1, this RomFS's codebase is Nuttx romfs, then it is compatible with
Linux RomFS and you can create such a file system using the tool genromfs.
2, there are two major changes against with the original Nuttx romfs:
1), it is memory-based: all contents of the fs are stored in the
memory in the very first stage of "mount".
2), this version of romfs is altered to be compatible with our new
version of VFS to take advantage of vnode cache and path cache.

This option turns on the -fstack-protector GCC feature. This
|
|
feature puts, at the beginning of functions, a canary value on
|
|
the stack just before the return address, and validates
|
|
the value just before actually returning. Stack based buffer
|
|
overflows (that need to overwrite this return address) now also
|
|
overwrite the canary, which gets detected and the attack is then
|
|
neutralized via a kernel panic.
|
|
|
|
This feature requires gcc version 4.2 or above, or a distribution
|
|
gcc with the feature backported. Older versions are automatically
|
|
detected and for those versions, this configuration option is
|
|
ignored. (and a warning is printed during bootup)
