Subject: [PATCH] PR23254, ld.bfd mishandles file pointers while scanning
|
||||
archive
|
||||
|
||||
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.
|
||||
|
||||

||||

|
||||
* 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.

* plugin.c (plugin_call_claim_file): Revert 2016-07-19 patch.
|
||||
(plugin_object_p): Don't dup file descriptor.
