Since _inode_canonicalize() now resolves all "." and ".." segments in the common VFS layer before inode search, the relpath passed to each filesystem will never contain ".." segments. Remove the now-dead ".." handling code from individual filesystem layers and the inode search internals. Files modified (redundant ".." path resolution removed): - fs/hostfs/hostfs.c: remove depth-tracking escape check in hostfs_mkpath(), simplify to direct path concatenation. - fs/rpmsgfs/rpmsgfs.c: same as hostfs, remove depth-tracking in rpmsgfs_mkpath(). - fs/smartfs/smartfs_utils.c: remove "." and ".." segment checks in smartfs_finddirentry(), de-indent the remaining search logic. - fs/inode/fs_inodesearch.c: remove _inode_isdotdot() function, simplify _compute_path_depth() to only count forward segments, remove dead else-if branch in _inode_search(). Files NOT modified (and why): - fs/littlefs/littlefs/lfs.c: third-party upstream library (git submodule), must not be modified locally. - fs/fatfs/fatfs/source/ff.c: third-party upstream library. - fs/lwext4/lwext4/src/ext4*.c: third-party upstream library. - fs/cromfs/fs_cromfs.c: handles "." and ".." as directory entries (structural, not path resolution), so its code stays. - fs/vfs/fs_symlink.c: constructs relative paths containing ".." (writes, not parses relpath). Signed-off-by: yukangzhi <yukangzhi@xiaomi.com> |

Apache NuttX is a real-time operating system (RTOS) with an emphasis on standards compliance and small footprint. Scalable from 8-bit to 64-bit microcontroller environments, the primary governing standards in NuttX are POSIX and ANSI standards. Additional standard APIs from Unix and other common RTOSs (such as VxWorks) are adopted for functionality not available under these standards, or for functionality that is not appropriate for deeply-embedded environments (such as fork()).
For brevity, many parts of the documentation will refer to Apache NuttX as simply NuttX.
Getting Started
First time on NuttX? Read the Getting Started guide! If you don't have a board available, NuttX has its own simulator that you can run on terminal.
Documentation
You can find the current NuttX documentation on the Documentation Page.
Alternatively, you can build the documentation yourself by following the Documentation Build Instructions.
The old NuttX documentation is still available in the Apache wiki.
Supported Boards
NuttX supports a wide variety of platforms. See the full list on the Supported Platforms page.
Contributing
If you wish to contribute to the NuttX project, read the Contributing guidelines for information on Git usage, coding standard, workflow and the NuttX principles.
