Specifically adreno_runtime_resume() will eventually call a6xx_pm_resume() and that may try to resume the gmu. Let's grab the GMU lock as we're destroying the GMU. That will solve the race because a6xx_pm_resume() grabs the same lock. That makes the access of `gmu->initialized` in a6xx_gmu_resume() safe.

However, some low-level HID drivers allocate a reduced amount of memory to their buffers (e.g. UHID only allocates UHID_DATA_MAX (4k) buffers), rending this check inadequate in some cases. In these circumstances, if the received report ends up being smaller than the proposed report size, the remainder of the buffer is zeroed. That is, the space between sizeof(csize) (size of the current report) and the rsize (size proposed i.e. Report Size * Report Count), which can be handled up to HID_MAX_BUFFER_SIZE (16k). Meaning that memset() shoots straight past the end of the buffer boundary and starts zeroing out in-use values, often resulting in calamity. This patch introduces a new variable into 'struct hid_ll_driver' where individual low-level drivers can over-ride the default maximum value of HID_MAX_BUFFER_SIZE (16k) with something more sympathetic to the interface.

Defining the second CPU port in the device tree should not cause any compatibility issue, because the default CPU port was &seville_port8 before this change, and still is &seville_port8 now (the numerically first CPU port is used by default).

Even tho both before and after the change 'decrypted' was updated inside the main loop, it was completely overwritten when processing the async completions. Now that the rx_list only holds non-zero-copy records we need to add, not overwrite.

With SK_RECLAIM_THRESHOLD checks gone number of calls to enter/leave memory pressure happen much more often. For TCP indirect calls are used. We can't remove the if-set-return short-circuit check in tcp_enter_memory_pressure because there are callers other than sk_enter_memory_pressure. Doing a check in the sk wrapper too reduces the indirect calls enough to recover some performance.

In this change, we add a new field 'initial_delay' for struct target which could be shared by other subcommands. And define target__enable_on_exec() which returns whether enable_on_exec should be set on normal cases.

Fix the error reported by Enguerrand de Ribaucourt in December 2022, "Some operations during the cable switch workaround modify the register LAN88XX_INT_MASK of the PHY. However, this register is specific to the LAN8835 PHY. For instance, if a DP8322I PHY is connected to the LAN7801, that register (0x19), corresponds to the LED and MAC address configuration, resulting in unapropriate behavior." I did not test with the DP8322I PHY, but I tested with an EVB-LAN7800 with the internal PHY.

Later on, devices in the todo list are processed by netdev_run_todo(). netdev_run_todo() waits devices' reference count become 1 while rebdoadcasting NETDEV_UNREGISTER notification. When cfusbl_device_notify() is called with NETDEV_UNREGISTER multiple times, the parent device might be freed. This could cause UAF. Processing NETDEV_UNREGISTER multiple times also causes inbalance of reference count for the module. This patch fixes the issue by accepting only first NETDEV_UNREGISTER notification.

According to the Linux system call man page, 0 should be returned in this case. Therefore, in tcp_bpf_recvmsg_parser(), if the length is 0, directly return.

A mistake was made in using round_up(pos) for the end offset, because when pos points at the first byte of a block, it does not get rounded up to point to the end byte of the block. hence the punch range is short, and this leads to unexpected behaviour in certain cases in xfs_bmap_punch_delalloc_range. e.g. pos = 0 means we call xfs_bmap_punch_delalloc_range(0,0), so there is no previous extent and it rounds up the punch to the end of the delalloc extent it found at offset 0, not the end of the range given to xfs_bmap_punch_delalloc_range(). Fix this by handling the zero block offset case correctly.

