This API was intended to generate large 64 byte MemWr TLPs on PCI. These days most processors had done this by just repeating writel() in a loop. S390 and some new ARM64 designs require a special helper to get this to generate. - Small improvements and fixes for erdma, efa, hfi1, bnxt_re - Fix a UAF crash after module unload on leaking restrack entry - Continue adding full RDMA support in mana with support for EQs, GID's and CQs - Improvements to the mkey cache in mlx5 - DSCP traffic class support in hns and several bug fixes - Cap the maximum number of MADs in the receive queue to avoid OOM - Another batch of rxe bug fixes from large scale testing - __iowrite64_copy() optimizations for write combining MMIO memory - Remove NULL checks before dev_put/hold() - EFA support for receive with immediate - Fix a recent memleaking regression in a cma error path" * tag 'for-linus' of git://git.kernel.org/pub/scm/linux/kernel/git/rdma/rdma: (70 commits) RDMA/cma: Fix kmemleak in rdma_core observed during blktests nvme/rdma use siw RDMA/IPoIB: Fix format truncation compilation errors bnxt_re: avoid shift undefined behavior in bnxt_qplib_alloc_init_hwq RDMA/efa: Support QP with unsolicited write w/ imm. receive IB/hfi1: Remove generic .ndo_get_stats64 IB/hfi1: Do not use custom stat allocator RDMA/hfi1: Use RMW accessors for changing LNKCTL2 RDMA/mana_ib: implement uapi for creation of rnic cq RDMA/mana_ib: boundary check before installing cq callbacks RDMA/mana_ib: introduce a helper to remove cq callbacks RDMA/mana_ib: create and destroy RNIC cqs RDMA/mana_ib: create EQs for RNIC CQs RDMA/core: Remove NULL check before dev_{put, hold} RDMA/ipoib: Remove NULL check before dev_{put, hold} RDMA/mlx5: Remove NULL check before dev_{put, hold} RDMA/mlx5: Track DCT, DCI and REG_UMR QPs as diver_detail resources.

Linus Torvalds	619b92b9c8	I'm actually surprised this time. There aren't any new Qualcomm SoC clk ... drivers. And there's zero diff in the core clk framework. Instead we have new clk drivers for STM and Sophgo, with Samsung^WGoogle in third for the diffstat because they introduced HSI0 and HSI2 clk drivers for Google's GS101 SoC (high speed interface things like PCIe, UFS, and MMC). Beyond those big diffs there's the usual updates to various clk drivers for incorrect parent descriptions or mising MODULE_DEVICE_TABLE()s, etc. Nothing in particular stands out as super interesting here.

Linus Torvalds	fa3889d970	user-event updates for v6.10: ... - Minor update to the user_events interface The ABI of creating a user event states that the fields are separated by semicolons, and spaces should be ignored. But the parsing expected at least one space to be there (which was incorrect). Fix the reading of the string to handle fields separated by semicolons but no space between them. This does extend the API sightly as now "field;field" will now be parsed and not cause an error. But it should not cause any regressions as no logic should expect it to fail.

Linus Torvalds	53683e4080	tracing ring buffer updates for v6.10: ... - Add ring_buffer memory mappings The tracing ring buffer was created based on being mostly used with the splice system call. It is broken up into page ordered sub-buffers and the reader swaps a new sub-buffer with an existing sub-buffer that's part of the write buffer. It then has total access to the swapped out sub-buffer and can do copyless movements of the memory into other mediums (file system, network, etc). The buffer is great for passing around the ring buffer contents in the kernel, but is not so good for when the consumer is the user space task itself. A new interface is added that allows user space to memory map the ring buffer. It will get all the write sub-buffers as well as reader sub-buffer (that is not written to). It can send an ioctl to change which sub-buffer is the new reader sub-buffer. The ring buffer is read only to user space. It only needs to call the ioctl when it is finished with a sub-buffer and needs a new sub-buffer that the writer will not write over. A self test program was also created for testing and can be used as an example for the interface to user space. The libtracefs (external to the kernel) also has code that interacts with this, although it is disabled until the interface is in a official release. It can be enabled by compiling the library with a special flag. This was used for testing applications that perform better with the buffer being mapped. Memory mapped buffers have limitations. The main one is that it can not be used with the snapshot logic. If the buffer is mapped, snapshots will be disabled. If any logic is set to trigger snapshots on a buffer, that buffer will not be allowed to be mapped. -----BEGIN PGP SIGNATURE----- iIoEABYIADIWIQRRSw7ePDh/lE+zeZMp5XQQmuv6qgUCZkYzDRQccm9zdGVkdEBn b29kbWlzLm9yZwAKCRAp5XQQmuv6qttNAQCj3I0OpeI1vms85ShIa7Eha2qes5uC Yml2fnapkmRSwAEAp5UTGxtDctycWOk9B9PA7/oJmLgATaQwRKoEeTUwfAA= =TyEB -----END PGP SIGNATURE----- Merge tag 'trace-ringbuffer-v6.10' of git://git.kernel.org/pub/scm/linux/kernel/git/trace/linux-trace Pull tracing ring buffer updates from Steven Rostedt: "Add ring_buffer memory mappings.

