https://sourceware.org/bugzilla/show_bug.cgi?id=29267 Bug ID: 29267 Summary: readelf..info misreports DW_FORM_loclistx, DW_FORM_rnglistx Product: binutils Version: 2.39 (HEAD) Status: UNCONFIRMED Severity: normal Priority: P2 Component: binutils Assignee: unassigned at sourceware dot org Reporter: sevaa at sprynet dot com Target Milestone: --- When readelf --debug-dump=info prints attributes of type DW_FORM_loclistx, DW_FORM_rnglistx, it prints what should be the offset of the loclist/rangelist in the respective section. The raw value of this attribute is supposed to be an index into the offsets table in the compilation unit header inside the debug_loclists or debug_rnglists sections, respectively, while the address of the offset table itself should be taken from the DW_AT_loclists_base or DW_AT_rnglists_base, respecively, in the CU's top DIE. But it looks like readelf looks up the offset in the debug_addr section, instead of debug_loclists/debug_rnglists section. This even causes warnings of type "Offset into section .debug_addr too big:", because the offset was never meant to be in .debug_addr. I've got a repro for that from clang++-11, but it's big. I'll try to find a smaller one. -- You are receiving this mail because: You are on the CC list for the bug.

https://sourceware.org/bugzilla/show_bug.cgi?id=29268 Bug ID: 29268 Summary: readelf misinterprets register rule inheritance from CIE to FDE Product: binutils Version: 2.39 (HEAD) Status: UNCONFIRMED Severity: normal Priority: P2 Component: binutils Assignee: unassigned at sourceware dot org Reporter: sevaa at sprynet dot com Target Milestone: --- Created attachment 14154 --> https://sourceware.org/bugzilla/attachment.cgi?id=14154=edit Test binary Consider the debug info attached binary. The binary's first FDE in .eh_frame has initial_location 0x1060, and the following instructions: DW_CFA_advance_loc 4# Move PC by 4 DW_CFA_undefined 16 # Change the rule for R16 to undefined The linked CIE marks R16 as the return address, and has the following instructions: DW_CFA_def_cfa 7, 8# CFA is at R7+8 DW_CFA_offset 16, 1# Set the rule for R16 to [CFA+1*data_aligment_factor]) The GNU readelf, if executed with --debug-dump=frames-interp, dumps the FDE as follows: 0018 0014 001c FDE cie= pc=1060..1086 LOC CFA ra 1060 rsp+8u 1064 rsp+8u Meanwhile, an alternative parser thinks that at the range [0x1060-0x1064), the rule for RA/R16 should be as inherited from the CIE, and it goes c-8. I've debugged readelf (the latest master, as of 06/01/22), to that point. There are two passes over the FDE instructions: one starting on dwarf.c:9296, the other starting at dwarf.c:9442. On the first pass, when DW_CFA_undefined is encountered, there is the following case statement: READ_ULEB (reg, start, block_end); if (frame_need_space (fc, reg) >= 0) fc->col_type[reg] = DW_CFA_undefined; break; If I understand correctly, the intended purpose of the first pass is to allocate enough memory in the fc->col_type and fc->col_offset arrays, and the logic of this operator's handling was meant to be: if this register was not mentioned before, allocate space for it, and reset its rule to undefined. HOWEVER, if the register WAS mentioned before (e. g. in the CIE), frame_need_space() returns 0, and the if() body executes anyway, and resets the rule for the register to undefined, erasing the initial state as specified by the CIE. I think the if statement should go, instead, "if (frame_need_space (fc, reg) > 0)". Same for other register-rule-type operators on the first pass. -- You are receiving this mail because: You are on the CC list for the bug.

https://sourceware.org/bugzilla/show_bug.cgi?id=29263 Nick Clifton changed: What|Removed |Added CC||nickc at redhat dot com --- Comment #2 from Nick Clifton --- (In reply to John David Anglin from comment #0) Hi David, > /usr/lib/gcc/hppa-linux-gnu/11/../../../hppa-linux-gnu/crtn.o: missing > .note.GNU-stack section implies executable stack > The first warning seems bogus as crtn.o is not an executable file. But it is an object file which is being linked with others to create an executable file. The logic of the .note.GNU-stack section is that its permissions (read/write/execute) define the permissions needed of the stack segment in the final executable. Permissions from different .note-GNU-stack sections in different input object files are ORed together. In addition, if the section is missing from any of the input object files then the target specific default permissions are assumed. For the HPPA architecture the default permissions are read, write and execute. Hence if the .note.GNU-stack section is missing from *any* input object file the resulting HPPA executable will end up with an executable stack segment. This is of course a potential security issue. > /usr/bin/ld: NOTE: This behaviour is deprecated and will be removed in a > future version of the linker The point of this message is that we are considering changing the behaviour of the linker so that all targets default to just read/write for their stacks, and that executable stacks have to be explicitly requested via the .note.GNU-stack mechanism. (This would match the behaviour of the lld linker). > On hppa-linux with kernel v5.18 and later, we don't need an executable > stack for signal support but we still need it for gcc nested functions. This is already handled by gcc. If an executable stack is needed in order to support nested functions (or more probably, taking the address of a nested function), then gcc will generate a .note.GNU-stack section with the read, write and execute permissions set. The linker will then obligingly create an executable stack segment. You will still get a warning message however, since the issue of executable stacks is still present, albeit for a different reason. The linker's warnings can be suppressed however, either via a run-time command line option: --no-warn-execstack or a build-time configure option: --enable-warn-execstack=no. Is this sufficient ? We could change the configuration option so that it defaults to disabling the warnings if the target is the HPPA, but I would prefer not to do that, as it means that a potential security vulnerability will be ignored by default.
