| * | i40e: avoid NULL pointer dereference and recursive errors on early PCI errorGuilherme G Piccoli2016-10-041-0/+6
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Although rare, it's possible to hit PCI error early on device probe, meaning possibly some structs are not entirely initialized, and some might even be completely uninitialized, leading to NULL pointer dereference. The i40e driver currently presents a "bad" behavior if device hits such early PCI error: firstly, the struct i40e_pf might not be attached to pci_dev yet, leading to a NULL pointer dereference on access to pf->state. Even checking if the struct is NULL and avoiding the access in that case isn't enough, since the driver cannot recover from PCI error that early; in our experiments we saw multiple failures on kernel log, like: [549.664] i40e 0007:01:00.1: Initial pf_reset failed: -15 [549.664] i40e: probe of 0007:01:00.1 failed with error -15 [...] [871.644] i40e 0007:01:00.1: The driver for the device stopped because the device firmware failed to init. Try updating your NVM image. [871.644] i40e: probe of 0007:01:00.1 failed with error -32 [...] [872.516] i40e 0007:01:00.0: ARQ: Unknown event 0x0000 ignored Between the first probe failure (error -15) and the second (error -32) another PCI error happened due to the first bad probe. Also, driver started to flood console with those ARQ event messages. This patch will prevent these issues by allowing error recovery mechanism to remove the failed device from the system instead of trying to recover from early PCI errors during device probe.

Stefan Assmann provides the changes in this series to resolve an issue where when we run out of MSIx vectors, iWARP gets disabled automatically. First adds a check for "no vectors left" during MSIx vector allocation for VMDq, which will prevent more vectors being allocated than available. Then fixed the MSIx vector redistribution when we reach the hardware limit for vectors so that additional features like VMDq, iWARP, etc do not get starved for vectors because the PF is hogging all the resources. Lastly, fix the issue for flow director by moving the check for the reaching the vector limit earlier in the code so that a decision can be made on disabling flow director. ==================== Signed-off-by: David S.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Currently if the MSI-X vector limit is reached the sideband flow director gets disabled.

On systems with 128 or more threads this currently means all vectors are used by the PF leaving no room for additional features like VMDq, iWARP, etc... The code that should redistribute the vectors in this case is broken and never triggers. Fixed the code so that it actually triggers if the hardware limit is reached and adjust the number of queue pairs accordingly. Also the number of initially requested iWARP vectors was not properly saved when the vector limit was reached, and therefore always zero. Comparison with debug statement. Before: i40e 0000:2d:00.0: VMDq disabled, not enough MSI-X vectors i40e 0000:2d:00.0: IWARP disabled, not enough MSI-X vectors i40e 00.0 MSI-X vector distribution: PF 128, VMDq 0, FDSB 0, iWARP 0 After: i40e 0000:2d:00.0: MSI-X vector limit reached, attempting to redistribute vectors i40e 00.0 MSI-X vector distribution: PF 78, VMDq 8, FDSB 0, iWARP 42 Signed-off-by: Stefan Assmann <sassmann@kpanic.de> Tested-by: Andrew Bowers <andrewx.bowers@intel.com> Signed-off-by: Jeff Kirsher <jeffrey.t.kirsher@intel.com>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add support for reading addresses, interrupts, and _DSD properties from ACPI tables, just like with device tree. The HID for the EMAC device itself is QCOM8070. The internal PHY is represented by a child node with a HID of QCOM8071. The EMAC also has some complex clock initialization requirements that are not represented by this patch. This will be addressed in a future patch.

This was previously fixed by commit 5dbebbb44a6a ("net: bcmgenet: Software reset EPHY after power on") but the commit we are reverting was essentially making this previous commit void, here is why. Without commit 62469c76007e we would have the following scenario after an ifconfig down then up sequence: - bcmgenet_open() calls bcmgenet_power_up() to make sure the PHY is initialized *before* we get to initialize the UniMAC, this is critical to ensure the PHY is in a correct state, priv->phydev is valid, this code executes fine - second time from bcmgenet_mii_probe(), through the normal phy_init_hw() call (which arguably could be optimized out) Everything is fine in that case. With commit 62469c76007e, we would have the following scenario to happen after an ifconfig down then up sequence: - bcmgenet_close() calls phy_disonnect() which makes dev->phydev become NULL - when bcmgenet_open() executes again and calls bcmgenet_mii_reset() from bcmgenet_power_up() to initialize the internal PHY, the NULL check becomes true, so we do not reset the PHY, yet we keep going on and initialize the UniMAC, causing MAC activity to occur - we call bcmgenet_mii_reset() from bcmgenet_mii_probe(), but this is too late, the PHY is botched, and causes the above bogus pings/packets transmission/reception to occur Reported-by: Jaedon Shin <jaedon.shin@gmail.com> Signed-off-by: Florian Fainelli <f.fainelli@gmail.com> Signed-off-by: Philippe Reynes <tremyfr@gmail.com> Signed-off-by: David S.
