This patch introduces
struct stat_ex {
dev_t st_ex_dev;
ino_t st_ex_ino;
mode_t st_ex_mode;
nlink_t st_ex_nlink;
uid_t st_ex_uid;
gid_t st_ex_gid;
dev_t st_ex_rdev;
off_t st_ex_size;
struct timespec st_ex_atime;
struct timespec st_ex_mtime;
struct timespec st_ex_ctime;
struct timespec st_ex_btime; /* birthtime */
blksize_t st_ex_blksize;
blkcnt_t st_ex_blocks;
};
typedef struct stat_ex SMB_STRUCT_STAT;
It is really large because due to the friendly libc headers playing macro
tricks with fields like st_ino, so I renamed them to st_ex_xxx.
Why this change? To support birthtime, we already have quite a few #ifdef's at
places where it does not really belong. With a stat struct that we control, we
can consolidate the nanosecond timestamps and the birthtime deep in the VFS
stat calls.
At this moment it is triggered by a request to support the birthtime field for
GPFS. GPFS does not extend the system level struct stat, but instead has a
separate call that gets us the additional information beyond posix. Without
being able to do that within the VFS stat calls, that support would have to be
scattered around the main smbd code.
It will very likely break all the onefs modules, but I think the changes will
be reasonably easy to do.
This creates a broken registry that can only be fixed with
tdbtool, since the '/' sign is used as a key separator after
normalization at a lower level.
This makes e.g. "net conf setparm abc/def comment xyz" fail with
WERR_INVALID_PARAM, which is much more desirable than a broken
registry.tdb.

and loop from the end to the beginning so that we don't need
to rehash the subkeys...
This gets "net conf drop" with 2000 shares down to 14 seconds
on my box.

This removes many loops over all the arrays
(from regsubkey_ctr_key_exists) and thus
reduces "net conf drop" from 1m55 to 48seconds
and "net conf import" from 1m55 to 58 seconds
for 2000 shares on my box.

This reverts commit a13f065bad.
This fix is reverted, because the speedup is going to move
further down into reg_objects.c. The unsorted list of subkey names
is going to be indexed: This O(n^2) search bites us in more places.
This re-establishes the abstraction of reg_objects.c.
