2020-09-08rxrpc: Rewrite the client connection managerDavid Howells1-29/+4
Rewrite the rxrpc client connection manager so that it can support multiple connections for a given security key to a peer. The following changes are made: (1) For each open socket, the code currently maintains an rbtree with the connections placed into it, keyed by communications parameters. This is tricky to maintain as connections can be culled from the tree or replaced within it. Connections can require replacement for a number of reasons, e.g. their IDs span too great a range for the IDR data type to represent efficiently, the call ID numbers on that conn would overflow or the conn got aborted. This is changed so that there's now a connection bundle object placed in the tree, keyed on the same parameters. The bundle, however, does not need to be replaced. (2) An rxrpc_bundle object can now manage the available channels for a set of parallel connections. The lock that manages this is moved there from the rxrpc_connection struct (channel_lock). (3) There'a a dummy bundle for all incoming connections to share so that they have a channel_lock too. It might be better to give each incoming connection its own bundle. This bundle is not needed to manage which channels incoming calls are made on because that's the solely at whim of the client. (4) The restrictions on how many client connections are around are removed. Instead, a previous patch limits the number of client calls that can be allocated. Ordinarily, client connections are reaped after 2 minutes on the idle queue, but when more than a certain number of connections are in existence, the reaper starts reaping them after 2s of idleness instead to get the numbers back down. It could also be made such that new call allocations are forced to wait until the number of outstanding connections subsides. Signed-off-by: David Howells <dhowells@redhat.com>

2020-09-08fbdev: via-core: use generic power managementVaibhav Gupta1-2/+0
Drivers should do only device-specific jobs. But in general, drivers using legacy PCI PM framework for .suspend()/.resume() have to manage many PCI PM-related tasks themselves which can be done by PCI Core itself. This brings extra load on the driver and it directly calls PCI helper functions to handle them. Switch to the new generic framework by updating function signatures and define a "struct dev_pm_ops" variable to bind PM callbacks. The via_suspend() is designed to function only in the case of Suspend. Thus, the code checked for "if (state.event != PM_EVENT_SUSPEND)". This is because, in the legacy framework, this callback was invoked even in the event of Freeze and Hibernate. Hence, added the load of unnecessary function-calls. The goal can be achieved by binding the callback with only "via_pm_ops.suspend" in the new framework. This also avoids the step of checking "if (state.event != PM_EVENT_SUSPEND)" every time the callback is invoked.

2020-09-08netfilter: nf_tables: coalesce multiple notifications into one skbuffPablo Neira Ayuso1-0/+1
On x86_64, each notification results in one skbuff allocation which consumes at least 768 bytes due to the skbuff overhead. This patch coalesces several notifications into one single skbuff, so each notification consumes at least ~211 bytes, that ~3.5 times less memory consumption. As a result, this is reducing the chances to exhaust the netlink socket receive buffer. Rule of thumb is that each notification batch only contains netlink messages whose report flag is the same, nfnetlink_send() requires this to do appropriate delivery to userspace, either via unicast (echo mode) or multicast (monitor mode). The skbuff control buffer is used to annotate the report flag for later handling at the new coalescing routine. The batch skbuff notification size is NLMSG_GOODSIZE, using a larger skbuff would allow for more socket receiver buffer savings (to amortize the cost of the skbuff even more), however, going over that size might break userspace applications, so let's be conservative and stick to NLMSG_GOODSIZE.

2020-09-07net: tighten the definition of interface statisticsJakub Kicinski1-17/+187
This patch is born out of an investigation into which IEEE statistics correspond to which struct rtnl_link_stats64 members. Turns out that there seems to be reasonable consensus on the matter, among many drivers. To save others the time (and it took more time than I'm comfortable admitting) I'm adding comments referring to IEEE attributes to struct rtnl_link_stats64. Up until now we had two forms of documentation for stats - in Documentation/ABI/testing/sysfs-class-net-statistics and the comments on struct rtnl_link_stats64 itself. While the former is very cautious in defining the expected behavior, the latter feel quite dated and may not be easy to understand for modern day driver author (e.g. rx_over_errors). At the same time modern systems are far more complex and once obvious definitions lost their clarity. For example - does rx_packet count at the MAC layer (aFramesReceivedOK)? packets processed correctly by hardware? received by the driver? or maybe received by the stack? I tried to clarify the expectations, further clarifications from others are very welcome. The part hardest to untangle is rx_over_errors vs rx_fifo_errors vs rx_missed_errors. After much deliberation I concluded that for modern HW only two of the counters will make sense. The distinction between internal FIFO overflow and packets dropped due to back-pressure from the host is likely too implementation (driver and device) specific to expose in the standard stats. Now - which two of those counters we select to use is anyone's pick: sysfs documentation suggests rx_over_errors counts packets which did not fit into buffers due to MTU being too small, which I reused. There don't seem to be many modern drivers using it (well, CAN drivers seem to love this statistic). Of the remaining two I picked rx_missed_errors to report device drops. bnxt reports it and it's folded into "drop"s in procfs (while rx_fifo_errors is an error, and modern devices usually receive the frame OK, they just can't admit it into the pipeline). Of the drivers I looked at only AMD Lance-like and NS8390-like use all three of these counters. rx_missed_errors counts missed frames, rx_over_errors counts overflow events, and rx_fifo_errors counts frames which were truncated because they didn't fit into buffers. This suggests that rx_fifo_errors may be the correct stat for truncated packets, but I'd think a FIFO stat counting truncated packets would be very confusing to a modern reader. v2: - add driver developer notes about ethtool stat count and reset - replace Ethernet with IEEE 802.3 to better indicate source of attrs - mention byte counters don't count FCS - clarify RX counter is from device to host - drop "sightly" from sysfs paragraph - add examples of ethtool stats - s/incoming/received/ s/incoming/transmitted/ Signed-off-by: Jakub Kicinski <kuba@kernel.org>

2020-09-07ASoC: SOF: use the sof_ipc_comp reserved bytes for extended dataKeyon Jie1-2/+2
Use the 32bit reserved member of the struct sof_ipc_comp as the extended data length, this will help to minimize the ABI change for adding new extended data to the struct sof_ipc_comp, usually only minor ABI version bump needed for every update with this new solution.

PCI host bridges often have different ways to access the root and child bus config spaces. The host bridge drivers have invented their own abstractions to handle this. Let's support having different root and child bus pci_ops so these per driver abstractions can be removed.

2020-09-07mmc: core: add a 'doing_init_tune' flag and a 'mmc_doing_tune' helperWolfram Sang1-0/+6
Our driver needs to know when tuning is in progress. 'doing_retune' only covers re-tuning, not the initial tuning. Add another flag to detect the initial tuning state and add a helper which tells us if any kind of tuning is going on. Only implemented for MMC currently because that's where we need it. SD can be added later if it becomes necessary.
