2013-11-25arm64: dts: Reserve the memory used for secondary CPU release addressCatalin Marinas1-0/+2
With the spin-table SMP booting method, secondary CPUs poll a location passed in the DT. The foundation-v8.dts file doesn't have this memory reserved and there is a risk of Linux using it before secondary CPUs are started. Signed-off-by: Catalin Marinas <[email protected]>
2013-11-25arm64: let the core code deal with preempt_countMarc Zyngier1-22/+7
Commit f27dde8deef3 (sched: Add NEED_RESCHED to the preempt_count) introduced the use of bit 31 in preempt_count for obscure scheduling purposes. This causes interrupts taken from EL0 to hit the (open coded) BUG when this flag is flipped while handling the interrupt (we compare the values before and after, and kill the kernel if they are different). The fix is to stop messing with the preempt count entirely, as this is already being dealt with in the generic code (irq_enter/irq_exit). Tested on a dual A53 FPGA running cyclictest.

2013-11-25n_tty: Fix 4096-byte canonical readsPeter Hurley1-1/+4
Although the maximum allowable canonical line is specified to be 255 bytes (MAX_CANON), the practical limit has actually been the size of the line discipline read buffer (N_TTY_BUF_SIZE == 4096). Commit 32f13521ca68bc624ff6effc77f308a52b038bf0, n_tty: Line copy to user buffer in canonical mode, limited the line copy to 4095 bytes. With a completely full line discipline read buffer and a userspace buffer > 4095, _no_ data was copied, and the read() syscall returned 0, indicating EOF. Fix the interval arithmetic to compute the correct number of bytes to copy to userspace in the range [1..4096].

2013-11-25n_tty: Ensure reader restarts worker for next readerPeter Hurley1-2/+3
A departing reader must restart a flush_to_ldisc() worker _before_ the next reader enters the read loop; this is to avoid the new reader concluding no more i/o is available and prematurely exiting, when the old reader simply hasn't re-started the worker yet.

2013-11-25[CIFS] Do not use btrfs refcopy ioctl for SMB2 copy offloadSteve French1-2/+4
Change cifs.ko to using CIFS_IOCTL_COPYCHUNK instead of BTRFS_IOC_CLONE to avoid confusion about whether copy-on-write is required or optional for this operation. SMB2/SMB3 copyoffload had used the BTRFS_IOC_CLONE ioctl since they both speed up copy by offloading the copy rather than passing many read and write requests back and forth and both have identical syntax (passing file handles), but for SMB2/SMB3 CopyChunk the server is not required to use copy-on-write to make a copy of the file (although some do), and Christoph has commented that since CopyChunk does not require copy-on-write we should not reuse BTRFS_IOC_CLONE. This patch renames the ioctl to use a cifs specific IOCTL CIFS_IOCTL_COPYCHUNK. This ioctl is particularly important for SMB2/SMB3 since large file copy over the network otherwise can be very slow, and with this is often more than 100 times faster putting less load on server and client. Note that if a copy syscall is ever introduced, depending on its requirements/format it could end up using one of the other three methods that CIFS/SMB2/SMB3 can do for copy offload, but this method is particularly useful for file copy and broadly supported (not just by Samba server).

2013-11-25s390/mm: handle asce-type exceptions as normal page faultMartin Schwidefsky1-1/+1
Git commit 9e34f2686bb088b211b6cac8772e1f644c6180f8 "s390/mm,tlb: tlb flush on page table upgrade fixup" removed the exception handler for the asce-type exception. This is incorrect as the user-copy with MVCOS can cause asce-type exceptions in the kernel if a user pointer is too large. Those need to be handled with do_no_context to branch to the fixup in the user-copy code. The simplest fix for this problem is to call do_dat_exception for asce-type excpetions, as there is no vma for the address the code will handle the exception correctly.

