* sync-interval.c (periodic_sync): With diskfs_fsys_lock reader lock
held, check _diskfs_diskdirty and don't sync if not dirty.
|
|
|
|
* opts-std-startup.c (TOGGLE): Fix `off' case.
Reported by Kalle Olavi Niemitalo <tosi@ees2.oulu.fi>.

|
* io-pathconf.c (diskfs_S_io_pathconf): Cap diskfs_name_max to size
representable in struct dirent.d_namlen.
(diskfs_S_io_pathconf): Always return 1 for _PC_NO_TRUNC, since we
always constrain diskfs_name_max.
|
|
|
|
* lookup.c (diskfs_lookup): Enforce diskfs_name_max limit for CREATE
and RENAME, returning ENAMETOOLONG for violations.
* io-pathconf.c (diskfs_S_io_pathconf): _PC_NO_TRUNC controlled by
diskfs_name_max setting.
|
|
|
|
* diskfs.h (diskfs_name_max): Declare new variable.
* io-pathconf.c (diskfs_S_io_pathconf): Use it for _PC_NAME_MAX,
capping it to 1024.
|
|
|
|
* opts-std-runtime.c (parse_opt: ARGP_KEY_INIT): Initialize H->noatime.
|
|
|
|
* dir-readdir.c (diskfs_S_dir_readdir): Take new DATA_DEALLOC param.
|
|
|
|
* lookup.c (diskfs_lookup): Rewrite code from last change, which had
typos (and then I just decided to change the details of the string
diddling).
|
|
* lookup.c (diskfs_lookup): NAME is no longer const. Update
documentation Strip leading and trailing slashes from NAME before
using it.
* diskfs.h (diskfs_lookup): NAME is no longer const.
Update documentation.
1999-10-05 Thomas Bushnell, BSG <tb@mit.edu>
* priv.h (CHANGE_NODE_FIELD): Use diskfs_check_readonly instead of
directly reading diskfs_readonly.
|
|
* node-times.c (diskfs_set_node_times): Don't implement
_diskfs_noatime here.
* conch-fetch.c (iohelp_fetch_shared_data): Don't update
dn_set_atime on affected node if _diskfs_noatime.

