2023-03-08x86/resctl: fix scheduler confusion with 'current'Linus Torvalds
The implementation of 'current' on x86 is very intentionally special: it is a very common thing to look up, and it uses 'this_cpu_read_stable()' to get the current thread pointer efficiently from per-cpu storage. 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.

2023-03-08staging: rtl8723bs: Pass correct parameters to cfg80211_get_bss()Hans de Goede
To last 2 parameters to cfg80211_get_bss() should be of the enum ieee80211_bss_type resp. enum ieee80211_privacy types, which WLAN_CAPABILITY_ESS very much is not. Fix both cfg80211_get_bss() calls in ioctl_cfg80211.c to pass the right parameters. Note that the second call was already somewhat fixed by commenting out WLAN_CAPABILITY_ESS and passing in 0 instead. This was still not entirely correct though since that would limit returned BSS-es to ESS type BSS-es with privacy on.

2023-03-08staging: rtl8723bs: Fix key-store index handlingHans de Goede
There are 2 issues with the key-store index handling 1. 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.

2023-03-08io_uring/io-wq: stop setting PF_NO_SETAFFINITY on io-wq workersJens Axboe
Every now and then reports come in that are puzzled on why changing affinity on the io-wq workers fails with EINVAL. 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.

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.

2023-03-07ext4: fix RENAME_WHITEOUT handling for inline directoriesEric Whitney
A significant number of xfstests can cause ext4 to log one or more warning messages when they are run on a test file system where the inline_data feature has been enabled. 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.

2023-03-07ext4: fix cgroup writeback accounting with fs-layer encryptionEric Biggers
When writing a page from an encrypted file that is using filesystem-layer encryption (not inline encryption), ext4 encrypts the pagecache page into a bounce page, then writes the bounce page. 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().

2023-03-08btrfs: fix block group item corruption after inserting new block groupFilipe Manana
We can often end up inserting a block group item, for a new block group, with a wrong value for the used bytes field. 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 (...)

2023-03-07drm/display: Don't block HDR_OUTPUT_METADATA on unknown EOTFHarry Wentland
The EDID of an HDR display defines EOTFs that are supported by the display and can be set in the HDR metadata infoframe. 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.

2023-03-07cpumask: be more careful with 'cpumask_setall()'Linus Torvalds
Commit 596ff4a09b89 ("cpumask: re-introduce constant-sized cpumask optimizations") changed cpumask_setall() to use "bitmap_set()" instead of "bitmap_fill()", because bitmap_fill() would explicitly set all the bits of a constant sized small bitmap, and that's exactly what we don't want: we want to only set bits up to 'nr_cpu_ids', which is what "bitmap_set()" does. 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. But that is not the world we live in. While we dream of that perfect world, this does that manual logic to make it all work out. And this was a very long explanation for a small code change that shouldn't even matter.

2023-03-07block: fix wrong mode for blkdev_put() from disk_scan_partitions()Yu Kuai
If disk_scan_partitions() is called with 'FMODE_EXCL', blkdev_get_by_dev() will be called without 'FMODE_EXCL', however, follow blkdev_put() is still called with 'FMODE_EXCL', which will cause 'bd_holders' counter to leak. Fix the problem by using the right mode for blkdev_put().
