* scsi: target: core: Add CONTROL field for trace eventsRoman Bolshakov2020-10-291-6/+6
| | | | | | | | | | | | | | | | | | | | | | | | | [ Upstream commit 7010645ba7256992818b518163f46bd4cdf8002a ] trace-cmd report doesn't show events from target subsystem because scsi_command_size() leaks through event format string: [target:target_sequencer_start] function scsi_command_size not defined [target:target_cmd_complete] function scsi_command_size not defined Addition of scsi_command_size() to plugin_scsi.c in trace-cmd doesn't help because an expression is used inside TP_printk(). trace-cmd event parser doesn't understand minus sign inside [ ]: Error: expected ']' but read '-' Rather than duplicating kernel code in plugin_scsi.c, provide a dedicated field for CONTROL byte.

* writeback: Fix sync livelock due to b_dirty_time processingJan Kara2020-09-031-7/+6
| | | | | | | | | | | | | | | | | | | | | commit f9cae926f35e8230330f28c7b743ad088611a8de upstream. When we are processing writeback for sync(2), move_expired_inodes() didn't set any inode expiry value (older_than_this). This can result in writeback never completing if there's steady stream of inodes added to b_dirty_time list as writeback rechecks dirty lists after each writeback round whether there's more work to be done. Fix the problem by using sync(2) start time is inode expiry value when processing b_dirty_time list similarly as for ordinarily dirtied inodes. This requires some refactoring of older_than_this handling which simplifies the code noticeably as a bonus.

* ext4: force inode writes when nfsd calls commit_metadata()Theodore Ts'o2019-01-091-0/+20
| | | | | | | | | | | | | | | | | | | | | commit fde872682e175743e0c3ef939c89e3c6008a1529 upstream. Some time back, nfsd switched from calling vfs_fsync() to using a new commit_metadata() hook in export_operations(). If the file system did not provide a commit_metadata() hook, it fell back to using sync_inode_metadata(). Unfortunately doesn't work on all file systems. In particular, it doesn't work on ext4 due to how the inode gets journalled --- the VFS writeback code will not always call ext4_write_inode(). So we need to provide our own ext4_nfs_commit_metdata() method which calls ext4_write_inode() directly.

* tracing/hrtimer: Fix tracing bugs by taking all clock bases and modes into ↵Anna-Maria Gleixner2018-05-301-4/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | account [ Upstream commit 91633eed73a3ac37aaece5c8c1f93a18bae616a9 ] So far only CLOCK_MONOTONIC and CLOCK_REALTIME were taken into account as well as HRTIMER_MODE_ABS/REL in the hrtimer_init tracepoint. The query for detecting the ABS or REL timer modes is not valid anymore, it got broken by the introduction of HRTIMER_MODE_PINNED. HRTIMER_MODE_PINNED is not evaluated in the hrtimer_init() call, but for the sake of completeness print all given modes.

* tracing/x86/xen: Remove zero data size trace events ↵Steven Rostedt (VMware)2018-05-221-16/+0
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | trace_xen_mmu_flush_tlb{_all} commit 45dd9b0666a162f8e4be76096716670cf1741f0e upstream. Doing an audit of trace events, I discovered two trace events in the xen subsystem that use a hack to create zero data size trace events. This is not what trace events are for. Trace events add memory footprint overhead, and if all you need to do is see if a function is hit or not, simply make that function noinline and use function tracer filtering. Worse yet, the hack used was: __array(char, x, 0) Which creates a static string of zero in length. There's assumptions about such constructs in ftrace that this is a dynamic string that is nul terminated. This is not the case with these tracepoints and can cause problems in various parts of ftrace. Nuke the trace events!

| | | | | | | | | | | | | | | | | | | | | | commit bf7165cfa23695c51998231c4efa080fe1d3548d upstream. There are several trace include files that define TRACE_INCLUDE_FILE.

* swiotlb: Add swiotlb=noforce debug optionGeert Uytterhoeven2017-01-261-1/+2
| | | | | | | | | | | | | | | | | | | | | commit fff5d99225107f5f13fe4a9805adc2a1c4b5fb00 upstream. On architectures like arm64, swiotlb is tied intimately to the core architecture DMA support. In addition, ZONE_DMA cannot be disabled. To aid debugging and catch devices not supporting DMA to memory outside the 32-bit address space, add a kernel command line option "swiotlb=noforce", which disables the use of bounce buffers. If specified, trying to map memory that cannot be used with DMA will fail, and a rate-limited warning will be printed. Note that io_tlb_nslabs is set to 1, which is the minimal supported value.

* | mm, compaction: rename COMPACT_PARTIAL to COMPACT_SUCCESSVlastimil Babka2016-10-071-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | COMPACT_PARTIAL has historically meant that compaction returned after doing some work without fully compacting a zone. It however didn't distinguish if compaction terminated because it succeeded in creating the requested high-order page. This has changed recently and now we only return COMPACT_PARTIAL when compaction thinks it succeeded, or the high-order watermark check in compaction_suitable() passes and no compaction needs to be done. So at this point we can make the return value clearer by renaming it to COMPACT_SUCCESS. The next patch will remove some redundant tests for success where compaction just returned COMPACT_SUCCESS.

Whilst we're at it: (1) Add to the tx_data tracepoint an indication of whether or not we're retransmitting a data packet. (2) When we're deciding whether or not to request an ACK, rather than checking if we're in fast-retransmit mode check instead if we're retransmitting. (3) Don't invoke the lose_skb tracepoint when losing a Tx packet as we're not altering the sk_buff refcount nor are we just seeing it after getting it off the Tx list. (4) The rxrpc_skb_tx_lost note is then no longer used so remove it. (5) rxrpc_lose_skb() no longer needs to deal with rxrpc_skb_tx_lost. Signed-off-by: David Howells <dhowells@redhat.com>

A tracepoint is added to log the state of the congestion management algorithm and the decisions it makes. Notes: (1) Since we send fixed-size DATA packets (apart from the final packet in each phase), counters and calculations are in terms of packets rather than bytes. (2) The ACK packet carries the equivalent of TCP SACK. (3) The FLIGHT_SIZE calculation in RFC 5681 doesn't seem particularly suited to SACK of a small number of packets. It seems that, almost inevitably, by the time three 'duplicate' ACKs have been seen, we have narrowed the loss down to one or two missing packets, and the FLIGHT_SIZE calculation ends up as 2. (4) In rxrpc_resend(), if there was no data that apparently needed retransmission, we transmit a PING ACK to ask the peer to tell us what its Rx window state is.

(2) Distinguish Rx from Tx packets and account them separately. This requires the call phase to be tracked so that we know what we might find in rxtx_buffer[]. (3) Add a parameter to rxrpc_{new,see,get,free}_skb() to indicate the event type. (4) A pair of 'rotate' events are added to indicate packets that are about to be rotated out of the Rx and Tx windows.

Currently we have three drivers in tree which all have a global list which they iterate over. With multi instance they support don't need their private list and the functionality has been moved into core code. Plus we hold the hotplug lock in core so no cpus comes/goes while instances are registered and we do rollback in error case :) Signed-off-by: Thomas Gleixner <tglx@linutronix.de> Signed-off-by: Sebastian Andrzej Siewior <bigeasy@linutronix.de> Cc: Mark Rutland <mark.rutland@arm.com> Cc: Peter Zijlstra <peterz@infradead.org> Cc: Will Deacon <will.deacon@arm.com> Cc: rt@linutronix.de Link: http://lkml.kernel.org/r/1471024183-12666-3-git-send-email-bigeasy@linutronix.de Signed-off-by: Thomas Gleixner <tglx@linutronix.de>
