2024-04-08net: usb: lan78xx: Fixup EEEAndrew Lunn1-20/+22
The enabling/disabling of EEE in the MAC should happen as a result of auto negotiation. So move the enable/disable into lan783xx_phy_link_status_change() which gets called by phylib when there is a change in link status. lan78xx_set_eee() now just programs the hardware with the LPI timer value, and passed everything else to phylib, so it can correctly setup the PHY. lan743x_get_eee() relies on phylib doing most of the work, the MAC driver just adds the LPI timer value. Call phy_support_eee() to indicate the MAC does actually support EEE. Signed-off-by: Andrew Lunn <[email protected]> Reviewed-by: Oleksij Rempel <[email protected]> Signed-off-by: David S.

2024-04-08net: usb: ax88179_178a: non necessary second random mac addressJose Ignacio Tornos Martinez1-1/+0
If the mac address can not be read from the device registers or the devicetree, a random address is generated, but this was already done from usbnet_probe, so it is not necessary to call eth_hw_addr_random from here again to generate another random address. Indeed, when reset was also executed from bind, generate another random mac address invalidated the check from usbnet_probe to configure if the assigned mac address for the interface was random or not, because it is comparing with the initial generated random address. Now, with only a reset from open operation, it is just a harmless simplification. Signed-off-by: Jose Ignacio Tornos Martinez <[email protected]> Signed-off-by: David S. Miller <[email protected]>
2024-04-04net: usb: ax88179_178a: avoid the interface always configured as random addressJose Ignacio Tornos Martinez1-0/+2
After the commit d2689b6a86b9 ("net: usb: ax88179_178a: avoid two consecutive device resets"), reset is not executed from bind operation and mac address is not read from the device registers or the devicetree at that moment. Since the check to configure if the assigned mac address is random or not for the interface, happens after the bind operation from usbnet_probe, the interface keeps configured as random address, although the address is correctly read and set during open operation (the only reset now). In order to keep only one reset for the device and to avoid the interface always configured as random address, after reset, configure correctly the suitable field from the driver, if the mac address is read successfully from the device registers or the devicetree. Take into account if a locally administered address (random) was previously stored. cc: [email protected] # 6.6+ Fixes: d2689b6a86b9 ("net: usb: ax88179_178a: avoid two consecutive device resets") Reported-by: Dave Stevenson <[email protected]> Signed-off-by: Jose Ignacio Tornos Martinez <[email protected]> Reviewed-by: Simon Horman <[email protected]> Link: https://lore.kernel.org/r/[email protected] Signed-off-by: Jakub Kicinski <[email protected]>

2024-03-01net: lan78xx: fix runtime PM count underflow on link stopOleksij Rempel1-1/+2
Current driver has some asymmetry in the runtime PM calls. On lan78xx_open() it will call usb_autopm_get() and unconditionally usb_autopm_put(). And on lan78xx_stop() it will call only usb_autopm_put(). So far, it was working only because this driver do not activate autosuspend by default, so it was visible only by warning "Runtime PM usage count underflow!". Since, with current driver, we can't use runtime PM with active link, execute lan78xx_open()->usb_autopm_put() only in error case. Otherwise, keep ref counting high as long as interface is open.

2024-02-27net: usb: dm9601: fix wrong return value in dm9601_mdio_readJavier Carrasco1-1/+1
The MII code does not check the return value of mdio_read (among others), and therefore no error code should be sent. A previous fix to the use of an uninitialized variable propagates negative error codes, that might lead to wrong operations by the MII library. An example of such issues is the use of mii_nway_restart by the dm9601 driver. The mii_nway_restart function does not check the value returned by mdio_read, which in this case might be a negative number which could contain the exact bit the function checks (BMCR_ANENABLE = 0x1000). Return zero in case of error, as it is common practice in users of mdio_read to avoid wrong uses of the return value.

Same as LAN7800, LAN7850 can be used without EEPROM. If EEPROM is not present or not flashed, LAN7850 will fail to sync the speed detected by the PHY with the MAC. In case link speed is 100Mbit, it will accidentally work, otherwise no data can be transferred. Better way would be to implement link_up callback, or set auto speed configuration unconditionally. But this changes would be more intrusive. So, for now, set it only if no EEPROM is found. Fixes: e69647a19c87 ("lan78xx: Set ASD in MAC_CR when EEE is enabled.")

2023-12-04r8152: Choose our USB config with choose_configuration() rather than probe()Douglas Anderson1-11/+5
If you deauthorize the r8152 device (by writing 0 to the "authorized" field in sysfs) and then reauthorize it (by writing a 1) then it no longer works. This is because when you do the above we lose the special configuration that we set in rtl8152_cfgselector_probe(). Deauthorizing causes the config to be set to -1 and then reauthorizing runs the default logic for choosing the best config. I made an attempt to fix it so that the config is kept across deauthorizing / reauthorizing [1] but it was a bit ugly. Let's instead use the new USB core feature to override choose_configuration(). This patch relies upon the patches ("usb: core: Don't force USB generic_subclass drivers to define probe()") and ("usb: core: Allow subclassed USB drivers to override usb_choose_configuration()") [1] https://lore.kernel.org/r/20231130154337.1.Ie00e07f07f87149c9ce0b27ae4e26991d307e14b@changeid Fixes: ec51fbd1b8a2 ("r8152: add USB device driver for config selection") Suggested-by: Alan Stern <[email protected]> Signed-off-by: Douglas Anderson <[email protected]> Reviewed-by: Grant Grundler <[email protected]> Link: https://lore.kernel.org/r/20231201102946.v2.3.Ie00e07f07f87149c9ce0b27ae4e26991d307e14b@changeid Signed-off-by: Greg Kroah-Hartman <[email protected]>

2023-12-04r8152: Hold the rtnl_lock for all of resetDouglas Anderson1-6/+7
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.

Using generic ASIX Electronics Corp. AX88179 Gigabit Ethernet device, the following test cycle has been implemented: - power on - check logs - shutdown - after detecting the system shutdown, disconnect power - after approximately 60 seconds of sleep, power is restored Running some cycles, sometimes error logs like this appear: kernel: ax88179_178a 2-9:1.0 (unnamed net_device) (uninitialized): Failed to write reg index 0x0001: -19 kernel: ax88179_178a 2-9:1.0 (unnamed net_device) (uninitialized): Failed to read reg index 0x0001: -19 ... These failed operation are happening during ax88179_reset execution, so the initialization could not be correct. In order to avoid this, we need to increase the delay after reset and clock initial operations. By using these larger values, many cycles have been run and no failed operations appear. It would be better to check some status register to verify when the operation has finished, but I do not have found any available information (neither in the public datasheets nor in the manufacturer's driver). The only available information for the necessary delays is the maufacturer's driver (original values) but the proposed values are not enough for the tested devices.

If a device sends a packet that is inbetween 0 and sizeof(u64) the value passed to skb_trim() as length will wrap around ending up as some very large value. The driver will then proceed to parse the header located at that position, which will either oops or process some random value. The fix is to check against sizeof(u64) rather than 0, which the driver currently does. The issue exists since the introduction of the driver.
