Best practice is to not mix lseek/read with fseek/fread on the same underlying file descriptor, as not all stdio implementations will cope. Since the plugin uses lseek/read while bfd uses fseek/fread this patch reopens the file for exclusive use by the plugin rather than trying to restore the file descriptor. That allows the plugin to read the file after plugin_call_claim_file too. bfd/ PR 23254 * plugin.c (bfd_plugin_open_input): Allow for possibility of nested archives. Open file again for plugin. (try_claim): Don't save and restore file position. Close file if not claimed. * sysdep.h (O_BINARY): Define. ld/ PR 23254 * plugin.c (plugin_call_claim_file): Revert 2016-07-19 patch. (plugin_object_p): Don't dup file descriptor.
