* Fix sys_semtimedop decoding on s390xStanislav Brabec2012-12-15
| | | | | | | | | | The s390 and s390x pass semtimedop arguments differently from other architectures. sys_semtimedop parser was fixed for s390 by commit v4.6-177-ge0f5fd8, and s390x requires the same fix. * linux/ipc.c (sys_semtimedop): Fix timespec decoding on s390x.

* sys_semtimedop: fix timeval argument index in wrapped callStanislav Brabec2012-12-08
| | | | | | | | | | | | | | | | | | | | | | | | Looking at the implementation of wrapped semtimedop() call inside glibc and kernel, I started to believe that timeval should be located in tcp->u_arg[4] and not tcp->u_arg[5]. Fortunately, tcp->u_arg[5] now works correctly as well, due to side effects of decode_ipc_subcall(). declaration in header: int semtimedop(semid, *sops, nsops, *timeout); 0 1 2 3 sys_ipc arguments in glibc on all patforms except s390*: semid, (int) nsops, 0, CHECK_N (sops, nsops), timeout 0 1 2 3 4 We have to use indexes: 0 3 1 4 sys_ipc arguments on s390*: semid, (int) nsops, timeout, sops 0 1 2 3 We have to use indexes: 0 3 1 2 * ipc.c (sys_semtimedop) [!S390]: Fix timeval argument index in indirect_ipccall case.

* Add x32 support to straceH.J. Lu2012-04-16
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | X32 support is added to Linux kernel 3.4. In a nutshell, x32 is x86-64 with 32bit pointers. At system call level, x32 is also identical to x86-64, as shown by many changes like "defined(X86_64) || defined(X32)". The main differerence bewteen x32 and x86-64 is off_t in x32 is long long instead of long. This patch adds x32 support to strace. Tested on Linux/x32. * configure.ac: Support X32. * defs.h: Set SUPPORTED_PERSONALITIES to 3 for X86_64, Set PERSONALITY2_WORDSIZE to 4 for X86_64.

* Fix sys_ipc/sys_semtimedop decoding on s390Heiko Carstens2011-12-01
| | | | | | | | | | | | | | | | | | The s390 kernel sys_ipc system call only takes five arguments instead of six arguments which the common code sys_ipc implementation takes. One of the arguments of the sys_semtimedop subcall is therefore passed in a different register than in the common code implementation. This leads to broken decoding of the timespec argument: semtimedop(0, 0x3ffffb43832, 1, {...}) = -1 EAGAIN Fixed it looks like this: semtimedop(0, 0x3ffffc2c842, 1, {0, 10000000}) = -1 EINTR * linux/ipc.c (sys_semtimedop): Fix timespec decoding on s390.
