* exec/exec.c (do_exec): If the formatted task name exceeds
TASK_NAME_SIZE, abbreviate it.

* exec/Makefile (exec_startup-MIGSFLAGS): New variable.
* exec/execmutations.h: Add mutators for exec_startup_t.

* exec/priv.h (bootinfo_t): New type declaration to appease mig.

The name will be used in error messages printed by the kernel. This
makes attributing the errors to processes possible.
* exec/exec.c (do_exec): Set the name of the new task.

Remove support for transparently ungziping executables from the exec
server. The code in question makes the exec server unnecessarily
complex and since the exec server is an essential process, crashing it
makes /hurd/init crash the whole system.
Since the gzip code is not thread-safe, all access to it is
serialized, so there is a trivial way for one user to delay another
users gzipped executables for some unspecified time.
This can be accomplished by padding any program with easily compressed
data, zipping it and executing it. Using such a program as an passive
translator and then triggering its execution by the filesystem
translator also stalls any requests to that filesystem (observed using
the libdiskfs-based ext2fs).
Since compressed executables cannot be mapped into the memory, they
have to be uncompressed into allocated memory first. This is slower
and any user with access to the exec server can make it allocate
arbitrary amounts of memory. If the Hurd had proper memory accounting,
this would probably be a way around it.
So the compression support in exec seemingly creates various issues
for little value, at least with the abundance of nonvolatile memory
available today.

Remove support for transparently unbzip2ing executables from the exec
server. The code in question makes the exec server unnecessarily
complex and since the exec server is an essential process, crashing it
makes /hurd/init crash the whole system.
Since the bzip2 code is not thread-safe, all access to it is
serialized, so there is a trivial way for one user to delay another
users bzip2ed executables for some unspecified time.

data, zipping it and executing it. Using such a program as an passive

Keep track of the range where executable segments are mapped into
memory and hand that information over to the proc server.
* exec/priv.h (struct execdata): Add {start,end}_code.
* exec/exec.c (prepare): Initialize {start,end}_code.
(load_section): Update {start,end}_code.
(do_exec): Use proc_set_code to hand {start,end}_code to the proc server.

This commit removes the parts of the exec server that were once using
the Binary File Descriptor library.
As I understand it, the BFD code stopped working because it uses stdio
streams and the glue code for that has never been ported to libio. The
code has been #ifdefed out ever since. It may or may not work in its
current state, so it is removed. If someone is interested, it can
always be recovered from the version control system.
* exec/exec.c: Remove all BFD related code.
* exec/priv.h: Likewise.
* TODO: Remove the corresponding item.

This code was meant to allow the user to specify alternative exec
servers using an environment variable. The Hurd uses the file system
as namespace for server lookups, so the proper way to use one's own
exec server seems to be the remap translator.
* exec/exec.c (S_exec_exec): Remove unused code.
|
|
* exec/exec.c (check_section): Remove unused variable.

Makefiles, headers, types, macros and function calls are renamed where
appropriate.
Most of this work was done by Barry deFreese and Thomas DiModica.

(map_buffer, map_filepos, map_set_fsize): New macros for accessing
those or stream.
[! EXECDATA_STREAM] (map_fsize, map_vsize): Define using new members.
* exec.c (map): Rewritten purely using those accessor macros.
(input_room): Set the __target, __bufp, __error, and __eof members,
which are no longer set by map.
[! EXECDATA_STREAM] (prepare_stream, prepare_in_memory): Make no-ops.
(input_room, close_exec_stream, fake_seek, prepare_stream,
prepare_in_memory): Conditionalize these defns on [EXECDATA_STREAM].
(load_section): Always use map instead of stdio.
Replace bcopy with memcpy.
(check_gzip: zipread): Rewrite using map instead of stdio.
(check_bzip2: zipread): Likewise.
|
|
* exec.c (map): Made global.
* priv.h: Declare it.
(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.
|
|
* exec.c (servercopy): Removed unused variable.
|
|
* exec.c (load_section): Fix typos in last change.
|
|
* 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.
|
|
* exec.c (check_elf): Call elf_machine_matches_host instead of
comparing against elf_machine.
(load_section): #if 0 out no-op code that uses elf_machine.
* priv.h (elf_machine_matches_host): Declare it.
(elf_machine, mach_host_elf_machine): Remove decls.
* main.c (main) [!BFD]: Don't call mach_host_elf_machine.
(elf_machine): Variable removed.
* exec.c (map): Don't cast arg to munmap to vm_address_t.
|
|
* core.c (core_dump_task): Use munmap instead of vm_deallocate,
when it's from our own task.
* elfcore.c: Likewise.
* exec.c (load_section): Likewise.
(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.
|
|
* exec.c (map): Fix mapping calls to use F->__offset consistently
instead of F->__target.
|
|
* do-bunzip2.c: New file.
* exec.c (check_bzip2): New function.
(BZIP2): New cpp symbol. If defined, bunzip2 engine is enabled.
* Makefile (bzip2-objects): New variable.
(OBJS): Add bzip2-objects.
(CPPFLAGS): Add -DBZIP2.
|
|
* exec.c (do_exec): Implement EXEC_SIGTRAP flag.
|
|
* 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.
|
|
* exec.c (do_exec): Set boot->phdr_addr and boot->user_entry after
loading, to addresses adjusted for actual run-time load address.
|
|
* 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 <thomas@gnu.ai.mit.edu>
* exec.c: Don't include <hurd/shared.h> any more.
* main.c (S_exec_init): New arg syntax of trivfs_open.
|
|
* 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.
