[PATCH] block: mark GFP_NOIO around sysfs ->store()

by Ming Lei

sysfs ->store is called with queue freezed, meantime we have several ->store() callbacks(update_nr_requests, wbt, scheduler) to allocate memory with GFP_KERNEL which may run into direct reclaim code path, then potential deadlock can be caused.

[PATCH v2] Bluetooth: qca: Support downloading board ID specific NVM for WCN6855

by Zijun Hu

For WCN6855, board ID specific NVM needs to be downloaded once board ID is available, but the default NVM is always downloaded currently, and the wrong NVM causes poor RF performance which effects user experience.

Make sence, it seems we only need to save the rest data beside dwBlockLength for next unwrap if a hack is acceptable, otherwise I may need to check if a custom host driver for Windows10 user feasible.

Yes, I am using USB2.0 connection to better capture the crime scene. Normally the OUT transfer on USB3.0 SuperSpeed connection comes with a bunch of 1024B Data Pakcet along with a Short Packet less than 1024B in the end from the Lecroy trace. It's also reproducible on USB3.0 SuperSpeed connection using dwc3 controller, but it will cost more time and make it difficult to capture the online data (limited tracer HW buffer), I can try using software tracing or custom logs later: [ 5] 26.00-27.00 sec 183 MBytes 1.54 Gbits/sec [ 5] 27.00-28.00 sec 182 MBytes 1.53 Gbits/sec [ 206.123935] configfs.gadget.2: Wrong NDP SIGN [ 206.129785] configfs.gadget.2: Wrong NTH SIGN, skblen 12208 [ 206.136802] HEAD:0000000004f66a88: 80 06 bc f9 c0 a8 24 66 c0 a8 24 65 f7 24 14 51 aa 1a 30 d5 01 f8 01 26 50 10 20 14 27 3d 00 00 [ 5] 28.00-29.00 sec 128 MBytes 1.07 Gbits/sec [ 5] 29.00-30.00 sec 191 MBytes 1.61 Gbits/sec > > Presumably '512' would be '64' with USB1.0/1.1, but I guess finding a > USB1.x port/host to test against is likely to be near impossible... > > I'll try to see if I can find the source of the bug in the Win > driver's sources (though based on it being Win10 only, may need to > search history) > It's great if you can analyze from the host driver. I didn't know if the NCM driver open-sourced on github by M$ is the correspond version. They said that only Win 11 officially support NCM in the issue on github yet they do have a built-in driver in Win10 and 2004 tag there in the repo.

[PATCH v4] [ARM] fix reference leak in locomo_init_one_child()

by Ma Ke

Once device_register() failed, we should call put_device() to decrement reference count for cleanup. Or it could cause memory leak. device_register() includes device_add(). As comment of device_add() says, 'if device_add() succeeds, you should call device_del() when you want to get rid of it. If device_add() has not succeeded, use only put_device() to drop the reference count'. Found by code review.

[PATCH v2 1/7] mm/hugetlb: Fix avoid_reserve to allow taking folio from subpool

by Peter Xu

Since commit 04f2cbe35699 ("hugetlb: guarantee that COW faults for a process that called mmap(MAP_PRIVATE) on hugetlbfs will succeed"), avoid_reserve was introduced for a special case of CoW on hugetlb private mappings, and only if the owner VMA is trying to allocate yet another hugetlb folio that is not reserved within the private vma reserved map. Later on, in commit d85f69b0b533 ("mm/hugetlb: alloc_huge_page handle areas hole punched by fallocate"), alloc_huge_page() enforced to not consume any global reservation as long as avoid_reserve=true. This operation doesn't look correct, because even if it will enforce the allocation to not use global reservation at all, it will still try to take one reservation from the spool (if the subpool existed). Then since the spool reserved pages take from global reservation, it'll also take one reservation globally. Logically it can cause global reservation to go wrong. I wrote a reproducer below, trigger this special path, and every run of such program will cause global reservation count to increment by one, until it hits the number of free pages: #define _GNU_SOURCE /* See feature_test_macros(7) */ #include <stdio.h> #include <fcntl.h> #include <errno.h> #include <unistd.h> #include <stdlib.h> #include <sys/mman.h> #define MSIZE (2UL << 20) int main(int argc, char *argv[]) { const char *path; int *buf; int fd, ret; pid_t child; if (argc < 2) { printf("usage: %s <hugetlb_file>\n", argv[0]); return -1; } path = argv[1]; fd = open(path, O_RDWR | O_CREAT, 0666); if (fd < 0) { perror("open failed"); return -1; } ret = fallocate(fd, 0, 0, MSIZE); if (ret != 0) { perror("fallocate"); return -1; } buf = mmap(NULL, MSIZE, PROT_READ|PROT_WRITE, MAP_PRIVATE, fd, 0); if (buf == MAP_FAILED) { perror("mmap() failed"); return -1; } /* Allocate a page */ *buf = 1; child = fork(); if (child == 0) { /* child doesn't need to do anything */ exit(0); } /* Trigger CoW from owner */ *buf = 2; munmap(buf, MSIZE); close(fd); unlink(path); return 0; } It can only reproduce with a sub-mount when there're reserved pages on the spool, like: # sysctl vm.nr_hugepages=128 # mkdir ./hugetlb-pool # mount -t hugetlbfs -o min_size=8M,pagesize=2M none ./hugetlb-pool Then run the reproducer on the mountpoint: # ./reproducer ./hugetlb-pool/test Fix it by taking the reservation from spool if available. In general, avoid_reserve is IMHO more about "avoid vma resv map", not spool's. I copied stable, however I have no intention for backporting if it's not a clean cherry-pick, because private hugetlb mapping, and then fork() on top is too rare to hit.

[PATCH 1/2] media: streamzap: fix race between device disconnection and urb callback

by Murad Masimov

Syzkaller has reported a general protection fault at function ir_raw_event_store_with_filter(). This crash is caused by a NULL pointer dereference of dev->raw pointer, even though it is checked for NULL in the same function, which means there is a race condition. It occurs due to the incorrect order of actions in the streamzap_disconnect() function: rc_unregister_device() is called before usb_kill_urb(). The dev->raw pointer is freed and set to NULL in rc_unregister_device(), and only after that usb_kill_urb() waits for in-progress requests to finish. If rc_unregister_device() is called while streamzap_callback() handler is not finished, this can lead to accessing freed resources. Thus rc_unregister_device() should be called after usb_kill_urb(). Found by Linux Verification Center (linuxtesting.org) with Syzkaller.

Later, univ8250_console_exit() will trigger the runtime PM usage counter underflow as .dev is already set at that time. Call pm_runtime_get_sync() to balance the RPM usage counter also in serial8250_register_8250_port() before trying to add the port.