This is expected cause a bus error exception on e.g. NULL pointer dereferencing when logging a kernel task has no workqueue associated. This bus error ought to be ignored. Our 030 bus error handler is ill equipped to deal with this: Whenever ssw indicates a kernel mode access on a data fault, we don't even attempt to handle the fault and instead always send a SEGV signal (or panic). As a result, the check for exception handling at the fault PC (buried in send_sig_fault() which gets called from do_page_fault() eventually) is never used. In contrast, both 040 and 060 access error handlers do not care whether a fault happened on supervisor mode access, and will call do_page_fault() on those, ultimately honoring the exception table. Add a check in bus_error030 to call do_page_fault() in case we do have an entry for the fault PC in our exception table. I had attempted a fix for this earlier in 2019 that did rely on testing pagefault_disabled() (see link below) to achieve the same thing, but this patch should be more generic. Tested on 030 Atari Falcon.

The locking there is unconditional, even if ->skip_locking and ->search_commit_root is set. It's not meant to be used for commit roots, so it always needs to do locking. So if another task is COWing a child node of the same root node and then needs to wait for block group caching to complete when trying to allocate a metadata extent, it deadlocks.

But the returned info is not enough to determine if a device is a seed. Commit a26d60dedf9a ("btrfs: sysfs: add devinfo/fsid to retrieve actual fsid from the device") exports the same value in sysfs so this is for parity with ioctl. Add a new member, fsid, into btrfs_ioctl_dev_info_args, and populate the member with fsid value. This should not cause any compatibility problem, following the combinations: - Old user space, old kernel - Old user space, new kernel User space tool won't even check the new member. - New user space, old kernel The kernel won't touch the new member, and user space tool should zero out its argument, thus the new member is all zero. User space tool can then know the kernel doesn't support this fsid reporting, and falls back to whatever they can. - New user space, new kernel Go as planned. Would find the fsid member is no longer zero, and trust its value.

In practice this has no consequences, because EXTENT_FLAG_LOGGING should not be set when btrfs_drop_extent_map_range() is called, as an fsync locks the inode in exclusive mode, locks the inode's mmap semaphore in exclusive mode too and it always flushes all delalloc.

IOW, the following: for (u32 i = 0; i < 0xdead; i++) { xdpf = xdp_convert_buff_to_frame(&xdp); xdp_convert_frame_to_buff(xdpf, &xdp); } shouldn't ever modify @xdpf's contents or the pointer itself. However, "live packet" code wrongly treats &xdp_frame as part of its context placed *before* the data_hard_start. With such flow, data_hard_start is sizeof(*xdpf) off to the right and no longer points to the XDP frame. Instead of replacing `sizeof(ctx)` with `offsetof(ctx, xdpf)` in several places and praying that there are no more miscalcs left somewhere in the code, unionize ::frm with ::data in a flex array, so that both starts pointing to the actual data_hard_start and the XDP frame actually starts being a part of it, i.e. a part of the headroom, not the context. A nice side effect is that the maximum frame size for this mode gets increased by 40 bytes, as xdp_buff::frame_sz includes everything from data_hard_start (-> includes xdpf already) to the end of XDP/skb shared info. Also update %MAX_PKT_SIZE accordingly in the selftests code. Leave it hardcoded for 64 bit && 4k pages, it can be made more flexible later on. Minor: align `&head->data` with how `head->frm` is assigned for consistency. Minor #2: rename 'frm' to 'frame' in &xdp_page_head while at it for clarity.

The reason is that env_stack_push is never executed for the second VAR. if (!env_type_is_resolve_sink(env, var_type) && !env_type_is_resolved(env, var_type_id)) { env_stack_set_next_member(env, i + 1); return env_stack_push(env, var_type, var_type_id); } env_type_is_resolve_sink() changes its behaviour based on resolve_mode. For RESOLVE_PTR, we can simplify the if condition to the following: (btf_type_is_modifier() || btf_type_is_ptr) && !env_type_is_resolved() Since we're dealing with a VAR the clause evaluates to false. This is not sufficient to trigger the bug however. The log output and EINVAL are only generated if btf_type_id_size() fails. if (!btf_type_id_size(btf, &type_id, &type_size)) { btf_verifier_log_vsi(env, v->t, vsi, "Invalid type"); return -EINVAL; } Most types are sized, so for example a VAR referring to an INT is not a problem. The bug is only triggered if a VAR points at a modifier. Since we skipped btf_var_resolve that modifier was also never resolved, which means that btf_resolved_type_id returns 0 aka VOID for the modifier. This in turn causes btf_type_id_size to return NULL, triggering EINVAL. To summarise, the following conditions are necessary: - VAR pointing at PTR, STRUCT, UNION or ARRAY - Followed by a VAR pointing at TYPEDEF, VOLATILE, CONST, RESTRICT or TYPE_TAG The fix is to reset resolve_mode to RESOLVE_TBD before attempting to resolve a VAR from a DATASEC.

The documented correct check for "no more cpus in the cpumask" is to check for the result being equal or larger than the number of possible CPU ids, exactly _because_ we've always done those constant-sized cpumask scans using a widened type before. So the return value of a cpumask scan should be checked with if (cpu >= nr_cpu_ids) ... because the cpumask scan did not necessarily stop exactly *at* that maximum CPU id. But a few cases ended up instead using checks like if (cpu == nr_cpumask_bits) ... which used that internal "widened" number of bits. And that used to work pretty much by accident (ok, in this case "by accident" is simply because it matched the historical internal implementation of the cpumask scanning, so it was more of a "intentionally using implementation details rather than an accident"). But the extended constant-sized optimizations then did that internal implementation differently, and now that code that did things wrong but matched the old implementation no longer worked at all. Which then causes subsequent odd problems due to using what ends up being an invalid CPU ID. Most of these cases require either unusual hardware or special uses to hit, but the random.c one triggers quite easily. All you really need is to have a sufficiently small CONFIG_NR_CPUS value for the bit scanning optimization to be triggered, but not enough CPUs to then actually fill that widened cpumask. At that point, the cpumask scanning will return the NR_CPUS constant, which is _not_ the same as nr_cpumask_bits. This just does the mindless fix with sed -i 's/== nr_cpumask_bits/>= nr_cpu_ids/' to fix the incorrect uses. The ones in the SCSI lpfc driver in particular could probably be fixed more cleanly by just removing that repeated pattern entirely, but I am not emptionally invested enough in that driver to care.

The VHD/VHDX file format is a sparse format where real disk space on the host is assigned in chunks that the VHD/VHDX file format calls the BlockSize. This BlockSize is not to be confused with the 512-byte (or 4096-byte) sector size of the underlying storage device. The default block size for a new VHD/VHDX file is 32 Mbytes. When a guest VM touches any disk space within a 32 Mbyte chunk of the VHD/VHDX file, Hyper-V allocates 32 Mbytes of real disk space for that section of the VHD/VHDX. Similarly, if a discard operation is done that covers an entire 32 Mbyte chunk, Hyper-V will free the real disk space for that portion of the VHD/VHDX. This BlockSize is surfaced in Linux as the "discard_granularity" in /sys/block/sd/queue, which makes sense. Hyper-V also has differencing disks that can overlay a VHD/VHDX file to capture changes to the VHD/VHDX while preserving the original VHD/VHDX. One example of this differencing functionality is for VM snapshots. When a snapshot is created, a differencing disk is created. If the snapshot is rolled back, Hyper-V can just delete the differencing disk, and the VM will see the original disk contents at the time the snapshot was taken. Differencing disks are used in other scenarios as well. The BlockSize for a differencing disk defaults to 2 Mbytes, not 32 Mbytes. The smaller default is used because changes to differencing disks are typically scattered all over, and Hyper-V doesn't want to allocate 32 Mbytes of real disk space for a stray write here or there. The smaller BlockSize provides more efficient use of real disk space. When a differencing disk is added to a VHD/VHDX, Hyper-V reports UNIT_ATTENTION with a sense code indicating "Operating parameters have changed", because the value of discard_granularity should be changed to 2 Mbytes. When the differencing disk is removed, discard_granularity should be changed back to 32 Mbytes. However, current code simply reports a message from scsi_report_sense() and the value of /sys/block/sd/queue/discard_granularity is not updated. The message isn't very actionable by a sysadmin. Fix this by having the storvsc driver check for the sense code indicating that the underly VHD/VHDX block size has changed, and do a rescan of the device to pick up the new discard_granularity. With this change the entire transition to/from differencing disks is handled automatically and transparently, with no confusing messages being output.

After that, the sd driver overwrites the value in sd_zbc_read_zone() with the physical block size, since ZBC/ZAC requires this for host-managed disks. Between the calls to disk_set_zoned() and sd_zbc_read_zone(), there exists a window where the attribute shows the logical block size as the zone_write_granularity value, which is wrong for host-managed disks. The duration of the window is from 20ms to 200ms, depending on report zone command execution time. To avoid the wrong zone_write_granularity value between disk_set_zoned() and sd_zbc_read_zone(), modify the value not in sd_zbc_read_zone() but just after disk_set_zoned() call.

However, Yury correctly points out that while "bitmap_set()" does indeed only set bits up to the required bitmap size, it doesn't _clear_ bits above that size, so the upper bits would still not have well-defined values. Now, none of this should really matter, since any bits set past 'nr_cpu_ids' should always be ignored in the first place. Yes, the bit scanning functions might return them as a result, but since users should always consider the ">= nr_cpu_ids" condition to mean "no more bits", that shouldn't have any actual effect (see previous commit 8ca09d5fa354 "cpumask: fix incorrect cpumask scanning result checks"). But let's just do it right, the way the code was _intended_ to work. We have had enough lazy code that works but bites us in the *rse later (again, see previous commit) that there's no reason to not just do this properly. It turns out that "bitmap_fill()" gets this all right for the complex case, and really only fails for the inlined optimized case that just fills the whole word. And while we could just fix bitmap_fill() to use the proper last word mask, there's two issues with that: - the cpumask case wants to do the _optimization_ based on "NR_CPUS is a small constant", but then wants to do the actual bit _fill_ based on "nr_cpu_ids" that isn't necessarily that same constant - we have lots of non-cpumask users of bitmap_fill(), and while they hopefully don't care, and probably would want the proper semantics anyway ("only set bits up to the limit"), I do not want the cpumask changes to impact other parts So this ends up just doing the single-word optimization by hand in the cpumask code. If our cpumask is fundamentally limited to a single word, just do the proper "fill in that word" exactly. And if it's the more complex multi-word case, then the generic bitmap_fill() will DTRT. This is all an example of how our bitmap function optimizations really are somewhat broken. They conflate the "this is size of the bitmap" optimizations with the actual bit(s) we want to set. In many cases we really want to have the two be separate things: sometimes we base our optimizations on the size of the whole bitmap ("I know this whole bitmap fits in a single word, so I'll just use single-word accesses"), and sometimes we base them on the bit we are looking at ("this is just acting on bits that are in the first word, so I'll use single-word accesses"). Notice how the end result of the two optimizations are the same, but the way we get to them are quite different. And all our cpumask optimization games are really about that fundamental distinction, and we'd often really want to pass in both the "this is the bit I'm working on" (which _can_ be a small constant but might be variable), and "I know it's in this range even if it's variable" (based on CONFIG_NR_CPUS). So this cpumask_setall() implementation just makes that explicit. It checks the "I statically know the size is small" using the known static size of the cpumask (which is what that 'small_cpumask_bits' is all about), but then sets the actual bits using the exact number of cpus we have (ie 'nr_cpumask_bits') Of course, in a perfect world, the compiler would have done all the range analysis (possibly with help from us just telling it that "this value is always in this range"), and would do all of this for us.

