* [PATCH] replace cad_pid by a struct pidCedric Le Goater2006-10-024-7/+5
| | | | | | | | | | | | | | | | | | | | | | | | | There are a few places in the kernel where the init task is signaled. The ctrl+alt+del sequence is one them. It kills a task, usually init, using a cached pid (cad_pid). This patch replaces the pid_t by a struct pid to avoid pid wrap around problem. The struct pid is initialized at boot time in init() and can be modified through systctl with /proc/sys/kernel/cad_pid [ I haven't found any distro using it ? ] It also introduces a small helper routine kill_cad_pid() which is used where it seemed ok to use cad_pid instead of pid 1.

* [PATCH] rename the provided execve functions to kernel_execveArnd Bergmann2006-10-022-8/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some architectures provide an execve function that does not set errno, but instead returns the result code directly. Rename these to kernel_execve to get the right semantics there. Moreover, there is no reasone for any of these architectures to still provide __KERNEL_SYSCALLS__ or _syscallN macros, so remove these right away.

* [PATCH] Linux Kernel Dump Test ModuleAnkita Garg2006-10-022-1/+344
| | | | | | | | | | | | | | | | | | | | A simple module to test Linux Kernel Dump mechanism. This module uses jprobes to install/activate pre-defined crash points. At different crash points, various types of crashing scenarios are created like a BUG(), panic(), exception, recursive loop and stack overflow. The user can activate a crash point with specific type by providing parameters at the time of module insertion. Please see the file header for usage information. The module is based on the Linux Kernel Dump Test Tool by Fernando <http://lkdtt.sourceforge.net>. This module could be merged with mainline. Jprobes is used here so that the context in which crash point is hit, could be maintained. This implements all the crash points as done by LKDTT except the one in the middle of tasklet_action().

| | | | | | | | | | | | | | | | The problem with remembering a user space process by its pid is that it is possible that the process will exit, pid wrap around will occur. Converting to a struct pid avoid that problem, and paves the way for implementing a pid namespace. Also since usb is the only user of kill_proc_info_as_uid rename kill_proc_info_as_uid to kill_pid_info_as_uid and have the new version take a struct pid. Signed-off-by: Eric W.

* [PATCH] const struct tty_operationsJeff Dike2006-10-0246-46/+47
| | | | | | | | | | | | | | | | | | | | | | | As part of an SMP cleanliness pass over UML, I consted a bunch of structures in order to not have to document their locking. One of these structures was a struct tty_operations. In order to const it in UML without introducing compiler complaints, the declaration of tty_set_operations needs to be changed, and then all of its callers need to be fixed. This patch declares all struct tty_operations in the tree as const. In all cases, they are static and used only as input to tty_set_operations. As an extra check, I ran an i386 allyesconfig build which produced no extra warnings. 53 drivers are affected. I checked the history of a bunch of them, and in most cases, there have been only a handful of maintenance changes in the last six months. serial_core.c was the busiest one that I looked at.

* [PATCH] vt: Make vt_pid a struct pid (making it pid wrap around safe).Eric W. Biederman2006-10-022-4/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | I took a good hard look at the locking and it appears the locking on vt_pid is the console semaphore. Every modified path is called under the console semaphore except reset_vc when it is called from fn_SAK or do_SAK both of which appear to be in interrupt context. In addition I need to be careful because in the presence of an oops the console_sem may be arbitrarily dropped. Which leads me to conclude the current locking is inadequate for my needs. Given the weird cases we could hit because of oops printing instead of introducing an extra spin lock to protect the data and keep the pid to signal and the signal to send in sync, I have opted to use xchg on just the struct pid * pointer instead. Due to console_sem we will stay in sync between vt_pid and vt_mode except for a small window during a SAK, or oops handling. SAK handling should kill any user space process that care, and oops handling we are broken anyway. Besides the worst that can happen is that I try to send the wrong signal. Signed-off-by: Eric W.

This patch does several things. - The variables used are moved into a structure and declared in vt_kern.h - A spinlock is added so we don't have SMP races updating the values. - Instead of raw pid_t value a struct_pid is used to guard against pid wrap around issues, if the daemon to spawn a new console dies.

| | | | | | | | | | | | | | | | | | | | | | | | This lets the at91rm9200 RTC alarm be a system wakeup irq, according to the setting of /sys/devices/platform/at91_rtc/power/wakeup. User code can set the alarm, put the system into a low power mode, and then rely on it waking up no later than the specified moment.

* | [PATCH] RTC class: error checksDavid Brownell2006-10-012-5/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | The rtc_is_valid_tm() routine needs to treat some of the fields it checks as unsigned, to prevent wrongly accepting invalid rtc_time structs; this is the same approach used elsewhere in the RTC code for such tests. Conversely, rtc_proc_show() is missing one invalid-day-of-month test that rtc_is_valid_tm() makes: there is no day zero.

* | [PATCH] RTC class uses subsys_initDavid Brownell2006-10-014-5/+5
| | | | | | | | | | | | | | | | | | | | | | | | | | | | This makes RTC core components use "subsys_init" instead of "module_init", as appropriate for subsystem infrastructure. This is mostly useful for statically linking drivers in other parts of the tree that may provide an RTC interface as a secondary functionality (e.g. part of a multifunction chip); they won't need to worry so much about drivers/Makefile link order.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Small updates to make the RTC class Kconfig text be more informative. This should help folk used to the drivers/char/rtc.c support, or a single RTC, be slightly less surprised by the differences. Also, adds a new RTC_DEBUG option to predefine DEBUG in the framework and its drivers, while debugging. That's getting to be a standard idiom, and it's pretty useful.
