b5032a5 Jeff Dike 14 July 2006, 19:52:23 UTC [PATCH] UML - fix utsname build breakage Some -mm-only material leaked into a patch destined for mainline, and I didn't notice. This was the replacement of system_utsname with utsname() that's required by the uts namespace patch. This patch reverts those changes (which are correct in -mm) so that mainline UML builds again.

6d76fa5 Linus Torvalds 15 July 2006, 19:26:45 UTC Don't allow chmod() on the /proc/<pid>/ files This just turns off chmod() on the /proc/<pid>/ files, since there is no good reason to allow it, and had we disallowed it originally, the nasty /proc race exploit wouldn't have been possible. The other patches already fixed the problem chmod() could cause, so this is really just some final mop-up.. This particular version is based off a patch by Eugene and Marcel which had much better naming than my original equivalent one.

52393cc Steven Rostedt 14 July 2006, 20:05:03 UTC [PATCH] remove set_wmb - arch removal set_wmb should not be used in the kernel because it just confuses the code more and has no benefit. Since it is not currently used in the kernel this patch removes it so that new code does not include it. All archs define set_wmb(var, value) to do { var = value; wmb(); } while(0) except ia64 and sparc which use a mb() instead. But this is still moot since it is not used anyway. Hasn't been tested on any archs but x86 and x86_64 (and only compiled tested) Signed-off-by: Steven Rostedt <rostedt@goodmis.org> Signed-off-by: Linus Torvalds <torvalds@osdl.org> 15 July 2006, 04:56:14 UTC

bb12999 Shailabh Nagar 14 July 2006, 07:24:47 UTC [PATCH] Remove down_write() from taskstats code invoked on the exit() path In send_cpu_listeners(), which is called on the exit path, a down_write() was protecting operations like skb_clone() and genlmsg_unicast() that do GFP_KERNEL allocations. If the oom-killer decides to kill tasks to satisfy the allocations,the exit of those tasks could block on the same semphore. The down_write() was only needed to allow removal of invalid listeners from the listener list. The patch converts the down_write to a down_read and defers the removal to a separate critical region. This ensures that even if the oom-killer is called, no other task's exit is blocked as it can still acquire another down_read. Thanks to Andrew Morton & Herbert Xu for pointing out the oom related pitfalls, and to Chandra Seetharaman for suggesting this fix instead of using something more complex like RCU.

f9fd891 Shailabh Nagar 14 July 2006, 07:24:47 UTC [PATCH] per-task delay accounting taskstats interface: control exit data through cpumasks On systems with a large number of cpus, with even a modest rate of tasks exiting per cpu, the volume of taskstats data sent on thread exit can overflow a userspace listener's buffers. One approach to avoiding overflow is to allow listeners to get data for a limited and specific set of cpus. By scaling the number of listeners and/or the cpus they monitor, userspace can handle the statistical data overload more gracefully. In this patch, each listener registers to listen to a specific set of cpus by specifying a cpumask. The interest is recorded per-cpu. When a task exits on a cpu, its taskstats data is unicast to each listener interested in that cpu. Thanks to Andrew Morton for pointing out the various scalability and general concerns of previous attempts and for suggesting this design.

c892436 Shailabh Nagar 14 July 2006, 07:24:46 UTC [PATCH] per-task delay accounting: avoid send without listeners Don't send taskstats (per-pid or per-tgid) on thread exit when no one is listening for such data. Currently the taskstats interface allocates a structure, fills it in and calls netlink to send out per-pid and per-tgid stats regardless of whether a userspace listener for the data exists (netlink layer would check for that and avoid the multicast). As a result of this patch, the check for the no-listener case is performed early, avoiding the redundant allocation and filling up of the taskstats structures.

ad4ecbc Shailabh Nagar 14 July 2006, 07:24:44 UTC [PATCH] delay accounting taskstats interface send tgid once Send per-tgid data only once during exit of a thread group instead of once with each member thread exit. Currently, when a thread exits, besides its per-tid data, the per-tgid data of its thread group is also sent out, if its thread group is non-empty. The per-tgid data sent consists of the sum of per-tid stats for all *remaining* threads of the thread group. This patch modifies this sending in two ways: - the per-tgid data is sent only when the last thread of a thread group exits. This cuts down heavily on the overhead of sending/receiving per-tgid data, especially when other exploiters of the taskstats interface aren't interested in per-tgid stats - the semantics of the per-tgid data sent are changed. Instead of being the sum of per-tid data for remaining threads, the value now sent is the true total accumalated statistics for all threads that are/were part of the thread group. The patch also addresses a minor issue where failure of one accounting subsystem to fill in the taskstats structure was causing the send of taskstats to not be sent at all. The patch has been tested for stability and run cerberus for over 4 hours on an SMP.

