8ba8e95 Kalin KOZHUHAROV 31 March 2006, 23:41:22 UTC Fix comments: s/granuality/granularity/ I was grepping through the code and some `grep ganularity -R .` didn't catch what I thought. Then looking closer I saw the term "granuality" used in only four places (in comments) and granularity in many more places describing the same idea. Some other facts: dictionary.com does not know such a word define:granuality on google is not found (and pages for granuality are mostly related to patches to the kernel) it has not been discussed as a term on LKML, AFAICS (=Can Search) To be consistent, I think granularity should be used everywhere.

e9917a0 Steve French 31 March 2006, 21:22:00 UTC [CIFS] Incorrect signature sent on SMB Read Fixes Samba bug 3621 and kernel.org bug 6147 For servers which require SMB/CIFS packet signing, we were sending the wrong signature (all zeros) on SMB Read request. The new cifs routine to do signatures across an iovec was not complete - and SMB Read, unlike the new SMBWrite2, did not fall back to the older routine (ie use SendReceive vs. the more efficient SendReceive2 ie used the older cifs_sign_smb vs. the disabled cifs_sign_smb2) for calculating signatures. This finishes up cifs_sign_smb2/cifs_calc_signature2 so that the callers of SendReceive2 can get SMB/CIFS packet signatures. Now that cifs_sign_smb2 is supported, we could start using it in the write path but this smaller fix does not include the change to use SMBWrite2 when signatures are required (which when enabled will make more Writes more efficient and alloc less memory). Currently Write2 is only used when signatures are not required at the moment but after more testing we will enable that as well). Thanks to James Slepicka and Sam Flory for initial investigation.

108b42b David Howells 31 March 2006, 15:00:29 UTC [PATCH] Document Linux's memory barriers [try #7] The attached patch documents the Linux kernel's memory barriers. I've updated it from the comments I've been given. The per-arch notes sections are gone because it's clear that there are so many exceptions, that it's not worth having them. I've added a list of references to other documents. I've tried to get rid of the concept of memory accesses appearing on the bus; what matters is apparent behaviour with respect to other observers in the system. Interrupts barrier effects are now considered to be non-existent. They may be there, but you may not rely on them. I've added a couple of definition sections at the top of the document: one to specify the minimum execution model that may be assumed, the other to specify what this document refers to by the term "memory". I've made greater mention of the use of mmiowb(). I've adjusted the way in which caches are described, and described the fun that can be had with cache coherence maintenance being unordered and data dependency not being necessarily implicit. I've described (smp_)read_barrier_depends(). I've rearranged the order of the sections, so that memory barriers are discussed in abstract first, and then described the memory barrier facilities available on Linux, before going on to more real-world discussions and examples. I've added information about the lack of memory barriering effects with atomic ops and bitops. I've added information about control dependencies. I've added more diagrams to illustrate caching interactions between CPUs.

6ca0176 Richard Purdie 31 March 2006, 10:31:49 UTC [PATCH] backlight: Backlight Class Improvements Backlight class attributes are currently easy to implement incorrectly. Moving certain handling into the backlight core prevents this whilst at the same time makes the drivers simpler and consistent. The following changes are included: The brightness attribute only sets and reads the brightness variable in the backlight_properties structure. The power attribute only sets and reads the power variable in the backlight_properties structure. Any framebuffer blanking events change a variable fb_blank in the backlight_properties structure. The backlight driver has only two functions to implement. One function is called when any of the above properties change (to update the backlight brightness), the second is called to return the current backlight brightness value. A new attribute "actual_brightness" is added to return this brightness as determined by the driver having combined all the above factors (and any driver/device specific factors). Additionally, the backlight core takes care of checking the maximum brightness is not exceeded and of turning off the backlight before device removal. The corgi backlight driver is updated to reflect these changes.

92476d7 Eric W. Biederman 31 March 2006, 10:31:42 UTC [PATCH] pidhash: Refactor the pid hash table Simplifies the code, reduces the need for 4 pid hash tables, and makes the code more capable. In the discussions I had with Oleg it was felt that to a large extent the cleanup itself justified the work. With struct pid being dynamically allocated meant we could create the hash table entry when the pid was allocated and free the hash table entry when the pid was freed. Instead of playing with the hash lists when ever a process would attach or detach to a process. For myself the fact that it gave what my previous task_ref patch gave for free with simpler code was a big win. The problem is that if you hold a reference to struct task_struct you lock in 10K of low memory. If you do that in a user controllable way like /proc does, with an unprivileged but hostile user space application with typical resource limits of 1000 fds and 100 processes I can trigger the OOM killer by consuming all of low memory with task structs, on a machine wight 1GB of low memory. If I instead hold a reference to struct pid which holds a pointer to my task_struct, I don't suffer from that problem because struct pid is 2 orders of magnitude smaller. In fact struct pid is small enough that most other kernel data structures dwarf it, so simply limiting the number of referring data structures is enough to prevent exhaustion of low memory. This splits the current struct pid into two structures, struct pid and struct pid_link, and reduces our number of hash tables from PIDTYPE_MAX to just one. struct pid_link is the per process linkage into the hash tables and lives in struct task_struct. struct pid is given an indepedent lifetime, and holds pointers to each of the pid types. The independent life of struct pid simplifies attach_pid, and detach_pid, because we are always manipulating the list of pids and not the hash table. In addition in giving struct pid an indpendent life it makes the concept much more powerful. Kernel data structures can now embed a struct pid * instead of a pid_t and not suffer from pid wrap around problems or from keeping unnecessarily large amounts of memory allocated.

8c7904a Eric W. Biederman 31 March 2006, 10:31:37 UTC [PATCH] task: RCU protect task->usage A big problem with rcu protected data structures that are also reference counted is that you must jump through several hoops to increase the reference count. I think someone finally implemented atomic_inc_not_zero(&count) to automate the common case. Unfortunately this means you must special case the rcu access case. When data structures are only visible via rcu in a manner that is not determined by the reference count on the object (i.e. tasks are visible until their zombies are reaped) there is a much simpler technique we can employ. Simply delaying the decrement of the reference count until the rcu interval is over. What that means is that the proc code that looks up a task and later wants to sleep can now do: rcu_read_lock(); task = find_task_by_pid(some_pid); if (task) { get_task_struct(task); } rcu_read_unlock(); The effect on the rest of the kernel is that put_task_struct becomes cheaper and immediate, and in the case where the task has been reaped it frees the task immediate instead of unnecessarily waiting an until the rcu interval is over. Cleanup of task_struct does not happen when its reference count drops to zero, instead cleanup happens when release_task is called. Tasks can only be looked up via rcu before release_task is called. All rcu protected members of task_struct are freed by release_task. Therefore we can move call_rcu from put_task_struct into release_task. And we can modify release_task to not immediately release the reference count but instead have it call put_task_struct from the function it gives to call_rcu. The end result: - get_task_struct is safe in an rcu context where we have just looked up the task. - put_task_struct() simplifies into its old pre rcu self. This reorganization also makes put_task_struct uncallable from modules as it is not exported but it does not appear to be called from any modules so this should not be an issue, and is trivially fixed.

390e2ff Eric W. Biederman 31 March 2006, 10:31:33 UTC [PATCH] Make setsid() more robust The core problem: setsid fails if it is called by init. The effect in 2.6.16 and the earlier kernels that have this problem is that if you do a "ps -j 1 or ps -ej 1" you will see that init and several of it's children have process group and session == 0. Instead of process group == session == 1. Despite init calling setsid. The reason it fails is that daemonize calls set_special_pids(1,1) on kernel threads that are launched before /sbin/init is called. The only remaining effect in that current->signal->leader == 0 for init instead of 1. And the setsid call fails. No one has noticed because /sbin/init does not check the return value of setsid. In 2.4 where we don't have the pidhash table, and daemonize doesn't exist setsid actually works for init. I care a lot about pid == 1 not being a special case that we leave broken, because of the container/jail work that I am doing. - Carefully allow init (pid == 1) to call setsid despite the kernel using its session. - Use find_task_by_pid instead of find_pid because find_pid taking a pidtype is going away.

This change also leads to the converse though, preventing any priority boost from occurring in truly interactive tasks that wait on pipes. Convert the TASK_NONINTERACTIVE flag to set sleep_type to SLEEP_NONINTERACTIVE which will allow a linear bonus to priority based on sleep time thus allowing interactive tasks to get high priority if they sleep enough.

db1b1fe Jack Steiner 31 March 2006, 10:31:21 UTC [PATCH] sched: reduce overhead of calc_load Currently, count_active_tasks() calls both nr_running() & nr_interruptible(). Each of these functions does a "for_each_cpu" & reads values from the runqueue of each cpu. Although this is not a lot of instructions, each runqueue may be located on different node. Depending on the architecture, a unique TLB entry may be required to access each runqueue. Since there may be more runqueues than cpu TLB entries, a scan of all runqueues can trash the TLB. Each memory reference incurs a TLB miss & refill. In addition, the runqueue cacheline that contains nr_running & nr_uninterruptible may be evicted from the cache between the two passes. This causes unnecessary cache misses. Combining nr_running() & nr_interruptible() into a single function substantially reduces the TLB & cache misses on large systems. This should have no measureable effect on smaller systems. On a 128p IA64 system running a memory stress workload, the new function reduced the overhead of calc_load() from 605 usec/call to 324 usec/call.

