2020-07-13linux-user: Fix Coverity CID 1430271 / CID 1430272Laurent Vivier
In new functions print_ioctl() and print_syscall_ret_ioctl(), we don't check if lock_user() returns NULL and this would cause a segfault in thunk_print(). If lock_user() returns NULL don't call thunk_print() but prints only the value of the (invalid) pointer. Tested with: # cat ioctl.c #include <unistd.h> #include <sys/ioctl.h> int main(void) { int ret; ret = ioctl(STDOUT_FILENO, TCGETS, 0xdeadbeef); ret = ioctl(STDOUT_FILENO, TCSETSF, 0xdeadbeef); return 0; } # QEMU_STRACE= ./ioctl ... 578 ioctl(1,TCGETS,0xdeadbeef) = -1 errno=2 (Bad address) 578 ioctl(1,TCSETSF,0xdeadbeef) = -1 errno=2 (Bad address) ... # QEMU_STRACE= passwd ... 623 ioctl(0,TCGETS,0x3fffed04) = 0 ({}) 623 ioctl(0,TCSETSF,{}) = 0 ...

2020-07-13linux-user: Use EPROTONOSUPPORT for unimplemented netlink protocolsJosh Kunz
Linux uses the EPROTONOSUPPORT error code[1] if the users requests a netlink socket with an unsupported netlink protocol. This change switches linux-user to use the same code as Linux, instead of EPFNOSUPPORT (which AFAIK is just an anachronistic version of EAFNOSUPPORT). Tested by compiling all linux-user targets on x86.

2020-07-13hw/arm/tosa: Encapsulate misc GPIO handling in a devicePeter Maydell
Currently we have a free-floating set of IRQs and a function tosa_out_switch() which handle the GPIO lines on the tosa board which connect to LEDs, and another free-floating IRQ and tosa_reset() function to handle the GPIO line that resets the system. Encapsulate this behaviour in a simple QOM device. This commit fixes Coverity issue CID 1421929 (which pointed out that the 'outsignals' in tosa_gpio_setup() were leaked), because it removes the use of the qemu_allocate_irqs() API from this code entirely.

GCC supports "#pragma GCC diagnostic" since version 4.6, and Clang seems to support it, too, since its early versions 3.x. That means that our minimum required compiler versions all support this pragma already and we can remove the test from configure and all the related #ifdefs in the code. Reviewed-by: Daniel P.

In 45222b9a90, I fixed a broken check for rcu_enable_atfork introduced in d6919e4cb6. I added a call to rcu_enable_atfork after the call to qemu_init in fuzz.c, but forgot to include the corresponding header, breaking --enable-fuzzing --enable-werror builds.
