2013-04-05linux-user: Don't omit comma for strace of rt_sigaction()Peter Maydell1-1/+1
Pass the 'last' parameter of print_signal() through to print_raw_param(); this fixes a problem where we weren't printing the comma separator for strace of rt_sigaction() when the signal was an unnamed (ie realtime) one: 6856 rt_sigaction(230xf6fff870,0xf6fff8fc) = 0 Signed-off-by: Peter Maydell <peter.maydell@linaro.org> Signed-off-by: Stefan Hajnoczi <stefanha@redhat.com>

2012-02-02linux-user/strace.c: Correct errno printing for mmap etcPeter Maydell1-5/+4
Correct the printing of errnos for syscalls which are handled via print_syscall_ret_addr (mmap, mmap2, brk, shmat): errnos are returned as negative returned values at this level, not via the host 'errno' variable.

2012-02-02linux-user: fix QEMU_STRACE=1 segfaultAlexander Graf1-4/+14
While debugging some issues with QEMU_STRACE I stumbled over segmentation faults that were pretty reproducible. Turns out we tried to treat a normal return value as errno, resulting in an access over array boundaries for the resolution. Fix this by allowing failure to resolve invalid errnos into strings.

2011-02-09linux-user: fix build errors for mmap2-only portsMike Frysinger1-1/+1
The current print_mmap func is only enabled when the target supports the mmap syscall, but both mmap and mmap2 syscalls use it.
