* PR11234: Ensure __get_argv doesn't overflowJosh Stone2010-01-283-11/+82
| | | | | | | That function was calling strlcpy as if the return value was the number of bytes copied, but strlcpy actually returns the length of the input string. We now use min() to handle the case when it's bigger than the buffer length, and drop out of the loop when that happens.

| * PR11195: Prevent all nested argument substitutionJosh Stone2010-01-193-31/+43
| | | | | | | | | | | | | | | | | | | | | | Our existing protection only made sure that the first token in a substitution wasn't a nested substitution. That's not sufficient when there could be multiple tokens involved. This patch makes sure that no nested tokens are ever allowed to be argument substitutions. This also adds a cursor_suspended_line/column and resets the main cursor_line/column to the beginning of the substitution, so errors will point a little closer to the right place.

| * Swap DW_OP_shr and DW_OP_shra.Roland McGrath2010-01-191-2/+2
| | | | | | | | * loc2c.c (translate): DW_OP_shr is unsigned, DW_OP_shra is signed.
| * Use signed division for DW_OP_div.Roland McGrath2010-01-191-1/+10
| | | | | | | | * loc2c.c (translate): Use signed division for DW_OP_div.
| * Fix the listing mode of process.library.markJosh Stone2010-01-181-1/+1
| | | | | | | | | | | | | | | | | | Our hack for producing nicer listing modes was to write the mark name in component index 1. That's fine for process.mark, but writes the wrong position for process.library.mark. It now munges the last probe component of any number of indexes. (A better fix is due in PR10831, preserving the derivation chain.)

| | | | | | | | | | | | | | | | | | | | | | | | | | Our literal_addr_to_sym_addr() function was just wrong. To compensate for raw addresses read from elf (either given by the user or through a mark transformation) we need to know what the elf_bias is (as returned by dwfl_module_getelf) before feeding them to any libdwfl functions. * tapsets.cxx (query_module_dwarf): Always add elf_bias to raw function or statement addresses before calling query_addr(). (query_addr): Don't call literal_addr_to_sym_addr(). * dwflpp.h (literal_addr_to_sym_addr): Removed. * dwflpp.cxx (literal_addr_to_sym_addr): Likewise.
