* Switch from _Noreturn to __attribute__((noreturn))Brian Behlendorf2022-03-233-8/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Parts of the Linux kernel build system struggle with _Noreturn. This results in the following warnings when building on RHEL 8.5, and likely other environments. Switch to using the __attribute__((noreturn)). warning: objtool: dbuf_free_range()+0x2b8: return with modified stack frame warning: objtool: dbuf_free_range()+0x0: stack state mismatch: cfa1=7+40 cfa2=7+8 ... WARNING: EXPORT symbol "arc_buf_size" [zfs.ko] version generation failed, symbol will not be versioned. WARNING: EXPORT symbol "spa_open" [zfs.ko] version generation failed, symbol will not be versioned. ... Additionally, __thread_exit() has been renamed spl_thread_exit() and made a static inline function. This was needed because the kernel will generate a warning for symbols which are __attribute__((noreturn)) and then exported with EXPORT_SYMBOL. While we could continue to use _Noreturn in user space I've also switched it to __attribute__((noreturn)) purely for consistency throughout the code base.

* Fix ENOSPC when unlinking multiple files from full poolBrian Behlendorf2022-03-081-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | When unlinking multiple files from a pool at 100% capacity, it was possible for ENOSPC to be returned after the first unlink. e.g. rm -f /mnt/fs/test1.0.0 /mnt/fs/test1.1.0 /mnt/fs/test1.2.0 rm: cannot remove '/mnt/fs/test1.1.0': No space left on device rm: cannot remove '/mnt/fs/test1.2.0': No space left on device After waiting for the pending deferred frees from the first unlink to be processed the remaining files can then be unlinked. This is caused by the quota limit in dsl_dir_tempreserve_impl() being temporarily decreased to the allocatable pool capacity less any deferred free space. This is resolved using the existing mechanism of returning ERESTART when over quota as long as we know enough space will shortly be available after processing the pending deferred frees.

This commit allows additional file level attributes to be updated and retrieved for Linux. These include the flags stored in the upper half of z_pflags only. Two new IOCTLs have been added for this purpose. ZFS_IOC_GETDOSFLAGS can be used to retrieve the attributes, while ZFS_IOC_SETDOSFLAGS can be used to update the attributes. Attributes that are allowed to be updated include ZFS_IMMUTABLE, ZFS_APPENDONLY, ZFS_NOUNLINK, ZFS_ARCHIVE, ZFS_NODUMP, ZFS_SYSTEM, ZFS_HIDDEN, ZFS_READONLY, ZFS_REPARSE, ZFS_OFFLINE and ZFS_SPARSE.

* Use _Noreturn (C11; GNU89) properlyAlejandro Colomar2022-03-043-11/+11
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A function that returns with no value is a different thing from a function that doesn't return at all. Those are two orthogonal concepts, commonly confused. pthread_create(3) expects a pointer to a start routine that has a very precise prototype: void *(*start_routine)(void *); However, other thread functions, such as kernel ones, expect: void (*start_routine)(void *); Providing a different one is incorrect, and has only been working because the ABIs happen to produce a compatible function. We should use '_Noreturn void', since it's the natural type, and then provide a '_Noreturn void *' wrapper for pthread functions. For consistency, replace most cases of __NORETURN or __attribute__((noreturn)) by _Noreturn. _Noreturn is understood by -std=gnu89, so it should be safe to use everywhere.

