Joe Damato says: ==================== mlx4: Add support for netdev-genl API There are no functional changes from v5, which I mistakenly sent right after net-next was closed (oops). This revision, however, includes Tariq's Reviewed-by tags of the v5 in each commit message. See the changelog below. This series adds support to mlx4 for the netdev-genl API which makes it much easier for users and user programs to map NAPI IDs back to ifindexes, queues, and IRQs. This is extremely useful for a number of use cases, including epoll-based busy poll. In addition, this series includes a patch to generate per-queue statistics using the netlink API, as well. To facilitate the stats, patch 1/3 adds a field "alloc_fail" to the ring structure. This is incremented by the driver in an appropriate place and used in patch 3/3 as alloc_fail. Please note: I do not have access to mlx4 hardware, but I've been working closely with Martin Karsten from University of Waterloo (CC'd) who has very graciously tested my patches on their mlx4 hardware (hence his Tested-by attribution in each commit). His latest research work is particularly interesting [1] and this series helps to support that (and future) work. Martin re-test v4 using Jakub's suggested tool [2] and the stats.pkt_byte_sum and stats.qstat_by_ifindex tests passed. He also adjusted the queue count and re-ran test to confirm it still passed even if the queue count was modified.

MD Danish Anwar says: ==================== Introduce switch mode support for ICSSG driver This series adds support for switch-mode for ICSSG driver. This series also introduces helper APIs to configure firmware maintained FDB (Forwarding Database) and VLAN tables. These APIs are later used by ICSSG driver in switch mode. Now the driver will boot by default in dual EMAC mode. When first ICSSG interface is added to bridge driver will still be in EMAC mode. As soon as second ICSSG interface is added to same bridge, switch-mode will be enabled and switch firmwares will be loaded to PRU cores. The driver will remain in dual EMAC mode if ICSSG interfaces are added to two different bridges or if two different interfaces (One ICSSG, one other) is added to the same bridge. We'll only enable is_switch_mode flag when two ICSSG interfaces are added to same bridge. We start in dual MAC mode. Let's say lan0 and lan1 are ICSSG interfaces ip link add name br0 type bridge ip link set lan0 master br0 At this point, we get a CHANGEUPPER event. Only one port is a member of the bridge, so we will still be in dual MAC mode. ip link set lan1 master br0 We get a second CHANGEUPPER event, the second interface lan1 is also ICSSG interface so we will set the is_switch_mode flag and when interfaces are brought up again, ICSSG switch firmwares will be loaded to PRU Cores. There are some other cases to consider as well. ip link add name br0 type bridge ip link add name br1 type bridge ip link set lan0 master br0 ip link set ppp0 master br0 Here we are adding lan0 (ICSSG) and ppp0 (non ICSSG) to same bridge, as they both are not ICSSG, we will still be running in dual EMAC mode. ip link set lan1 master br1 ip link set vpn0 master br1 Here we are adding lan1 (ICSSG) and vpn0 (non ICSSG) to same bridge, as they both are not ICSSG, we will still be running in dual EMAC mode. This is v6 of the series. Changes from v5 to v6: *) Removed __packed from structures in icssg_config.h file. *) Added RB tags of Andrew Lunn <andrew@lunn.ch> to patch 2/3 and patch 3/3 of this series. Changes from v4 to v5: *) Rebased on 6.10-rc1. *) Dropped the RFC tag. Changes from v3 to v4: *) Added RFC tag as net-next is closed now. *) Modified the driver to remove the need of bringing interfaces up / down for enabling / disabling switch mode. Now switch mode can be enabled without bringig interfaces up / down as requested by Andrew Lunn <andrew@lunn.ch> *) Modified commit message of patch 3/3. Changes from v2 to v3: *) Dropped RFC tag. *) Used ether_addr_copy() instead of manually copying mac address using for loop in patch 1/3 as suggested by Andrew Lunn <andrew@lunn.ch> *) Added helper API icssg_fdb_setup() in patch 1/3 to reduce code duplication as suggested by Andrew Lunn <andrew@lunn.ch> *) In prueth_switchdev_stp_state_set() removed BR_STATE_LEARNING as learning without forwarding is not supported by ICSSG firmware. *) Used ether_addr_equal() wherever possible in patch 2/3 as suggested by Andrew Lunn <andrew@lunn.ch> *) Fixed typo "nit: s/prueth_switchdevice_nb/prueth_switchdev_nb/" in patch 2/3 as suggested by Simon Horman <horms@kernel.org> *) Squashed "#include "icssg_mii_rt.h" to patch 2/3 from patch 3/3 as suggested by Simon Horman <horms@kernel.org> *) Rebased on latest net-next/main.

