* Fix multi-piece constant failure in vta-test.exp on 32bit systems.Mark Wielaard2010-01-071-38/+38
| | | | | | | | | | | | | | | | | | | | | | | Commit 73b5e9 "Make sure loc2c declare_noncontig_union for different locs don't overlap", wasn't complete. It only took into account having a piece becuase of a noncontiguous loc and a constant loc together. But pieces can be nested deeper (newer gcc outputs multiple constant locations for one piece on 32bit systems). This patch keeps track of the piece declaration depth. Another approach could have been to have each sub-piece in its own local scope, but keeping track of the depth and naming the temporary unions distinct fitted the current code better. It currently only supports a depth of 10. An error will be emitted if a location construct needs more than 10 pieces to be assembled. * loc2c.c (declare_noncontig_union): Take depth argument. Always use the same name for the union (u_pieces<depth>). (translate_base_fetch): Take depth argument. Use it to calculate union names. (translate_base_store): Likewise. (c_translate_fetch): Pass in depth zero. (c_translate_store): Likewise. (c_translate_pointer): Likewise. (c_translate_pointer_store): Likewise.

* 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.

* 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.

| * 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.
