      initialize struct sigevent before timer_create · 9ed415b2
      由 Jean-Christophe Dubois 提交于 
      When qemu is run under valgrind, valgrind shows the following output
on exit:

==3648== 1 errors in context 2 of 2:
==3648== Syscall param timer_create(evp) points to uninitialised byte(s)
==3648==    at 0x54E936A: timer_create (in /lib/librt-2.9.so)
==3648==    by 0x405DCF: dynticks_start_timer (vl.c:1549)
==3648==    by 0x40A966: main (vl.c:1726)
==3648==  Address 0x7fefffb34 is on thread 1's stack
==3648==  Uninitialised value was created by a stack allocation
==3648==    at 0x405D60: dynticks_start_timer (vl.c:1534)

This patch is a simple fix to remove this potential problem.

      Fix NULL alarm_timer pointer at exit · e332340a
      由 Jean-Christophe Dubois 提交于 
      This fixes a SIGSEGV error on qemu exit.

Here is the valgrind output related to this error

==3648== Process terminating with default action of signal 11 (SIGSEGV)
==3648==  Access not within mapped region at address 0x8
==3648==    at 0x40636B: host_alarm_handler (vl.c:1345)
==3648==    by 0x52D807F: (within /lib/libpthread-2.9.so)
==3648==    by 0x5C0A12E: tcsetattr (in /lib/libc-2.9.so)
==3648==    by 0x4DD601: term_exit (qemu-char.c:700)
==3648==    by 0x5B636EC: exit (in /lib/libc-2.9.so)
==3648==    by 0x5B4B5AC: (below main) (in /lib/libc-2.9.so)

This simple fix check for a valid pointer as host_alarm_handler is
also called after alarm_timer is released in the exit path.

      Drop CONFIG_GDBSTUB · 322f9d01
      由 Jan Kiszka 提交于 
      This is no user-flippable switch, and no arch makes use of disabling
gdbstub support. So it's pointless to keep the related #ifdefs and
configure hunks around - and risking breakages like 711c410fdd again.
