I.e. EAE Arcnet cards have a PLX rotary coder, which sets the first decimal, ensuring unique devices names. This patch adds two new card feature flags to indicate which cards support LEDs and the PLX rotary coder. For EAE based cards the names still depend on the PLX rotary coder (untested, since missing EAE hardware). For Sohard based cards, this patch will result in devices being called arc0, arc1, ... (tested).

2023-12-04r8152: Add RTL8152_INACCESSIBLE checks to more loopsDouglas Anderson
Previous commits added checks for RTL8152_INACCESSIBLE in the loops in the driver. There are still a few more that keep tripping the driver up in error cases and make things take longer than they should. Add those in. All the loops that are part of this commit existed in some form or another since the r8152 driver was first introduced, though RTL8152_INACCESSIBLE was known as RTL8152_UNPLUG before commit 715f67f33af4 ("r8152: Rename RTL8152_UNPLUG to RTL8152_INACCESSIBLE") Fixes: ac718b69301c ("net/usb: new driver for RTL8152") Reviewed-by: Grant Grundler <grundler@chromium.org> Signed-off-by: Douglas Anderson <dianders@chromium.org> Acked-by: Hayes Wang <hayeswang@realtek.com> Signed-off-by: David S.

2023-12-04r8152: Hold the rtnl_lock for all of resetDouglas Anderson
As of commit d9962b0d4202 ("r8152: Block future register access if register access fails") there is a race condition that can happen between the USB device reset thread and napi_enable() (not) getting called during rtl8152_open(). Specifically: * While rtl8152_open() is running we get a register access error that's _not_ -ENODEV and queue up a USB reset. * rtl8152_open() exits before calling napi_enable() due to any reason (including usb_submit_urb() returning an error). In that case: * Since the USB reset is perform in a separate thread asynchronously, it can run at anytime USB device lock is not held - even before rtl8152_open() has exited with an error and caused __dev_open() to clear the __LINK_STATE_START bit. * The rtl8152_pre_reset() will notice that the netif_running() returns true (since __LINK_STATE_START wasn't cleared) so it won't exit early. * rtl8152_pre_reset() will then hang in napi_disable() because napi_enable() was never called. We can fix the race by making sure that the r8152 reset routines don't run at the same time as we're opening the device. Specifically we need the reset routines in their entirety rely on the return value of netif_running(). The only way to reliably depend on that is for them to hold the rntl_lock() mutex for the duration of reset. Grabbing the rntl_lock() mutex for the duration of reset seems like a long time, but reset is not expected to be common and the rtnl_lock() mutex is already held for long durations since the core grabs it around the open/close calls.

2023-12-02r8169: fix rtl8125b PAUSE frames blasting when suspendedChunHao Lin
When FIFO reaches near full state, device will issue pause frame. If pause slot is enabled(set to 1), in this time, device will issue pause frame only once. But if pause slot is disabled(set to 0), device will keep sending pause frames until FIFO reaches near empty state. When pause slot is disabled, if there is no one to handle receive packets, device FIFO will reach near full state and keep sending pause frames. That will impact entire local area network. This issue can be reproduced in Chromebox (not Chromebook) in developer mode running a test image (and v5.10 kernel): 1) ping -f $CHROMEBOX (from workstation on same local network) 2) run "powerd_dbus_suspend" from command line on the $CHROMEBOX 3) ping $ROUTER (wait until ping fails from workstation) Takes about ~20-30 seconds after step 2 for the local network to stop working. Fix this issue by enabling pause slot to only send pause frame once when FIFO reaches near full state.

