RISC-V Patches for the 5.19 Merge Window, Part 1
* Support for the Svpbmt extension, which allows memory attributes to be encoded in pages. * Support for the Allwinner D1's implementation of page-based memory attributes. * Support for running rv32 binaries on rv64 systems, via the compat subsystem. * Support for kexec_file(). * Support for the new generic ticket-based spinlocks, which allows us to also move to qrwlock. These should have already gone in through the asm-geneic tree as well. * A handful of cleanups and fixes, include some larger ones around atomics and XIP. -----BEGIN PGP SIGNATURE----- iQJHBAABCAAxFiEEKzw3R0RoQ7JKlDp6LhMZ81+7GIkFAmKWOx8THHBhbG1lckBk YWJiZWx0LmNvbQAKCRAuExnzX7sYieAiEADAUdP7ctoaSQwk5skd/fdA3b4KJuKn 1Zjl+Br32WP0DlbirYBYWRUQZnCCsvABbTiwSJMcG7NBpU5pyQ5XDtB3OA5kJswO Fdp8Nd53//+GK1M5zdEM9OdgvT9fbfTZ3qTu8bKsROOQhGwnYL+Csc9KjFRqEmzN oQii0jlb3n5PM4FL3GsbV4uMn9zzkP9mnVAPQktcock2EKFEK/Fy3uNYMQiO2KPi n8O6bIDaeRdQ6SurzWOuOkt0cro0tEF85ilzT04mynQsOU0el5oGqCxnOhNH3VWg ndqPT6Yafw12hZOtbKJeP+nF8IIR6aJLP3jOtRwEVgcfbXYAw4QwbAV8kQZISefN ipn8JGY7GX9Y9TYU692OUGkcmAb3/dxb6c0WihBdvJ0M6YyLD5X+YKHNuG2onLgK ss43C5Mxsu629rsjdu/PV91B1+pve3rG9siVmF+g4eo0x9rjMq6/JB0Kal/8SLI1 Je5T55d5ujV1a2XxhZLQOSD5owrK7J1M9owb0bloTnr9nVwFTWDrfEQEU82o3kP+ Xm+FfXktnz9ai55NjkMbbEur5D++dKJhBavwCTnBcTrJmMtEH0R45GTK9ZehP+WC rNVrRXjIsS18wsTfJxnkZeFQA38as6VBKTzvwHvOgzTrrZU1/xk3lpkouYtAO6BG gKacHshVilmUuA== =Loi6 -----END PGP SIGNATURE----- Merge tag 'riscv-for-linus-5.19-mw0' of git://git.kernel.org/pub/scm/linux/kernel/git/riscv/linux Pull RISC-V updates from Palmer Dabbelt: - Support for the Svpbmt extension, which allows memory attributes to be encoded in pages - Support for the Allwinner D1's implementation of page-based memory attributes - Support for running rv32 binaries on rv64 systems, via the compat subsystem - Support for kexec_file() - Support for the new generic ticket-based spinlocks, which allows us to also move to qrwlock.

pipe: Fix missing lock in pipe_resize_ring()
pipe_resize_ring() needs to take the pipe->rd_wait.lock spinlock to
prevent post_one_notification() from trying to insert into the ring
whilst the ring is being replaced.
The occupancy check must be done after the lock is taken, and the lock
must be taken after the new ring is allocated.
The bug can lead to an oops looking something like:
BUG: KASAN: use-after-free in post_one_notification.isra.0+0x62e/0x840

NFSD 5.19 Release Notes
We introduce "courteous server" in this release. Previously NFSD would purge open and lock state for an unresponsive client after one lease period (typically 90 seconds). Now, after one lease period, another client can open and lock those files and the unresponsive client's lease is purged; otherwise if the unrespon- sive client's open and lock state is uncontended, the server retains that open and lock state for up to 24 hours, allowing the client's workload to resume after a lengthy network partition. A longstanding issue with NFSv4 file creation is also addressed. Previously a file creation can fail internally, returning an error to the client, but leave the newly created file in place as an artifact. The file creation code path has been reorganized so that internal failures and race conditions are less likely to result in an unwanted file creation. A fault injector has been added to help exercise paths that are run during kernel metadata cache invalidation. These caches contain information maintained by user space about exported filesystems. Many of our test workloads do not trigger cache invalidation. There is one patch that is needed to support PREEMPT_RT and a fix for an ancient "sleep while spin-locked" splat that seems to have become easier to hit since v5.18-rc3. -----BEGIN PGP SIGNATURE----- iQIzBAABCAAdFiEEKLLlsBKG3yQ88j7+M2qzM29mf5cFAmKPliAACgkQM2qzM29m f5dB3BAAorPa2L8xu5P1Ge1oTNogNSOVRkLPDzEkfEwK07ZM2qvz78eMZGkMziJ/ strorvBWl3SWBlVtTePgNpJUjgYQ75MRRwaX7Qh2WuHeRKm1JlZm0/NId3+zKgbh N40QI20jdswWcNDuhidxVFFWurd09GlcM4z1cu8gZLbfthkiUOjZoPiLkXeNcvhk 7wC9GiueWxHefYQQDAKh1nQS/L0GG1EkzJdJo7WUVAldZ9qVY9LpmJVMRqrBBbta XrFYfpeY1zFFDY4Qolyz5PUJSeQuDj9PctlhoZ6B1hp56PD/6yaqVhYXiPxtlALj tITtktfiekULZkgfvfvyzssCv+wkbYiaEBZcSSCauR7dkGOmBmajO+cf7vpsERgE fbCU8DWGk78SMeehdCrO+26cV37VP+8c2t2Txq/rG5Eq4ZoCi++Hj5poRboFLqb+ oom+0Ee0LfcAKXkxH5gWTPTblHo49GzGitPZtRzTgZ9uFnVwvEaJ4+t0ij0J8JpL HuVtWrg5/REhqpEvOSwF0sRmkYWLTu7KdueGn/iZ8xUi7GHEue01NsVkClohKJcR WOjWrbNCNF/LJaG88MX0z5u7IO7s9bOHphd7PJ92vR+4YsehW3uRhk+rNi2ZBqQz hzULfu8BiaicV9fdB/hDcMmKQD6U6due2AVVPtxTf5XY+CHQNRY= =phE1 -----END PGP SIGNATURE----- Merge tag 'nfsd-5.19' of git://git.kernel.org/pub/scm/linux/kernel/git/cel/linux Pull nfsd updates from Chuck Lever: "We introduce 'courteous server' in this release.

sysctl changes for v5.19-rc1
For two kernel releases now kernel/sysctl.c has been being cleaned up slowly, since the tables were grossly long, sprinkled with tons of #ifdefs and all this caused merge conflicts with one susbystem or another. This tree was put together to help try to avoid conflicts with these cleanups going on different trees at time. So nothing exciting on this pull request, just cleanups. I actually had this sysctl-next tree up since v5.18 but I missed sending a pull request for it on time during the last merge window. And so these changes have been being soaking up on sysctl-next and so linux-next for a while. The last change was merged May 4th. Most of the compile issues were reported by 0day and fixed. To help avoid a conflict with bpf folks at Daniel Borkmann's request I merged bpf-next/pr/bpf-sysctl into sysctl-next to get the effor which moves the BPF sysctls from kernel/sysctl.c to BPF core.

NFSD: Fix possible sleep during nfsd4_release_lockowner()
nfsd4_release_lockowner() holds clp->cl_lock when it calls check_for_locks(). However, check_for_locks() calls nfsd_file_get() / nfsd_file_put() to access the backing inode's flc_posix list, and nfsd_file_put() can sleep if the inode was recently removed. Let's instead rely on the stateowner's reference count to gate whether the release is permitted. This should be a reliable indication of locks-in-use since file lock operations and ->lm_get_owner take appropriate references, which are released appropriately when file locks are removed.

