| * Kernel: Audit Support For The ARM PlatformNathaniel Husted2012-01-171-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This patch provides functionality to audit system call events on the ARM platform. The implementation was based off the structure of the MIPS platform and information in this (http://lists.fedoraproject.org/pipermail/arm/2009-October/000382.html) mailing list thread. The required audit_syscall_exit and audit_syscall_entry checks were added to ptrace using the standard registers for system call values (r0 through r3). A thread information flag was added for auditing (TIF_SYSCALL_AUDIT) and a meta-flag was added (_TIF_SYSCALL_WORK) to simplify modifications to the syscall entry/exit. Now, if either the TRACE flag is set or the AUDIT flag is set, the syscall_trace function will be executed. The prober changes were made to Kconfig to allow CONFIG_AUDITSYSCALL to be enabled. Due to platform availability limitations, this patch was only tested on the Android platform running the modified "android-goldfish-2.6.29" kernel. A test compile was performed using Code Sourcery's cross-compilation toolset and the current linux-3.0 stable kernel. The changes compile without error. I'm hoping, due to the simple modifications, the patch is "obviously correct". Signed-off-by: Nathaniel Husted <nhusted@gmail.com> Signed-off-by: Eric Paris <eparis@redhat.com>
| * audit: only allow tasks to set their loginuid if it is -1Eric Paris2012-01-171-0/+14
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | At the moment we allow tasks to set their loginuid if they have CAP_AUDIT_CONTROL. In reality we want tasks to set the loginuid when they log in and it be impossible to ever reset. We had to make it mutable even after it was once set (with the CAP) because on update and admin might have to restart sshd. Now sshd would get his loginuid and the next user which logged in using ssh would not be able to set his loginuid. Systemd has changed how userspace works and allowed us to make the kernel work the way it should. With systemd users (even admins) are not supposed to restart services directly. The system will restart the service for them. Thus since systemd is going to loginuid==-1, sshd would get -1, and sshd would be allowed to set a new loginuid without special permissions. If an admin in this system were to manually start an sshd he is inserting himself into the system chain of trust and thus, logically, it's his loginuid that should be used! Since we have old systems I make this a Kconfig option. Signed-off-by: Eric Paris <eparis@redhat.com>

| * sched: Introduce primitives to account for CFS bandwidth trackingPaul Turner2011-08-141-0/+12
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | In this patch we introduce the notion of CFS bandwidth, partitioned into globally unassigned bandwidth, and locally claimed bandwidth. - The global bandwidth is per task_group, it represents a pool of unclaimed bandwidth that cfs_rqs can allocate from. - The local bandwidth is tracked per-cfs_rq, this represents allotments from the global pool bandwidth assigned to a specific cpu. Bandwidth is managed via cgroupfs, adding two new interfaces to the cpu subsystem: - cpu.cfs_period_us : the bandwidth period in usecs - cpu.cfs_quota_us : the cpu bandwidth (in usecs) that this tg will be allowed to consume over period above.

|/ | | | | | | | | | | | | This commit eliminates the possibility of running TREE_PREEMPT_RCU when SMP=n and of running TINY_RCU when PREEMPT=y. People who really want these combinations can hand-edit init/Kconfig, but eliminating them as choices for production systems reduces the amount of testing required. It will also allow cutting out a few #ifdefs. Note that running TREE_RCU and TINY_RCU on single-CPU systems using SMP-built kernels is still supported. Signed-off-by: Paul E.

However, CONFIG_CONSTRUCTORS currently defaults to y, with no option to disable it, and CONFIG_GCOV_KERNEL depends on it. Instead, default it to n and have CONFIG_GCOV_KERNEL select it, so that the normal case of CONFIG_GCOV_KERNEL=n will result in CONFIG_CONSTRUCTORS=n.

|/ | | | | | | | | | | | | | | | | | | | | | | | | | The "hostname" tool falls back to setting the hostname to "localhost" if /etc/hostname does not exist. Distribution init scripts have the same fallback. However, if userspace never calls sethostname, such as when booting with init=/bin/sh, or otherwise booting a minimal system without the usual init scripts, the default hostname of "(none)" remains, unhelpfully appearing in various places such as prompts ("root@(none):~#") and logs. Furthermore, "(none)" doesn't typically resolve to anything useful. Make the default hostname configurable. This removes the need for the standard fallback, provides a useful default for systems that never call sethostname, and makes minimal systems that much more useful with less configuration. Distributions could choose to use "localhost" here to avoid the fallback, while embedded systems may wish to use a specific target hostname.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The ns_cgroup is an annoying cgroup at the namespace / cgroup frontier and leads to some problems: * cgroup creation is out-of-control * cgroup name can conflict when pids are looping * it is not possible to have a single process handling a lot of namespaces without falling in a exponential creation time * we may want to create a namespace without creating a cgroup The ns_cgroup was replaced by a compatibility flag 'clone_children', where a newly created cgroup will copy the parent cgroup values. The userspace has to manually create a cgroup and add a task to the 'tasks' file. This patch removes the ns_cgroup as suggested in the following thread: https://lists.linux-foundation.org/pipermail/containers/2009-June/018616.html The 'cgroup_clone' function is removed because it is no longer used. This is a userspace-visible change. Commit 45531757b45c ("cgroup: notify ns_cgroup deprecated") (merged into 2.6.27) caused the kernel to emit a printk warning users that the feature is planned for removal.

CONFIG_KALLSYMS_EXTRA_PASS is really about the build time, not run-time. There is no real need for it to be in Kconfig. It is just an additional work-around which should be used only in rare cases, when someone breaks kallsyms, so Kbuild/Makefile is much better place for this option. 2. Grepping CONFIG_KALLSYMS_EXTRA_PASS shows that many defconfigs have it enabled, probably not because they try to work-around a kallsyms bug, but just because the Kconfig help text is confusing and does not really make it clear that this option should not be used unless except when kallsyms is broken. 3. And since many people have CONFIG_KALLSYMS_EXTRA_PASS enabled in their Kconfig, we do might fail to notice kallsyms bugs in time. E.g., many testers use "make allyesconfig" to test builds, which will enable CONFIG_KALLSYMS_EXTRA_PASS and kallsyms breakage will not be noticed. To address that, this patch: 1. Kills CONFIG_KALLSYMS_EXTRA_PASS 2. Changes Makefile so that people can use "make KALLSYMS_EXTRA_PASS=1" to enable the extra pass if needed. Additionally, they may define KALLSYMS_EXTRA_PASS as an environment variable. 3. By default KALLSYMS_EXTRA_PASS is disabled and if kallsyms has issues, "make" should print a warning and suggest using KALLSYMS_EXTRA_PASS Signed-off-by: Artem Bityutskiy <Artem.Bityutskiy@nokia.com> [mmarek: Removed make help text, is not necessary] Signed-off-by: Michal Marek <mmarek@suse.cz>

Improve the help message and make it clearer that KALLSYMS is enough in the majority of use cases, and KALLSYMS_ALL should really be used very rarely.

With or without it, gcc will miss some obvious code size improvements, and with it enabled gcc will sometimes make choices that aren't good even with high I$ miss ratios. For example, with -Os, gcc on x86 will turn a 20-byte constant memcpy into a "rep movsl". While I sincerely hope that x86 CPU's will some day do a good job at that, they certainly don't do it yet, and the cost is higher than a L1 I$ miss would be. Some day I hope we can re-enable this.

This is enabled by the default-off RCU_BOOST kernel parameter. The priority to which to boost preempted RCU readers is controlled by the RCU_BOOST_PRIO kernel parameter (defaulting to real-time priority 1) and the time to wait before boosting the readers who are blocking a given grace period is controlled by the RCU_BOOST_DELAY kernel parameter (defaulting to 500 milliseconds).

| |/ |/| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This reverts commit 4a5fa3590f09, which did not allow SLUB to be used on architectures that use DISCONTIGMEM without compiling NUMA support without CONFIG_BROKEN also set. The slub panic that it was intended to prevent is addressed by d9b41e0b54fd ("[PARISC] set memory ranges in N_NORMAL_MEMORY when onlined") on parisc so there is no further slub issues with such a configuration. The reverts allows SLUB now to be used on such architectures since there haven't been any reports of additional errors.

| |/ | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Slub makes assumptions about page_to_nid() which are violated by DISCONTIGMEM and !NUMA. This violation results in a panic because page_to_nid() can be non-zero for pages in the discontiguous ranges and this leads to a null return by get_node(). The assertion by the maintainer is that DISCONTIGMEM should only be allowed when NUMA is also defined. However, at least six architectures: alpha, ia64, m32r, m68k, mips, parisc violate this. The panic is a regression against slab, so just mark slub broken in the problem configuration to prevent users reporting these panics.
