This makes sure the functions in libthreads properly override the stubs in libports with the new dynamic linker semantics in glibc 2.2. 2000-07-20 Thomas Bushnell, BSG * hashexec.c (check_hashbang): Count characters in interp correctly. Fix from Kalle Olavi Niemitalo . 2000-03-23 Mark Kettenis * exec.c (do_exec): Set interp.file to MACH_PORT_NULL before the first `goto out'. 2000-03-20 Roland McGrath * main.c (trivfs_allow_open): Initialize to zero.

The non-BFD exec server is now completely independent of stdio magic; it uses only those interfaces documented in the C library manual, which are provided both by old GNU stdio and by GNU libio. Resurrecting the BFD exec server will require using magic again, for which libio-specific magic needs to be written. * exec.c [! EXECDATA_STREAM] (prepare_stream): Replace no-op with real function to initialize map_* members to zero. * priv.h (EXECDATA_STREAM): New macro, always defined for now. (struct execdata) [! EXECDATA_STREAM]: Add members map_buffer, map_bsize, map_fsize, map_filepos in place of stream. (map_buffer, map_filepos, map_set_fsize): New macros for accessing those or stream. [!

(map_fsize, map_vsize): New macros for accessing state set up by map. * hashexec.c (check_hashbang): Use map and copying operations rather than stdio to extract the first line from the file. Move finish call to immediately after reading the line. * exec.c (map): If E->file_data is set, diagnose EOF before going to direct io_read. (prepare_in_memory): New function, broken out of check_gzip before last change. (check_gzip, check_bzip2): Use it. * exec.c (prepare_stream): New function, broken out of prepare. (prepare): Call it. [_STDIO_USES_IOSTREAM]: Do #error if this is defined. (map, input_room, close_exec_stream, fake_seek, prepare_stream): Conditionalize all these definitions on [! _STDIO_USES_IOSTREAM]. Only map and prepare_stream are called from elsewhere in the code. (check_gzip): Don't reinitialize E->stream, since it will in fact not be used again. (check_bzip2): Likewise. 2000-03-09 Roland McGrath * hostarch.c (elf_machine_matches_host): Don't recognize EM_486, since newer 's don't define it any more. 2000-02-27 Roland McGrath * hashexec.c (check_hashbang: user_fd): Add a user ref to DTABLE[FD] send right, because caller (hurd_file_name_lookup internals) will consume one. * hashexec.c (check_hashbang): When dealloc'ing DTABLE ports, optimize out syscall for null ports. 1999-11-08 Roland McGrath * exectrans.c (trivfs_support_write, trivfs_support_exec): Variables removed. (trivfs_allow_open): Set to just O_READ. 1999-09-09 Roland McGrath * Makefile (exec.static-LDFLAGS): Variable removed. 1999-07-17 Roland McGrath * exec.c (servercopy): Removed unused variable. 1999-07-11 Roland McGrath * exec.c (load_section): Fix typos in last change. 1999-07-11 Thomas Bushnell, BSG * exec.c (load_section): Use mmap instead of vm_allocate when allocating in mach_task_self (). (servercopy): Likewise. (do_exec): Likewise. * hashexec.c (check_hashbang): Likewise. 1999-07-10 Roland McGrath * hostarch.c (mach_host_elf_machine): Replaced with ... (elf_machine_matches_host): New function. Instead of returning an ELF EM_* code, take one and check if it matches the host; operate only on mach_host_self(), cache results, Grok CPU_TYPE_{I486,PENTIUM,PENTIUMPRO} to accept EM_386 or EM_486. Grok POWERPC, ALPHA, HPPA types. * exec.c (check_elf): Call elf_machine_matches_host instead of comparing against elf_machine.