xfs: Changes for 5.19-rc1
This update includes: - support for printk message indexing. - large extent counts to provide support for up to 2^47 data extents and 2^32 attribute extents, allowing us to scale beyond 4 billion data extents to billions of xattrs per inode. - conversion of various flags fields to be consistently declared as unsigned bit fields. - improvements to realtime extent accounting and converts them to per-cpu counters to match all the other block and inode accounting. - reworks core log formatting code to reduce iterations, have a shorter, cleaner fast path and generally be easier to understand and maintain. - improvements to rmap btree searches that reduce overhead by up to 30% resulting in xfs_scrub runtime reductions of 15%. - improvements to reflink that remove the size limitations in remapping operations and greatly reduce the size of transaction reservations. - reworks the minimum log size calculations to allow us to change transaction reservations without changing the minimum supported log size. - removal of quota warning support as it has never been used on Linux. - intent whiteouts to allow us to cancel intents that are completed entirely in memory rather than having use CPU and disk bandwidth formatting and writing them into the journal when it is not necessary. This makes rmap, reflink and extent freeing slightly more efficient, but provides massive improvements for.... - Logged Attribute Replay feature support. This is a fundamental change to the way we modify attributes, laying the foundation for future integration of attribute modifications as part of other atomic transactional operations the filesystem performs. - Lots of cleanups and fixes for the logged attribute replay functionality. -----BEGIN PGP SIGNATURE----- iQJIBAABCgAyFiEEmJOoJ8GffZYWSjj/regpR/R1+h0FAmKO2lIUHGRhdmlkQGZy b21vcmJpdC5jb20ACgkQregpR/R1+h0cYRAAutdpA5BZzfgpqnRbmjkOzCmhp6xj mSB6A8iBvlhtfY8p0IFFSbTT6jnf+EWfnsjy/jopojhhz5vCqYKfhGM6P9KBHxfz amxfmWZd3XWcnc8Ay9hcjLIa7QLQr8PXh3zJhjiYm8PvsrtNzsiEKrh6lxG6pe0w vQiq062ColCdN5DcuFVtfScsynCrzZCbUWFGm3y27NF00JpLdm8aBO57/ZaSFVdA UKKsogoPUNkRIbmf81IjTWTx2f0syNQyjrK+CX0sxGb6nzcoU/dT8qQ5t/U5gPTc cGpHE6vyBLdNA6BlnrFBoVAQ/M8n+ixnYy7XytZuTL5Izo80N+Vo+U5d1nLvC+fn ZLKAxbtpudqjy2O393Nv0cqEkT/xPUy2x3IvNL1rKXlQmNWt+KFGuiNrE+y2W4WT 1bfbnmUJi0Knde4MD43iImwwaocXXdtVkED9f68aknZLCihqGEoi1EmU1Sr4+Wbj D8lXZe4BZfGVCHoA2sDtgJsATAG5rdBu/Y6lJcEfUSblvwF2Ufh0r9ehieDrnGmq asCTuXmIX/AzUQDa7JjgAzo2sgdhI+nOIPWJeKDVHRdpFjq+7xV573Iqa77Brik9 DNxAMATh5bZc+9paDib8Za55yE7NJO1cM/UJkwwqn3rvbV5hYki0XZvlKZQsJGig ur5otF9Sdz+AcmE= =yUEM -----END PGP SIGNATURE----- Merge tag 'xfs-5.19-for-linus' of git://git.kernel.org/pub/scm/fs/xfs/xfs-linux Pull xfs updates from Dave Chinner: "This is a big update with lots of new code. The summary below them all, so I'll just touch on teh higlights. The two main new features are Large Extent Counts and Logged Attribute Replay - these are two new foundational features that we are building more complex future features on top of. For upcoming functionality, we need to be able to store hundreds of millions of xattrs per inode. The Large Extent Count feature removes the limits that prevent this scale of xattr storage, and while we were modifying the on disk extent count format we also increased the number of data extents we support per inode from 2^32 to 2^47. We also need to be able to modify xattrs as part of larger atomic transactions rather than as standalone transactions. The Logged Attribute Replay feature introduces the infrastructure that allows us to use intents to record the attribute modifications in the journal before we start them, hence allowing other atomic transactions to log attribute modification intents and then defer the actual modification to later. If we then crash, log recovery then guarantees that the attribute is replayed in the context of the atomic transaction that logged the intent. A significant chunk of the commits in this merge are for the base attribute replay functionality along with fixes, improvements and cleanups related to this new functioanlity. Allison deserves a big round of thanks for her ongoing work to get this functionality into XFS. There are also many other smaller changes and improvements, so overall this is one of the bigger XFS merge requests in some time. I will be following up next week with another smaller pull request - we already have another round of fixes and improvements to the logged attribute replay functionality just about ready to go. They'll soak and test over the next week, and I'll send a pull request for them near the end of the merge window.

ocfs2: dlmfs: fix error handling of user_dlm_destroy_lock
When user_dlm_destroy_lock failed, it didn't clean up the flags it set before exit. For USER_LOCK_IN_TEARDOWN, if this function fails because of lock is still in used, next time when unlink invokes this function, it will return succeed, and then unlink will remove inode and dentry if lock is not in used(file closed), but the dlm lock is still linked in dlm lock resource, then when bast come in, it will trigger a panic due to user-after-free. See the following panic call trace. To fix this, USER_LOCK_IN_TEARDOWN should be reverted if fail. And also error should be returned if USER_LOCK_IN_TEARDOWN is set to let user know that unlink fail. For the case of ocfs2_dlm_unlock failure, besides USER_LOCK_IN_TEARDOWN, USER_LOCK_BUSY is also required to be cleared. Even though spin lock is released in between, but USER_LOCK_IN_TEARDOWN is still set, for USER_LOCK_BUSY, if before every place that waits on this flag, USER_LOCK_IN_TEARDOWN is checked to bail out, that will make sure no flow waits on the busy flag set by user_dlm_destroy_lock(), then we can simplely revert USER_LOCK_BUSY when ocfs2_dlm_unlock fails. Fix user_dlm_cluster_lock() which is the only function not following this.

ocfs2: dlmfs: don't clear USER_LOCK_ATTACHED when destroying lock
The following function is the only place that checks USER_LOCK_ATTACHED. This flag is set when lock request is granted through user_ast() and only the following function will clear it. Checking of this flag here is to make sure ocfs2_dlm_unlock is not issued if this lock is never granted. For example, lock file is created and then get removed, open file never happens. Clearing the flag here is not necessary because this is the only function that checks it, if another flow is executing user_dlm_destroy_lock(), it will bail out at the beginning because of USER_LOCK_IN_TEARDOWN and never check USER_LOCK_ATTACHED. Drop the clear, so we don't need take care of it for the following error handling patch. int user_dlm_destroy_lock(struct user_lock_res *lockres) { ... status = 0; if (!(lockres->l_flags & USER_LOCK_ATTACHED)) { spin_unlock(&lockres->l_lock); goto bail; } lockres->l_flags &= ~USER_LOCK_ATTACHED; lockres->l_flags |= USER_LOCK_BUSY; spin_unlock(&lockres->l_lock); status = ocfs2_dlm_unlock(conn, &lockres->l_lksb, DLM_LKF_VALBLK); if (status) { user_log_dlm_error("ocfs2_dlm_unlock", status, lockres); goto bail; } ... } V1 discussion with Joseph: https://lore.kernel.org/all/7b620c53-0c45-da2c-829e-26195cbe7d4e@linux.alibaba.com/T/ Link: https://lkml.kernel.org/r/20220518235224.87100-1-junxiao.bi@oracle.com Signed-off-by: Junxiao Bi <junxiao.bi@oracle.com> Reviewed-by: Joseph Qi <joseph.qi@linux.alibaba.com> Cc: Mark Fasheh <mark@fasheh.com> Cc: Joel Becker <jlbec@evilplan.org> Cc: Junxiao Bi <junxiao.bi@oracle.com> Cc: Changwei Ge <gechangwei@live.cn> Cc: Gang He <ghe@suse.com> Cc: Jun Piao <piaojun@huawei.com> Signed-off-by: Andrew Morton <akpm@linux-foundation.org> |

