Easier to see that we won't run out of array that way. Note that special treatment of the partial buffer in that thing is an artifact of the non-advancing semantics of iov_iter_get_pages() - if not for that, it would be append_pipe(), same as the body of the loop that follows it. IOW, once we make iov_iter_get_pages() advancing, the whole thing will turn into calculate how many pages do we want allocate an array (if needed) call append_pipe() that many times.

10f525a Al Viro 15 June 2022, 06:02:51 UTC ITER_PIPE: cache the type of last buffer We often need to find whether the last buffer is anon or not, and currently it's rather clumsy: check if ->iov_offset is non-zero (i.e. that pipe is not empty) if so, get the corresponding pipe_buffer and check its ->ops if it's &default_pipe_buf_ops, we have an anon buffer. Let's replace the use of ->iov_offset (which is nowhere near similar to its role for other flavours) with signed field (->last_offset), with the following rules: empty, no buffers occupied: 0 anon, with bytes up to N-1 filled: N zero-copy, with bytes up to N-1 filled: -N That way abs(i->last_offset) is equal to what used to be in i->iov_offset and empty vs. anon vs. zero-copy can be distinguished by the sign of i->last_offset. Checks for "should we extend the last buffer or should we start a new one?" become easier to follow that way. Note that most of the operations can only be done in a sane state - i.e. when the pipe has nothing past the current position of iterator. About the only thing that could be done outside of that state is iov_iter_advance(), which transitions to the sane state by truncating the pipe. There are only two cases where we leave the sane state: 1) iov_iter_get_pages()/iov_iter_get_pages_alloc(). Will be dealt with later, when we make get_pages advancing - the callers are actually happier that way. 2) iov_iter copied, then something is put into the copy. Since they share the underlying pipe, the original gets behind. When we decide that we are done with the copy (original is not usable until then) we advance the original. direct_io used to be done that way; nowadays it operates on the original and we do iov_iter_revert() to discard the excessive data. At the moment there's nothing in the kernel that could do that to ITER_PIPE iterators, so this reason for insane state is theoretical right now.

Use that instead of push_pipe() in copy-to-pipe primitives; they get simpler that way. Handling of short copy (in "mc" one) is done simply by iov_iter_revert() - iov_iter is in consistent state after that one, so we can use that.

47b7fca Al Viro 13 June 2022, 18:30:15 UTC ITER_PIPE: helpers for adding pipe buffers There are only two kinds of pipe_buffer in the area used by ITER_PIPE. 1) anonymous - copy_to_iter() et.al. end up creating those and copying data there. They have zero ->offset, and their ->ops points to default_pipe_page_ops. 2) zero-copy ones - those come from copy_page_to_iter(), and page comes from caller. ->offset is also caller-supplied - it might be non-zero. ->ops points to page_cache_pipe_buf_ops. Move creation and insertion of those into helpers - push_anon(pipe, size) and push_page(pipe, page, offset, size) resp., separating them from the "could we avoid creating a new buffer by merging with the current head?" logics.

2dcedb2 Al Viro 14 June 2022, 14:24:37 UTC ITER_PIPE: helper for getting pipe buffer by index pipe_buffer instances of a pipe are organized as a ring buffer, with power-of-2 size. Indices are kept *not* reduced modulo ring size, so the buffer refered to by index N is pipe->bufs[N & (pipe->ring_size - 1)]. Ring size can change over the lifetime of a pipe, but not while the pipe is locked. So for any iov_iter primitives it's a constant. Original conversion of pipes to this layout went overboard trying to microoptimize that - calculating pipe->ring_size - 1, storing it in a local variable and using through the function. In some cases it might be warranted, but most of the times it only obfuscates what's going on in there. Introduce a helper (pipe_buf(pipe, N)) that would encapsulate that and use it in the obvious cases. More will follow...

It adds support for PRU cores found on the TI K3 AM62x SoCs. It moves the recovery work after a firmware crash to an unbound workqueue, to allow recovery to happen in parallel. A new DMA API is introduced to release dma_mem for a device. It adds support a panic handler for the Qualcomm modem remoteproc, with the goal of having caches flushed in memory dumps for post-mortem debugging and it introduces a mechanism to wait for the modem firmware on SM8450 to decrypt part of its memory for post-mortem debugging. Qualcomm sysmon is restricted to only inform remote processors about peers that are actually running, to avoid a race where Linux tries to notify a recovering remote processor about its peers new state. A mechanism for waiting for the sysmon connection to be established is also introduced, to avoid out-of-sync updates for rapidly restarting remote processors. A number of Devicetree binding cleanups and conversions to YAML are introduced, to facilitate Devicetree validation. Lastly it introduces a number of smaller fixes and cleanups in the core and a few different drivers" * tag 'rproc-v5.20' of git://git.kernel.org/pub/scm/linux/kernel/git/remoteproc/linux: (42 commits) remoteproc: qcom_q6v5_pas: Do not fail if regulators are not found drivers/remoteproc: fix repeated words in comments remoteproc: Directly use ida_alloc()/free() remoteproc: Use unbounded workqueue for recovery work remoteproc: using pm_runtime_resume_and_get instead of pm_runtime_get_sync remoteproc: qcom_q6v5_pas: Deal silently with optional px and cx regulators remoteproc: sysmon: Send sysmon state only for running rprocs remoteproc: sysmon: Wait for SSCTL service to come up remoteproc: qcom: q6v5: Set q6 state to offline on receiving wdog irq remoteproc: qcom: pas: Check if coredump is enabled remoteproc: qcom: pas: Mark devices as wakeup capable remoteproc: qcom: pas: Mark va as io memory remoteproc: qcom: pas: Add decrypt shutdown support for modem remoteproc: qcom: q6v5-mss: add powerdomains to MSM8996 config remoteproc: qcom_q6v5: Introduce panic handler for MSS remoteproc: qcom_q6v5_mss: Update MBA log info remoteproc: qcom: correct kerneldoc remoteproc: qcom_q6v5_mss: map/unmap metadata region before/after use remoteproc: qcom: using pm_runtime_resume_and_get to simplify the code remoteproc: mediatek: Support MT8188 SCP ... 08 August 2022, 22:16:29 UTC