* log xattr=sa create/remove/update to ZILJitendra Patidar2022-02-224-3/+15

But for xattr=on, it does log to ZIL and zil_commit() is done, if sync=always is set on dataset. This provides sync semantics for xattr=on with sync=always set on dataset. For the xattr=sa implementation, it doesn't log to ZIL, so, even with sync=always, xattrs are not guaranteed to be synced before xattr call returns to caller. So, xattr can be lost if system crash happens, before txg carrying xattr transaction is synced. This change adds xattr=sa logging to ZIL on xattr create/remove/update and xattrs are synced to ZIL (zil_commit() done) for sync=always. This makes xattr=sa behavior similar to xattr=on. Implementation notes: The actual logging is fairly straight-forward and does not warrant additional explanation. However, it has been 14 years since we last added new TX types to the ZIL [1], hence this is the first time we do it after the introduction of zpool features. Therefore, here is an overview of the feature activation and deactivation workflow: 1. The feature must be enabled. Otherwise, we don't log the new record type. This ensures compatibility with older software. 2. The feature is activated per-dataset, since the ZIL is per-dataset. 3. If the feature is enabled and dataset is not for zvol, any append to the ZIL chain will activate the feature for the dataset. Likewise for starting a new ZIL chain. 4. A dataset that doesn't have a ZIL chain has the feature deactivated. We ensure (3) by activating on the first zil_commit() after the feature was enabled. Since activating the features requires waiting for txg sync, the first zil_commit() after enabling the feature will be slower than usual. The downside is that this is really a conservative approximation: even if we never append a 'TX_SETSAXATTR' to the ZIL chain, we pay the penalty for feature activation. The upside is that the user is in control of when we pay the penalty, i.e., upon enabling the feature. We ensure (4) by hooking into zil_sync(), where ZIL destroy actually happens. One more piece on feature activation, since it's spread across multiple functions: zil_commit() zil_process_commit_list() if lwb == NULL // first zil_commit since zil_open zil_create() if no log block pointer in ZIL header: if feature enabled and not active: // CASE 1 enable, COALESCE txg wait with dmu_tx that allocated the log block else // log block was allocated earlier than this zil_open if feature enabled and not active: // CASE 2 enable, EXPLICIT txg wait else // already have an in-DRAM LWB if feature enabled and not active: // this happens when we enable the feature after zil_create // CASE 3 enable, EXPLICIT txg wait [1] https://github.com/illumos/illumos-gate/commit/da6c28aaf62fa55f0fdb8004aa40f88f23bf53f0 Reviewed-by: Matthew Ahrens <[email protected]> Reviewed-by: Christian Schwarz <[email protected]> Reviewed-by: Ahelenia Ziemiańska <[email protected]> Reviewed-by: Ryan Moeller <[email protected]> Reviewed-by: Brian Behlendorf <[email protected]> Signed-off-by: Jitendra Patidar <[email protected]> Closes #8768 Closes #9078

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | ZFS on Linux originally implemented xattr namespaces in a way that is incompatible with other operating systems. On illumos, xattrs do not have namespaces. Every xattr name is visible. FreeBSD has two universally defined namespaces: EXTATTR_NAMESPACE_USER and EXTATTR_NAMESPACE_SYSTEM. The system namespace is used for protected FreeBSD-specific attributes such as MAC labels and pnfs state. These attributes have the namespace string "freebsd:system:" prefixed to the name in the encoding scheme used by ZFS. The user namespace is used for general purpose user attributes and obeys normal access control mechanisms. These attributes have no namespace string prefixed, so xattrs written on illumos are accessible in the user namespace on FreeBSD, and xattrs written to the user namespace on FreeBSD are accessible by the same name on illumos. Linux has several xattr namespaces. On Linux, ZFS encodes the namespace in the xattr name for every namespace, including the user namespace. As a consequence, an xattr in the user namespace with the name "foo" is stored by ZFS with the name "user.foo" and therefore appears on FreeBSD and illumos to have the name "user.foo" rather than "foo". Conversely, none of the xattrs written on FreeBSD or illumos are accessible on Linux unless the name happens to be prefixed with one of the Linux xattr namespaces, in which case the namespace is stripped from the name. This makes xattrs entirely incompatible between Linux and other platforms. We want to make the encoding of user namespace xattrs compatible across platforms. A critical requirement of this compatibility is for xattrs from existing pools from FreeBSD and illumos to be accessible by the same names in the user namespace on Linux. It is also necessary that existing pools with xattrs written by Linux retain access to those xattrs by the same names on Linux. Making user namespace xattrs from Linux accessible by the correct names on other platforms is important. The handling of other namespaces is not required to be consistent. Add a fallback mechanism for listing and getting xattrs to treat xattrs as being in the user namespace if they do not match a known prefix. Do not allow setting or getting xattrs with a name that is prefixed with one of the namespace names used by ZFS on supported platforms. Allow choosing between legacy illumos and FreeBSD compatibility and legacy Linux compatibility with a new tunable. This facilitates replication and migration of pools between hosts with different compatibility needs. The tunable controls whether or not to prefix the namespace to the name. If the xattr is already present with the alternate prefix, remove it so only the new version persists. By default the platform's existing convention is used.

