[ Upstream commit 16c6c35c03 ]
While processing the monitor destination ring, MSDUs are reaped from the
link descriptor based on the corresponding buf_id.
However, sometimes the driver cannot obtain a valid buffer corresponding
to the buf_id received from the hardware. This causes an infinite loop
in the destination processing, resulting in a kernel crash.
kernel log:
ath11k_pci 0000:58:00.0: data msdu_pop: invalid buf_id 309
ath11k_pci 0000:58:00.0: data dp_rx_monitor_link_desc_return failed
ath11k_pci 0000:58:00.0: data msdu_pop: invalid buf_id 309
ath11k_pci 0000:58:00.0: data dp_rx_monitor_link_desc_return failed
Fix this by skipping the problematic buf_id and reaping the next entry,
replacing the break with the next MSDU processing.

commit 5a4391bdc6 upstream.
Fix similar memory leak as in commit 7352e1d593 ("can: gs_usb:
gs_usb_receive_bulk_callback(): fix URB memory leak").
In esd_usb_open(), the URBs for USB-in transfers are allocated, added to
the dev->rx_submitted anchor and submitted. In the complete callback
esd_usb_read_bulk_callback(), the URBs are processed and resubmitted. In
esd_usb_close() the URBs are freed by calling
usb_kill_anchored_urbs(&dev->rx_submitted).
However, this does not take into account that the USB framework unanchors
the URB before the complete function is called. This means that once an
in-URB has been completed, it is no longer anchored and is ultimately not
released in esd_usb_close().
Fix the memory leak by anchoring the URB in the
esd_usb_read_bulk_callback() to the dev->rx_submitted anchor.

commit 4f431d88ea upstream.
The struct ieee80211_vif contains trailing space for vif driver data,
when struct ieee80211_vif is allocated, the total memory size that is
allocated is sizeof(struct ieee80211_vif) + size of vif driver data.
The size of vif driver data is set by each WiFi driver as needed.
The RSI911x driver does not set vif driver data size, no trailing space
for vif driver data is therefore allocated past struct ieee80211_vif .
The RSI911x driver does however use the vif driver data to store its
vif driver data structure "struct vif_priv". An access to vif->drv_priv
leads to access out of struct ieee80211_vif bounds and corruption of
some memory.
In case of the failure observed locally, rsi_mac80211_add_interface()
would write struct vif_priv *vif_info = (struct vif_priv *)vif->drv_priv;
vif_info->vap_id = vap_idx. This write corrupts struct fq_tin member
struct list_head new_flows . The flow = list_first_entry(head, struct
fq_flow, flowchain); in fq_tin_reset() then reports non-NULL bogus
address, which when accessed causes a crash.
The trigger is very simple, boot the machine with init=/bin/sh , mount
devtmpfs, sysfs, procfs, and then do "ip link set wlan0 up", "sleep 1",
"ip link set wlan0 down" and the crash occurs.
Fix this by setting the correct size of vif driver data, which is the
size of "struct vif_priv", so that memory is allocated and the driver
can store its driver data in it, instead of corrupting memory around
it.

When the parameter pmac_id_valid argument of be_cmd_get_mac_from_list() is
set to false, the driver may request the PMAC_ID from the firmware of the
network card, and this function will store that PMAC_ID at the provided
address pmac_id. This is the contract of this function.
However, there is a location within the driver where both
pmac_id_valid == false and pmac_id == NULL are being passed. This could
result in dereferencing a NULL pointer.
To resolve this issue, it is necessary to pass the address of a stub
variable to the function.

[ Upstream commit c7159e960f ]
The usbnet driver initializes net->max_mtu to ETH_MAX_MTU before calling
the device's bind() callback. When the bind() callback sets
dev->hard_mtu based the device's actual capability (from CDC Ethernet's
wMaxSegmentSize descriptor), max_mtu is never updated to reflect this
hardware limitation).
This allows userspace (DHCP or IPv6 RA) to configure MTU larger than the
device can handle, leading to silent packet drops when the backend sends
packet exceeding the device's buffer size.
Fix this by limiting net->max_mtu to the device's hard_mtu after the
bind callback returns.

Make the addrs_lock be per port, not per ipvlan dev.
Initial code seems to be written in the assumption,
that any address change must occur under RTNL.
But it is not so for the case of IPv6. So
1) Introduce per-port addrs_lock.
2) It was needed to fix places where it was forgotten
to take lock (ipvlan_open/ipvlan_close)
This appears to be a very minor problem though.
Since it's highly unlikely that ipvlan_add_addr() will
be called on 2 CPU simultaneously. But nevertheless,
this could cause:
1) False-negative of ipvlan_addr_busy(): one interface
iterated through all port->ipvlans + ipvlan->addrs
under some ipvlan spinlock, and another added IP
under its own lock. Though this is only possible
for IPv6, since looks like only ipvlan_addr6_event() can be
called without rtnl_lock.
2) Race since ipvlan_ht_addr_add(port) is called under
different ipvlan->addrs_lock locks
This should not affect performance, since add/remove IP
is a rare situation and spinlock is not taken on fast
paths.

