Pull fscrypt updates from Eric Biggers: "This release, we add support for inline encryption via the blk-crypto framework which was added in 5.8. Now when an ext4 or f2fs filesystem is mounted with '-o inlinecrypt', the contents of encrypted files will be encrypted/decrypted via blk-crypto, instead of directly using the crypto API. This model allows taking advantage of the inline encryption hardware that is integrated into the UFS or eMMC host controllers on most mobile SoCs. Note that this is just an alternate implementation; the ciphertext written to disk stays the same. (This pull request does *not* include support for direct I/O on encrypted files, which blk-crypto makes possible, since that part is still being discussed.) Besides the above feature update, there are also a few fixes and cleanups, e.g. strengthening some memory barriers that may be too weak. All these patches have been in linux-next with no reported issues. I've also tested them with the fscrypt xfstests, as usual. It's also been tested that the inline encryption support works with the support for Qualcomm and Mediatek inline encryption hardware that will be in the scsi pull request for 5.9. Also, several SoC vendors are already using a previous, functionally equivalent version of these patches" * tag 'fscrypt-for-linus' of git://git.kernel.org/pub/scm/fs/fscrypt/fscrypt: fscrypt: don't load ->i_crypt_info before it's known to be valid fscrypt: document inline encryption support fscrypt: use smp_load_acquire() for ->i_crypt_info fscrypt: use smp_load_acquire() for ->s_master_keys fscrypt: use smp_load_acquire() for fscrypt_prepared_key fscrypt: switch fscrypt_do_sha256() to use the SHA-256 library fscrypt: restrict IV_INO_LBLK_* to AES-256-XTS fscrypt: rename FS_KEY_DERIVATION_NONCE_SIZE fscrypt: add comments that describe the HKDF info strings ext4: add inline encryption support f2fs: add inline encryption support fscrypt: add inline encryption support fs: introduce SB_INLINECRYPT

Pull btrfs updates from David Sterba: "We don't have any big feature updates this time, there are lots of small enhacements or fixes. A highlight perhaps is the parallel fsync performance improvements, numbers below. Regarding the dio/iomap that was reverted last time, the required API changes are likely to land in the upcoming cycle, the btrfs part will be updated afterwards. User visible changes: - new mount option rescue= to group all recovery-related mount options so we don't have many specific options, currently introducing only aliases for existing options, future extensions are in development to allow read-only mount with partially damaged structures: - usebackuproot is an alias for rescue=usebackuproot - nologreplay is an alias for rescue=nologreplay - start deprecation of mount option inode_cache, removal scheduled to v5.11 - removed deprecated mount options alloc_start and subvolrootid - device stats corruption counter gets incremented when a checksum mismatch is found - qgroup information exported in /sys/fs/btrfs/<UUID>/qgroups/<id> using sysfs - add link /sys/fs/btrfs/<UUID>/bdi pointing to the associated backing dev info - FS_INFO ioctl enhancements: - add flags to request/describe newly added items - new item: numeric checksum type and checksum size - new item: generation - new item: metadata_uuid - seed device: with one new read-write device added, print the new device information in /proc/mounts - balance: detect cancellation by Ctrl-C in existing cancellation points Performance improvements: - optimized versions of various helpers on little-endian architectures, where we don't have to do LE/BE conversion from on-disk format - tree-log/fsync optimizations leading to lower max latency reported by dbench, reduced by about 12% - all chunk tree leaves are prefetched at mount time, can improve mount time on large (terabyte-sized) filesystems - speed up parallel fsync of files with reflinked/deduped extents, with jobs 16 to 1024 the throughput gets improved roughly by 50% on average and runtime decreased roughly by 30% on average, notable outlier is 128 jobs with +121.2% on throughput and -54.6% runtime - another speed up of parallel fsync, reduce number of checksum tree lookups and contention, the improvements start to show up with 2 tasks with +20% throughput and -16% runtime up to 64 with +200% throughput and -66% runtime Core: - umount-time qgroup leak checker - qgroups - add a way to unreserve partial range after failure, avoiding some EDQUOT errors - improved flushing logic when EDQUOT is hit - possible EINTR interruption caused by failed reservations after transaction start is better handled and documented - transaction abort errors are unified to EROFS in case it's not the original reason of abort or we don't have other way to determine the reason Fixes: - make truncate succeed on a NOCOW file even if data space is exhausted - fix cancelling balance on filesystem with exhausted metadata space - anon block device: - preallocate anon bdev when subvolume is created to report failure early - shorten time the anon bdev id is allocated - don't allocate anon bdev for internal roots - minor memory leak in ref-verify - refuse invalid combinations of compression and NOCOW file flags - lockdep fixes, updating the device locks - remove obsolete fallback logic for block group profile adjustments when switching from 1 to more devices, causing allocation of unwanted block groups Other cleanups, refactoring, simplifications: - conversions from struct inode to struct btrfs_inode in internal functions - removal of unused struct members" * tag 'for-5.9-tag' of git://git.kernel.org/pub/scm/linux/kernel/git/kdave/linux: (151 commits) btrfs: do not set the full sync flag on the inode during page release btrfs: release old extent maps during page release btrfs: fix race between page release and a fast fsync btrfs: open-code remount flag setting in btrfs_remount btrfs: if we're restriping, use the target restripe profile btrfs: don't adjust bg flags and use default allocation profiles btrfs: fix lockdep splat from btrfs_dump_space_info btrfs: move the chunk_mutex in btrfs_read_chunk_tree btrfs: open device without device_list_mutex btrfs: sysfs: use NOFS for device creation btrfs: return EROFS for BTRFS_FS_STATE_ERROR cases btrfs: document special case error codes for fs errors btrfs: don't WARN if we abort a transaction with EROFS btrfs: reduce contention on log trees when logging checksums btrfs: remove done label in writepage_delalloc btrfs: add comments for btrfs_reserve_flush_enum btrfs: relocation: review the call sites which can be interrupted by signal btrfs: avoid possible signal interruption of btrfs_drop_snapshot() on relocation tree btrfs: relocation: allow signal to cancel balance btrfs: raid56: remove out label in __raid56_parity_recover ...

It turns out that wait_on_page_bit_common() had several problems, ranging from just unfair behavioe due to re-queueing at the end of the wait queue when re-trying, and an outright bug that could result in missed wakeups (but probably never happened in practice). This rewrites the whole logic to avoid both issues, by simply moving the logic to check (and possibly take) the bit lock into the wakeup path instead. That makes everything much more straightforward, and means that we never need to re-queue the wait entry: if we get woken up, we'll be notified through WQ_FLAG_WOKEN, and the wait queue entry will have been removed, and everything will have been done for us.

When vxlan interface is deleted, all fdbs are deleted by vxlan_flush(). vxlan_flush() flushes fdbs but it doesn't delete fdb, which contains all-zeros-mac because it is deleted by vxlan_uninit().

This reverts commit cc1c08ed. Maxim Levitsky reports 'make xconfig' crashes since that commit (https://lkml.org/lkml/2020/7/18/411) Or, the following is simple test code that makes it crash: menu "Menu" config FOO bool "foo" default y menuconfig BAR bool "bar" depends on FOO endmenu Select the Split View mode, and double-click "bar" in the right window, then you will see Segmentation fault. When 'last' is not set for symbolMode, the following code in ConfigList::updateList() calls firstChild(). item = last ? last->nextSibling() : firstChild(); However, the pointer returned by ConfigList::firstChild() does not seem to be compatible with (ConfigItem *), which seems another bug. I'd rather want to reconsider whether hiding the goback icon is the right thing to do. In the following test code, the Split View shows "Menu2" and "Menu3" in the right window. You can descend into "Menu3", but there is no way to ascend back to "Menu2" from "Menu3". menu "Menu1" config FOO bool "foo" default y menu "Menu2" depends on FOO menu "Menu3" config BAZ bool "baz" endmenu endmenu endmenu It is true that the goback button is currently not functional due to yet another bug, but hiding the problem is not the right way to go. Anyway, Segmentation fault is fatal. Revert the offending commit for now, and we should find the right solution.

