2016-12-12ubifs: Implement UBIFS_FLG_DOUBLE_HASHRichard Weinberger
This feature flag indicates that all directory entry nodes have a 32bit cookie set and therefore UBIFS is allowed to perform lookups by hash. Signed-off-by: Richard Weinberger <richard@nod.at>

Signed-off-by: Richard Weinberger <richard@nod.at>
2016-12-12ubifs: Add full hash lookup supportRichard Weinberger
UBIFS stores a 32bit hash of every file, for traditional lookups by name this scheme is fine since UBIFS can first try to find the file by the hash of the filename and upon collisions it can walk through all entries with the same hash and do a string compare. When filesnames are encrypted fscrypto will ask the filesystem for a unique cookie, based on this cookie the filesystem has to be able to locate the target file again. With 32bit hashes this is impossible because the chance for collisions is very high. Do deal with that we store a 32bit cookie directly in the UBIFS directory entry node such that we get a 64bit cookie (32bit from filename hash and the dent cookie). For a lookup by hash UBIFS finds the entry by the first 32bit and then compares the dent cookie. If it does not match, it has to do a linear search of the whole directory and compares all dent cookies until the correct entry is found. Signed-off-by: Richard Weinberger <richard@nod.at>

tnc_read_hashed_node() is a better name since we read a node by a given hash, not a name. Signed-off-by: Richard Weinberger <richard@nod.at>

2016-12-12ubifs: Make r5 hash binary string awareRichard Weinberger
As of now all filenames known by UBIFS are strings with a NUL terminator. With encrypted filenames a filename can be any binary string and the r5 function cannot search for the NUL terminator. UBIFS always knows how long a filename is, therefore we can change the hash function to iterate over the filename length to work correctly with binary strings.

2016-12-12ubifs: Introduce new data node field, compr_sizeRichard Weinberger
When data of a data node is compressed and encrypted we need to store the size of the compressed data because before encryption we may have to add padding bytes. For the new field we consume the last two padding bytes in struct ubifs_data_node. Two bytes are fine because the data length is at most 4096. Signed-off-by: Richard Weinberger <richard@nod.at>
2016-12-12ubifs: Enforce crypto policy in mmapRichard Weinberger
We need this extra check in mmap because a process could gain an already opened fd. Signed-off-by: Richard Weinberger <richard@nod.at>
2016-12-12ubifs: Massage assert in ubifs_xattr_set() wrt. fscryptoRichard Weinberger
When we're creating a new inode in UBIFS the inode is not yet exposed and fscrypto calls ubifs_xattr_set() without holding the inode mutex. This is okay but ubifs_xattr_set() has to know about this. Signed-off-by: Richard Weinberger <richard@nod.at>

2016-12-12ubifs: Enforce crypto policy in ->link and ->renameRichard Weinberger
When a file is moved or linked into another directory its current crypto policy has to be compatible with the target policy. Signed-off-by: Richard Weinberger <richard@nod.at>
2016-12-12ubifs: Implement file open operationRichard Weinberger
We need ->open() for files to load the crypto key. If the no key is present and the file is encrypted, refuse to open. Signed-off-by: Richard Weinberger <richard@nod.at>

2016-12-12ubifs: Use dirty_writeback_interval value for wbuf timerRafał Miłecki
Right now wbuf timer has hardcoded timeouts and there is no place for manual adjustments. Some projects / cases many need that though. Few file systems allow doing that by respecting dirty_writeback_interval that can be set using sysctl (dirty_writeback_centisecs). Lowering dirty_writeback_interval could be some way of dealing with user space apps lacking proper fsyncs. This is definitely *not* a perfect solution but we don't have ideal (user space) world. There were already advanced discussions on this matter, mostly when ext4 was introduced and it wasn't behaving as ext3. Anyway, the final decision was to add some hacks to the ext4, as trying to fix whole user space or adding new API was pointless. We can't (and shouldn't?) just follow ext4. We can't e.g. sync on close as this would cause too many commits and flash wearing. On the other hand we still should allow some trade-off between -o sync and default wbuf timeout. Respecting dirty_writeback_interval should allow some sane cutomizations if used warily.

2016-12-12ubifs: Drop softlimit and delta fields from struct ubifs_wbufRafał Miłecki
Values of these fields are set during init and never modified. They are used (read) in a single function only. There isn't really any reason to keep them in a struct.

[Problem] In some USB DACs, a terrible pop noise comes to be heard at the start of DSD playback (in the following situations). - play first DSD track - change from PCM track to DSD track - change from DSD64 track to DSD128 track (and etc...) - seek DSD track - Fast-Forward/Rewind DSD track [Cause] At the start of playback, there is a little silence.

2016-12-12IB/rxe: Hold refs when running taskletsAndrew Boyer
It might be possible for all of a QP's references to be dropped while one of that QP's tasklets is running. For example, the completer might run during QP destroy. If qp->valid is false, it will drop all of the packets on the resp_pkts list, potentially removing the last reference. Then it tries to advance the SQ consumer pointer. If the SQ's buffer has already been destroyed, the system will panic. To be safe, hold a reference on the QP for the duration of each tasklet.

2016-12-12IB/rxe: Wait for tasklets to finish before tearing down QPAndrew Boyer
The system may crash when a malformed request is received and the error is detected by the responder. NodeA: $ ibv_rc_pingpong -g 0 -d rxe0 -i 1 -n 1 -s 50000 NodeB: $ ibv_rc_pingpong -g 0 -d rxe0 -i 1 -n 1 -s 1024 <NodeA_ip> The responder generates a receive error on node B since the incoming SEND is oversized. If the client tears down the QP before the responder or the completer finish running, a page fault may occur. The fix makes the destroy operation spin until the tasks complete, which appears to be original intent of the design.

2016-12-12IB/rxe: Add support for IB_CQ_REPORT_MISSED_EVENTSAndrew Boyer
Peek at the CQ after arming it so that we can return a hint. This avoids missed completions due to a race between posting CQEs and arming the CQ.

2016-12-12IB/rxe: Don't update the response PSN unless it's going forwardsAndrew Boyer
A client might post a read followed by a send. The partner receives and acknowledges both transactions, posting an RCQ entry for the send, but something goes wrong with the read ACK. When the client retries the read, the partner's responder processes the duplicate read but incorrectly resets the PSN to the value preceding the original send. When the duplicate send arrives, the responder cannot tell that it is a duplicate, so the responder generates a duplicate RCQ entry, confusing the client.