(map): Likewise. (close_exec_stream): Likewise. (finish_mapping): Likewise. (load): Likewise. (do_exec): Likewise. (S_exec_setexecdata): Likewise. * hashexec.c (check_hashbang): Likewise. * main.c (deadboot): Likewise. 1999-06-04 Roland McGrath * exec.c (map): Fix mapping calls to use F->__offset consistently instead of F->__target. 1999-05-16 Roland McGrath * hashexec.c (check_hashbang): Fix bug in last change. 1999-05-15 Roland McGrath * hashexec.c (check_hashbang): Trim trailing blanks after interpreter argument. 1998-09-05 OKUJI Yoshinori * do-bunzip2.c: New file. * exec.c (check_bzip2): New function.

Use assert_perror on getting the host-priv port and on startup_essential_task, since init will hang until we've done made that RPC. 1998-12-26 Roland McGrath * exec.c (do_exec): Fix conditional for cleaning up INTERP, from nonnull E.interp.section to nonnull INTERP.file. If we failed to open the interpreter file, INTERP.file will be null and the rest of INTERP will be uninitialized. 1998-12-21 Roland McGrath * main.c (S_exec_init): Don't call set_active_trans. (set_active_trans): Function removed. * Makefile (HURDLIBS): Add missing implied library deps. 1998-11-25 Mark Kettenis * main.c (S_exec_init): Call _hurd_proc_init with new args set to zero. * hashexec.c (check_hashbang): Fix typo: interplen -> interp_len. Thu Nov 5 15:26:50 1998 Thomas Bushnell, BSG * hashexec.c (check_hashbang): Keep INTERP_LEN with the correct value (bytes of memory holding INTERP) for later use. (check_hashbang: setup_args): Set argv[0] from the interpreter name, not copied from the existing command line. 1998-10-26 Roland McGrath * hashexec.c: Use mach_* instead of __mach_*. 1998-07-15 Roland McGrath * exec.c (do_exec): Set boot->phdr_addr and boot->user_entry after loading, to addresses adjusted for actual run-time load address.

Mon Nov 18 17:45:48 1996 Thomas Bushnell, n/BSG * exec.c (load_section): If ANYWHERE, then make sure ADDR starts out at least past the first page, so that we don't take it. Then the library can (if desired) make the page no-access. Fri Nov 15 17:34:23 1996 Thomas Bushnell, n/BSG * exec.c: Don't include any more. * main.c (S_exec_init): New arg syntax of trivfs_open. Mon Oct 7 21:31:25 1996 Thomas Bushnell, n/BSG * exec.c (fake_seek): New function. (prepare): Initialize E->stream.__io_funcs.seek to fake_seek; this is called now that stdio doesn't assume it always knows the file position.

Only declare host_bfd_arc_info, and bfd_host_bfd if BFD. If not BFD, give typedef for asection. * main.c: Only define host_bfd_arch_info, host_bfd, and bfd_mach_host_arch_mach if BFD. (main): Only call bfd_mach_most_arch_mach if BFD. Call mach_host_elf_machine. * hostarch.c (bfd_mach_host_arch_mach): Only define if BFD. Delete arg E_MACHINE. All callers changed.

Bushnell, p/BSG * gzip.h (basename): Comment out declaration; it conflicts with libc's. * exec.c (do_exec): If secure, set the owner with proc_setowner. 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.

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. Use envz_get() to search the environment. * exec.c (S_exec_exec): Use envz_get() to search the environment. Thu Jan 4 11:30:15 1996 Roland McGrath * exec.c (safe_bzero): Rewritten using hurd_catch_signal. * hashexec.c (check_hashbang): Rearrange arg frobbing code somewhat to use hurd_catch_signal instead of old preemption interface. Fri Dec 29 15:54:06 1995 Miles Bader * exec.c (do_exec): 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. Fri Dec 15 01:53:07 1995 Roland McGrath * exec.c (map): Rearrange code to fix some bugs and not remap unless necessary. (input_room): Simplify. (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.

Thu Jun 8 02:57:28 1995 Roland McGrath * exec.c (struct execdata.info.elf): Add members `anywhere' and `loadbase'. (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. Mon Jun 5 06:42:33 1995 Roland McGrath * exec.c: Majorly revamped: Now supports the ELF format directly.

(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. * Makefile (vpath lib%.a): Add search path. (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.

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.
