[components][dfs_v2]: Fix dfs_devfs_open memory leak

2025-01-09T11:07:56Z

feat: devfs: handling unit size in POSIX RW request

2024-11-14T03:56:07Z

POSIX.1 says: > read() attempts to read up to count bytes from file descriptor fd > into the buffer starting at buf. On the other hand, for rt_device_read, the `@size` is defined as the number of unit (block size for blk device, otherwise one byte). Changes: - Transferred unit size from POSIX R/W(in bytes) to rt_device_R/W during request of file R/W operations. Signed-off-by: Shell

fixup: dfs_v2: Correct device mode permissions in devfs

2024-09-15T17:29:43Z

The mode permissions for character, block, and pipe devices were previously set to 0777, which is overly permissive and not in line with standard practice. This change reduces the permissions to 0666, restricting execute permissions while still allowing read/write access. Changes: - Adjusted permissions for character/block/pipe devices from 0777 to 0666. Signed-off-by: Shell

[dfsv2] fixup out-of-memory access (#8973)

2024-05-21T11:45:08Z

This change addresses a potential out-of-memory access issue in the devfs filesystem component. The issue arises when the `rt_malloc` function allocates memory for a path string without accounting for the null terminator, leading to undefined behavior. As the manual documented: > DESCRIPTION > The strlen() function calculates the length of the string pointed to > by s, excluding the terminating null byte ('\0'). To fix this, the memory allocation size was increased by one byte to ensure space for the null terminator. This prevents potential out-of-memory access and ensures proper string termination.
