Using the standard macro makes it easier to move code into common, as TALLOC_ARRAY isn't standard talloc.

2011-02-26dirfd doesn't exist in some platforms.Jeremy Allison1-2/+4
Hack that should get the buildfarm back to green. Ensure dirfd() needs to be defined before we properly return fdopendir. This will do until we get a proper dirfd() defined in libreplace. From http://www.gnu.org/software/hello/manual/gnulib/dirfd.html This function is missing on some platforms: AIX 7.1, HP-UX 11, OSF/1 5.1, Solaris 10, mingw. Jeremy.

2010-06-09s3: fix calculation of st_blocks in init_stat_ex_from_statBjörn Jacke1-1/+1
this is just relevant for the very rare systems that don't have the st_blocks struct member. This is a fixup of the fix for bug 7474. Thanks to Joachim Schmitz for spotting this!

this is in preparation for other preallocation methods to be introduced.

2009-12-04s3: check if glibc has broken posix_fallocateBjörn Jacke1-1/+1
2009-12-02s3: prefer posix_fallocate for doing "strict allocate"Björn Jacke1-0/+14
posix_fallocate is more efficient than manual zero'ing the file. When preallocation in kernel space is supported it's extremely fast. Support for preallocation at fs layer via posix_fallocate and fallocate at kernel site can be found in Linux kernel 2.6.23/glibc 2.10 with ext4, XFS and OCFS2. Other systems that I know of which support fast preallocation in kernel space are AIX 6.1 with JFS2 and recent Solaris versions with ZFS maybe UFS2, too. People who have a system with preallocation in kernel space might want to set "strict allocate = yes". This reduces file fragentation and it's also safer for setups with quota being turned on. As of today most systems still don't have preallocation in kernel space, and that's why "strict allocate = no" will stay the default for now.
2009-11-29s3: Pass the "fake dir create times" parameter to sys_*statVolker Lendecke1-10/+14
Step 0 to restore it as a per-share paramter
2009-11-17Remove "store create time" code, cause create time to be storedJeremy Allison1-0/+7
in the "user.DOSATTRIB" EA. From the docs: In Samba 3.5.0 and above the "user.DOSATTRIB" extended attribute has been extended to store the create time for a file as well as the DOS attributes. This is done in a backwards compatible way so files created by Samba 3.5.0 and above can still have the DOS attribute read from this extended attribute by earlier versions of Samba, but they will not be able to read the create time stored there. Storing the create time separately from the normal filesystem meta-data allows Samba to faithfully reproduce NTFS semantics on top of a POSIX filesystem. Passes make test but will need more testing. Jeremy.

2009-07-08Rename update_stat_ex_writetime() -> update_stat_ex_mtime()Jeremy Allison1-2/+2
to better describe what we're doing here. Jeremy
2009-07-08The migration to struct stat_ex broke the calculation ofJeremy Allison1-14/+58
create time from the existing timestamps (for systems that need to do this). Once the write time is changed via a sticky write, the create time might need to be recalculated. To do this I needed to add a bool into struct stat_ex to remember if the st_ex_btime field was calculated, or read from the OS. Also fixed the returning of modified write timestamps in the return from NTCreateX, SMBattr and SMBattrE (which weren't taking into account the modified timestamp stored in the open file table). Attempting to fix an issue with Excel 2003 and offline files. Volker and Metze, please review. Jeremy

2009-05-26Introduce "struct stat_ex" as a replacement for SMB_STRUCT_STATVolker Lendecke1-9/+216
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.

2009-02-23Refactored sys_fork() and sys_pid() into shared util librarySteven Danneman1-29/+0
This fixes a bug in 116ce19b, where we didn't clear the pid cache in become_daemon() and thus the /var/run/smbd.pid didn't match the actual pid of the parent process. Currently S4 will clear the pid cache on fork but doesn't yet take advantage of the pid cache by using sys_pid() instead of the direct get_pid().