2023-12-01net/tg3: fix race condition in tg3_reset_task()Thinh Tran
When an EEH error is encountered by a PCI adapter, the EEH driver modifies the PCI channel's state as shown below: enum { /* I/O channel is in normal state */ pci_channel_io_normal = (__force pci_channel_state_t) 1, /* I/O to channel is blocked */ pci_channel_io_frozen = (__force pci_channel_state_t) 2, /* PCI card is dead */ pci_channel_io_perm_failure = (__force pci_channel_state_t) 3, }; If the same EEH error then causes the tg3 driver's transmit timeout logic to execute, the tg3_tx_timeout() function schedules a reset task via tg3_reset_task_schedule(), which may cause a race condition between the tg3 and EEH driver as both attempt to recover the HW via a reset action. EEH driver gets error event --> eeh_set_channel_state() and set device to one of error state above scheduler: tg3_reset_task() get returned error from tg3_init_hw() --> dev_close() shuts down the interface tg3_io_slot_reset() and tg3_io_resume() fail to reset/resume the device To resolve this issue, we avoid the race condition by checking the PCI channel state in the tg3_reset_task() function and skip the tg3 driver initiated reset when the PCI channel is not in the normal state. (The driver has no access to tg3 device registers at this point and cannot even complete the reset task successfully without external assistance.) We'll leave the reset procedure to be managed by the EEH driver which calls the tg3_io_error_detected(), tg3_io_slot_reset() and tg3_io_resume() functions as appropriate. Adding the same checking in tg3_dump_state() to avoid dumping all device registers when the PCI channel is not in the normal state.

2023-11-30net: ravb: Keep reverse order of operations in ravb_remove()Claudiu Beznea
On RZ/G3S SMARC Carrier II board having RGMII connections b/w Ethernet MACs and PHYs it has been discovered that doing unbind/bind for ravb driver in a loop leads to wrong speed and duplex for Ethernet links and broken connectivity (the connectivity cannot be restored even with bringing interface down/up). Before doing unbind/bind the Ethernet interfaces were configured though systemd. The sh instructions used to do unbind/bind were: $ cd /sys/bus/platform/drivers/ravb/ $ while :; do echo 11c30000.ethernet > unbind ; \ echo 11c30000.ethernet > bind; done It has been discovered that there is a race b/w IOCTLs initialized by systemd at the response of success binding and the "ravb_write(ndev, CCC_OPC_RESET, CCC)" call in ravb_remove() as follows: 1/ as a result of bind success the user space open/configures the interfaces tough an IOCTL; the following stack trace has been identified on RZ/G3S: Call trace: dump_backtrace+0x9c/0x100 show_stack+0x20/0x38 dump_stack_lvl+0x48/0x60 dump_stack+0x18/0x28 ravb_open+0x70/0xa58 __dev_open+0xf4/0x1e8 __dev_change_flags+0x198/0x218 dev_change_flags+0x2c/0x80 devinet_ioctl+0x640/0x708 inet_ioctl+0x1e4/0x200 sock_do_ioctl+0x50/0x108 sock_ioctl+0x240/0x358 __arm64_sys_ioctl+0xb0/0x100 invoke_syscall+0x50/0x128 el0_svc_common.constprop.0+0xc8/0xf0 do_el0_svc+0x24/0x38 el0_svc+0x34/0xb8 el0t_64_sync_handler+0xc0/0xc8 el0t_64_sync+0x190/0x198 2/ this call may execute concurrently with ravb_remove() as the unbind/bind operation was executed in a loop 3/ if the operation mode is changed to RESET (through ravb_write(ndev, CCC_OPC_RESET, CCC) call in ravb_remove()) while the above ravb_open() is in progress it may lead to MAC (or PHY, or MAC-PHY connection, the right point hasn't been identified at the moment) to be broken, thus the Ethernet connectivity fails to restore. The simple fix for this is to move ravb_write(ndev, CCC_OPC_RESET, CCC)) after unregister_netdev() to avoid resetting the controller while the netdev interface is still registered. To avoid future issues in ravb_remove(), the patch follows the proper order of operations in ravb_remove(): reverse order compared with ravb_probe(). This avoids described races as the IOCTLs as well as unregister_netdev() (called now at the beginning of ravb_remove()) calls rtnl_lock() before continuing and IOCTLs check (though devinet_ioctl()) if device is still registered just after taking the lock: int devinet_ioctl(struct net *net, unsigned int cmd, struct ifreq *ifr) { // ... rtnl_lock(); ret = -ENODEV; dev = __dev_get_by_name(net, ifr->ifr_name); if (!dev) goto done; // ... done: rtnl_unlock(); out: return ret; } Fixes: c156633f1353 ("Renesas Ethernet AVB driver proper") Reviewed-by: Sergey Shtylyov <s.shtylyov@omp.ru> Signed-off-by: Claudiu Beznea <claudiu.beznea.uj@bp.renesas.com> Signed-off-by: Paolo Abeni <pabeni@redhat.com>

