* s3/smbd: fix FSCTL_SET_SPARSE permission checksDavid Disseldorp2015-03-091-2/+7
| | | | | | | | | | | | On Windows servers (tested against Windows Server 2008 & 2012) the FSCTL_SET_SPARSE ioctl is processed if FILE_WRITE_DATA, FILE_WRITE_ATTRIBUTES _or_ SEC_FILE_APPEND_DATA permissions are granted on the open file-handle. Fix Samba such that it matches this behaviour, rather than only checking for FILE_WRITE_DATA or FILE_WRITE_ATTRIBUTES.

| | | | | | | | | | | This change implements support for FSCTL_QUERY_ALLOCATED_RANGES using the SEEK_HOLE/SEEK_DATA functionality of lseek(). Files marked non-sparse are always reported by the ioctl as fully allocated, regardless of any potential "strict allocate = no" savings.

"SEEK_DATA and SEEK_HOLE are nonstandard extensions also present in Solaris, FreeBSD, and DragonFly BSD; they are proposed for inclusion in the next POSIX revision (Issue 8)." With Linux they are supported on: - Btrfs (since Linux 3.1) - OCFS (since Linux 3.2) - XFS (since Linux 3.5) - ext4 (since Linux 3.8) - tmpfs (since Linux 3.8) Signed-off-by: David Disseldorp <ddiss@samba.org> Reviewed-by: Jeremy Allison <jra@samba.org>
* smbd/ioctl: add FSCTL_SET_ZERO_DATA supportDavid Disseldorp2015-03-091-1/+111
| | | | | | | | | | | | | | | | | | | | | | FSCTL_SET_ZERO_DATA can be used in two ways. - When requested against a file marked as sparse, it provides a mechanism for requesting that the server deallocate the underlying disk space for the corresponding zeroed range. - When requested against a non-sparse file, it indicates that the server should allocate and zero the corresponding range. Both use cases can be handled in Samba using fallocate(). The Linux specific FALLOC_FL_PUNCH_HOLE flag can be used to deallocate the underlying disk space. After doing so, a normal fallocate() call can be used to ensure that the zeroed range is allocated on non-sparse files. FSCTL_SET_ZERO_DATA requests must not result in a change to the file size. The FSCTL_SET_ZERO_DATA handler always calls fallocate() with the KEEP_SIZE flag set, ensuring that Samba meets this requirement.

* s3/vfs: change fallocate mode flags from enum->uint32_tDavid Disseldorp2015-03-0912-44/+43
| | | | | | | | | | | | | | | | | | | | The Linux fallocate syscall offers a mode parameter which can take the following flags: FALLOC_FL_KEEP_SIZE FALLOC_FL_PUNCH_HOLE (since 2.6.38) FALLOC_FL_COLLAPSE_RANGE (since 3.15) FALLOC_FL_ZERO_RANGE (since 3.14) The flags are not exclusive, e.g. FALLOC_FL_PUNCH_HOLE must be specified alongside FALLOC_FL_KEEP_SIZE. Samba currently takes a vfs_fallocate_mode enum parameter for the VFS fallocate hook, taking either an EXTEND_SIZE or KEEP_SIZE value. This commit changes the fallocate hook such that it accepts a uint32_t flags parameter, in preparation for PUNCH_HOLE and ZERO_RANGE support.

| | | | | | | | | | | | | | | | | | The trigger for this is that Coverity got confused by the dual use of &xid as an array with the implicit length equality between wb_sids2xids_send and the array passed in to wb_sids2xids_recv for the result. I don't want to start doing things just for the Coverity scan, but this makes the code clearer to me by removing this implicit expected array length equality.

* s3:smbprofile: Replace sysv shmem with tdbVolker Lendecke2015-03-067-110/+446
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | What? This patch gets rid of the central shared memory segment referenced by "profile_p". Instead, every smbd gets a static profile_area where it collects profiling data. Once a second, every smbd writes this profiling data into a record of its own in a "smbprofile.tdb". smbstatus -P does a tdb_traverse on this database and sums up what it finds. Why? At least in my perception sysv IPC has not the best reputation on earth. The code before this patch uses shmat(). Samba ages ago has developed a good abstraction of shared memory: It's called tdb. The main reason why I started this is that I have a request to become more flexible with profiling data. Samba should be able to collect data per share or per user, something which is almost impossible to do with a fixed structure. My idea is to for example install a profile area per share and every second marshall this into one tdb record indexed by share name. smbstatus -P would then also collect the data and either aggregate them or put them into individual per-share statistics. This flexibility in the data model is not really possible with one fixed structure. But isn't it slow? Well, I don't think so. I can't really prove it, but I do believe that on large boxes atomically incrementing a shared memory value for every SMB does show up due to NUMA effects. With this patch the hot code path is completely process-local. Once a second every smbd writes into a central tdb, this of course does atomic operations. But it's once a second, not on every SMB2 read. There's two places where I would like to improve things: With the current code all smbds wake up once a second. With 10,000 potentially idle smbds this will become noticable. That's why the current only starts the timer when something has changed. The second place is the tdb traverse: Right now traverse is blocking in the sense that when it has to switch hash chains it will block. With mutexes, this means a syscall. I have a traverse light in mind that works as follows: It assumes a locked hash chain and then walks the complete chain in one run without unlocking in between. This way the caller can do nonblocking locks in the first round and only do blocking locks in a second round. Also, a lot of syscall overhead will vanish. This way smbstatus -P will have almost zero impact on normal operations.
