Seperating the addition and update of marks in inotify resulted in a regression in that inotify never gets events. The inotify group mask is always 0. This mask should be updated any time a new mark is added. Signed-off-by: NEric Paris <eparis@redhat.com>

When an event has no pathname, there's no need to pad it with a null byte and therefore generate an inotify_event sized block of zeros. This fixes a regression introduced by commit 0db501bd where my system wouldn't finish booting because some process was being confused by this.

The root cause is a duplicate section name (.text); is this legal? [ Amerigo Wang: "AFAIK, yes." ] However, there's a problem with commit 6d760133 in that if you fail to allocate a mod->sect_attrs (in this case it's null because of the duplication), it still gets used without checking in add_notes_attrs() This should fix it [ This patch leaves other problems, particularly the sections directory, but recent parisc toolchains seem to produce these modules and this prevents a crash and is a minimal change -- RR ] Signed-off-by: NJames Bottomley <James.Bottomley@suse.de> Signed-off-by: NRusty Russell <rusty@rustcorp.com.au> Tested-by: NHelge Deller <deller@gmx.de> Signed-off-by: NLinus Torvalds <torvalds@linux-foundation.org>

Before the rewrite copy_event_to_user always wrote a terqminating '\0' byte to user space after the filename. Since the rewrite that terminating byte was skipped if your filename is exactly a multiple of event_size. Ouch! So add one byte to name_size before we round up and use clear_user to set userspace to zero like /dev/zero does instead of copying the strange nul_inotify_event. I can't quite convince myself len_to_zero will never exceed 16 and even if it doesn't clear_user should be more efficient and a more accurate reflection of what the code is trying to do.

It will also try to free a failed request or an already freed IRQ if 0 was written to the gpio file.

If the BIOS reports an invalid throttling state (which seems to be fairly common after system boot), a reset is done to state T0. Because of a check in acpi_processor_get_throttling_ptc(), the reset never actually gets executed, which results in the error reoccurring on every access of for example /proc/acpi/processor/CPU0/throttling. Add a 'force' option to acpi_processor_set_throttling() to ensure the reset really takes effect. Addresses http://bugzilla.kernel.org/show_bug.cgi?id=13389 This patch, together with the next one, fixes a regression introduced in 2.6.30, listed on the regression list. They have been available for 2.5 months now in bugzilla, but have not been picked up, despite various reminders and without any reason given. Google shows that numerous people are hitting this issue. The issue is in itself relatively minor, but the bug in the code is clear. The patches have been in all my kernels and today testing has shown that throttling works correctly with the patches applied when the system overheats (http://bugzilla.kernel.org/show_bug.cgi?id=13918#c14).

The return value of the get_temp function is not checked when doing a thermal zone update. This may lead to a critical shutdown if get_temp fails and the content of the temp variable is incorrectly set higher than the critical trip point. This has been observed on a system with incorrect ACPI implementation where the corresponding methods were not serialized and therefore sometimes triggered ACPI errors (AE_ALREADY_EXISTS). The following critical shutdowns indicated a temperature of 2097 C, which was obviously wrong. The patch adds a return value check that jumps over all trip point evaluations printing a warning if get_temp fails. The trip points are evaluated again on the next polling interval with successful get_temp execution.

Spotted by Hiroshi Shimamoto who also provided the test-case below. copy_process() uses signal->count as a reference counter, but it is not. This test case #include <sys/types.h> #include <sys/wait.h> #include <unistd.h> #include <stdio.h> #include <errno.h> #include <pthread.h> void *null_thread(void *p) { for (;;) sleep(1); return NULL; } void *exec_thread(void *p) { execl("/bin/true", "/bin/true", NULL); return null_thread(p); } int main(int argc, char **argv) { for (;;) { pid_t pid; int ret, status; pid = fork(); if (pid < 0) break; if (!pid) { pthread_t tid; pthread_create(&tid, NULL, exec_thread, NULL); for (;;) pthread_create(&tid, NULL, null_thread, NULL); } do { ret = waitpid(pid, &status, 0); } while (ret == -1 && errno == EINTR); } return 0; } quickly creates an unkillable task. If copy_process(CLONE_THREAD) races with de_thread() copy_signal()->atomic(signal->count) breaks the signal->notify_count logic, and the execing thread can hang forever in kernel space. Change copy_process() to increment count/live only when we know for sure we can't fail. In this case the forked thread will take care of its reference to signal correctly. If copy_process() fails, check CLONE_THREAD flag. If it it set - do nothing, the counters were not changed and current belongs to the same thread group. If it is not set, ->signal must be released in any case (and ->count must be == 1), the forked child is the only thread in the thread group. We need more cleanups here, in particular signal->count should not be used by de_thread/__exit_signal at all. This patch only fixes the bug.

An mlocked page might lose the isolatation race. This causes the page to clear PG_mlocked while it remains in a VM_LOCKED vma. This means it can be put onto the [in]active list. We can rescue it by using try_to_unmap() in shrink_page_list(). But now, As Wu Fengguang pointed out, vmscan has a bug. If the page has PG_referenced, it can't reach try_to_unmap() in shrink_page_list() but is put into the active list. If the page is referenced repeatedly, it can remain on the [in]active list without being moving to the unevictable list. This patch fixes it.

It's problematic to allow signed element_nr's or total's to be passed as part of the flex array API. flex_array_alloc() allows total_nr_elements to be set to a negative quantity, which is obviously erroneous. flex_array_get() and flex_array_put() allows negative array indices in dereferencing an array part, which could address memory mapped before struct flex_array. The fix is to convert all existing element_nr formals to be qualified as unsigned. Existing checks to compare it to total_nr_elements or the max array size based on element_size need not be changed.

If all array elements fit into the base structure and data is copied using flex_array_put() starting at a non-zero index, flex_array_get() will fail to return the data. This fixes the bug by only checking for NULL parts when all elements do not fit in the base structure when flex_array_get() is used. Otherwise, fa_element_to_part_nr() will always be 0 since there are no parts structures needed and such element may never have been put. Thus, it will remain NULL due to the kzalloc() of the base. Additionally, flex_array_put() now only checks for a NULL part when all elements do not fit in the base structure. This is otherwise unnecessary since the base structure is guaranteed to exist (or we would have already hit a NULL pointer).
