* shutdown.c (diskfs_shutdown): Sync and set the clean flag even if we
don't shut down. Thus a disk that was in use but hadn't been touched
recently needn't necessarily be checked after a system crash.
|
|
|
|
* dir-lookup.c (diskfs_S_dir_lookup: short_circuited_callback1): Fix
type of arg `argz_len' to use size_t *.
|
|
* dir-lookup.c (diskfs_S_dir_lookup): Don't require the node to be
a directory in the null pathname case. (Thus reverting one of the
changes of June 15, 1994.)

|
|
|
* lookup.c (diskfs_lookup): If NAME is empty, return an error.
|
|
* file-get-trans.c (diskfs_S_file_get_translator) [S_ISCHR ||
S_ISBLK]: Free BUF after using it. Reported by Katusya Tanaka
(wyvern@pb3.so-net.ne.jp).
|
|
* file-reparent.c (diskfs_S_file_reparent): Use diskfs_nrele
instead of protocol-violating up-tree lock.
* peropen-rele.c (diskfs_release_peropen): Likewise.

* init-init.c (nosuid, noexec): New variables, initialized to zero.

--no-exec.
* opts-common.c (diskfs_common_options): Add --no-suid and

H->noexec.

Turn off synchronous mode when setting a sync interval.

* diskfs.h (diskfs_hard_readonly): New variable.
(diskfs_readonly): Doc change.
* readonly.c (diskfs_readonly): Provide initialized declaration.
(diskfs_check_readonly): If we cannot write the media and so we
switch to readonly, set diskfs_hard_readonly too.
(diskfs_set_readonly): If diskfs_hard_readonly is set, then
inhibit any attempt to clear readonly status.

Initialize the ROOT_PARENT, SHADOW_ROOT, and SHADOW_ROOT_PARENT fields.
|
|
|
|
Use fshelp_translated rather than fshelp_fetch_control.
|
|
* Makefile (LCLHDRS): Add fhandle.h.
|
|
* file-chmod.c (diskfs_S_file_chmod): Turn off S_ITRANS bits too.
|

error before ENOTDIR-when-not-dir.

|
Pass CRED's shadow root inode number to fshelp_get_identity when creating a
shadow root fsid, not INUM.
|
|
|
|
|
|
Mark shadow roots with S_IROOT.
|
|
Return different fsys ids for different shadow roots.
|
|
|
|
Use CRED->po as LOOKUPCRED's po, so that root detection works (and doesn't
crash).
|
|
Don't deadlock if PO's shadow_root is also it's node.
|
|
Don't release a reference to any old shadow_root if it was == NODE.
Don't aquire a new reference for NODE.
|
|
Support reading from sylinks.
|
|
Allow symlinks to be opened for O_READ.
