2024-11-19nvme-fabrics: fix kernel crash while shutting down controllerNilay Shroff
The nvme keep-alive operation, which executes at a periodic interval, could potentially sneak in while shutting down a fabric controller. This may lead to a race between the fabric controller admin queue destroy code path (invoked while shutting down controller) and hw/hctx queue dispatcher called from the nvme keep-alive async request queuing operation. This race could lead to the kernel crash shown below: Call Trace: autoremove_wake_function+0x0/0xbc (unreliable) __blk_mq_sched_dispatch_requests+0x114/0x24c blk_mq_sched_dispatch_requests+0x44/0x84 blk_mq_run_hw_queue+0x140/0x220 nvme_keep_alive_work+0xc8/0x19c [nvme_core] process_one_work+0x200/0x4e0 worker_thread+0x340/0x504 kthread+0x138/0x140 start_kernel_thread+0x14/0x18 While shutting down fabric controller, if nvme keep-alive request sneaks in then it would be flushed off. The nvme_keep_alive_end_io function is then invoked to handle the end of the keep-alive operation which decrements the admin->q_usage_counter and assuming this is the last/only request in the admin queue then the admin->q_usage_counter becomes zero. If that happens then blk-mq destroy queue operation (blk_mq_destroy_ queue()) which could be potentially running simultaneously on another cpu (as this is the controller shutdown code path) would forward progress and deletes the admin queue. So, now from this point onward we are not supposed to access the admin queue resources. However the issue here's that the nvme keep-alive thread running hw/hctx queue dispatch operation hasn't yet finished its work and so it could still potentially access the admin queue resource while the admin queue had been already deleted and that causes the above crash. The above kernel crash is regression caused due to changes implemented in commit a54a93d0e359 ("nvme: move stopping keep-alive into nvme_uninit_ctrl()"). Ideally we should stop keep-alive before destroyin g the admin queue and freeing the admin tagset so that it wouldn't sneak in during the shutdown operation. However we removed the keep alive stop operation from the beginning of the controller shutdown code path in commit a54a93d0e359 ("nvme: move stopping keep-alive into nvme_uninit_ctrl()") and added it under nvme_uninit_ctrl() which executes very late in the shutdown code path after the admin queue is destroyed and its tagset is removed. So this change created the possibility of keep-alive sneaking in and interfering with the shutdown operation and causing observed kernel crash. To fix the observed crash, we decided to move nvme_stop_keep_alive() from nvme_uninit_ctrl() to nvme_remove_admin_tag_set(). This change would ensure that we don't forward progress and delete the admin queue until the keep- alive operation is finished (if it's in-flight) or cancelled and that would help contain the race condition explained above and hence avoid the crash. Moving nvme_stop_keep_alive() to nvme_remove_admin_tag_set() instead of adding nvme_stop_keep_alive() to the beginning of the controller shutdown code path in nvme_stop_ctrl(), as was the case earlier before commit a54a93d0e359 ("nvme: move stopping keep-alive into nvme_uninit_ctrl()"), would help save one callsite of nvme_stop_keep_alive().

2024-11-19Revert "nvme: make keep-alive synchronous operation"Nilay Shroff
This reverts commit d06923670b5a5f609603d4a9fee4dec02d38de9c. It was realized that the fix implemented to contain the race condition among the keep alive task and the fabric shutdown code path in the commit d06923670b5ia ("nvme: make keep-alive synchronous operation") is not optimal. The reason being keep-alive runs under the workqueue and making it synchronous would waste a workqueue context. Furthermore, we later found that the above race condition is a regression caused due to the changes implemented in commit a54a93d0e359 ("nvme: move stopping keep-alive into nvme_uninit_ctrl()"). So we decided to revert the commit d06923670b5a ("nvme: make keep-alive synchronous operation") and then fix the regression.

Current loop calls vfs_statfs() while holding the q->limits_lock. If FS takes some locking in vfs_statfs callback, this may lead to ABBA locking bug (at least, FAT fs has this issue actually). So this patch calls vfs_statfs() outside q->limits_locks instead, because looks like no reason to hold q->limits_locks while getting discord configs.

2024-11-19Merge tag 'spi-nor/for-6.13' of ↵Miquel Raynal
git://git.kernel.org/pub/scm/linux/kernel/git/mtd/linux into mtd/next SPI NOR introduces byte swap support for 8D-8D-8D mode and a user for it: macronix. SPI NOR flashes may swap the bytes on a 16-bit boundary when configured in Octal DTR mode. For such cases the byte order is propagated through SPI MEM to the SPI controllers so that the controllers swap the bytes back at runtime. This avoids breaking the boot sequence because of the endianness problems that appear when the bootloaders use 1-1-1 and the kernel uses 8D-8D-8D with byte swap support. Along with the SPI MEM byte swap support we queue a patch for the SPI MXIC controller that swaps the bytes back at runtime. # -----BEGIN PGP SIGNATURE----- # # iQEzBAABCgAdFiEEHUIqys8OyG1eHf7fS1VPR6WNFOkFAmczG/oACgkQS1VPR6WN # FOnTCAf/YjH9AimQAFJLRKoGqsf6boh1JppcRh1YTRS+D6+Ap9+s1gJoZZYs5VWA # vNfBzGqDXknBvpmOgoXnuDu2zFs9FUvdN5Kf7w6LiS5qtz7uOxHdVoDQyDgnN6w5 # 9ts7qF7LViBHg/HgTEzQT2Zj6qmvIwUbccIkmJeehWjEP/urzOML5nPnM9g4HZVB # W8B5KQ4TiOY1GxkXvIP6EQS6mDKznP3yl2Hnsmk0HPpSm6D807O2zvT+z1SCxpjy # C8+mYRKsRxHoFGL6UzWgqREGBn2wzF7Ral1CR9SpSZZLLtr6S0shqRzKiiH8eiZK # 1hFpXzMS3OWi4a/5724AWaqcR0Qgqw== # =jf3Q # -----END PGP SIGNATURE----- # gpg: Signature made Tue 12 Nov 2024 10:12:26 AM CET # gpg: using RSA key 1D422ACACF0EC86D5E1DFEDF4B554F47A58D14E9 # gpg: Good signature from "Tudor Ambarus (4096-bit rsa key) <tudor.ambarus@microchip.com>" [full] # gpg: aka "Tudor Ambarus <tudor.ambarus@gmail.com>" [full] # gpg: tudor.ambarus@microchip.com: Verified 15 signatures in the past 5 years. # Encrypted 0 messages. # gpg: tudor.ambarus@gmail.com: Verified 15 signatures in the past 5 years. # Encrypted 0 messages.

2024-11-18clk: clk-loongson2: Fix potential buffer overflow in flexible-array member ↵Gustavo A. R. Silva
access Flexible-array member `hws` in `struct clk_hw_onecell_data` is annotated with the `counted_by()` attribute. This means that when memory is allocated for this array, the _counter_, which in this case is member `num` in the flexible structure, should be set to the maximum number of elements the flexible array can contain, or fewer. In this case, the total number of elements for the flexible array is determined by variable `clks_num` when allocating heap space via `devm_kzalloc()`, as shown below: 289 struct loongson2_clk_provider *clp; ... 296 for (p = data; p->name; p++) 297 clks_num++; 298 299 clp = devm_kzalloc(dev, struct_size(clp, clk_data.hws, clks_num), 300 GFP_KERNEL); So, `clp->clk_data.num` should be set to `clks_num` or less, and not exceed `clks_num`, as is currently the case. Otherwise, if data is written into `clp->clk_data.hws[clks_num]`, the instrumentation provided by the compiler won't detect the overflow, leading to a memory corruption bug at runtime. Fix this issue by setting `clp->clk_data.num` to `clks_num`. Fixes: 9796ec0bd04b ("clk: clk-loongson2: Refactor driver for adding new platforms") Cc: stable@vger.kernel.org Signed-off-by: Gustavo A.

2024-11-18clk: Fix invalid execution of clk_set_rateChuan Liu
Some clocks have rates that can be changed elsewhere, so add a flag CLK_GET_RATE_NOCACHE(such as scmi_clk) to these clocks to ensure that the real-time rate is obtained. When clk_set_rate is called, it is returned if the request to set rate is consistent with the current rate. Getting the current rate in clk_set_rate returns the rate stored in clk_core. CLK_GET_RATE_NOCACHE does not take effect here.

2024-11-18clk: clk-loongson2: Fix memory corruption bug in struct loongson2_clk_providerGustavo A. R. Silva
Some heap space is allocated for the flexible structure `struct clk_hw_onecell_data` and its flexible-array member `hws` through the composite structure `struct loongson2_clk_provider` in function `loongson2_clk_probe()`, as shown below: 289 struct loongson2_clk_provider *clp; ... 296 for (p = data; p->name; p++) 297 clks_num++; 298 299 clp = devm_kzalloc(dev, struct_size(clp, clk_data.hws, clks_num), 300 GFP_KERNEL); Then some data is written into the flexible array: 350 clp->clk_data.hws[p->id] = hw; This corrupts `clk_lock`, which is the spinlock variable immediately following the `clk_data` member in `struct loongson2_clk_provider`: struct loongson2_clk_provider { void __iomem *base; struct device *dev; struct clk_hw_onecell_data clk_data; spinlock_t clk_lock; /* protect access to DIV registers */ }; The problem is that the flexible structure is currently placed in the middle of `struct loongson2_clk_provider` instead of at the end. Fix this by moving `struct clk_hw_onecell_data clk_data;` to the end of `struct loongson2_clk_provider`. Also, add a code comment to help prevent this from happening again in case new members are added to the structure in the future. This change also fixes the following -Wflex-array-member-not-at-end warning: drivers/clk/clk-loongson2.c:32:36: warning: structure containing a flexible array member is not at the end of another structure [-Wflex-array-member-not-at-end] Fixes: 9796ec0bd04b ("clk: clk-loongson2: Refactor driver for adding new platforms") Cc: stable@vger.kernel.org Signed-off-by: Gustavo A.

2024-11-18wireguard: device: support big tcp GSODaniel Borkmann
Advertise GSO_MAX_SIZE as TSO max size in order support BIG TCP for wireguard. This helps to improve wireguard performance a bit when enabled as it allows wireguard to aggregate larger skbs in wg_packet_consume_data_done() via napi_gro_receive(), but also allows the stack to build larger skbs on xmit where the driver then segments them before encryption inside wg_xmit(). We've seen a 15% improvement in TCP stream performance. Signed-off-by: Daniel Borkmann <daniel@iogearbox.net> Signed-off-by: Jason A.
