[Bug ld/30374] ld: Add --remap-inputs-file= to remap input files
https://sourceware.org/bugzilla/show_bug.cgi?id=30374 --- Comment #5 from Fangrui Song --- (In reply to Nick Clifton from comment #4) > OK, I have decided to commit my patch now, so that it gets into the next > release. If there are problems we can always reopen this PR. Thank you! I have tested the feature. It looks great. > ld foo.o --remap-inputs=foo.o=bar.o > > will not rename foo.o to bar.o, [...] I hope that this will be fine. Users can get adapted to this limitation. > One other thing: I wondered if we ought to accept the "@file" syntax in the > --remap-inputs option, as a synonym for --remap-inputs-file. What do you > think ? I think no. --remap-inputs @1.map would require extra work and the syntax is probably not conventional. -- You are receiving this mail because: You are on the CC list for the bug.
[Bug binutils/30595] New: strings crashes when told to search for strings of size 0xFFFFFFFF

Command arguments used to reproduce the bug: $ ./binutils/strings -n0x <(echo aa) double free or corruption (out) Aborted (core dumped) Behavior I observe that I believe is incorrect: strings crashes. I believe it should output nothing as there are no strings longer than 4294967295 characters in the provided input file. The bug appears to be caused by the following code: char *buf = (char *) xmalloc (sizeof (char) * (string_min + 1)); which ends up passing a value of 0 to xmalloc, which makes it allocate a 1-byte buffer, which strings then proceeds to immediately overflow while trying to read string_min characters into it. -- You are receiving this mail because: You are on the CC list for the bug.

There seem to be a couple of "lib6464" paths there. Could someone double check
that?

Lu Date: Wed Mar 4 20:32:35 2020 -0800 bfd: Improve nm and objdump without section header When there is no section header in an executable or shared library, we reconstruct dynamic symbol table from the PT_DYNAMIC segment, which contains DT_HASH/DT_GNU_HASH/DT_MIPS_XHASH, DT_STRTAB, DT_SYMTAB, DT_STRSZ, and DT_SYMENT entries, to improve nm and objdump. For DT_HASH, the number of dynamic symbol table entries equals the number of chains. For DT_GNU_HASH/DT_MIPS_XHASH, only defined symbols with non-STB_LOCAL indings are in hash table. Since DT_GNU_HASH/DT_MIPS_XHASH place all symbols with STB_LOCAL binding before symbols with other bindings and all undefined symbols defined ones in dynamic symbol table, the highest symbol index in DT_GNU_HASH/DT_MIPS_XHASH is the highest dynamic symbol table index. We can also get symbol version from DT_VERSYM, DT_VERDEF and DT_VERNEED entries. dt_symtab, dt_versym, dt_verdef, dt_verneed, dt_symtab_count, dt_verdef_count, dt_verneed_count and dt_strtab are added to elf_obj_tdata to store dynamic symbol table information.