Networking changes for 5.19.
Core ---- - Support TCPv6 segmentation offload with super-segments larger than 64k bytes using the IPv6 Jumbogram extension header (AKA BIG TCP). - Generalize skb freeing deferral to per-cpu lists, instead of per-socket lists. - Add a netdev statistic for packets dropped due to L2 address mismatch (rx_otherhost_dropped). - Continue work annotating skb drop reasons. - Accept alternative netdev names (ALT_IFNAME) in more netlink requests. - Add VLAN support for AF_PACKET SOCK_RAW GSO. - Allow receiving skb mark from the socket as a cmsg. - Enable memcg accounting for veth queues, sysctl tables and IPv6. BPF --- - Add libbpf support for User Statically-Defined Tracing (USDTs). - Speed up symbol resolution for kprobes multi-link attachments. - Support storing typed pointers to referenced and unreferenced objects in BPF maps. - Add support for BPF link iterator. - Introduce access to remote CPU map elements in BPF per-cpu map. - Allow middle-of-the-road settings for the kernel.unprivileged_bpf_disabled sysctl. - Implement basic types of dynamic pointers e.g. to allow for dynamically sized ringbuf reservations without extra memory copies. Protocols --------- - Retire port only listening_hash table, add a second bind table hashed by port and address. Avoid linear list walk when binding to very popular ports (e.g. 443). - Add bridge FDB bulk flush filtering support allowing user space to remove all FDB entries matching a condition. - Introduce accept_unsolicited_na sysctl for IPv6 to implement router-side changes for RFC9131. - Support for MPTCP path manager in user space. - Add MPTCP support for fallback to regular TCP for connections that have never connected additional subflows or transmitted out-of-sequence data (partial support for RFC8684 fallback). - Avoid races in MPTCP-level window tracking, stabilize and improve throughput. - Support lockless operation of GRE tunnels with seq numbers enabled. - WiFi support for host based BSS color collision detection. - Add support for SO_TXTIME/SCM_TXTIME on CAN sockets. - Support transmission w/o flow control in CAN ISOTP (ISO 15765-2). - Support zero-copy Tx with TLS 1.2 crypto offload (sendfile). - Allow matching on the number of VLAN tags via tc-flower. - Add tracepoint for tcp_set_ca_state().

cifs: fix ntlmssp on old servers
Some older servers seem to require the workstation name during ntlmssp
to be at most 15 chars (RFC1001 name length), so truncate it before
sending when using insecure dialects.

The biggest change this time around is that writeback errors longer clear pageuptodate nor does XFS invalidate the page cache anymore. This brings XFS (and gfs2/zonefs) behavior in line with every other Linux filesystem driver, and fixes some UAF bugs that only cropped up after willy turned on multipage folios for XFS in 5.18-rc1. Regrettably, it took all the way to the end of the 5.18 cycle to find the source of these bugs and reach a consensus that XFS' writeback failure behavior from 20 years ago is no longer necessary.

