2024-06-13scsi: usb: uas: Do not query the IO Advice Hints Grouping mode page for ↵Bart Van Assche2-0/+13
USB/UAS devices Recently it was reported that the following USB storage devices are unusable with Linux kernel 6.9: * Kingston DataTraveler G2 * Garmin FR35 This is because attempting to read the IO Advice Hints Grouping mode page causes these devices to reset. Hence do not read the IO Advice Hints Grouping mode page from USB/UAS storage devices.

2024-06-13scsi: ufs: core: Free memory allocated for model before reinitJoel Slebodnick1-0/+1
Under the conditions that a device is to be reinitialized within ufshcd_probe_hba(), the device must first be fully reset. Resetting the device should include freeing U8 model (member of dev_info) but does not, and this causes a memory leak. ufs_put_device_desc() is responsible for freeing model. unreferenced object 0xffff3f63008bee60 (size 32): comm "kworker/u33:1", pid 60, jiffies 4294892642 hex dump (first 32 bytes): 54 48 47 4a 46 47 54 30 54 32 35 42 41 5a 5a 41 THGJFGT0T25BAZZA 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 00 ................ backtrace (crc ed7ff1a9): [<ffffb86705f1243c>] kmemleak_alloc+0x34/0x40 [<ffffb8670511cee4>] __kmalloc_noprof+0x1e4/0x2fc [<ffffb86705c247fc>] ufshcd_read_string_desc+0x94/0x190 [<ffffb86705c26854>] ufshcd_device_init+0x480/0xdf8 [<ffffb86705c27b68>] ufshcd_probe_hba+0x3c/0x404 [<ffffb86705c29264>] ufshcd_async_scan+0x40/0x370 [<ffffb86704f43e9c>] async_run_entry_fn+0x34/0xe0 [<ffffb86704f34638>] process_one_work+0x154/0x298 [<ffffb86704f34a74>] worker_thread+0x2f8/0x408 [<ffffb86704f3cfa4>] kthread+0x114/0x118 [<ffffb86704e955a0>] ret_from_fork+0x10/0x20 Fixes: 96a7141da332 ("scsi: ufs: core: Add support for reinitializing the UFS device") Cc: <[email protected]> Reviewed-by: Andrew Halaney <[email protected]> Reviewed-by: Bart Van Assche <[email protected]> Signed-off-by: Joel Slebodnick <[email protected]> Link: https://lore.kernel.org/r/[email protected] Signed-off-by: Martin K.

As btrfs/167 is doing a NOCOW write this is to be expected. Further analysis with drgn confirmed the assumption: >>> inode = prog.crashed_thread().stack_trace()[11]['ordered'].inode >>> btrfs_inode = drgn.container_of(inode, "struct btrfs_inode", \ "vfs_inode") >>> print(btrfs_inode.flags) (u32)1 As zoned emulation mode simulates conventional zones on regular devices, we cannot use zone-append for writing. But we're only attaching dummy checksums if we're doing a zone-append write. So for NOCOW zoned data writes on conventional zones, also attach a dummy checksum.

2024-06-13btrfs: retry block group reclaim without infinite loopBoris Burkov1-2/+9
If inc_block_group_ro systematically fails (e.g. due to ETXTBUSY from swap) or btrfs_relocate_chunk systematically fails (from lack of space), then this worker becomes an infinite loop. At the very least, this strands the cleaner thread, but can also result in hung tasks/RCU stalls on PREEMPT_NONE kernels and if the reclaim_bgs_lock mutex is not contended. I believe the best long term fix is to manage reclaim via work queue, where we queue up a relocation on the triggering condition and re-queue on failure. In the meantime, this is an easy fix to apply to avoid the immediate pain.

