It shouldn't even request that region, > since it's not been allocated! The commit 139ddfca ("ide: move handling of I/O resources out of ide_probe_port()") changed the ordering of hwif->noprobe check vs ide_hwif_request_regions() call (so that we now reserve I/O regions before checking for hwif->noprobe). However ide-generic host driver depended on hwif->noprobe to be set for skipping probing of empty ide_hwifs[] slots. Fix it by passing only indexes of non-empty slots to ide_device_add_all() from ide_generic_init(). Signed-off-by:

Redo the calculation of NR_syscalls since that disappeared from i386 and use a similar mechanism on x86_64. We now figure out the size of the system call table in arch code and stick that in syscall_table_size. arch/um/kernel/skas/syscall.c defines NR_syscalls in terms of that since its the only thing that needs to know how many system calls there are. The old mechananism that was used on x86_64 is gone. arch/um/include/sysdep-i386/syscalls.h got some formatting since I was looking at it. Signed-off-by:

This patch takes care of a problem with the stopping code. The function inside the while condition returns 0 to signify a problem. A problem could be for example a bad command or a bad version of the mconsole client. A bad command would terminate the stopping loop and resume the kernel. This is a problem. A better solution is to make the loop infinite and don't leave it until we are explicitly told to. Signed-off-by:

avoid-overflows-in-kernel-timec.patch makes CONFIG_HZ necessary for a successful build. UML lacks a definition, so this patch adds one. It also changes the hard-wired definition of HZ to CONFIG_HZ.

A couple more DEBUG_SHIRQ fixes. The previous mconsole blocking fix exposed the lack of O_NONBLOCK on the mconsole socket. Also, winch_interrupt started crashing because it is called at irq free time and it tries to dereference tty->driver_data, which has already been set to NULL. I added some error cleanup in mconsole_init while I was there. Cc: "Karol Swietlicki" <magotari@gmail.com> Signed-off-by:

init_irq_signals doesn't need to be called from the context of a new process. It initializes handlers, which are useless in process context. With that call gone, init_irq_signals has only one caller, so it can be inlined into init_new_thread_signals. Signed-off-by:

This patch tidies the signal handling code slightly. pending is renamed to signals_pending for symmetry with signals_enabled. remove_sigstack was unused, so can be deleted. The value of change_sig was never used, so it is now void and the return value is not calculated any more. Signed-off-by:

sig_handler_common_skas needs significant modernization, starting with its name and storage class. There is no need to hide the true type of the sigcontext pointer, so the void * dummy parameter can be replaced with a sigcontext *sc. The array of uml_pt_regs structs used in the page fault case are gone, replaced by a local variable. This is also used in the non-segfault case instead of the copy in the task_struct. Since it's local, the special handling of the is_user flag can go away. There hasn't been any special treatment of SIGUSR1 in ages, so the line that enables it can be deleted. The special treatment of SIGSEGV similarly goes away, but to compensate, SA_NODEFER is added to sa_mask when registering a signal handler. Signed-off-by:

This patch moves sig_handler_common_skas from arch/um/os-Linux/skas/trap.c to its only caller in arch/um/os-Linux/signal.c. trap.c is now empty, so it can be removed. This is code movement only - the significant cleanup needed here is done in the next patch. Signed-off-by:

Kill a process that tries to branch into a stub and execute a system call. There are no security implications here - a system call in a stub is treated the same as a system call anywhere else. But if a process is trying to branch into a stub, either it is trying something nasty or it has gone haywire, so it's a good idea to get rid of it in either case. Signed-off-by:

A bit of defensive programming - during development, it ocassionally happens that a call to init_new_context is missed, resulting in context holding a host pid of zero. When that address space is torn down, destroy_context does a kill(0), which instantly kills the whole UML without any errors whatsoever. This patch add a check for pids less than 2, to also catch 1 and negative pids. Signed-off-by:

Style fixes to arch/um/os/helper.c and tidying up the breakpoint fix a bit. helper.c gets all the usual style fixes - updated copyright all printks get severities Also - errval changes to err in helper_child fixed an obsolete comment run_helper was killing a child process which is guaranteed to be dead or dying anyway Removed the nohang and pname arguments from helper_wait and fixed the declaration and callers. nohang was used only in the slirp driver and I don't think it was needed. I think pname was a bit of overkill in putting out an error message when something goes wrong. Signed-off-by:

signals_enabled and pending have requirements on the order in which they are modified. This used to be done by declaring them volatile and putting an mb() where the ordering requirements were in effect. After getting a better (I hope) understanding of how to do this correctly, the volatile declarations are gone and the mb()'s replaced by barrier()'s. One of the mb()'s was deleted because I see no problematic writes that could be re-ordered past that point. Signed-off-by:
