2024-02-15kallsyms: ignore ARMv4 thunks along with othersArnd Bergmann
lld is now able to build ARMv4 and ARMv4T kernels, which means it can generate thunks for those (__ARMv4PILongThunk_*, __ARMv4PILongBXThunk_*) that can interfere with kallsyms table generation since they do not get ignore like the corresponding ARMv5+ ones are: Inconsistent kallsyms data Try "make KALLSYMS_EXTRA_PASS=1" as a workaround Replace the hardcoded list of thunk symbols with a more general regex that covers this one along with future symbols that follow the same pattern.

2024-02-15net: bcmasp: Handle RX buffer allocation failureFlorian Fainelli
The buffer_pg variable needs to hold an order-5 allocation (32 x PAGE_SIZE) which, under memory pressure may fail to be allocated. Deal with that error condition properly to avoid doing a NULL pointer de-reference in the subsequent call to dma_map_page(). In addition, the err_reclaim_tx error label in bcmasp_netif_init() needs to ensure that the TX NAPI object is properly deleted, otherwise unregister_netdev() will spin forever attempting to test and clear the NAPI_STATE_HASHED bit.

2024-02-15arm64/sve: Lower the maximum allocation for the SVE ptrace regsetMark Brown
Doug Anderson observed that ChromeOS crashes are being reported which include failing allocations of order 7 during core dumps due to ptrace allocating storage for regsets: chrome: page allocation failure: order:7, mode:0x40dc0(GFP_KERNEL|__GFP_COMP|__GFP_ZERO), nodemask=(null),cpuset=urgent,mems_allowed=0 ... regset_get_alloc+0x1c/0x28 elf_core_dump+0x3d8/0xd8c do_coredump+0xeb8/0x1378 with further investigation showing that this is: [ 66.957385] DOUG: Allocating 279584 bytes which is the maximum size of the SVE regset. As Doug observes it is not entirely surprising that such a large allocation of contiguous memory might fail on a long running system. The SVE regset is currently sized to hold SVE registers with a VQ of SVE_VQ_MAX which is 512, substantially more than the architectural maximum of 16 which we might see even in a system emulating the limits of the architecture. Since we don't expose the size we tell the regset core externally let's define ARCH_SVE_VQ_MAX with the actual architectural maximum and use that for the regset, we'll still overallocate most of the time but much less so which will be helpful even if the core is fixed to not require contiguous allocations. Specify ARCH_SVE_VQ_MAX in terms of the maximum value that can be written into ZCR_ELx.LEN (where this is set in the hardware). For consistency update the maximum SME vector length to be specified in the same style while we are at it. We could also teach the ptrace core about runtime discoverable regset sizes but that would be a more invasive change and this is being observed in practical systems.

2024-02-15net-timestamp: make sk_tskey more predictable in error pathVadim Fedorenko
When SOF_TIMESTAMPING_OPT_ID is used to ambiguate timestamped datagrams, the sk_tskey can become unpredictable in case of any error happened during sendmsg(). Move increment later in the code and make decrement of sk_tskey in error path. This solution is still racy in case of multiple threads doing snedmsg() over the very same socket in parallel, but still makes error path much more predictable.

The function xe_vm_prepare_vma was blindly accepting zero as the number of fences and forwarded that to drm_exec_prepare_obj.

2024-02-14io_uring/net: fix multishot accept overflow handlingJens Axboe
If we hit CQ ring overflow when attempting to post a multishot accept completion, we don't properly save the result or return code. This results in losing the accepted fd value. Instead, we return the result from the poll operation that triggered the accept retry. This is generally POLLIN|POLLPRI|POLLRDNORM|POLLRDBAND which is 0xc3, or 195, which looks like a valid file descriptor, but it really has no connection to that. Handle this like we do for other multishot completions - assign the result, and return IOU_STOP_MULTISHOT to cancel any further completions from this request when overflow is hit. This preserves the result, as we should, and tells the application that the request needs to be re-armed.

2024-02-14drm/i915/gt: Restart the heartbeat timer when forcing a pulseJohn Harrison
The context persistence code does things like send super high priority heartbeat pulses to ensure any leaked context can still be pre-empted and thus isn't a total denial of service but only a minor denial of service. Unfortunately, it wasn't bothering to restart the heartbeat worker with a fresh timeout. Thus, if a persistent context happened to be closed just before the heartbeat was going to go ping anyway then the forced pulse would get a negligble execution time. And as the forced pulse is super high priority, the worker thread's next step is a reset. Which means a potentially innocent system randomly goes boom when attempting to close a context. So, force a re-schedule of the worker thread with the appropriate timeout.

2024-02-15drm/i915: Enable fastboot across the boardVille Syrjälä
There's nothing magical about vlv+ platforms vs. fastboot. If it works somewhere it should work everywhere, assuming we've not missed any crucial state checks. That seems unlikely on older platforms with less state to check anyway. Just enable fastboot across the board, and the remove the remnants of the optional stuff (we already removed the modparam for fastboot anyway).

2024-02-15netfilter: nat: restore default DNAT behaviorKyle Swenson
When a DNAT rule is configured via iptables with different port ranges, iptables -t nat -A PREROUTING -p tcp -d 10.0.0.2 -m tcp --dport 32000:32010 -j DNAT --to-destination 192.168.0.10:21000-21010 we seem to be DNATing to some random port on the LAN side. While this is expected if --random is passed to the iptables command, it is not expected without passing --random. The expected behavior (and the observed behavior prior to the commit in the "Fixes" tag) is the traffic will be DNAT'd to 192.168.0.10:21000 unless there is a tuple collision with that destination. In that case, we expect the traffic to be instead DNAT'd to 192.168.0.10:21001, so on so forth until the end of the range. This patch intends to restore the behavior observed prior to the "Fixes" tag.
