*	executor: add runner mode	Dmitry Vyukov	2024-06-24	1	-1/+26
\| \| \| \| \| \| \|	Move all syz-fuzzer logic into syz-executor and remove syz-fuzzer. Also restore syz-runtest functionality in the manager. Update #4917 (sets most signal handlers to SIG_IGN)
*	pkg/fuzzer: improve handling of signal for non-target calls	Dmitry Vyukov	2024-06-03	1	-4/+3
\| \| \| \| \| \| \|	During deflake/minimization we have 1 target call that should be handled specially: during triage we want all signal, during minimization we want new+target signal. For the rest of the calls we can do normal handling: collect new signal and start triage if we see any new signal.
*	syz-manager: add corpus triage mode	Dmitry Vyukov	2024-06-03	1	-11/+0
\| \| \| \| \| \| \| \|	Add corpus triage mode and support it in testbed. This is useful to benchmark just the triage phase w/o any subsequent fuzzing. First, fuzzing is more random. Second, if triage duration is different in different versions, then they will do different amount of fuzzing in fixed testbed time.
*	pkg/ipc: remove ExecOpts	Dmitry Vyukov	2024-05-21	1	-2/+1
\| \| \| \|	Switch to flatrpc.ExecOpts.
*	pkg/ipc: remove ProgInfo	Dmitry Vyukov	2024-05-21	1	-4/+2
\| \| \| \| \| \|	Switch to flatrpc.ProgInfo. Note: this disables syz-runtest and syz-verifier.
*	pkg/ipc: use flatrpc flags	Dmitry Vyukov	2024-05-17	1	-3/+4
\| \| \| \| \| \|	Flatrpc flags are passed in RPC execution requests, so to avoid conversions and duplicate set of flags use flatrpc flags in pkg/ipc directly.
*	pkg/fuzzer/queue: simplify the priority queue	Aleksandr Nogikh	2024-05-16	1	-34/+36
\| \| \| \| \| \|	We don't need the full priority queue functionality anymore. For our purposes it's enough to only enforce the order between the elements of different sub-queues.
*	pkg/fuzzer/queue: refactor DynamicSource	Aleksandr Nogikh	2024-05-16	1	-12/+11
\| \| \| \| \|	Use a simpler implementation. Don't assume the nested Source may be nil.
*	pkg/fuzzer: manipulate ipc.ExecOpts	Aleksandr Nogikh	2024-05-16	1	-26/+26
\| \| \| \|	There's no need in duplicating the signal, coverage, hints flags.
*	pkg/fuzzer/queue: retry inputs from crashed VMs	Aleksandr Nogikh	2024-05-16	1	-0/+10
\| \| \| \| \| \| \| \| \| \|	Mark some requests as Important. The Retry() layer will give them one more chance even if they were not executed due to a VM crash. For now, the only important requests are related to triage, candidates and pkg/vminfo tests. Add tests for retry.go.
*	pkg/runtest: use queue.Request and queue.Result	Aleksandr Nogikh	2024-05-16	1	-1/+5
\| \| \| \|	There's no need to duplicate the execution mechanisms.
*	pkg/vminfo: run programs interactively	Aleksandr Nogikh	2024-05-16	1	-0/+121
\| \| \| \| \| \|	Use the same interfaces as the fuzzer. Now syz-manager no longer needs to treat machine check executions differently.
*	pkg/fuzzer: introduce a request restarter layer	Aleksandr Nogikh	2024-05-16	1	-12/+37
\| \| \| \| \| \|	Make Result statuses more elaborate. Instead of retrying inputs directly in rpc.go, extract this logic to a separate entity in pkg/fuzzer/queue.
*	pkg/fuzzer: use queue layers	Aleksandr Nogikh	2024-05-16	1	-0/+270
	Instead of relying on a fuzzer-internal priority queue, utilize stackable layers of request-generating steps. Move the functionality to a separate pkg/fuzzer/queue package. The pkg/fuzzer/queue package can be reused to add extra processing layers on top of the fuzzing and to combine machine checking and fuzzing execution pipelines.
