1996-07-08(S_exec_exec): Don't use unsafe MOVE_SEND in call to interruptibleMichael I. Bushnell
exec_exec stub.
1996-06-20(do_exec): In proc_setowner code, deal with error from auth_getidsMichael I. Bushnell
more loosely.
1996-06-20fixupMichael I. Bushnell
1996-06-20(do_exec): Call proc_setowner *after* possible proc_reassign;Michael I. Bushnell
otherwise it modifies the stub process's state and not the real process's.
1996-06-19(do_exec, S_exec_exec): Pass 0 for new LOOKUP arg to hurd_file_name_lookup.Miles Bader
1996-06-13(do_exec): Add code missing from last change.Michael I. Bushnell
1996-06-13(do_exec): If secure, set the owner with proc_setowner.Michael I. Bushnell
1996-05-10(do_exec): Use new auth_user_authenticate interface.Michael I. Bushnell
1996-05-03(map): Use F->__offset and F->__target properly.Roland McGrath
1996-05-02(map): Fix fencepost error in check of current mapping window.Roland McGrath
Request round_page (LEN) bytes in io_read to avoid many small reads.
1996-05-02(do_exec): Terminate OLDTASK if we get an error after killing its threadsRoland McGrath
and deallocating its address space.
1996-04-30(check_gzip) [ziprderr]: Treat all read errors as ENOEXEC. First off,Michael I. Bushnell
because that's what they are; also because some callers of read_error don't set errno at all.
1996-04-27Use ports_create_port instead of ports_allocate_port, and notice the error.Roland McGrath
1996-04-08(prepare):Miles Bader
If io_map returns EOPNOTSUPP, suppress the error, and still setup E's stream. (prepare_and_check): If prepare returns an error, do no more.
1996-01-30(S_exec_exec):Miles Bader
Use strdupa(). Update use of hurd_file_name_lookup() [still probably not right though].
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
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(load_section): Undo boneheaded last change.Roland McGrath
1995-11-21(load_section): Declare ADDR and VM_PROT volatile.Michael I. Bushnell
1995-11-13(S_exec_startup): Compatibility RPC removed.Roland McGrath
1995-11-13(load_section): Catch faults while zeroing partial bss page.Roland McGrath
1995-10-25(S_exec_startup_get_info): New function, modified from S_exec_startup.Roland McGrath
(S_exec_startup): Just call it.
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.
1995-10-11Server 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).
1995-08-28(S_fsys_forward): New stub function.Roland McGrath
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.
1995-06-08(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(load_section): fseek to desired position before freading.Roland McGrath
(input_room): Always map a page-aligned region.
1995-02-09(check_section): Don't check SEC_RELOC flag.Roland McGrath
1995-02-09(load_section): Don't check SEC_HAS_CONTENTS for clearing overlap bssMichael I. Bushnell
pages.
1995-01-28(prepare): Fix braino in last change.Roland McGrath
1995-01-28(prepare): Give the stream a seek function.Roland McGrath
1995-01-22Update BFD code; it works now.Roland McGrath
1995-01-15[BFD] (bfd_mach_host_arch_mach): In decl, MACHINE arg is `long int *' now.Roland McGrath
[BFD] (host_bfd_arch_info): New variable. [BFD] (host_bfd): Initialize `arch_info' member to its address. (check) [BFD]: Use bfd_arch_get_compatible properly, rather than the nonexistent bfd_arch_compatible. (main) [BFD]: Fill in host_bfd.arch_info instead of old `obj_machine' and `obj_archiecture' members, which BFD no longer has.
1994-12-12(struct execdata): New members `headbuf', `file_data', `optimal_block'.Roland McGrath
(load_section): Copy data from U->file_data if that is nonnull. Use new subfunction `write_to_task' that handles non-page aligned sections. (input_room): Fix EOF check. Use io_read if no memory object. (prepare): New function, broken out of check. Initialize E->file_data and E->optimal_block. Set E->stream.__seen bit. (check): No longer take FILE arg. Use E->file_data if nonnull; else read from stream if no memory object. (finish_mapping): Reset members after deallocating resources. (finish): Likewise. Call fclose. Don't deallocate E->header if it points to &E->headbuf or E->file_data. (check_gzip): New function, implements executing gzip'd binaries. (do_exec): Call prepare before check. Call check_gzip if file format unrecognized.
1994-11-09(set_active_trans): Don't deallocate EXECNODE here to work around aMichael I. Bushnell
ufs bug.
1994-11-09Include <hurd/paths.h> and <fcntl.h>.Michael I. Bushnell
(set_active_trans): Declare as void.
1994-11-09(set_active_trans): New function.Michael I. Bushnell
(S_exec_init): Call set_active_trans.
