* [PATCH] Workaround CAPI subsystem locking issueMichael Buesch2007-02-12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | I think the following patch should go into the kernel, until the ISDN/CAPI guys create the real fix for this issue. The issue is a concurrency issue with some internal CAPI data structure which can crash the kernel. On my FritzCard DSL with the AVM driver it crashes about once a day without this workaround patch. With this workaround patch it's rock-stable (at least on UP, but I don't see why this shouldn't work on SMP as well. But maybe I'm missing something.) This workaround is kind of a sledgehammer which inserts a global lock to wrap around all the critical sections. Of course, this is a scalability issue, if you have many ISDN/CAPI cards. But it prevents a crash. So I vote for this fix to get merged, until people come up with a better solution. Better have a stable kernel that's less scalable, than a crashing and useless kernel. This bug is in the kernel since 2.6.15 (at least).

* [PATCH] EDAC: Add memory scrubbing controls API to coreFrithiof Jensen2007-02-12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This is an attempt of providing an interface for memory scrubbing control in EDAC. This patch modifies the EDAC Core to provide the Interface for memory controller modules to implment. The following things are still outstanding: - K8 is the first implemenation, The patch provide a method of configuring the K8 hardware memory scrubber via the 'mcX' sysfs directory. There should be some fallback to a generic scrubber implemented in software if the hardware does not support scrubbing. Or .. the scrubbing sysfs entry should not be visible at all. - Only works with SDRAM, not cache, The K8 can scrub cache and l2cache also - but I think this is not so useful as the cache is busy all the time (one hopes). One would also expect that cache scrubbing requires hardware support. - Error Handling, I would like that errors are returned to the user in "terms of file system". - Presentation, I chose Bandwidth in Bytes/Second as a representation of the scrubbing rate for the following reasons: I like that the sysfs entries are sort-of textual, related to something that makes sense instead of magical values that must be looked up. "My People" wants "% main memory scrubbed per hour" others prefer "% memory bandwidth used" as representation, "bandwith used" makes it easy to calculate both versions in one-liner scripts. If one later wants to scrub cache, the scaling becomes wierd for K8 changing from "blocks of 64 byte memory" to "blocks of 64 cache lines" to "blocks of 64 bit". Using "bandwidth used" makes sense in all three cases, (I.M.O. anyway ;-). - Discovery, There is no way to discover the possible settings and what they do without reading the code and the documentation. *I* do not know how to make that work in a practical way. - Bugs(??), other tools can set invalid values in the memory scrub control register, those will read back as '-1', requiring the user to reset the scrub rate. This is how *I* think it should be. - Afflicting other areas of code, I made changes to edac_mc.c and edac_mc.h which will show up globally - this is not nice, it would be better that the memory scrubbing fuctionality and interface could be entirely contained within the memory controller it applies to. Frithiof Jensen edac_mc.c and its .h file is a CORE helper module for EDAC driver modules. This provides the abstraction for device specific drivers.

* [PATCH] tty: update the tty layer to work with struct pidEric W. Biederman2007-02-12
| | | | | | | | | | | | | | | | | Of kernel subsystems that work with pids the tty layer is probably the largest consumer. But it has the nice virtue that the assiation with a session only lasts until the session leader exits. Which means that no reference counting is required. So using struct pid winds up being a simple optimization to avoid hash table lookups. In the long term the use of pid_nr also ensures that when we have multiple pid spaces mixed everything will work correctly. Signed-off-by: Eric W.

* [PATCH] pid: replace is_orphaned_pgrp with is_current_pgrp_orphanedEric W. Biederman2007-02-12
| | | | | | | | | | | | | | | | | | | Every call to is_orphaned_pgrp passed in process_group(current) which is racy with respect to another thread changing our process group. It didn't bite us because we were dealing with integers and the worse we would get would be a stale answer. In switching the checks to use struct pid to be a little more efficient and prepare the way for pid namespaces this race became apparent. So I simplified the calls to the more specialized is_current_pgrp_orphaned so I didn't have to worry about making logic changes to avoid the race. Signed-off-by: Eric W.

