2023-10-04mm/damon/core: add a tracepoint for damos apply target regionsSeongJae Park1-0/+39
Patch series "mm/damon: add a tracepoint for damos apply target regions", v2. DAMON provides damon_aggregated tracepoint to let users record full monitoring results. Sometimes, users need to record monitoring results of specific pattern. DAMOS tried regions directory of DAMON sysfs interface allows it, but the interface is mainly designed for snapshots and therefore would be inefficient for such recording. Implement yet another tracepoint for efficient support of the usecase. This patch (of 2): DAMON provides damon_aggregated tracepoint, which exposes details of each region and its access monitoring results. It is useful for getting whole monitoring results, e.g., for recording purposes. For investigations of DAMOS, DAMON Sysfs interface provides DAMOS statistics and tried_regions directory. But, those provides only statistics and snapshots. If the scheme is frequently applied and if the user needs to know every detail of DAMOS behavior, the snapshot-based interface could be insufficient and expensive. As a last resort, userspace users need to record the all monitoring results via damon_aggregated tracepoint and simulate how DAMOS would worked. It is unnecessarily complicated. DAMON kernel API users, meanwhile, can do that easily via before_damos_apply() callback field of 'struct damon_callback', though. Add a tracepoint that will be called just after before_damos_apply() callback for more convenient investigations of DAMOS. The tracepoint exposes all details about each regions, similar to damon_aggregated tracepoint. Please note that DAMOS is currently not only for memory management but also for query-like efficient monitoring results retrievals (when 'stat' action is used). Until now, only statistics or snapshots were supported. Addition of this tracepoint allows efficient full recording of DAMOS-based filtered monitoring results.

2023-09-21vsock/virtio: MSG_ZEROCOPY flag supportArseniy Krasnov1-4/+8
This adds handling of MSG_ZEROCOPY flag on transmission path: 1) If this flag is set and zerocopy transmission is possible (enabled in socket options and transport allows zerocopy), then non-linear skb will be created and filled with the pages of user's buffer. Pages of user's buffer are locked in memory by 'get_user_pages()'. 2) Replaces way of skb owning: instead of 'skb_set_owner_sk_safe()' it calls 'skb_set_owner_w()'. Reason of this change is that '__zerocopy_sg_from_iter()' increments 'sk_wmem_alloc' of socket, so to decrease this field correctly, proper skb destructor is needed: 'sock_wfree()'. This destructor is set by 'skb_set_owner_w()'. 3) Adds new callback to 'struct virtio_transport': 'can_msgzerocopy'. If this callback is set, then transport needs extra check to be able to send provided number of buffers in zerocopy mode. Currently, the only transport that needs this callback set is virtio, because this transport adds new buffers to the virtio queue and we need to check, that number of these buffers is less than size of the queue (it is required by virtio spec). vhost and loopback transports don't need this check.

The logical unit information is missing from the UFS command tracing output. Although the device name is logged, e.g. 13200000.ufs, this name does not include logical unit information.

2023-09-13smp: Change function signatures to use call_single_data_tLeonardo Bras1-4/+4
call_single_data_t is a size-aligned typedef of struct __call_single_data. This alignment is desirable in order to have smp_call_function*() avoid bouncing an extra cacheline in case of an unaligned csd, given this would hurt performance. Since the removal of struct request->csd in commit 660e802c76c8 ("blk-mq: use percpu csd to remote complete instead of per-rq csd") there are no current users of smp_call_function*() with unaligned csd. Change every 'struct __call_single_data' function parameter to 'call_single_data_t', so we have warnings if any new code tries to introduce an smp_call_function*() call with unaligned csd.

2023-09-11arch: Remove Itanium (IA-64) architectureArd Biesheuvel1-1/+1
The Itanium architecture is obsolete, and an informal survey [0] reveals that any residual use of Itanium hardware in production is mostly HP-UX or OpenVMS based. The use of Linux on Itanium appears to be limited to enthusiasts that occasionally boot a fresh Linux kernel to see whether things are still working as intended, and perhaps to churn out some distro packages that are rarely used in practice. None of the original companies behind Itanium still produce or support any hardware or software for the architecture, and it is listed as 'Orphaned' in the MAINTAINERS file, as apparently, none of the engineers that contributed on behalf of those companies (nor anyone else, for that matter) have been willing to support or maintain the architecture upstream or even be responsible for applying the odd fix. The Intel firmware team removed all IA-64 support from the Tianocore/EDK2 reference implementation of EFI in 2018. (Itanium is the original architecture for which EFI was developed, and the way Linux supports it deviates significantly from other architectures.) Some distros, such as Debian and Gentoo, still maintain [unofficial] ia64 ports, but many have dropped support years ago. While the argument is being made [1] that there is a 'for the common good' angle to being able to build and run existing projects such as the Grid Community Toolkit [2] on Itanium for interoperability testing, the fact remains that none of those projects are known to be deployed on Linux/ia64, and very few people actually have access to such a system in the first place. Even if there were ways imaginable in which Linux/ia64 could be put to good use today, what matters is whether anyone is actually doing that, and this does not appear to be the case. There are no emulators widely available, and so boot testing Itanium is generally infeasible for ordinary contributors. GCC still supports IA-64 but its compile farm [3] no longer has any IA-64 machines. GLIBC would like to get rid of IA-64 [4] too because it would permit some overdue code cleanups. In summary, the benefits to the ecosystem of having IA-64 be part of it are mostly theoretical, whereas the maintenance overhead of keeping it supported is real. So let's rip off the band aid, and remove the IA-64 arch code entirely. This follows the timeline proposed by the Debian/ia64 maintainer [5], which removes support in a controlled manner, leaving IA-64 in a known good state in the most recent LTS release. Other projects will follow once the kernel support is removed.

2023-09-01tracing: Replace strlcpy with strscpy in trace/events/task.hAzeem Shaikh1-1/+1
strlcpy() reads the entire source buffer first. This read may exceed the destination size limit. This is both inefficient and can lead to linear read overflows if a source string is not NUL-terminated [1]. In an effort to remove strlcpy() completely [2], replace strlcpy() here with strscpy(). No return values were used, so direct replacement is safe.

Pull nfsd updates from Chuck Lever: "I'm thrilled to announce that the Linux in-kernel NFS server now offers NFSv4 write delegations. A write delegation enables a client to cache data and metadata for a single file more aggressively, reducing network round trips and server workload. Many thanks to Dai Ngo for contributing this facility, and to Jeff Layton and Neil Brown for reviewing and testing it. This release also sees the removal of all support for DES- and triple-DES-based Kerberos encryption types in the kernel's SunRPC implementation. These encryption types have been deprecated by the Internet community for years and are considered insecure. This change affects both the in-kernel NFS client and server. The server's UDP and TCP socket transports have now fully adopted David Howells' new bio_vec iterator so that no more than one sendmsg() call is needed to transmit each RPC message. In particular, this helps kTLS optimize record boundaries when sending RPC-with-TLS replies, and it takes the server a baby step closer to handling file I/O via folios. We've begun work on overhauling the SunRPC thread scheduler to remove a costly linked-list walk when looking for an idle RPC service thread to wake. The pre-requisites are included in this release.

2023-08-29SUNRPC: Move trace_svc_xprt_enqueueChuck Lever1-9/+9
The xpt_flags field frequently changes between the time that svc_xprt_ready() grabs a copy and execution flow arrives at the tracepoint at the tail of svc_xprt_enqueue(). In fact, there's usually a sleep/wake-up in there, so those flags are almost guaranteed to be different. It would be more useful to record the exact flags that were used to decide whether the transport is ready, so move the tracepoint. Moving it means the tracepoint can't pick up the waker's pid.