[ Upstream commit 79a6d1bfe1 ]
In commit 7352e1d593 ("can: gs_usb: gs_usb_receive_bulk_callback(): fix
URB memory leak"), the URB was re-anchored before usb_submit_urb() in
gs_usb_receive_bulk_callback() to prevent a leak of this URB during
cleanup.
However, this patch did not take into account that usb_submit_urb() could
fail. The URB remains anchored and
usb_kill_anchored_urbs(&parent->rx_submitted) in gs_can_close() loops
infinitely since the anchor list never becomes empty.
To fix the bug, unanchor the URB when an usb_submit_urb() error occurs,
also print an info message.

[ Upstream commit 7d7dbafefb ]
The SR9700 chip sends more than one packet in a USB transaction,
like the DM962x chips can optionally do, but the dm9601 driver does not
support this mode, and the hardware does not have the DM962x
MODE_CTL register to disable it, so this driver drops packets on SR9700
devices. The sr9700 driver correctly handles receiving more than one
packet per transaction.
While the dm9601 driver could be improved to handle this, the easiest
way to fix this issue in the short term is to remove the SR9700 device
ID from the dm9601 driver so the sr9700 driver is always used. This
device ID should not have been in more than one driver to begin with.
The "Fixes" commit was chosen so that the patch is automatically
included in all kernels that have the sr9700 driver, even though the
issue affects dm9601.

[ Upstream commit 6990dc392a ]
The current HW bug workaround checks the TXTT_0 ready bit first,
then reads TXSTMPL_0 twice (before and after reading TXSTMPH_0)
to detect whether a new timestamp was captured by timestamp
register 0 during the workaround.
This sequence has a race: if a new timestamp is captured after
checking the TXTT_0 bit but before the first TXSTMPL_0 read, the
detection fails because both the "old" and "new" values come from
the same timestamp.
Fix by reading TXSTMPL_0 first to establish a baseline, then
checking the TXTT_0 bit. This ensures any timestamp captured
during the race window will be detected.
Old sequence:
1. Check TXTT_0 ready bit
2. Read TXSTMPL_0 (baseline)
3. Read TXSTMPH_0 (interrupt workaround)
4. Read TXSTMPL_0 (detect changes vs baseline)
New sequence:
1. Read TXSTMPL_0 (baseline)
2. Check TXTT_0 ready bit
3. Read TXSTMPH_0 (interrupt workaround)
4. Read TXSTMPL_0 (detect changes vs baseline)

[ Upstream commit 41a9a6826f ]
The Multi-queue Priority (MQPRIO) and Earliest TxTime First (ETF) offloads
utilize the Time Sensitive Networking (TSN) Tx mode. This mode is always
coupled to IEEE 802.1Qbv time aware shaper (Qbv). Therefore, the driver
sets a default Qbv schedule of all gates opened and a cycle time of
1s. This schedule is set during probe.
However, the following sequence of events lead to Tx issues:
- Boot a dual core system
igc_probe():
igc_tsn_clear_schedule():
-> Default Schedule is set
Note: At this point the driver has allocated two Tx/Rx queues, because
there are only two CPUs.
- ethtool -L enp3s0 combined 4
igc_ethtool_set_channels():
igc_reinit_queues()
-> Default schedule is gone, per Tx ring start and end time are zero
- tc qdisc replace dev enp3s0 handle 100 parent root mqprio \
num_tc 4 map 3 3 2 2 0 1 1 1 3 3 3 3 3 3 3 3 \

igc_tsn_offload_apply():
igc_tsn_enable_offload():
-> Writes zeros to IGC_STQT(i) and IGC_ENDQT(i), causing Tx to stall/fail
Therefore, restore the default Qbv schedule after changing the number of
channels.
Furthermore, add a restriction to not allow queue reconfiguration when
TSN/Qbv is enabled, because it may lead to inconsistent states.

commit 7352e1d593 upstream.
In gs_can_open(), the URBs for USB-in transfers are allocated, added to the
parent->rx_submitted anchor and submitted. In the complete callback
gs_usb_receive_bulk_callback(), the URB is processed and resubmitted. In
gs_can_close() the URBs are freed by calling
usb_kill_anchored_urbs(parent->rx_submitted).
However, this does not take into account that the USB framework unanchors
the URB before the complete function is called. This means that once an
in-URB has been completed, it is no longer anchored and is ultimately not
released in gs_can_close().
Fix the memory leak by anchoring the URB in the

This patch fixes the edge case behavior on ifup/ifdown and
linking/unlinking two netdevsim interfaces:
1. unlink two interfaces netdevsim1 and netdevsim2
2. ifdown netdevsim1
3. ifup netdevsim1
4. link two interfaces netdevsim1 and netdevsim2
5. (Now two interfaces are linked in terms of netdevsim peer, but
carrier state of the two interfaces remains DOWN.)
This inconsistent behavior is caused by the current implementation,
which only cares about the "link, then ifup" order, not "ifup, then
link" order. This patch fixes the inconsistency by calling
netif_carrier_on() when two netdevsim interfaces are linked.
This patch fixes buggy behavior on NetworkManager-based systems which
causes the netdevsim test to fail with the following error:

MTU rounded up to the nearest power of 2. For example, ARM systems with
a 64K page size and an mtu of 9000 will set the Rx buffer size to 16K,
which will cause the config Rx queues message to fail.
