2024-02-15ALSA: usb-audio: More relaxed check of MIDI jack namesTakashi Iwai1-48/+25
The USB audio driver tries to retrieve MIDI jack name strings that can be used for rawmidi substream names and sequencer port names, but its checking is too strict: often the firmware provides the jack info for unexpected directions, and then we miss the info although it's present. In this patch, the code to extract the jack info is changed to allow both in and out directions in a single loop. That is, the former two functions to obtain the descriptor pointers for jack in and out are changed to a single function that returns iJack of the corresponding jack ID, no matter which direction is used. It's a code simplification at the same time as well as the fix.

2024-02-15pppoe: Fix memory leak in pppoe_sendmsg()Gavrilov Ilia1-14/+9
syzbot reports a memory leak in pppoe_sendmsg [1]. The problem is in the pppoe_recvmsg() function that handles errors in the wrong order. For the skb_recv_datagram() function, check the pointer to skb for NULL first, and then check the 'error' variable, because the skb_recv_datagram() function can set 'error' to -EAGAIN in a loop but return a correct pointer to socket buffer after a number of attempts, though 'error' remains set to -EAGAIN. skb_recv_datagram __skb_recv_datagram // Loop. if (err == -EAGAIN) then // go to the next loop iteration __skb_try_recv_datagram // if (skb != NULL) then return 'skb' // else if a signal is received then // return -EAGAIN Found by InfoTeCS on behalf of Linux Verification Center (linuxtesting.org) with Syzkaller.

2024-02-15arm64/sve: Lower the maximum allocation for the SVE ptrace regsetMark Brown2-7/+8
Doug Anderson observed that ChromeOS crashes are being reported which include failing allocations of order 7 during core dumps due to ptrace allocating storage for regsets: chrome: page allocation failure: order:7, mode:0x40dc0(GFP_KERNEL|__GFP_COMP|__GFP_ZERO), nodemask=(null),cpuset=urgent,mems_allowed=0 ... regset_get_alloc+0x1c/0x28 elf_core_dump+0x3d8/0xd8c do_coredump+0xeb8/0x1378 with further investigation showing that this is: [ 66.957385] DOUG: Allocating 279584 bytes which is the maximum size of the SVE regset. As Doug observes it is not entirely surprising that such a large allocation of contiguous memory might fail on a long running system. The SVE regset is currently sized to hold SVE registers with a VQ of SVE_VQ_MAX which is 512, substantially more than the architectural maximum of 16 which we might see even in a system emulating the limits of the architecture. Since we don't expose the size we tell the regset core externally let's define ARCH_SVE_VQ_MAX with the actual architectural maximum and use that for the regset, we'll still overallocate most of the time but much less so which will be helpful even if the core is fixed to not require contiguous allocations. Specify ARCH_SVE_VQ_MAX in terms of the maximum value that can be written into ZCR_ELx.LEN (where this is set in the hardware). For consistency update the maximum SME vector length to be specified in the same style while we are at it. We could also teach the ptrace core about runtime discoverable regset sizes but that would be a more invasive change and this is being observed in practical systems.

2024-02-15net-timestamp: make sk_tskey more predictable in error pathVadim Fedorenko2-10/+16
When SOF_TIMESTAMPING_OPT_ID is used to ambiguate timestamped datagrams, the sk_tskey can become unpredictable in case of any error happened during sendmsg(). Move increment later in the code and make decrement of sk_tskey in error path. This solution is still racy in case of multiple threads doing snedmsg() over the very same socket in parallel, but still makes error path much more predictable.

2024-02-15drm/xe/vm: Avoid reserving zero fencesThomas Hellström1-3/+10
The function xe_vm_prepare_vma was blindly accepting zero as the number of fences and forwarded that to drm_exec_prepare_obj. However, that leads to an out-of-bounds shift in the dma_resv_reserve_fences() and while one could argue that the dma_resv code should be robust against that, avoid attempting to reserve zero fences.

2024-02-14io_uring/net: fix multishot accept overflow handlingJens Axboe1-2/+3
If we hit CQ ring overflow when attempting to post a multishot accept completion, we don't properly save the result or return code. This results in losing the accepted fd value. Instead, we return the result from the poll operation that triggered the accept retry. This is generally POLLIN|POLLPRI|POLLRDNORM|POLLRDBAND which is 0xc3, or 195, which looks like a valid file descriptor, but it really has no connection to that. Handle this like we do for other multishot completions - assign the result, and return IOU_STOP_MULTISHOT to cancel any further completions from this request when overflow is hit. This preserves the result, as we should, and tells the application that the request needs to be re-armed.

While this is expected if --random is passed to the iptables command, it is not expected without passing --random. The expected behavior (and the observed behavior prior to the commit in the "Fixes" tag) is the traffic will be DNAT'd to 192.168.0.10:21000 unless there is a tuple collision with that destination. In that case, we expect the traffic to be instead DNAT'd to 192.168.0.10:21001, so on so forth until the end of the range.

2024-02-14lsm: fix integer overflow in lsm_set_self_attr() syscallJann Horn1-2/+5
security_setselfattr() has an integer overflow bug that leads to out-of-bounds access when userspace provides bogus input: `lctx->ctx_len + sizeof(*lctx)` is checked against `lctx->len` (and, redundantly, also against `size`), but there are no checks on `lctx->ctx_len`. Therefore, userspace can provide an `lsm_ctx` with `->ctx_len` set to a value between `-sizeof(struct lsm_ctx)` and -1, and this bogus `->ctx_len` will then be passed to an LSM module as a buffer length, causing LSM modules to perform out-of-bounds accesses. The following reproducer will demonstrate this under ASAN (if AppArmor is loaded as an LSM): ``` struct lsm_ctx { uint64_t id; uint64_t flags; uint64_t len; uint64_t ctx_len; char ctx[]; }; int main(void) { size_t size = sizeof(struct lsm_ctx); struct lsm_ctx *ctx = malloc(size); ctx->id = 104/*LSM_ID_APPARMOR*/; ctx->flags = 0; ctx->len = size; ctx->ctx_len = -sizeof(struct lsm_ctx); syscall( 460/*__NR_lsm_set_self_attr*/, /*attr=*/ 100/*LSM_ATTR_CURRENT*/, /*ctx=*/ ctx, /*size=*/ size, /*flags=*/ 0 ); } ``` Fixes: a04a1198088a ("LSM: syscalls for current process attributes") Signed-off-by: Jann Horn <[email protected]> Acked-by: Casey Schaufler <[email protected]> [PM: subj tweak, removed ref to ASAN splat that isn't included] Signed-off-by: Paul Moore <[email protected]>
2024-02-14scsi: sd: usb_storage: uas: Access media prior to querying device propertiesMartin K. Petersen4-1/+40
It has been observed that some USB/UAS devices return generic properties hardcoded in firmware for mode pages for a period of time after a device has been discovered. The reported properties are either garbage or they do not accurately reflect the characteristics of the physical storage device attached in the case of a bridge. Prior to commit 1e029397d12f ("scsi: sd: Reorganize DIF/DIX code to avoid calling revalidate twice") we would call revalidate several times during device discovery. As a result, incorrect values would eventually get replaced with ones accurately describing the attached storage. When we did away with the redundant revalidate pass, several cases were reported where devices reported nonsensical values or would end up in write-protected state. An initial attempt at addressing this issue involved introducing a delayed second revalidate invocation. However, this approach still left some devices reporting incorrect characteristics. Tasos Sahanidis debugged the problem further and identified that introducing a READ operation prior to MODE SENSE fixed the problem and that it wasn't a timing issue. Issuing a READ appears to cause the devices to update their state to reflect the actual properties of the storage media. Device properties like vendor, model, and storage capacity appear to be correctly reported from the get-go. It is unclear why these devices defer populating the remaining characteristics. Match the behavior of a well known commercial operating system and trigger a READ operation prior to querying device characteristics to force the device to populate the mode pages. The additional READ is triggered by a flag set in the USB storage and UAS drivers. We avoid issuing the READ for other transport classes since some storage devices identify Linux through our particular discovery command sequence.

2024-02-14tracing: Inform kmemleak of saved_cmdlines allocationSteven Rostedt (Google)1-0/+3
The allocation of the struct saved_cmdlines_buffer structure changed from: s = kmalloc(sizeof(*s), GFP_KERNEL); s->saved_cmdlines = kmalloc_array(TASK_COMM_LEN, val, GFP_KERNEL); to: orig_size = sizeof(*s) + val * TASK_COMM_LEN; order = get_order(orig_size); size = 1 << (order + PAGE_SHIFT); page = alloc_pages(GFP_KERNEL, order); if (!page) return NULL; s = page_address(page); memset(s, 0, sizeof(*s)); s->saved_cmdlines = kmalloc_array(TASK_COMM_LEN, val, GFP_KERNEL); Where that s->saved_cmdlines allocation looks to be a dangling allocation to kmemleak. That's because kmemleak only keeps track of kmalloc() allocations. For allocations that use page_alloc() directly, the kmemleak needs to be explicitly informed about it. Add kmemleak_alloc() and kmemleak_free() around the page allocation so that it doesn't give the following false positive: unreferenced object 0xffff8881010c8000 (size 32760): comm "swapper", pid 0, jiffies 4294667296 hex dump (first 32 bytes): ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ................ ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ff ................ backtrace (crc ae6ec1b9): [<ffffffff86722405>] kmemleak_alloc+0x45/0x80 [<ffffffff8414028d>] __kmalloc_large_node+0x10d/0x190 [<ffffffff84146ab1>] __kmalloc+0x3b1/0x4c0 [<ffffffff83ed7103>] allocate_cmdlines_buffer+0x113/0x230 [<ffffffff88649c34>] tracer_alloc_buffers.isra.0+0x124/0x460 [<ffffffff8864a174>] early_trace_init+0x14/0xa0 [<ffffffff885dd5ae>] start_kernel+0x12e/0x3c0 [<ffffffff885f5758>] x86_64_start_reservations+0x18/0x30 [<ffffffff885f582b>] x86_64_start_kernel+0x7b/0x80 [<ffffffff83a001c3>] secondary_startup_64_no_verify+0x15e/0x16b Link: https://lore.kernel.org/linux-trace-kernel/[email protected]/ Link: https://lore.kernel.org/linux-trace-kernel/[email protected] Cc: Masami Hiramatsu <[email protected]> Cc: Mathieu Desnoyers <[email protected]> Cc: Catalin Marinas <[email protected]> Fixes: 44dc5c41b5b1 ("tracing: Fix wasted memory in saved_cmdlines logic") Reported-by: Kalle Valo <[email protected]> Tested-by: Kalle Valo <[email protected]> Signed-off-by: Steven Rostedt (Google) <[email protected]>
