2024-08-24netfs: Fix trimming of streaming-write folios in netfs_inval_folio()David Howells
When netfslib writes to a folio that it doesn't have data for, but that data exists on the server, it will make a 'streaming write' whereby it stores data in a folio that is marked dirty, but not uptodate. When it does this, it attaches a record to folio->private to track the dirty region. When truncate() or fallocate() wants to invalidate part of such a folio, it will call into ->invalidate_folio(), specifying the part of the folio that is to be invalidated. netfs_invalidate_folio(), on behalf of the filesystem, must then determine how to trim the streaming write record. In a couple of cases, however, it does this incorrectly (the reduce-length and move-start cases are switched over and don't, in any case, calculate the value correctly). Fix this by making the logic tree more obvious and fixing the cases.

2024-08-24netfs: Fix netfs_release_folio() to say no if folio dirtyDavid Howells
Fix netfs_release_folio() to say no (ie. return false) if the folio is dirty (analogous with iomap's behaviour). Without this, it will say yes to the release of a dirty page by split_huge_page_to_list_to_order(), which will result in the loss of untruncated data in the folio. Without this, the generic/075 and generic/112 xfstests (both fsx-based tests) fail with minimum folio size patches applied[1].

2024-08-24afs: Fix post-setattr file edit to do truncation correctlyDavid Howells
At the end of an kAFS RPC operation, there is an "edit" phase (originally intended for post-directory modification ops to edit the local image) that the setattr VFS op uses to fix up the pagecache if the RPC that requested truncation of a file was successful. afs_setattr_edit_file() calls truncate_setsize() which sets i_size, expands the pagecache if needed and truncates the pagecache. The first two of those, however, are redundant as they've already been done by afs_setattr_success() under the io_lock and the first is also done under the callback lock (cb_lock). Fix afs_setattr_edit_file() to call truncate_pagecache() instead (which is called by truncate_setsize(), thereby skipping the redundant parts.

2024-08-24mm: Fix missing folio invalidation calls during truncationDavid Howells
When AS_RELEASE_ALWAYS is set on a mapping, the ->release_folio() and ->invalidate_folio() calls should be invoked even if PG_private and PG_private_2 aren't set. This is used by netfslib to keep track of the point above which reads can be skipped in favour of just zeroing pagecache locally. There are a couple of places in truncation in which invalidation is only called when folio_has_private() is true. Fix these to check folio_needs_release() instead. Without this, the generic/075 and generic/112 xfstests (both fsx-based tests) fail with minimum folio size patches applied[1].

2024-08-23ovl: fix wrong lowerdir number check for parameter Opt_lowerdirZhihao Cheng
The max count of lowerdir is OVL_MAX_STACK[500], which is broken by commit 37f32f526438("ovl: fix memory leak in ovl_parse_param()") for parameter Opt_lowerdir. Since commit 819829f0319a("ovl: refactor layer parsing helpers") and commit 24e16e385f22("ovl: add support for appending lowerdirs one by one") added check ovl_mount_dir_check() in function ovl_parse_param_lowerdir(), the 'ctx->nr' should be smaller than OVL_MAX_STACK, after commit 37f32f526438("ovl: fix memory leak in ovl_parse_param()") is applied, the 'ctx->nr' is updated before the check ovl_mount_dir_check(), which leads the max count of lowerdir to become 499 for parameter Opt_lowerdir. Fix it by replacing lower layers parsing code with the existing helper function ovl_parse_layer().

2024-08-18fuse: Initialize beyond-EOF page contents before setting uptodateJann Horn
fuse_notify_store(), unlike fuse_do_readpage(), does not enable page zeroing (because it can be used to change partial page contents). So fuse_notify_store() must be more careful to fully initialize page contents (including parts of the page that are beyond end-of-file) before marking the page uptodate. The current code can leave beyond-EOF page contents uninitialized, which makes these uninitialized page contents visible to userspace via mmap(). This is an information leak, but only affects systems which do not enable init-on-alloc (via CONFIG_INIT_ON_ALLOC_DEFAULT_ON=y or the corresponding kernel command line parameter).

2024-08-16btrfs: only enable extent map shrinker for DEBUG buildsQu Wenruo
Although there are several patches improving the extent map shrinker, there are still reports of too frequent shrinker behavior, taking too much CPU for the kswapd process. So let's only enable extent shrinker for now, until we got more comprehensive understanding and a better solution.
