There's a bug in the Hitachi SuperH csum_partial_copy_generic() implementation. If the supplied length is 1 (and several alignment conditions are met), the function immediately branches to label 4. However, the assembly at label 4 expects the length to be stored in register r2. Since this has not occurred, subsequent behavior is undefined. This can cause bad payload checksums in TCP connections. I've fixed the problem by initializing register r2 prior to the branch instruction.

We had a pretty interesting oops happening, where copy_user_page() was down()'ing p3map_sem[] with a bogus offset (particularly, an offset that hadn't been initialized with sema_init(), due to the mismatch between cpu_data->dcache.n_aliases and what was assumed based off of the old CACHE_ALIAS value). Luckily, spinlock debugging caught this for us, and so we drop the old hardcoded CACHE_ALIAS for sh4 completely and rely on the run-time probed cpu_data->dcache.alias_mask. This in turn gets the p3map_sem[] index right, and everything works again. While we're at it, also convert to 4-level page tables.. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

Paul Mundt authored
flush_cache_range() wasn't page aligning the end of the range, we can't assume that it will always be page aligned, and we ended up getting unaligned faults in some rare call paths. Additionally, we add a small optimization to just purge the dcache entirely if the range is large enough that the page table walking will take longer. We use an arbitrary value of 64 pages for the large range size, as per sh64. Signed-off-by: Paul Mundt <lethal@linux-sh.org>

Convert cmm's usage of kernel_thread to kthread_run. Also create the cmmthread at module load time, so it is possible to check if creation of the thread fails. In addition the cmmthread now gets terminated when the module gets unloaded instead of leaving a stale kernel thread. Also check the return values of other registration functions at module load and handle their return values appropriately.

Include the host architecture's ptrace-abi.h instead of ptrace.h. There was some cpp mangling of names around the ptrace.h include to avoid symbol clashes between UML and the host architecture. Most of these can go away. The exception is struct pt_regs, which is convenient to have in userspace, but must be renamed in order that UML can define its own. ptrace-x86_64.h needed to have some now-obsolete cpp cruft and a declaration removed.

The use of SEGMENT_RPL_MASK in the i386 ptrace.h introduced by x86-allow-a-kernel-to-not-be-in-ring-0.patch broke the UML build, as UML includes the underlying architecture's ptrace.h, but has no easy access to the x86 segment definitions. Rather than kludging around this, as in the past, this patch splits the userspace-usable parts, which are the bits that UML needs, of ptrace.h into ptrace-abi.h, which is included back into ptrace.h. Thus, there is no net effect on i386. As a side-effect, this creates a ptrace header which is close to being usable in /usr/include. x86_64 is also treated in this way for consistency. There was some trailing whitespace there, which is cleaned up.

The KSTK_* macros used an inordinate amount of stack. In order to overcome an impedance mismatch between their interface, which just returns a single register value, and the interface of get_thread_regs, which took a full pt_regs, the implementation created an on-stack pt_regs, filled it in, and returned one field. do_task_stat calls KSTK_* twice, resulting in two local pt_regs, blowing out the stack. This patch changes the interface (and name) of get_thread_regs to just return a single register from a jmp_buf. The include of archsetjmp.h" in registers.h to get the definition of jmp_buf exposed a bogus include of <setjmp.h> in start_up.c. <setjmp.h> shouldn't be used anywhere any more since UML uses the klibc setjmp/longjmp.
