This provides +additional protection and allows to detect data corruption on the I2C bus. + +SMBus block reads support variable length reads. The first byte in the read +message is the number of available data bytes. + +The combination of PEC and block read is currently not supported by the +Cadence I2C driver. + * When PEC is enabled the maximum transfer length for block reads + increases from 33 to 34 bytes. + * The I2C core smbus emulation layer relies on the driver updating the + `i2c_msg` `len` field with the number of received bytes. The updated + length is used when checking the PEC. + +Add support to the Cadence I2C driver for handling SMBus block reads with +PEC. To determine the maximum transfer length uses the initial `len` value +of the `i2c_msg`. When PEC is enabled this will be 2, when it is disabled +it will be 1. + +Once a read transfer is done also increment the `len` field by the amount +of received data bytes. + +This change has been tested with a UCM90320 PMBus power monitor, which +requires block reads to access certain data fields, but also has PEC +enabled by default. + +Fixes: df8eb5691c48 ("i2c: Add driver for Cadence I2C controller") +Signed-off-by: Lars-Peter Clausen +Tested-by: Shubhrajyoti Datta +Signed-off-by: Wolfram Sang +Signed-off-by: Sasha Levin +--- + drivers/i2c/busses/i2c-cadence.c | 10 +++++++++- + 1 file changed, 9 insertions(+), 1 deletion(-) + +diff --git a/drivers/i2c/busses/i2c-cadence.c b/drivers/i2c/busses/i2c-cadence.c +index 512c61d31fe5..bce7bf93d62a 100644 +--- a/drivers/i2c/busses/i2c-cadence.c ++++ b/drivers/i2c/busses/i2c-cadence.c +@@ -353,8 +353,13 @@ static void cdns_i2c_mrecv(struct cdns_i2c *id) + ctrl_reg = cdns_i2c_readreg(CDNS_I2C_CR_OFFSET);

The +"wicked game" can be checked on line 700 of include/linux/cpumask.h. + +The original code in debug_cpumask_set_cpu() and cpumask_of_node() were +probably written by the original authors with CONFIG_CPUMASK_OFFSTACK=y +(i.e. dynamic allocation) in mind, checking if the cpumask was available +via a direct NULL check. + +When CONFIG_CPUMASK_OFFSTACK is not set, GCC gives the above warning +while compiling the kernel. + +Fix that by using cpumask_available(), which does the NULL check when +CONFIG_CPUMASK_OFFSTACK is set, otherwise returns true. Use it wherever +such checks are made. + +Conditional definitions of cpumask_available() can be found along with +the definition of cpumask_var_t. Check the cpumask.h reference mentioned +above. + +Fixes: c032ef60d1aa ("cpumask: convert node_to_cpumask_map[] to cpumask_var_t") +Fixes: de2d9445f162 ("x86: Unify node_to_cpumask_map handling between 32 and 64bit") +Signed-off-by: Siddh Raman Pant +Signed-off-by: Ingo Molnar +Link: https://lore.kernel.org/r/20220731160913.632092-1-code@siddh.me +Signed-off-by: Sasha Levin +--- + arch/x86/mm/numa.c | 4 ++-- + 1 file changed, 2 insertions(+), 2 deletions(-) + +diff --git a/arch/x86/mm/numa.c b/arch/x86/mm/numa.c +index fa150855647c..b4ff063a4371 100644 +--- a/arch/x86/mm/numa.c ++++ b/arch/x86/mm/numa.c +@@ -826,7 +826,7 @@ void debug_cpumask_set_cpu(int cpu, int node, bool enable) + return; + } + mask = node_to_cpumask_map[node]; +- if (!mask) { ++ if (!cpumask_available(mask)) { + pr_err("node_to_cpumask_map[%i] NULL\n", node); + dump_stack(); + return; +@@ -872,7 +872,7 @@ const struct cpumask *cpumask_of_node(int node) + dump_stack(); + return cpu_none_mask; + } +- if (node_to_cpumask_map[node] == NULL) { ++ if (!cpumask_available(node_to_cpumask_map[node])) { + printk(KERN_WARNING + "cpumask_of_node(%d): no node_to_cpumask_map!\n", + node); +-- +2.35.1 + diff --git a/queue-4.19/x86-pmem-fix-platform-device-leak-in-error-path.patch b/queue-4.19/x86-pmem-fix-platform-device-leak-in-error-path.patch new file mode 100644 index 00000000000..aff4be7cd14 --- /dev/null +++ b/queue-4.19/x86-pmem-fix-platform-device-leak-in-error-path.patch @@ -0,0 +1,41 @@ +From 0ea6630b87ba89b1a715f08298101e5801fdcaeb Mon Sep 17 00:00:00 2001 +From: Sasha Levin +Date: Mon, 20 Jun 2022 16:07:23 +0200 +Subject: x86/pmem: Fix platform-device leak in error path + +From: Johan Hovold + +[ Upstream commit 229e73d46994f15314f58b2d39bf952111d89193 ] + +Make sure to free the platform device in the unlikely event that +registration fails. + +Fixes: 7a67832c7e44 ("libnvdimm, e820: make CONFIG_X86_PMEM_LEGACY a tristate option") +Signed-off-by: Johan Hovold +Signed-off-by: Borislav Petkov +Link: https://lore.kernel.org/r/20220620140723.9810-1-johan@kernel.org +Signed-off-by: Sasha Levin +--- + arch/x86/kernel/pmem.c | 7 ++++++- + 1 file changed, 6 insertions(+), 1 deletion(-) + +diff --git a/arch/x86/kernel/pmem.c b/arch/x86/kernel/pmem.c +index 6b07faaa1579..23154d24b117 100644 +--- a/arch/x86/kernel/pmem.c ++++ b/arch/x86/kernel/pmem.c +@@ -27,6 +27,11 @@ static __init int register_e820_pmem(void) + * simply here to trigger the module to load on demand. + */ + pdev = platform_device_alloc("e820_pmem", -1); +- return platform_device_add(pdev); ++ ++ rc = platform_device_add(pdev); ++ if (rc) ++ platform_device_put(pdev); ++ ++ return rc; + } + device_initcall(register_e820_pmem); +-- +2.35.1 + -- 2.47.3
