Merge tag 'fs.idmapped.overlay.acl.v5.20' of git://git.kernel.org/pub/scm/linux/kernel/git/brauner/linux Pull acl updates from Christian Brauner: "Last cycle we introduced support for mounting overlayfs on top of idmapped mounts. While looking into additional testing we realized that posix acls don't really work correctly with stacking filesystems on top of idmapped layers. We already knew what the fix were but it would require work that is more suitable for the merge window so we turned off posix acls for v5.19 for overlayfs on top of idmapped layers with Miklos routing my patch upstream in 72a8e05d ("Merge tag 'ovl-fixes-5.19-rc7' [..]"). This contains the work to support posix acls for overlayfs on top of idmapped layers. Since the posix acl fixes should use the new vfs{g,u}id_t work the associated branch has been merged in. (We sent a pull request for this earlier.) We've also pulled in Miklos pull request containing my patch to turn of posix acls on top of idmapped layers. This allowed us to avoid rebasing the branch which we didn't like because we were already at rc7 by then. Merging it in allows this branch to first fix posix acls and then to cleanly revert the temporary fix it brought in by commit 4a47c638 ("ovl: turn of SB_POSIXACL with idmapped layers temporarily"). The last patch in this series adds Seth Forshee as a co-maintainer for idmapped mounts. Seth has been integral to all of this work and is also the main architect behind the filesystem idmapping work which ultimately made filesystems such as FUSE and overlayfs available in containers. He continues to be active in both development and review. I'm very happy he decided to help and he has my full trust. This increases the bus factor which is always great for work like this. I'm honestly very excited about this because I think in general we don't do great in the bringing on new maintainers department" For more explanations of the ACL issues, see https://lore.kernel.org/all/20220801145520.1532837-1-brauner@kernel.org/ * tag 'fs.idmapped.overlay.acl.v5.20' of git://git.kernel.org/pub/scm/linux/kernel/git/brauner/linux: Add Seth Forshee as co-maintainer for idmapped mounts Revert "ovl: turn of SB_POSIXACL with idmapped layers temporarily" ovl: handle idmappings in ovl_get_acl() acl: make posix_acl_clone() available to overlayfs acl: port to vfs{g,u}id_t acl: move idmapped mount fixup into vfs_{g,s}etxattr() mnt_idmapping: add vfs[g,u]id_into_k[g,u]id()

Pull fs idmapping updates from Christian Brauner: "This introduces the new vfs{g,u}id_t types we agreed on. Similar to k{g,u}id_t the new types are just simple wrapper structs around regular {g,u}id_t types. They allow to establish a type safety boundary in the VFS for idmapped mounts preventing confusion betwen {g,u}ids mapped into an idmapped mount and {g,u}ids mapped into the caller's or the filesystem's idmapping. An initial set of helpers is introduced that allows to operate on vfs{g,u}id_t types. We will remove all references to non-type safe idmapped mounts helpers in the very near future. The patches do already exist. This converts the core attribute changing codepaths which become significantly easier to reason about because of this change. Just a few highlights here as the patches give detailed overviews of what is happening in the commit messages: - The kernel internal struct iattr contains type safe vfs{g,u}id_t values clearly communicating that these values have to take a given mount's idmapping into account. - The ownership values placed in struct iattr to change ownership are identical for idmapped and non-idmapped mounts going forward. This also allows to simplify stacking filesystems such as overlayfs that change attributes In other words, they always represent the values. - Instead of open coding checks for whether ownership changes have been requested and an actual update of the inode is required we now have small static inline wrappers that abstract this logic away removing a lot of code duplication from individual filesystems that all open-coded the same checks" * tag 'fs.idmapped.vfsuid.v5.20' of git://git.kernel.org/pub/scm/linux/kernel/git/brauner/linux: mnt_idmapping: align kernel doc and parameter order mnt_idmapping: use new helpers in mapped_fs{g,u}id() fs: port HAS_UNMAPPED_ID() to vfs{g,u}id_t mnt_idmapping: return false when comparing two invalid ids attr: fix kernel doc attr: port attribute changes to new types security: pass down mount idmapping to setattr hook quota: port quota helpers mount ids fs: port to iattr ownership update helpers fs: introduce tiny iattr ownership update helpers fs: use mount types in iattr fs: add two type safe mapping helpers mnt_idmapping: add vfs{g,u}id_t

Pull dlm updates from David Teigland: - Delay the cleanup of interrupted posix lock requests until the user space result arrives. Previously, the immediate cleanup would lead to extraneous warnings when the result arrived. - Tracepoint improvements, e.g. adding the lock resource name. - Delay the completion of lockspace creation until one full recovery cycle has completed. This allows more error cases to be returned to the caller. - Remove warnings from the locking layer about delayed network replies. The recently added midcomms warnings are much more useful. - Begin the process of deprecating two unused lock-timeout-related features. These features now require enabling via a Kconfig option, and enabling them triggers deprecation warnings.

