commit 21a87d88c2253350e115029f14fe2a10a7e6c856 upstream.
If the i_mode field in inode of metadata files is corrupted on disk, it can cause the initialization of bmap structure, which should have been called from nilfs_read_inode_common(), not to be called. This causes a lockdep warning followed by a NULL pointer dereference at nilfs_bmap_lookup_at_level().
This patch fixes these issues by adding a missing sanitiy check for the i_mode field of metadata file's inode.

commit d325dc6eb763c10f591c239550b8c7e5466a5d09 upstream.
If the beginning of the inode bitmap area is corrupted on disk, an inode with the same inode number as the root inode can be allocated and fail soon after. In this case, the subsequent call to nilfs_clear_inode() on that bogus root inode will wrongly decrement the reference counter of struct nilfs_root, and this will erroneously free struct nilfs_root, causing kernel oopses.
This fixes the problem by changing nilfs_new_inode() to skip reserved inode numbers while repairing the inode bitmap.

commit d0d51a97063db4704a5ef6bc978dddab1636a306 upstream.
If nilfs_attach_log_writer() failed to create a log writer thread, it frees a data structure of the log writer without any cleanup. After commit e912a5b66837 ("nilfs2: use root object to get ifile"), this causes a leak of struct nilfs_root, which started to leak an ifile metadata inode and a kobject on that struct.
In addition, if the kernel is booted with panic_on_warn, the above ifile metadata inode leak will cause the following panic when the nilfs2 kernel module is removed:

commit 723ac751208f6d6540191689cfbf6c77135a7a1b upstream.
If creation or finalization of a checkpoint fails due to anomalies in the checkpoint metadata on disk, a kernel warning is generated.
This patch replaces the WARN_ONs by nilfs_error, so that a kernel, booted with panic_on_warn, does not panic. A nilfs_error is appropriate here to handle the abnormal filesystem condition.
This also replaces the detected error codes with an I/O error so that neither of the internal error codes is returned to callers.

commit 2120635108b35ecad9c59c8b44f6cbdf4f98214e upstream.
We enable -Wcast-function-type globally in the kernel to warn about mismatching types in function pointer casts. Compilers currently warn only about ABI incompability with this flag, but Clang 16 will enable a stricter version of the check by default that checks for an exact type match. This will be very noisy in the kernel, so disable -Wcast-function-type-strict without W=1 until the new warnings have been addressed.

commit 8423f0b6d513b259fdab9c9bf4aaa6188d054c2d upstream.
There is a small race window at snd_pcm_oss_sync() that is called from OSS PCM SNDCTL_DSP_SYNC ioctl; namely the function calls snd_pcm_oss_make_ready() at first, then takes the params_lock mutex for the rest. When the stream is set up again by another thread between them, it leads to inconsistency, and may result in unexpected results such as NULL dereference of OSS buffer as a fuzzer spotted recently.
The fix is simply to cover snd_pcm_oss_make_ready() call into the same params_lock mutex with snd_pcm_oss_make_ready_locked() variant.

commit 70cbc3cc78a997d8247b50389d37c4e1736019da upstream.
Since general RCU GUP fast was introduced in commit 2667f50e8b81 ("mm: introduce a general RCU get_user_pages_fast()"), a TLB flush is no longer sufficient to handle concurrent GUP-fast in all cases, it only handles traditional IPI-based GUP-fast correctly. On architectures that send an IPI broadcast on TLB flush, it works as expected. But on the architectures that do not use IPI to broadcast TLB flush, it may have the below race:
CPU A CPU B THP collapse fast GUP gup_pmd_range() <-- see valid pmd gup_pte_range() <-- work on pte pmdp_collapse_flush() <-- clear pmd and flush __collapse_huge_page_isolate() check page pinned <-- before GUP bump refcount pin the page check PTE <-- no change __collapse_huge_page_copy() copy data to huge page ptep_clear() install huge pmd for the huge page return the stale page discard the stale page
The race can be fixed by checking whether PMD is changed or not after taking the page pin in fast GUP, just like what it does for PTE. If the PMD is changed it means there may be parallel THP collapse, so GUP should back off.
Also update the stale comment about serializing against fast GUP in khugepaged.

commit bedf03416913d88c796288f9dca109a53608c745 upstream.
The IPI broadcast is used to serialize against fast-GUP, but fast-GUP will move to use RCU instead of disabling local interrupts in fast-GUP. Using an IPI is the old-styled way of serializing against fast-GUP although it still works as expected now.
And fast-GUP now fixed the potential race with THP collapse by checking whether PMD is changed or not. So IPI broadcast in radix pmd collapse flush is not necessary anymore. But it is still needed for hash TLB.