2023-11-29ice: Fix VF Reset paths when interface in a failed over aggregateDave Ertman
There is an error when an interface has the following conditions: - PF is in an aggregate (bond) - PF has VFs created on it - bond is in a state where it is failed-over to the secondary interface - A VF reset is issued on one or more of those VFs The issue is generated by the originating PF trying to rebuild or reconfigure the VF resources. Since the bond is failed over to the secondary interface the queue contexts are in a modified state. To fix this issue, have the originating interface reclaim its resources prior to the tear-down and rebuild or reconfigure. Then after the process is complete, move the resources back to the currently active interface. There are multiple paths that can be used depending on what triggered the event, so create a helper function to move the queues and use paired calls to the helper (back to origin, process, then move back to active interface) under the same lag_mutex lock.

2023-11-28r8169: prevent potential deadlock in rtl8169_closeHeiner Kallweit
ndo_stop() is RTNL-protected by net core, and the worker function takes RTNL as well. Therefore we will deadlock when trying to execute a pending work synchronously. To fix this execute any pending work asynchronously. This will do no harm because netif_running() is false in ndo_stop(), and therefore the work function is effectively a no-op. However we have to ensure that no task is running or pending after rtl_remove_one(), therefore add a call to cancel_work_sync().

When a task needs to accept memory it will scan the accepting_list to see if any ranges already being processed by other tasks overlap with its range. Due to an off-by-one in the range comparisons, a task might falsely determine that an overlapping range is being accepted, leading to an unnecessary delay before it begins processing the range.

2023-11-28octeontx2-pf: Restore TC ingress police rules when interface is upSubbaraya Sundeep
TC ingress policer rules depends on interface receive queue contexts since the bandwidth profiles are attached to RQ contexts. When an interface is brought down all the queue contexts are freed. This in turn frees bandwidth profiles in hardware causing ingress police rules non-functional after the interface is brought up. Fix this by applying all the ingress police rules config to hardware in otx2_open.

2023-11-26dpaa2-eth: recycle the RX buffer only after all processing doneIoana Ciornei
The blamed commit added support for Rx copybreak. This meant that for certain frame sizes, a new skb was allocated and the initial data buffer was recycled. Instead of waiting to recycle the Rx buffer only after all processing was done on it (like accessing the parse results or timestamp information), the code path just went ahead and re-used the buffer right away. This sometimes lead to corrupted HW and SW annotation areas. Fix this by delaying the moment when the buffer is recycled.

2023-11-26dpaa2-eth: increase the needed headroom to account for alignmentIoana Ciornei
Increase the needed headroom to account for a 64 byte alignment restriction which, with this patch, we make mandatory on the Tx path. The case in which the amount of headroom needed is not available is already handled by the driver which instead sends a S/G frame with the first buffer only holding the SW and HW annotation areas. Without this patch, we can empirically see data corruption happening between Tx and Tx confirmation which sometimes leads to the SW annotation area being overwritten. Since this is an old IP where the hardware team cannot help to understand the underlying behavior, we make the Tx alignment mandatory for all frames to avoid the crash on Tx conf. Also, remove the comment that suggested that this is just an optimization. This patch also sets the needed_headroom net device field to the usual value that the driver would need on the Tx path: - 64 bytes for the software annotation area - 64 bytes to account for a 64 byte aligned buffer address Fixes: 6e2387e8f19e ("staging: fsl-dpaa2/eth: Add Freescale DPAA2 Ethernet driver") Closes: https://lore.kernel.org/netdev/aa784d0c-85eb-4e5d-968b-c8f74fa86be6@gin.de/ Signed-off-by: Ioana Ciornei <ioana.ciornei@nxp.com> Signed-off-by: David S.
