2014-05-28init.h: Update initcall_sync variants to fix build errorsTony Lindgren1-1/+13
We are getting randconfig build errors on device drivers with tristate Kconfig option if they are using custom initcall levels. Rather than add ifdeffery into the drivers, let's add the missing initcall_sync variants. As the comment in init.h has kept people from updating the list of initcalls that can be just module_init when the driver is loaded as a loadable module, let's also update the comment a bit to describe valid use cases custom initcall levels. While most drivers should nowadays use just regular module_init because of the deferred probe, we do have quite a few custom initcall levels left that we cannot remove until tested properly. There are also still few valid cases where a custom initcall level might make sense that I'm aware of. For example a bus snooping driver can provide information about invalid bus access and is handy loader early when built in. But there's no hard dependency to have it necessarily built in and a loadable module is a valid option. Another example is a driver implementing a Linux framework like pinctrl framework. That driver may be needed early on some platforms because of legacy reasons, while it can be just a regular module_init on most platforms.

2014-05-14MIPS: Add new AUDIT_ARCH token for the N32 ABI on MIPS64Markos Chandras1-0/+12
A MIPS64 kernel may support ELF files for all 3 MIPS ABIs (O32, N32, N64). Furthermore, the AUDIT_ARCH_MIPS{,EL}64 token does not provide enough information about the ABI for the 64-bit process. As a result of which, userland needs to use complex seccomp filters to decide whether a syscall belongs to the o32 or n32 or n64 ABI. Therefore, a new arch token for MIPS64/n32 is added so it can be used by seccomp to explicitely set syscall filters for this ABI.

2014-05-13cgroup: introduce task_css_is_root()Tejun Heo1-0/+15
Determining the css of a task usually requires RCU read lock as that's the only thing which keeps the returned css accessible till its reference is acquired; however, testing whether a task belongs to the root can be performed without dereferencing the returned css by comparing the returned pointer against the root one in init_css_set[] which never changes. Implement task_css_is_root() which can be invoked in any context. This will be used by the scheduled cgroup_freezer change. v2: cgroup no longer supports modular controllers. No need to export init_css_set. Pointed out by Li. Signed-off-by: Tejun Heo <tj@kernel.org> Acked-by: Li Zefan <lizefan@huawei.com>
2014-05-13kernfs, sysfs, cgroup: restrict extra perm check on open to sysfsTejun Heo1-1/+18
The kernfs open method - kernfs_fop_open() - inherited extra permission checks from sysfs. While the vfs layer allows ignoring the read/write permissions checks if the issuer has CAP_DAC_OVERRIDE, sysfs explicitly denied open regardless of the cap if the file doesn't have any of the UGO perms of the requested access or doesn't implement the requested operation. It can be debated whether this was a good idea or not but the behavior is too subtle and dangerous to change at this point. After cgroup got converted to kernfs, this extra perm check also got applied to cgroup breaking libcgroup which opens write-only files with O_RDWR as root. This patch gates the extra open permission check with a new flag KERNFS_ROOT_EXTRA_OPEN_PERM_CHECK and enables it for sysfs. For sysfs, nothing changes. For cgroup, root now can perform any operation regardless of the permissions as it was before kernfs conversion. Note that kernfs still fails unimplemented operations with -EINVAL. While at it, add comments explaining KERNFS_ROOT flags.

2014-05-07genirq: Provide irq_force_affinity fallback for non-SMPArnd Bergmann1-0/+5
Patch 01f8fa4f01d "genirq: Allow forcing cpu affinity of interrupts" added an irq_force_affinity() function, and 30ccf03b4a6 "clocksource: Exynos_mct: Use irq_force_affinity() in cpu bringup" subsequently uses it. However, the driver can be used with CONFIG_SMP disabled, but the function declaration is only available for CONFIG_SMP, leading to this build error: drivers/clocksource/exynos_mct.c:431:3: error: implicit declaration of function 'irq_force_affinity' [-Werror=implicit-function-declaration] irq_force_affinity(mct_irqs[MCT_L0_IRQ + cpu], cpumask_of(cpu)); This patch introduces a dummy helper function for the non-SMP case that always returns success, to get rid of the build error.

2014-05-07hugetlb: ensure hugepage access is denied if hugepages are not supportedNishanth Aravamudan1-0/+10
Currently, I am seeing the following when I `mount -t hugetlbfs /none /dev/hugetlbfs`, and then simply do a `ls /dev/hugetlbfs`. I think it's related to the fact that hugetlbfs is properly not correctly setting itself up in this state?: Unable to handle kernel paging request for data at address 0x00000031 Faulting instruction address: 0xc000000000245710 Oops: Kernel access of bad area, sig: 11 [#1] SMP NR_CPUS=2048 NUMA pSeries .... In KVM guests on Power, in a guest not backed by hugepages, we see the following: AnonHugePages: 0 kB HugePages_Total: 0 HugePages_Free: 0 HugePages_Rsvd: 0 HugePages_Surp: 0 Hugepagesize: 64 kB HPAGE_SHIFT == 0 in this configuration, which indicates that hugepages are not supported at boot-time, but this is only checked in hugetlb_init(). Extract the check to a helper function, and use it in a few relevant places. This does make hugetlbfs not supported (not registered at all) in this environment. I believe this is fine, as there are no valid hugepages and that won't change at runtime.

2014-05-04arm64: fixmap: fix missing sub-page offset for earlyprintkMarc Zyngier1-0/+3
Commit d57c33c5daa4 (add generic fixmap.h) added (among other similar things) set_fixmap_io to deal with early ioremap of devices. More recently, commit bf4b558eba92 (arm64: add early_ioremap support) converted the arm64 earlyprintk to use set_fixmap_io. A side effect of this conversion is that my virtual machines have stopped booting when I pass "earlyprintk=uart8250-8bit,0x3f8" to the guest kernel. Turns out that the new earlyprintk code doesn't care at all about sub-page offsets, and just assumes that the earlyprintk device will be page-aligned. Obviously, that doesn't play well with the above example. Further investigation shows that set_fixmap_io uses __set_fixmap instead of __set_fixmap_offset. A fix is to introduce a set_fixmap_offset_io that uses the latter, and to remove the superflous call to fix_to_virt (which only returns the value that set_fixmap_io has already given us). With this applied, my VMs are back in business. Tested on a Cortex-A57 platform with kvmtool as platform emulation.

2014-05-01dentry_kill(): don't try to remove from shrink listAl Viro1-0/+2
If the victim in on the shrink list, don't remove it from there. If shrink_dentry_list() manages to remove it from the list before we are done - fine, we'll just free it as usual. If not - mark it with new flag (DCACHE_MAY_FREE) and leave it there. Eventually, shrink_dentry_list() will get to it, remove the sucker from shrink list and call dentry_kill(dentry, 0). Which is where we'll deal with freeing. Since now dentry_kill(dentry, 0) may happen after or during dentry_kill(dentry, 1), we need to recognize that (by seeing DCACHE_DENTRY_KILLED already set), unlock everything and either free the sucker (in case DCACHE_MAY_FREE has been set) or leave it for ongoing dentry_kill(dentry, 1) to deal with.

He uncovered a race where the module when loaded will convert the calls to mcount into nops, and expects the module's text to be RW. But when function tracing is enabled, it will convert all kernel text (core and module) from RO to RW to convert the nops to calls to ftrace to record the function. After the convertion, it will convert all the text back from RW to RO. The issue is, it will also convert the module's text that is loading. If it converts it to RO before ftrace does its conversion, it will cause ftrace to fail and require a reboot to fix it again. This patch moves the ftrace module update that converts calls to mcount into nops to be done when the module state is still MODULE_STATE_UNFORMED.
