[PATCH v3 1/2] accel/rocket: Fix error path handling in rocket_job_run()

by ZhaoJinming

In rocket_job_run(), after taking an extra fence reference for job->done_fence via dma_fence_get(), the error paths have three bugs: - The dma_fence reference held by job->done_fence is never released, causing a reference leak. - pm_runtime_get_sync() increments the usage counter even on failure, but the error path does not decrement it, leaking the runtime PM reference and preventing the NPU from suspending. - A valid but unsignaled fence is returned to the DRM scheduler, which triggers WARN("Fence ... released with pending signals!") when the scheduler drops its reference. Fix by replacing pm_runtime_get_sync() with pm_runtime_resume_and_get() which auto-balances the usage counter on failure, releasing both fence references on error, and returning ERR_PTR(ret) instead of the unsignaled fence.

[PATCH v3 0/2] libfs: set SB_I_NOEXEC and SB_I_NODEV in init_pseudo()

by John Hubbard

This began as a one-line dma-buf fix for a path_noexec() warning added by commit 1e7ab6f67824 ("anon_inode: rework assertions"). Christoph pointed out that the fix belongs higher up: a pseudo filesystem has no reason not to set SB_I_NOEXEC by default. This series does that. * Patch 1 sets both flags in init_pseudo(), so every pseudo filesystem gets them. This is the only patch that changes a flag, and the only one with Fixes:/Cc: stable. * Patch 2 drops the assignments that are now redundant in the callers that set them by hand. Most callers already set one or both flags. I audited every init_pseudo() caller. Here is what patch 1 actually changes for each. The only visible effect is on dma-buf, where SB_I_NOEXEC silences the warning. SB_I_NODEV is never consulted on these SB_NOUSER mounts, and none of the callers that gain SB_I_NOEXEC are executed from. caller had patch 1 adds --------------------------- -------- -------------- fs/anon_inodes.c both nothing new mm/secretmem.c both nothing new virt/kvm/guest_memfd.c both nothing new fs/nsfs.c both nothing new fs/pidfs.c both nothing new fs/aio.c NOEXEC NODEV drivers/dma-buf/dma-buf.c neither NOEXEC + NODEV net/socket.c neither NOEXEC + NODEV fs/pipe.c neither NOEXEC + NODEV kernel/resource.c neither NOEXEC + NODEV fs/erofs/super.c neither NOEXEC + NODEV fs/btrfs/tests/... neither NOEXEC + NODEV drivers/vfio/vfio_main.c neither NOEXEC + NODEV drivers/gpu/drm/drm_drv.c neither NOEXEC + NODEV drivers/dax/super.c neither NOEXEC + NODEV block/bdev.c neither NOEXEC + NODEV John Hubbard (2): libfs: set SB_I_NOEXEC and SB_I_NODEV by default in init_pseudo() libfs: drop redundant SB_I_NOEXEC/SB_I_NODEV in init_pseudo() callers fs/aio.c | 1 - fs/anon_inodes.c | 2 -- fs/libfs.c | 1 + fs/nsfs.c | 1 - fs/pidfs.c | 2 -- mm/secretmem.c | 2 -- virt/kvm/guest_memfd.c | 2 -- 7 files changed, 1 insertion(+), 10 deletions(-) base-commit: ba3e43a9e601636f5edb54e259a74f96ca3b8fd8 -- 2.54.0

Unlocking the Melody: A Guide to Heardle

by many.unicorn.syms＠hidingmail.net

Ever found yourself humming along to a tune, only to realize you can’t quite place the artist or title? If so, you’re in for a treat with Heardle. This delightful online game offers a daily dose of musical trivia, challenging your ear and memory in a surprisingly addictive way. Whether you're a seasoned music aficionado or just looking for a fun brain-teaser, Heardle provides an engaging experience. https://heardlefree.com/ What is Heardle? At its core, Heardle is a daily musical guessing game. Each day, a new song is presented, and your task is to identify it based on short audio snippets. The beauty of Heardle lies in its progressive difficulty. You start with just a second of the intro, and if you’re stumped, you can get more time, up to a maximum of 16 seconds. It's a fantastic way to discover new music or reconnect with old favorites. You can experience the game and try your hand at guessing the daily song by visiting Heardle. Gameplay: Your Daily Musical Challenge Playing Heardle is straightforward and intuitive. When you first open the game, you'll see a simple interface with a play button and a search bar. Listen to the Snippet: Click the play button to hear the initial one-second snippet of the song. Make Your Guess (or Skip): Based on this tiny fragment, you can either type your guess into the search bar. As you type, the game will suggest potential song titles and artists. If you have no idea, or want more time, you can click "Skip" to hear a longer segment. Progressive Reveals: Each time you skip, the audio snippet gets slightly longer, giving you more musical clues. You have a total of six attempts. The Reveal: If you guess correctly, or if you exhaust all your attempts, the song's title and artist are revealed. You'll also see your score (how many attempts it took you) and have the option to share your result. Tips for Mastering Heardle While luck plays a small part, there are strategies to improve your Heardle success rate: Focus on Intros: Many songs have very distinctive introductions. Pay close attention to unique instrumentals, vocal hooks, or production styles in the initial seconds. Genre Awareness: If you have a general idea of the era or genre, it can significantly narrow down your search. Sometimes just knowing it's a 90s pop song or a classic rock anthem is enough to trigger a memory. Don't Be Afraid to Skip: There's no penalty for skipping! If the first second doesn't ring a bell, don't waste time pondering. Get those extra seconds of audio. Hum It Out: Sometimes, humming the tune in your head can help you connect it to lyrics or a title you know. Listen Actively: Instead of just hearing, actively listen for specific instruments, vocal inflections, or rhythmic patterns. Explore Past Heardles: While not directly helping with the current day's song, revisiting past Heardle puzzles can help you train your ear and recognize common song structures. You can often find archives of past games on sites like Heardle. Conclusion Heardle offers a delightful and accessible way to engage with music. It's a perfect brief escape for your coffee break, a fun challenge to share with friends, or simply a way to test your musical knowledge. Give it a try, and you might just surprise yourself with how many melodies you recognize – and perhaps discover a new favorite along the way!

Embrace the Chaos: A Beginner's Guide to the Joy of Basket Random

by unable.rhinoceros.micz＠hidingmail.net

If you are tired of ultra-realistic sports simulators that require complex button combinations and intense strategic planning, it is time to embrace the chaos. Enter the world of physics-based ragdoll games, where the only rule is that there are no rules. At the absolute peak of this hilariously unpredictable genre is Basket Random, a two-button browser game that turns the structured sport of basketball into a chaotic, laughter-inducing spectacle. https://basketrandomgame.com/ Whether you want to kill a few minutes during a study break or challenge a friend to a local duel, here is your ultimate guide to experiencing this delightfully absurd game. What is Basket Random? At its core, the game is a 2v2 basketball match, but with a major twist: your players move like floppy, inflatable tube men. Developed with bouncy ragdoll physics, every round presents a completely randomized setup. One round you might be playing with giant heads on a snowy court with a heavy bowling ball; the next, you are on a sunny beach holding a tiny tennis ball with shortened arms. The objective is simple: be the first to score 5 points. However, achieving that objective is a beautifully chaotic journey of trial, error, and luck. How to Play: One-Button Mastery The beauty of the game lies in its minimalist control scheme. You do not need to worry about passing, sprinting, or shooting buttons. You only need one key: Player 1 (or Single Player): Press the W key (or Up Arrow). Player 2: Press the Up Arrow key. When you tap the key, both of your players will jump and tilt in the direction of the ball. If you hold the key, they will swing their arms and legs wildly. Releasing the key at the right moment allows your player to throw the ball toward the hoop. It sounds simple, but because the physics change with every single point scored, you must constantly adapt your timing to the new weight of the ball, the bounce of the court, and the length of your players' limbs. Tips to Dominate the Chaotic Court While the game relies heavily on accidental moments of brilliance, you can actually develop a loose strategy to win more matches: Master the "Spam" vs. "Hold" Balance: Do not just mash the jump button blindly. If the ball is loose, rapid tapping can help you scramble toward it. However, if your player has possession, hold the button to lean backward, then release it at the peak of your jump for a cleaner arc toward the hoop. Play Defense First: Sometimes, the best offense is a solid block. Position your tallest player under the opponent's hoop to swat away their chaotic shots. Use the Environment: Take note of the court changes. On icy courts, your players will slide much further, which can be used to slide-tackle the ball away from opponents. Conclusion Ultimately, the best way to experience Basket Random is with a friend sitting right next to you. The game’s charm lies in its ability to level the playing field; a seasoned gaming pro can easily lose to a beginner who happened to get a lucky bounce off a player's head. It is a game designed not for sweat and competition, but for shared laughter and high-fives. So, open up your browser, grab a friend, and prepare for some of the most hilarious basketball matches you will ever play.

[PATCH] iommufd: take dma_resv lock before dma_buf_unpin() in release path

dma_buf_unpin() requires the caller to hold the exporter's dma_resv lock: void dma_buf_unpin(struct dma_buf_attachment *attach) { ... dma_resv_assert_held(dmabuf->resv); ... } iopt_release_pages() calls dma_buf_unpin() without taking that lock, so every iommufd_ioas_destroy()/iommufd_ioas_unmap() that releases the last reference on a DMABUF-backed iopt_pages triggers a WARN.

[PATCH] accel/rocket: Fix dma_fence reference leak on error paths in rocket_job_run()

by ZhaoJinming

In rocket_job_run(), after creating a fence at line 305 and taking an extra reference for job->done_fence at line 311 via dma_fence_get(), two error paths fail to release that extra reference before returning: - Line 314: When pm_runtime_get_sync() fails, returns fence without putting job->done_fence. - Line 318: When iommu_attach_group() fails, returns fence without putting job->done_fence, and also omits pm_runtime_put() to balance the successful pm_runtime_get_sync() at line 313. The leaked fence reference prevents the fence and its underlying rocket device from being freed while job->done_fence still points to it. Repeated failures will accumulate leaked fences, consuming kernel memory and holding device resources indefinitely. Fix both error paths by calling dma_fence_put(job->done_fence) and setting job->done_fence to NULL before returning. Also add the missing pm_runtime_put() on the iommu_attach_group error path.