Userspace is expected to read the EDID and set an appropriate HDR_OUTPUT_METADATA. In drm_parse_hdr_metadata_block the kernel reads the supported EOTFs from the EDID and stores them in the drm_connector->hdr_sink_metadata. While doing so it also filters the EOTFs to the EOTFs the kernel knows about. When an HDR_OUTPUT_METADATA is set it then checks to make sure the EOTF is a supported EOTF. In cases where the kernel doesn't know about a new EOTF this check will fail, even if the EDID advertises support. Since it is expected that userspace reads the EDID to understand what the display supports it doesn't make sense for DRM to block an HDR_OUTPUT_METADATA if it contains an EOTF the kernel doesn't understand. This comes with the added benefit of future-proofing metadata support. If the spec defines a new EOTF there is no need to update DRM and an compositor can immediately make use of it.

This happens if for the new allocated block group, in the same transaction that created the block group, we have tasks allocating extents from it as well as tasks removing extents from it. For example: 1) Task A creates a metadata block group X; 2) Two extents are allocated from block group X, so its "used" field is updated to 32K, and its "commit_used" field remains as 0; 3) Transaction commit starts, by some task B, and it enters btrfs_start_dirty_block_groups(). There it tries to update the block group item for block group X, which currently has its "used" field with a value of 32K. But that fails since the block group item was not yet inserted, and so on failure update_block_group_item() sets the "commit_used" field of the block group back to 0; 4) The block group item is inserted by task A, when for example btrfs_create_pending_block_groups() is called when releasing its transaction handle. This results in insert_block_group_item() inserting the block group item in the extent tree (or block group tree), with a "used" field having a value of 32K, but without updating the "commit_used" field in the block group, which remains with value of 0; 5) The two extents are freed from block X, so its "used" field changes from 32K to 0; 6) The transaction commit by task B continues, it enters btrfs_write_dirty_block_groups() which calls update_block_group_item() for block group X, and there it decides to skip the block group item update, because "used" has a value of 0 and "commit_used" has a value of 0 too. As a result, we end up with a block item having a 32K "used" field but no extents allocated from it. When this issue happens, a btrfs check reports an error like this: [1/7] checking root items [2/7] checking extents block group [1104150528 1073741824] used 39796736 but extent items used 0 ERROR: errors found in extent allocation tree or chunk allocation (...)

It also passes the bounce page to wbc_account_cgroup_owner(). That's incorrect, because the bounce page is a newly allocated temporary page that doesn't have the memory cgroup of the original pagecache page. This makes wbc_account_cgroup_owner() not account the I/O to the owner of the pagecache page as it should. Fix this by always passing the pagecache page to wbc_account_cgroup_owner().

An example: "EXT4-fs warning (device vdc): ext4_dirblock_csum_set:425: inode #16385: comm fsstress: No space for directory leaf checksum. Please run e2fsck -D." The xfstests include: ext4/057, 058, and 307; generic/013, 051, 068, 070, 076, 078, 083, 232, 269, 270, 390, 461, 475, 476, 482, 579, 585, 589, 626, 631, and 650. In this situation, the warning message indicates a bug in the code that performs the RENAME_WHITEOUT operation on a directory entry that has been stored inline. It doesn't detect that the directory is stored inline, and incorrectly attempts to compute a dirent block checksum on the whiteout inode when creating it. This attempt fails as a result of the integrity checking in get_dirent_tail (usually due to a failure to match the EXT4_FT_DIR_CSUM magic cookie), and the warning message is then emitted. Fix this by simply collecting the inlined data state at the time the search for the source directory entry is performed. Existing code handles the rest, and this is sufficient to eliminate all spurious warning messages produced by the tests above. Go one step further and do the same in the code that resets the source directory entry in the event of failure. The inlined state should be present in the "old" struct, but given the possibility of a race there's no harm in taking a conservative approach and getting that information again since the directory entry is being reread anyway.

