* io: use umoven_or_printaddr_ignore_syserror as umove function in tprint_iov_uptoEugene Syromyatnikov2016-10-281-3/+5
| | | | | | | | | | | | | | | | | | | | | | | This enables printing of iovec arrays even in case of failed syscall (failed syscall doesn't mean that iovec itself is inaccessible and useless). One caveat here is that we should explicitly provide proper IOV_DECODE_* value based on syserror value in case printing is performed on exiting; we can't simply override it to IOV_DECODE_ADDR on exiting when syserror is up, since this may be called by code which tries to print iovec containing local data, which should be perfectly accessible (on the other hand, there are no cases of such behaviour at the moment). Since iovecs themselves are printed even if syscall has failed now, preadv test is updated to reflect this. It is notable, though, that this is the only place where this case is checked. * io.c (tprint_iov_upto): Specify umoven_or_printaddr_ignore_syserror instead of umoven_or_printaddr as umoven_func parameter. (SYS_FUNC(readv), do_preadv): Specify decode_iov parameter value based on syserror(tcp) value. * scsi.c: (print_sg_io_v3_res, print_sg_io_v4_res): Likewise. * tests/preadv.c: Update expected output for the case when preadv with singe-item iovec failed.
* io: handle data_size of -1 as unlimited data in print_iovecEugene Syromyatnikov2016-10-021-2/+4
| | | | | | | | Otherwise it can be depleted and print_iovec starts printing empty strings. * io.c (print_iovec): Interpret c->data_size of -1 as unlimited data and do not decrease it in this case.
* Rename widen_to_ull to zero_extend_signed_to_ullDmitry V. Levin2016-08-231-4/+4
| | | | | | * defs.h (widen_to_ull): Rename to zero_extend_signed_to_ull. All callers changed. * tests/tests.h: Likewise.
* Move SH-specific argument number calculation to getllvalEugene Syromyatnikov2016-08-211-13/+2
| | | | | | | | | | | | This change prevents scattering of ll-related hacks and simplifies pread/pwrite syscalls parsers' logic a bit. * util.c (getllval): Add fixup for arg_no for SuperH when argument number is equal to 3. * io.c (PREAD_OFFSET_ARG): Remove.

| | | | | | | | | | | | | | | | | | | | | Introduce a general socket netlink parser which prints the header and a string for the remaining part of the buffer. It doesn't handle all the netlink flags and types yet because the parser needs more information, this will be implemented later. * net.c (decode_sockbuf): New function. (SYS_FUNC(send), SYS_FUNC(sendto), SYS_FUNC(recv), SYS_FUNC(recvfrom)): Use it instead of printstr. * msghdr.c (print_msghdr): Pass IOV_DECODE_NETLINK to tprint_iov_upto() for netlink sockets. * netlink.c: New file. * Makefile.am (strace_SOURCES): Add it. * defs.h (decode_netlink, getfdproto): New prototypes.

* mips n32: fix preadv/pwritev offset decodingDmitry V. Levin2015-03-031-2/+0
| | | | | | | In mips n32 abi, like in most of 32-bit architectures, offset is passed to preadv/pwritev syscalls using two syscall arguments. * io.c (print_llu_from_low_high_val) [LINUX_MIPSN32]: Remove.
* Fix ILP32 personality preadv/pwritev offset decoding on LP64 architecturesDmitry V. Levin2015-01-241-1/+10
| | | | | | * io.c (print_llu_from_low_high_val) [SIZEOF_LONG == SIZEOF_LONG_LONG && SUPPORTED_PERSONALITIES > 1]: Properly handle the case of current_wordsize < sizeof(long).
* ioctl: add decoding for parametrized command namesGabriel Laskar2015-01-211-7/+10
| | | | | | | | | | | | | | | Some ioctl commands from evdev, hiddev, mixer, uinput, spi, and joystick are parametrized by a size or a number that are variable. This change implements printing of these parametrized ioctl command names. * configure.ac (AC_CHECK_HEADERS): Add linux/input.h. * defs.h (ioctl_decode_number): New prototype. * io.c (sys_ioctl): Use ioctl_decode_number. * ioctl.c (ioctl_decode_number): New function. * xlat/evdev_abs.in: New file. * xlat/evdev_ev.in: New file.

* ioctl: print unrecognized ioctl codes in _IOC(dir,type,nr,size) formatDmitry V. Levin2015-01-211-1/+1
| | | | | | | | * defs.h (ioctl_print_code): New prototype. * ioctl.c: Include xlat/ioctl_dirs.h. (ioctl_print_code): New function. * io.c (sys_ioctl): Use it. * xlat/ioctl_dirs.in: New file.
* Include <sys/uio.h> unconditionallyDmitry V. Levin2014-11-211-8/+1
| | | | | | | | | | | | | | | Since <sys/uio.h> is standardized by POSIX and is present in all available versions of glibc, it's safe to assume that any usable libc implementation provides this header file. * configure.ac (AC_CHECK_HEADERS): Remove sys/uio.h. * io.c: Include <sys/uio.h> unconditionally. (tprint_iov_upto, tprint_iov, sys_readv, sys_writev, print_llu_from_low_high_val, sys_preadv, sys_pwritev): Define unconditionally. * net.c: Include <sys/uio.h> unconditionally. * util.c: Include <sys/uio.h> unconditionally. (dumpiov): Define unconditionally.
* Fix preadv/pwritev offset decoding on ILP32 architecturesDmitry V. Levin2014-08-071-3/+3
| | | | | | | This fixes regression introduced by the previous commit. * io.c (print_llu_from_low_high_val) [SIZEOF_LONG != SIZEOF_LONG_LONG]: Cast argument to unsigned long before casting it to unsigned long long.
* Fix preadv/pwritev offset decoding on bigendian architecturesDmitry V. Levin2014-08-071-4/+24
| | | | | | | | | | | | | | This partially reverts commit 7845a42b39e59e904d01e75e21f7bc7eb6462560. * util.c (printllval): Remove align argument. * defs.h (printllval): Update prototype. (printllval_aligned, printllval_unaligned): Remove. * file.c (sys_readahead, sys_truncate64, sys_ftruncate64, sys_fadvise64, sys_fadvise64_64, sys_sync_file_range, sys_sync_file_range2, sys_fallocate): Replace printllval_aligned call with printllval. * io.c (sys_pread, sys_pwrite): Likewise. (print_llu_from_low_high_val): New function. (sys_preadv, sys_pwritev): Use it instead of printllval_unaligned.
