* Fix fcntl decodingDmitry V. Levin2014-03-03
| | | | | | | | | | | | | | | | Assume that F_SETLK64, F_SETLKW64, and F_GETLK64 are either defined or not defined altogether. Do not assume that sizeof(off_t) < sizeof(long long) when F_SETLK64 is undefined. This change fixes build with musl libc on x86. * configure.ac: Define SIZEOF_OFF_T. * desc.c (USE_PRINTFLOCK64): New macro. (struct flock64, printflock64): Do not define on X32. (printflock): Replace X32 specific workaround with SIZEOF_OFF_T check. Fix printing off_t members of struct flock. (sys_fcntl): Use USE_PRINTFLOCK64.
* Rewrite signal mask decoding without sigset_tDmitry V. Levin2014-02-27
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The sigset_t provided by libc is not quite convenient. In glibc, sigset_t is an array with space for 1024 bits, which is much more than required: all architectures supported by Linux have only 64 signals except MIPS, which has 128. In bionic libc, LP32 sigset_t is only 4 bytes long, which is less than necessary. With this change, signal mask is decoded without use of intermediate sigset_t structure, which saves us some cpu cycles in case of glibc with its inflated sigset_t, and enables build with libcs where sigset_t is broken. Old implementation used to check each signal number in the given signal mask twice using sigismember(). New implementation is based on popcount and next_set_bit() so it's noticeably faster. * configure.ac: Check for __builtin_popcount. * signal.c: Ensure that NSIG >= 32. (sprintsigmask, sprintsigmask_long, printsigmask): Remove. (popcount32, sprintsigmask_n): New functions. (tprintsigmask_addr, sprintsigmask_val, tprintsigmask_val): New macros. (print_sigset_addr_len, sys_sigsetmask, sys_sigreturn, sys_siggetmask, sys_sigsuspend, sys_sigprocmask, decode_new_sigaction): Update to use new signal mask decoding interface. * tests/sigaction.c (main): Add a test with almost filled signal mask. * tests/sigaction.awk: Update.
* Fix build with Bionic libcDmitry V. Levin2014-02-26

* Check for SA_RESTORER definition in <asm/signal.h>Dmitry V. Levin2014-02-08
| | | | | | | | | | Kernel header <asm/signal.h> cannot be included from regular code because it conflicts with libc headers, but SA_RESTORER is needed in signal.c, so SA_RESTORER value is forwarded from <asm/signal.h> to config.h using a configure check. * configure.ac (ASM_SA_RESTORER): Define if SA_RESTORER is defined in <asm/signal.h>.

* Make SIGEV_THREAD_ID decoding less glibc specificDmitry V. Levin2013-11-12
| | | | | | | | | | | | | SIGEV_THREAD_ID decoding requires access to an internal member of struct sigevent. There seems to be no portable way to do it besides adding a configure check. * configure.ac (AC_CHECK_MEMBERS): Check for struct sigevent._sigev_un._pad and struct sigevent.__pad. * time.c (printsigevent): Use an appropriate struct sigevent member to print thread id. Reported by John Spencer.

* Assume "long long" availabilityDmitry V. Levin2013-11-11
| | | | | | | | Most of the code already uses long long types unconditionally. * configure.ac: Remove the check for long long. * file.c (printstat64): Remove HAVE_LONG_LONG checks, use %llu format string unconditionally.
* Stop using external libaio.h.Denys Vlasenko2013-11-11
| | | | | | | | | | | | | | | This change incorporates a partial copy instead of using external libaio.h. Why? Because we want to properly decode 32-bit aio calls by 64-bit strace. For that, we need more definitions than libaio.h provides. (These defs are not done yet, but will eventually be done). Keeping our local 32-bit compat defs in sync with libaio.h _without seeing libaio structs_ is hard/more bug prone. A smaller benefit is that we don't need libaio installed.

* Add support for Imagination Technologies MetaJames Hogan2013-03-05
| | | | | | | | | | | | | | | | | | | | | | | | | | | | Add support for Imagination Technologies Meta architecture (the architecture/ABI is usually referred to as metag in code). The Meta Linux kernel port is in the process of being upstreamed for v3.9 so it uses generic system call numbers. sys_lookup_dcookie writes a filename to buffer argument, so I've set TF flag. nfsservctl appears to be set to sys_ni_syscall in asm-generic/unistd.h so I've left it blank. truncate64/ftruncate64/pread64/pwrite64/readahead have unaligned 64bit args which are packed tightly on metag, so less arguments on metag. fchdir/llseek takes a file descriptor so s/TF/TD/ sync_file_range has 2 64bit args so uses 6 args, so s/4/6/ timerfd_create/msgget/msgctl/msgrcv/semget/segtimedop/semop/shmget/ shmctl/shmat/shmdt/recvmsg/migrate_pages have different number of args. oldgetrlimit is just getrlimit for metag. add TM flag to various memory syscalls. metag doesn't directly use sys_mmap_pgoff for mmap2. prlimit64/process_vm_readv/process_vm_writev take a pid so add TP flag. fanotify_init doesn't appear to take a file descriptor so remove TD.