75c1d31 Richard Purdie 31 March 2006, 10:31:03 UTC [PATCH] LED: class documentation The LED class/subsystem takes John Lenz's work and extends and alters it to give what I think should be a fairly universal LED implementation. The series consists of several logical units: * LED Core + Class implementation * LED Trigger Core implementation * LED timer trigger (example of a complex trigger) * LED device drivers for corgi, spitz and tosa Zaurus models * LED device driver for locomo LEDs * LED device driver for ARM ixp4xx LEDs * Zaurus charging LED trigger * IDE disk activity LED trigger * NAND MTD activity LED trigger Why? ==== LEDs are really simple devices usually amounting to a GPIO that can be turned on and off so why do we need all this code? On handheld or embedded devices they're an important part of an often limited user interface. Both users and developers want to be able to control and configure what the LED does and the number of different things they'd potentially want the LED to show is large. A subsystem is needed to try and provide all this different functionality in an architecture independent, simple but complete, generic and scalable manner. The alternative is for everyone to implement just what they need hidden away in different corners of the kernel source tree and to provide an inconsistent interface to userspace. Other Implementations ===================== I'm aware of the existing arm led implementation. Currently the new subsystem and the arm code can coexist quite happily. Its up to the arm community to decide whether this new interface is acceptable to them. As far as I can see, the new interface can do everything the existing arm implementation can with the advantage that the new code is architecture independent and much more generic, configurable and scalable. I'm prepared to make the conversion to the LED subsystem (or assist with it) if appropriate. Implementation Details ====================== I've stripped a lot of code out of John's original LED class. Colours were removed as LED colour is now part of the device name. Multiple colours are to be handled as multiple led devices. This means you get full control over each colour. I also removed the LED hardware timer code as the generic timer isn't going to add much overhead and is just as useful. I also decided to have the LED core track the current LED status (to ease suspend/resume handling) removing the need for brightness_get implementations in the LED drivers. An underlying design philosophy is simplicity. The aim is to keep a small amount of code giving as much functionality as possible. The major new idea is the led "trigger". A trigger is a source of led events. Triggers can either be simple or complex. A simple trigger isn't configurable and is designed to slot into existing subsystems with minimal additional code. Examples are the ide-disk, nand-disk and zaurus-charging triggers. With leds disabled, the code optimises away. Examples are nand-disk and ide-disk. Complex triggers whilst available to all LEDs have LED specific parameters and work on a per LED basis. The timer trigger is an example. You can change triggers in a similar manner to the way an IO scheduler is chosen (via /sys/class/leds/somedevice/trigger). So far there are only a handful of examples but it should easy to add further LED triggers without too much interference into other subsystems. Known Issues ============ The LED Trigger core cannot be a module as the simple trigger functions would cause nightmare dependency issues. I see this as a minor issue compared to the benefits the simple trigger functionality brings. The rest of the LED subsystem can be modular. Some leds can be programmed to flash in hardware. As this isn't a generic LED device property, I think this should be exported as a device specific sysfs attribute rather than part of the class if this functionality is required (eg. to keep the led flashing whilst the device is suspended). Future Development ================== At the moment, a trigger can't be created specifically for a single LED. There are a number of cases where a trigger might only be mappable to a particular LED. The addition of triggers provided by the LED driver should cover this option and be possible to add without breaking the current interface. A CPU activity trigger similar to that found in the arm led implementation should be trivial to add. This patch: Add some brief documentation of the design decisions behind the LED class and how it appears to users.

993dfa8 Trond Myklebust 31 March 2006, 10:30:55 UTC [PATCH] fs/locks.c: Fix sys_flock() race sys_flock() currently has a race which can result in a double free in the multi-thread case. Thread 1 Thread 2 sys_flock(file, LOCK_EX) sys_flock(file, LOCK_UN) If Thread 2 removes the lock from inode->i_lock before Thread 1 tests for list_empty(&lock->fl_link) at the end of sys_flock, then both threads will end up calling locks_free_lock for the same lock. Fix is to make flock_lock_file() do the same as posix_lock_file(), namely to make a copy of the request, so that the caller can always free the lock. This also has the side-effect of fixing up a reference problem in the lockd handling of flock.

e4e364e Paul Jackson 31 March 2006, 10:30:52 UTC [PATCH] cpuset: memory migration interaction fix Fix memory migration so that it works regardless of what cpuset the invoking task is in. If a task invoked a memory migration, by doing one of: 1) writing a different nodemask to a cpuset 'mems' file, or 2) writing a tasks pid to a different cpuset's 'tasks' file, where the cpuset had its 'memory_migrate' option turned on, then the allocation of the new pages for the migrated task(s) was constrained by the invoking tasks cpuset. If this task wasn't in a cpuset that allowed the requested memory nodes, the memory migration would happen to some other nodes that were in that invoking tasks cpuset. This was usually surprising and puzzling behaviour: Why didn't the pages move? Why did the pages move -there-? To fix this, temporarilly change the invoking tasks 'mems_allowed' task_struct field to the nodes the migrating tasks is moving to, so that new pages can be allocated there.
