2017-04-21libiberty: Limit demangler maximum d_print_comp recursion call depth.Mark Wielaard2-3/+19
The fix for PR demangler/70909 and 67264 (endless demangler recursion) catches when a demangle_component is printed in a cycle. But that doesn't protect the call stack blowing up from non-cyclic nested types printed recursively through d_print_comp. This can happen by a (very) long mangled string that simply creates a very deep pointer or qualifier chain. Limit the recursive d_print_comp call depth for a d_print_info to 1K nested types. libiberty/ChangeLog: * cp-demangle.c (MAX_RECURSION_COUNT): New constant. (struct d_print_info): Add recursion field. (d_print_init): Initialize recursion. (d_print_comp): Check and update d_print_info recursion depth. From-SVN: r247056
2017-04-21libiberty: Always return NULL if d_add_substitution fails.Mark Wielaard2-1/+7
d_add_substitution can fail for various reasons, like when the subs array is full. If d_add_substitution fails d_substitution should return NULL early and not try to continue. Every other call of d_add_substitution is handled in the same way. libiberty/ChangeLog: * cp-demangle.c (d_substitution): Return NULL if d_add_substitution fails. From-SVN: r247055
2017-04-21libiberty: Don't update and remove did_subs field from demangler structs.Mark Wielaard3-12/+10
The d_info field did_subs was used for estimating the string output size. It was no longer used when the malloc-less callback interface was introduced in 2007 (svn r121305). But the field was still updated. When backtracking was introduced in 2013 (svn r205292) did_subs was also added to the d_info_checkpoint struct. But except for updating the field it was still not used. Since it is never used just stop updating the field and remove it from the two structs. libiberty/ChangeLog: * cp-demangle.h (struct d_info): Remove did_subs field. * cp-demangle.c (struct d_info_checkpoint): Likewise. (d_template_param): Don't update did_subs. (d_substitution): Likewise. (d_checkpoint): Don't assign did_subs. (d_backtrack): Likewise. (cplus_demangle_init_info): Don't initialize did_subs.

2017-03-27cplus_demangle_fill_component: Handle DEMANGLE_COMPONENT_RVALUE_REFERENCEPedro Alves2-0/+6
This patch almost a decade ago: ... 2007-08-31 Douglas Gregor <doug.gregor@gmail.com> * cp-demangle.c (d_dump): Handle DEMANGLE_COMPONENT_RVALUE_REFERENCE. (d_make_comp): Ditto. ... ... missed doing the same change to cplus_demangle_fill_component that was done to d_make_comp. I.e., teach it to only validate that we're not passing in a "right" subtree. GDB has recently (finally) learned about rvalue references, and a change to make it use cplus_demangle_fill_component more ran into an assertion because of this. (GDB is the only user of cplus_demangle_fill_component in both the gcc and binutils-gdb trees.) libiberty/ChangeLog: 2017-03-27 Pedro Alves <palves@redhat.com> * cp-demint.c (cplus_demangle_fill_component): Handle DEMANGLE_COMPONENT_RVALUE_REFERENCE.

2017-03-13libiberty: Initialize d_printing in all cplus_demangle_fill_* functions.Mark Wielaard2-0/+12
While integrating the d_printing recursion guard change into gdb I noticed we forgot to initialize the demangle_component d_printing field in cplus_demangle_fill_{name,extended_operator,ctor,dtor}. As is done in cplus_demangle_fill_{component,builtin_type,operator}. It happened to work because in gcc all demangle_components were allocated through d_make_empty. But gdb has its own allocation mechanism (as might other users). libiberty/ChangeLog: * cp-demangle.c (cplus_demangle_fill_name): Initialize demangle_component d_printing.

2016-11-15libiberty: demangler crash with missing :? or fold expression component.Mark Wielaard3-0/+19
When constructing an :? or fold expression that requires a third expression only the first and second were explicitly checked to not be NULL. Since the third expression is also required in these constructs it needs to be explicitly checked and rejected when missing. Otherwise the demangler will crash once it tries to d_print the NULL component. Added two examples to demangle-expected of strings that would crash before this fix. Found by American Fuzzy Lop (afl) fuzzer. From-SVN: r242451

In various situations the cplus_demangle () function could read past the end of input causing crashes. Add checks in various places to not advance the demangle string location and fail early when end of string is reached. Add various examples of input strings to the testsuite that would crash test-demangle before the fixes. Found by using the American Fuzzy Lop (afl) fuzzer. libiberty/ChangeLog: * cplus-dem.c (demangle_signature): After 'H', template function, no success and don't advance position if end of string reached.

2016-11-01libiberty: Fix memory leak in ada_demangle when symbol cannot be demangled.Mark Wielaard2-1/+7
When a symbol cannot be demangled in ada_demangle a new demangled VEC will be allocated without deleting the demangled VEC already in use. Running testsuite/test-demangle under valgrind will show the leak for this entry in testsuite/demangle-expected: # Elaborated flag (not demangled) --format=gnat x_E <x_E> 11 bytes in 1 blocks are definitely lost in loss record 1 of 1 at 0x4C27BE3: malloc (vg_replace_malloc.c:299) by 0x413FE7: xmalloc (xmalloc.c:148) by 0x4025EC: ada_demangle (cplus-dem.c:930) by 0x402C59: cplus_demangle (cplus-dem.c:892) by 0x400FEC: main (test-demangle.c:317) libiberty/ChangeLog: * cplus-dem.c (ada_demangle): Initialize demangled to NULL and XDELETEVEC demangled when unknown.

2016-09-10Fix -Wshadow warning in libiberty/cp-demangle.cMark Wielaard2-5/+10
valgrind contains a copy of the libiberty demangler which gets compiled with -Wshadow. That shows the following warning: cp-demangle.c: In function ‘d_substitution’: cp-demangle.c:3772:35: warning: declaration of ‘c’ shadows a previous local struct demangle_component *c; ^ cp-demangle.c:3708:8: note: shadowed declaration is here char c; ^ Fix that by renaming the struct demangle_component variable to dc. libiberty/ChangeLog: * cp-demangle.c (d_substitution): Change struct demangle_component variable name from c to dc.
