* file-exec.c (diskfs_S_file_exec): Give the new peropen for the exec
server O_EXEC permission as well as O_READ.

|
* dir-lookup.c (diskfs_S_dir_lookup): Follow symlink despite flags if
MUSTBEDIR is set (i.e. there was a trailing slash).
|
|
|
|
* rdwr-internal.c (_diskfs_rdwr_internal): Short-circuit return for
zero-length transfer to avoid side effects, as POSIX requires.

Rewrite of a fix provided by Bill White <bill.white@griggsinst.com>:
* fhandle.h (union diskfs_fhandle): Replaces struct diskfs_fhandle.
Use a union element of char[28] to ensure size requirement.
* fsys-getfile.c (diskfs_S_fsys_getfile): Update uses for new type.
* file-getfh.c (diskfs_S_file_getfh): Likewise.
|
|
|
|
* io-read.c (diskfs_S_io_read): Add braces to silence gcc
warning.
|
|
|
|
* priv.h (_diskfs_chroot_directory): Remove const from type.
* init-startup.c (_diskfs_chroot_directory): Likewise.

* disk-pager.c (fault_handler): Put more detail in assert failures.
|
|
|
|
* node-nput.c (diskfs_nput): Call diskfs_set_node_times before
diskfs_lost_hardrefs. This should address the late mtime update
bug reported and investigated by Mark Kettenis.

|
|
* sync-interval.c (periodic_sync): With diskfs_fsys_lock reader lock
held, check _diskfs_diskdirty and don't sync if not dirty.

* 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.

|
|
|
|
* 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.

* node-times.c (diskfs_set_node_times): Don't implement
_diskfs_noatime here.

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,

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).
