This series of patches re-introduces the iommu_num_pages function so that it can be used by each architecture specific IOMMU implementations. The series also changes IOMMU implementations for X86, Alpha, PowerPC and UltraSparc.

struct stat / compat_stat is the same on all architectures, so cp_compat_stat should be, too. Turns out it is, except that various architectures have slightly and some high2lowuid/high2lowgid or the direct assignment instead of the SET_UID/SET_GID that expands to the correct one anyway.

With MAX_ARG_STRINGS set to 0x7FFFFFFF, and being passed to 'count()' and compat_count(), it would appear that the current max bounds check of fs/exec.c:394: if(++i > max) return -E2BIG; would never trigger. Since 'i' is of type int, so values would wrap and the function would continue looping. Simple fix seems to be chaning ++i to i++ and checking for '>='.

On sethostname() and setdomainname(), previous information may be retained if it was longer than than the new hostname/domainname. This can be demonstrated trivially by calling sethostname() first with a long name, then with a short name, and then calling uname() to retrieve the full buffer that contains the hostname (and possibly parts of the old hostname), one just has to look past the terminating zero. I don't know if we should really care that much (hence the RFC); the only scenarios I can possibly think of is administrator putting something sensitive in the hostname (or domain name) by accident, and changing it back will not undo the mistake entirely, though it's not like we can recover gracefully from "rm -rf /" either... The other scenario is namespaces (CLONE_NEWUTS) where some information may be unintentionally "inherited" from the previous namespace (a program wants to hide the original name and does clone + sethostname, but some information is still left). I think the patch may be defended on grounds of the principle of least surprise. But I am not adamant :-) (I guess the question now is whether userspace should be able to write embedded NULs into the buffer or not...) At least the observation has been made and the patch has been presented. Signed-off-by: NVegard Nossum <vegard.nossum@gmail.com> Cc: "Eric W. Biederman" <ebiederm@xmission.com> Cc: "Serge E.

Way too often, I have a machine that exhibits some kind of crappy behavior. The CPU looks wedged in the kernel or it is spending way too much system time and I wonder what is responsible. I try to run readprofile. But, of course, Ubuntu doesn't enable it by default. Dang! The reason we boot-time enable it is that it takes a big bufffer that we generally can only bootmem alloc. But, does it hurt to at least try and runtime-alloc it? To use: echo 2 > /sys/kernel/profile Then run readprofile like normal. This should fix the compile issue with allmodconfig.

When a process wants to set the limit of open files to RLIM_INFINITY it gets EPERM even if it has CAP_SYS_RESOURCE capability. For example, BIND does: ... #elif defined(NR_OPEN) && defined(__linux__) /* * Some Linux kernels don't accept RLIM_INFINIT; the maximum * possible value is the NR_OPEN defined in linux/fs.h. */ if (resource == isc_resource_openfiles && rlim_value == RLIM_INFINITY) { rl.rlim_cur = rl.rlim_max = NR_OPEN; unixresult = setrlimit(unixresource, &rl); if (unixresult == 0) return (ISC_R_SUCCESS); } #elif ... If we allow setting RLIMIT_NOFILE to RLIM_INFINITY we increase portability - you don't have to check if OS is linux and then use different schema for limits. The spec says "Specifying RLIM_INFINITY as any resource limit value on a successful call to setrlimit() shall inhibit enforcement of that resource limit." and we're presently not doing that.

It's somewhat unlikely that it happens, but right now a race window between interrupts or machine checks or oopses could corrupt the tainted bitmap because it is modified in a non atomic fashion. Convert the taint variable to an unsigned long and use only atomic bit operations on it. Unfortunately this means the intvec sysctl functions cannot be used on it anymore. It turned out the taint sysctl handler could actually be simplified a bit (since it only increases capabilities) so this patch actually removes code.

When unpacking the cpio into the initramfs, mtimes are not preserved by default. This patch adds an INITRAMFS_PRESERVE_MTIME option that allows mtimes stored in the cpio image to be used when constructing the initramfs. For embedded applications that run exclusively out of the initramfs, this is invaluable: When building embedded application initramfs images, its nice to know when the files were actually created during the build process - that makes it easier to see what files were modified when so we can compare the files that are being used on the image with the files used during the build process. This might help (for example) to determine if the target system has all the updated files you expect to see w/o having to check MD5s etc. In our environment, the whole system runs off the initramfs partition, and seeing the modified times of the shared libraries (for example) helps us find bugs that may have been introduced by the build system incorrectly propogating outdated shared libraries into the image. Similarly, many of the initializion/configuration files in /etc might be dynamically built by the build system, and knowing when they were modified helps us sanity check whether the target system has the "latest" files etc. Finally, we might use last modified times to determine whether a hot fix should be applied or not to the running ramfs.

由 Tejun Heo 提交于
is_sync_wait() is used to distinguish between sync and async waits. Basically sync waits are the ones initialized with init_waitqueue_entry() and async ones with init_waitqueue_func_entry(). The sync/async distinction is used only in prepare_to_wait[_exclusive]() and its only function is to skip setting the current task state if the wait is async. This has a few problems. * No one uses it. None of func_entry users use prepare_to_wait() functions, so the code path never gets executed. * The distinction is bogus. Maybe back when func_entry is used only by aio but it's now also used by epoll and in future possibly by 9p and poll/select. * Taking @state as argument and ignoring it silenly depending on how @wait is initialized is just a bad error-prone API. * It prevents func_entry waits from using wait->private for no good reason. This patch kills is_sync_wait() and the associated code paths from prepare_to_wait[_exclusive](). As there was no user of these code paths, this patch doesn't cause any behavior difference.

Use the '%pF' format to get rid of an "#ifdef DEBUG" and make some printks atomic. This removes the last in-tree uses of print_fn_descriptor_symbol(). I marked print_fn_descriptor_symbol() deprecated and scheduled it for removal next year to give time for out-of-tree modules to be updated. parisc's print_fn_descriptor_symbol() is currently broken there (it needs to dereference the function pointer similar to ia64 and power). This patch shouldn't make anything worse, but it means we need to fix dereference_function_descriptor() instead of print_fn_descriptor_symbol() to get meaningful initcall_debug output.

The kernel.h macro DIV_ROUND_UP performs the computation (((n) + (d) - 1) / (d)) but is perhaps more readable. An extract of the semantic patch that makes this change is as follows: (http://www.emn.fr/x-info/coccinelle/) // <smpl> @haskernel@ @@ #include <linux/kernel.h> @depends on haskernel@ expression n,d; @@ ( - (n + d - 1) / d + DIV_ROUND_UP(n,d) | - (n + (d - 1)) / d + DIV_ROUND_UP(n,d) ) @depends on haskernel@ expression n,d; @@ - DIV_ROUND_UP((n),d) + DIV_ROUND_UP(n,d) @depends on haskernel@ expression n,d; @@ - DIV_ROUND_UP(n,(d)) + DIV_ROUND_UP(n,d) // </smpl> Signed-off-by: NJulia Lawall <julia@diku.dk> Cc: Jack Steiner <steiner@sgi.com> Signed-off-by: NAndrew Morton <akpm@linux-foundation.org> Signed-off-by: NLinus Torvalds <torvalds@linux-foundation.org>
