This is a patch that speeds up statfs. It is very simple - the "overhead" calculation, which takes a huge amount of time for large filesystems, never changes unless the size of the filesystem itself changes. That means we can store it in memory and only recalculate if the filesystem has been resized (almost never). It also fixes a minor problem that we never update the on-disk superblock free blocks/inodes counts until the filesystem is unmounted. While not fatal, we may as well update that on disk when we have the information, and it makes things like debugfs and dumpe2fs report a bit more accurate info. Signed-off-by:

Change cancel_work_sync() and cancel_delayed_work_sync() to return a boolean indicating whether the work was actually cancelled. A zero return value means that the work was not pending/queued. Without that kind of change it is not possible to avoid flush_workqueue() sometimes, see the next patch as an example. Also, this patch unifies both functions and kills the (unlikely) busy-wait loop.

Imho, the current naming of cancel_xxx workqueue functions is very confusing. cancel_delayed_work() cancel_rearming_delayed_work() cancel_rearming_delayed_workqueue() // obsolete cancel_work_sync() This looks as if the first 2 functions differ in "type" of their argument which is not true any longer, nowadays the difference is the behaviour. The semantics of cancel_rearming_delayed_work(dwork) was changed significantly, it doesn't require that dwork rearms itself, and cancels dwork synchronously. Rename it to cancel_delayed_work_sync(). This matches cancel_delayed_work() and cancel_work_sync(). Re-create cancel_rearming_delayed_work() as a simple inline obsolete wrapper, like cancel_rearming_delayed_workqueue(). Signed-off-by:

The UMSDOS filesystem was removed back in 2.6.11, but some tiny bits stuck around. This patch removes the few remaining leftovers. The only things left behind after this are the entries in the CREDITS file and the ioctl number in Documentation/ioctl-number.txt as documentation. This third (hopefully final) version of the patch doesn't edit the arch/um/config.release file, since Jeff Dike pointed out to me that it should die completely, and asked me to remove it from my patch as he'll send in a seperate patch removing the file completely.

The current generic bug implementation has a call to dump_stack() in case a WARN_ON(whatever) gets hit. Since report_bug(), which calls dump_stack(), gets called from an exception handler we can do better: just pass the pt_regs structure to report_bug() and pass it to show_regs() in case of a warning. This will give more debug informations like register contents, etc... In addition this avoids some pointless lines that dump_stack() emits, since it includes a stack backtrace of the exception handler which is of no interest in case of a warning. E.g. on s390 the following lines are currently always present in a stack backtrace if dump_stack() gets called from report_bug(): [<000000000001517a>] show_trace+0x92/0xe8) [<0000000000015270>] show_stack+0xa0/0xd0 [<00000000000152ce>] dump_stack+0x2e/0x3c [<0000000000195450>] report_bug+0x98/0xf8 [<0000000000016cc8>] illegal_op+0x1fc/0x21c [<00000000000227d6>] sysc_return+0x0/0x10 Acked-by:

While working on unshare support for the network namespace I noticed we were putting clone flags in an int. Which is weird because the syscall uses unsigned long and we at least need an unsigned to properly hold all of the unshare flags. So to make the code consistent, this patch updates the code to use unsigned long instead of int for the clone flags in those places where we get it wrong today. Signed-off-by:

One common problem with 32 bit system call and ioctl emulation is the different alignment rules between i386 and 64 bit machines. A number of drivers work around this by marking the compat structures as 'attribute((packed))', which is not the right solution because it breaks all the non-x86 architectures that want to use the same compat code. Hopefully, this patch improves the situation, it introduces two new types, compat_u64 and compat_s64. These are defined on all architectures to have the same size and alignment as the 32 bit version of u64 and s64. Signed-off-by:

This patch enables the unshare of user namespaces. It adds a new clone flag CLONE_NEWUSER and implements copy_user_ns() which resets the current user_struct and adds a new root user (uid == 0) For now, unsharing the user namespace allows a process to reset its user_struct accounting and uid 0 in the new user namespace should be contained using appropriate means, for instance selinux The plan, when the full support is complete (all uid checks covered), is to keep the original user's rights in the original namespace, and let a process become uid 0 in the new namespace, with full capabilities to the new namespace.