Hopefully it could bring more possibility to the communities. The story mainly started from a new project what we called "RAFS v6" [1] for Nydus image service almost a year ago, which enhances EROFS to be a new form of one bootstrap (which includes metadata representing the whole fs tree) + several data-deduplicated content addressable blobs (actually treated as multiple devices). Each blob can represent one container image layer but not quite exactly since all new data can be fully existed in the previous blobs so no need to introduce another new blob. It is actually not a new idea (at least on my side it's much like a simpilied casync [2] for now) and has many benefits over per-file blobs or some other exist ways since typically each RAFS v6 image only has dozens of device blobs instead of thousands of per-file blobs. It's easy to be signed with user keys as a golden image, transfered untouchedly with minimal overhead over the network, kept in some type of storage conveniently, and run with (optional) runtime verification but without involving too many irrelevant features crossing the system beyond EROFS itself. At least it's our final goal and we're keeping working on it. There was also a good summary of this approach from the casync author [3]. Regardless further optimizations, this work is almost done in the previous Linux release cycles. In this round, we'd like to introduce on-demand load for EROFS with the fscache/cachefiles infrastructure, considering the following advantages: - Introduce new file-based backend to EROFS. Although each image only contains dozens of blobs but in densely-deployed runC host for example, there could still be massive blobs on a machine, which is messy if each blob is treated as a device. In contrast, fscache and cachefiles are really great interfaces for us to make them work. - Introduce on-demand load to fscache and EROFS. Previously, fscache is mainly used to caching network-likewise filesystems, now it can support on-demand downloading for local fses too with the exact localfs on-disk format. It has many advantages which we're been described in the latest patchset cover letter [4]. In addition to that, most importantly, the cached data is still stored in the original local fs on-disk format so that it's still the one signed with private keys but only could be partially available. Users can fully trust it during running. Later, users can also back up cachefiles easily to another machine. - More reliable on-demand approach in principle. After data is all available locally, user daemon can be no longer online in some use cases, which helps daemon crash recovery (filesystems can still in service) and hot-upgrade (user daemon can be upgraded more frequently due to new features or protocols introduced.) - Other format can also be converted to EROFS filesystem format over the internet on the fly with the new on-demand load feature and mounted. That is entirely possible with on-demand load feature as long as such archive format metadata can be fetched in advance like stargz. In addition, although currently our target user is Nydus image service [5], but laterly, it can be used for other use cases like on-demand system booting, etc. As for the fscache on-demand load feature itself, strictly it can be used for other local fses too. Laterly we could promote most code to the iomap infrastructure and also enhance it in the read-write way if other local fses are interested. Thanks David Howells for taking so much time and patience on this these months, many thanks with great respect here again! Thanks Jeffle for working on this feature and Xin Yin from Bytedance for asynchronous I/O implementation as well as Zichen Tian, Jia Zhu, and Yan Song for testing, much appeciated. We're also exploring more possibly over fscache cache management over FSDAX for secure containers and working on more improvements and useful features for fscache, cachefiles, and on-demand load. In addition to "erofs over fscache", NFS export and idmapped mount are also completed in this cycle for container use cases as well.

This is similar to turning a mount ro with the difference that in contrast to turning a mount ro changing the idmapping can only ever be done once while a mount can transition between ro and rw as much as it wants. The vfs layer itself takes care to retrieve the idmapping of a mount once ensuring that the idmapping used for vfs permission checking is identical to the idmapping passed down to the filesystem. All filesystems with FS_ALLOW_IDMAP raised take the same precautions as the vfs in code-paths that are outside of direct control of the vfs such as ioctl()s. However, holding writers makes this more robust and predictable for both the kernel and userspace. This is a minor user-visible change. But it is extremely unlikely to matter. The caller must've created a detached mount via OPEN_TREE_CLONE and then handed that O_PATH fd to another process or thread which then must've gotten a writable fd for that mount and started creating files in there while the caller is still changing mount properties. While not impossible it will be an extremely rare corner-case and should in general be considered a bug in the application. Consider making a mount MOUNT_ATTR_NOEXEC or MOUNT_ATTR_NODEV while allowing someone else to perform lookups or exec'ing in parallel by handing them a copy of the OPEN_TREE_CLONE fd or another fd beneath that mount. I've pinged all major users of idmapped mounts pointing out this change and none of them have active writers on a mount while still changing mount properties. It would've been strange if they did. The rest and majority of the work will be coming through the overlayfs tree this cycle. In addition to overlayfs this cycle should also see support for idmapped mounts on erofs as I've acked a patch to this effect a little while ago" * tag 'fs.idmapped.v5.19' of git://git.kernel.org/pub/scm/linux/kernel/git/brauner/linux: fs: hold writers when changing mount's idmapping docs: Add small intro to idmap examples |

