[PATCH RFC v2] soc: qcom: pmic_glink: Fix device access from worker during suspend

by Abel Vesa

For historical reasons, the GLINK smem interrupt is registered with IRRQF_NO_SUSPEND flag set, which is the underlying problem here, since the incoming messages can be delivered during late suspend and early resume. In this specific case, the pmic_glink_altmode_worker() currently gets scheduled on the system_wq which can be scheduled to run while devices are still suspended. This proves to be a problem when a Type-C retimer, switch or mux that is controlled over a bus like I2C, because the I2C controller is suspended. This has been proven to be the case on the X Elite boards where such retimers (ParadeTech PS8830) are used in order to handle Type-C orientation and altmode configuration. The following warning is thrown: [ 35.134876] i2c i2c-4: Transfer while suspended [ 35.143865] WARNING: CPU: 0 PID: 99 at drivers/i2c/i2c-core.h:56 __i2c_transfer+0xb4/0x57c [i2c_core] [ 35.352879] Workqueue: events pmic_glink_altmode_worker [pmic_glink_altmode] [ 35.360179] pstate: 61400005 (nZCv daif +PAN -UAO -TCO +DIT -SSBS BTYPE=--) [ 35.455242] Call trace: [ 35.457826] __i2c_transfer+0xb4/0x57c [i2c_core] (P) [ 35.463086] i2c_transfer+0x98/0xf0 [i2c_core] [ 35.467713] i2c_transfer_buffer_flags+0x54/0x88 [i2c_core] [ 35.473502] regmap_i2c_write+0x20/0x48 [regmap_i2c] [ 35.478659] _regmap_raw_write_impl+0x780/0x944 [ 35.483401] _regmap_bus_raw_write+0x60/0x7c [ 35.487848] _regmap_write+0x134/0x184 [ 35.491773] regmap_write+0x54/0x78 [ 35.495418] ps883x_set+0x58/0xec [ps883x] [ 35.499688] ps883x_sw_set+0x60/0x84 [ps883x] [ 35.504223] typec_switch_set+0x48/0x74 [typec] [ 35.508952] pmic_glink_altmode_worker+0x44/0x1fc [pmic_glink_altmode] [ 35.515712] process_scheduled_works+0x1a0/0x2d0 [ 35.520525] worker_thread+0x2a8/0x3c8 [ 35.524449] kthread+0xfc/0x184 [ 35.527749] ret_from_fork+0x10/0x20 The proper solution here should be to not deliver these kind of messages during system suspend at all, or at least make it configurable per glink client. But simply dropping the IRQF_NO_SUSPEND flag entirely will break other clients. The final shape of the rework of the pmic glink driver in order to fulfill both the filtering of the messages that need to be able to wake-up the system and the queueing of these messages until the system has properly resumed is still being discussed and it is planned as a future effort. Meanwhile, the stop-gap fix here is to schedule the pmic glink altmode worker on the system_freezable_wq instead of the system_wq. This will result in the altmode worker not being scheduled to run until the devices are resumed first, which will give the controllers like I2C a chance to resume before the transfer is requested.

[PATCH v1 01/12] mm/gup: reject FOLL_SPLIT_PMD with hugetlb VMAs

We only have two FOLL_SPLIT_PMD users. While uprobe refuses hugetlb early, make_device_exclusive_range() can end up getting called on hugetlb VMAs. Right now, this means that with a PMD-sized hugetlb page, we can end up calling split_huge_pmd(), because pmd_trans_huge() also succeeds with hugetlb PMDs.

[PATCH stable-6.1 1/1] io_uring: fix waiters missing wake ups

by Pavel Begunkov

[ upstream commit 3181e22fb79910c7071e84a43af93ac89e8a7106 ] There are reports of mariadb hangs, which is caused by a missing barrier in the waking code resulting in waiters losing events. The problem was introduced in a backport 3ab9326f93ec4 ("io_uring: wake up optimisations"), and the change restores the barrier present in the original commit 3ab9326f93ec4 ("io_uring: wake up optimisations") Reported by: Xan Charbonnet <xan(a)charbonnet.com> Fixes: 3ab9326f93ec4 ("io_uring: wake up optimisations") Link: https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1093243#99 Signed-off-by: Pavel Begunkov <asml.silence(a)gmail.com> --- io_uring/io_uring.c | 4 +++- 1 file changed, 3 insertions(+), 1 deletion(-) diff --git a/io_uring/io_uring.c b/io_uring/io_uring.c index 9b58ba4616d40..e5a8ee944ef59 100644 --- a/io_uring/io_uring.c +++ b/io_uring/io_uring.c @@ -592,8 +592,10 @@ static inline void __io_cq_unlock_post_flush(struct io_ring_ctx *ctx) io_commit_cqring(ctx); spin_unlock(&ctx->completion_lock); io_commit_cqring_flush(ctx); - if (!(ctx->flags & IORING_SETUP_DEFER_TASKRUN)) + if (!(ctx->flags & IORING_SETUP_DEFER_TASKRUN)) { + smp_mb(); __io_cqring_wake(ctx); + } } void io_cq_unlock_post(struct io_ring_ctx *ctx) -- 2.47.1

Backport smb client fix for special files

by Pali Rohár

Hello, I would like to propose backporting this commit to stable releases: https://git.kernel.org/torvalds/c/3681c74d342db75b0d641ba60de27bf73e16e66b smb: client: handle lack of EA support in smb2_query_path_info() It is fixing support for querying special files (fifo/socket/block/char) over SMB2+ servers which do not support extended attributes and reparse point at the same time on one inode, which applied for older Windows servers (pre-Win10). I think that commit should have line: Fixes: ea41367b2a60 ("smb: client: introduce SMB2_OP_QUERY_WSL_EA") Note that the mention commit depends on: ca4b2c460743 ("fs/smb/client: avoid querying SMB2_OP_QUERY_WSL_EA for SMB3 POSIX") Pali

[PATCH v1 02/12] mm/rmap: reject hugetlb folios in folio_make_device_exclusive()

by David Hildenbrand

Even though FOLL_SPLIT_PMD on hugetlb now always fails with -EOPNOTSUPP, let's add a safety net in case FOLL_SPLIT_PMD usage would ever be reworked. In particular, before commit 9cb28da54643 ("mm/gup: handle hugetlb in the generic follow_page_mask code"), GUP(FOLL_SPLIT_PMD) would just have returned a page. In particular, hugetlb folios that are not PMD-sized would never have been prone to FOLL_SPLIT_PMD. hugetlb folios can be anonymous, and page_make_device_exclusive_one() is not really prepared for handling them at all. So let's spell that out.
