First patch switches fuse_notify_inval_entry and fuse_notify_delete to allocate name buffers to the actual file name size and not FUSE_NAME_MAX anymore. Second patch increases the FUSE_NAME_MAX limit. Signed-off-by: Bernd Schubert <bschubert@xxxxxxx> --- Changes in v3: - New variable fc->name_max that is initialized to FUSE_NAME_LOW_MAX (1024B). The FUSE_NAME_MAX (PATH_MAX - 1) is only used when fuse server set max_pages > 1 in FUSE_INIT reply. - Link to v2: https://lore.kernel.org/r/20241213-fuse_name_max-limit-6-13-v2-0-39fec5253632@xxxxxxx Changes in v2: - Switch to PATH_MAX (Jingbo) - Add -1 to handle the terminating null - Link to v1: https://lore.kernel.org/r/20241212-fuse_name_max-limit-6-13-v1-0-92be52f01eca@xxxxxxx --- Bernd Schubert (2): fuse: Allocate only namelen buf memory in fuse_notify_ fuse: Increase FUSE_NAME_MAX to PATH_MAX fs/fuse/dev.c | 30 ++++++++++++++++-------------- fs/fuse/dir.c | 2 +- fs/fuse/fuse_i.h | 11 +++++++++-- fs/fuse/inode.c | 8 ++++++++ 4 files changed, 34 insertions(+), 17 deletions(-) --- base-commit: f92f4749861b06fed908d336b4dee1326003291b change-id: 20241212-fuse_name_max-limit-6-13-18582bd39dd4 Best regards, -- Bernd Schubert <bschubert@xxxxxxx>
