* [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).

| | | | | | | | | | | | | | | | | | | | | | This defines a simple and minimalist programming interface for GPIO APIs: - Documentation/gpio.txt ... describes things (read it) - include/asm-arm/gpio.h ... defines the ARM hook, which just punts to <asm/arch/gpio.h> for any implementation - include/asm-generic/gpio.h ... implement "can sleep" variants as calling the normal ones, for systems that don't handle i2c expanders. The immediate need for such a cross-architecture API convention is to support drivers that work the same on AT91 ARM and AVR32 AP7000 chips, which embed many of the same controllers but have different CPUs. However, several other users have been reported, including a driver for a hardware watchdog chip and some handhelds.org multi-CPU button drivers.

* [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: use struct pid for talking about process groups in exitcEric W. Biederman2007-02-12
| | | | | | | | | | | | Modify has_stopped_jobs and will_become_orphan_pgrp to use struct pid based process groups. This reduces the number of hash tables looks ups and paves the way for multiple pid spaces. 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] signal: use kill_pgrp not kill_pg in the sunos compatibility codeEric W. Biederman2007-02-12
| | | | | | | | | | | | | | I am slowly moving to a model where all process killing is struct pid based instead of pid_t based. The sunos compatibility code is one of the last users of the old pid_t based kill_pg in the kernel. By being complete I allow for the future removal of kill_pg from the kernel, which will ensure I don't miss something. Signed-off-by: Eric W.

| | | | | | | | | | | | commit 24ec839c431eb79bb8f6abc00c4e1eb3b8c4d517 while fixing the locking for signal->tty got the locking wrong for signal->session.

* [PATCH] tty: clarify disassociate_cttyEric W. Biederman2007-02-12
| | | | | | | | | | | | | | | The code to look at tty_old_pgrp and send SIGHUP and SIGCONT when it is present only executes when disassociate_ctty is called from do_exit. Make this clear by adding an explict on_exit check, and explicitly setting tty_old_pgrp to 0. In addition fix the locking by reading tty_old_pgrp under the siglock. Signed-off-by: Eric W.
