2022-12-19net: fec: properly guard irq coalesce setupRasmus Villemoes1-1/+2
commit 7e6303567ce3ca506e4a2704e4baa86f1d8bde02 upstream. Prior to the Fixes: commit, the initialization code went through the same fec_enet_set_coalesce() function as used by ethtool, and that function correctly checks whether the current variant has support for irq coalescing. Now that the initialization code instead calls fec_enet_itr_coal_set() directly, that call needs to be guarded by a check for the FEC_QUIRK_HAS_COALESCE bit.

2022-12-19ASoC: ops: Correct bounds check for second channel on SX controlsCharles Keepax1-4/+3
commit f33bcc506050f89433a52a3052054d4ebd37b1c1 upstream. Currently the check against the max value for the control is being applied after the value has had the minimum applied and been masked. But the max value simply indicates the number of volume levels on an SX control, and as such should just be applied on the raw value.

2022-12-19perf: Fix perf_pending_task() UaFPeter Zijlstra1-4/+13
[ Upstream commit 517e6a301f34613bff24a8e35b5455884f2d83d8 ] Per syzbot it is possible for perf_pending_task() to run after the event is free()'d. There are two related but distinct cases: - the task_work was already queued before destroying the event; - destroying the event itself queues the task_work. The first cannot be solved using task_work_cancel() since perf_release() itself might be called from a task_work (____fput), which means the current->task_works list is already empty and task_work_cancel() won't be able to find the perf_pending_task() entry. The simplest alternative is extending the perf_event lifetime to cover the task_work. The second is just silly, queueing a task_work while you know the event is going away makes no sense and is easily avoided by re-arranging how the event is marked STATE_DEAD and ensuring it goes through STATE_OFF on the way down.

2022-12-19net: fec: don't reset irq coalesce settings to defaults on "ip link up"Rasmus Villemoes1-16/+6
[ Upstream commit df727d4547de568302b0ed15b0d4e8a469bdb456 ] Currently, when a FEC device is brought up, the irq coalesce settings are reset to their default values (1000us, 200 frames). That's unexpected, and breaks for example use of an appropriate .link file to make systemd-udev apply the desired settings (https://www.freedesktop.org/software/systemd/man/systemd.link.html), or any other method that would do a one-time setup during early boot. Refactor the code so that fec_restart() instead uses fec_enet_itr_coal_set(), which simply applies the settings that are stored in the private data, and initialize that private data with the default values.

Address this by partially reverting commit 4919d3eb2ec0 so that cmos_wake_setup() is called before cmos_do_probe() again and moving the rtc_wake_setup() invocation from cmos_wake_setup() directly to the callers of cmos_do_probe() where it will happen after a successful completion of the latter.

2022-12-19rtc: cmos: Fix event handler registration ordering issueRafael J. Wysocki1-10/+19
commit 4919d3eb2ec0ee364f7e3cf2d99646c1b224fae8 upstream. Because acpi_install_fixed_event_handler() enables the event automatically on success, it is incorrect to call it before the handler routine passed to it is ready to handle events. Unfortunately, the rtc-cmos driver does exactly the incorrect thing by calling cmos_wake_setup(), which passes rtc_handler() to acpi_install_fixed_event_handler(), before cmos_do_probe(), because rtc_handler() uses dev_get_drvdata() to get to the cmos object pointer and the driver data pointer is only populated in cmos_do_probe(). This leads to a NULL pointer dereference in rtc_handler() on boot if the RTC fixed event happens to be active at the init time. To address this issue, change the initialization ordering of the driver so that cmos_wake_setup() is always called after a successful cmos_do_probe() call. While at it, change cmos_pnp_probe() to call cmos_do_probe() after the initial if () statement used for computing the IRQ argument to be passed to cmos_do_probe() which is cleaner than calling it in each branch of that if () (local variable "irq" can be of type int, because it is passed to that function as an argument of type int). Note that commit 6492fed7d8c9 ("rtc: rtc-cmos: Do not check ACPI_FADT_LOW_POWER_S0") caused this issue to affect a larger number of systems, because previously it only affected systems with ACPI_FADT_LOW_POWER_S0 set, but it is present regardless of that commit.