To query mappings for a subrange of the device, the starting byte of the range is written to fsmap_head.fmh_keys[0].fmr_physical and the last byte of the range goes in fsmap_head.fmh_keys[1].fmr_physical. IOWs, to query what mappings overlap with bytes 3-14 of /dev/sda, you'd set the inputs as follows: fmh_keys[0] = { .fmr_device = major(8, 0), .fmr_physical = 3}, fmh_keys[1] = { .fmr_device = major(8, 0), .fmr_physical = 14}, Which would return you whatever is mapped in the 12 bytes starting at physical offset 3. The crash is due to insufficient range validation of keys[1] in ext4_getfsmap_datadev. On 1k-block filesystems, block 0 is not part of the filesystem, which means that s_first_data_block is nonzero. ext4_get_group_no_and_offset subtracts this quantity from the blocknr argument before cracking it into a group number and a block number within a group. IOWs, block group 0 spans blocks 1-8192 (1-based) instead of 0-8191 (0-based) like what happens with larger blocksizes. The net result of this encoding is that blocknr < s_first_data_block is not a valid input to this function. The end_fsb variable is set from the keys that are copied from userspace, which means that in the above example, its value is zero. That leads to an underflow here: blocknr = blocknr - le32_to_cpu(es->s_first_data_block); The division then operates on -1: offset = do_div(blocknr, EXT4_BLOCKS_PER_GROUP(sb)) >> EXT4_SB(sb)->s_cluster_bits; Leaving an impossibly large group number (2^32-1) in blocknr. ext4_getfsmap_check_keys checked that keys[0].fmr_physical and keys[1].fmr_physical are in increasing order, but ext4_getfsmap_datadev adjusts keys[0].fmr_physical to be at least s_first_data_block. This implies that we have to check it again after the adjustment, which is the piece that I forgot.

This happens because they set PF_NO_SETAFFINITY as part of their creation, as io-wq organizes workers into groups based on what CPU they are running on. However, this is purely an optimization and not a functional requirement. We can allow setting affinity, and just lazily update our worker to wqe mappings. If a given io-wq thread times out, it normally exits if there's no more work to do. The exception is if it's the last worker available. For the timeout case, check the affinity of the worker against group mask and exit even if it's the last worker. New workers should be created with the right mask and in the right location.

The non WEP key stores can store keys with indexes 0 - BIP_MAX_KEYID, this means that they should be an array with BIP_MAX_KEYID + 1 entries. But some of the arrays where just BIP_MAX_KEYID entries big. While one other array was hardcoded to a size of 6 entries, instead of using the BIP_MAX_KEYID define. 2. The rtw_cfg80211_set_encryption() and wpa_set_encryption() functions index check where checking that the passed in key-index would fit inside both the WEP key store (which only has 4 entries) as well as in the non WEP key stores. This breaks any attempts to set non WEP keys with index 4 or 5. Issue 2. specifically breaks wifi connection with some access points which advertise PMF support. Without this fix connecting to these access points fails with the following wpa_supplicant messages: nl80211: kernel reports: key addition failed wlan0: WPA: Failed to configure IGTK to the driver wlan0: RSN: Failed to configure IGTK wlan0: CTRL-EVENT-DISCONNECTED bssid=... reason=1 locally_generated=1 Fix 1. by using the right size for the key-stores. After this 2. can safely be fixed by checking the right max-index value depending on the used algorithm, fixing wifi not working with some PMF capable APs.