|
|
|
|
* node-times.c (diskfs_set_node_times): If _diskfs_noatime is set and
neither NP->dn_set_mtime nor NP->dn_set_ctime is set, clear
NP->dn_set_atime. Short-circuit return if none of dn_set_?time set.
* opts-common.c (diskfs_common_options): Include "priv.h".
Add aliases --ro/--rw for -r/-w. Add alias --nosuid for --no-suid,
--noexec for --no-exec. Move --suid-ok, --exec-ok here from ...
* opts-std-runtime.c (std_runtime_options): ... here.
(struct parse_hook): New member `noatime'.
(set_opts): Use H->noatime to set _diskfs_noatime.
(parse_opt): Grok -A and OPT_ATIME to set/clear H->noatime.
(OPT_ATIME): New macro.
(OPT_SUID_OK, OPT_EXEC_OK): Moved to ...
* priv.h: ... here.
(diskfs_common_options): Add const to decl.
* opts-std-startup.c (parse_startup_opt): Grok OPT_SUID_OK,
OPT_EXEC_OK, -A, and OPT_ATIME.
* init-init.c (_diskfs_noatime): New variable.
(_diskfs_nosuid, _diskfs_noexec): Use uninitialized defns.
* opts-append-std.c (diskfs_append_std_options): Add --no-atime if
_diskfs_noatime is set.
|
|
|
|
* io-pathconf.c: Include <unistd.h>.
(diskfs_S_io_pathconf): Provide real definition.
|
|
* io-map-segment.c: New file. Guts from io-map.c.
* io-map.c (diskfs_S_io_map): Just call diskfs_S_io_map_segment.
* diskfs.h (diskfs_get_filemap): New parameter `index'.
* rdwr-internal.c (_diskfs_rdwr_internal): Pass additional
parameter to diskfs_get_filemap.
* Makefile (IOSRCS): Add io-map-segment.c.
|
|
|
|
* dir-rmdir.c (diskfs_S_dir_rmdir): Fix bugs in last change.
Replace label `out' with local inline function `done'.
Don't try diskfs_nput (NP) when NP is null.
|
|
|
|
* dir-link.c (diskfs_S_dir_link): Fix error checks on ports.
If DIRCRED (receiver port) is bad, return EOPNOTSUPP.
If FILECRED (argument port) is bad, return EXDEV (after EROFS check).
|
|
|
|
* boot-start.c (diskfs_S_exec_startup_get_info): Typo in last change.
|
|
* boot-start.c (diskfs_S_exec_startup_get_info): Use mmap instead
of vm_allocate.
(diskfs_S_fsys_init): Likewise.
* file-get-trans.c (diskfs_S_file_get_translator): Likewise.
* file-getfh.c (diskfs_S_file_getfh): Likewise.
* io-read.c (diskfs_S_io_read): Likewise.
|
|
|
|
* priv.h: Add #include <sys/mman.h> for munmap decl.
|
|
* node-nputl.c (diskfs_nput_light): Fix typo in function
declaration. Reported by Yamashita TAKAO
(jargon@lares.dti.ne.jp).
|
|
* file-get-trans.c (diskfs_S_file_get_translator): Use munmap
instead of vm_deallocate.
* io-read.c (diskfs_S_io_read): Likewise.
* protid-rele.c (diskfs_protid_rele): Likewise.
|
|
* node-nref.c: New file; guts from diskfs.h.
* node-nput.c: Likewise.
* node-nrele.c: Likewise.
* node-nrefl.c: Likewise.
* node-nputl.c: Likewise.
* node-nrelel.c: LIkewise.
* diskfs.h (diskfs_nref, diskfs_nput, diskfs_nrele,
diskfs_nref_light, diskfs_nput_light, diskfs_nrele_light): Replace
inline definitions with ordinary declarations.
(DISKFS_EI): Removed macro.
* diskfs.c: Deleted file.
* Makefile (OTHERSRCS): Added node-nref.c, node-nput.c
node-nrele.c, node-nrefl.c, node-nputl.c, node-nrelel.c. Removed
diskfs.c.

* hyper.c (diskfs_readonly_changed): Adjust whether the store
should permit writes too.
|
|
* lookup.c (diskfs_lookup): If we get an error from
fshelp_checkdirmod, clear *NP as well as returning the error.
Use diskfs_nrele instead of diskfs_nput in case *NP and DP are
the same.

* dir-rmdir.c (diskfs_S_dir_rmdir): Reorganized to make clearer;
several little buglets fixed too.
|
|
* dir-rmdir.c (diskfs_S_dir_rmdir): Reorganized to make clearer.
|
|
* sync-default.c (diskfs_default_sync_interval): Reduce to five
seconds. Hardware is much different than when Unix originally
picked thirty, plus we manage VM differently than the Unix buffer
cache did, and tend to delay many more writes than Unix did.
|
|
|
|
* file-get-trans.c (diskfs_S_file_get_translator): Fix type cast in
last change.
|
|
|
|
* file-get-trans.c (diskfs_S_file_get_translator): If we return an
error, vm_deallocate any vm_allocated memory.
From Mark Kettenis <kettenis@gnu.org>.

|
|
|
* boot-start.c (diskfs_start_bootstrap): Pass environment collected
from `environ' on to init. The kernel can send more parameters
through this way without us knowing about them specifically.
|
|
|
|
* console.c (diskfs_console_stdio): If there is an fd 2 that appears
to work, just leave it as is and dup2 it to fd 1 as well.
|
|
|
|
* file-chown.c (diskfs_S_file_chown): Fix last change: not just
permission check, actually don't make the change if value is -1.
