To fix this issue, briefly drop uring_lock when calling io_run_task_work_sig(), and there are two things to concern: - hold uring_lock in io_ring_ctx_free() around io_sqe_files_unregister() this is for consistency of lock/unlock. - add new fixed rsrc ref node before dropping uring_lock it's not safe to do io_uring_enter-->percpu_ref_get() with a dying one. - check if rsrc_data->refs is dying to avoid parallel io_sqe_files_unregister Reported-by: Abaci <abaci(a)linux.alibaba.com> Fixes: 1ffc54220c44 ("io_uring: fix io_sqe_files_unregister() hangs") Suggested-by: Pavel Begunkov <asml.silence(a)gmail.com> Signed-off-by: Hao Xu <haoxu(a)linux.alibaba.com> [axboe: fixes from Pavel folded in] Signed-off-by: Jens Axboe <axboe(a)kernel.dk> diff --git a/fs/io_uring.c b/fs/io_uring.c index 582306b1dfd1..7956c6751a67 100644 --- a/fs/io_uring.c +++ b/fs/io_uring.c @@ -236,6 +236,7 @@ struct fixed_rsrc_data { struct fixed_rsrc_ref_node *node; struct percpu_ref refs; struct completion done; + bool quiesce; }; struct io_buffer { @@ -7316,38 +7317,57 @@ static void io_sqe_rsrc_set_node(struct io_ring_ctx *ctx, percpu_ref_get(&rsrc_data->refs); } -static int io_rsrc_ref_quiesce(struct fixed_rsrc_data *data, - struct io_ring_ctx *ctx, - struct fixed_rsrc_ref_node *backup_node) +static void io_sqe_rsrc_kill_node(struct io_ring_ctx *ctx, struct fixed_rsrc_data *data) { - struct fixed_rsrc_ref_node *ref_node; - int ret; + struct fixed_rsrc_ref_node *ref_node = NULL; io_rsrc_ref_lock(ctx); ref_node = data->node; io_rsrc_ref_unlock(ctx); if (ref_node) percpu_ref_kill(&ref_node->refs); +} + +static int io_rsrc_ref_quiesce(struct fixed_rsrc_data *data, + struct io_ring_ctx *ctx, + struct fixed_rsrc_ref_node *backup_node) +{ + int ret; - percpu_ref_kill(&data->refs); + if (data->quiesce) + return -ENXIO; - /* wait for all refs nodes to complete */ - flush_delayed_work(&ctx->rsrc_put_work); + data->quiesce = true; do { + io_sqe_rsrc_kill_node(ctx, data); + percpu_ref_kill(&data->refs); + flush_delayed_work(&ctx->rsrc_put_work); + ret = wait_for_completion_interruptible(&data->done); if (!ret) break; + + percpu_ref_resurrect(&data->refs); + io_sqe_rsrc_set_node(ctx, data, backup_node); + backup_node = NULL; + reinit_completion(&data->done); + mutex_unlock(&ctx->uring_lock); ret = io_run_task_work_sig(); - if (ret < 0) { - percpu_ref_resurrect(&data->refs); - reinit_completion(&data->done); - io_sqe_rsrc_set_node(ctx, data, backup_node); - return ret; - } + mutex_lock(&ctx->uring_lock); + + if (ret < 0) + break; + backup_node = alloc_fixed_rsrc_ref_node(ctx); + ret = -ENOMEM; + if (!backup_node) + break; + init_fixed_file_ref_node(ctx, backup_node); } while (1); + data->quiesce = false; - destroy_fixed_rsrc_ref_node(backup_node); - return 0; + if (backup_node) + destroy_fixed_rsrc_ref_node(backup_node); + return ret; } static struct fixed_rsrc_data *alloc_fixed_rsrc_data(struct io_ring_ctx *ctx) @@ -7382,7 +7402,12 @@ static int io_sqe_files_unregister(struct io_ring_ctx *ctx) unsigned nr_tables, i; int ret; - if (!data) + /* + * percpu_ref_is_dying() is to stop parallel files unregister + * Since we possibly drop uring lock later in this function to + * run task work. + */ + if (!data || percpu_ref_is_dying(&data->refs)) return -ENXIO; backup_node = alloc_fixed_rsrc_ref_node(ctx); if (!backup_node) @@ -8731,7 +8756,9 @@ static void io_ring_ctx_free(struct io_ring_ctx *ctx) css_put(ctx->sqo_blkcg_css); #endif + mutex_lock(&ctx->uring_lock); io_sqe_files_unregister(ctx); + mutex_unlock(&ctx->uring_lock); io_eventfd_unregister(ctx); io_destroy_buffers(ctx); idr_destroy(&ctx->personality_idr);

[PATCH] crypto: mips/poly1305 - enable for all MIPS processors

by Maciej W. Rozycki

The MIPS Poly1305 implementation is generic MIPS code written such as to support down to the original MIPS I and MIPS III ISA for the 32-bit and 64-bit variant respectively. Lift the current limitation then to enable code for MIPSr1 ISA or newer processors only and have it available for all MIPS processors. Signed-off-by: Maciej W. Rozycki <macro(a)orcam.me.uk> Fixes: a11d055e7a64 ("crypto: mips/poly1305 - incorporate OpenSSL/CRYPTOGAMS optimized implementation") Cc: stable(a)vger.kernel.org # v5.5+ --- On Wed, 3 Mar 2021, Jason A.

The performance boost on Octeon is significant for WireGuard users. But that's the wrong fix for that purpose. I've skimmed over that module and there's nothing MIPS64-specific there. In fact it's plain generic MIPS assembly, with some R2 optimisations enabled where applicable but not necessary (and then R6 tweaks, but that's irrelevant here). As a matter of interest I have just built it successfully for a MIPS I DECstation configuration: $ file arch/mips/crypto/poly1305-mips.ko arch/mips/crypto/poly1305-mips.ko: ELF 32-bit LSB relocatable, MIPS, MIPS-I version 1 (SYSV), BuildID[sha1]=d36384d94f60ba7deff638ca8a24500120b45b56, not stripped $ Patch included, please apply.