This becomes much easier to do and review now due to the code split to its own directory from effort on the last kernel release. I expect to see more of this with time and as we expand on test coverage in the future. The cleanups and fixes come from usual suspects such as Christophe Leroy and Aaron Tomlin but there are also some other contributors. One particular minor fix worth mentioning is from Helge Deller, where he spotted a *forever* incorrect natural alignment on both ELF section header tables: * .altinstructions * __bug_table sections A lot of back and forth went on in trying to determine the ill effects of this misalignment being present for years and it has been determined there should be no real ill effects unless you have a buggy exception handler. Helge actually hit one of these buggy exception handlers on parisc which is how he ended up spotting this issue. When implemented correctly these paths with incorrect misalignment would just mean a performance penalty, but given that we are dealing with alternatives on modules and with the __bug_table (where info regardign BUG()/WARN() file/line information associated with it is stored) this really shouldn't be a big deal. The only other change with mentioning is the kmap() with kmap_local_page() and my only concern with that was on what is done after preemption, but the virtual addresses are restored after preemption. This is only used on module decompression.

e2ebff9 David Howells 08 August 2022, 08:52:35 UTC vfs: Check the truncate maximum size in inode_newsize_ok() If something manages to set the maximum file size to MAX_OFFSET+1, this can cause the xfs and ext4 filesystems at least to become corrupt. Ordinarily, the kernel protects against userspace trying this by checking the value early in the truncate() and ftruncate() system calls calls - but there are at least two places that this check is bypassed: (1) Cachefiles will round up the EOF of the backing file to DIO block size so as to allow DIO on the final block - but this might push the offset negative. It then calls notify_change(), but this inadvertently bypasses the checking. This can be triggered if someone puts an 8EiB-1 file on a server for someone else to try and access by, say, nfs. (2) ksmbd doesn't check the value it is given in set_end_of_file_info() and then calls vfs_truncate() directly - which also bypasses the check. In both cases, it is potentially possible for a network filesystem to cause a disk filesystem to be corrupted: cachefiles in the client's cache filesystem; ksmbd in the server's filesystem. nfsd is okay as it checks the value, but we can then remove this check too. Fix this by adding a check to inode_newsize_ok(), as called from setattr_prepare(), thereby catching the issue as filesystems set up to perform the truncate with minimal opportunity for bypassing the new check.

af3e957 Linus Torvalds 06 August 2022, 20:24:56 UTC Revert "iommu/dma: Add config for PCI SAC address trick" This reverts commit 4bf7fda4dce22214c70c49960b1b6438e6260b67. It turns out that it was hopelessly naive to think that this would work, considering that we've always done this. The first machine I actually tested this on broke at bootup, getting to Reached target cryptsetup.target - Local Encrypted Volumes. and then hanging. It's unclear what actually fails, since there's a lot else going on around that time (eg amdgpu probing also happens around that same time, but it could be some other random init thing that didn't complete earlier and just caused the boot to hang at that point). The expectations that we should default to some unsafe and untested mode seems entirely unfounded, and the belief that this wouldn't affect modern systems is clearly entirely false. The machine in question is about two years old, so it's not exactly shiny, but it's also not some dusty old museum piece PDP-11 in a closet.

This feature gives users the option to improve IO latency by using a tasklet to verify, using hashes in bufio's cache, rather than wait to schedule a work item via workqueue. But if there is a bufio cache miss, or an error, then the tasklet will fallback to using workqueue. - Incremental changes to both dm-bufio and the DM verity target to use jump_label to minimize cost of branching associated with the niche "try_verify_in_tasklet" feature. DM-bufio in particular is used by quite a few other DM targets so it doesn't make sense to incur additional bufio cost in those targets purely for the benefit of this niche verity feature if the feature isn't ever used. - Optimize verity_verify_io, which is used by both workqueue and tasklet based verification, if FEC is not configured or tasklet based verification isn't used. - Remove DM verity target's verify_wq's use of the WQ_CPU_INTENSIVE flag since it uses WQ_UNBOUND. Also, use the WQ_HIGHPRI flag if "try_verify_in_tasklet" is specified. * tag 'for-6.0/dm-changes-2' of git://git.kernel.org/pub/scm/linux/kernel/git/device-mapper/linux-dm: dm verity: have verify_wq use WQ_HIGHPRI if "try_verify_in_tasklet" dm verity: remove WQ_CPU_INTENSIVE flag since using WQ_UNBOUND dm verity: only copy bvec_iter in verity_verify_io if in_tasklet dm verity: optimize verity_verify_io if FEC not configured dm verity: conditionally enable branching for "try_verify_in_tasklet" dm bufio: conditionally enable branching for DM_BUFIO_CLIENT_NO_SLEEP dm verity: allow optional args to alter primary args handling dm verity: Add optional "try_verify_in_tasklet" feature dm bufio: Add DM_BUFIO_CLIENT_NO_SLEEP flag dm bufio: Add flags argument to dm_bufio_client_create 06 August 2022, 18:09:55 UTC

This introduced vmem_mutex locking from vmem_map_4k_page() function called from smp_reinit_ipl_cpu() with interrupts disabled. While it is a pre-SMP early initcall no other CPUs running in parallel nor other code taking vmem_mutex on this boot stage - it still needs to be fixed.