* Linux 5.16 compat: don't use XSTATE_XSAVE to save FPU stateAttila Fülöp2022-02-091-2/+123
| | | | | | | | | | | | | | | | | | | | | | | | | | | Linux 5.16 moved XSTATE_XSAVE and XSTATE_XRESTORE out of our reach, so add our own XSAVE{,OPT,S} code and use it for Linux 5.16. Please note that this differs from previous behavior in that it won't handle exceptions created by XSAVE an XRSTOR. This is sensible for three reasons. - Exceptions during XSAVE and XRSTOR can only occur if the feature is not supported or enabled or the memory operand isn't aligned on a 64 byte boundary. If this happens something else went terribly wrong, and it may be better to stop execution. - Previously we just printed a warning and didn't handle the fault, this is arguable for the above reason. - All other *SAVE instruction also don't handle exceptions, so this at least aligns behavior. Finally add a test to catch such a regression in the future.

* zvol: make calls to platform ops staticChristian Schwarz2022-02-071-12/+8
| | | | | | | | | | | | | | | | | | | | | There's no need to make the platform ops dynamic dispatch. This change replaces the dynamic dispatch with static calls to the platform-specific functions. To avoid name collisions, prefix all platform-specific functions with `zvol_os_`. I actually find `zvol_..._os` slightly nicer to read in the calling code, but having it as a prefix is useful. Advantage: - easier jump-to-definition / grepping - potential benefits to static analysis - better legibility Future work: also prefix remaining `static` functions in zvol_os.c.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | `configure` now accepts `--enable-asan` and `--enable-ubsan` switches which results in passing `-fsanitize=address` and `-fsanitize=undefined`, respectively, to the compiler. Those flags are enabled in GitHub workflows for ZTS and zloop. Errors reported by both instrumentations are corrected, except for: - Memory leak reporting is (temporarily) suppressed. The cost of fixing them is relatively high compared to the gains. - Checksum computing functions in `module/zcommon/zfs_fletcher*` have UBSan errors suppressed. It is completely impractical to enforce 64-byte payload alignment there due to performance impact. - There's no ASan heap poisoning in `module/zstd/lib/zstd.c`. A custom memory allocator is used there rendering that measure unfeasible. - Memory leaks detection has to be suppressed for `cmd/zvol_id`. `zvol_id` is run by udev with the help of `ptrace(2)`. Tracing is incompatible with memory leaks detection.

* spl: Don't check FreeBSD rwlocks for double initialization (#13019)Mark Johnston2022-01-311-5/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This checking breaks KMSAN since it effectively loads from uninitialized memory to see if the lock is already initialized. This happens in dnode_cons() for example. This checking is not very useful, partly due to UMA's memory trashing, and is already disabled for mutexes. Make mutexes and rwlocks consistent: remove double-initialization checking for rwlocks, and pass SX_NEW to disable the same checking in lock_init(). No functional change intended, this affects only debug builds. As a side note, kmem cache constructors/destructors are implemented suboptimally on FreeBSD. FreeBSD's slab allocator, UMA, supports two pairs of constructors/destructors: ctor/dtor and init/fini. The former are called upon every allocation and free of an item, while the latter are called when an item is imported or released from a zone, respectively. That is, when a slab is allocated to a particular cache, it is subdivided into items, and init is called on each. fini is called when the slab is being prepared to be freed back to the system. The intent is for them to initialize static fields such as locks, which do not need to be initialized upon each allocation of an item. In illumos, kmem_cache constructors/destructors correspond to UMA's init/fini callbacks. However, in the SPL they are implemented as UMA ctor/dtors, meaning that they get called far more often than necessary. This may be difficult to fix, since new code may assume the kmem cache ctor/dtors are in fact called upon each allocation/free, and there doesn't seem to be a clear way to implement the intended semantics on Linux.
