It follows symptoms of fw error such as fw syndrome by triggering fw core dump and storing it and any other fw trace into the dump buffer. The fw reporter diagnose command can be triggered any time by the user to check current fw status. 4.2) fw_fatal repoter: The fw_fatal reporter implements dump and recover callbacks. It follows fatal errors indications by CR-space dump and recover flow. The CR-space dump uses vsc interface which is valid even if the FW command interface is not functional, which is the case in most FW fatal errors. The CR-space dump is stored as a memory region snapshot to ease read by address. The recover function runs recover flow which reloads the driver and triggers fw reset if needed. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>

* | ipv4: Support multipath hashing on inner IP pkts for GRE tunnelStephen Suryaputra2019-06-151-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Multipath hash policy value of 0 isn't distributing since the outer IP dest and src aren't varied eventhough the inner ones are. Since the flow is on the inner ones in the case of tunneled traffic, hashing on them is desired. This is done mainly for IP over GRE, hence only tested for that. But anything else supported by flow dissection should work. v2: Use skb_flow_dissect_flow_keys() directly so that other tunneling can be supported through flow dissection (per Nikolay Aleksandrov). v3: Remove accidental inclusion of ports in the hash keys and clarify the documentation (Nikolay Alexandrov).

* | net/tls: add kernel-driven resync mechanism for TXJakub Kicinski2019-06-111-1/+34
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | TLS offload drivers keep track of TCP seq numbers to make sure the packets are fed into the HW in order. When packets get dropped on the way through the stack, the driver will get out of sync and have to use fallback encryption, but unless TCP seq number is resynced it will never match the packets correctly (or even worse - use incorrect record sequence number after TCP seq wraps). Existing drivers (mlx5) feed the entire record on every out-of-order event, allowing FW/HW to always be in sync. This patch adds an alternative, more akin to the RX resync. When driver sees a frame which is past its expected sequence number the stream must have gotten out of order (if the sequence number is smaller than expected its likely a retransmission which doesn't require resync). Driver will ask the stack to perform TX sync before it submits the next full record, and fall back to software crypto until stack has performed the sync.

* | net/tls: add kernel-driven TLS RX resyncJakub Kicinski2019-06-111-0/+19
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | TLS offload device may lose sync with the TCP stream if packets arrive out of order. Drivers can currently request a resync at a specific TCP sequence number. When a record is found starting at that sequence number kernel will inform the device of the corresponding record number. This requires the device to constantly scan the stream for a known pattern (constant bytes of the header) after sync is lost. This patch adds an alternative approach which is entirely under the control of the kernel. Kernel tracks records it had to fully decrypt, even though TLS socket is in TLS_HW mode. If multiple records did not have any decrypted parts - it's a pretty strong indication that the device is out of sync. We choose the min number of fully encrypted records to be 2, which should hopefully be more than will get retransmitted at a time. After kernel decides the device is out of sync it schedules a resync request. If the TCP socket is empty the resync gets performed immediately. If socket is not empty we leave the record parser to resync when next record comes. Before resync in message parser we peek at the TCP socket and don't attempt the sync if the socket already has some of the next record queued. On resync failure (encrypted data continues to flow in) we retry with exponential backoff, up to once every 128 records (with a 16k record thats at most once every 2M of data).

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The Keystone 2 66AK2HK/E/L 1G Ethernet Switch Subsystems contains The Common Platform Time Sync (CPTS) module which is in general compatible with CPTS module found on "legacy" TI AM3/4/5 SoCs. So, the basic support for Keystone 2 CPTS is available by default, but not documented. The Keystone 2 CPTS module supports also some additional features like time sync reference (RFTCLK) clock selection through CPTS_RFTCLK_SEL register (offset: x08) in CPTS module, which is modelled as multiplexer clock. This patch adds missed binding documentation for Keystone 2 66AK2HK/E/L CPTS module.

The current situation is fairly confusing, because people interacting with cgroups expect hierarchical behaviour in the vein of memory.stat, cgroup.events, and other files. For example, this causes confusion when debugging reclaim events under low, as currently these always read "0" at non-leaf memcg nodes, which frequently causes people to misdiagnose breach behaviour. The same confusion applies to other counters in this file when debugging issues. Aggregation is done at write time instead of at read-time since these counters aren't hot (unlike memory.stat which is per-page, so it does it at read time), and it makes sense to bundle this with the file notifications. After this patch, events are propagated up the hierarchy: [root@ktst ~]# cat /sys/fs/cgroup/system.slice/memory.events low 0 high 0 max 0 oom 0 oom_kill 0 [root@ktst ~]# systemd-run -p MemoryMax=1 true Running as unit: run-r251162a189fb4562b9dabfdc9b0422f5.service [root@ktst ~]# cat /sys/fs/cgroup/system.slice/memory.events low 0 high 0 max 7 oom 1 oom_kill 1 As this is a change in behaviour, this can be reverted to the old behaviour by mounting with the `memory_localevents' flag set. However, we use the new behaviour by default as there's a lack of evidence that there are any current users of memory.events that would find this change undesirable. akpm: this is a behaviour change, so Cc:stable. THis is so that forthcoming distros which use cgroup v2 are more likely to pick up the revised behaviour.

This has happened now (with a very small number of exceptions), so I guess it's time to try again. We currently have three ISDN stacks in the kernel: the original isdn4linux (with the hisax driver), the newer CAPI (with four drivers), and finally the mISDN stack (supporting roughly the same hardware as hisax). As far as I can tell, anyone using ISDN with mainline kernel drivers in the past few years uses mISDN, and this is typically used for voice-only PBX installations that don't require a public network. The older stacks support additional features for data networks, but those typically make no sense any more if there is no network to connect to. My proposal for this time is to kill off isdn4linux entirely, as it seems to have been unusable for quite a while. This code has been abandoned for many years and it does cause problems for treewide maintenance as it tends to do everything that we try to stop doing. Birger Harzenetter mentioned that is is still using i4l in order to make use of the 'divert' feature that is not part of mISDN, but has otherwise moved on to mISDN for normal operation, like apparently everyone else. CAPI in turn is not quite as obsolete, but two of the drivers (avm and hysdn) don't seem to be used at all, while another one (gigaset) will stop being maintained as Paul Bolle is no longer able to test it after the network gets shut down in September. All three are now moved into drivers/staging to let others speak up in case there are remaining users. This leaves Bluetooth CMTP as the only remaining user of CAPI, but Marcel Holtmann wishes to keep maintaining it. For the discussion on version 1, see [2] Unfortunately, Karsten Keil as the maintainer has not participated in the discussion.

However, from looking at the mailing list, it seems that the last time anyone asked about it was in 2014, when the upgrade from a linux-2.4 installation failed, and mISDN was suggested as a replacement. The largest public ISDN network (Deutsche Telekom) was supposed to be shut down 2018, which must have drastically reduced the number of legacy installations. When we last discussed removing i4l in 2016, Karsten Keil suggested revisiting this in 2018. I guess this is overdue.

Birger Harzenetter noted that he is still using i4l/hisax to take advantage of the 'divert' driver for call diversion, but otherwise uses mISDN on the same hardware. This is a rare edge case as far as I can tell, but we are still breaking an actively used work flow (see https://xkcd.com/1172/). We debated moving i4l/hisax to staging as an intermediate step, but as he is not likely to change the setup, and that would just delay breaking this use case. The alternatives here are to stay on stable kernels < 5.2, to create an external driver repository for isdn4linux, or to add divert functionality to mISDN.

As part of that, we also need a few fixes to the docs for places where the new Sphinx is more strict. It is a bit late in the cycle for this kind of change, but it does fix problems that people are experiencing now. There has been some talk of raising the minimum version of Sphinx we support. I don't want to do that abruptly, though, so these changes add some glue to continue to support versions back to 1.3.