Add support for ICSSG switch firmware using existing Dual EMAC driver with switchdev. Limitations: VLAN offloading is limited to 0-256 IDs. MDB/FDB static entries are limited to 511 entries and different FDBs can hash to same bucket and thus may not completely offloaded Example assuming ETH1 and ETH2 as ICSSG2 interfaces: Switch to ICSSG Switch mode: ip link add name br0 type bridge ip link set dev eth1 master br0 ip link set dev eth2 master br0 ip link set dev br0 up bridge vlan add dev br0 vid 1 pvid untagged self Going back to Dual EMAC mode: ip link set dev br0 down ip link set dev eth1 nomaster ip link set dev eth2 nomaster ip link del name br0 type bridge By default, Dual EMAC firmware is loaded, and can be changed to switch mode by above steps Reviewed-by:

These functions have races when they: 1) Write sk->sk_err 2) call sk_error_report(sk) 3) call tcp_done(sk) As described in prior patches in this series: An smp_wmb() is missing. We should call tcp_done() before sk_error_report(sk) to have consistent tcp_poll() results on SMP hosts. Use tcp_done_with_error() where we centralized the correct sequence.

tcp_abort() has the same issue than the one fixed in the prior patch in tcp_write_err(). In order to get consistent results from tcp_poll(), we must call sk_error_report() after tcp_done().

I noticed flakes in a packetdrill test, expecting an epoll_wait() to return EPOLLERR | EPOLLHUP on a failed connect() attempt, after multiple SYN retransmits. It sometimes return EPOLLERR only. The issue is that tcp_write_err(): 1) writes an error in sk->sk_err, 2) calls sk_error_report(), 3) then calls tcp_done(). tcp_done() is writing SHUTDOWN_MASK into sk->sk_shutdown, among other things. Problem is that the awaken user thread (from 2) sk_error_report()) might call tcp_poll() before tcp_done() has written sk->sk_shutdown. tcp_poll() only sees a non zero sk->sk_err and returns EPOLLERR. This patch fixes the issue by making sure to call sk_error_report() after tcp_done(). tcp_write_err() also lacks an smp_wmb(). We can reuse tcp_done_with_error() to factor out the details, as Neal suggested. Fixes: 1da177e4 ("Linux-2.6.12-rc2") Signed-off-by:

If a user provides an invalid netconsole configuration during boot time (e.g., specifying an invalid ethX interface), netconsole will be entirely disabled. Consequently, the user won't be able to create new entries in /sys/kernel/config/netconsole/ as that directory does not exist. Apart from misconfiguration, another issue arises when ethX is loaded as a module and the netconsole= line in the command line points to ethX, resulting in an obvious failure. This renders netconsole unusable, as /sys/kernel/config/netconsole/ will never appear. This is more annoying since users reconfigure (or just toggle) the configuratin later (see commit 5fbd6cdb ("netconsole: Attach cmdline target to dynamic target")) Create /sys/kernel/config/netconsole/ even if the command line arguments are invalid, so, users can create dynamic entries in netconsole.

An earlier commit deleted the TSO support in the Cortina Gemini driver because the driver was confusing gso_size and MTU, probably because what the Linux kernel calls "gso_size" was called "MTU" in the datasheet. Restore the functionality properly reading the gso_size from the skbuff. Tested with iperf3, running a server on a different machine and client on the device with the cortina gemini ethernet: Connecting to host 192.168.1.2, port 5201 60008000.ethernet-port eth0: segment offloading mss = 05ea len=1c8a 60008000.ethernet-port eth0: segment offloading mss = 05ea len=1c8a 60008000.ethernet-port eth0: segment offloading mss = 05ea len=27da 60008000.ethernet-port eth0: segment offloading mss = 05ea len=0b92 60008000.ethernet-port eth0: segment offloading mss = 05ea len=2bda (...)

Performance with iperf3 before this patch: ~15.5 Mbit/s Performance with iperf3 after this patch: ~175 Mbit/s This was running a 60 second test (twice) the best measurement was 179 Mbit/s. For comparison if I run iperf3 with UDP I get around 1.05 Mbit/s both before and after this patch. While this is a gigabit ethernet interface, the CPU is a cheap D-Link DIR-685 router (based on the ARMv5 Faraday FA526 at ~50 MHz), and the software is not supposed to drive traffic, as the device has a DSA chip, so this kind of numbers can be expected.

To reduce the size of that final commit, switch utility functions which are not bound by "typedef proc_handler" to "const struct ctl_table". No functional change. Signed-off-by:
