[PATCH net v3] net: nfc: nci: Add parameter validation for packet data

by Deepak Sharma

Syzbot reported an uninit-value bug at nci_init_req for commit 5aca7966d2a7 ("Merge tag 'perf-tools-fixes-for-v6.17-2025-09-16'..). This bug arises due to very limited and poor input validation that was done at nic_valid_size(). This validation only validates the skb->len (directly reflects size provided at the userspace interface) with the length provided in the buffer itself (interpreted as NCI_HEADER). This leads to the processing of memory content at the address assuming the correct layout per what opcode requires there. This leads to the accesses to buffer of `skb_buff->data` which is not assigned anything yet. Following the same silent drop of packets of invalid sizes at `nic_valid_size()`, add validation of the data in the respective handlers and return error values in case of failure. Release the skb if error values are returned from handlers in `nci_nft_packet` and effectively do a silent drop Possible TODO: because we silently drop the packets, the call to `nci_request` will be waiting for completion of request and will face timeouts. These timeouts can get excessively logged in the dmesg. A proper handling of them may require to export `nci_request_cancel` (or propagate error handling from the nft packets handlers).

[PATCH v2 RESEND] sparc: fix error handling in scan_one_device()

by Ma Ke

Once of_device_register() failed, we should call put_device() to decrement reference count for cleanup. Or it could cause memory leak. So fix this by calling put_device(), then the name can be freed in kobject_cleanup(). Calling path: of_device_register() -> of_device_add() -> 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.

[bug-report 6.12.y] Probably a problematic stable backport commit: 7c62c442b6eb ("x86/vmscape: Enumerate VMSCAPE bug")

by Harshit Mogalapalli

Hi stable maintainers, While skimming over stable backports for VMSCAPE commits, I found something unusual. This is regarding the 6.12.y commit: 7c62c442b6eb ("x86/vmscape: Enumerate VMSCAPE bug") commit 7c62c442b6eb95d21bc4c5afc12fee721646ebe2 Author: Pawan Gupta <pawan.kumar.gupta(a)linux.intel.com> Date: Thu Aug 14 10:20:42 2025 -0700 x86/vmscape: Enumerate VMSCAPE bug Commit a508cec6e5215a3fbc7e73ae86a5c5602187934d upstream. The VMSCAPE vulnerability may allow a guest to cause Branch Target Injection (BTI) in userspace hypervisors. Kernels (both host and guest) have existing defenses against direct BTI attacks from guests. There are also inter-process BTI mitigations which prevent processes from attacking each other. However, the threat in this case is to a userspace hypervisor within the same process as the attacker. Userspace hypervisors have access to their own sensitive data like disk encryption keys and also typically have access to all guest data. This means guest userspace may use the hypervisor as a confused deputy to attack sensitive guest kernel data. There are no existing mitigations for these attacks. Introduce X86_BUG_VMSCAPE for this vulnerability and set it on affected Intel and AMD CPUs. Signed-off-by: Pawan Gupta <pawan.kumar.gupta(a)linux.intel.com> Signed-off-by: Dave Hansen <dave.hansen(a)linux.intel.com> Reviewed-by: Borislav Petkov (AMD) <bp(a)alien8.de> Signed-off-by: Borislav Petkov (AMD) <bp(a)alien8.de> Signed-off-by: Greg Kroah-Hartman <gregkh(a)linuxfoundation.org> So the problem in this commit is this part of the backport: in file: arch/x86/kernel/cpu/common.c VULNBL_AMD(0x15, RETBLEED), VULNBL_AMD(0x16, RETBLEED), - VULNBL_AMD(0x17, RETBLEED | SMT_RSB | SRSO), - VULNBL_HYGON(0x18, RETBLEED | SMT_RSB | SRSO), - VULNBL_AMD(0x19, SRSO | TSA), + VULNBL_AMD(0x17, RETBLEED | SMT_RSB | SRSO | VMSCAPE), + VULNBL_HYGON(0x18, RETBLEED | SMT_RSB | SRSO | VMSCAPE), + VULNBL_AMD(0x19, SRSO | TSA | VMSCAPE), + VULNBL_AMD(0x1a, SRSO | VMSCAPE), + {} Notice the part where VULNBL_AMD(0x1a, SRSO | VMSCAPE) is added, 6.12.y doesn't have commit: 877818802c3e ("x86/bugs: Add SRSO_USER_KERNEL_NO support") so I think we shouldn't be adding VULNBL_AMD(0x1a, SRSO | VMSCAPE) directly.

[PATCH] ceph: fix deadlock bugs by making iput() calls asynchronous

by Max Kellermann

The iput() function is a dangerous one - if the reference counter goes to zero, the function may block for a long time due to: - inode_wait_for_writeback() waits until writeback on this inode completes - the filesystem-specific "evict_inode" callback can do similar things; e.g. all netfs-based filesystems will call netfs_wait_for_outstanding_io() which is similar to inode_wait_for_writeback() Therefore, callers must carefully evaluate the context they're in and check whether invoking iput() is a good idea at all. Most of the time, this is not a problem because the dcache holds references to all inodes, and the dcache is usually the one to release the last reference. But this assumption is fragile. For example, under (memcg) memory pressure, the dcache shrinker is more likely to release inode references, moving the inode eviction to contexts where that was extremely unlikely to occur. Our production servers "found" at least two deadlock bugs in the Ceph filesystem that were caused by this iput() behavior: 1. Writeback may lead to iput() calls in Ceph (e.g. from ceph_put_wrbuffer_cap_refs()) which deadlocks in inode_wait_for_writeback(). Waiting for writeback completion from within writeback will obviously never be able to make any progress. This leads to blocked kworkers like this: INFO: task kworker/u777:6:1270802 blocked for more than 122 seconds. Not tainted 6.16.7-i1-es #773 task:kworker/u777:6 state:D stack:0 pid:1270802 tgid:1270802 ppid:2 task_flags:0x4208060 flags:0x00004000 Workqueue: writeback wb_workfn (flush-ceph-3) Call Trace: <TASK> __schedule+0x4ea/0x17d0 schedule+0x1c/0xc0 inode_wait_for_writeback+0x71/0xb0 evict+0xcf/0x200 ceph_put_wrbuffer_cap_refs+0xdd/0x220 ceph_invalidate_folio+0x97/0xc0 ceph_writepages_start+0x127b/0x14d0 do_writepages+0xba/0x150 __writeback_single_inode+0x34/0x290 writeback_sb_inodes+0x203/0x470 __writeback_inodes_wb+0x4c/0xe0 wb_writeback+0x189/0x2b0 wb_workfn+0x30b/0x3d0 process_one_work+0x143/0x2b0 worker_thread+0x30a/0x450 2. In the Ceph messenger thread (net/ceph/messenger*.c), any iput() call may invoke ceph_evict_inode() which will deadlock in netfs_wait_for_outstanding_io(); since this blocks the messenger thread, completions from the Ceph servers will not ever be received and handled. It looks like these deadlock bugs have been in the Ceph filesystem code since forever (therefore no "Fixes" tag in this patch). There may be various ways to solve this: - make iput() asynchronous and defer the actual eviction like fput() (may add overhead) - make iput() only asynchronous if I_SYNC is set (doesn't solve random things happening inside the "evict_inode" callback) - add iput_deferred() to make this asynchronous behavior/overhead optional and explicit - refactor Ceph to avoid iput() calls from within writeback and messenger (if that is even possible) - add a Ceph-specific workaround After advice from Mateusz Guzik, I decided to do the latter. The implementation is simple because it piggybacks on the existing work_struct for ceph_queue_inode_work() - ceph_inode_work() calls iput() at the end which means we can donate the last reference to it. Since Ceph has a few iput() callers in a loop, it seemed simple enough to pass this counter and use atomic_sub() instead of atomic_dec(). This patch adds ceph_iput_n_async() and converts lots of iput() calls to it - at least those that may come through writeback and the messenger.

[PATCH 1/1] perf/x86/intel: Fix crash in icl_update_topdown_event()

by Angel Adetula

From: Kan Liang <kan.liang(a)linux.intel.com> [ Upstream commit b0823d5fbacb1c551d793cbfe7af24e0d1fa45ed ] The perf_fuzzer found a hard-lockup crash on a RaptorLake machine: Oops: general protection fault, maybe for address 0xffff89aeceab400: 0000 CPU: 23 UID: 0 PID: 0 Comm: swapper/23 Tainted: [W]=WARN Hardware name: Dell Inc.

The icl_update_topdown_event() should not be invoked on these CPUs. It's a regression of commit: f9bdf1f95339 ("perf/x86/intel: Avoid disable PMU if !cpuc->enabled in sample read") The bug introduced by that commit is that the is_topdown_event() function is mistakenly used to replace the is_topdown_count() call to check if the topdown functions for the perf metrics feature should be invoked. Fix it.
