[ Upstream commit 7b0c03ec ] This patch adds a new device-tree property that allows to specify the dma protection control bits for the all of the DMA controller's channel uniformly. Setting the "correct" bits can have a huge impact on the PPC460EX and APM82181 that use this DMA engine in combination with a DesignWare' SATA-II core (sata_dwc_460ex driver). In the OpenWrt Forum, the user takimata reported that: |It seems your patch unleashed the full power of the SATA port. |Where I was previously hitting a really hard limit at around |82 MB/s for reading and 27 MB/s for writing, I am now getting this: | |root@OpenWrt:/mnt# time dd if=/dev/zero of=tempfile bs=1M count=1024 |1024+0 records in |1024+0 records out |real 0m 13.65s |user 0m 0.01s |sys 0m 11.89s | |root@OpenWrt:/mnt# time dd if=tempfile of=/dev/null bs=1M count=1024 |1024+0 records in |1024+0 records out |real 0m 8.41s |user 0m 0.01s |sys 0m 4.70s | |This means: 121 MB/s reading and 75 MB/s writing! | |The drive is a WD Green WD10EARX taken from an older MBL Single. |I repeated the test a few times with even larger files to rule out |any caching, I'm still seeing the same great performance. OpenWrt is |now completely on par with the original MBL firmware's performance. Another user And.short reported: |I can report that your fix worked! Boots up fine with two |drives even with more partitions, and no more reboot on |concurrent disk access! A closer look into the sata_dwc_460ex code revealed that the driver did initally set the correct protection control bits. However, this feature was lost when the sata_dwc_460ex driver was converted to the generic DMA driver framework.

[ Upstream commit 627469e4 ] The function coh901318_alloc_chan_resources() calls spin_lock_irqsave() before calling coh901318_config(). But coh901318_config() calls spin_lock_irqsave() again in its definition, which may cause a double-lock bug. Because coh901318_config() is only called by coh901318_alloc_chan_resources(), the bug fix is to remove the calls to spin-lock and -unlock functions in coh901318_config(). Signed-off-by:

[ Upstream commit 896585d4 ] When we add a new IPv6 address, we should also join corresponding solicited-node multicast address, unless the interface has IFF_NOARP flag, as function addrconf_join_solict() did. But if we remove IFF_NOARP flag later, we do not do dad and add the mcast address. So we will drop corresponding neighbour discovery message that came from other nodes. A typical example is after creating a ipvlan with mode l3, setting up an ipv6 address and changing the mode to l2. Then we will not be able to ping this address as the interface doesn't join related solicited-node mcast address. Fix it by re-doing dad when interface changed IFF_NOARP flag. Then we will add corresponding mcast group and check if there is a duplicate address on the network. Reported-by:

[ Upstream commit b1bbc1a6 ] We have to choose different configuration and different firmwares depending on the external RF module that is installed. Since the external module is not represented in the PCI IDs, we need to change the configuration at runtime, after checking the RF ID of the module installed. We have a bit of a mess in the code that does this, because it applies cfg's according to the RF ID only, ignoring the integrated module that is in use. Fix that for some devices by adding correct configurations for them and not ignoring the integrated module's type when making the decision. Signed-off-by:

[ Upstream commit 8c110d43 ] When we read the EOF page of the file via readpages, we need to zero the region beyond EOF that we either do not read or should not contain data so that mmap does not expose stale data to user applications. However, iomap_adjust_read_range() fails to detect EOF correctly, and so fsx on 1k block size filesystems fails very quickly with mapreads exposing data beyond EOF. There are two problems here. Firstly, when calculating the end block of the EOF byte, we have to round the size by one to avoid a block aligned EOF from reporting a block too large. i.e. a size of 1024 bytes is 1 block, which in index terms is block 0. Therefore we have to calculate the end block from (isize - 1), not isize. The second bug is determining if the current page spans EOF, and so whether we need split it into two half, one for the IO, and the other for zeroing. Unfortunately, the code that checks whether we should split the block doesn't actually check if we span EOF, it just checks if the read spans the /offset in the page/ that EOF sits on. So it splits every read into two if EOF is not page aligned, regardless of whether we are reading the EOF block or not. Hence we need to restrict the "does the read span EOF" check to just the page that spans EOF, not every page we read. This patch results in correct EOF detection through readpages: xfs_vm_readpages: dev 259:0 ino 0x43 nr_pages 24 xfs_iomap_found: dev 259:0 ino 0x43 size 0x66c00 offset 0x4f000 count 98304 type hole startoff 0x13c startblock 1368 blockcount 0x4 iomap_readpage_actor: orig pos 323584 pos 323584, length 4096, poff 0 plen 4096, isize 420864 xfs_iomap_found: dev 259:0 ino 0x43 size 0x66c00 offset 0x50000 count 94208 type hole startoff 0x140 startblock 1497 blockcount 0x5c iomap_readpage_actor: orig pos 327680 pos 327680, length 94208, poff 0 plen 4096, isize 420864 iomap_readpage_actor: orig pos 331776 pos 331776, length 90112, poff 0 plen 4096, isize 420864 iomap_readpage_actor: orig pos 335872 pos 335872, length 86016, poff 0 plen 4096, isize 420864 iomap_readpage_actor: orig pos 339968 pos 339968, length 81920, poff 0 plen 4096, isize 420864 iomap_readpage_actor: orig pos 344064 pos 344064, length 77824, poff 0 plen 4096, isize 420864 iomap_readpage_actor: orig pos 348160 pos 348160, length 73728, poff 0 plen 4096, isize 420864 iomap_readpage_actor: orig pos 352256 pos 352256, length 69632, poff 0 plen 4096, isize 420864 iomap_readpage_actor: orig pos 356352 pos 356352, length 65536, poff 0 plen 4096, isize 420864 iomap_readpage_actor: orig pos 360448 pos 360448, length 61440, poff 0 plen 4096, isize 420864 iomap_readpage_actor: orig pos 364544 pos 364544, length 57344, poff 0 plen 4096, isize 420864 iomap_readpage_actor: orig pos 368640 pos 368640, length 53248, poff 0 plen 4096, isize 420864 iomap_readpage_actor: orig pos 372736 pos 372736, length 49152, poff 0 plen 4096, isize 420864 iomap_readpage_actor: orig pos 376832 pos 376832, length 45056, poff 0 plen 4096, isize 420864 iomap_readpage_actor: orig pos 380928 pos 380928, length 40960, poff 0 plen 4096, isize 420864 iomap_readpage_actor: orig pos 385024 pos 385024, length 36864, poff 0 plen 4096, isize 420864 iomap_readpage_actor: orig pos 389120 pos 389120, length 32768, poff 0 plen 4096, isize 420864 iomap_readpage_actor: orig pos 393216 pos 393216, length 28672, poff 0 plen 4096, isize 420864 iomap_readpage_actor: orig pos 397312 pos 397312, length 24576, poff 0 plen 4096, isize 420864 iomap_readpage_actor: orig pos 401408 pos 401408, length 20480, poff 0 plen 4096, isize 420864 iomap_readpage_actor: orig pos 405504 pos 405504, length 16384, poff 0 plen 4096, isize 420864 iomap_readpage_actor: orig pos 409600 pos 409600, length 12288, poff 0 plen 4096, isize 420864 iomap_readpage_actor: orig pos 413696 pos 413696, length 8192, poff 0 plen 4096, isize 420864 iomap_readpage_actor: orig pos 417792 pos 417792, length 4096, poff 0 plen 3072, isize 420864 iomap_readpage_actor: orig pos 420864 pos 420864, length 1024, poff 3072 plen 1024, isize 420864 As you can see, it now does full page reads until the last one which is split correctly at the block aligned EOF, reading 3072 bytes and zeroing the last 1024 bytes. The original version of the patch got this right, but it got another case wrong. The EOF detection crossing really needs to the the original length as plen, while it starts at the end of the block, will be shortened as up-to-date blocks are found on the page. This means "orig_pos + plen" no longer points to the end of the page, and so will not correctly detect EOF crossing. Hence we have to use the length passed in to detect this partial page case: xfs_filemap_fault: dev 259:1 ino 0x43 write_fault 0 xfs_vm_readpage: dev 259:1 ino 0x43 nr_pages 1 xfs_iomap_found: dev 259:1 ino 0x43 size 0x2cc00 offset 0x2c000 count 4096 type hole startoff 0xb0 startblock 282 blockcount 0x4 iomap_readpage_actor: orig pos 180224 pos 181248, length 4096, poff 1024 plen 2048, isize 183296 xfs_iomap_found: dev 259:1 ino 0x43 size 0x2cc00 offset 0x2cc00 count 1024 type hole startoff 0xb3 startblock 285 blockcount 0x1 iomap_readpage_actor: orig pos 183296 pos 183296, length 1024, poff 3072 plen 1024, isize 183296 Heere we see a trace where the first block on the EOF page is up to date, hence poff = 1024 bytes. The offset into the page of EOF is 3072, so the range we want to read is 1024 - 3071, and the range we want to zero is 3072 - 4095. You can see this is split correctly now. This fixes the stale data beyond EOF problem that fsx quickly uncovers on 1k block size filesystems. Signed-off-by:

[ Upstream commit 4721a601 ] When doing direct IO to a pipe for do_splice_direct(), then pipe is trivial to fill up and overflow as it can only hold 16 pages. At this point bio_iov_iter_get_pages() then returns -EFAULT, and we abort the IO submission process. Unfortunately, iomap_dio_rw() propagates the error back up the stack. The error is converted from the EFAULT to EAGAIN in generic_file_splice_read() to tell the splice layers that the pipe is full. do_splice_direct() completely fails to handle EAGAIN errors (it aborts on error) and returns EAGAIN to the caller. copy_file_write() then completely fails to handle EAGAIN as well, and so returns EAGAIN to userspace, having failed to copy the data it was asked to. Avoid this whole steaming pile of fail by having iomap_dio_rw() silently swallow EFAULT errors and so do short reads. To make matters worse, iomap_dio_actor() has a stale data exposure bug bio_iov_iter_get_pages() fails - it does not zero the tail block that it may have been left uncovered by partial IO. Fix the error handling case to drop to the sub-block zeroing rather than immmediately returning the -EFAULT error. Signed-off-by:

[ Upstream commit b450672f ] If we are doing sub-block dio that extends EOF, we need to zero the unused tail of the block to initialise the data in it it. If we do not zero the tail of the block, then an immediate mmap read of the EOF block will expose stale data beyond EOF to userspace. Found with fsx running sub-block DIO sizes vs MAPREAD/MAPWRITE operations. Fix this by detecting if the end of the DIO write is beyond EOF and zeroing the tail if necessary. Signed-off-by:

[ Upstream commit 0929d858 ] When we write into an unwritten extent via direct IO, we dirty metadata on IO completion to convert the unwritten extent to written. However, when we do the FUA optimisation checks, the inode may be clean and so we issue a FUA write into the unwritten extent. This means we then bypass the generic_write_sync() call after unwritten extent conversion has ben done and we don't force the modified metadata to stable storage. This violates O_DSYNC semantics. The window of exposure is a single IO, as the next DIO write will see the inode has dirty metadata and hence will not use the FUA optimisation. Calling generic_write_sync() after completion of the second IO will also sync the first write and it's metadata. Fix this by avoiding the FUA optimisation when writing to unwritten extents.

[ Upstream commit 02968ccf ] Now sctp increases sk_wmem_alloc by 1 when doing set_owner_w for the skb allocked in sctp_packet_transmit and decreases by 1 when freeing this skb. But when this skb goes through networking stack, some subcomponents might change skb->truesize and add the same amount on sk_wmem_alloc. However sctp doesn't know the amount to decrease by, it would cause a leak on sk->sk_wmem_alloc and the sock can never be freed. Xiumei found this issue when it hit esp_output_head() by using sctp over ipsec, where skb->truesize is added and so is sk->sk_wmem_alloc. Since sctp has used sk_wmem_queued to count for writable space since Commit cd305c74 ("sctp: use sk_wmem_queued to check for writable space"), it's ok to fix it by counting sk_wmem_alloc by skb truesize in sctp_packet_transmit.

The bug here is that we wouldn't sync per-cpu counters into global ones if there was an update of numa_stats for higher cpus. Highly theoretical one though because it is much more probable that zone_stats are updated so we would refresh anyway. So I wouldn't bother to mark this for stable, yet something nice to fix.

However, some mailbox calls use larger data buffers than the maximum allowed in that change. This fix therefor moves from using fixed buffers to kmalloc to ensure all sizes are catered for. There is some documentation, which is somewhat out of date, on the mailbox calls here : https://github.com/raspberrypi/firmware/wiki/Mailbox-property-interface Fixes: a1547e0b ("firmware: raspberrypi: Remove VLA usage") Signed-off-by:

[ Upstream commit 688cd642 ] adt7316_i2c_read function nowhere sets the data field. It is necessary to have an appropriate value for it. Hence, assign the value stored in 'ret' variable to data field. This is an ancient bug, and as no one seems to have noticed, probably no sense in applying it to stable. Signed-off-by:

[ Upstream commit 7ed07855 ] When attempting to setup up a gpio hog, device probing will repeatedly fail with -EPROBE_DEFERED errors. It is caused by a circular dependency between the gpio and pinctrl frameworks. If the gpio-ranges property is present in device tree, then the gpio framework will handle the gpio pin registration and eliminate the circular dependency. See Christian Lamparter's commit a86caa9b ("pinctrl: msm: fix gpio-hog related boot issues") for a detailed commit message that explains the issue in much more detail. The code comment in this commit came from Christian's commit. I did not test this change against any hardware supported by this particular driver, however I was able to validate this same fix works for pinctrl-spmi-gpio.c using a LG Nexus 5 (hammerhead) phone.