And the keyword in there is 'stable': the current thread pointer never changes as far as a single thread is concerned. Even if when a thread is preempted, or moved to another CPU, or even across an explicit call 'schedule()' that thread will still have the same value for 'current'. It is, after all, the kernel base pointer to thread-local storage. That's why it's stable to begin with, but it's also why it's important enough that we have that special 'this_cpu_read_stable()' access for it. So this is all done very intentionally to allow the compiler to treat 'current' as a value that never visibly changes, so that the compiler can do CSE and combine multiple different 'current' accesses into one. However, there is obviously one very special situation when the currently running thread does actually change: inside the scheduler itself. So the scheduler code paths are special, and do not have a 'current' thread at all. Instead there are _two_ threads: the previous and the next thread - typically called 'prev' and 'next' (or prev_p/next_p) internally. So this is all actually quite straightforward and simple, and not all that complicated. Except for when you then have special code that is run in scheduler context, that code then has to be aware that 'current' isn't really a valid thing. Did you mean 'prev'? Did you mean 'next'? In fact, even if then look at the code, and you use 'current' after the new value has been assigned to the percpu variable, we have explicitly told the compiler that 'current' is magical and always stable. So the compiler is quite free to use an older (or newer) value of 'current', and the actual assignment to the percpu storage is not relevant even if it might look that way. Which is exactly what happened in the resctl code, that blithely used 'current' in '__resctrl_sched_in()' when it really wanted the new process state (as implied by the name: we're scheduling 'into' that new resctl state). And clang would end up just using the old thread pointer value at least in some configurations. This could have happened with gcc too, and purely depends on random compiler details. Clang just seems to have been more aggressive about moving the read of the per-cpu current_task pointer around. The fix is trivial: just make the resctl code adhere to the scheduler rules of using the prev/next thread pointer explicitly, instead of using 'current' in a situation where it just wasn't valid. That same code is then also used outside of the scheduler context (when a thread resctl state is explicitly changed), and then we will just pass in 'current' as that pointer, of course. There is no ambiguity in that case. The fix may be trivial, but noticing and figuring out what went wrong was not. The credit for that goes to Stephane Eranian.

Arınç reports that the GMAC1 attached to port 5 receives corrupted frames, unless port 6 (attached to GMAC0) has been brought up by the driver. This is true regardless of whether port 5 is used as a user port or as a CPU port (carrying DSA tags). Offline debugging (blind for me) which began in the linked thread showed experimentally that the configuration done by the driver for port 6 contains a step which is needed by port 5 as well - the write to CORE_GSWPLL_GRP2 (note that I've no idea as to what it does, apart from the comment "Set core clock into 500Mhz"). Prints put by Arınç show that the reset value of CORE_GSWPLL_GRP2 is RG_GSWPLL_POSDIV_500M(1) | RG_GSWPLL_FBKDIV_500M(40) (0x128), both on the MCM MT7530 from the MT7621 SoC, as well as on the standalone MT7530 from MT7623NI Bananapi BPI-R2. Apparently, port 5 on the standalone MT7530 can work under both values of the register, while on the MT7621 SoC it cannot. The call path that triggers the register write is: mt753x_phylink_mac_config() for port 6 -> mt753x_pad_setup() -> mt7530_pad_clk_setup() so this fully explains the behavior noticed by Arınç, that bringing port 6 up is necessary. The simplest fix for the problem is to extract the register writes which are needed for both port 5 and 6 into a common mt7530_pll_setup() function, which is called at mt7530_setup() time, immediately after switch reset. We can argue that this mirrors the code layout introduced in mt7531_setup() by commit 42bc4fafe359 ("net: mt7531: only do PLL once after the reset"), in that the PLL setup has the exact same positioning, and further work to consolidate the separate setup() functions is not hindered. Testing confirms that: - the slight reordering of writes to MT7530_P6ECR and to CORE_GSWPLL_GRP1 / CORE_GSWPLL_GRP2 introduced by this change does not appear to cause problems for the operation of port 6 on MT7621 and on MT7623 (where port 5 also always worked) - packets sent through port 5 are not corrupted anymore, regardless of whether port 6 is enabled by phylink or not (or even present in the device tree) My algorithm for determining the Fixes: tag is as follows. Testing shows that some logic from mt7530_pad_clk_setup() is needed even for port 5. Prior to commit ca366d6c889b ("net: dsa: mt7530: Convert to PHYLINK API"), a call did exist for all phy_is_pseudo_fixed_link() ports - so port 5 included. That commit replaced it with a temporary "Port 5 is not supported!" comment, and the following commit 38f790a80560 ("net: dsa: mt7530: Add support for port 5") replaced that comment with a configuration procedure in mt7530_setup_port5() which was insufficient for port 5 to work. I'm laying the blame on the patch that claimed support for port 5, although one would have also needed the change from commit c3b8e07909db ("net: dsa: mt7530: setup core clock even in TRGMII mode") for the write to be performed completely independently from port 6's configuration. Thanks go to Arınç for describing the problem, for debugging and for testing.