commit 2e488f13755ffbb60f307e991b27024716a33b29 upstream.
In alloc_inode, inode_init_always() could return -ENOMEM if security_inode_alloc() fails, which causes inode->i_private uninitialized. Then nilfs_is_metadata_file_inode() returns true and nilfs_free_inode() wrongly calls nilfs_mdt_destroy(), which frees the uninitialized inode->i_private and leads to crashes(e.g., UAF/GPF).
Fix this by moving security_inode_alloc just prior to this_cpu_inc(nr_inodes)

Driver moxart-mmc.c has .compatible = "moxa,moxart-mmc".
But moxart .dts/.dtsi and the documentation file moxa,moxart-dma.txt contain compatible = "moxa,moxart-sdhci".
Change moxart .dts/.dtsi files and moxa,moxart-dma.txt to match the driver.
Replace 'sdhci' with 'mmc' in names too, since SDHCI is a different controller from FTSDC010.

[ Upstream commit fbfe96869b782364caebae0445763969ddb6ea67 ]
In __qedf_probe(), if qedf->cdev is NULL which means qed_ops->common->probe() failed, then the program will goto label err1, and scsi_host_put() will free lport->host pointer. Because the memory qedf points to is allocated by libfc_host_alloc(), it will be freed by scsi_host_put(). However, the if statement below label err0 only checks whether qedf is NULL but doesn't check whether the memory has been freed. So a UAF bug can occur.
There are two ways to reach the statements below err0. The first one is described as before, "qedf" should be set to NULL. The second one is goto "err0" directly. In the latter scenario qedf hasn't been changed and it has the initial value NULL. As a result the if statement is not reachable in any situation.
The KASAN logs are as follows:

There is uninit value bug in dgram_sendmsg function in net/ieee802154/socket.c when the length of valid data pointed by the msg->msg_name isn't verified.
We introducing a helper function ieee802154_sockaddr_check_size to check namelen. First we check there is addr_type in ieee802154_addr_sa. Then, we check namelen according to addr_type.
Also fixed in raw_bind, dgram_bind, dgram_connect.

When the user space pcm stream uses the silent stream converter, it is no longer allocated for the silent stream. Clear the appropriate flag in the hdmi_pcm_open() function. The silent stream setup may be applied in hdmi_pcm_close() (and the error path - open fcn) again.
If the flag is not cleared, the reuse conditions for the silent stream converter in hdmi_choose_cvt() may improperly share this converter.

Since binutils 2.39, ld will print a warning if any stack section is executable, which is the default for stack sections on files without a .note.GNU-stack section.
This was fixed for x86 in commit ffcf9c5700e4 ("x86: link vdso and boot with -z noexecstack --no-warn-rwx-segments"), but remained broken for UML, resulting in several warnings:
/usr/bin/ld: warning: arch/x86/um/vdso/vdso.o: missing .note.GNU-stack section implies executable stack /usr/bin/ld: NOTE: This behaviour is deprecated and will be removed in a future version of the linker /usr/bin/ld: warning: .tmp_vmlinux.kallsyms1 has a LOAD segment with RWX permissions /usr/bin/ld: warning: .tmp_vmlinux.kallsyms1.o: missing .note.GNU-stack section implies executable stack /usr/bin/ld: NOTE: This behaviour is deprecated and will be removed in a future version of the linker /usr/bin/ld: warning: .tmp_vmlinux.kallsyms2 has a LOAD segment with RWX permissions /usr/bin/ld: warning: .tmp_vmlinux.kallsyms2.o: missing .note.GNU-stack section implies executable stack /usr/bin/ld: NOTE: This behaviour is deprecated and will be removed in a future version of the linker /usr/bin/ld: warning: vmlinux has a LOAD segment with RWX permissions
Link both the VDSO and vmlinux with -z noexecstack, fixing the warnings about .note.GNU-stack sections. In addition, pass --no-warn-rwx-segments to dodge the remaining warnings about LOAD segments with RWX permissions in the kallsyms objects. (Note that this flag is apparently not available on lld, so hide it behind a test for BFD, which is what the x86 patch does.)

If aq_nic_stop() fails, aq_ndev_close() returns err without calling aq_nic_deinit() to release the relevant memory and resource, which will lead to a memory leak.
We can fix it by deleting the if condition judgment and goto statement to call aq_nic_deinit() directly after aq_nic_stop() to fix the memory leak.

[ Upstream commit e9233917a7e53980664efbc565888163c0a33c3f ]
This loop intends to retry a max of 10 times, with some implicit termination based on the SD_{R,}OCR_S18A bit. Unfortunately, the termination condition depends on the value reported by the SD card (*rocr), which may or may not correctly reflect what we asked it to do.
Needless to say, it's not wise to rely on the card doing what we expect; we should at least terminate the loop regardless. So, check both the input and output values, so we ensure we will terminate regardless of the SD card behavior.
Note that SDIO learned a similar retry loop in commit 0797e5f1453b ("mmc: core: Fixup signal voltage switch"), but that used the 'ocr' result, and so the current pre-terminating condition looks like:
rocr & ocr & R4_18V_PRESENT
(i.e., it doesn't have the same bug.)
This addresses a number of crash reports seen on ChromeOS that look like the following:
... // lots of repeated: ... <4>[13142.846061] mmc1: Skipping voltage switch <4>[13143.406087] mmc1: Skipping voltage switch <4>[13143.964724] mmc1: Skipping voltage switch <4>[13144.526089] mmc1: Skipping voltage switch <4>[13145.086088] mmc1: Skipping voltage switch <4>[13145.645941] mmc1: Skipping voltage switch <3>[13146.153969] INFO: task halt:30352 blocked for more than 122 seconds. ...

commit a659daf63d16aa883be42f3f34ff84235c302198 upstream.
Syzbot found an issue in usbmon module, where the user space client can corrupt the monitor's internal memory, causing the usbmon module to crash the kernel with segfault, UAF, etc.
The reproducer mmaps the /dev/usbmon memory to user space, and overwrites it with arbitrary data, which causes all kinds of issues.
Return an -EPERM error from mon_bin_mmap() if the flag VM_WRTIE is set. Also clear VM_MAYWRITE to make it impossible to change it to writable later.

commit cd4f24ae9404fd31fc461066e57889be3b68641b upstream.
Prior to 5.6, when /dev/random was opened with O_NONBLOCK, it would return -EAGAIN if there was no entropy. When the pools were unified in 5.6, this was lost. The post 5.6 behavior of blocking until the pool is initialized, and ignoring O_NONBLOCK in the process, went unnoticed, with no reports about the regression received for two and a half years. However, eventually this indeed did break somebody's userspace.
So we restore the old behavior, by returning -EAGAIN if the pool is not initialized. Unlike the old /dev/random, this can only occur during early boot, after which it never blocks again.
In order to make this O_NONBLOCK behavior consistent with other expectations, also respect users reading with preadv2(RWF_NOWAIT) and similar.

commit 56e696c0f0c71b77fff921fc94b58a02f0445b2c upstream.
Hans reported that his Sony VAIO VPX11S1E showed the broken sound behavior at the start of the stream for a couple of seconds, and it turned out that the position_fix=1 option fixes the issue. It implies that the position reporting is inaccurate, and very likely hitting on all Poulsbo devices.
The patch applies the workaround for Poulsbo generically to switch to LPIB mode instead of the default position buffer.

commit bab715bdaa9ebf28d99a6d1efb2704a30125e96d upstream.
It turns out Apple doesn't capitalise the "mini" in "Macmini" in DMI, which is inconsistent with other model line names.
Correct the capitalisation of Macmini in the quirk for skipping loading platform certs on T2 Macs.
Currently users get:

The passthrough structure is declared off of the stack, so it needs to be set to zero before copied back to userspace to prevent any unintentional data leakage. Switch things to be statically allocated which will fill the unused fields with 0 automatically.

commit 9ee0507e896b45af6d65408c77815800bce30008 upstream.
In order to avoid reading and dirtying two cache lines on every IRQ, move the work_struct to the bottom of the fast_pool struct. add_ interrupt_randomness() always touches .pool and .count, which are currently split, because .mix pushes everything down. Instead, move .mix to the bottom, so that .pool and .count are always in the first cache line, since .mix is only accessed when the pool is full.

commit 748bc4dd9e663f23448d8ad7e58c011a67ea1eca upstream.
Previously, the fast pool was dumped into the main pool periodically in the fast pool's hard IRQ handler. This worked fine and there weren't problems with it, until RT came around. Since RT converts spinlocks into sleeping locks, problems cropped up. Rather than switching to raw spinlocks, the RT developers preferred we make the transformation from originally doing:
do_some_stuff() spin_lock() do_some_other_stuff() spin_unlock()
to doing:
do_some_stuff() queue_work_on(some_other_stuff_worker)
This is an ordinary pattern done all over the kernel. However, Sherry noticed a 10% performance regression in qperf TCP over a 40gbps InfiniBand card. Quoting her message:
MT27500 Family [ConnectX-3] cards: Infiniband device 'mlx4_0' port 1 status: default gid: fe80:0000:0000:0000:0010:e000:0178:9eb1 base lid: 0x6 sm lid: 0x1 state: 4: ACTIVE phys state: 5: LinkUp rate: 40 Gb/sec (4X QDR) link_layer: InfiniBand
Cards are configured with IP addresses on private subnet for IPoIB performance testing. Regression identified in this bug is in TCP latency in this stack as reported by qperf tcp_lat metric:
We have one system listen as a qperf server: [root@yourQperfServer ~]# qperf
Have the other system connect to qperf server as a client (in this case, it’s X7 server with Mellanox card): [root@yourQperfClient ~]# numactl -m0 -N0 qperf 20.20.20.101 -v -uu -ub --time 60 --wait_server 20 -oo msg_size:4K:1024K:*2 tcp_lat
Rather than incur the scheduling latency from queue_work_on, we can instead switch to running on the next timer tick, on the same core. This also batches things a bit more -- once per jiffy -- which is okay now that mix_interrupt_randomness() can credit multiple bits at once.

commit aebe9f4639b13a1f4e9a6b42cdd2e38c617b442d upstream.
In the copy code of the elements, we do the following calculation to reach the end of the MBSSID element:
/* copy the IEs after MBSSID */ cpy_len = mbssid[1] + 2;
This looks fine, however, cpy_len is a u8, the same as mbssid[1], so the addition of two can overflow. In this case the subsequent memcpy() will overflow the allocated buffer, since it copies 256 bytes too much due to the way the allocation and memcpy() sizes are calculated.
Fix this by using size_t for the cpy_len variable.
This fixes CVE-2022-41674.

commit 8f033d2becc24aa6bfd2a5c104407963560caabc upstream.
Per spec, the maximum value for the MaxBSSID ('n') indicator is 8, and the minimum is 1 since a multiple BSSID set with just one BSSID doesn't make sense (the # of BSSIDs is limited by 2^n).
Limit this in the parsing in both cfg80211 and mac80211, rejecting any elements with an invalid value.
This fixes potentially bad shifts in the processing of these inside the cfg80211_gen_new_bssid() function later.
I found this during the investigation of CVE-2022-41674 fixed by the previous patch.

commit 0b7808818cb9df6680f98996b8e9a439fa7bcc2f upstream.
There are multiple refcounting bugs related to multi-BSSID: - In bss_ref_get(), if the BSS has a hidden_beacon_bss, then the bss pointer is overwritten before checking for the transmitted BSS, which is clearly wrong. Fix this by using the bss_from_pub() macro.
- In cfg80211_bss_update() we copy the transmitted_bss pointer from tmp into new, but then if we release new, we'll unref it erroneously. We already set the pointer and ref it, but need to NULL it since it was copied from the tmp data.
- In cfg80211_inform_single_bss_data(), if adding to the non- transmitted list fails, we unlink the BSS and yet still we return it, but this results in returning an entry without a reference. We shouldn't return it anyway if it was broken enough to not get added there.
This fixes CVE-2022-42720.

If a non-transmitted BSS shares enough information (both SSID and BSSID!) with another non-transmitted BSS of a different AP, then we can find and update it, and then try to add it to the non-transmitted BSS list. We do a search for it on the transmitted BSS, but if it's not there (but belongs to another transmitted BSS), the list gets corrupted.
Since this is an erroneous situation, simply fail the list insertion in this case and free the non-transmitted BSS.

commit b2d03cabe2b2e150ff5a381731ea0355459be09f upstream.
If beacon protection is active but the beacon cannot be decrypted or is otherwise malformed, we call the cfg80211 API to report this to userspace, but that uses a netdev pointer, which isn't present for P2P-Device. Fix this to call it only conditionally to ensure cfg80211 won't crash in the case of P2P-Device.
This fixes CVE-2022-42722.

commit c90b93b5b782891ebfda49d4e5da36632fefd5d1 upstream.
When updating beacon elements in a non-transmitted BSS, also update the hidden sub-entries to the same beacon elements, so that a future update through other paths won't trigger a WARN_ON().
The warning is triggered because the beacon elements in the hidden BSSes that are children of the BSS should always be the same as in the parent.

commit a17b9841152e7f4621619902b347e2cc39c32996 upstream.
Suspending and resuming the system can sometimes cause the out URB to get hung after a reset_resume. This causes LED setting and force feedback to break on resume. To avoid this, just drop the reset_resume callback so the USB core rebinds xpad to the wireless pads on resume if a reset happened.
A nice side effect of this change is the LED ring on wireless controllers is now set correctly on system resume.

Compiled and booted on my test system. No dmesg regressions.
Tested-by: Shuah Khan skhan@linuxfoundation.org
Just a note: I am debugging drm issue from a previous rc (5.10.146) and I will let you know once I bisect and figure the offending patch.
This is not related to this rc - doesn't stop from releasing this one.
thanks, -- Shuah
