[PATCH v5] spi: spi-mem: Adjust op len based on message/transfer size limitations

by Chuanhua Han

We need that to adjust the len of the 2nd transfer (called data in spi-mem) if it's too long to fit in a SPI message or SPI transfer. Fixes: c36ff266dc82 ("spi: Extend the core to ease integration of SPI memory controllers") Cc: <stable(a)vger.kernel.org> Signed-off-by: Chuanhua Han <chuanhua.han(a)nxp.com> Suggested-by: Boris Brezillon <boris.brezillon(a)bootlin.com> --- Changes in v5: -Add the validation check after the op->data.nbytes assignment -Assign the "len" variable after defining it Changes in v4: -Rename variable name "opcode_addr_dummy_sum" to "len". -The comparison of "spi_max_message_size(mem->spi)" and "len" was removed. -Adjust their order when comparing the sizes of "spi_max_message_size(mem->spi)" and "len" -Changing the "unsigned long" type in the code to "size_t" Changes in v3: -Rename variable name "val" to "opcode_addr_dummy_sum". -Place the legitimacy of the transfer size(i.e., "spi_max_message_size(mem->spi)" and -"opcode_addr_dummy_sum") into "if (! ctlr - > mem_ops | |! ctlr-> mem_ops->exec_op) {" structure and add "spi_max_transfer_size(mem->spi) and opcode_addr_dummy_sum". -Adjust the formatting alignment of the code. -"(unsigned long)op->data.nbytes" was modified to "(unsigned long)(op->data.nbytes)". Changes in v2: -Place the adjusted transfer bytes code in spi_mem_adjust_op_size() and check spi_max_message_size(mem->spi) value before subtracting opcode, addr and dummy bytes. -Change the code from fsl-espi controller to generic code(The adjustment of spi transmission length was originally modified in the "drivers/spi/spi-fsl-espi.c" file, and now the adjustment of transfer length is made in the "drivers/spi/spi-mem.c" file) drivers/spi/spi-mem.c | 16 ++++++++++++++++ 1 file changed, 16 insertions(+) diff --git a/drivers/spi/spi-mem.c b/drivers/spi/spi-mem.c index 990770d..6184fa1 100644 --- a/drivers/spi/spi-mem.c +++ b/drivers/spi/spi-mem.c @@ -328,10 +328,26 @@ EXPORT_SYMBOL_GPL(spi_mem_exec_op); int spi_mem_adjust_op_size(struct spi_mem *mem, struct spi_mem_op *op) { struct spi_controller *ctlr = mem->spi->controller; + size_t len; + + len = sizeof(op->cmd.opcode) + op->addr.nbytes + op->dummy.nbytes; if (ctlr->mem_ops && ctlr->mem_ops->adjust_op_size) return ctlr->mem_ops->adjust_op_size(mem, op); + if (!ctlr->mem_ops || !ctlr->mem_ops->exec_op) { + if (len > spi_max_transfer_size(mem->spi)) + return -EINVAL; + + op->data.nbytes = min3((size_t)(op->data.nbytes), + spi_max_transfer_size(mem->spi), + spi_max_message_size(mem->spi) - + len); + + if (!op->data.nbytes) + return -EINVAL; + } + return 0; } EXPORT_SYMBOL_GPL(spi_mem_adjust_op_size); -- 2.7.4

[BUG] madvise05 leads kernel panic on 4.9.122

by Yang Shi

Hi folks, I just ran some regression test on stable 4.9.122 with LTP. madvise05 triggers the below kernel panic: [ 6785.089994] BUG: unable to handle kernel paging request at ffffeaff44488020 [ 6785.097952] IP: [] page_remove_rmap+0x27/0x580 [ 6785.104810] PGD 0 [ 6785.106859] [ 6785.108526] Oops: 0000 [#1] SMP [ 6785.112029] Modules linked in: mptctl(E) mptbase(E) tun(E) fuse(E) vfat(E) fat(E) btrfs(E) xor(E) raid6_pq(E) xfs(E) [ 6785.123905] CPU: 14 PID: 77983 Comm: madvise05 Tainted: G E 4.9.122-001.ali3000_nightly_cov_20180820_193.test.alios7.x86_64 #1 [ 6785.137880] Hardware name: Dell Inc.

So, it looks it is caused by the L1TF patches on the stable tree. And, the madvise05 test case can be simplified to the below test program: #include <sys/mman.h> #include <stdio.h> void main() { void *addr; int err; addr = mmap(NULL, 32 * 1024 * 1024, PROT_READ, MAP_PRIVATE | MAP_ANONYMOUS | MAP_POPULATE, -1, 0); if (addr == MAP_FAILED) { printf("mmap failed\n"); return; } err = mprotect(addr, 32 * 1024 * 1024, PROT_NONE); if (err < 0) { printf("mprotect failed\n"); return; } munmap(addr, 32 * 1024 * 1024); } You may be already aware of this problem or any hint is appreciated. Thanks, Yang