2013-11-25s390,time: revert direct ktime path for s390 clockevent deviceMartin Schwidefsky1-15/+4
Git commit 4f37a68cdaf6dea833cfdded2a3e0c47c0f006da "s390: Use direct ktime path for s390 clockevent device" makes use of the CLOCK_EVT_FEAT_KTIME clockevent option to avoid the delta calculation with ktime_get() in clockevents_program_event and the get_tod_clock() in s390_next_event. This is based on the assumption that the difference between the internal ktime and the hardware clock is reflected in the wall_to_monotonic delta. But this is not true, the ntp corrections are applied via changes to the tk->mult multiplier and this is not reflected in wall_to_monotonic. In theory this could be solved by using the raw monotonic clock but it is simpler to switch back to the standard clock delta calculation. Signed-off-by: Martin Schwidefsky <[email protected]>

When translating a user space address, the address must be checked against the ASCE limit of the process. If the address is larger than the maximum address that is reachable with the ASCE, an ASCE type exception must be generated. The current code simply ignored the higher order bits.

GPIO mapping properties were defined using the GPIOF_* flags, which are declared in linux/gpio.h. This file is not included when using the GPIO descriptor interface. This patch declares the flags that can be used as GPIO mappings properties in linux/gpio/driver.h, and uses them in gpiolib, so that no deprecated declarations are used by the GPIO descriptor interface.

2013-11-25Documentation: gpiolib: document new interfaceAlexandre Courbot6-0/+661
gpiolib now exports a new descriptor-based interface which deprecates the older integer-based one. This patch documents this new interface and also takes the opportunity to brush-up the GPIO documentation a little bit. The new descriptor-based interface follows the same consumer/driver model as many other kernel subsystems (e.g. clock, regulator), so its documentation has similarly been splitted into different files. The content of the former documentation has been reused whenever it made sense; however, some of its content did not apply to the new interface anymore and have this been removed. Likewise, new sections like the mapping of GPIOs to devices have been written from scratch. The deprecated legacy-based documentation is still available, untouched, under Documentation/gpio/gpio-legacy.txt.

2013-11-25powerpc/signals: Improved mark VSX not saved with small contexts fixMichael Neuling2-9/+13
In a recent patch: commit c13f20ac48328b05cd3b8c19e31ed6c132b44b42 Author: Michael Neuling <[email protected]> powerpc/signals: Mark VSX not saved with small contexts We fixed an issue but an improved solution was later discussed after the patch was merged. Firstly, this patch doesn't handle the 64bit signals case, which could also hit this issue (but has never been reported). Secondly, the original patch isn't clear what MSR VSX should be set to. The new approach below always clears the MSR VSX bit (to indicate no VSX is in the context) and sets it only in the specific case where VSX is available (ie. when VSX has been used and the signal context passed has space to provide the state). This reverts the original patch and replaces it with the improved solution. It also adds a 64 bit version.

2013-11-25powerpc/kdump: Adding symbols in vmcoreinfo to facilitate dump filteringHari Bathini2-0/+13
When CONFIG_SPARSEMEM_VMEMMAP option is used in kernel, makedumpfile fails to filter vmcore dump as it fails to do vmemmap translations. So far dump filtering on ppc64 never had to deal with vmemmap addresses seperately as vmemmap regions where mapped in zone normal. But with the inclusion of CONFIG_SPARSEMEM_VMEMMAP config option in kernel, this vmemmap address translation support becomes necessary for dump filtering. For vmemmap adress translation, few kernel symbols are needed by dump filtering tool. This patch adds those symbols to vmcoreinfo, which a dump filtering tool can use for filtering the kernel dump. Tested this changes successfully with makedumpfile tool that supports vmemmap to physical address translation outside zone normal.

functions Commit bceaa90240b6019ed73b49965eac7d167610be69 ("inet: prevent leakage of uninitialized memory to user in recv syscalls") conditionally updated addr_len if the msg_name is written to. The recv_error and rxpmtu functions relied on the recvmsg functions to set up addr_len before. As this does not happen any more we have to pass addr_len to those functions as well and set it to the size of the corresponding sockaddr length. This broke traceroute and such.

2013-11-23gro: Clean up tcpX_gro_receive checksum verificationHerbert Xu2-33/+20
This patch simplifies the checksum verification in tcpX_gro_receive by reusing the CHECKSUM_COMPLETE code for CHECKSUM_NONE. All it does for CHECKSUM_NONE is compute the partial checksum and then treat it as if it came from the hardware (CHECKSUM_COMPLETE).
