* Fixup some memory tapset vm kernel function probe fallbacks.Mark Wielaard2009-12-293-20/+53
| | | | | | | | | | | | | | | | | | | | | | | | | Older kernels don't have all GFP constants defined, and the fallback kernel function probe fallbacks don't have the same dwarf variable names as the kernel trace point probes. So replace them with variables that are available. bytes_alloc was sometimes a long and sometimes a string, this caused scripts to fail depending on which alternative was chosen for a particular kernel. So make it a long always. This isn't a full solution since kmalloc is always inlined which makes the kernel.function("kmalloc").return probe fail. * tapset/memory.stp: Define __GFP_THISNODE, __GFP_RECLAIMABLE, GFP_TEMPORARY, GFP_HIGHUSER_MOVABLE and GFP_THISNODE when not yet defined. (__vm.kmalloc.kp): Use $flags, not $gfp_flags. Set bytes_alloc equal to bytes_req. (__vm.kmem_cache_alloc.kp): Likewise. And use $cachep->buffer_size for bytes_req. (__vm.kmalloc_node.kp): Likewise. (__vm.kmem_cache_alloc_node.kp): Likewise. (__vm.kfree.kp): Use $ibjp for ptr, not $return. (__vm.kmem_cache_free.kp): Likewise. * testsuite/buildok/vm.tracepoints.stp: Move vm.kmalloc test to... * testsuite/buildok/vm.tracepoints.kmalloc.stp: ... here.
* Remove all caching from _stp_module_relocate.Mark Wielaard2009-12-291-38/+13
| | | | | | | | | | | This function now also does user space address relocation. The connection with module loading/unloading was removed in commit 1b94bf which made all symbol tables emitted at compile time. _stp_module_relocate is called from the dwarf unwinder, and when doing some of the symbol lookup through dwflpp::emit_adress now. * runtime/sym.c (_stp_module_relocate): Remove last, last_sec and last_tsk caching and invalidation code.
* Guard SDEV_BLOCK and SDEV_CREATED_BLOCK in tapset/scsi.stp with #ifdef.Mark Wielaard2009-12-291-0/+4
| | | | | Older kernels didn't define these constants, which are only used in the tapset/scsi.stp describe_device_state() function.

| * PR11112: Check the full %m/M buffer, and limit the lengthJosh Stone2009-12-211-13/+26
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | We already had code in place to try a deref on the requested memory buffer, but it was missing the static-precision case. Thus, it was possible to craft an address that would pass the check on the first byte but would pagefault at the end of the buffer. While we're at it, we should also be limiting the number of bytes in such a read, so even legitimately-huge buffers won't chew up kernel time. I've arbitrarily chosen 1024 as the limit, but we can revisit that later. (see also PR10490) TODO: we need a reliable testcase where a starting address is valid but the end address is bogus. In PR11112, the reproducer was using a huge precision to run off the heap, but we need something that will consistently work even with <1024 length.
