Török Edvin	4116c65d1b	Add bytecode API to determine whether running under JIT.	15 years ago
Török Edvin	8a8dbd59ea	bytecode test mode: collect & diff events for JIT and interpreter. ... If execution is different for JIT and interpreter test mode shows error.	15 years ago
Török Edvin	70c222c99c	save lsig counts/offsets (bb #2055).	15 years ago
Török Edvin	762d46e8ea	Fix matchicon bytecode API (bb #2139). ... Now you can call it both from a normal lsig triggered BC, and from a PE hook BC. The normal lsig triggered BC has exe_info (but not PE info) which allows it to invoke the icon matcher API. Also putting ICONGROUP1 into the ldb trigger of the bytecode works.	15 years ago

Török Edvin	dc200c6b19	Add bytecode API for pdf.	15 years ago
Török Edvin	d5ffa2acff	Introduce BC_STARTUP bytecode (bb #2101, #2078). ... This bytecode will be run in interpreter mode on startup: it can disable the JIT, or disable all further bytecodes. There will be a builtin copy of it that is loaded if no BC_STARTUP bytecodes were loaded (like filetypes_int.h and daily.ftm). Only one BC_STARTUP bytecode is accepted, so as soon as bytecode.cvd will contain one, it won't be overridable! This bytecode will replace all the JIT checks (CPU, selinux, pax) etc., and allows to disable the JIT on just specific OS/arch/compiler/etc. combinations. There are too many combinations to have a dconf flag for each. Also fix the bytecode dconf so that the individual JIT_* flags actually work (previously we could disable the entire JIT, or none at all). Also introduce preliminary support for bytecode test mode (we already have auto, jit and interpreter mode, introducing another mode here is easiest). The test mode doesn't actually compare the outputs yet, but it does fail if the JIT is disabled / falls back to interpreter.	15 years ago
Török Edvin	a5a19f4518	bytecode: PaX and selfcheck. ... Detect PaX and fallback to intepreter if needed (bb #2092). Recent PaX versions deny the RWX mapping, but older versions silently change it to RW, which causes the program to die as soon as it tries to execute JITed code. Add selfcheck on startup (bb #2092). This will run a very simple bytecode on startup in both JIT and interpreter mode. The bytecode only calls 1 libclamav API and returns.	15 years ago

Török Edvin	99536a178c	Insert timeout checks directly into the JITed code. ... pthread_cancel is broken on Mac OS X (it only works if the thread you want to kill calls pthread_testcancel, which is never the situation when you need async cancelation). Anyway async cancelation is risky, it may leave bc_ctx in an inconsistent state. So rather than doing using pthread_cancel (or pthread_kill+siglongjmp) just insert the timeout checks into the JITed code directly. These are inserted in each loop, if the loop's tripcount is unknown, or higher than a threshold. They are also inserted after a certain amount of APIcalls are made (even in absence of loops). Note that 'loop' in this sense is not LLVM's notion of a natural loop, it is simply a BB which is reachable both directly and via a backedge. For example this doesn't contain natural loops but contains backedges (and a potential infinite loop): int foo(int a) { int x=4; if (a == 42) goto head2; head: x++; head2: if (a >= 2) { x += 3; goto head; } else if (a >= 0) { x += 9; goto head; } return x; }	15 years ago
