commit 6f6cb171 upstream. Patch series "Fix a bunch of allmodconfig errors", v2. Since b339ec9c ("kbuild: Only default to -Werror if COMPILE_TEST") WERROR now defaults to COMPILE_TEST meaning that it's enabled for allmodconfig builds. This leads to some interesting build failures when using Clang, each resolved in this set. With this set applied, I am able to obtain a successful allmodconfig Arm build. This patch (of 2): calculate_bandwidth() is presently broken on all !(X86_64 || SPARC64 || ARM64) architectures built with Clang (all released versions), whereby the stack frame gets blown up to well over 5k. This would cause an immediate kernel panic on most architectures. We'll revert this when the following bug report has been resolved: https://github.com/llvm/llvm-project/issues/41896.

commit c981cdfb upstream. Commit 20b92a30 ("mmc: sdhci: update signal voltage switch code") removed voltage switch delays from sdhci because mmc core had been enhanced to support them. However that assumed that sdhci_set_ios() did a single clock change, which it did not, and so the delays in mmc core, which should have come after the first clock change, were not effective. Fix by avoiding re-configuring UHS and preset settings when the clock is turning on and the settings have not changed. That then also avoids the associated clock changes, so that then sdhci_set_ios() does a single clock change when voltage switching, and the mmc core delays become effective. To do that has meant keeping track of driver strength (host->drv_type), and cases of reinitialization (host->reinit_uhs). Note also, the 'turning_on_clk' restriction should not be necessary but is done to minimize the impact of the change on stable kernels.

commit a3cab1d2 upstream. With the current logic the "failed to exit halt state" error would be shown even if any other bit than CQHCI_HALT was set in the CQHCI_CTL register, since the right hand side is always true.

commit 829ae0f8 upstream. The issue is reported when removing memory through virtio_mem device. The transparent huge page, experienced copy-on-write fault, is wrongly regarded as pinned. The transparent huge page is escaped from being isolated in isolate_migratepages_block(). The transparent huge page can't be migrated and the corresponding memory block can't be put into offline state. Fix it by replacing page_mapcount() with total_mapcount(). With this, the transparent huge page can be isolated and migrated, and the memory block can be put into offline state. Besides, The page's refcount is increased a bit earlier to avoid the page is released when the check is executed.

commit 6647e76a upstream. The V4L2_MEMORY_USERPTR interface is long deprecated and shouldn't be used (and is discouraged for any modern v4l drivers). And Seth Jenkins points out that the fallback to VM_PFNMAP/VM_IO is fundamentally racy and dangerous. Note that it's not even a case that should trigger, since any normal user pointer logic ends up just using the pin_user_pages_fast() call that does the proper page reference counting. That's not the problem case, only if you try to use special device mappings do you have any issues. Normally I'd just remove this during the merge window, but since Seth pointed out the problem cases, we really want to know as soon as possible if there are actually any users of this odd special case of a legacy interface. Neither Hans nor Mauro seem to think that such mis-uses of the old legacy interface should exist. As Mauro says: "See, V4L2 has actually 4 streaming APIs: - Kernel-allocated mmap (usually referred simply as just mmap); - USERPTR mmap; - read(); - dmabuf; The USERPTR is one of the oldest way to use it, coming from V4L version 1 times, and by far the least used one" And Hans chimed in on the USERPTR interface: "To be honest, I wouldn't mind if it goes away completely, but that's a bit of a pipe dream right now" but while removing this legacy interface entirely may be a pipe dream we can at least try to remove the unlikely (and actively broken) case of using special device mappings for USERPTR accesses. This replaces it with a WARN_ONCE() that we can remove once we've hopefully confirmed that no actual users exist. NOTE! Longer term, this means that a 'struct frame_vector' only ever contains proper page pointers, and all the games we have with converting them to pages can go away (grep for 'frame_vector_to_pages()' and the uses of 'vec->is_pfns'). But this is just the first step, to verify that this code really is all dead, and do so as quickly as possible. Reported-by:

commit 6989ea48 upstream. The firmware on some systems may configure GPIO pins to be an interrupt source in so called "direct IRQ" mode. In such cases the GPIO controller driver has no idea if those pins are being used or not. At the same time, there is a known bug in the firmwares that don't restore the pin settings correctly after suspend, i.e. by an unknown reason the Rx value becomes inverted. Hence, let's save and restore the pins that are configured as GPIOs in the input mode with GPIROUTIOXAPIC bit set. Cc: stable@vger.kernel.org Reported-and-tested-by:

commit 66065157 upstream. The "force" argument to write_spec_ctrl_current() is currently ambiguous as it does not guarantee the MSR write. This is due to the optimization that writes to the MSR happen only when the new value differs from the cached value. This is fine in most cases, but breaks for S3 resume when the cached MSR value gets out of sync with the hardware MSR value due to S3 resetting it. When x86_spec_ctrl_current is same as x86_spec_ctrl_base, the MSR write is skipped. Which results in SPEC_CTRL mitigations not getting restored. Move the MSR write from write_spec_ctrl_current() to a new function that unconditionally writes to the MSR. Update the callers accordingly and rename functions.

