These functions have enough code in them such that they seem like sensible targets for un-inlining. Prior to doing that, this adds the tipc_ prefix to the functions, so that in the event of a panic dump or similar, the subsystem from which the functions come from is immediately clear.

Make a cosmetic change to the name displayed for the broadcast link, to better reflect its true nature. Since TIPC utilizes this link to distribute name table information, in addition to multicast messages sent by user applications, the prior name "multicast-link" is no longer appropriate.

In case of aborting because we reach the maximum amount of memory which can be allocated to message queues per user (RLIMIT_MSGQUEUE), we would try to free the message area twice when bailing out: first by the error handling code itself, and then later when cleaning up the inode through delete_inode().

Some callers (in memcontrol.c) calls css_is_ancestor() without rcu_read_lock. Because css_is_ancestor() has to access RCU protected data, it should be under rcu_read_lock(). This makes css_is_ancestor() itself does safe access to RCU protected area. (At least, "root" can have refcnt==0 if it's not an ancestor of "child". So, we need rcu_read_lock().) Signed-off-by:

Commit ad4ba375 ("memcg: css_id() must be called under rcu_read_lock()") modifies memcontol.c for fixing RCU check message. But Andrew Morton pointed out that the fix doesn't seems sane and it was just for hidining lockdep messages. This is a patch for do proper things. Checking again, all places, accessing without rcu_read_lock, that commit fixies was intentional.... all callers of css_id() has reference count on it. So, it's not necessary to be under rcu_read_lock(). Considering again, we can use rcu_dereference_check for css_id(). We know css->id is valid if css->refcnt > 0. (css->id never changes and freed after css->refcnt going to be 0.) This patch makes use of rcu_dereference_check() in css_id/depth and remove unnecessary rcu-read-lock added by the commit.

Currently page_address_in_vma() compares vma->anon_vma and page_anon_vma(page) for parameter check, but in 2.6.34 a vma can have multiple anon_vmas with anon_vma_chain, so current check does not work. (For anonymous page shared by multiple processes, some verified (page,vma) pairs return -EFAULT wrongly.) We can go to checking all anon_vmas in the "same_vma" chain, but it needs to meet lock requirement. Instead, we can remove anon_vma check safely because page_address_in_vma() assumes that page and vma are already checked to belong to the identical process. Signed-off-by:

Mel Gorman authored
Ordinarily, application using hugetlbfs will create mappings with reserves. For shared mappings, these pages are reserved before mmap() returns success and for private mappings, the caller process is guaranteed and a child process that cannot get the pages gets killed with sigbus. An application that uses MAP_NORESERVE gets no reservations and mmap() will always succeed at the risk the page will not be available at fault time. This might be used for example on very large sparse mappings where the developer is confident the necessary huge pages exist to satisfy all faults even though the whole mapping cannot be backed by huge pages. Unfortunately, if an allocation does fail, VM_FAULT_OOM is returned to the fault handler which proceeds to trigger the OOM-killer. This is unhelpful. Even without hugetlbfs mounted, a user using mmap() can trivially trigger the OOM-killer because VM_FAULT_OOM is returned (will provide example program if desired - it's a whopping 24 lines long). It could be considered a DOS available to an unprivileged user. This patch alters hugetlbfs to kill a process that uses MAP_NORESERVE where huge pages were not available with SIGBUS instead of triggering the OOM killer. This change affects hugetlb_cow() as well. I feel there is a failure case in there, but I didn't create one. It would need a fairly specific target in terms of the faulting application and the hugepage pool size. The hugetlb_no_page() path is much easier to hit but both might as well be closed. Signed-off-by:

Originally, commit d899bf7b ("procfs: provide stack information for threads") attempted to introduce a new feature for showing where the threadstack was located and how many pages are being utilized by the stack. Commit c44972f1 ("procfs: disable per-task stack usage on NOMMU") was applied to fix the NO_MMU case. Commit 89240ba0 ("x86, fs: Fix x86 procfs stack information for threads on 64-bit") was applied to fix a bug in ia32 executables being loaded. Commit 9ebd4eba ("procfs: fix /proc/<pid>/stat stack pointer for kernel threads") was applied to fix a bug which had kernel threads printing a userland stack address. Commit 1306d603 ('proc: partially revert "procfs: provide stack information for threads"') was then applied to revert the stack pages being used to solve a significant performance regression. This patch nearly undoes the effect of all these patches. The reason for reverting these is it provides an unusable value in field 28. For x86_64, a fork will result in the task->stack_start value being updated to the current user top of stack and not the stack start address. This unpredictability of the stack_start value makes it worthless. That includes the intended use of showing how much stack space a thread has. Other architectures will get different values. As an example, ia64 gets 0. The do_fork() and copy_process() functions appear to treat the stack_start and stack_size parameters as architecture specific. I only partially reverted c44972f1 ("procfs: disable per-task stack usage on NOMMU") . If I had completely reverted it, I would have had to change mm/Makefile only build pagewalk.o when CONFIG_PROC_PAGE_MONITOR is configured. Since I could not test the builds without significant effort, I decided to not change mm/Makefile. I only partially reverted 89240ba0 ("x86, fs: Fix x86 procfs stack information for threads on 64-bit") . I left the KSTK_ESP() change in place as that seemed worthwhile. Signed-off-by:
