[PATCH] nvmem: apple-spmi-nvmem: wrap regmap calls to satisfy CFI

by Jens Reidel

The Apple SPMI NVMEM driver previously cast regmap_bulk_read/write to void * when assigning them to nvmem_config's reg_read/reg_write function pointers. This cast breaks the expected function signature of nvmem_reg_read_t and nvmem_reg_write_t. With CFI enabled, indirect calls through these pointers fail: CFI failure at nvmem_reg_write+0x194/0x1e4 (target: regmap_bulk_write+0x0/0x2c8; expected type: 0x83a189c3) ...

[REGRESSION] nfs: Large amounts of GETATTR calls after file renaming on v5.10.241

by Ahmed, Aaron

Hi, We have had customers report a regression on kernels versions 5.10.241 and above in which file renaming causes large amounts of GETATTR calls to made due to inode revalidation. This regression was pinpointed via bisected to commit 7378c7adf31d ("NFS: Don't set NFS_INO_REVAL_PAGECACHE in the inode cache validity") which is a backport of 36a9346c2252 (“NFS: Don't set NFS_INO_REVAL_PAGECACHE in the inode cache validity”). We were able to reproduce It with this script: REPRO_PATH=/mnt/efs/repro do_read() { for x in {1..50} do cat $1 > /dev/null done grep GETATTR /proc/self/mountstats } echo foo > $REPRO_PATH/bar echo "After create, before read:" grep GETATTR /proc/self/mountstats echo "First read:" do_read $REPRO_PATH/bar echo "Sleeping 5s, reading again (should look the same):" sleep 5 do_read $REPRO_PATH/bar mv $REPRO_PATH/bar $REPRO_PATH/baz echo "Moved file, reading again:" do_read $REPRO_PATH/baz echo "Immediately performing another set of reads:" do_read $REPRO_PATH/baz echo "Cleanup, removing test file" rm $REPRO_PATH/baz which performs a few read/writes. On kernels without the regression the number of GETATTR calls remains the same while on affected kernels the amount increases after reading renamed file. This original commit comes from a series of patches providing attribute revalidation updates [1]. However, many of these patches are missing in v.5.10.241+. Specifically, 13c0b082b6a9 (“NFS: Replace use of NFS_INO_REVAL_PAGECACHE when checking cache validity”) seems like a prerequisite patch and would help remedy the regression. #regzbot introduced: 7378c7adf31d Thanks, Aaron Ahmed [1] https://lore.kernel.org/all/20210414134353.11860-1-trondmy@kernel.org/ Signed-off-by: Aaron Ahmed <aarnhahmd(a)amazon.com>

Because the tests are expecting a long on-going connection, and they are not waiting for the end of the transfer, it is fine to make the connection longer. This connection will be killed at the end, after the verifications, so making it longer doesn't change anything, apart from avoid it to end before the end of the verifications To play it safe, all endpoints tests not waiting for the end of the transfer are now sharing a longer file (128KB) at slow speed.

[PATCH] net: dsa: microchip: fix mdio parent bus reference leak

by Ma Ke

In ksz_mdio_register(), when of_mdio_find_bus() is called to get the parent MDIO bus, it increments the reference count of the underlying device. However, the reference are not released in error paths or during switch teardown, causing a reference leak. Add put_device() in the error path of ksz_mdio_register() and ksz_teardown() to release the parent bus. Found by code review.

[PATCH v3] powerpc, mm: Fix mprotect on book3s 32-bit

by Dave Vasilevsky

On 32-bit book3s with hash-MMUs, tlb_flush() was a no-op. This was unnoticed because all uses until recently were for unmaps, and thus handled by __tlb_remove_tlb_entry(). After commit 4a18419f71cd ("mm/mprotect: use mmu_gather") in kernel 5.19, tlb_gather_mmu() started being used for mprotect as well. This caused mprotect to simply not work on these machines: int *ptr = mmap(NULL, 4096, PROT_READ|PROT_WRITE, MAP_PRIVATE|MAP_ANONYMOUS, -1, 0); *ptr = 1; // force HPTE to be created mprotect(ptr, 4096, PROT_READ); *ptr = 2; // should segfault, but succeeds Fixed by making tlb_flush() actually flush TLB pages. This finally agrees with the behaviour of boot3s64's tlb_flush().
