s390: appldata: drop owner assignment from platform_drivers

2014-10-20T14:20:13+00:00

A platform_driver does not need to set an owner, it will be populated by the
driver core.

s390/appldata_os: fix cpu array size calculation

2014-03-07T14:25:55+00:00

The cpu array size calculation uses the NR_CPUS config option, which
was recently increased from 64 to 256. With a value of 256, the cpu
array will no longer fit into one APPLDATA record and loading the
appldata_os module fails with the following error:
could not insert 'appldata_os': Cannot allocate memory

Use num_possible_cpus() instead of NR_CPUS. For z/VM, this will still
result in a value of 64. This is not true for LPAR, but the appldata
feature is not available for LPAR.

s390/appldata: restore missing init_virt_timer()

2014-01-29T08:07:51+00:00

Commit 27f6b416 "s390/vtimer: rework virtual timer interface" removed
the call to init_virt_timer() by mistake, which is added again by this
patch.

s390: convert use of typedef ctl_table to struct ctl_table

2013-10-28T07:36:25+00:00

This typedef is unnecessary and should just be removed.

s390/appldata: make copy_from_user() invocations provably correct

2013-10-24T15:17:07+00:00

Just change the type of "len" to unsigned int so the compiler can prove
that we don't have a buffer overflow (and generates less code).
We get rid of these:

In function 'copy_from_user',
    inlined from 'appldata_interval_handler' at
    arch/s390/appldata/appldata_base.c:265:
      uaccess.h:303: warning: call to 'copy_from_user_overflow' declared

s390/appldata_net_sum: do not use static data

2013-06-26T19:10:31+00:00

Using static data for fields which are accessed by HW will fail if
the driver is build as a module (since this would be vmalloc'ed
memory). This Bug was revealed via
"s390: remove virt_to_phys implementation" - the old virt_to_phys
implementation would have translated the address but it was not
guaranteed that the memory was contiguous.

arch: s390: appldata: using strncpy() and strnlen() instead of sprintf()

2013-05-28T08:35:28+00:00

'buf[2]' is 2 bytes length, and sprintf() will append '\0' at the end
of string "?\n", so original implementation is memory overflow.

Need use strncpy() and strnlen() instead of sprintf().
