This is a long-term stable ABI and has to be backwards +// compatible to deal with mismatching Producer and Service versions. +// +// Overview +// -------- +// SMB := "Shared Memory Buffer". +// In the most typical case of a multi-process architecture (i.e. Producer and +// Service are hosted by different processes), a Producer means almost always +// a "client process producing data" (almost: in some cases a process might host +// > 1 Producer, if it links two libraries, independent of each other, that both +// use Perfetto tracing). +// The Service has one SMB for each Producer. +// A producer has one or (typically) more data sources. They all share the same +// SMB. +// The SMB is a staging area to decouple data sources living in the Producer +// and allow them to do non-blocking async writes. +// The SMB is *not* the ultimate logging buffer seen by the Consumer. That one +// is larger (~MBs) and not shared with Producers. +// Each SMB is small, typically few KB. Its size is configurable by the producer +// within a max limit of ~MB (see kMaxShmSize in tracing_service_impl.cc). +// The SMB is partitioned into fixed-size Page(s). The size of the Pages are +// determined by each Producer at connection time and cannot be changed. +// Hence, different producers can have SMB(s) that have a different Page size +// from each other, but the page size will be constant throughout all the +// lifetime of the SMB. +// Page(s) are partitioned by the Producer into variable size Chunk(s): +// +// +------------+ +--------------------------+ +// | Producer 1 | <-> | SMB 1 [~32K - 1MB] | +// +------------+ +--------+--------+--------+ +// | Page | Page | Page | +// +--------+--------+--------+ +// | Chunk | | Chunk | +// +--------+ Chunk +--------+ <----+ +// | Chunk | | Chunk | | +// +--------+--------+--------+ +---------------------+ +// | Service | +// +------------+ +--------------------------+ +---------------------+ +// | Producer 2 | <-> | SMB 2 [~32K - 1MB] | /| large ring buffers | +// +------------+ +--------+--------+--------+ <--+ | (100K - several MB) | +// | Page | Page | Page | +---------------------+ +// +--------+--------+--------+ +// | Chunk | | Chunk | +// +--------+ Chunk +--------+ +// | Chunk | | Chunk | +// +--------+--------+--------+ +// +// * Sizes of both SMB and ring buffers are purely indicative and decided at +// configuration time by the Producer (for SMB sizes) and the Consumer (for the +// final ring buffer size). + +// Page +// ---- +// A page is a portion of the shared memory buffer and defines the granularity +// of the interaction between the Producer and tracing Service. When scanning +// the shared memory buffer to determine if something should be moved to the +// central logging buffers, the Service most of the times looks at and moves +// whole pages. Similarly, the Producer sends an IPC to invite the Service to +// drain the shared memory buffer only when a whole page is filled. +// Having fixed the total SMB size (hence the total memory overhead), the page +// size is a triangular tradeoff between: +// 1) IPC traffic: smaller pages -> more IPCs. +// 2) Producer lock freedom: larger pages -> larger chunks -> data sources can +// write more data without needing to swap chunks and synchronize. +// 3) Risk of write-starving the SMB: larger pages -> higher chance that the +// Service won't manage to drain them and the SMB remains full. +// The page size, on the other side, has no implications on wasted memory due to +// fragmentations (see Chunk below). +// The size of the page is chosen by the Service at connection time and stays +// fixed throughout all the lifetime of the Producer. Different producers (i.e. +// ~ different client processes) can use different page sizes. +// The page size must be an integer multiple of 4k (this is to allow VM page +// stealing optimizations) and obviously has to be an integer divisor of the +// total SMB size. + +// Chunk +// ----- +// A chunk is a portion of a Page which is written and handled by a Producer. +// A chunk contains a linear sequence of TracePacket(s) (the root proto). +// A chunk cannot be written concurrently by two data sources. Protobufs must be +// encoded as contiguous byte streams and cannot be interleaved. Therefore, on +// the Producer side, a chunk is almost always owned exclusively by one thread +// (% extremely peculiar slow-path cases). +// Chunks are essentially single-writer single-thread lock-free arenas. Locking +// happens only when a Chunk is full and a new one needs to be acquired. +// Locking happens only within the scope of a Producer process. There is no +// inter-process locking. The Producer cannot lock the Service and viceversa. +// In the worst case, any of the two can starve the SMB, by marking all chunks +// as either being read or written. But that has the only side effect of +// losing the trace data. +// The Producer can decide to partition each page into a number of limited +// configurations (e.g., 1 page == 1 chunk, 1 page == 2 chunks and so on). + +// TracePacket +// ----------- +// Is the atom of tracing. Putting aside pages and chunks a trace is merely a +// sequence of TracePacket(s). TracePacket is the root protobuf message. +// A TracePacket can span across several chunks (hence even across several +// pages). A TracePacket can therefore be >> chunk size, >> page size and even +// >> SMB size. The Chunk header carries metadata to deal with the TracePacket +// splitting case. + +// Use only explicitly-sized types below. DO NOT use size_t or any architecture +// dependent size (e.g. size_t) in the struct fields.

