2018-10-20Revert "neighbour: force neigh_invalidate when NUD_FAILED update is from admin"Roopa Prabhu1-2/+1
This reverts commit 8e326289e3069dfc9fa9c209924668dd031ab8ef. This patch results in unnecessary netlink notification when one tries to delete a neigh entry already in NUD_FAILED state. Found this with a buggy app that tries to delete a NUD_FAILED entry repeatedly. While the notification issue can be fixed with more checks, adding more complexity here seems unnecessary. Also, recent tests with other changes in the neighbour code have shown that the INCOMPLETE and PROBE checks are good enough for the original issue.

2018-10-20net/ipv6: Fix index counter for unicast addresses in in6_dump_addrsDavid Ahern1-2/+4
The loop wants to skip previously dumped addresses, so loops until current index >= saved index. If the message fills it wants to save the index for the next address to dump - ie., the one that did not fit in the current message. Currently, it is incrementing the index counter before comparing to the saved index, and then the saved index is off by 1 - it assumes the current address is going to fit in the message. Change the index handling to increment only after a succesful dump.

2018-10-20blkcg: reassociate bios when make_request() is called recursivelyDennis Zhou3-0/+24

2018-10-20parisc: Optimze cache flush algorithmsJohn David Anglin2-20/+229
The attached patch implements three optimizations: 1) Loops in flush_user_dcache_range_asm, flush_kernel_dcache_range_asm, purge_kernel_dcache_range_asm, flush_user_icache_range_asm, and flush_kernel_icache_range_asm are unrolled to reduce branch overhead. 2) The static branch prediction for cmpb instructions in pacache.S have been reviewed and the operand order adjusted where necessary. 3) For flush routines in cache.c, we purge rather flush when we have no context. The pdc instruction at level 0 is not required to write back dirty lines to memory. This provides a performance improvement over the fdc instruction if the feature is implemented. Version 2 adds alternative patching. The patch provides an average improvement of about 2%. Signed-off-by: John David Anglin <[email protected]> Signed-off-by: Helge Deller <[email protected]>

2018-10-20net: fix pskb_trim_rcsum_slow() with odd trim offsetDimitris Michailidis1-2/+3
We've been getting checksum errors involving small UDP packets, usually 59B packets with 1 extra non-zero padding byte. netdev_rx_csum_fault() has been complaining that HW is providing bad checksums. Turns out the problem is in pskb_trim_rcsum_slow(), introduced in commit 88078d98d1bb ("net: pskb_trim_rcsum() and CHECKSUM_COMPLETE are friends"). The source of the problem is that when the bytes we are trimming start at an odd address, as in the case of the 1 padding byte above, skb_checksum() returns a byte-swapped value. We cannot just combine this with skb->csum using csum_sub(). We need to use csum_block_sub() here that takes into account the parity of the start address and handles the swapping. Matches existing code in __skb_postpull_rcsum() and esp_remove_trailer().

If the guest kernel happened to be built with KVM_INDIRECT_VECTORS, we go on to allocate a slot, memcpy() the empty workaround in and do the appropriate cache maintenance. This works as we always tell memcpy() the range is 0, so it never accesses the NULL src pointer, but we still do the cache maintenance.

When the last CPU in an rdt_domain goes offline, its rdt_domain struct gets freed. Current pseudo-locking code is unaware of this scenario and tries to dereference the freed structure in a few places. Add checks to prevent pseudo-locking code from doing this. While further work is needed to seamlessly restore resource groups (not just pseudo-locking) to their configuration when the domain is brought back online, the immediate issue of invalid pointers is addressed here.

Add support to use McSPI controller as SPI slave.

2018-10-19spi: omap2-mcspi: Set FIFO DMA trigger level to word lengthVignesh R1-19/+7
McSPI has 32 byte FIFO in Transmit-Receive mode. Current code tries to configuration FIFO watermark level for DMA trigger to be GCD of transfer length and max FIFO size which would mean trigger level may be set to 32 for transmit-receive mode if length is aligned. This does not work in case of SPI slave mode where FIFO always needs to have data ready whenever master starts the clock. With DMA trigger size of 32 there will be a small window during slave TX where DMA is still putting data into FIFO but master would have started clock for next byte, resulting in shifting out of stale data. Similarly, on Slave RX side there may be RX FIFO overflow Fix this by setting FIFO watermark for DMA trigger to word length. This means DMA is triggered as soon as FIFO has space for word length bytes and DMA would make sure FIFO is almost always full therefore improving FIFO occupancy in both master and slave mode.

2018-10-19drm/sun4i: Fix an ulong overflow in the dotclock driverBoris Brezillon1-1/+11
The calculated ideal rate can easily overflow an unsigned long, thus making the best div selection buggy as soon as no ideal match is found before the overflow occurs.

NAND core changes: - Two batchs of cleanups of the NAND API, including: * Deprecating a lot of interfaces (now replaced by ->exec_op()). * Moving code in separate drivers (JEDEC, ONFI), in private files (internals), in platform drivers, etc. * Functions/structures reordering. * Exclusive use of the nand_chip structure instead of the MTD one all across the subsystem. - Addition of the nand_wait_readrdy/rdy_op() helpers. Raw NAND controllers drivers changes: - Various coccinelle patches. - Marvell: * Use regmap_update_bits() for syscon access. * More documentation. * BCH failure path rework. * More layouts to be supported. * IRQ handler complete() condition fixed. - Fsl_ifc: * SRAM initialization fixed for newer controller versions. - Denali: * Fix licenses mismatch and use a SPDX tag. * Set SPARE_AREA_SKIP_BYTES register to 8 if unset. - Qualcomm: * Do not include dma-direct.h. - Docg4: * Removed. - Ams-delta: * Use of a GPIO lookup table * Internal machinery changes. Raw NAND chip drivers changes: - Toshiba: * Add support for Toshiba memory BENAND * Pass a single nand_chip object to the status helper. - ESMT: * New driver to retrieve the ECC requirements from the 5th ID byte.
