2012-11-26xen/acpi: Fix compile error by missing decleration for xen_domain.Konrad Rzeszutek Wilk
Commit 92e3229dcdc80ff0b6304f14c578d76e7e10e226 ("xen/acpi: ACPI PAD driver") adds a new function but forgets to use the right header. Without it, we get: In file included from drivers/xen/features.c:15:0: include/xen/interface/version.h: In function ‘xen_running_on_version_or_later’: include/xen/interface/version.h:72:2: error: implicit declaration of function ‘xen_domain’ [-Werror=implicit-function-declaration] Signed-off-by: Konrad Rzeszutek Wilk <konrad.wilk@oracle.com>
2012-11-26xen/acpi: revert pad config check in xen_check_mwaitLiu, Jinsong
With Xen acpi pad logic added into kernel, we can now revert xen mwait related patch df88b2d96e36d9a9e325bfcd12eb45671cbbc937 ("xen/enlighten: Disable MWAIT_LEAF so that acpi-pad won't be loaded. "). The reason is, when running under newer Xen platform, Xen pad driver would be early loaded, so native pad driver would fail to be loaded, and hence no mwait/monitor #UD risk again. Another point is, only Xen4.2 or later support Xen acpi pad, so we won't expose mwait cpuid capability when running under older Xen platform.

2012-11-26xen/acpi: ACPI PAD driverLiu, Jinsong
PAD is acpi Processor Aggregator Device which provides a control point that enables the platform to perform specific processor configuration and control that applies to all processors in the platform. This patch is to implement Xen acpi pad logic. When running under Xen virt platform, native pad driver would not work. Instead Xen pad driver, a self-contained and thin logic level, would take over acpi pad logic. When acpi pad notify OSPM, xen pad logic intercept and parse _PUR object to get the expected idle cpu number, and then hypercall to hypervisor. Xen hypervisor would then do the rest work, say, core parking, to idle specific number of cpus on its own policy.

2012-11-02xen-pciback: reject out of range inputsJan Beulich
This add checks for out of range numbers (including in cases where the folding of slot and function into a single value could yield false matches). It also removes the bogus field width restrictions in str_to_quirk() - nowhere else in the driver this is being done, and hence this function could reject input the equivalent of which would be happily accepted in other places (in particular, "0x" prefixes causing the effective width of the actual number to be either zero or less than what would be required to cover the full range of valid values). Note that for the moment this second part is cosmetic only, as the kernel's sscanf() currently ignores the field widths, but a patch to overcome this is on its way.

2012-11-02xen-pciback: simplify and tighten parsing of device IDsJan Beulich
Now that at least one of the conformance problems of the kernel's sscanf() was addressed (commit da99075c1d368315e1508b6143226c0d27b621e0), we can improve the parsing done in xen-pciback both in terms of code readability and correctness (in particular properly rejecting input strings not well formed).

2012-11-02xen PVonHVM: use E820_Reserved area for shared_infoOlaf Hering
This is a respin of 00e37bdb0113a98408de42db85be002f21dbffd3 ("xen PVonHVM: move shared_info to MMIO before kexec"). Currently kexec in a PVonHVM guest fails with a triple fault because the new kernel overwrites the shared info page. The exact failure depends on the size of the kernel image. This patch moves the pfn from RAM into an E820 reserved memory area. The pfn containing the shared_info is located somewhere in RAM. This will cause trouble if the current kernel is doing a kexec boot into a new kernel. The new kernel (and its startup code) can not know where the pfn is, so it can not reserve the page. The hypervisor will continue to update the pfn, and as a result memory corruption occours in the new kernel. The toolstack marks the memory area FC000000-FFFFFFFF as reserved in the E820 map. Within that range newer toolstacks (4.3+) will keep 1MB starting from FE700000 as reserved for guest use. Older Xen4 toolstacks will usually not allocate areas up to FE700000, so FE700000 is expected to work also with older toolstacks. In Xen3 there is no reserved area at a fixed location. If the guest is started on such old hosts the shared_info page will be placed in RAM. As a result kexec can not be used.

2012-10-28Lock splice_read and splice_write functionsMikulas Patocka
Functions generic_file_splice_read and generic_file_splice_write access the pagecache directly. For block devices these functions must be locked so that block size is not changed while they are in progress. This patch is an additional fix for commit b87570f5d349 ("Fix a crash when block device is read and block size is changed at the same time") that locked aio_read, aio_write and mmap against block size change.

2012-10-28percpu-rw-semaphores: use rcu_read_lock_schedMikulas Patocka
Use rcu_read_lock_sched / rcu_read_unlock_sched / synchronize_sched instead of rcu_read_lock / rcu_read_unlock / synchronize_rcu. This is an optimization. The RCU-protected region is very small, so there will be no latency problems if we disable preempt in this region. So we use rcu_read_lock_sched / rcu_read_unlock_sched that translates to preempt_disable / preempt_disable. It is smaller (and supposedly faster) than preemptible rcu_read_lock / rcu_read_unlock.

2012-10-26VFS: don't do protected {sym,hard}links by defaultLinus Torvalds
In commit 800179c9b8a1 ("This adds symlink and hardlink restrictions to the Linux VFS"), the new link protections were enabled by default, in the hope that no actual application would care, despite it being technically against legacy UNIX (and documented POSIX) behavior. However, it does turn out to break some applications. It's rare, and it's unfortunate, but it's unacceptable to break existing systems, so we'll have to default to legacy behavior. In particular, it has broken the way AFD distributes files, see http://www.dwd.de/AFD/ along with some legacy scripts. Distributions can end up setting this at initrd time or in system scripts: if you have security problems due to link attacks during your early boot sequence, you have bigger problems than some kernel sysctl setting. Do: echo 1 > /proc/sys/fs/protected_symlinks echo 1 > /proc/sys/fs/protected_hardlinks to re-enable the link protections. Alternatively, we may at some point introduce a kernel config option that sets these kinds of "more secure but not traditional" behavioural options automatically.

2012-10-26qmi_wwan/cdc_ether: move Novatel 551 and E362 to qmi_wwanDan Williams
These devices provide QMI and ethernet functionality via a standard CDC ethernet descriptor. But when driven by cdc_ether, the QMI functionality is unavailable because only cdc_ether can claim the USB interface. Thus blacklist the devices in cdc_ether and add their IDs to qmi_wwan, which enables both QMI and ethernet simultaneously.

2012-10-26net: usb: Fix memory leak on Tx data pathHemant Kumar
Driver anchors the tx urbs and defers the urb submission if a transmit request comes when the interface is suspended. Anchoring urb increments the urb reference count. These deferred urbs are later accessed by calling usb_get_from_anchor() for submission during interface resume. usb_get_from_anchor() unanchors the urb but urb reference count remains same. This causes the urb reference count to remain non-zero after usb_free_urb() gets called and urb never gets freed. Hence call usb_put_urb() after anchoring the urb to properly balance the reference count for these deferred urbs. Also, unanchor these deferred urbs during disconnect, to free them up.

2012-10-26bas_gigaset: fix pre_reset handlingTilman Schmidt
The delayed work function int_in_work() may call usb_reset_device() and thus, indirectly, the driver's pre_reset method. Trying to cancel the work synchronously in that situation would deadlock. Fix by avoiding cancel_work_sync() in the pre_reset method. If the reset was NOT initiated by int_in_work() this might cause int_in_work() to run after the post_reset method, with urb_int_in already resubmitted, so handle that case gracefully.

2012-10-26ktest: Fix ktest confusion with CONFIG_MODULES_USE_ELF_RELASteven Rostedt
In order to decide if ktest should bother installing modules on the target box, it checks if the config file has CONFIG_MODULES=y. But it also checks if the '=y' part exists. It only will install modules if the config exists and is set with '=y'. But as the regex that was used tests: /^CONFIG_MODULES(=y)?/ this will also match: CONFIG_MODULES_USE_ELF_RELA as the '=y' part was optional and it did not test the rest of the line. When this happens, ktest will stop checking the rest of the configs but it will also think that no modules are needed to be installed. What it should do is only jump out of the loop if it actually found a CONFIG_MODULES that is set to true. Otherwise, ktest wont install the necessary modules needed for proper booting of the test target. Signed-off-by: Steven Rostedt <rostedt@goodmis.org>
