The cast type currently gets selected in .ndo_start_xmit, and is then piped through several layers until it's stored into the HW header. Push the selection down into qeth_l?_fill_header() to (1) reduce the number of xmit-wide parameters, and (2) merge the two route validation checks into just one. Signed-off-by:

Use napi_gro_receive() to pass up all types of packets that a L3 device may receive. 1) For proper L2 packets received by the IQD sniffer, this is the obvious thing to do. 2) For af_iucv (which doesn't provide a GRO assist), the GRO code will transparently fall back to netif_receive_skb(). So there's no need to special-case this traffic in our code. Signed-off-by:

Apply some cleanups to qeth_snmp_command() and its callback: 1. when accessing the user data, use the proper struct instead of hard-coded offsets. Also copy the request data straight into the allocated cmd, skipping the extra memdup_user() to a tmp buffer. 2. capping the request length is no longer needed, the same check gets applied at a base level in qeth_alloc_cmd(). 3. clean up some duplicated (and misindented) trace statements.

Now that all cmds are dynamically allocated, the code for static cmd buffers can go away entirely. Resulting in a nice reduction of code/data size & complexity, while removing the risk that qeth_clear_cmd_buffers() releases cmds that are still in-flight. Signed-off-by:

The base MPC cmds are the last remaining user of the static cmd buffers. Port them over to use dynamic allocation, and stop backing the write channel's cmd buffers with pages. Signed-off-by:

Julian Wiedmann authored
The VNICC code is somewhat quirky in that it defers the whole cmd setup to a common helper qeth_l2_vnicc_request(). Some of the cmd specifics are then passed in via parameter, while others are simply hard-coded. Split the whole machinery up into the usual format: one helper that allocates the cmd & fills in the common fields, while all the cmd originators take care of their sub-cmd type specific work. This makes it much easier to calculate the cmd's precise length, and reduces code complexity. Signed-off-by:

Julian Wiedmann authored
This patch converts the adapter, assist and bridgeport cmd paths to dynamic allocation. Most of the work is about re-organizing the cmd headers, calculating the correct cmd length, and filling in the right value in the sub-cmd's length field. Since we now also set the correct length for cmds that are not reflected by a fixed struct (ie SNMP), we can remove the work-around from qeth_snmp_command(). Signed-off-by:

Julian Wiedmann authored
For code that uses qeth_send_simple_setassparms_prot(), we currently can't differentiate whether the cmd should contain (1) no parameter, or (2) a 4-byte parameter with value 0. At the moment this doesn't cause any trouble. But when using dynamically allocated cmds, we need to know whether to allocate & transmit an additional 4 bytes of zeroes. So instead of the raw parameter value, pass a parameter pointer (or NULL) to qeth_send_simple_setassparms_prot(). Signed-off-by:

This patch reduces the usage of the write channel's static cmd buffers, by dynamically allocating all simple IPA cmds (eg. STARTLAN, SETVMAC). It also converts the OSN path. Doing so requires some changes to how we calculate the cmd length. Currently when building IPA cmds, we're quite generous in how much data we send down to the device (basically the size of the biggest cmd we know). This is no real concern at the moment, since the static cmd buffers are backed with zeroed pages. But for dynamic allocations, the exact length matters. So this patch also adds the needed length calculations to each cmd path. Commands that have multiple subtypes (eg. SETADP) of differing length will be converted with follow-up patches. Signed-off-by:

When parsing an ethtool_rx_flow_spec, users can specify an ethernet flow which could contain matches based on the ethernet header, such as the MAC address, the VLAN tag or the ethertype. ETHER_FLOW uses the src and dst ethernet addresses, along with the ethertype as keys. Matches based on the vlan tag are also possible, but they are specified using the special FLOW_EXT flag.

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: -
Palmer Dabbelt authored
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:

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:

We add override_pci_need_reset to prevent redundant and unwanted PF resets if a RAS error occurs in commit 69b51bbb ("net: hns3: fix to stop multiple HNS reset due to the AER changes"). Now in HNS3 driver, we use hw_err_reset_req to record reset level that we need to recover from a RAS error. This variable cans solve above issue as override_pci_need_reset, so this patch removes override_pci_need_reset. Signed-off-by:
