2017-04-15parisc: fix bugs in pa_memcpyMikulas Patocka1-13/+14
The patch 554bfeceb8a22d448cd986fc9efce25e833278a1 ("parisc: Fix access fault handling in pa_memcpy()") reimplements the pa_memcpy function. Unfortunatelly, it makes the kernel unbootable. The crash happens in the function ide_complete_cmd where memcpy is called with the same source and destination address. This patch fixes a few bugs in pa_memcpy: * When jumping to .Lcopy_loop_16 for the first time, don't skip the instruction "ldi 31,t0" (this bug made the kernel unbootable) * Use the COND macro when comparing length, so that the comparison is 64-bit (a theoretical issue, in case the length is greater than 0xffffffff) * Don't use the COND macro after the "extru" instruction (the PA-RISC specification says that the upper 32-bits of extru result are undefined, although they are set to zero in practice) * Fix exception addresses in .Lcopy16_fault and .Lcopy8_fault * Rename .Lcopy_loop_4 to .Lcopy_loop_8 (so that it is consistent with .Lcopy8_fault) Cc: <stable@vger.kernel.org> # v4.9+ Fixes: 554bfeceb8a2 ("parisc: Fix access fault handling in pa_memcpy()") Signed-off-by: Mikulas Patocka <mpatocka@redhat.com> Signed-off-by: Helge Deller <deller@gmx.de>

2017-03-29parisc: Clean up fixup routines for get_user()/put_user()Helge Deller2-99/+1
Al Viro noticed that userspace accesses via get_user()/put_user() can be simplified a lot with regard to usage of the exception handling. This patch implements a fixup routine for get_user() and put_user() in such that the exception handler will automatically load -EFAULT into the register %r8 (the error value) in case on a fault on userspace. Additionally the fixup routine will zero the target register on fault in case of a get_user() call. The target register is extracted out of the faulting assembly instruction. This patch brings a few benefits over the old implementation: 1. Exception handling gets much cleaner, easier and smaller in size. 2. Helper functions like fixup_get_user_skip_1 (all of fixup.S) can be dropped. 3. No need to hardcode %r9 as target register for get_user() any longer. This helps the compiler register allocator and thus creates less assembler statements. 4. No dependency on the exception_data contents any longer. 5. Nested faults will be handled cleanly.

2017-03-29parisc: Fix access fault handling in pa_memcpy()Helge Deller2-458/+321
pa_memcpy() is the major memcpy implementation in the parisc kernel which is used to do any kind of userspace/kernel memory copies. Al Viro noticed various bugs in the implementation of pa_mempcy(), most notably that in case of faults it may report back to have copied more bytes than it actually did. Fixing those bugs is quite hard in the C-implementation, because the compiler is messing around with the registers and we are not guaranteed that specific variables are always in the same processor registers. This makes proper fault handling complicated. This patch implements pa_memcpy() in assembler. That way we have correct fault handling and adding a 64-bit copy routine was quite easy. Runtime tested with 32- and 64bit kernels.

2016-05-22parisc: Add native high-resolution sched_clock() implementationHelge Deller1-4/+2
Add a native implementation for the sched_clock() function which utilizes the processor-internal cycle counter (Control Register 16) as high-resolution time source. With this patch we now get much more fine-grained resolutions in various in-kernel time measurements (e.g. when viewing the function tracing logs), and probably a more accurate scheduling on SMP systems. There are a few specific implementation details in this patch: 1. On a 32bit kernel we emulate the higher 32bits of the required 64-bit resolution of sched_clock() by increasing a per-cpu counter at every wrap-around of the 32bit cycle counter. 2. In a SMP system, the cycle counters of the various CPUs are not syncronized (similiar to the TSC in a x86_64 system). To cope with this we define HAVE_UNSTABLE_SCHED_CLOCK and let the upper layers do the adjustment work. 3. Since we need HAVE_UNSTABLE_SCHED_CLOCK, we need to provide a cmpxchg64() function even on a 32-bit kernel. 4. A 64-bit SMP kernel which is started on a UP system will mark the sched_clock() implementation as "stable", which means that we don't expect any jumps in the returned counter. This is true because we then run only on one CPU. Signed-off-by: Helge Deller <deller@gmx.de>
2016-04-08parisc: Unbreak handling exceptions from kernel modulesHelge Deller1-0/+6
Handling exceptions from modules never worked on parisc. It was just masked by the fact that exceptions from modules don't happen during normal use. When a module triggers an exception in get_user() we need to load the main kernel dp value before accessing the exception_data structure, and afterwards restore the original dp value of the module on exit.

Since this seems to be a generic problem with gcc-4.7.x (and below), it's better to simplify the fault handlers in pa_memcpy to avoid this problem. Here is a simple reproducer for the problem: int main(int argc, char **argv) { int fd, nbytes; struct iovec wr_iovec[] = { { "TEST STRING ",32}, { (char*)0x40005000,32} }; // random memory. fd = open(DATA_FILE, O_RDWR | O_CREAT, 0666); nbytes = writev(fd, wr_iovec, 2); printf("return value = %d, errno %d (%s)\n", nbytes, errno, strerror(errno)); return 0; } In addition, John David Anglin wrote: There is no gcc PR as pa_memcpy is not legitimate C code. There is an implicit assumption that certain variables will contain correct values when an exception occurs and the code randomly jumps to one of the exception blocks. There is no guarantee of this. If a PR was filed, it would likely be marked as invalid.
