| 2020-01-08 | sfc: further preparation for code split | Alex Maftei (amaftei) | |
| Added more arguments for a couple of functions. Also moved a function to the common header. Signed-off-by: Alexandru-Mihai Maftei <amaftei@solarflare.com> Signed-off-by: David S. Miller <davem@davemloft.net> | |||
| 2020-01-08 | sfc: add new headers in preparation for code split | Alex Maftei (amaftei) | |
| New headers contain prototypes of functions that will be common between ef10 and upcoming driver. Removed static modifier from the affected functions. Some function prototypes were removed from existing headers. Signed-off-by: Alexandru-Mihai Maftei <amaftei@solarflare.com> Signed-off-by: David S. Miller <davem@davemloft.net> | |||

| 2019-12-30 | sfc: avoid duplicate error handling code in 'efx_ef10_sriov_set_vf_mac()' | Christophe JAILLET | |
| 'eth_zero_addr()' is already called in the error handling path. This is harmless, but there is no point in calling it twice, so remove one. Signed-off-by: Christophe JAILLET <christophe.jaillet@wanadoo.fr> Signed-off-by: David S. Miller <davem@davemloft.net> | |||

| 2019-12-20 | sfc: Include XDP packet headroom in buffer step size. | Charles McLachlan | |
| Correct a mismatch between rx_page_buf_step and the actual step size used when filling buffer pages. This patch fixes the page overrun that occured when the MTU was set to anything bigger than 1692.

| 2019-12-20 | sfc: fix channel allocation with brute force | Edward Cree | |
| It was possible for channel allocation logic to get confused between what it had and what it wanted, and end up trying to use the same channel for both PTP and regular TX. This led to a kernel panic: BUG: unable to handle page fault for address: 0000000000047635 #PF: supervisor write access in kernel mode #PF: error_code(0x0002) - not-present page PGD 0 P4D 0 Oops: 0002 [#1] SMP PTI CPU: 0 PID: 0 Comm: swapper/0 Tainted: G W 5.4.0-rc3-ehc14+ #900 Hardware name: Dell Inc.

| In high connection count usage, the NIC's filter table may be filled with sufficiently many ARFS filters that further insertions fail. As this does not represent a correctness issue, do not log the resulting MCDI errors. Add a debug-level message under the (by default disabled) rx_status category instead; and take the opportunity to do a little extra expiry work. Since there are now multiple workitems able to call __efx_filter_rfs_expire on a given channel, it is possible for them to race and thus pass quotas which, combined, exceed rfs_filter_count. Thus, don't WARN_ON if we loop all the way around the table with quota left over.

| The old rfs_filters_added method for determining the quota could potentially allow the NIC to become filled with old filters, which never get tested for expiry. Instead, explicitly make expiry check work depend on the number of filters installed, and don't count checking slots without filters in as doing work. This guarantees that each filter will be checked for expiry at least once every thirty seconds (assuming the channel to which it belongs is NAPI polling actively) regardless of fill level.

| 2019-04-08 | drivers: Remove explicit invocations of mmiowb() | Will Deacon | |
| mmiowb() is now implied by spin_unlock() on architectures that require it, so there is no reason to call it from driver code. This patch was generated using coccinelle: @mmiowb@ @@ - mmiowb(); and invoked as: $ for d in drivers include/linux/qed sound; do \ spatch --include-headers --sp-file mmiowb.cocci --dir $d --in-place; done NOTE: mmiowb() has only ever guaranteed ordering in conjunction with spin_unlock(). However, pairing each mmiowb() removal in this patch with the corresponding call to spin_unlock() is not at all trivial, so there is a small chance that this change may regress any drivers incorrectly relying on mmiowb() to order MMIO writes between CPUs using lock-free synchronisation. If you've ended up bisecting to this commit, you can reintroduce the mmiowb() calls using wmb() instead, which should restore the old behaviour on all architectures other than some esoteric ia64 systems.

| The netfilter conflicts were rather simple overlapping changes. However, the cls_tcindex.c stuff was a bit more complex. On the 'net' side, Cong is fixing several races and memory leaks. Whilst on the 'net-next' side we have Vlad adding the rtnl-ness support. What I've decided to do, in order to resolve this, is revert the conversion over to using a workqueue that Cong did, bringing us back to pure RCU. I did it this way because I believe that either Cong's races don't apply with have Vlad did things, or Cong will have to implement the race fix slightly differently. Signed-off-by: David S.

| 2019-02-14 | sfc: ensure recovery after allocation failures | Robert Stonehouse | |
| After failing to allocate a receive buffer the driver may fail to ever request additional allocations. EF10 NICs require new receive buffers to be pushed in batches of eight or more. The test for whether a slow fill should be scheduled failed to take account of this. There is little downside to *always* requesting a slow fill if we failed to allocate a buffer, so the condition has been removed completely. The timer that triggers the request for a refill has also been shortened.

