Bushnell, p/BSG * Makefile (exec): Link against fshelp too now. * exec.c (do_exec): Call proc_setowner *after* possible proc_reassign; otherwise it modifies the stub process's state and not the real process's.

Fri May 10 16:47:11 1996 Miles Bader * hashexec.c (search_path): Don't make PATH or PFXED_NAME const. Fri May 10 09:20:26 1996 Michael I.

Tue Apr 30 11:36:25 1996 Michael I. Bushnell, p/BSG * exec.c (check_gzip) [ziprderr]: Treat all read errors as ENOEXEC. First off, because that's what they are; also because some callers of read_error don't set errno at all. Mon Apr 29 15:11:55 1996 Michael I. Bushnell, p/BSG * exec.c (check_section): If the format makes no sense, return ENOEXEC, not EINVAL. (check_bfd): Likewise. (check_elf): Likewise. (check_elf_phdr): Likewise. (do_exec): Likewise. * exec.c (do_exec): Use correct args to ports_create_port. Sat Apr 27 06:02:42 1996 Roland McGrath * crash.c: Use ports_create_port instead of ports_allocate_port, and notice the error. * exec.c: Likewise. Tue Apr 23 18:53:54 1996 Roland McGrath * hashexec.c (check_hashbang: user_port): Use default root port when secure. Mon Apr 15 12:48:35 1996 Michael I.

Sat Jan 13 12:28:03 1996 Miles Bader * hashexec.c (check_hashbang): Use hash_file_name_path_lookup() instead of doing the path search ourselves, and get rid of LOOKUP_CWDIR & associated logic. * exec.c (S_exec_exec): Use strdupa(). Also update use of hurd_file_name_lookup() [still probably not right though]. Thu Jan 11 15:36:18 1996 Miles Bader * hashexec.c (check_hashbang): When using executable name found on the path, don't return alloca()ed memory from search_path(); use malloc() instead.

(check_elf): Extract all information from file header before calling `map' for program headers. Sat Nov 25 22:10:41 1995 Miles Bader * crash.c (S_msg_sig_post_untraced): Also let the debugger have the process back if it's posting the crashing signal.

Record load address in `loadbase'. (check_elf): Initialize `anywhere' and `loadbase'. (postload): Merged into load. (load): Perform postload functionality here, after calling finish_mapping. (finish): Take new flag arg; deallocate file port only if set. (do_exec): Pass flag to finish appropriately. Don't call finish_mapping and postload after load. KLUDGE: Load the interpreter before the program instead of after. Mon Jun 5 06:42:33 1995 Roland McGrath * exec.c: Majorly revamped: Now supports the ELF format directly.

(exec): Depend on -lbfd and -liberty. (CPPFLAGS): Append -DBFD; omit -DA_OUT_H=... (bfdexec): Target removed. * exec.c (load_section): fseek to desired position before freading. (input_room): Always map a page-aligned region. Thu Feb 9 01:01:57 1995 Roland McGrath * exec.c (check_section): Don't check SEC_RELOC flag. Wed Feb 8 19:48:11 1995 Michael I Bushnell * exec.c (load_section) [BFD]: BFD does not set SEC_HAS_CONTENTS on a.out BSS's ever; don't make zeroing of bss conditional on that. It's not clear exactly what SEC_HAS_CONTENTS is for anyhow; perhaps the Right Thing is to set in on BSS. In any case, don't depend on this flag here. Sat Jan 28 17:08:02 1995 Roland McGrath * exec.c (prepare): Give the stream a seek function. Sun Jan 22 03:16:17 1995 Roland McGrath * exec.c: Update BFD code; it works now. * hostarch.c [BFD]: Fix prototype.

Dereference F in setting __error member. (close_exec_stream): Provide all three args to vm_deallocate and cast the second one properly. Wed Aug 31 04:32:26 1994 Roland McGrath * exec.c (do_exec): Do check before task_suspend. #if 0'd out: If check gets ENOEXEC, call check_hashbang. (struct execdata): Move member `stream' outside of [BFD]. (load_section): Use fread instead of hand mapping and copying unconditionally (was [BFD]); old code left #if'd out. (close_exec_stream): Renamed from close_stdio_bfd; moved out of [BFD]. (input_room): Define unconditionally, not [BFD]. (check): Set up E->stream unconditionally.
