* Fix [set_]kernel_pointer for 32-bitHEADmasterJosh Stone2010-04-131-1/+1
| | | | | * tapset/conversions.stp (kernel_pointer): Use uintptr_t casts. * tapset/conversions-guru.stp (set_kernel_pointer): Ditto.
* Title for kernel_pointer needs to be all on one line.William Cohen2010-04-081-2/+1

* Added kernel_pointer()/set_kernel_pointer() tapset functions.David Smith2010-04-071-1/+19
| | | | | | | | | | | * tapset/conversions.stp (kernel_pointer): New function. * tapset/conversions-guru.stp (set_kernel_pointer): Ditto. * testsuite/buildok/conversions-embedded.stp: Added kernel_pointer() test. * testsuite/buildok/conversions.stp: Ditto. * testsuite/buildok/set_kernel.stp: Added set_kernel_pointer() test. * tapset/nfs.stp: Removed __d_loff_t() function. Uses new kernel_pointer() function instead. * testsuite/buildok/nfs-embedded.stp: Removed __d_loff_t() test.
* Use clamping to more easily normalize input valuesJosh Stone2010-02-161-8/+4
| | | | | | The kernel has min/max/clamp macros to make range comparisons easier. Clamp is a newer invention, but we can define it for older kernels in terms of min and max.
* Add documentation for conversions.stp tapset functions.Mark Wielaard2009-11-121-7/+179
| | | | | * doc/SystemTap_Tapset_Reference/tapsets.tmpl: Add conversions.stp chapter. * tapset/conversions.stp: Add documentation for all functions.
* PR10650: markup some unprivileged-safe tapset functionsFrank Ch. Eigler2009-09-161-17/+33
| | | | | | | | | | | | | | | | | Add /* unprivileged */ to a variety of tapset embedded-c functions, together with uid-assertion-checking code as needed. This is only an initial set, and may need to grow or shrink after further testing. Prototyped-By: Dave Brolley <brolley@redhat.com> * runtime/runtime.h (is_myproc, assert_is_myproc): New macros. * runtime/addr-map.c (lookup_bad_addr): Reject if !is_myproc in unprivileged mode. * runtime/print.c (_stp_print_kernel_info): Add unprivileged mode info. * tapset/DEVGUIDE: Document /* pure */ and /* unprivileged */. * tapset/*.stp: Add /* unprivileged */ here and there, in questionable cases along with an assert_is_myproc().
* Correct a few comments to match the codeJosh Stone2009-08-261-4/+4
| | | | | | | * tapset/conversions.stp (kernel_long, kernel_int, kernel_short, kernel_char): All are actually using kread(), not deref(). * tapset/i386/registers.stp (_stp_arg): Ditto. * tapset/x86_64/registers.stp (_stp_arg): Ditto.
* Make sure user_string_n() results are always zero terminated strings.Mark Wielaard2009-04-281-1/+4
| | | | | | * tapset/conversions.stp (user_string_n2): Explicitly null terminate return string. (user_string_n_warn): Likewise.