The unhold_lkb() function decrements the lock's kref, and asserts that the ref count was not the final one. Use the kref_put release function (which should not be called) to call the assert, rather than doing the assert based on the kref_put return value. Using kill_lkb() as the release function doesn't make sense if we only want to assert. Signed-off-by: Alexander Aring <aahringo@redhat.com> Signed-off-by: David Teigland <teigland@redhat.com>

Alexander Aring authored
This patch adds a CONFIG_DLM_DEPRECATED_API Kconfig option that must be enabled to use two timeout-related features that we intend to remove in kernel v6.2. Warnings are printed if either is enabled and used. Neither has ever been used as far as we know. . The DLM_LSFL_TIMEWARN lockspace creation flag will be removed, along with the associated configfs entry for setting the timeout. Setting the flag and configfs file would cause dlm to track how long locks were waiting for reply messages. After a timeout, a kernel message would be logged, and a netlink message would be sent to userspace. Recently, midcomms messages have been added that produce much better logging about actual problems with messages. No use has ever been found for the netlink messages. . The userspace libdlm API has allowed the DLM_LKF_TIMEOUT flag with a timeout value to be set in lock requests. The lock request would be cancelled after the timeout.

With commit d257cc8c ("locking/rwsem: Make handoff bit handling more consistent"), the writer that sets the handoff bit can be interrupted out without clearing the bit if the wait queue isn't empty. This disables reader and writer optimistic lock spinning and stealing. Now if a non-first writer in the queue is somehow woken up or a new waiter enters the slowpath, it can't acquire the lock. This is not the case before commit d257cc8c as the writer that set the handoff bit will clear it when exiting out via the out_nolock path. This is less efficient as the busy rwsem stays in an unlock state for a longer time. In some cases, this new behavior may cause lockups as shown in [1] and [2]. This patch allows a non-first writer to ignore the handoff bit if it is not originally set or initiated by the first waiter. This patch is shown to be effective in fixing the lockup problem reported in [1].

If hmm_range_fault() is called with the HMM_PFN_REQ_FAULT flag and a device private PTE is found, the hmm_range::dev_private_owner page is used to determine if the device private page should not be faulted in. However, if the device private page is not owned by the caller, hmm_range_fault() returns an error instead of calling migrate_to_ram() to fault in the page. For example, if a page is migrated to GPU private memory and a RDMA fault capable NIC tries to read the migrated page, without this patch it will get an error. With this patch, the page will be migrated back to system memory and the NIC will be able to read the data.

There was a report that a task is waiting at the throttle_direct_reclaim. The pgscan_direct_throttle in vmstat was increasing. This is a bug where zone_watermark_fast returns true even when the free is very low. The commit f27ce0e1 ("page_alloc: consider highatomic reserve in watermark fast") changed the watermark fast to consider highatomic reserve. But it did not handle a negative value case which can be happened when reserved_highatomic pageblock is bigger than the actual free. If watermark is considered as ok for the negative value, allocating contexts for order-0 will consume all free pages without direct reclaim, and finally free page may become depleted except highatomic free. Then allocating contexts may fall into throttle_direct_reclaim. This symptom may easily happen in a system where wmark min is low and other reclaimers like kswapd does not make free pages quickly. Handle the negative case by using MIN.

We can see the "ROM Size" is different in the following outputs: [root@linux loongson]# cat /sys/firmware/loongson/boardinfo BIOS Information Vendor : Loongson Version : vUDK2018-LoongArch-V2.0.pre-beta8 ROM Size : 63 KB Release Date : 06/15/2022 Board Information Manufacturer : Loongson Board Name : Loongson-LS3A5000-7A1000-1w-A2101 Family : LOONGSON64 [root@linux loongson]# dmidecode | head -11 ... Handle 0x0000, DMI type 0, 26 bytes BIOS Information Vendor: Loongson Version: vUDK2018-LoongArch-V2.0.pre-beta8 Release Date: 06/15/2022 ROM Size: 4 MB According to "BIOS Information (Type 0) structure" in the SMBIOS Reference Specification [1], it shows 64K * (n+1) is the size of the physical device containing the BIOS if the size is less than 16M. Additionally, we can see the related code in dmidecode [2]: u64 s = { .l = (code1 + 1) << 6 }; So the output of dmidecode is correct, the output of boardinfo is wrong, fix it. By the way, at present no need to consider the size is 16M or greater on LoongArch, because it is usually 4M or 8M which is enough to use.

In file ptrace.c, function fpr_set does not copy fcsr data from ubuf to kbuf. That's the reason why fcsr cannot be modified by ptrace. This patch fixs this problem and allows users using ptrace to modify the fcsr.

Current calculation of shared cache size is from the node (die) scope, but we hope 'lscpu' to show the shared cache size of the whole package for multi-die chips (e.g., Loongson-3C5000L, which contains 4 dies in one package). So fix it by multiplying nodes_per_package. Signed-off-by: Huacai Chen <chenhuacai@loongson.cn>
