[ Upstream commit b8db1592 ] We fail to advance the read pointer when reading the stat.oh field that identifies the lock-holder in a TEST result. This turns out not to matter if the server is knfsd, which always returns a zero-length field. But other servers (Ganesha is an example) may not do this. The result is bad values in fcntl F_GETLK results. Fix this. Signed-off-by:

[ Upstream commit 9ccb6456 ] Currently the null check on key is occurring after the strcasecmp on the key, hence there is a potential null pointer dereference on key.

[ Upstream commit c44768a3 ] On T4 and later sparc64 cpus we can use the fused compare and branch instruction. However, it can only be used if the branch destination is in the range of a signed 10-bit immediate offset. This amounts to 1024 instructions forwards or backwards. After the commit referenced in the Fixes: tag, the largest possible size program seen by the JIT explodes by a significant factor. As a result of this convergance takes many more passes since the expanded "BPF_LDX | BPF_MSH | BPF_B" code sequence, for example, contains several embedded branch on condition instructions. On each pass, as suddenly new fused compare and branch instances become valid, this makes thousands more in range for the next pass. And so on and so forth. This is most greatly exemplified by "BPF_MAXINSNS: exec all MSH" which takes 35 passes to converge, and shrinks the image by about 64K. To decrease the cost of this number of convergance passes, do the convergance pass before we have the program image allocated, just like other JITs (such as x86) do.

[ Upstream commit eafcd8e3 ] Current core-pkey selftest fails if the test runs without privileges to write into the core pattern file (/proc/sys/kernel/core_pattern). This causes the test to fail and give the impression that the subsystem being tested is broken, when, in fact, the test is being executed without the proper privileges. This is the current error: test: core_pkey tags: git_version:v4.19-3-g9e3363be9bce-dirty Error writing to core_pattern file: Permission denied failure: core_pkey This patch simply skips this test if it runs without the proper privileges, avoiding this undesired failure.

[ Upstream commit 5249497a ] Some ptrace selftests are passing input operands using a constraint that can allocate any register for the operand, and using these registers on load/store operations. If the register allocated by the compiler happens to be zero (r0), it might cause an invalid memory address access, since load and store operations consider the content of 0x0 address if the base register is r0, instead of the content of the r0 register. For example: r1 := 0xdeadbeef r0 := 0xdeadbeef ld r2, 0(1) /* will load into r2 the content of r1 address */ ld r2, 0(0) /* will load into r2 the content of 0x0 */ In order to avoid this possible problem, the inline assembly constraint should be aware that these registers will be used as a base register, thus, r0 should not be allocated. Other than that, this patch removes inline assembly operands that are not used by the tests. Signed-off-by:

[ 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:
