This series covers strace support for following syscalls:
*truncate() *munlock() *clock_gettimeofday()
*ftruncate() *munlockall() *clock_getitimer()
*getsid() *clock_getres() *clock_setitimer()
*mlock() *clock_gettime()
*mlockall() *clock_settime()
Testing method:
Mini test programs were written that run these syscalls for different
arguments.
Those programs were compiled (sometimes using cross-compilers) for the
following
architectures:
* Intel 64-bit (little endian) (gcc)
* Power pc 32-bit (big endian) (powerpc-linux-gnu-gcc)
* Power pc 64-bit (big endian) (powerpc64-linux-gnu-gcc)
The corresponding native programs were executed with strace, without using
QEMU, on intel (x86_64) host.
All applicable compiled programs were in turn executed with "-strace"
through QEMU and the strace printing results obtained were the same
ones gotten for native execution.
v2:
* added patch that enables 'cpu_env' to be accessible from "strace.c"
* cut and pasted "regpairs_aligned" from 'syscall.c' to 'qemu.h' so
that it can be used for "print_truncate64" and "print_ftruncate64"
* changed flag names from 'TARGET_MLOCKALL_MCL_*' to 'TARGET_MCL_*'
* added target flag value 'TARGET_MCL_ONFAULT' for 'MCL_ONFAULT'
* added 'print_syscall_ret_setitimer' for old value of the interval
timer
* added a function 'print_itimer_type' that prints the interval timer
type
v3:
* added patch that introduces an api that prints enumarted values
with strace
* used this new introduced api to print certain arguments of syscalls
in patch 4
* rebased the series to use the new 'print_syscall_err()'
v4:
* modified 'print_itimerval()' function in 'syscall.c'
