Török Edvin	669623d5a6	Fix computation of type sizes in interpreter. ... It was not computing the size of structs. Bug: all bytecodes that had structs on the stack failed with internal out-of-bounds errors. Workaround: compiler will need to avoid putting structs on stack, or do so only for FLEVEL == 0.96.2	16 years ago
Török Edvin	0d4c99465e	Add the builtin bytecode.	16 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.	16 years ago
Török Edvin	927d054838	Add engine param to bytecode, and remove dconf from _init.	16 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.	16 years ago
Tomasz Kojm	ffa9b06093	sigtool: print match count and offsets in --test-sigs mode (bb#2054) ... IMPORTANT NOTE: --test-sigs now only works against the final target file (after all processing, normalization, etc. for which the tested signature was directly created)	16 years ago
Török Edvin	5475ec2a72	Don't attempt to allocate 0 bytes (bb #2042).	16 years ago
Török Edvin	cbb9db1941	Fix some error path leaks (bb #1990). ... This doesn't actually fix bb #1990 (which is about high memory usage on RHEL6), but fixes some leaks found while investigating that bug.	16 years ago

Török Edvin	e86fe7ea90	Add debug messages about how bytecodes are executed (JIT/interpreter).	16 years ago
Török Edvin	b28845c3de	Fix cli_unlink warnings (bb #1956). ... fd == 0 is used to mark an invalid fd (not fd -1). Test that tempfile is not NULL before calling cli_unlink (that is the cause of the Bad address errors). Also call cli_unlink when a virus is found. This isn't strictly necessary since the file will get removed by the parent's rmdirs(), but there is no point in leaving it behind.	16 years ago