c757249 Shailabh Nagar 14 July 2006, 07:24:40 UTC [PATCH] per-task-delay-accounting: taskstats interface Create a "taskstats" interface based on generic netlink (NETLINK_GENERIC family), for getting statistics of tasks and thread groups during their lifetime and when they exit. The interface is intended for use by multiple accounting packages though it is being created in the context of delay accounting. This patch creates the interface without populating the fields of the data that is sent to the user in response to a command or upon the exit of a task. Each accounting package interested in using taskstats has to provide an additional patch to add its stats to the common structure.

b04ea3c Eric Paris 14 July 2006, 07:24:33 UTC [PATCH] Fix security check for joint context= and fscontext= mount options After some discussion on the actual meaning of the filesystem class security check in try context mount it was determined that the checks for the context= mount options were not correct if fscontext mount option had already been used. When labeling the superblock we should be checking relabel_from and relabel_to. But if the superblock has already been labeled (with fscontext) then context= is actually labeling the inodes, and so we should be checking relabel_from and associate.

c259cc2 Roland Dreier 14 July 2006, 07:24:23 UTC [PATCH] Convert idr's internal locking to _irqsave variant Currently, the code in lib/idr.c uses a bare spin_lock(&idp->lock) to do internal locking. This is a nasty trap for code that might call idr functions from different contexts; for example, it seems perfectly reasonable to call idr_get_new() from process context and idr_remove() from interrupt context -- but with the current locking this would lead to a potential deadlock. The simplest fix for this is to just convert the idr locking to use spin_lock_irqsave(). In particular, this fixes a very complicated locking issue detected by lockdep, involving the ib_ipoib driver's priv->lock and dev->_xmit_lock, which get involved with the ib_sa module's query_idr.lock.

c38c8db Anil Keshavamurthy 14 July 2006, 07:23:57 UTC [PATCH] ia64: race flushing icache in COW path There is a race condition that showed up in a threaded JIT environment. The situation is that a process with a JIT code page forks, so the page is marked read-only, then some threads are created in the child. One of the threads attempts to add a new code block to the JIT page, so a copy-on-write fault is taken, and the kernel allocates a new page, copies the data, installs the new pte, and then calls lazy_mmu_prot_update() to flush caches to make sure that the icache and dcache are in sync. Unfortunately, the other thread runs right after the new pte is installed, but before the caches have been flushed. It tries to execute some old JIT code that was already in this page, but it sees some garbage in the i-cache from the previous users of the new physical page. Fix: we must make the caches consistent before installing the pte. This is an ia64 only fix because lazy_mmu_prot_update() is a no-op on all other architectures.

de45921 Kirill Korotaev 14 July 2006, 07:23:49 UTC [PATCH] struct file leakage 2.6.16 leaks like hell. While testing, I found massive leakage (reproduced in openvz) in: *filp *size-4096 And 1 object leaks in *size-32 *size-64 *size-128 It is the fix for the first one. filp leaks in the bowels of namei.c. Seems, size-4096 is file table leaking in expand_fdtables. I have no idea what are the rest and why they show only accompanying another leaks. Some debugging structs?

27b437c Herbert Xu 14 July 2006, 02:26:39 UTC [NET]: Update frag_list in pskb_trim When pskb_trim has to defer to ___pksb_trim to trim the frag_list part of the packet, the frag_list is not updated to reflect the trimming. This will usually work fine until you hit something that uses the packet length or tail from the frag_list. Examples include esp_output and ip_fragment. Another problem caused by this is that you can end up with a linear packet with a frag_list attached. It is possible to get away with this if we audit everything to make sure that they always consult skb->len before going down onto frag_list. In fact we can do the samething for the paged part as well to avoid copying the data area of the skb. For now though, let's do the conservative fix and update frag_list. Many thanks to Marco Berizzi for helping me to track down this bug. This 4-year old bug took 3 months to track down.
