2022-04-21util: simplify write in signal handlerMarc-André Lureau1-16/+2

2021-10-13util/compatfd.c: use libc signalfd wrapper instead of raw syscallKacper Słomiński1-3/+2
This allows the use of native signalfd instead of the sigtimedwait based emulation on systems other than Linux. Signed-off-by: Kacper Słomiński <kacper.slominski72@gmail.com> Message-Id: <20210905011621.200785-1-kacper.slominski72@gmail.com> Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
2021-05-14util/compatfd.c: Replaced a malloc call with g_malloc.Mahmoud Mandour1-6/+2
Replaced a call to malloc() and its respective call to free() with g_malloc() and g_free(). g_malloc() is preferred more than g_try_* functions, which return NULL on error, when the size of the requested allocation is small. This is because allocating few bytes should not be a problem in a healthy system. Otherwise, the system is already in a critical state. Subsequently, removed NULL-checking after g_malloc().

2020-07-13util/compatfd.c: Only include <sys/syscall.h> if CONFIG_SIGNALFDDavid CARLIER1-0/+2
util/compatfd.c includes <sys/syscall.h> so that the CONFIG_SIGNALFD code can use SYS_signalfd. Guard the #include with CONFIG_SIGNALFD to avoid portability issues on hosts like Haiku which do not provide that header file.

2017-03-03cpus: remove ugly cast on sigbus_handlerPaolo Bonzini1-1/+0
The cast is there because sigbus_handler is invoked via sigfd_handler. But it feels just wrong to use struct qemu_signalfd_siginfo in the prototype of a function that is passed to sigaction. Instead, do a simple-minded conversion of qemu_signalfd_siginfo to siginfo_t. Signed-off-by: Paolo Bonzini <pbonzini@redhat.com>