Basically, it will allow a process to unshare its user_struct table, resetting at the same time its own user_struct and all the associated accounting. A new root user (uid == 0) is added to the user namespace upon creation. Such root users have full privileges and it seems that theses privileges should be controlled through some means (process capabilities ?) The unshare is not included in this patch. Changes since [try #4]: - Updated get_user_ns and put_user_ns to accept NULL, and get_user_ns to return the namespace. Changes since [try #3]: - moved struct user_namespace to files user_namespace.{c,h} Changes since [try #2]: - removed struct user_namespace* argument from find_user() Changes since [try #1]: - removed struct user_namespace* argument from find_user() - added a root_user per user namespace Signed-off-by: -

Add TTY input auditing, used to audit system administrator's actions. This is required by various security standards such as DCID 6/3 and PCI to provide non-repudiation of administrator's actions and to allow a review of past actions if the administrator seems to overstep their duties or if the system becomes misconfigured for unknown reasons. These requirements do not make it necessary to audit TTY output as well. Compared to an user-space keylogger, this approach records TTY input using the audit subsystem, correlated with other audit events, and it is completely transparent to the user-space application (e.g. the console ioctls still work). TTY input auditing works on a higher level than auditing all system calls within the session, which would produce an overwhelming amount of mostly useless audit events. Add an "audit_tty" attribute, inherited across fork (). Data read from TTYs by process with the attribute is sent to the audit subsystem by the kernel. The audit netlink interface is extended to allow modifying the audit_tty attribute, and to allow sending explanatory audit events from user-space (for example, a shell might send an event containing the final command, after the interactive command-line editing and history expansion is performed, which might be difficult to decipher from the TTY input alone). Because the "audit_tty" attribute is inherited across fork (), it would be set e.g. for sshd restarted within an audited session. To prevent this, the audit_tty attribute is cleared when a process with no open TTY file descriptors (e.g. after daemon startup) opens a TTY. See https://www.redhat.com/archives/linux-audit/2007-June/msg00000.html for a more detailed rationale document for an older version of this patch.

Currently we handle spurious IRQ activity based upon seeing a lot of invalid interrupts, and we clear things back on the base of lots of valid interrupts. Unfortunately in some cases you get legitimate invalid interrupts caused by timing asynchronicity between the PCI bus and the APIC bus when disabling interrupts and pulling other tricks. In this case although the spurious IRQs are not a problem our unhandled counters didn't clear and they act as a slow running timebomb. (This is effectively what the serial port/tty problem that was fixed by clearing counters when registering a handler showed up) It's easy enough to add a second parameter - time. This means that if we see a regular stream of harmless spurious interrupts which are not harming processing we don't go off and do something stupid like disable the IRQ after a month of running. OTOH lockups and performance killers show up a lot more than 10/second [akpm@linux-foundation.org: cleanup] Signed-off-by:

Part two in the O_CLOEXEC saga: adding support for file descriptors received through Unix domain sockets. The patch is once again pretty minimal, it introduces a new flag for recvmsg and passes it just like the existing MSG_CMSG_COMPAT flag. I think this bit is not used otherwise but the networking people will know better. This new flag is not recognized by recvfrom and recv. These functions cannot be used for that purpose and the asymmetry this introduces is not worse than the already existing MSG_CMSG_COMPAT situations. The patch must be applied on the patch which introduced O_CLOEXEC. It has to remove static from the new get_unused_fd_flags function but since scm.c cannot live in a module the function still hasn't to be exported. Here's a test program to make sure the code works.

The problem is as follows: in multi-threaded code (or more correctly: all code using clone() with CLONE_FILES) we have a race when exec'ing. thread #1 thread #2 fd=open() fork + exec fcntl(fd,F_SETFD,FD_CLOEXEC) In some applications this can happen frequently. Take a web browser. One thread opens a file and another thread starts, say, an external PDF viewer. The result can even be a security issue if that open file descriptor refers to a sensitive file and the external program can somehow be tricked into using that descriptor. Just adding O_CLOEXEC support to open() doesn't solve the whole set of problems. There are other ways to create file descriptors (socket, epoll_create, Unix domain socket transfer, etc). These can and should be addressed separately though. open() is such an easy case that it makes not much sense putting the fix off. The test program: #include <errno.h> #include <fcntl.h> #include <stdio.h> #include <unistd.h> #ifndef O_CLOEXEC # define O_CLOEXEC 02000000 #endif int main (int argc, char *argv[]) { int fd; if (argc > 1) { fd = atol (argv[1]); printf ("child: fd = %d\n", fd); if (fcntl (fd, F_GETFD) == 0 || errno != EBADF) { puts ("file descriptor valid in child"); return 1; } return 0; } fd = open ("/proc/self/exe", O_RDONLY | O_CLOEXEC); printf ("in parent: new fd = %d\n", fd); char buf[20]; snprintf (buf, sizeof (buf), "%d", fd); execl ("/proc/self/exe", argv[0], buf, NULL); puts ("execl failed"); return 1; } [kyle@parisc-linux.org: parisc fix] Signed-off-by:
