Revision e19f9d65186d87258f05eae8a1b4e168594369fe authored by Mateusz Guzik on 18 July 2012, 04:52:37 UTC, committed by Mateusz Guzik on 18 July 2012, 04:52:37 UTC
Unbreak handling of descriptors opened with O_EXEC by fexecve(2). While here return EBADF for descriptors opened for writing (previously it was ETXTBSY). Add fgetvp_exec function which performs appropriate checks. == Follow-up commit to r238220: Pass only FEXEC (instead of FREAD|FEXEC) in fgetvp_exec. _fget has to check for !FWRITE anyway and may as well know about FREAD. Make _fget code a bit more readable by converting permission checking from if() to switch(). Assert that correct permission flags are passed.
