| Several network drivers for chips that support TSO6 share the same code for preparing the TCP header, so let's factor it out to a helper. A difference is that some drivers reset the payload_len whilst others don't do this. This value is overwritten by TSO anyway, therefore the new helper resets it in general.

| 2020-02-19 | nfc: pn544: Fix occasional HW initialization failure | Dmitry Osipenko | 1 | -0/+1 | |
| The PN544 driver checks the "enable" polarity during of driver's probe and it's doing that by turning ON and OFF NFC with different polarities until enabling succeeds. It takes some time for the hardware to power-down, and thus, to deassert the IRQ that is raised by turning ON the hardware. Since the delay after last power-down of the polarity-checking process is missed in the code, the interrupt may trigger immediately after installing the IRQ handler (right after the checking is done), which results in IRQ handler trying to touch the disabled HW and ends with marking NFC as 'DEAD' during of the driver's probe: pn544_hci_i2c 1-002a: NFC: nfc_en polarity : active high pn544_hci_i2c 1-002a: NFC: invalid len byte shdlc: llc_shdlc_recv_frame: NULL Frame -> link is dead This patch fixes the occasional NFC initialization failure on Nexus 7 device.

| non-initial netns It is currenty possible to switch the TCP congestion control algorithm in non-initial network namespaces: unshare -U --map-root --net --fork --pid --mount-proc echo "reno" > /proc/sys/net/ipv4/tcp_congestion_control works just fine. But currently non-initial network namespaces have no way of kowing which congestion algorithms are available or allowed other than through trial and error by writing the names of the algorithms into the aforementioned file. Since we already allow changing the congestion algorithm in non-initial network namespaces by exposing the tcp_congestion_control file there is no reason to not also expose the tcp_{allowed,available}_congestion_control files to non-initial network namespaces.

| Jakub Sitnicki says: ==================== This series has been split out from "Extend SOCKMAP to store listening sockets" [0]. I think it stands on its own, and makes the latter series smaller, which will make the review easier, hopefully. The essence is that we don't need to do a complicated dance in sk_psock_restore_proto, if we agree that the contract with tcp_update_ulp is to restore callbacks even when the socket doesn't use ULP. This is what tcp_update_ulp currently does, and we just make use of it. Series is accompanied by a test for a particularly tricky case of restoring callbacks when we have both sockmap and tls callbacks configured in sk->sk_prot.

| 2020-02-19 | selftests/bpf: Test unhashing kTLS socket after removing from map | Jakub Sitnicki | 1 | -0/+123 | |
| When a TCP socket gets inserted into a sockmap, its sk_prot callbacks get replaced with tcp_bpf callbacks built from regular tcp callbacks. If TLS gets enabled on the same socket, sk_prot callbacks get replaced once again, this time with kTLS callbacks built from tcp_bpf callbacks. Now, we allow removing a socket from a sockmap that has kTLS enabled. After removal, socket remains with kTLS configured. This is where things things get tricky. Since the socket has a set of sk_prot callbacks that are a mix of kTLS and tcp_bpf callbacks, we need to restore just the tcp_bpf callbacks to the original ones. At the moment, it comes down to the the unhash operation. We had a regression recently because tcp_bpf callbacks were not cleared in this particular scenario of removing a kTLS socket from a sockmap. It got fixed in commit 4da6a196f93b ("bpf: Sockmap/tls, during free we may call tcp_bpf_unhash() in loop"). Add a test that triggers the regression so that we don't reintroduce it in the future.

| There is no need to clear psock->sk_proto when restoring socket protocol callbacks in sk->sk_prot. The psock is about to get detached from the sock and eventually destroyed. At worst we will restore the protocol callbacks and the write callback twice. This makes reasoning about psock state easier. Once psock is initialized, we can count on psock->sk_proto always being set.

| 2020-02-19 | iommu/arm-smmu: Restore naming of driver parameter prefix | Will Deacon | 1 | -2/+2 | |
| Extending the Arm SMMU driver to allow for modular builds changed KBUILD_MODNAME to be "arm_smmu_mod" so that a single module could be built from the multiple existing object files without the need to rename any source files. This inadvertently changed the name of the driver parameters, which may lead to runtime issues if bootloaders are relying on the old names for correctness (e.g. "arm-smmu.disable_bypass=0"). Although MODULE_PARAM_PREFIX can be overridden to restore the old naming for builtin parameters, only the new name is matched by modprobe and so loading the driver as a module would cause parameters specified on the kernel command line to be ignored. Instead, rename "arm_smmu_mod" to "arm_smmu". Whilst it's a bit of a bodge, this allows us to create a single module without renaming any files and makes use of the fact that underscores and hyphens can be used interchangeably in parameter names.

| On driver load: - Initialize resource dump data structure and memory access tools (mkey & pd). - Read the resource dump's menu which contains the FW segment identifier. Each record is identified by the segment name (ASCII). During the driver's course of life, users (like reporters) may request dumps per segment. The user should create a command providing the segment identifier (SW enumeration) and command keys. In return, the user receives a command context. In order to receive the dump, the user should supply the command context and a memory (aligned to a PAGE) on which the dump content will be written. Since the dump may be larger than the given memory, the user may resubmit the command until received an indication of end-of-dump. It is the user's responsibility to destroy the command.

| 2020-02-19 | net/mlx5e: Reset RQ doorbell counter before moving RQ state from RST to RDY | Aya Levin | 4 | -9/+43 | |
| Initialize RQ doorbell counters to zero prior to moving an RQ from RST to RDY state. Per HW spec, when RQ is back to RDY state, the descriptor ID on the completion is reset. The doorbell record must comply.

| 2020-02-19 | net/mlx5: Fix sleep while atomic in mlx5_eswitch_get_vepa | Huy Nguyen | 1 | -11/+3 | |
| rtnl_bridge_getlink is protected by rcu lock, so mlx5_eswitch_get_vepa cannot take mutex lock. Two possible issues can happen: 1. User at the same time change vepa mode via RTM_SETLINK command. 2. User at the same time change the switchdev mode via devlink netlink interface. Case 1 cannot happen because rtnl executes one message in order. Case 2 can happen but we do not expect user to change the switchdev mode when changing vepa. Even if a user does it, so he will read a value which is no longer valid.

| Pablo Neira Ayuso says: ==================== Netfilter fixes for net This batch contains Netfilter fixes for net: 1) Restrict hashlimit size to 1048576, from Cong Wang. 2) Check for offload flags from nf_flow_table_offload_setup(), this fixes a crash in case the hardware offload is disabled. From Florian Westphal. 3) Three preparation patches to extend the conntrack clash resolution, from Florian. 4) Extend clash resolution to deal with DNS packets from the same flow racing to set up the NAT configuration. 5) Small documentation fix in pipapo, from Stefano Brivio. 6) Remove misleading unlikely() from pipapo_refill(), also from Stefano. 7) Reduce hashlimit mutex scope, from Cong Wang. This patch is actually triggering another problem, still under discussion, another patch to fix this will follow up. ==================== Signed-off-by: David S. Miller <davem@davemloft.net> | |||||