This reverts commit 5752ff07. It added dead code to ConfigList:ConfigList(). The constructor of ConfigList has the initializer, mode(singleMode). if (mode == symbolMode) setHeaderLabels(QStringList() << "Item" << "Name" << "N" << "M" << "Y" << "Value"); else setHeaderLabels(QStringList() << "Option" << "Name" << "N" << "M" << "Y" << "Value"); ... always takes the else part. The change to ConfigList::updateSelection() is strange too. When you click the split view icon for the first time, the titles in both windows show "Option". After you click something in the right window, the title suddenly changes to "Item". ConfigList::updateSelection() is not the right place to do this, at least. It was not a good idea, I think.

We've added 5 non-merge commits during the last 21 day(s) which contain a total of 5 files changed, 126 insertions(+), 18 deletions(-). The main changes are: 1) Fix a map element leak in HASH_OF_MAPS map type, from Andrii Nakryiko. 2) Fix a NULL pointer dereference in __btf_resolve_helper_id() when no btf_vmlinux is available, from Peilin Ye. 3) Init pos variable in __bpfilter_process_sockopt(), from Christoph Hellwig. 4) Fix a cgroup sockopt verifier test by specifying expected attach type, from Jean-Philippe Brucker. Note that when net gets merged into net-next later on, there is a small merge conflict in kernel/bpf/btf.c between commit 5b801dfb ("bpf: Fix NULL pointer dereference in __btf_resolve_helper_id()") from the bpf tree and commit 138b9a05 ("bpf: Remove btf_id helpers resolving") from the net-next tree. Resolve as follows: remove the old hunk with the __btf_resolve_helper_id() function. Change the btf_resolve_helper_id() so it actually tests for a NULL btf_vmlinux and bails out: int btf_resolve_helper_id(struct bpf_verifier_log *log, const struct bpf_func_proto *fn, int arg) { int id; if (fn->arg_type[arg] != ARG_PTR_TO_BTF_ID || !btf_vmlinux) return -EINVAL; id = fn->btf_id[arg]; if (!id || id > btf_vmlinux->nr_types) return -EINVAL; return id; } Let me know if you run into any others issues (CC'ing Jiri Olsa so he's in the loop with regards to merge conflict resolution). ==================== Signed-off-by: NDavid S.

rds_notify_queue_get() is potentially copying uninitialized kernel stack memory to userspace since the compiler may leave a 4-byte hole at the end of `cmsg`. In 2016 we tried to fix this issue by doing `= { 0 };` on `cmsg`, which unfortunately does not always initialize that 4-byte hole. Fix it by using memset() instead.

When recording with cache-misses and arm_spe_x event, I found that it will just fail without showing any error info if i put cache-misses after 'arm_spe_x' event. [root@localhost 0620]# perf record -e cache-misses \ -e arm_spe_0/ts_enable=1,pct_enable=1,pa_enable=1,load_filter=1,jitter=1,store_filter=1,min_latency=0/ sleep 1 [ perf record: Woken up 1 times to write data ] [ perf record: Captured and wrote 0.067 MB perf.data ] [root@localhost 0620]# [root@localhost 0620]# perf record -e arm_spe_0/ts_enable=1,pct_enable=1,pa_enable=1,load_filter=1,jitter=1,store_filter=1,min_latency=0/ \ -e cache-misses sleep 1 [root@localhost 0620]# The current code can only work if the only event to be traced is an 'arm_spe_x', or if it is the last event to be specified. Otherwise the last event type will be checked against all the arm_spe_pmus[i]->types, none will match and an out of bound 'i' index will be used in arm_spe_recording_init(). We don't support concurrent multiple arm_spe_x events currently, that is checked in arm_spe_recording_options(), and it will show the relevant info. So add the check and record of the first found 'arm_spe_pmu' to fix this issue here.
