2024-08-24pinctrl: rockchip: correct RK3328 iomux width flag for GPIO2-B pinsHuang-Huang Bao
The base iomux offsets for each GPIO pin line are accumulatively calculated based off iomux width flag in rockchip_pinctrl_get_soc_data. If the iomux width flag is one of IOMUX_WIDTH_4BIT, IOMUX_WIDTH_3BIT or IOMUX_WIDTH_2BIT, the base offset for next pin line would increase by 8 bytes, otherwise it would increase by 4 bytes. Despite most of GPIO2-B iomux have 2-bit data width, which can be fit into 4 bytes space with write mask, it actually take 8 bytes width for whole GPIO2-B line. Commit e8448a6c817c ("pinctrl: rockchip: fix pinmux bits for RK3328 GPIO2-B pins") wrongly set iomux width flag to 0, causing all base iomux offset for line after GPIO2-B to be calculated wrong. Fix the iomux width flag to IOMUX_WIDTH_2BIT so the offset after GPIO2-B is correctly increased by 8, matching the actual width of GPIO2-B iomux.

2024-08-24netfs: Fix interaction of streaming writes with zero-point trackerDavid Howells
When a folio that is marked for streaming write (dirty, but not uptodate, with partial content specified in the private data) is written back, the folio is effectively switched to the blank state upon completion of the write. This means that if we want to read it in future, we need to reread the whole folio. However, if the folio is above the zero_point position, when it is read back, it will just be cleared and the read skipped, leading to apparent local corruption. Fix this by increasing the zero_point to the end of the dirty data in the folio when clearing the folio state after writeback. This is analogous to the folio having ->release_folio() called upon it. This was causing the config.log generated by configuring a cpython tree on a cifs share to get corrupted because the scripts involved were appending text to the file in small pieces.

2024-08-24netfs: Fix trimming of streaming-write folios in netfs_inval_folio()David Howells
When netfslib writes to a folio that it doesn't have data for, but that data exists on the server, it will make a 'streaming write' whereby it stores data in a folio that is marked dirty, but not uptodate. When it does this, it attaches a record to folio->private to track the dirty region. When truncate() or fallocate() wants to invalidate part of such a folio, it will call into ->invalidate_folio(), specifying the part of the folio that is to be invalidated. netfs_invalidate_folio(), on behalf of the filesystem, must then determine how to trim the streaming write record. In a couple of cases, however, it does this incorrectly (the reduce-length and move-start cases are switched over and don't, in any case, calculate the value correctly). Fix this by making the logic tree more obvious and fixing the cases.

2024-08-24netfs: Fix netfs_release_folio() to say no if folio dirtyDavid Howells
Fix netfs_release_folio() to say no (ie. return false) if the folio is dirty (analogous with iomap's behaviour). Without this, it will say yes to the release of a dirty page by split_huge_page_to_list_to_order(), which will result in the loss of untruncated data in the folio. Without this, the generic/075 and generic/112 xfstests (both fsx-based tests) fail with minimum folio size patches applied[1].

2024-08-24afs: Fix post-setattr file edit to do truncation correctlyDavid Howells
At the end of an kAFS RPC operation, there is an "edit" phase (originally intended for post-directory modification ops to edit the local image) that the setattr VFS op uses to fix up the pagecache if the RPC that requested truncation of a file was successful. afs_setattr_edit_file() calls truncate_setsize() which sets i_size, expands the pagecache if needed and truncates the pagecache. The first two of those, however, are redundant as they've already been done by afs_setattr_success() under the io_lock and the first is also done under the callback lock (cb_lock). Fix afs_setattr_edit_file() to call truncate_pagecache() instead (which is called by truncate_setsize(), thereby skipping the redundant parts.

2024-08-24mm: Fix missing folio invalidation calls during truncationDavid Howells
When AS_RELEASE_ALWAYS is set on a mapping, the ->release_folio() and ->invalidate_folio() calls should be invoked even if PG_private and PG_private_2 aren't set. This is used by netfslib to keep track of the point above which reads can be skipped in favour of just zeroing pagecache locally. There are a couple of places in truncation in which invalidation is only called when folio_has_private() is true. Fix these to check folio_needs_release() instead. Without this, the generic/075 and generic/112 xfstests (both fsx-based tests) fail with minimum folio size patches applied[1].

This happens as part of call tegra210_mvc_reset_vol_settings() in MVC device probe(). The root cause of this problem is, the child MVC device gets probed before the AHUB clock gets enabled. The AHUB clock is enabled in runtime PM resume of parent AHUB device and due to the wrong sequence of pm_runtime_enable() in AHUB driver, runtime PM resume doesn't happen for AHUB device when MVC makes register access. Fix this by calling pm_runtime_enable() for parent AHUB device before of_platform_populate() in AHUB driver. This ensures that clock becomes available when MVC makes register access.

The max count of lowerdir is OVL_MAX_STACK[500], which is broken by commit 37f32f526438("ovl: fix memory leak in ovl_parse_param()") for parameter Opt_lowerdir. Since commit 819829f0319a("ovl: refactor layer parsing helpers") and commit 24e16e385f22("ovl: add support for appending lowerdirs one by one") added check ovl_mount_dir_check() in function ovl_parse_param_lowerdir(), the 'ctx->nr' should be smaller than OVL_MAX_STACK, after commit 37f32f526438("ovl: fix memory leak in ovl_parse_param()") is applied, the 'ctx->nr' is updated before the check ovl_mount_dir_check(), which leads the max count of lowerdir to become 499 for parameter Opt_lowerdir.

2024-08-23nfsd: prevent panic for nfsv4.0 closed files in nfs4_show_openOlga Kornievskaia
Prior to commit 3f29cc82a84c ("nfsd: split sc_status out of sc_type") states_show() relied on sc_type field to be of valid type before calling into a subfunction to show content of a particular stateid. From that commit, we split the validity of the stateid into sc_status and no longer changed sc_type to 0 while unhashing the stateid. This resulted in kernel oopsing for nfsv4.0 opens that stay around and in nfs4_show_open() would derefence sc_file which was NULL. Instead, for closed open stateids forgo displaying information that relies of having a valid sc_file. To reproduce: mount the server with 4.0, read and close a file and then on the server cat /proc/fs/nfsd/clients/2/states [ 513.590804] Call trace: [ 513.590925] _raw_spin_lock+0xcc/0x160 [ 513.591119] nfs4_show_open+0x78/0x2c0 [nfsd] [ 513.591412] states_show+0x44c/0x488 [nfsd] [ 513.591681] seq_read_iter+0x5d8/0x760 [ 513.591896] seq_read+0x188/0x208 [ 513.592075] vfs_read+0x148/0x470 [ 513.592241] ksys_read+0xcc/0x178 Fixes: 3f29cc82a84c ("nfsd: split sc_status out of sc_type") Signed-off-by: Olga Kornievskaia <okorniev@redhat.com> Reviewed-by: Jeff Layton <jlayton@kernel.org> Signed-off-by: Chuck Lever <chuck.lever@oracle.com>

2024-08-23pinctrl: mediatek: common-v2: Fix broken bias-disable for PULL_PU_PD_RSEL_TYPENícolas F. R. A. Prado
Despite its name, commit fed74d75277d ("pinctrl: mediatek: common-v2: Fix bias-disable for PULL_PU_PD_RSEL_TYPE") actually broke bias-disable for PULL_PU_PD_RSEL_TYPE. mtk_pinconf_bias_set_combo() tries every bias method supported by the pin until one succeeds. For PULL_PU_PD_RSEL_TYPE pins, before the breaking commit, mtk_pinconf_bias_set_rsel() would be called first to try and set the RSEL value (as well as PU and PD), and if that failed, the only other valid option was that bias-disable was specified, which would then be handled by calling mtk_pinconf_bias_set_pu_pd() and disabling both PU and PD. The breaking commit misunderstood this logic and added an early "return 0" in mtk_pinconf_bias_set_rsel(). The result was that in the bias-disable case, the bias was left unchanged, since by returning success, mtk_pinconf_bias_set_combo() no longer tried calling mtk_pinconf_bias_set_pu_pd() to disable the bias. Since the logic for configuring bias-disable on PULL_PU_PD_RSEL_TYPE pins required mtk_pinconf_bias_set_rsel() to fail first, in that case, an error was printed to the log, eg: mt8195-pinctrl 10005000.pinctrl: Not support rsel value 0 Ohm for pin = 29 (GPIO29) This is what the breaking commit actually got rid of, and likely part of the reason why that commit was thought to be fixing functionality, while in reality it was breaking it. Instead of simply reverting that commit, restore the functionality but in a way that avoids the error from being printed and makes the code less confusing: * Return 0 explicitly if a bias method was successful * Introduce an extra function mtk_pinconf_bias_set_pu_pd_rsel() that calls both mtk_pinconf_bias_set_rsel() (only if needed) and mtk_pinconf_bias_set_pu_pd() * And analogously for the corresponding getters Fixes: fed74d75277d ("pinctrl: mediatek: common-v2: Fix bias-disable for PULL_PU_PD_RSEL_TYPE") Signed-off-by: Nícolas F.

2024-08-23net: mana: Fix race of mana_hwc_post_rx_wqe and new hwc responseHaiyang Zhang
The mana_hwc_rx_event_handler() / mana_hwc_handle_resp() calls complete(&ctx->comp_event) before posting the wqe back. It's possible that other callers, like mana_create_txq(), start the next round of mana_hwc_send_request() before the posting of wqe. And if the HW is fast enough to respond, it can hit no_wqe error on the HW channel, then the response message is lost.

2024-08-23platform/x86/amd/pmc: Fix SMU command submission path on new AMD platformShyam Sundar S K
The commit 426463d94d45 ("platform/x86/amd/pmc: Send OS_HINT command for new AMD platform") was introduced to enable sending mailbox commands to PMFW on newer platforms. However, it was later discovered that the commit did not configure the correct message port ID (i.e., S2D or PMC). Without this configuration, all command submissions to PMFW are treated as invalid, leading to command failures. To address this issue, the CPU ID association for the new platform needs to be added in amd_pmc_get_ip_info(). This ensures that the correct SMU port IDs are selected.

2024-08-23irqchip/irq-msi-lib: Check for NULL ops in msi_lib_irq_domain_select()Maxime Chevallier
The irq_domain passed to msi_lib_irq_domain_select() may not have msi_parent_ops set. There is a NULL pointer check for it, but unfortunately there is a dereference of the parent ops pointer before that. Move the NULL pointer test before the first use of that pointer. This was found on a MacchiatoBin (Marvell Armada 8K SoC), which uses the irq-mvebu-sei driver.
