rxrpc: Fix the rxrpc_connection attend queue handling

2025-02-04T14:30:28Z

The rxrpc_connection attend queue is never used because conn::attend_link is never initialised and so is always NULL'd out and thus always appears to be busy. This requires the following fix: (1) Fix this the attend queue problem by initialising conn::attend_link. And, consequently, two further fixes for things masked by the above bug: (2) Fix rxrpc_input_conn_event() to handle being invoked with a NULL sk_buff pointer - something that can now happen with the above change. (3) Fix the RXRPC_SKB_MARK_SERVICE_CONN_SECURED message to carry a pointer to the connection and a ref on it. Signed-off-by: David Howells cc: Marc Dionne cc: Jakub Kicinski cc: "David S.

Pull rv and tools/rtla updates from Steven Rostedt: - Add a test suite to test the tool Add a small test suite that can be used to test rtla's basic features to at least have something to test when applying changes. - Automate manual steps in monitor creation While creating a new monitor in RV, besides generating code from dot2k, there are a few manual steps which can be tedious and error prone, like adding the tracepoints, makefile lines and kconfig, or selecting events that start the monitor in the initial state. Updates were made to try and automate as much as possible among those steps to make creating a new RV monitor much quicker. It is still requires to select proper tracepoints, this step is harder to automate in a general way and, in several cases, would still need user intervention. - Have rtla timerlat hist and top set OSNOISE_WORKLOAD flag Have both rtla-timerlat-hist and rtla-timerlat-top set OSNOISE_WORKLOAD to the proper value ("on" when running with -k, "off" when running with -u) every time the option is available instead of setting it only when running with -u. This prevents rtla timerlat -k from giving no results when NO_OSNOISE_WORKLOAD is set, either manually or by an abnormally exited earlier run of rtla timerlat -u. - Stop rtla timerlat on signal properly when overloaded There is an issue where if rtla is run on machines with a high number of CPUs (100+), timerlat can generate more samples than rtla is able to process via tracefs_iterate_raw_events. This is especially common when the interval is set to 100us (rteval and cyclictest default) as opposed to the rtla default of 1000us, but also happens with the rtla default. Currently, this leads to rtla hanging and having to be terminated with SIGTERM. SIGINT setting stop_tracing is not enough, since more and more events are coming and tracefs_iterate_raw_events never exits. To fix this: Stop the timerlat tracer on SIGINT/SIGALRM to ensure no more events are generated when rtla is supposed to exit. Also on receiving SIGINT/SIGALRM twice, abort iteration immediately with tracefs_iterate_stop, making rtla exit right away instead of waiting for all events to be processed. - Account for missed events Due to tracefs buffer overflow, it can happen that rtla misses events, making the tracing results inaccurate. Count both the number of missed events and the total number of processed events, and display missed events as well as their percentage. The numbers are displayed for both osnoise and timerlat, even though for the earlier, missed events are generally not expected. For hist, the number is displayed at the end of the run; for top, it is displayed on each printing of the top table. - Changes to make osnoise more robust There was a dependency in the code that the first field of the osnoise_tool structure was the trace field. If that that ever changed, then the code work break. Change the code to encapsulate this dependency where the code that uses the structure does not have this dependency. * tag 'trace-tools-v6.14' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace: (22 commits) rtla: Report missed event count rtla: Add function to report missed events rtla: Count all processed events rtla: Count missed trace events tools/rtla: Add osnoise_trace_is_off() rtla/timerlat_top: Set OSNOISE_WORKLOAD for kernel threads rtla/timerlat_hist: Set OSNOISE_WORKLOAD for kernel threads rtla/osnoise: Distinguish missing workload option rtla/timerlat_top: Abort event processing on second signal rtla/timerlat_hist: Abort event processing on second signal rtla/timerlat_top: Stop timerlat tracer on signal rtla/timerlat_hist: Stop timerlat tracer on signal rtla: Add trace_instance_stop tools/rtla: Add basic test suite verification/dot2k: Implement event type detection verification/dot2k: Auto patch current kernel source verification/dot2k: Simplify manual steps in monitor creation rv: Simplify manual steps in monitor creation verification/dot2k: Add support for name and description options verification/dot2k: More robust template variables ...

Pull networking updates from Paolo Abeni: "This is slightly smaller than usual, with the most interesting work being still around RTNL scope reduction. Core: - More core refactoring to reduce the RTNL lock contention, including preparatory work for the per-network namespace RTNL lock, replacing RTNL lock with a per device-one to protect NAPI-related net device data and moving synchronize_net() calls outside such lock. - Extend drop reasons usage, adding net scheduler, AF_UNIX, bridge and more specific TCP coverage. - Reduce network namespace tear-down time by removing per-subsystems synchronize_net() in tipc and sched. - Add flow label selector support for fib rules, allowing traffic redirection based on such header field. Netfilter: - Do not remove netdev basechain when last device is gone, allowing netdev basechains without devices. - Revisit the flowtable teardown strategy, dealing better with fin, reset and re-open events. - Scale-up IP-vs connection dumping by avoiding linear search on each restart. Protocols: - A significant XDP socket refactor, consolidating and optimizing several helpers into the core - Better scaling of ICMP rate-limiting, by removing false-sharing in inet peers handling. - Introduces netlink notifications for multicast IPv4 and IPv6 address changes. - Add ipsec support for IP-TFS/AggFrag encapsulation, allowing aggregation and fragmentation of the inner IP. - Add sysctl to configure TIME-WAIT reuse delay for TCP sockets, to avoid local port exhaustion issues when the average connection lifetime is very short. - Support updating keys (re-keying) for connections using kernel TLS (for TLS 1.3 only). - Support ipv4-mapped ipv6 address clients in smc-r v2. - Add support for jumbo data packet transmission in RxRPC sockets, gluing multiple data packets in a single UDP packet. - Support RxRPC RACK-TLP to manage packet loss and retransmission in conjunction with the congestion control algorithm. Driver API: - Introduce a unified and structured interface for reporting PHY statistics, exposing consistent data across different H/W via ethtool. - Make timestamping selectable, allow the user to select the desired hwtstamp provider (PHY or MAC) administratively. - Add support for configuring a header-data-split threshold (HDS) value via ethtool, to deal with partial or buggy H/W implementation. - Consolidate DSA drivers Energy Efficiency Ethernet support. - Add EEE management to phylink, making use of the phylib implementation. - Add phylib support for in-band capabilities negotiation. - Simplify how phylib-enabled mac drivers expose the supported interfaces. Tests and tooling: - Make the YNL tool package-friendly to make it easier to deploy it separately from the kernel. - Increase TCP selftest coverage importing several packetdrill test-cases. - Regenerate the ethtool uapi header from the YNL spec, to ease maintenance and future development. - Add YNL support for decoding the link types used in net self-tests, allowing a single build to run both net and drivers/net. Drivers: - Ethernet high-speed NICs: - nVidia/Mellanox (mlx5): - add cross E-Switch QoS support - add SW Steering support for ConnectX-8 - implement support for HW-Managed Flow Steering, improving the rule deletion/insertion rate - support for multi-host LAG - Intel (ixgbe, ice, igb): - ice: add support for devlink health events - ixgbe: add initial support for E610 chipset variant - igb: add support for AF_XDP zero-copy - Meta: - add support for basic RSS config - allow changing the number of channels - add hardware monitoring support - Broadcom (bnxt): - implement TCP data split and HDS threshold ethtool support, enabling Device Memory TCP. - Marvell Octeon: - implement egress ipsec offload support for the cn10k family - Hisilicon (HIBMC): - implement unicast MAC filtering - Ethernet NICs embedded and virtual: - Convert UDP tunnel drivers to NETDEV_PCPU_STAT_DSTATS, avoiding contented atomic operations for drop counters - Freescale: - quicc: phylink conversion - enetc: support Tx and Rx checksum offload and improve TSO performances - MediaTek: - airoha: introduce support for ETS and HTB Qdisc offload - Microchip: - lan78XX USB: preparation work for phylink conversion - Synopsys (stmmac): - support DWMAC IP on NXP Automotive SoCs S32G2xx/S32G3xx/S32R45 - refactor EEE support to leverage the new driver API - optimize DMA and cache access to increase raw RX performances by 40% - TI: - icssg-prueth: add multicast filtering support for VLAN interface - netkit: - add ability to configure head/tailroom - VXLAN: - accepts packets with user-defined reserved bit - Ethernet switches: - Microchip: - lan969x: add RGMII support - lan969x: improve TX and RX performance using the FDMA engine - nVidia/Mellanox: - move Tx header handling to PCI driver, to ease XDP support - Ethernet PHYs: - Texas Instruments DP83822: - add support for GPIO2 clock output - Realtek: - 8169: add support for RTL8125D rev.b - rtl822x: add hwmon support for the temperature sensor - Microchip: - add support for RDS PTP hardware - consolidate periodic output signal generation - CAN: - several DT-bindings to DT schema conversions - tcan4x5x: - add HW standby support - support nWKRQ voltage selection - kvaser: - allowing Bus Error Reporting runtime configuration - WiFi: - the on-going Multi-Link Operation (MLO) effort continues, affecting both the stack and in drivers - mac80211/cfg80211: - Emergency Preparedness Communication Services (EPCS) station mode support - support for adding and removing station links for MLO - add support for WiFi 7/EHT mesh over 320 MHz channels - report Tx power info for each link - RealTek (rtw88): - enable USB Rx aggregation and USB 3 to improve performance - LED support - RealTek (rtw89): - refactor power save to support Multi-Link Operations - add support for RTL8922AE-VS variant - MediaTek (mt76): - single wiphy multiband support (preparation for MLO) - p2p device support - add TP-Link TXE50UH USB adapter support - Qualcomm (ath10k): - support for the QCA6698AQ IP core - Qualcomm (ath12k): - enable MLO for QCN9274 - Bluetooth: - Allow sysfs to trigger hdev reset, to allow recovering devices not responsive from user-space - MediaTek: add support for MT7922, MT7925, MT7921e devices - Realtek: add support for RTL8851BE devices - Qualcomm: add support for WCN785x devices - ISO: allow BIG re-sync" * tag 'net-next-6.14' of git://git.kernel.org/pub/scm/linux/kernel/git/netdev/net-next: (1386 commits) net/rose: prevent integer overflows in rose_setsockopt() net: phylink: fix regression when binding a PHY net: ethernet: ti: am65-cpsw: streamline TX queue creation and cleanup net: ethernet: ti: am65-cpsw: streamline RX queue creation and cleanup net: ethernet: ti: am65-cpsw: ensure proper channel cleanup in error path ipv6: Convert inet6_rtm_deladdr() to per-netns RTNL. ipv6: Convert inet6_rtm_newaddr() to per-netns RTNL. ipv6: Move lifetime validation to inet6_rtm_newaddr(). ipv6: Set cfg.ifa_flags before device lookup in inet6_rtm_newaddr(). ipv6: Pass dev to inet6_addr_add(). ipv6: Convert inet6_ioctl() to per-netns RTNL. ipv6: Hold rtnl_net_lock() in addrconf_init() and addrconf_cleanup(). ipv6: Hold rtnl_net_lock() in addrconf_dad_work(). ipv6: Hold rtnl_net_lock() in addrconf_verify_work(). ipv6: Convert net.ipv6.conf.${DEV}.XXX sysctl to per-netns RTNL. ipv6: Add __in6_dev_get_rtnl_net(). net: stmmac: Drop redundant skb_mark_for_recycle() for SKB frags net: mii: Fix the Speed display when the network cable is not connected sysctl net: Remove macro checks for CONFIG_SYSCTL eth: bnxt: update header sizing defaults ...

Pull btrfs updates from David Sterba: "User visible changes, features: - rebuilding of the free space tree at mount time is done in more transactions, fix potential hangs when the transaction thread is blocked due to large amount of block groups - more read IO balancing strategies (experimental config), add two new ways how to select a device for read if the profiles allow that (all RAID1*), the current default selects the device by pid which is good on average but less performant for single reader workloads - select preferred device for all reads (namely for testing) - round-robin, balance reads across devices relevant for the requested IO range - add encoded write ioctl support to io_uring (read was added in 6.12), basis for writing send stream using that instead of syscalls, non-blocking mode is not yet implemented - support FS_IOC_READ_VERITY_METADATA, applications can use the metadata to do their own verification - pass inode's i_write_hint to bios, for parity with other filesystems, ioctls F_GET_RW_HINT/F_SET_RW_HINT Core: - in zoned mode: allow to directly reclaim a block group by simply resetting it, then it can be reused and another block group does not need to be allocated - super block validation now also does more comprehensive sys array validation, adding it to the points where superblock is validated (post-read, pre-write) - subpage mode fixes: - fix double accounting of blocks due to some races - improved or fixed error handling in a few cases (compression, delalloc) - raid stripe tree: - fix various cases with extent range splitting or deleting - implement hole punching to extent range - reduce number of stripe tree lookups during bio submission - more self-tests - updated self-tests (delayed refs) - error handling improvements - cleanups, refactoring - remove rest of backref caching infrastructure from relocation, not needed anymore - error message updates - remove unnecessary calls when extent buffer was marked dirty - unused parameter removal - code moved to new files Other code changes: add rb_find_add_cached() to the rb-tree API" * tag 'for-6.14-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/kdave/linux: (127 commits) btrfs: selftests: add a selftest for deleting two out of three extents btrfs: selftests: add test for punching a hole into 3 RAID stripe-extents btrfs: selftests: add selftest for punching holes into the RAID stripe extents btrfs: selftests: test RAID stripe-tree deletion spanning two items btrfs: selftests: don't split RAID extents in half btrfs: selftests: check for correct return value of failed lookup btrfs: don't use btrfs_set_item_key_safe on RAID stripe-extents btrfs: implement hole punching for RAID stripe extents btrfs: fix deletion of a range spanning parts two RAID stripe extents btrfs: fix tail delete of RAID stripe-extents btrfs: fix front delete range calculation for RAID stripe extents btrfs: assert RAID stripe-extent length is always greater than 0 btrfs: don't try to delete RAID stripe-extents if we don't need to btrfs: selftests: correct RAID stripe-tree feature flag setting btrfs: add io_uring interface for encoded writes btrfs: remove the unused locked_folio parameter from btrfs_cleanup_ordered_extents() btrfs: add extra error messages for delalloc range related errors btrfs: subpage: dump the involved bitmap when ASSERT() failed btrfs: subpage: fix the bitmap dump of the locked flags btrfs: do proper folio cleanup when run_delalloc_nocow() failed ...