Issue is that queue_oob() calls maybe_add_creds() which potentially holds a reference on a pid. But skb->destructor is not set (either directly or by calling unix_scm_to_skb()) This means that subsequent kfree_skb() or consume_skb() would leak this reference. In this fix, I chose to fully support scm even for the OOB message.

Also the rtl8xxxu driver supports way more devices, and is a fraction of the overall size, making this a much better overall solution. Thanks to the r8188eu developers and maintainers and reviewers over the years, your work allowed Linux users to use their hardware before the real driver was implemented properly.

Now that all in-tree drivers are converted to the temporary .probe_new() callback, .probe() can be modified to match the desired prototype. Now that .probe() and .probe_new() have the same semantic, they can be defined as members of an anonymous union to save some memory and simplify the core code a bit.

As notifier callbacks, when (un)registering I2C adapters created or destroyed after i2c_dev_init(), 2. As bus iterator callbacks, for registering already existing adapters from i2c_dev_init(), and for cleanup. Unfortunately both use cases expect different return values: the former expects NOTIFY_* return codes, while the latter expects zero or error codes, and aborts in case of error. Hence in case 2, as soon as i2cdev_{at,de}tach_adapter() returns (non-zero) NOTIFY_OK, the bus iterator aborts. This causes (a) only the first already existing adapter to be registered, leading to missing /dev/i2c-* entries, and (b) a failure to unregister all but the first I2C adapter during cleanup. Fix this by introducing separate callbacks for the bus iterator, wrapping the notifier functions, and always returning succes. Any errors inside these callback functions are unlikely to happen, and are fatal anyway.

We have a number of users that take the previous return value of one of the bit scanning functions and subtract one to keep it in "range". But since the scanning functions end up returning up to 'small_cpumask_bits' instead of the tighter 'nr_cpumask_bits', the range really needs to be using that widened form. [ This "previous-1" behavior is also the reason we have all those comments about /* -1 is a legal arg here. */ and separate checks for that being ok. So we could have just made "small_cpumask_bits-1" be a similar special "don't check this" value. Tetsuo Handa even suggested a patch that only does that for cpumask_next(), since that seems to be the only actual case that triggers, but that all makes it even _more_ magical and special. So just relax the check ] One example of this kind of pattern being the 'c_start()' function in arch/x86/kernel/cpu/proc.c, but also duplicated in various forms on other architectures.

This issue has been fixed in newer versions of the fTPM firmware, but it's up to system designers to decide whether to distribute it. This issue has existed for a while, but is more prevalent starting with kernel 6.1 because commit b006c439d58db ("hwrng: core - start hwrng kthread also for untrusted sources") started to use the fTPM for hwrng by default. However, all uses of /dev/hwrng result in unacceptable stuttering. So, simply disable registration of the defective hwrng when detecting these faulty fTPM versions. As this is caused by faulty firmware, it is plausible that such a problem could also be reproduced by other TPM interactions, but this hasn't been shown by any user's testing or reports. It is hypothesized to be triggered more frequently by the use of the RNG because userspace software will fetch random numbers regularly. Intentionally continue to register other TPM functionality so that users that rely upon PCR measurements or any storage of data will still have access to it. If it's found later that another TPM functionality is exacerbating this problem a module parameter it can be turned off entirely and a module parameter can be introduced to allow users who rely upon fTPM functionality to turn it on even though this problem is present.
