Stern <avraham.stern@intel.com>

[ Upstream commit 057381ddac0593c6e4ca8f58732830d8542b9c4e ]

In case CSME holds the NIC and SAP connection is already established,
iwl_pcie_prepare_card_hw() during iwl_pci_probe() will fail
(which is fine since CSME will release the nic later when asked with
a SAP message). In this case tring to grab nic access to read the
crf ids will fail with a warning.
Avoid the warning by only trying to read the crf ids in case prepare
card succeeded.

From: "GONG, Ruiqi" <gongruiqi1@huawei.com>

[ Upstream commit a7ed3465daa240bdf01a5420f64336fee879c09d ]

When compiling with gcc 13 and CONFIG_FORTIFY_SOURCE=y, the following
warning appears:

In function ‘fortify_memcpy_chk’,
    inlined from ‘size_entry_mwt’ at net/bridge/netfilter/ebtables.c:2118:2:
./include/linux/fortify-string.h:592:25: error: call to ‘__read_overflow2_field’
declared with attribute warning: detected read beyond size of field (2nd parameter);
maybe use struct_group()? [-Werror=attribute-warning]
  592 |                         __read_overflow2_field(q_size_field, size);
      |                         ^~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

The compiler is complaining:

memcpy(&offsets[1], &entry->watchers_offset,
                       sizeof(offsets) - sizeof(offsets[0]));

where memcpy reads beyong &entry->watchers_offset to copy
{watchers,target,next}_offset altogether into offsets[]. Silence the
warning by wrapping these three up via struct_group().

If the AP uses our own address as its MLD address or BSSID, then
clearly something's wrong. Reject such connections so we don't
try and fail later.

leave, since that's just confusing. Since set/clear the
chandef state, that's a simple check.

[ Upstream commit 67dfa589aa8806c7959cbca2f4613b8d41c75a06 ]

When probing a client, first check if we have it, and then
check for the channel context, otherwise you can trigger
the warning there easily by probing when the AP isn't even
started yet. Since a client existing means the AP is also
operating, we can then keep the warning.

Also simplify the moved code a bit.

end after Address 1, such frames shouldn't be forwarded through
wmediumd or similar userspace, so require the full 3-address

[ Upstream commit 29d67fdebc42af6466d1909c60fdd1ef4f3e5240 ]

I hit a memory leak when testing bpf_program__set_attach_target().
Basically, set_attach_target() may allocate btf_vmlinux, for example,
when setting attach target for bpf_iter programs. But btf_vmlinux
is freed only in bpf_object_load(), which means if we only open
bpf object but not load it, setting attach target may leak
btf_vmlinux.

So let's free btf_vmlinux in bpf_object__close() anyway.

From: Rajat Soni <quic_rajson@quicinc.com>

[ Upstream commit afb522b36e76acaa9f8fc06d0a9742d841c47c16 ]

Currently when ath12k_dp_cc_desc_init() is called we allocate
memory to rx_descs and tx_descs. In ath12k_dp_cc_cleanup(), during
descriptor cleanup rx_descs and tx_descs memory is not freed.

This is cause of memory leak. These allocated memory should be
freed in ath12k_dp_cc_cleanup.

In ath12k_dp_cc_desc_init(), we can save base address of rx_descs
and tx_descs. In ath12k_dp_cc_cleanup(), we can free rx_descs and
tx_descs memory using their base address.

* [PATCH AUTOSEL 6.5 40/45] wifi: ath12k: Fix memory leak in rx_desc and tx_desc

From: Rajat Soni <quic_rajson@quicinc.com>

[ Upstream commit afb522b36e76acaa9f8fc06d0a9742d841c47c16 ]

Currently when ath12k_dp_cc_desc_init() is called we allocate
memory to rx_descs and tx_descs. In ath12k_dp_cc_cleanup(), during
descriptor cleanup rx_descs and tx_descs memory is not freed.

This is cause of memory leak. These allocated memory should be
freed in ath12k_dp_cc_cleanup.

In ath12k_dp_cc_desc_init(), we can save base address of rx_descs
and tx_descs. In ath12k_dp_cc_cleanup(), we can free rx_descs and
tx_descs memory using their base address.

[ Upstream commit d831e3612111d385e8629104af5429808ef26e25 ]

The quirks table was named "blacklist_table" which isn't a good
description for that table as devices detected using it weren't ignored
by the driver.

Rename the table to match what it actually does.

From: Wen Gong <quic_wgong@quicinc.com>

[ Upstream commit 2f5124e86ae74b7ba24c9ae2644107b750cbf38f ]

Currently the extraie length is directly used to allocate skb buffer. When
the length of skb is greater than the max message length which firmware
supports, error will happen in firmware side.

Hence add check for the skb length and drop extraie when overflow and
print a message.

From: Alan Stern <stern@rowland.harvard.edu>

[ Upstream commit 5d7cf67f72ae34d38e090bdfa673da4aefe4048e ]

A mouse that uses a USB connection is called a "USB mouse" device (or
"USB mouse" for short), not a "mouse USB" device.  By analogy, a WiFi
adapter that connects to the host computer via USB is a "USB wireless"
device, not a "wireless USB" device.  (The latter term more properly
refers to a defunct Wireless USB specification, which described a
technology for sending USB protocol messages over an ultra wideband
radio link.)

Similarly for a WiFi adapter card that plugs into a PCIe slot: It is a
"PCIe wireless" device, not a "wireless PCIe" device.

Rephrase the text in the kernel source where the word ordering is
wrong.

From: Alan Stern <stern@rowland.harvard.edu>

[ Upstream commit 5d7cf67f72ae34d38e090bdfa673da4aefe4048e ]

A mouse that uses a USB connection is called a "USB mouse" device (or
"USB mouse" for short), not a "mouse USB" device.  By analogy, a WiFi
adapter that connects to the host computer via USB is a "USB wireless"
device, not a "wireless USB" device.  (The latter term more properly
refers to a defunct Wireless USB specification, which described a
technology for sending USB protocol messages over an ultra wideband
radio link.)

Similarly for a WiFi adapter card that plugs into a PCIe slot: It is a
"PCIe wireless" device, not a "wireless PCIe" device.

Rephrase the text in the kernel source where the word ordering is
wrong.

From: Alan Stern <stern@rowland.harvard.edu>

[ Upstream commit 5d7cf67f72ae34d38e090bdfa673da4aefe4048e ]

A mouse that uses a USB connection is called a "USB mouse" device (or
"USB mouse" for short), not a "mouse USB" device.  By analogy, a WiFi
adapter that connects to the host computer via USB is a "USB wireless"
device, not a "wireless USB" device.  (The latter term more properly
refers to a defunct Wireless USB specification, which described a
technology for sending USB protocol messages over an ultra wideband
radio link.)

Similarly for a WiFi adapter card that plugs into a PCIe slot: It is a
"PCIe wireless" device, not a "wireless PCIe" device.

Rephrase the text in the kernel source where the word ordering is
wrong.

From: Alan Stern <stern@rowland.harvard.edu>

[ Upstream commit 5d7cf67f72ae34d38e090bdfa673da4aefe4048e ]

A mouse that uses a USB connection is called a "USB mouse" device (or
"USB mouse" for short), not a "mouse USB" device.  By analogy, a WiFi
adapter that connects to the host computer via USB is a "USB wireless"
device, not a "wireless USB" device.  (The latter term more properly
refers to a defunct Wireless USB specification, which described a
technology for sending USB protocol messages over an ultra wideband
radio link.)

Similarly for a WiFi adapter card that plugs into a PCIe slot: It is a
"PCIe wireless" device, not a "wireless PCIe" device.

Rephrase the text in the kernel source where the word ordering is
wrong.

From: Alan Stern <stern@rowland.harvard.edu>

[ Upstream commit 5d7cf67f72ae34d38e090bdfa673da4aefe4048e ]

A mouse that uses a USB connection is called a "USB mouse" device (or
"USB mouse" for short), not a "mouse USB" device.  By analogy, a WiFi
adapter that connects to the host computer via USB is a "USB wireless"
device, not a "wireless USB" device.  (The latter term more properly
refers to a defunct Wireless USB specification, which described a
technology for sending USB protocol messages over an ultra wideband
radio link.)

Similarly for a WiFi adapter card that plugs into a PCIe slot: It is a
"PCIe wireless" device, not a "wireless PCIe" device.

Rephrase the text in the kernel source where the word ordering is
wrong.

[ Upstream commit 2a6d50b50d6d589d43a90d6ca990b8b811e67701 ]

Recent discussions around default kptr "trustedness" led to changes such
as commit 6fcd486b3a0a ("bpf: Refactor RCU enforcement in the
verifier."). One of the conclusions of those discussions, as expressed
in code and comments in that patch, is that we'd like to move away from
'raw' PTR_TO_BTF_ID without some type flag or other register state
indicating trustedness. Although PTR_TRUSTED and PTR_UNTRUSTED flags mark
this state explicitly, the verifier currently considers trustedness
implied by other register state. For example, owning refs to graph
collection nodes must have a nonzero ref_obj_id, so they pass the
is_trusted_reg check despite having no explicit PTR_{UN}TRUSTED flag.
This patch makes trustedness of non-owning refs to graph collection
nodes explicit as well.

By definition, non-owning refs are currently trusted. Although the ref
has no control over pointee lifetime, due to non-owning ref clobbering
rules (see invalidate_non_owning_refs) dereferencing a non-owning ref is
safe in the critical section controlled by bpf_spin_lock associated with
its owning collection.

Note that the previous statement does not hold true for nodes with shared
ownership due to the use-after-free issue that this series is
addressing. True shared ownership was disabled by commit 7deca5eae833
("bpf: Disable bpf_refcount_acquire kfunc calls until race conditions are fixed"),
though, so the statement holds for now. Further patches in the series will change
the trustedness state of non-owning refs before re-enabling
bpf_refcount_acquire.

Let's add NON_OWN_REF type flag to BPF_REG_TRUSTED_MODIFIERS such that a
non-owning ref reg state would pass is_trusted_reg check. Somewhat
surprisingly, this doesn't result in any change to user-visible
functionality elsewhere in the verifier: graph collection nodes are all
marked MEM_ALLOC, which tends to be handled in separate codepaths from
"raw" PTR_TO_BTF_ID. Regardless, let's be explicit here and document the
current state of things before changing it elsewhere in the series.

[ Upstream commit 0816b8c6bf7fc87cec4273dc199e8f0764b9e7b1 ]

An earlier patch in the series ensures that the underlying memory of
nodes with bpf_refcount - which can have multiple owners - is not reused
until RCU grace period has elapsed. This prevents
use-after-free with non-owning references that may point to
recently-freed memory. While RCU read lock is held, it's safe to
dereference such a non-owning ref, as by definition RCU GP couldn't have
elapsed and therefore underlying memory couldn't have been reused.

From the perspective of verifier "trustedness" non-owning refs to
refcounted nodes are now trusted only in RCU CS and therefore should no
longer pass is_trusted_reg, but rather is_rcu_reg. Let's mark them
MEM_RCU in order to reflect this new state.

Is there any real reason to apply this commit to the -stable kernels?
I did not mark it that way when it was submitted, and it doesn't fix
any bugs.  In fact, aside from updating some module and device
description strings, all it does is change a bunch of comments.

Does that really fall under the -stable rules for acceptance?

Not really, this is just documentation, it should be dropped from the

This is an entire new driver - this is obviously entirely inappropriate
for stable.  I thought the output of this bot was supposed to be being
reviewed by humans before being sent out.  How did this make it to my
inbox?

Hi Sasha,

This patch cause a bug report recently[1], and I'm trying to fix it. So
could this back-port-to-stable tree be hold on until the fix is merged.

PS: If we want to apply this patch to stable tree, besides the above
fix, we also need to apply below preparation commit:
2eb85b750512 ("net: stmmac: don't clear network statistics in .ndo_open())

Thanks in advance

Hi Sasha,

This patch cause a bug report recently[1], and I'm trying to fix it. So
could this back-port-to-stable tree be hold on until the fix is merged.

PS: If we want to apply this patch to stable tree, besides the above
fix, we also need to apply below preparation commit:
2eb85b750512 ("net: stmmac: don't clear network statistics in .ndo_open())

Thanks in advance
