| * regmap: Fix possible double-free in regcache_rbtree_exit()Yang Yingliang2021-11-02
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | commit 55e6d8037805b3400096d621091dfbf713f97e83 upstream. In regcache_rbtree_insert_to_block(), when 'present' realloc failed, the 'blk' which is supposed to assign to 'rbnode->block' will be freed, so 'rbnode->block' points a freed memory, in the error handling path of regcache_rbtree_init(), 'rbnode->block' will be freed again in regcache_rbtree_exit(), KASAN will report double-free as follows: BUG: KASAN: double-free or invalid-free in kfree+0xce/0x390 Call Trace: slab_free_freelist_hook+0x10d/0x240 kfree+0xce/0x390 regcache_rbtree_exit+0x15d/0x1a0 regcache_rbtree_init+0x224/0x2c0 regcache_init+0x88d/0x1310 __regmap_init+0x3151/0x4a80 __devm_regmap_init+0x7d/0x100 madera_spi_probe+0x10f/0x333 [madera_spi] spi_probe+0x183/0x210 really_probe+0x285/0xc30 To fix this, moving up the assignment of rbnode->block to immediately after the reallocation has succeeded so that the data structure stays valid even if the second reallocation fails.

| * regmap: debugfs: check count when read regmap filePeng Fan2020-07-31
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | commit 74edd08a4fbf51d65fd8f4c7d8289cd0f392bd91 upstream. When executing the following command, we met kernel dump. dmesg -c > /dev/null; cd /sys; for i in `ls /sys/kernel/debug/regmap/* -d`; do echo "Checking regmap in $i"; cat $i/registers; done && grep -ri "0x02d0" *; It is because the count value is too big, and kmalloc fails. So add an upper bound check to allow max size `PAGE_SIZE << (MAX_ORDER - 1)`.

| * regmap: dev_get_regmap_match(): fix string comparisonMarc Kleine-Budde2020-07-31
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | [ Upstream commit e84861fec32dee8a2e62bbaa52cded6b05a2a456 ] This function is used by dev_get_regmap() to retrieve a regmap for the specified device. If the device has more than one regmap, the name parameter can be used to specify one. The code here uses a pointer comparison to check for equal strings. This however will probably always fail, as the regmap->name is allocated via kstrdup_const() from the regmap's config->name. Fix this by using strcmp() instead.

| * regmap: fix bulk writes on paged registersSrinivas Kandagatla2019-08-04
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | [ Upstream commit db057679de3e9e6a03c1bcd5aee09b0d25fd9f5b ] On buses like SlimBus and SoundWire which does not support gather_writes yet in regmap, A bulk write on paged register would be silently ignored after programming page. This is because local variable 'ret' value in regmap_raw_write_impl() gets reset to 0 once page register is written successfully and the code below checks for 'ret' value to be -ENOTSUPP before linearising the write buffer to send to bus->write(). Fix this by resetting the 'ret' value to -ENOTSUPP in cases where gather_writes() is not supported or single register write is not possible.

We're supposed to be checking that "val_len" is not too large but instead we check if it is smaller than the max. The only function affected would be regmap_i2c_smbus_i2c_write() in drivers/base/regmap/regmap-i2c.c. Strangely that function has its own limit check which returns an error if (count >= I2C_SMBUS_BLOCK_MAX) so it doesn't look like it has ever been able to do anything except return an error.

One can use dd command to dump a subrange within the address space. However one needs to know the string length of each line which is derived from max address, the character length of each register entry and the format. Provide simple means to dump a range by allowing user to specify the start address and the count of registers. When the data is read convert the dump address to a starting position in the file. Similarly if the file offset goes beyond the dump range return 0 to indicate that the data is already dumped. Also provide means to write to a register address.

| * debugfs: Pass bool pointer to debugfs_create_bool()Viresh Kumar2015-10-04
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Its a bit odd that debugfs_create_bool() takes 'u32 *' as an argument, when all it needs is a boolean pointer. It would be better to update this API to make it accept 'bool *' instead, as that will make it more consistent and often more convenient. Over that bool takes just a byte. That required updates to all user sites as well, in the same commit updating the API. regmap core was also using debugfs_{read|write}_file_bool(), directly and variable types were updated for that to be bool as well.

That happens anytime a regmap read/write call needs to access another regmap. This is because, for performance reason, lockdep groups all locks initialized by the same mutex_init() in the same lock class. Therefore all regmap mutexes are in the same lock class, leading to lockdep "nested locking" warnings if a regmap accesses another regmap. In general, it is impossible to establish in advance the hierarchy of regmaps, so we make sure that each regmap init call initializes its own static lock_class_key. This is done by wrapping all regmap_init calls into macros. This also allows us to give meaningful names to the lock_class_key. For example, in rt5677 case, we have in /proc/lockdep_chains: irq_context: 0 [ffffffc0018d2198] &dev->mutex [ffffffc0018d2198] &dev->mutex [ffffffc001bd7f60] rt5677:5104:(&rt5677_regmap)->_lock [ffffffc001bd7f58] rt5677:5096:(&rt5677_regmap_physical)->_lock [ffffffc001b95448] &(&base->lock)->rlock The above would have resulted in a lockdep recursive warning previously. This is not the case anymore as the lockdep validator now clearly identifies the 2 regmaps as separate.
