Palmer Dabbelt says: ==================== net: macb: Fix compilation on systems without COMMON_CLK, v2 Our patch to add support for the FU540-C000 broke compilation on at least powerpc allyesconfig, which was found as part of the linux-next build regression tests. This must have somehow slipped through the cracks, as the patch has been reverted in linux-next for a while now. This patch applies on top of the offending commit, which is the only one I've even tried it on as I'm not sure how this subsystem makes it to Linus. This patch set fixes the issue by adding a dependency of COMMON_CLK to the MACB Kconfig entry, which avoids the build failure by disabling MACB on systems where it wouldn't compile. All known users of MACB have COMMON_CLK, so this shouldn't cause any issues. This is a significantly simpler approach than disabling just the FU540-C000 support. I've also included a second patch to indicate this is a driver for a Cadence device that was originally written by an engineer at Atmel. The only relation is that I stumbled across it when writing the first patch. Changes since v1 <20190624061603.1704-1-palmer@sifive.com>: * Disable MACB on systems without COMMON_CLK, instead of just disabling the FU540-C000 support on these systems. * Update the commit message to reflect the driver was written by Atmel. ==================== Signed-off-by:David S. Miller <davem@davemloft.net>

The help text makes it look like NET_VENDOR_CADENCE enables support for Atmel devices, when in reality it's a driver written by Atmel that supports Cadence devices. This may confuse users that have this device on a non-Atmel SoC. The fix is just s/Atmel/Cadence/, but I did go and re-wrap the Kconfig help text as that change caused it to go over 80 characters.

commit c218ad55 ("macb: Add support for SiFive FU540-C000") added a dependency on the common clock framework to the macb driver, but didn't express that dependency in Kconfig. As a result macb now fails to compile on systems without COMMON_CLK, which specifically causes a build failure on powerpc allyesconfig. This patch adds the dependency, which results in the macb driver no longer being selectable on systems without the common clock framework. All known systems that have this device already support the common clock framework, so this should not cause trouble for any uses. Supporting both the FU540-C000 and systems without COMMON_CLK is quite ugly. I've build tested this on powerpc allyesconfig and RISC-V defconfig (which selects MACB), but I have not even booted the resulting kernels.

The longstanding prohibition against using 0.0.0.0/8 dates back to two issues with the early internet. There was an interoperability problem with BSD 4.2 in 1984, fixed in BSD 4.3 in 1986. BSD 4.2 has long since been retired. Secondly, addresses of the form 0.x.y.z were initially defined only as a source address in an ICMP datagram, indicating "node number x.y.z on this IPv4 network", by nodes that know their address on their local network, but do not yet know their network prefix, in RFC0792 (page 19). This usage of 0.x.y.z was later repealed in RFC1122 (section 3.2.2.7), because the original ICMP-based mechanism for learning the network prefix was unworkable on many networks such as Ethernet (which have longer addresses that would not fit into the 24 "node number" bits). Modern networks use reverse ARP (RFC0903) or BOOTP (RFC0951) or DHCP (RFC2131) to find their full 32-bit address and CIDR netmask (and other parameters such as default gateways). 0.x.y.z has had 16,777,215 addresses in 0.0.0.0/8 space left unused and reserved for future use, since 1989. This patch allows for these 16m new IPv4 addresses to appear within a box or on the wire. Layer 2 switches don't care. 0.0.0.0/32 is still prohibited, of course. Signed-off-by:

Puranjay Mohan says: ==================== net: fddi: skfp: Use PCI generic definitions instead of private duplicates This patch series removes the private duplicates of PCI definitions in favour of generic definitions defined in pci_regs.h. This driver only uses some of the generic PCI definitons, which are included from pci_regs.h and thier private versions are removed from skfbi.h with all other private defines. The skfbi.h defines PCI_REV_ID and other private defines with different names, these are renamed to Generic PCI names to make them compatible with defines in pci_regs.h. All unused defines are removed from skfbi.h. Changes in v5: Removed unused PCI definitions which were left in v4 Changes in v4: Removed unused PCI definitions which were left in v3 Changes in v3: Renamed all local PCI definitions to Generic names. Corrected coding style mistakes. Changes in v2: Converted individual patches to a series. Made sure that individual patches build correctly ==================== Signed-off-by: -

If the PHY does not support EEE mode, then a crash is observed when the ethernet interface is enabled. The crash occurs, because if the PHY does not support EEE, then although the EEE timer is never configured, it is still marked as enabled and so the stmmac ethernet driver is still trying to update the timer by calling mod_timer(). This triggers a BUG() in the mod_timer() because we are trying to update a timer when there is no callback function set because timer_setup() was never called for this timer. The problem is caused because we return true from the function stmmac_eee_init(), marking the EEE timer as enabled, even when we have not configured the EEE timer. Fix this by ensuring that we return false if the PHY does not support EEE and hence, 'eee_active' is not set.

When stmmac_eee_init() is called to disable EEE support, then the timer for EEE support is stopped and we return from the function. Prior to stopping the timer, a mutex was acquired but in this case it is never released and so could cause a deadlock. Fix this by releasing the mutex prior to returning from stmmax_eee_init() when stopping the EEE timer. Fixes: 74371272 ("net: stmmac: Convert to phylink and remove phylib logic") Signed-off-by:

This patch optimizes hclge_handle_hw_ras_error() to make the code logic clearer. 1. If there was no NIC or Roce RAS when we read HCLGE_RAS_PF_OTHER_INT_STS_REG, we return directly. 2. Because NIC and Roce RAS may occurs at the same time, so we should check value of revision at first before we handle Roce RAS instead of only checking it in branch of no NIC RAS is detected. 3. Check HCLGE_STATE_RST_HANDLING each time before we want to return PCI_ERS_RESULT_NEED_RESET. 4. Remove checking of HCLGE_RAS_REG_NFE_MASK and HCLGE_RAS_REG_ROCEE_ERR_MASK because if hw_err_reset_req is not zero, it proves that we have set it in handling of NIC or Roce RAS. Signed-off-by:

In commit a4dc70d4 ("tipc: extend link reset criteria for stale packet retransmission") we made link retransmission failure events dependent on the link tolerance, and not only of the number of failed retransmission attempts, as we did earlier. This works well. However, keeping the original, additional criteria of 99 failed retransmissions is now redundant, and may in some cases lead to failure detection times in the order of minutes instead of the expected 1.5 sec link tolerance value. We now remove this criteria altogether. Acked-by:

This patch restores the original behaviour for tdc prior to the introduction of the plugin system, where the network namespace functionality was split from the main script. It introduces the concept of required plugins for testcases, and will automatically load any plugin that isn't already enabled when said plugin is required by even one testcase. Additionally, the -n option for the nsPlugin is deprecated so the default action is to make use of the namespaces. Instead, we introduce -N to not use them, but still create the veth pair. buildebpfPlugin's -B option is also deprecated. If a test cases requires the features of a specific plugin in order to pass, it should instead include a new key/value pair describing plugin interactions: "plugins": { "requires": "buildebpfPlugin" }, A test case can have more than one required plugin: a list can be inserted as the value for 'requires'.

The AIRO driver applies a ctr(aes) on a buffer of considerable size (2400 bytes), and instead of invoking the crypto API to handle this in its entirety, it open codes the counter manipulation and invokes the AES block cipher directly. Let's fix this, by switching to the sync skcipher API instead. Signed-off-by:

Make watchdog disabled by default and add module parameter to enable it. User will have to create file in /etc/modprobe.d/ with options rt2800lib watchdog=1 to enable the watchdog or load "rt2800lib watchdog=1" module manually before loading rt2800{soc,pci,usb} module.

If we restart hw we should keep existing IV (initialization vector) otherwise HW encryption will be broken after restart. Also fix some coding style issues on the way. Signed-off-by:

Add watchdog for rt2800 devices. For now it only detect hung and print error. [Note: I verified that printing messages from process context is fine on MT7620 (WT3020) platform that have problem when printk is called from interrupt context]. Signed-off-by:

For mmio we do not properlly trace dma done Q_INDEX_DMA_DONE index for TX queues. That would require implementing INT_SOURCE_CSR_*_DMA_DONE interrupts, what is rather not worth to do due to adding extra CPU load (small but still somewhat not necessary otherwise). We can just read TX DMA done indexes from registers directly. What will be used by watchdog. Signed-off-by:
