2023-07-26virtio-net: fix race between set queues and probeJason Wang1-2/+2
A race were found where set_channels could be called after registering but before virtnet_set_queues() in virtnet_probe(). Fixing this by moving the virtnet_set_queues() before netdevice registering. While at it, use _virtnet_set_queues() to avoid holding rtnl as the device is not even registered at that time.

2023-07-26net/sched: mqprio: Add length check for TCA_MQPRIO_{MAX/MIN}_RATE64Lin Ma1-0/+14
The nla_for_each_nested parsing in function mqprio_parse_nlattr() does not check the length of the nested attribute. This can lead to an out-of-attribute read and allow a malformed nlattr (e.g., length 0) to be viewed as 8 byte integer and passed to priv->max_rate/min_rate. This patch adds the check based on nla_len() when check the nla_type(), which ensures that the length of these two attribute must equals sizeof(u64).

2023-07-26splice, net: Fix splice_to_socket() for O_NONBLOCK socketJan Stancek1-0/+2
LTP sendfile07 [1], which expects sendfile() to return EAGAIN when transferring data from regular file to a "full" O_NONBLOCK socket, started failing after commit 2dc334f1a63a ("splice, net: Use sendmsg(MSG_SPLICE_PAGES) rather than ->sendpage()"). sendfile() no longer immediately returns, but now blocks.

According to the clarification [1] in the latest napi.rst, the tx processing cannot call any XDP (or page pool) APIs if the "budget" is 0.

2023-07-26net/mlx5e: kTLS, Fix protection domain in use syndrome when devlink reloadJianbo Liu2-11/+26
There are DEK objects cached in DEK pool after kTLS is used, and they are freed only in mlx5e_ktls_cleanup(). mlx5e_destroy_mdev_resources() is called in mlx5e_suspend() to free mdev resources, including protection domain (PD). However, PD is still referenced by the cached DEK objects in this case, because profile->cleanup() (and therefore mlx5e_ktls_cleanup()) is called after mlx5e_suspend() during devlink reload. So the following FW syndrome is generated: mlx5_cmd_out_err:803:(pid 12948): DEALLOC_PD(0x801) op_mod(0x0) failed, status bad resource state(0x9), syndrome (0xef0c8a), err(-22) To avoid this syndrome, move DEK pool destruction to mlx5e_ktls_cleanup_tx(), which is called by profile->cleanup_tx(). And move pool creation to mlx5e_ktls_init_tx() for symmetry.

2023-07-26net/mlx5e: xsk: Fix crash on regular rq reactivationDragos Tatulea1-8/+21
When the regular rq is reactivated after the XSK socket is closed it could be reading stale cqes which eventually corrupts the rq. This leads to no more traffic being received on the regular rq and a crash on the next close or deactivation of the rq. Kal Cuttler Conely reported this issue as a crash on the release path when the xdpsock sample program is stopped (killed) and restarted in sequence while traffic is running. This patch flushes all cqes when during the rq flush. The cqe flushing is done in the reset state of the rq. mlx5e_rq_to_ready code is moved into the flush function to allow for this.

2023-07-26net/mlx5e: xsk: Fix invalid buffer access for legacy rqDragos Tatulea1-1/+4
The below crash can be encountered when using xdpsock in rx mode for legacy rq: the buffer gets released in the XDP_REDIRECT path, and then once again in the driver. This fix sets the flag to avoid releasing on the driver side. XSK handling of buffers for legacy rq was relying on the caller to set the skip release flag. But the referenced fix started using fragment counts for pages instead of the skip flag.

2023-07-26net/mlx5e: Move representor neigh cleanup to profile cleanup_txJianbo Liu1-10/+7
For IP tunnel encapsulation in ECMP (Equal-Cost Multipath) mode, as the flow is duplicated to the peer eswitch, the related neighbour information on the peer uplink representor is created as well. In the cited commit, eswitch devcom unpair is moved to uplink unload API, specifically the profile->cleanup_tx. If there is a encap rule offloaded in ECMP mode, when one eswitch does unpair (because of unloading the driver, for instance), and the peer rule from the peer eswitch is going to be deleted, the use-after-free error is triggered while accessing neigh info, as it is already cleaned up in uplink's profile->disable, which is before its profile->cleanup_tx. To fix this issue, move the neigh cleanup to profile's cleanup_tx callback, and after mlx5e_cleanup_uplink_rep_tx is called. The neigh init is moved to init_tx for symmeter.

2023-07-26mm: suppress mm fault logging if fatal signal already pendingLinus Torvalds1-0/+4
Commit eda0047296a1 ("mm: make the page fault mmap locking killable") intentionally made it much easier to trigger the "page fault fails because a fatal signal is pending" situation, by having the mmap locking fail early in that case. We have long aborted page faults in other fatal cases when the actual IO for a page is interrupted by SIGKILL - which is particularly useful for the traditional case of NFS hanging due to network issues, but local filesystems could cause it too if you happened to get the SIGKILL while waiting for a page to be faulted in (eg lock_folio_maybe_drop_mmap()). So aborting the page fault wasn't a new condition - but it now triggers earlier, before we even get to 'handle_mm_fault()'. And as a result the error doesn't go through our 'fault_signal_pending()' logic, and doesn't get filtered away there. Normally you'd never even notice, because if a fatal signal is pending, the new SIGSEGV we send ends up being ignored anyway. But it turns out that there is one very noticeable exception: if you enable 'show_unhandled_signals', the aborted page fault will be logged in the kernel messages, and you'll get a scary line looking something like this in your logs: pverados[2183248]: segfault at 55e5a00f9ae0 ip 000055e5a00f9ae0 sp 00007ffc0720bea8 error 14 in perl[55e5a00d4000+195000] likely on CPU 10 (core 4, socket 0) which is rather misleading. It's not really a segfault at all, it's just "the thread was killed before the page fault completed, so we aborted the page fault". Fix this by just making it clear that a pending fatal signal means that any new signal coming in after that is implicitly handled. This will avoid the misleading logging, since now the signal isn't 'unhandled' any more.

2023-07-26arm64/sme: Set new vector length before reallocatingMark Brown1-2/+2
As part of fixing the allocation of the buffer for SVE state when changing SME vector length we introduced an immediate reallocation of the SVE state, this is also done when changing the SVE vector length for consistency. Unfortunately this reallocation is done prior to writing the new vector length to the task struct, meaning the allocation is done with the old vector length and can lead to memory corruption due to an undersized buffer being used. Move the update of the vector length before the allocation to ensure that the new vector length is taken into account. For some reason this isn't triggering any problems when running tests on the arm64 fixes branch (even after repeated tries) but is triggering issues very often after merge into mainline.

2023-07-26arm64/fpsimd: Don't flush SME register hardware state along with threadMark Brown1-1/+0
We recently changed the fpsimd thread flush to flush the physical SME state as well as the thread state for the current thread. Unfortunately this leads to intermittent corruption in interaction with the lazy FPSIMD register switching. When under heavy load such as can be triggered by the startup phase of fp-stress it is possible that the current thread may not be scheduled prior to returning to userspace, and indeed we may end up returning to the last thread that was scheduled on the PE without ever exiting the kernel to any other task. If that happens then we will not reload the register state from memory, leading to loss of any SME register state. Since this was purely an attempt to defensively close off potential problems revert the change.

Factor out the code that decides whether to write to the feature trap registers, CPTR_EL2 or CPACR_EL1, based on the KVM mode, i.e., (h)VHE or nVHE.
