These patches implement new filtering architecture. Currently supported actions: trace, inject, fault, read, write, raw, abbrev, verbose. Currently supported filters: syscall, fd, path. Changes in filtering language: * Delimiter of action arguments is now ';'. * Supported logical operators: and, or, not. Also C-like forms of these operators are supported: &&, ||, !. * Syscall filter accepts syscalls' set, class or regex with old set description syntax.
Changes since v1: * qualify.c is now splitted in separate commit. Changes since v2: * Fixed segmentation fault in inject/fault parsing. * basic_filters.c (run_fd_filter): Changed returns to true/false. Changes since v3: * Fixed invalid accounting of syscalls for inject/fault actions. * Fixed order of filter actions with same priority. * Refactored inject arguments parsing. * Refactored fd filtering. * Refactored tests for syscall set syntax. * Improved diagnostics of filtering errors. * Rewritten algorithms of parsing for new filtering language. Changes since v4: * Fixes in fd and path filtering. * Added tests for fd filtering. * Syscall tests refactoring is now in a separate commit. * Style and readability fixes. Known issues in v4: * Fd filter returns valid results only if negative fds are not filtered. Changes since v5: * Refactored parsing. * Fixes in fd and path filtering. * Improved diagnostics. * Added stacktrace action. * Style fixes.
