1996-01-11(check_hashbang):Miles Bader
When using executable name found on the path, don't return alloca()ed memory from search_path(); use malloc() instead. Use envz_get() to search the environment.
1996-01-11(S_exec_exec): Use envz_get() to search the environment.Miles Bader
1996-01-04(safe_bzero): Rewritten using hurd_catch_signal.Roland McGrath
1996-01-04(check_hashbang): Rearrange arg frobbing code somewhat to useRoland McGrath
hurd_catch_signal instead of old preemption interface.
1995-12-29(do_exec):Miles Bader
Be careful not to look at BOOT after we release our reference on it. Correctly initialize BOOT->intarray in the case where NINTS < INIT_INT_MAX but we don't alloc a new array.
1995-12-15(map): Rearrange code to fix some bugs and not remap unless necessary.Roland McGrath
(input_room): Simplify. (check_elf): Extract all information from file header before calling `map' for program headers.
1995-11-21(safe_bzero): New function, broken out of load_section.Roland McGrath
(load_section): Call it.
1995-11-21(going_down): Variable removed.Roland McGrath
(deadboot): Don't test it. Instead, use ports calls to check if there are no other live ports. (trivfs_goaway): Don't set it.
1995-11-21(check_hashbang): Undo boneheaded last change.Roland McGrath
1995-11-21(load_section): Undo boneheaded last change.Roland McGrath
1995-11-21(check_hashbang): Actually declare FILE_NAME and FILE volatile, notMichael I. Bushnell
the contents.
1995-11-21(check_hashbang) [prepare_args]: Declare FILE_NAME, ERROR, and NAMEMichael I. Bushnell
volatile.
1995-11-21(load_section): Declare ADDR and VM_PROT volatile.Michael I. Bushnell
1995-11-16(user_port): Fixed port selection logic.Roland McGrath

1995-10-24(struct bootinfo): Use vm_size_t for phdr_size.Roland McGrath
1995-10-18(check_hashbang: prepare_args): Enable and clean up code to guess the nameRoland McGrath
of the script before resorting to /dev/fd.
1995-10-18(check_hashbang): Copy passed args from the right place.Roland McGrath
1995-10-18Initial revisionRoland McGrath
1995-10-18(struct execdata): Moved to priv.h.Roland McGrath
(std_*, finish): Make global. (do_exec): Only reset CWDIR when null, even if secure. Actually call check_hashbang and return success if it does. Use new hurd_file_name_lookup protocol with private callbacks to open interpreter file on behalf of client. Remove `bootout' label; use `stdout' or `out' as appropriate instead. At `out' label always deref BOOT, which cleans it up iff necessary. (S_exec_exec): #if 0 out $EXECSERVERS processing for time being.
1995-10-18(SRCS, OBJS): Add hashexec.[co].Roland McGrath
(DIST_FILES): Remove it from here.
1995-10-18Added some #includes.Roland McGrath
(struct execdata): Moved here from exec.c. (std_*): Declare these. (finish, check_hashbang): Declare them.
1995-10-11Initial revisionRoland McGrath
1995-10-11(OBJS): Add main.o; remove fsysServer.o, notifyServer.o.Roland McGrath
(LCLHDRS): Add priv.h and execmutations.h. (exec-MIGSFLAGS): New variable. (exec): Depend on livtrivfs, libthreads, libshouldbeinlibc.
1995-10-11Initial revisionRoland McGrath
1995-10-11Server mechanics removed; now uses libtrivfs/libports.Roland McGrath
Main program split out into main.c. (std_lock): New variable (rwlock). (do_exec): Acquire reader lock to access std_ints and std_ports. (S_exec_setexecdata): Acquire writer lock to change them.
1995-10-02(do_exec): Doc fix.Michael I. Bushnell
1995-09-27(do_exec): Don't set NEWTASK's bootstrap port until after we have finishedRoland McGrath
completely with OLDTASK. (do_mach_notify_no_senders): Remove bogus mod_refs call on receive_portset.
1995-09-20(struct bootinfo): New members `phdr_addr', `phdr_size', `user_entry'.Roland McGrath
(do_exec): Set them. Code rearranged to construct bootinfo before looking up interpreter file, keep proper track of port rights and VM copied into bootinfo (there were leaks).
1995-09-16Remove vpath directive.Roland McGrath
1995-09-08(OTHERLIBS, CPPFLAGS): Disable bfd by default.Roland McGrath
1995-08-28(S_fsys_forward): New stub function.Roland McGrath
1995-07-31(SRCS): Added unzip.c, util.c, and inflate.c.Michael I. Bushnell
1995-07-07(bfd_mach_host_arch_mach): Remove assignment from inside if test.Michael I. Bushnell
1995-07-06Removed dependencies that are now automatically generated.Michael I. Bushnell
1995-07-05(OTHERLIBS): Define var.Michael I. Bushnell
(all, exec): Delete targets.
1995-07-05(exec): fooMichael I. Bushnell
1995-06-27(load_section): Remove assignments from if tests.Michael I. Bushnell
(map): Likewise. (prepare): Likewise. (load): Likewise. (servercopy): Likewise. (do_exec): Likewise. (S_exec_setexecdata): Likewise. (S_exec_exec): Put extra parens around assignment inside while test.
1995-06-08Rewritten to unconditionally return both BFD and ELF machine types.Roland McGrath
1995-06-08(struct execdata.info.elf): Add members `anywhere' and `loadbase'.Roland McGrath
(load_section): Use them; if `anywhere' set, load the section anywhere. 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.
1995-06-05Majorly revamped: Now supports the ELF format directly.Roland McGrath
Secondarily uses the BFD library #ifdef BFD. Supports gunzipping only #ifdef GZIP.
1995-05-12Add fsys_set_options, replacing fsys_mod_readonly.Miles Bader
1995-04-21(check_gzip): Rewind the stream before calling `get_method'.Roland McGrath
Open a new BFD on the uncompressed data stream before return.
1995-04-10(struct execdata) [BFD]: New member `interp_section'.Roland McGrath
(check_section): Notice section named ".interp" and set that pointer. (load_section): Do nothing if the section is zero size. When reading into our copy of the overlap page, don't read past the end of the section. (do_exec): Consolidate new subfunction `check_maybe_gzip'. If there is an interpreter section, load the interpreter file too, and use its entry point instead of the user program's. Cleaned up and made more robust deallocation of BOOT info on error. (deadboot): New function, split out of do_mach_port_notify_no_senders.
1995-04-09(vpath lib%.a): Move this after include ../Makeconf, since it uses aRoland McGrath
variable set there.