2022-12-14net: mvneta: Fix an out of bounds checkDan Carpenter1-4/+1
[ Upstream commit cdd97383e19d4afe29adc3376025a15ae3bab3a3 ] In an earlier commit, I added a bounds check to prevent an out of bounds read and a WARN(). On further discussion and consideration that check was probably too aggressive. Instead of returning -EINVAL, a better fix would be to just prevent the out of bounds read but continue the process. Background: The value of "pp->rxq_def" is a number between 0-7 by default, or even higher depending on the value of "rxq_number", which is a module parameter. If the value is more than the number of available CPUs then it will trigger the WARN() in cpu_max_bits_warn().

[ Upstream commit 5f4d487d01ff5349da38f7a09ca36bf6aa2e29fb ] At least the GPY215B and GPY215C has a bug where it is still driving the interrupt line (MDINT) even after the interrupt status register is read and its bits are cleared. This will cause an interrupt storm. Although the MDINT is multiplexed with a GPIO pin and theoretically we could switch the pinmux to GPIO input mode, this isn't possible because the access to this register will stall exactly as long as the interrupt line is asserted. We exploit this very fact and just read a random internal register in our interrupt handler. This way, it will be delayed until the external interrupt line is released and an interrupt storm is avoided. The internal register access via the mailbox was deduced by looking at the downstream PHY API because the datasheet doesn't mention any of this.

[ Upstream commit 87a39882b5ab3127700ac4b9277608075f98eda2 ] The ethernet-controller dt-schema, mostly pushed forward by Linux, has the "internal" PHY mode for denoting MAC connections to an internal PHY. U-Boot may provide device tree blobs where this phy-mode is specified, so make the Linux driver accept them. It appears that the current behavior with phy-mode = "internal" was introduced when mv88e6xxx started reporting supported_interfaces to phylink. Prior to that, I don't think it would have any issues accepting this phy-mode.

2022-12-14tipc: call tipc_lxc_xmit without holding node_read_lockXin Long1-3/+9
[ Upstream commit 88956177db179e4eba7cd590971961857d1565b8 ] When sending packets between nodes in netns, it calls tipc_lxc_xmit() for peer node to receive the packets where tipc_sk_mcast_rcv()/tipc_sk_rcv() might be called, and it's pretty much like in tipc_rcv(). Currently the local 'node rw lock' is held during calling tipc_lxc_xmit() to protect the peer_net not being freed by another thread. However, when receiving these packets, tipc_node_add_conn() might be called where the peer 'node rw lock' is acquired. Then a dead lock warning is triggered by lockdep detector, although it is not a real dead lock: WARNING: possible recursive locking detected -------------------------------------------- conn_server/1086 is trying to acquire lock: ffff8880065cb020 (&n->lock#2){++--}-{2:2}, \ at: tipc_node_add_conn.cold.76+0xaa/0x211 [tipc] but task is already holding lock: ffff8880065cd020 (&n->lock#2){++--}-{2:2}, \ at: tipc_node_xmit+0x285/0xb30 [tipc] other info that might help us debug this: Possible unsafe locking scenario: CPU0 ---- lock(&n->lock#2); lock(&n->lock#2); *** DEADLOCK *** May be due to missing lock nesting notation 4 locks held by conn_server/1086: #0: ffff8880036d1e40 (sk_lock-AF_TIPC){+.+.}-{0:0}, \ at: tipc_accept+0x9c0/0x10b0 [tipc] #1: ffff8880036d5f80 (sk_lock-AF_TIPC/1){+.+.}-{0:0}, \ at: tipc_accept+0x363/0x10b0 [tipc] #2: ffff8880065cd020 (&n->lock#2){++--}-{2:2}, \ at: tipc_node_xmit+0x285/0xb30 [tipc] #3: ffff888012e13370 (slock-AF_TIPC){+...}-{2:2}, \ at: tipc_sk_rcv+0x2da/0x1b40 [tipc] Call Trace: <TASK> dump_stack_lvl+0x44/0x5b __lock_acquire.cold.77+0x1f2/0x3d7 lock_acquire+0x1d2/0x610 _raw_write_lock_bh+0x38/0x80 tipc_node_add_conn.cold.76+0xaa/0x211 [tipc] tipc_sk_finish_conn+0x21e/0x640 [tipc] tipc_sk_filter_rcv+0x147b/0x3030 [tipc] tipc_sk_rcv+0xbb4/0x1b40 [tipc] tipc_lxc_xmit+0x225/0x26b [tipc] tipc_node_xmit.cold.82+0x4a/0x102 [tipc] __tipc_sendstream+0x879/0xff0 [tipc] tipc_accept+0x966/0x10b0 [tipc] do_accept+0x37d/0x590 This patch avoids this warning by not holding the 'node rw lock' before calling tipc_lxc_xmit(). As to protect the 'peer_net', rcu_read_lock() should be enough, as in cleanup_net() when freeing the netns, it calls synchronize_rcu() before the free is continued. Also since tipc_lxc_xmit() is like the RX path in tipc_rcv(), it makes sense to call it under rcu_read_lock(). Note that the right lock order must be: rcu_read_lock(); tipc_node_read_lock(n); tipc_node_read_unlock(n); tipc_lxc_xmit(); rcu_read_unlock(); instead of: tipc_node_read_lock(n); rcu_read_lock(); tipc_node_read_unlock(n); tipc_lxc_xmit(); rcu_read_unlock(); and we have to call tipc_node_read_lock/unlock() twice in tipc_node_xmit().

2022-12-14ipv4: Fix incorrect route flushing when table ID 0 is usedIdo Schimmel2-0/+13
[ Upstream commit c0d999348e01df03e0a7f550351f3907fabbf611 ] Cited commit added the table ID to the FIB info structure, but did not properly initialize it when table ID 0 is used. This can lead to a route in the default VRF with a preferred source address not being flushed when the address is deleted. Consider the following example: # ip address add dev dummy1 192.0.2.1/28 # ip address add dev dummy1 192.0.2.17/28 # ip route add 198.51.100.0/24 via 192.0.2.2 src 192.0.2.17 metric 100 # ip route add table 0 198.51.100.0/24 via 192.0.2.2 src 192.0.2.17 metric 200 # ip route show 198.51.100.0/24 198.51.100.0/24 via 192.0.2.2 dev dummy1 src 192.0.2.17 metric 100 198.51.100.0/24 via 192.0.2.2 dev dummy1 src 192.0.2.17 metric 200 Both routes are installed in the default VRF, but they are using two different FIB info structures. One with a metric of 100 and table ID of 254 (main) and one with a metric of 200 and table ID of 0. Therefore, when the preferred source address is deleted from the default VRF, the second route is not flushed: # ip address del dev dummy1 192.0.2.17/28 # ip route show 198.51.100.0/24 198.51.100.0/24 via 192.0.2.2 dev dummy1 src 192.0.2.17 metric 200 Fix by storing a table ID of 254 instead of 0 in the route configuration structure.

[ Upstream commit cb37617687f2bfa5b675df7779f869147c9002bd ] There is warning report about of_node refcount leak while probing mdio device: OF: ERROR: memory leak, expected refcount 1 instead of 2, of_node_get()/of_node_put() unbalanced - destroy cset entry: attach overlay node /spi/soc@0/mdio@710700c0/ethernet@4 In of_mdiobus_register_device(), we increase fwnode refcount by fwnode_handle_get() before associating the of_node with mdio device, but it has never been decreased in normal path. Since that, in mdio_device_release(), it needs to call fwnode_handle_put() in addition instead of calling kfree() directly. After above, just calling mdio_device_free() in the error handle path of of_mdiobus_register_device() is enough to keep the refcount balanced.
