2009-10-17perf: Use die() for error cases in perf-probeMasami Hiramatsu
Use die() for exiting perf-probe with errors. This replaces perror_exit(), msg_exit() and fprintf()+exit() with die(), and uses die() in semantic_error(). This also renames 'die' local variables to 'dw_die' for avoiding name confliction.

2009-10-17perf: Check libdwarf APIs for perf probeMasami Hiramatsu
Check libdwarf APIs for perf probe in tools/perf/Makefile. Since dwarf_get_ranges() has been added from libdwarf 20081231 (and it's the newest function used in probe-finder.c), this just checks whether the function is defined.

2009-10-17x86: Add AMD prefetch and 3DNow! opcodes to opcode mapMasami Hiramatsu
Add AMD prefetch and 3DNow! opcode including FEMMS. Since 3DNow! uses the last immediate byte as an opcode extension byte, x86 insn just treats the extenstion byte as an immediate byte instead of a part of opcode (insn_get_opcode() decodes first "0x0f 0x0f" bytes.) Users who are interested in analyzing 3DNow! opcode still can decode it by analyzing the immediate byte.

2009-10-12perf: Add perf probe subcommand, a kprobe-event setup helperMasami Hiramatsu
Add perf probe subcommand that implements a kprobe-event setup helper to the perf command. This allows user to define kprobe events using C expressions (C line numbers, C function names, and C local variables). Usage ----- perf probe [<options>] -P 'PROBEDEF' [-P 'PROBEDEF' ...] -k, --vmlinux <file> vmlinux/module pathname -P, --probe <p|r:[GRP/]NAME FUNC[+OFFS][@SRC]|@SRC:LINE [ARG ...]> probe point definition, where p: kprobe probe r: kretprobe probe GRP: Group name (optional) NAME: Event name FUNC: Function name OFFS: Offset from function entry (in byte) SRC: Source code path LINE: Line number ARG: Probe argument (local variable name or kprobe-tracer argument format is supported.) Changes in v4: - Add _GNU_SOURCE macro for strndup(). Changes in v3: - Remove -r option because perf always be used for online kernel. - Check malloc/calloc results. Changes in v2: - Check synthesized string length. - Rename perf kprobe to perf probe. - Use spaces for separator and update usage comment. - Check error paths in parse_probepoint(). - Check optimized-out variables.

2009-10-12tracing/kprobes: Add $ prefix to special variablesMasami Hiramatsu
Add $ prefix to the special variables(e.g. sa, rv) of kprobe-tracer. This resolves consistency issues between kprobe_events and perf-kprobe. The main goal is to avoid conflicts between local variable names of probed functions, used by perf probe, and special variables used in the kprobe event creation interface (stack values, etc...) and also available from perf probe. ie: we don't want rv (return value) to conflict with a local variable named rv in a probed function.

2009-09-23fs: change sys_truncate length parameter typeHeiko Carstens
For this system call user space passes a signed long length parameter, while the kernel side takes an unsigned long parameter and converts it later to signed long again. This has led to bugs in compat wrappers see e.g. dd90bbd5 "powerpc: Add compat_sys_truncate". The s390 compat wrapper for this functions is broken as well since it also performs zero extension instead of sign extension for the length parameter. In addition if hpa comes up with an automated way of generating compat wrappers it would generate a wrong one here. So change the length parameter from unsigned long to long. Cc: "H.

2009-09-23V3 minixfs: add missing directory type checkingDoug Graham
There are a few places in the Minix FS code where the "inode" field of a minix_dir_entry is used without checking first to see if the dirent is really a minix3_dir_entry. The inode number in a V1/V2 dirent is 16 bits, whereas that in a V3 dirent is 32 bits. Accessing it as a 16 bit field when it really should be accessed as a 32 bit field probably kinda sorta works on a little-endian machine, but leads to some rather odd behaviour on big-endian machines.
