knav_pool_create is an exported function. In the event of a call before knav_queue_probe, we encounter a NULL pointer dereference in the following line. Hence return -EPROBE_DEFER to the caller till the kdev pointer is non-NULL. Signed-off-by:

Commit b6a1d093 ("PM / Domains: Extend generic power domain debugfs") now creates a debugfs directory for each genpd based on the name of the genpd. Currently no name is given to the genpd created by ti_sci_pm_domains driver so because of this we see a NULL pointer dereferences when it is accessed on boot when the debugfs entry creation is attempted. Give the genpd a name before registering it to avoid this. Fixes: 52835d59 ("soc: ti: Add ti_sci_pm_domains driver") Signed-off-by:

The latest change of compat_sys_sigpending in commit 8f13621a ("sigpending(): move compat to native") has broken it in two ways. First, it tries to write 4 bytes more than userspace expects: sizeof(old_sigset_t) == sizeof(long) == 8 instead of sizeof(compat_old_sigset_t) == sizeof(u32) == 4. Second, on big endian architectures these bytes are being written in the wrong order. This bug was found by strace test suite. Reported-by:

ext4_xattr_inode_read() currently reads each block sequentially while waiting for io operation to complete before moving on to the next block. This prevents request merging in block layer. Add a ext4_bread_batch() function that starts reads for all blocks then optionally waits for them to complete. A similar logic is used in ext4_find_entry(), so update that code to use the new function. Signed-off-by:

When an xattr block has a single reference, block is updated inplace and it is reinserted to the cache. Later, a cache lookup is performed to see whether an existing block has the same contents. This cache lookup will most of the time return the just inserted entry so deduplication is not achieved. Running the following test script will produce two xattr blocks which can be observed in "File ACL: " line of debugfs output: mke2fs -b 1024 -I 128 -F -O extent /dev/sdb 1G mount /dev/sdb /mnt/sdb touch /mnt/sdb/{x,y} setfattr -n user.1 -v aaa /mnt/sdb/x setfattr -n user.2 -v bbb /mnt/sdb/x setfattr -n user.1 -v aaa /mnt/sdb/y setfattr -n user.2 -v bbb /mnt/sdb/y debugfs -R 'stat x' /dev/sdb | cat debugfs -R 'stat y' /dev/sdb | cat This patch defers the reinsertion to the cache so that we can locate other blocks with the same contents.

After commit 62d1034f53e3 ("fortify: use WARN instead of BUG for now"), we get a warning about possible stack overflow from a memcpy that was not strictly bounded to the size of the local variable: inlined from 'ext4_mb_seq_groups_show' at fs/ext4/mballoc.c:2322:2: include/linux/string.h:309:9: error: '__builtin_memcpy': writing between 161 and 1116 bytes into a region of size 160 overflows the destination [-Werror=stringop-overflow=] We actually had a bug here that would have been found by the warning, but it was already fixed last year in commit 30a9d7af ("ext4: fix stack memory corruption with 64k block size"). This replaces the fixed-length structure on the stack with a variable-length structure, using the correct upper bound that tells the compiler that everything is really fine here. I also change the loop count to check for the same upper bound for consistency, but the existing code is already correct here. Note that while clang won't allow certain kinds of variable-length arrays in structures, this particular instance is fine, as the array is at the end of the structure, and the size is strictly bounded.

The dir_nlink feature has been enabled by default for new ext4 filesystems since e2fsprogs-1.41 in 2008, and was automatically enabled by the kernel for older ext4 filesystems since the dir_nlink feature was added with ext4 in kernel 2.6.28+ when the subdirectory count exceeded EXT4_LINK_MAX-1. Automatically adding the file system features such as dir_nlink is generally frowned upon, since it could cause the file system to not be mountable on older kernel, thus preventing the administrator from rolling back to an older kernel if necessary. In this case, the administrator might also want to disable the feature because glibc's fts_read() function does not correctly optimize directory traversal for directories that use st_nlinks field of 1 to indicate that the number of links in the directory are not tracked by the file system, and could fail to traverse the full directory hierarchy. Fortunately, in the past ten years very few users have complained about incomplete file system traversal by glibc's fts_read(). This commit also changes ext4_inc_count() to allow i_nlinks to reach the full EXT4_LINK_MAX links on the parent directory (including "." and "..") before changing i_links_count to be 1.

This fixes a problem where the system gets stuck in a loop unable to wakeup via power button in s2idle. The problem happens because: - press power button: - system emits 0xc0 (power press), event ignored - system emits 0xc1 (power release), event processed, emited as KEY_POWER - set wakeup_mode to true - system goes to s2idle - press power button - system emits 0xc0 (power press), wakeup_mode is true, system wakes - system emits 0xc1 (power release), event processed, emited as KEY_POWER - system goes to s2idle again To avoid this situation, process the presses (which matches what intel-hid does too).

Add a ranges; line to the tscadc node. This creates a 1:1 mapping between the addresses used by tscadc and those in its child nodes (adc, tsc). Without such a mapping, the reg = ... lines in the tsc and adc nodes do not create a resource. Probing the fsl-imx25-tcq and fsl-imx25-tsadc drivers will then fail since there's no IORESOURCE_MEM.
