A while ago Randy Dunlap and Adrian Bunk suggested we simply prevent UP voyager building. I resisted this on the grounds that the nagging was the only thing that was going to cause me to look at this. However, now I think we should probably take this course.

When dumping memory via sysrq-m it is possible to take a bogus NMI watchdog or softlockup watchdog because the dump can take a long time on big memory systems. Occasionally tickle the watchdog when doing the dump. Signed-off-by:

if CONFIG_PAGEALLOC is enabled then X86_FEATURE_PSE is disabled and all the kernel physical RAM pagetables are set up as 4K pages. This is needed so that CONFIG_PAGEALLOC can do finegrained mapping and unmapping of pages. as a side-effect though, the total size of memory allocated as kernel pagetables increases significantly. All these pagetables are allocated via alloc_bootmem_low_pages(), straight out of the lowmem DMA pool. If the system has enough RAM and a large kernel image then almost all of the 16 MB lowmem DMA pool is allocated to the image and to pagetables - leaving no space for __GFP_DMA allocations. this results in drivers failing and the bootup hanging: swapper invoked oom-killer: gfp_mask=0x80d1, order=0, oomkilladj=0 [<4015059f>] out_of_memory+0x17f/0x1c0 [<40151f3c>] __alloc_pages+0x37c/0x3a0 [<40168cd7>] slob_new_page+0x37/0x50 [<40168dff>] slob_alloc+0x10f/0x190 [<40169010>] __kmalloc_node+0x80/0x90 [<405a17e3>] scsi_host_alloc+0x33/0x2c0 [<405a1a82>] scsi_register+0x12/0x60 [<40d5889e>] aha1542_detect+0x9e/0x940 [<405c5ba5>] ultrastor_detect+0x265/0x5f0 [<401352f5>] getnstimeofday+0x35/0xf0 [<40d58751>] init_this_scsi_driver+0x41/0xf0 [<40d0b856>] kernel_init+0x136/0x310 [<40d58710>] init_this_scsi_driver+0x0/0xf0 [<40d0b720>] kernel_init+0x0/0x310 [<40105547>] kernel_thread_helper+0x7/0x10 ======================= the fix is to first allocate from above the DMA pool, and if that fails (for example due to it being a machine with less than 16 MB of RAM), allocate from the DMA pool as a fallback. With this fix applied i was able to boot a PAGEALLOC=y kernel that would hang before. Signed-off-by:

To preserve the DMA pool in CONFIG_DEBUG_PAGEALLOC=y kernels, we'll allocate pagetables from above the 16MB DMA limit, so we'll have to set up boot pagetables to cover 16MB more RAM (worst-case). Signed-off-by:

Fix bugzilla #8679 WARNING: arch/i386/kernel/built-in.o(.data+0x2148): Section mismatch: reference to .init.text: (between 'thermal_throttle_cpu_notifier' and 'mtrr_mutex') comes because struct notifier_block thermal_throttle_cpu_notifier in arch/i386/kernel/cpu/mcheck/therm_throt.c goes in .data section but the notifier callback function itself has been marked __cpuinit which becomes __init == .init.text when HOTPLUG_CPU=n. The warning is bogus because the callback will never be called out if HOTPLUG_CPU=n in the first place (as one can see from kernel/cpu.c, the cpu_chain itself is __cpuinitdata :-) So, let's mark thermal_throttle_cpu_notifier as __cpuinitdata to fix the section mismatch warning.

Implement file posix capabilities. This allows programs to be given a subset of root's powers regardless of who runs them, without having to use setuid and giving the binary all of root's powers. This version works with Kaigai Kohei's userspace tools, found at http://www.kaigai.gr.jp/index.php. For more information on how to use this patch, Chris Friedhoff has posted a nice page at http://www.friedhoff.org/fscaps.html. Changelog: Nov 27: Incorporate fixes from Andrew Morton (security-introduce-file-caps-tweaks and security-introduce-file-caps-warning-fix) Fix Kconfig dependency. Fix change signaling behavior when file caps are not compiled in. Nov 13: Integrate comments from Alexey: Remove CONFIG_ ifdef from capability.h, and use %zd for printing a size_t. Nov 13: Fix endianness warnings by sparse as suggested by Alexey Dobriyan. Nov 09: Address warnings of unused variables at cap_bprm_set_security when file capabilities are disabled, and simultaneously clean up the code a little, by pulling the new code into a helper function. Nov 08: For pointers to required userspace tools and how to use them, see http://www.friedhoff.org/fscaps.html. Nov 07: Fix the calculation of the highest bit checked in check_cap_sanity(). Nov 07: Allow file caps to be enabled without CONFIG_SECURITY, since capabilities are the default. Hook cap_task_setscheduler when !CONFIG_SECURITY. Move capable(TASK_KILL) to end of cap_task_kill to reduce audit messages. Nov 05: Add secondary calls in selinux/hooks.c to task_setioprio and task_setscheduler so that selinux and capabilities with file cap support can be stacked. Sep 05: As Seth Arnold points out, uid checks are out of place for capability code. Sep 01: Define task_setscheduler, task_setioprio, cap_task_kill, and task_setnice to make sure a user cannot affect a process in which they called a program with some fscaps. One remaining question is the note under task_setscheduler: are we ok with CAP_SYS_NICE being sufficient to confine a process to a cpuset? It is a semantic change, as without fsccaps, attach_task doesn't allow CAP_SYS_NICE to override the uid equivalence check. But since it uses security_task_setscheduler, which elsewhere is used where CAP_SYS_NICE can be used to override the uid equivalence check, fixing it might be tough. task_setscheduler note: this also controls cpuset:attach_task. Are we ok with CAP_SYS_NICE being used to confine to a cpuset? task_setioprio task_setnice sys_setpriority uses this (through set_one_prio) for another process. Need same checks as setrlimit Aug 21: Updated secureexec implementation to reflect the fact that euid and uid might be the same and nonzero, but the process might still have elevated caps. Aug 15: Handle endianness of xattrs. Enforce capability version match between kernel and disk. Enforce that no bits beyond the known max capability are set, else return -EPERM. With this extra processing, it may be worth reconsidering doing all the work at bprm_set_security rather than d_instantiate. Aug 10: Always call getxattr at bprm_set_security, rather than caching it at d_instantiate.

James Morris authored
Convert LSM into a static interface, as the ability to unload a security module is not required by in-tree users and potentially complicates the overall security architecture. Needlessly exported LSM symbols have been unexported, to help reduce API abuse. Parameters for the capability and root_plug modules are now specified at boot. The SECURITY_FRAMEWORK_VERSION macro has also been removed. In a nutshell, there is no safe way to unload an LSM. The modular interface is thus unecessary and broken infrastructure. It is used only by out-of-tree modules, which are often binary-only, illegal, abusive of the API and dangerous, e.g. silently re-vectoring SELinux.