* [PATCH] pid: make session_of_pgrp use struct pid instead of pid_tEric W. Biederman2007-02-12
| | | | | | | | | | | | | | | | | | | | | | | | | To properly implement a pid namespace I need to deal exclusively in terms of struct pid, because pid_t values become ambiguous. To this end session_of_pgrp is transformed to take and return a struct pid pointer. To avoid the need to worry about reference counting I now require my caller to hold the appropriate locks. Leaving callers repsonsible for increasing the reference count if they need access to the result outside of the locks. Since session_of_pgrp currently only has one caller and that caller simply uses only test the result for equality with another process group, the locking change means I don't actually have to acquire the tasklist_lock at all. tiocspgrp is also modified to take and release the lock. The logic there is a little more complicated but nothing I won't need when I convert pgrp of a tty to a struct pid pointer. Signed-off-by: Eric W.

* [PATCH] tty: make __proc_set_tty staticEric W. Biederman2007-02-12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The aim of this patch set is to start wrapping up the struct pid conversions. As such this patchset culminates with the removal of kill_pg, kill_pg_info, __kill_pg_info, do_each_task_pid, and while_each_task_pid. kill_proc, daemonize, and kernel_thread are still in my sights but there is still work to get to them. The first three are basic cleanups around disassociate_ctty, while working on converting it I found several issues. tty_old_pgrp can be a tricky concept to wrap your head around. 1 tty: Make __proc_set_tty static. 2 tty: Clarify disassociate_ctty 3 tty: Fix the locking for signal->session in disassociate_ctty These just stop using the old helper functions. 4 signal: Use kill_pgrp not kill_pg in the sunos compatibility code. 5 signal: Rewrite kill_something_info so it uses newer helpers. Then the grind to convert the tty layer and all of it's helper functions to struct pid. 6 pid: Make session_of_pgrp use struct pid instead of pid_t. 7 pid: Use struct pid for talking about process groups in exit.c 8 pid: Replace is_orphaned_pgrp with is_current_pgrp_orphaned 9 tty: Update the tty layer to work with struct pid. A final helper function update. 10 pid: Replace do/while_each_task_pid with do/while_each_pid_task And the removal of the functions that are now unused. 11 pid: Remove now unused do_each_task_pid and while_each_task_pid 12 pid: Remove the now unused kill_pg kill_pg_info and __kill_pg_info All of these should be fairly simple and to the point. This patch: Currently all users of __proc_set_tty are in tty_io.c so make the function static. Signed-off-by: Eric W.

* [PATCH] RTC gets sysfs wakealarm attributeDavid Brownell2007-02-12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This adds a new "wakealarm" sysfs attribute to RTC class devices which support alarm operations and are wakeup-capable: - It reads as either empty, or the scheduled alarm time as seconds since the POSIX epoch. (That time may already have passed, since nothing currently enforces one-shot alarm semantics.) - It can be written with an alarm time in the future, again seconds since the POSIX epoch, which enables the alarm. - It can be written with an alarm time not in the future (such as 0, the start of the POSIX epoch) to disable the alarm. Usage examples (some need GNU date) after "cd /sys/class/rtc/rtcN": alarm after 10 minutes: # echo $(( $(cat since_epoch) + 10 * 60 )) > wakealarm alarm tuesday evening 10pm: # date -d '10pm tuesday' "+%s" > wakealarm disable alarm: # echo 0 > wakealarm This resembles the /proc/acpi/alarm file in that nothing happens when the alarm triggers ... except possibly waking the system from sleep. It's also like that in a nasty way: not much can be done to prevent one task from clobbering another task's alarm settings. It differs from that file in that there's no in-kernel date parser. Note that a few RTCs ignore rtc_wkalrm.enabled when setting alarms, or aren't set up correctly, so they won't yet behave with this attribute.

* [PATCH] Char: timers cleanupJiri Slaby2007-02-12
| | | | | | | | | | | | | | | | | | | | | - Use timer macros to set function and data members and to modify expiration time. - Use DEFINE_TIMER for global timers and do not init them at run-time in these cases. - del_timer_sync is common in most cases -- we want to wait for timer function if it's still running.