The service will own several instances of this class, +// at least one per active consumer (as defined in the |buffers| section of +// trace_config.proto) and will copy chunks from the producer's shared memory +// buffers into here when a CommitData IPC is received. +// +// Writing into the buffer +// ----------------------- +// Data is copied from the SMB(s) using CopyChunkUntrusted(). The buffer will +// hence contain data coming from different producers and different writer +// sequences, more specifically: +// - The service receives data by several producer(s), identified by their ID. +// - Each producer writes several sequences identified by the same WriterID. +// (they correspond to TraceWriter instances in the producer). +// - Each Writer writes, in order, several chunks. +// - Each chunk contains zero, one, or more TracePacket(s), or even just +// fragments of packets (when they span across several chunks). +// +// So at any point in time, the buffer will contain a variable number of logical +// sequences identified by the {ProducerID, WriterID} tuple. Any given chunk +// will only contain packets (or fragments) belonging to the same sequence. +// +// The buffer operates by default as a ring buffer. +// It has two overwrite policies: +// 1. kOverwrite (default): if the write pointer reaches the read pointer, old +// unread chunks will be overwritten by new chunks. +// 2. kDiscard: if the write pointer reaches the read pointer, unread chunks +// are preserved and the new chunks are discarded. Any future write becomes +// a no-op, even if the reader manages to fully catch up. This is because +// once a chunk is discarded, the sequence of packets is broken and trying +// to recover would be too hard (also due to the fact that, at the same +// time, we allow out-of-order commits and chunk re-writes). +// +// Chunks are (over)written in the same order of the CopyChunkUntrusted() calls. +// When overwriting old content, entire chunks are overwritten or clobbered. +// The buffer never leaves a partial chunk around. Chunks' payload is copied +// as-is, but their header is not and is repacked in order to keep the +// ProducerID around. +// +// Chunks are stored in the buffer next to each other. Each chunk is prefixed by +// an inline header (ChunkRecord), which contains most of the fields of the +// SharedMemoryABI ChunkHeader + the ProducerID + the size of the payload. +// It's a conventional binary object stream essentially, where each ChunkRecord +// tells where it ends and hence where to find the next one, like this: +// +// .-------------------------. 16 byte boundary +// | ChunkRecord: 16 bytes | +// | - chunk id: 4 bytes | +// | - producer id: 2 bytes | +// | - writer id: 2 bytes | +// | - #fragments: 2 bytes | +// +-----+ - record size: 2 bytes | +// | | - flags+pad: 4 bytes | +// | +-------------------------+ +// | | | +// | : Chunk payload : +// | | | +// | +-------------------------+ +// | | Optional padding | +// +---> +-------------------------+ 16 byte boundary +// | ChunkRecord | +// : : +// Chunks stored in the buffer are always rounded up to 16 bytes (that is +// sizeof(ChunkRecord)), in order to avoid further inner fragmentation. +// Special "padding" chunks can be put in the buffer, e.g. in the case when we +// try to write a chunk of size N while the write pointer is at the end of the +// buffer, but the write pointer is < N bytes from the end (and hence needs to +// wrap over). +// Because of this, the buffer is self-describing: the contents of the buffer +// can be reconstructed by just looking at the buffer content (this will be +// quite useful in future to recover the buffer from crash reports). +// +// However, in order to keep some operations (patching and reading) fast, a +// lookaside index is maintained (in |index_|), keeping each chunk in the buffer +// indexed by their {ProducerID, WriterID, ChunkID} tuple. +// +// Patching data out-of-band +// ------------------------- +// This buffer also supports patching chunks' payload out-of-band, after they +// have been stored. This is to allow producers to backfill the "size" fields +// of the protos that spawn across several chunks, when the previous chunks are +// returned to the service. The MaybePatchChunkContents() deals with the fact +// that a chunk might have been lost (because of wrapping) by the time the OOB +// IPC comes. +// +// Reading from the buffer +// ----------------------- +// This class supports one reader only (the consumer). Reads are NOT idempotent +// as they move the read cursors around. Reading back the buffer is the most +// conceptually complex part. The ReadNextTracePacket() method operates with +// whole packet granularity. Packets are returned only when all their fragments +// are available. +// This class takes care of: +// - Gluing packets within the same sequence, even if they are not stored +// adjacently in the buffer. +// - Re-ordering chunks within a sequence (using the ChunkID, which wraps). +// - Detecting holes in packet fragments (because of loss of chunks). +// Reads guarantee that packets for the same sequence are read in FIFO order +// (according to their ChunkID), but don't give any guarantee about the read +// order of packets from different sequences, see comments in +// ReadNextTracePacket() below. +class TraceBuffer { + public: + static const size_t InlineChunkHeaderSize; // For test/fake_packet.{cc,h}. + + // See comment in the header above. + enum OverwritePolicy { kOverwrite, kDiscard }; + + // Argument for out-of-band patches applied through TryPatchChunkContents(). + struct Patch { + // From SharedMemoryABI::kPacketHeaderSize. + static constexpr size_t kSize = 4; + + size_t offset_untrusted; + std::array<uint8_t, kSize> data; + }; + + // Identifiers that are constant for a packet sequence. + struct PacketSequenceProperties { + ProducerID producer_id_trusted; + ClientIdentity client_identity_trusted; + WriterID writer_id; + + uid_t producer_uid_trusted() const { return client_identity_trusted.uid(); } + pid_t producer_pid_trusted() const { return client_identity_trusted.pid(); } + }; + + // Holds the "used chunk" stats for each <Producer, Writer> tuple. + struct WriterStats { + Histogram<8, 32, 128, 512, 1024, 2048, 4096, 8192, 12288, 16384> + used_chunk_hist; + }; + + using WriterStatsMap = base::FlatHashMap<ProducerAndWriterID, + WriterStats, + std::hash<ProducerAndWriterID>, + base::QuadraticProbe, + /*AppendOnly=*/true>; + + // Can return nullptr if the memory allocation fails. + static std::unique_ptr<TraceBuffer> Create(size_t size_in_bytes, + OverwritePolicy = kOverwrite); + + ~TraceBuffer(); + + // Copies a Chunk from a producer Shared Memory Buffer into the trace buffer. + // |src| points to the first packet in the SharedMemoryABI's chunk shared with + // an untrusted producer.