This implies a possible sleep and violates limitations of RCU read-side critical sections on non-PREEMPT systems. Sleeping within RCU read-side critical section might cause synchronize_rcu() returning early and break RCU protection, allowing a UAF to happen. The root cause of this issue could be described as follows: | Thread A | Thread B | | |ima_match_policy | | | rcu_read_lock | |ima_lsm_update_rule | | | synchronize_rcu | | | | kmalloc(GFP_KERNEL)| | | sleep | ==> synchronize_rcu returns early | kfree(entry) | | | | entry = entry->next| ==> UAF happens and entry now becomes NULL (or could be anything). | | entry->action | ==> Accessing entry might cause panic. To fix this issue, we are converting all kmalloc that is called within RCU read-side critical section to use GFP_ATOMIC.

After the binary-or in line 18, the verifier knows that bit 2 is set but knows nothing about the rest of the content which was loaded from a map value, meaning, range is [2,0x7fffffff] with var_off=(0x2; 0x7ffffffd). When in line 19 the verifier analyzes the branch, it splits the register states in reg_set_min_max() into the registers of the true branch (true_reg1, true_reg2) and the registers of the false branch (false_reg1, false_reg2). Since the test is w6 != 0x7ffffffd, the src_reg is a known constant. Internally, the verifier creates a "fake" register initialized as scalar to the value of 0x7ffffffd, and then passes it onto reg_set_min_max(). Now, for line 19, it is mathematically impossible to take the false branch of this program, yet the verifier analyzes it. It is impossible because the second bit of r6 will be set due to the prior or operation and the constant in the condition has that bit unset (hex(fd) == binary(1111 1101). When the verifier first analyzes the false / fall-through branch, it will compute an intersection between the var_off of r6 and of the constant. This is because the verifier creates a "fake" register initialized to the value of the constant. The intersection result later refines both registers in regs_refine_cond_op(): [...] t = tnum_intersect(tnum_subreg(reg1->var_off), tnum_subreg(reg2->var_off)); reg1->var_off = tnum_with_subreg(reg1->var_off, t); reg2->var_off = tnum_with_subreg(reg2->var_off, t); [...] Since the verifier is analyzing the false branch of the conditional jump, reg1 is equal to false_reg1 and reg2 is equal to false_reg2, i.e. the reg2 is the "fake" register that was meant to hold a constant value. The resulting var_off of the intersection says that both registers now hold a known value of var_off=(0x7fffffff, 0x0) or in other words: this operation manages to make the verifier think that the "constant" value that was passed in the jump operation now holds a different value. Normally this would not be an issue since it should not influence the true branch, however, false_reg2 and true_reg2 are pointers to the same "fake" register. Meaning, the false branch can influence the results of the true branch. In line 24, the verifier assumes R6_w=0, but the actual runtime value in this case is 1. The fix is simply not passing in the same "fake" register location as inputs to reg_set_min_max(), but instead making a copy. Moving the fake_reg into the env also reduces stack consumption by 120 bytes. With this, the verifier successfully rejects invalid accesses from the test program.

2024-06-13ice: avoid IRQ collision to fix init failure on ACPI S3 resumeEn-Wei Wu1-1/+6
A bug in https://bugzilla.kernel.org/show_bug.cgi?id=218906 describes that irdma would break and report hardware initialization failed after suspend/resume with Intel E810 NIC (tested on 6.9.0-rc5). The problem is caused due to the collision between the irq numbers requested in irdma and the irq numbers requested in other drivers after suspend/resume. The irq numbers used by irdma are derived from ice's ice_pf->msix_entries which stores mappings between MSI-X index and Linux interrupt number. It's supposed to be cleaned up when suspend and rebuilt in resume but it's not, causing irdma using the old irq numbers stored in the old ice_pf->msix_entries to request_irq() when resume. And eventually collide with other drivers. This patch fixes this problem. On suspend, we call ice_deinit_rdma() to clean up the ice_pf->msix_entries (and free the MSI-X vectors used by irdma if we've dynamically allocated them). On resume, we call ice_init_rdma() to rebuild the ice_pf->msix_entries (and allocate the MSI-X vectors if we would like to dynamically allocate them).

This issue is expected to be prevented by HWRM_ERR_CODE_PF_UNAVAILABLE error code. But this error code is returned by recent firmware. So some firmware may not return it.

