We were using bit 1 of RTL_USER_PROCESS_PARAMETERS for two different cases:
- rightfully, as a sign to block ctrl-c events from being processed by
handlers (and by default, terminating the process)
- But this was also used to request for the creation of a new process group.
This patch properly separates the two use cases, by using the
ProcessGroupId field in RTL_USER_PROCESS_PARAMETERS (checked that Win10
behaves as this patch in RtlCreateUserProcess wrt.
RTL_USER_PROCESS_PARAMETERS ProcessGroupId usage input/output).
Introduce process_group_id in startup_info_t and use it to pass it to
server. ProcessGroupId field in RTL_USER_PROCESS_PARAMETERS is now properly
set.
Note: this will change some external behavior.
- before this patch, a child process created with Ctrl-C disabled
(ConsoleFlags set), couldn't turn it on as the process was detached
from unix console.
- now, SIGINT handling is moved to kernelbase (and can be turned on/off at
application will),
- when creating a new windows group id, the child will be detached from
unix console, so will no longer receives the SIGINT from ctrl-c in unix
console (if parent was attached to this unix console).

OPEN_MAX is 10240, which is usually lower than the kern.maxfilesperproc sysctl
value. Said value from sysctl works on Mojave to Monterey (and most likely
earlier Mac OS versions, but I can't test). Since Big Sur we can successfully
set the reported rlim_max value.
musl libc doesn't supply any definitions for IPX, such as the SOL_IPX
macro. However, it still provides linux/ipx.h from Linux uAPI header
files if it exists.
Linux kernel wouldn't drop linux/ipx.h from uAPI headers until 5.15,
although IPX support has already been marked obsolete since 2018.
Fix this by not defining HAS_IPX if linux/ipx.h has been included but
nothing defines the SOL_IPX macro.
Status of IPX support from other libcs are noted below:
- bionic: netipx/ipx.h does not exist. linux/ipx.h may or may not
exist. Note that sys/socket.h defines SOL_IPX even if linux/ipx.h is
missing.
- glibc: netipx/ipx.h exists. In this case, Wine assumes IPX support
even if the operating system does not support it in runtime.
- BSD variants: netipx/ipx.h may or may not exist. linux/ipx.h does not
exist. Some BSDs supply SO_DEFAULT_HEADERS instead of SOL_IPX.

CFI directives allow the context that was stored on the stack by
raise_func_trampoline to be used to unwind to any exception handlers as
required when dispatching an exception. However, as the dispatcher may change
its input context in e.g. BTCpuResetToConsistentState and these changes also
need to be used when unwinding, have the trampoline CFI directly refer to the
input context rather than a copy of it.