2023-08-21btrfs: remove v0 extent handlingQu Wenruo1-1/+0
The v0 extent item has been deprecated for a long time, and we don't have any report from the community either. So it's time to remove the v0 extent specific error handling, and just treat them as regular extent tree corruption. This patch would remove the btrfs_print_v0_err() helper, and enhance the involved error handling to treat them just as any extent tree corruption. No reports regarding v0 extents have been seen since the graceful handling was added in 2018. This involves: - btrfs_backref_add_tree_node() This change is a little tricky, the new code is changed to only handle BTRFS_TREE_BLOCK_REF_KEY and BTRFS_SHARED_BLOCK_REF_KEY. But this is safe, as we have rejected any unknown inline refs through btrfs_get_extent_inline_ref_type(). For keyed backrefs, we're safe to skip anything we don't know (that's if it can pass tree-checker in the first place). - btrfs_lookup_extent_info() - lookup_inline_extent_backref() - run_delayed_extent_op() - __btrfs_free_extent() - add_tree_block() Regular error handling of unexpected extent tree item, and abort transaction (if we have a trans handle). - remove_extent_data_ref() It's pretty much the same as the regular rejection of unknown backref key. But for this particular case, we can also remove a BUG_ON(). - extent_data_ref_count() We can remove the BTRFS_EXTENT_REF_V0_KEY BUG_ON(), as it would be rejected by the only caller. - btrfs_print_leaf() Remove the handling for BTRFS_EXTENT_REF_V0_KEY.

2023-08-21btrfs: tracepoints: simplify raid56 eventsQu Wenruo1-27/+2
After commit 6bfd0133bee2 ("btrfs: raid56: switch scrub path to use a single function"), the raid56 implementation no longer uses different endio functions for RMW/recover/scrub. All read operations end in submit_read_wait_bio_list(), while all write operations end in submit_write_bios(). This means quite some trace events are out-of-date and no longer utilized. This patch would unify the trace events into just two: - trace_raid56_read() Replaces trace_raid56_read_partial(), trace_raid56_scrub_read() and trace_raid56_scrub_read_recover(). - trace_raid56_write() Replaces trace_raid56_write_stripe() and trace_raid56_scrub_write_stripe().

This patch (of 4): kernel.h is being used as a dump for all kinds of stuff for a long time. The COUNT_ARGS() and CONCATENATE() macros may be used in some places without need of the full kernel.h dependency train with it. Here is the attempt on cleaning it up by splitting out these macros().

2023-08-03net: invert the netdevice.h vs xdp.h dependencyJakub Kicinski1-0/+1
xdp.h is far more specific and is included in only 67 other files vs netdevice.h's 1538 include sites. Make xdp.h include netdevice.h, instead of the other way around. This decreases the incremental allmodconfig builds size when xdp.h is touched from 5947 to 662 objects. Move bpf_prog_run_xdp() to xdp.h, seems appropriate and filter.h is a mega-header in its own right so it's nice to avoid xdp.h getting included there as well. The only unfortunate part is that the typedef for xdp_features_t has to move to netdevice.h, since its embedded in struct netdevice.

2023-08-02bpf, xdp: Add tracepoint to xdp attaching failureLeon Hwang1-0/+17
When error happens in dev_xdp_attach(), it should have a way to tell users the error message like the netlink approach. To avoid breaking uapi, adding a tracepoint in bpf_xdp_link_attach() is an appropriate way to notify users the error message. Hence, bpf libraries are able to retrieve the error message by this tracepoint, and then report the error message to users.

2023-08-02fs: add CONFIG_BUFFER_HEADChristoph Hellwig1-0/+2
Add a new config option that controls building the buffer_head code, and select it from all file systems and stacking drivers that need it. For the block device nodes and alternative iomap based buffered I/O path is provided when buffer_head support is not enabled, and iomap needs a a small tweak to define the IOMAP_F_BUFFER_HEAD flag to 0 to not call into the buffer_head code when it doesn't exist. Otherwise this is just Kconfig and ifdef changes.

2023-07-17blk-wbt: Replace strlcpy with strscpyAzeem Shaikh1-4/+4
strlcpy() reads the entire source buffer first. This read may exceed the destination size limit. This is both inefficient and can lead to linear read overflows if a source string is not NUL-terminated [1]. In an effort to remove strlcpy() completely [2], replace strlcpy() here with strscpy(). No return values were used, so direct replacement is safe.