2024-06-13bnxt_en: Cap the size of HWRM_PORT_PHY_QCFG forwarded responseMichael Chan2-2/+61
Firmware interface 1.10.2.118 has increased the size of HWRM_PORT_PHY_QCFG response beyond the maximum size that can be forwarded. When the VF's link state is not the default auto state, the PF will need to forward the response back to the VF to indicate the forced state. This regression may cause the VF to fail to initialize. Fix it by capping the HWRM_PORT_PHY_QCFG response to the maximum 96 bytes. The SPEEDS2_SUPPORTED flag needs to be cleared because the new speeds2 fields are beyond the legacy structure. Also modify bnxt_hwrm_fwd_resp() to print a warning if the message size exceeds 96 bytes to make this failure more obvious.

Some editors (like the vim variants), when seeing "trim_whitespace" decide to do just that for all of the whitespace in the file you are saving, even if it is not on a line that you have modified. This plays havoc with diffs and is NOT something that should be intended. As the "only trim whitespace on modified lines" is not part of the editorconfig standard yet, just delete these lines from the .editorconfig file so that we don't end up with diffs that are automatically rejected by maintainers for containing things they shouldn't.

2024-06-13ionic: fix use after netif_napi_del()Taehee Yoo1-3/+1
When queues are started, netif_napi_add() and napi_enable() are called. If there are 4 queues and only 3 queues are used for the current configuration, only 3 queues' napi should be registered and enabled. The ionic_qcq_enable() checks whether the .poll pointer is not NULL for enabling only the using queue' napi. Unused queues' napi will not be registered by netif_napi_add(), so the .poll pointer indicates NULL. But it couldn't distinguish whether the napi was unregistered or not because netif_napi_del() doesn't reset the .poll pointer to NULL. So, ionic_qcq_enable() calls napi_enable() for the queue, which was unregistered by netif_napi_del().

2024-06-13ACPI: EC: Evaluate orphan _REG under EC deviceRafael J. Wysocki5-5/+66
After starting to install the EC address space handler at the ACPI namespace root, if there is an "orphan" _REG method in the EC device's scope, it will not be evaluated any more. This breaks EC operation regions on some systems, like Asus gu605. To address this, use a wrapper around an existing ACPICA function to look for an "orphan" _REG method in the EC device scope and evaluate it if present.

This is a re-commit of da05b143a308 ("x86/boot: Don't add the EFI stub to targets") after the tagged patch incorrectly reverted it. vmlinux-objs-y is added to targets, with an assumption that they are all relative to $(obj); adding a $(objtree)/drivers/... path causes the build to incorrectly create a useless arch/x86/boot/compressed/drivers/... directory tree. Fix this just by using a different make variable for the EFI stub.

Nikolay Aleksandrov says: ==================== net: bridge: mst: fix suspicious rcu usage warning This set fixes a suspicious RCU usage warning triggered by syzbot[1] in the bridge's MST code. After I converted br_mst_set_state to RCU, I forgot to update the vlan group dereference helper. Fix it by using the proper helper, in order to do that we need to pass the vlan group which is already obtained correctly by the callers for their respective context. Patch 01 is a requirement for the fix in patch 02. Note I did consider rcu_dereference_rtnl() but the churn is much bigger and in every part of the bridge. We can do that as a cleanup in net-next.

2024-06-12net/ipv6: Fix the RT cache flush via sysctl using a previous delayPetr Pavlu1-2/+2
The net.ipv6.route.flush system parameter takes a value which specifies a delay used during the flush operation for aging exception routes. The written value is however not used in the currently requested flush and instead utilized only in the next one. A problem is that ipv6_sysctl_rtcache_flush() first reads the old value of net->ipv6.sysctl.flush_delay into a local delay variable and then calls proc_dointvec() which actually updates the sysctl based on the provided input. Fix the problem by switching the order of the two operations. Fixes: 4990509f19e8 ("[NETNS][IPV6]: Make sysctls route per namespace.")