commit a4412fdd upstream. The config to be able to inject error codes into any function annotated with ALLOW_ERROR_INJECTION() is enabled when FUNCTION_ERROR_INJECTION is enabled. But unfortunately, this is always enabled on x86 when KPROBES is enabled, and there's no way to turn it off. As kprobes is useful for observability of the kernel, it is useful to have it enabled in production environments. But error injection should be avoided. Add a prompt to the config to allow it to be disabled even when kprobes is enabled, and get rid of the "def_bool y". This is a kernel debug feature (it's in Kconfig.debug), and should have never been something enabled by default.

commit 6fdd5d2f upstream. 64-bit RISC-V kernels have the kernel image mapped separately to alias the linear map. The linear map and the kernel image map are documented as "direct mapping" and "kernel" respectively in [1]. At image load time, the linear map corresponding to the kernel image is set to PAGE_READ permission, and the kernel image map is set to PAGE_READ|PAGE_EXEC. When the initmem is freed, the pages in the linear map should be restored to PAGE_READ|PAGE_WRITE, whereas the corresponding pages in the kernel image map should be restored to PAGE_READ, by removing the PAGE_EXEC permission. This is not the case. For 64-bit kernels, only the linear map is restored to its proper page permissions at initmem free, and not the kernel image map. In practise this results in that the kernel can potentially jump to dead __init code, and start executing invalid instructions, without getting an exception. Restore the freed initmem properly, by setting both the kernel image map to the correct permissions.

commit 74f6bb55 upstream. lkp reported a build error, I tried the config and can reproduce build error as below: VDSOLD arch/riscv/kernel/vdso/vdso.so.dbg ld.lld: error: section .note file range overlaps with .text >>> .note range is [0x7C8, 0x803] >>> .text range is [0x800, 0x1993] ld.lld: error: section .text file range overlaps with .dynamic >>> .text range is [0x800, 0x1993] >>> .dynamic range is [0x808, 0x937] ld.lld: error: section .note virtual address range overlaps with .text >>> .note range is [0x7C8, 0x803] >>> .text range is [0x800, 0x1993] Fix it by setting DISABLE_BRANCH_PROFILING which will disable branch tracing for vdso, thus avoid useless _ftrace_annotated_branch section and _ftrace_branch section. Although we can also fix it by removing the hardcoded .text begin address, but I think that's another story and should be put into another patch.

[ Upstream commit ca57f022 ] The fileserver probing code attempts to work out the best fileserver to use for a volume by retrieving the RTT calculated by AF_RXRPC for the probe call sent to each server and comparing them. Sometimes, however, no RTT estimate is available and rxrpc_kernel_get_srtt() returns false, leading good fileservers to be given an RTT of UINT_MAX and thus causing the rotation algorithm to ignore them. Fix afs_select_fileserver() to ignore rxrpc_kernel_get_srtt()'s return value and just take the estimated RTT it provides - which will be capped at 1 second.

[ Upstream commit fe948001 ] All of the subflows of a msk will be orphaned in mptcp_close(), which means the subflows are in DEAD state. After then, DATA_FIN will be sent, and the other side will response with a DATA_ACK for this DATA_FIN. However, if the other side still has pending data, the data that received on these subflows will not be passed to the msk, as they are DEAD and subflow_data_ready() will not be called in tcp_data_ready(). Therefore, these data can't be acked, and they will be retransmitted again and again, until timeout. Fix this by setting ssk->sk_socket and ssk->sk_wq to 'NULL', instead of orphaning the subflows in __mptcp_close(), as Paolo suggested.

[ Upstream commit c34ca4f3 ] skb passed to network layer contains incorrect length. In mux aggregation protocol, the datagram block received from device contains block signature, packet & datagram header. The right skb len to be calculated by subracting datagram pad len from datagram length. Whereas in mux lite protocol, the skb contains single datagram so skb len is calculated by subtracting the packet offset from datagram header.

[ Upstream commit 2290a1d4 ] Peek throughput UL test is resulting in crash. If the UL transfer block free list is exhaust, the peeked skb is freed. In the next transfer freed skb is referred from UL list which results in crash. Don't free the skb if UL transfer blocks are unavailable. The pending skb will be picked for transfer on UL transfer block available. Fixes: 1f52d7b6 ("net: wwan: iosm: Enable M.2 7360 WWAN card support") Signed-off-by:
