* exec/exec.c (load_section): Call i`hurd_safe_copyin' instead of `memcpy'.
Handle error case.
(check_gzip): Likewise.
(check_bzip2): Likewise.
|
|
* exec/exec.c (check_gzip.zipread): Add `n' to `zipread_pos' to fix infinite loop.
(check_bzip2.zipread): Likewise.
(check_gzip): Set `file_data' and `file_size' fields after calling `finish'
instead of before.
(check_bzip2): Likewise.
|
|
* exec/exec.c (map): When e->file_data is not NULL, return it plus
`posn'.
(prepare_in_memory): Call prepare_stream to clear stream positions.
|
|
* exec/Makefile (SRCS): Refer to `$(gzip-sources)' and
`$(bzip2-sources)' instead of listing files individually.
(gzip-sources, bzip2-sources): New variable.
(gzip-objects, bzip2-objects): Derive from the above variables.
|
|
* exec/hashexec.c (check_hashbang): Set `e->error' to 0 before
calling map(). On error, check `e->error' instead of `errno', and
default `e->error' to ENOEXEC.
|
|
* exec/exec.c (do_exec): Do not deallocate oldtask when
newtask != oldtask before the `out:' label since it is done
again after it.
|
|
* exec.c (finish): Set FILE_DATA and MAP_BUFFER members of E to NULL
after freeing them.

* exec.c (prepare): Call PREPARE_STREAM earlier to permit calling
finish_mapping on E even after errors, as is already done in do_exec.
|

|
|
casting `time_value *' into `struct timeval *'.
(dump_core): Reimplement timeradd instead of casting `time_value *'
into `struct timeval *'.

|
* exec.c (check_elf_phdr): Return early on setting ENOEXEC.
Only touch E->info.elf.phdr_addr once, on the PT_LOAD segment that
actually contains the e_phoff location in the file.
(do_exec): If E.info.elf.phdr_addr is zero, don't set BOOT->phdr_size.
|
|
|
|
|
|
* priv.h (struct execdata.info.elf): New field `phdr_addr'.
* exec.c (check_elf): Set E->info.elf.phdr_addr here from e_phoff.
(check_elf_phdr): Don't check for PT_PHDR, remove last two args.
(do_exec): Update callers. Set BOOT->phdr_addr and BOOT->phdr_size
using info saved by check_elf.
|
|
|
|
* exec.c (servercopy): Change signature to avoid casted arguments.
Update callers.
(do_exec, S_exec_setexecdata): Update callers.
|
|
|
|
* priv.h (struct execdata.info.elf): Add `execstack' flag.
* exec.c (check_elf_phdr): Set it according to PT_GNU_STACK's PF_X
flag bit. If no PT_GNU_STACK, default to set.
(do_exec): If flag is clear, remove execute permission from stack.
|

* elfcore.c (dump_core): Include null terminator in note name size,
and round up to four byte alignment.
(dump_core: write_note): Don't round OFFSET after each partial write.
(dump_core): Don't round up to page size before writing notes.
Do round up to page size for offset of each PT_LOAD region.

* elfcore.c [i386_THREAD_STATE] (fetch_thread_regset): The two types
are not actually identical, must rearrange some members a little.
|
|
|
|
* priv.h (trivfs_protid_t): Type removed (now in trivfs.h).