| 2019-01-23 | sfc: suppress duplicate nvmem partition types in efx_ef10_mtd_probe | Edward Cree | |
| Use a bitmap to keep track of which partition types we've already seen; for duplicates, return -EEXIST from efx_ef10_mtd_probe_partition() and thus skip adding that partition. Duplicate partitions occur because of the A/B backup scheme used by newer sfc NICs. Prior to this patch they cause sysfs_warn_dup errors because they have the same name, causing us not to expose any MTDs at all.

| Pull networking updates from David Miller: 1) New ipset extensions for matching on destination MAC addresses, from Stefano Brivio. 2) Add ipv4 ttl and tos, plus ipv6 flow label and hop limit offloads to nfp driver. From Stefano Brivio. 3) Implement GRO for plain UDP sockets, from Paolo Abeni. 4) Lots of work from Michał Mirosław to eliminate the VLAN_TAG_PRESENT bit so that we could support the entire vlan_tci value. 5) Rework the IPSEC policy lookups to better optimize more usecases, from Florian Westphal. 6) Infrastructure changes eliminating direct manipulation of SKB lists wherever possible, and to always use the appropriate SKB list helpers. This work is still ongoing... 7) Lots of PHY driver and state machine improvements and simplifications, from Heiner Kallweit. 8) Various TSO deferral refinements, from Eric Dumazet. 9) Add ntuple filter support to aquantia driver, from Dmitry Bogdanov. 10) Batch dropping of XDP packets in tuntap, from Jason Wang. 11) Lots of cleanups and improvements to the r8169 driver from Heiner Kallweit, including support for ->xmit_more. This driver has been getting some much needed love since he started working on it. 12) Lots of new forwarding selftests from Petr Machata. 13) Enable VXLAN learning in mlxsw driver, from Ido Schimmel. 14) Packed ring support for virtio, from Tiwei Bie. 15) Add new Aquantia AQtion USB driver, from Dmitry Bezrukov. 16) Add XDP support to dpaa2-eth driver, from Ioana Ciocoi Radulescu. 17) Implement coalescing on TCP backlog queue, from Eric Dumazet. 18) Implement carrier change in tun driver, from Nicolas Dichtel. 19) Support msg_zerocopy in UDP, from Willem de Bruijn. 20) Significantly improve garbage collection of neighbor objects when the table has many PERMANENT entries, from David Ahern. 21) Remove egdev usage from nfp and mlx5, and remove the facility completely from the tree as it no longer has any users. From Oz Shlomo and others. 22) Add a NETDEV_PRE_CHANGEADDR so that drivers can veto the change and therefore abort the operation before the commit phase (which is the NETDEV_CHANGEADDR event). From Petr Machata. 23) Add indirect call wrappers to avoid retpoline overhead, and use them in the GRO code paths. From Paolo Abeni. 24) Add support for netlink FDB get operations, from Roopa Prabhu. 25) Support bloom filter in mlxsw driver, from Nir Dotan. 26) Add SKB extension infrastructure. This consolidates the handling of the auxiliary SKB data used by IPSEC and bridge netfilter, and is designed to support the needs to MPTCP which could be integrated in the future. 27) Lots of XDP TX optimizations in mlx5 from Tariq Toukan. * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net-next: (1845 commits) net: dccp: fix kernel crash on module load drivers/net: appletalk/cops: remove redundant if statement and mask bnx2x: Fix NULL pointer dereference in bnx2x_del_all_vlans() on some hw net/net_namespace: Check the return value of register_pernet_subsys() net/netlink_compat: Fix a missing check of nla_parse_nested ieee802154: lowpan_header_create check must check daddr net/mlx4_core: drop useless LIST_HEAD mlxsw: spectrum: drop useless LIST_HEAD net/mlx5e: drop useless LIST_HEAD iptunnel: Set tun_flags in the iptunnel_metadata_reply from src net/mlx5e: fix semicolon.cocci warnings staging: octeon: fix build failure with XFRM enabled net: Revert recent Spectre-v1 patches. can: af_can: Fix Spectre v1 vulnerability packet: validate address length if non-zero nfc: af_nfc: Fix Spectre v1 vulnerability phonet: af_phonet: Fix Spectre v1 vulnerability net: core: Fix Spectre v1 vulnerability net: minor cleanup in skb_ext_add() net: drop the unused helper skb_ext_get() ... | |||
| 2018-12-06 | net: core: dev: Add extack argument to dev_open() | Petr Machata | |
| In order to pass extack together with NETDEV_PRE_UP notifications, it's necessary to route the extack to __dev_open() from diverse (possibly indirect) callers. One prominent API through which the notification is invoked is dev_open(). Therefore extend dev_open() with and extra extack argument and update all users. Most of the calls end up just encoding NULL, but bond and team drivers have the extack readily available.