Tom Parkin	6e828dc60e	l2tp: fix ICMP error handling for UDP-encap sockets ... Since commit a36e185e8c85 ("udp: Handle ICMP errors for tunnels with same destination port on both endpoints") UDP's handling of ICMP errors has allowed for UDP-encap tunnels to determine socket associations in scenarios where the UDP hash lookup could not. Subsequently, commit d26796ae58940 ("udp: check udp sock encap_type in __udp_lib_err") subtly tweaked the approach such that UDP ICMP error handling would be skipped for any UDP socket which has encapsulation enabled. In the case of L2TP tunnel sockets using UDP-encap, this latter modification effectively broke ICMP error reporting for the L2TP control plane. To a degree this isn't catastrophic inasmuch as the L2TP control protocol defines a reliable transport on top of the underlying packet switching network which will eventually detect errors and time out. However, paying attention to the ICMP error reporting allows for more timely detection of errors in L2TP userspace, and aids in debugging connectivity issues. Reinstate ICMP error handling for UDP encap L2TP tunnels: * implement struct udp_tunnel_sock_cfg .encap_err_rcv in order to allow the L2TP code to handle ICMP errors; * only implement error-handling for tunnels which have a managed socket: unmanaged tunnels using a kernel socket have no userspace to report errors back to; * flag the error on the socket, which allows for userspace to get an error such as -ECONNREFUSED back from sendmsg/recvmsg; * pass the error into ip[v6]_icmp_error() which allows for userspace to get extended error information via.

Ard Biesheuvel	15aa8fb852	x86/efistub: Omit physical KASLR when memory reservations exist ... The legacy decompressor has elaborate logic to ensure that the randomized physical placement of the decompressed kernel image does not conflict with any memory reservations, including ones specified on the command line using mem=, memmap=, efi_fake_mem= or hugepages=, which are taken into account by the kernel proper at a later stage. When booting in EFI mode, it is the firmware's job to ensure that the chosen range does not conflict with any memory reservations that it knows about, and this is trivially achieved by using the firmware's memory allocation APIs. That leaves reservations specified on the command line, though, which the firmware knows nothing about, as these regions have no other special significance to the platform. Since commit a1b87d54f4e4 ("x86/efistub: Avoid legacy decompressor when doing EFI boot") these reservations are not taken into account when randomizing the physical placement, which may result in conflicts where the memory cannot be reserved by the kernel proper because its own executable image resides there. To avoid having to duplicate or reuse the existing complicated logic, disable physical KASLR entirely when such overrides are specified. These are mostly diagnostic tools or niche features, and physical KASLR (as opposed to virtual KASLR, which is much more important as it affects the memory addresses observed by code executing in the kernel) is something we can live without.

Rafael J. Wysocki	8c69a777e4	thermal: core: Fix the handling of invalid trip points ... Commit 9ad18043fb35 ("thermal: core: Send trip crossing notifications at init time if needed") overlooked the case when a trip point that has started as invalid is set to a valid temperature later. Namely, the initial threshold value for all trips is zero, so if a previously invalid trip becomes valid and its (new) low temperature is above the zone temperature, a spurious trip crossing notification will occur and it may trigger the WARN_ON() in handle_thermal_trip(). To address this, set the initial threshold for all trips to INT_MAX. There is also the case when a valid writable trip becomes invalid that requires special handling. First, in accordance with the change mentioned above, the trip's threshold needs to be set to INT_MAX to avoid the same issue. Second, if the trip in question is passive and it has been crossed by the thermal zone temperature on the way up, the zone's passive count has been incremented and it is in the passive polling mode, so its passive count needs to be adjusted to allow the passive polling to be turned off eventually.

Viresh Kumar	2a56c462fe	OPP: Fix required_opp_tables for multiple genpds using same table ... The required_opp_tables parsing is not perfect, as the OPP core does the parsing solely based on the DT node pointers. The core sets the required_opp_tables entry to the first OPP table in the "opp_tables" list, that matches with the node pointer. If the target DT OPP table is used by multiple devices and they all create separate instances of 'struct opp_table' from it, then it is possible that the required_opp_tables entry may be set to the incorrect sibling device. Unfortunately, there is no clear way to initialize the right values during the initial parsing and we need to do this at a later point of time. Cross check the OPP table again while the genpds are attached and fix them if required. Also add a new API for the genpd core to fetch the device pointer for the genpd.

In cpu_max_write(), the unit of the burst value returned by tg_get_cfs_burst() is microseconds, while in cpu_max_write(), the burst unit used for calculation should be nanoseconds, which leads to the bug. To fix it, get the burst value directly from tg->cfs_bandwidth.burst.

Dawei Li	72bffbf57c	sched/fair: Fix initial util_avg calculation ... Change se->load.weight to se_weight(se) in the calculation for the initial util_avg to avoid unnecessarily inflating the util_avg by 1024 times. The reason is that se->load.weight has the unit/scale as the scaled-up load, while cfs_rg->avg.load_avg has the unit/scale as the true task weight (as mapped directly from the task's nice/priority value). With CONFIG_32BIT, the scaled-up load is equal to the true task weight. With CONFIG_64BIT, the scaled-up load is 1024 times the true task weight. Thus, the current code may inflate the util_avg by 1024 times. The follow-up capping will not allow the util_avg value to go wild. But the calculation should have the correct logic.

Borislav Petkov (AMD)	9dba9c67e5	x86/alternatives: Use the correct length when optimizing NOPs ... Commit in Fixes moved the optimize_nops() call inside apply_relocation() and made it a second optimization pass after the relocations have been done. Since optimize_nops() works only on NOPs, that is fine and it'll simply jump over instructions which are not NOPs. However, it made that call with repl_len as the buffer length to optimize. However, it can happen that there are alternatives calls like this one: alternative("mfence; lfence", "", ALT_NOT(X86_FEATURE_APIC_MSRS_FENCE)); where the replacement length is 0. And using repl_len is wrong because apply_alternatives() expands the buffer size to the length of the source insn that is being patched, by padding it with one-byte NOPs: for (; insn_buff_sz < a->instrlen; insn_buff_sz++) insn_buff[insn_buff_sz] = 0x90; Long story short: pass the length of the original instruction(s) as the length of the temporary buffer which to optimize.