ext4: only allow test_dummy_encryption when supported
Make the test_dummy_encryption mount option require that the encrypt feature flag be already enabled on the filesystem, rather than automatically enabling it. Practically, this means that "-O encrypt" will need to be included in MKFS_OPTIONS when running xfstests with the test_dummy_encryption mount option. (ext4/053 also needs an update.) Moreover, as long as the preconditions for test_dummy_encryption are being tightened anyway, take the opportunity to start rejecting it when !CONFIG_FS_ENCRYPTION rather than ignoring it. The motivation for requiring the encrypt feature flag is that: - Having the filesystem auto-enable feature flags is problematic, as it bypasses the usual sanity checks. The specific issue which came up recently is that in kernel versions where ext4 supports casefold but not encrypt+casefold (v5.1 through v5.10), the kernel will happily add the encrypt flag to a filesystem that has the casefold flag, making it unmountable -- but only for subsequent mounts, not the initial one. This confused the casefold support detection in xfstests, causing generic/556 to fail rather than be skipped. - The xfstests-bld test runners (kvm-xfstests et al.) already use the required mkfs flag, so they will not be affected by this change. Only users of test_dummy_encryption alone will be affected. But, this option has always been for testing only, so it should be fine to require that the few users of this option update their test scripts. - f2fs already requires it (for its equivalent feature flag).

This was intended to skip the check on the first extent, but

so even though lblock<=prev, the function does not return an error.
As a result, bug_ON occurs in __es_tree_search and the system panics.
To solve this problem, we only need to check that:
1. The lblock of the first extent is not less than 0.
2. The lblock of the next extent is not less than
the next block of the previous extent.
The same applies to extent_idx.

ext4: avoid cycles in directory h-tree
A maliciously corrupted filesystem can contain cycles in the h-tree stored inside a directory. That can easily lead to the kernel corrupting tree nodes that were already verified under its hands while doing a node split and consequently accessing unallocated memory. Fix the problem by verifying traversed block numbers are unique.

ext4: verify dir block before splitting it
Before splitting a directory block verify its directory entries are sane so that the splitting code does not access memory it should not.

ext4: filter out EXT4_FC_REPLAY from on-disk superblock field s_state
The EXT4_FC_REPLAY bit in sbi->s_mount_state is used to indicate that we are in the middle of replay the fast commit journal. This was actually a mistake, since the sbi->s_mount_info is initialized from es->s_state. Arguably s_mount_state is misleadingly named, but the name is historical --- s_mount_state and s_state dates back to ext2. What should have been used is the ext4_{set,clear,test}_mount_flag() inline functions, which sets EXT4_MF_* bits in sbi->s_mount_flags. The problem with using EXT4_FC_REPLAY is that a maliciously corrupted superblock could result in EXT4_FC_REPLAY getting set in s_mount_state. This bypasses some sanity checks, and this can trigger a BUG() in ext4_es_cache_extent(). As a easy-to-backport-fix, filter out the EXT4_FC_REPLAY bit for now. We should eventually transition away from EXT4_FC_REPLAY to something like EXT4_MF_REPLAY.

gfs2: Convert function bh_get to use iomap
Before this patch, function bh_get used block_map to figure out the block it needed to read in from the quota_change file. This patch changes it to use iomap directly to make it more efficient.

gfs2: use i_lock spin_lock for inode qadata
Before this patch, functions gfs2_qa_get and _put used the i_rw_mutex to prevent simultaneous access to its i_qadata. But i_rw_mutex is now used for many other things, including iomap_begin and end, which causes a conflict according to lockdep. We cannot just remove the lock since simultaneous opens (gfs2_open -> gfs2_open_common -> gfs2_qa_get) can then stomp on each others values for i_qadata. This patch solves the conflict by using the i_lock spin_lock in the inode to prevent simultaneous access.

gfs2: Use container_of() for gfs2_glock(aspace)
Clang's structure layout randomization feature gets upset when it sees struct address_space (which is randomized) cast to struct gfs2_glock. This is due to seeing the mapping pointer as being treated as an array of gfs2_glock, rather than "something else, before struct address_space": In file included from fs/gfs2/acl.c:23: fs/gfs2/meta_io.h:44:12: error: casting from randomized structure pointer type 'struct address_space *' to 'struct gfs2_glock *' return (((struct gfs2_glock *)mapping) - 1)->gl_name.ln_sbd; ^ Replace the instances of open-coded pointer math with container_of() usage, and update the allocator to match.
