erofs-utils: lib: fix fd leak in erofs_metamgr_init()Commitd6d0b8a· authored bydeepakpathik· signed-off byhsiangkao(Gao Xiang, core EROFS maintainer)
In erofs_metamgr_init(), erofs_tmpfile() stores a file descriptor in m2gr->vf.fd. If the subsequent erofs_buffer_init() call fails, the function returns -ENOMEM without closing that fd — leaking it permanently. The caller erofs_metadata_init() only frees the m2gr struct at err_free, leaving no remaining reference to close the fd.
Fix: Mirror the success path's erofs_io_close(&m2gr->vf) call on the error path before returning.
if (!m2gr->bmgr) {
+ erofs_io_close(&m2gr->vf);
return -ENOMEM;
}
The Problemfsck.erofs runs all decompression on a single thread — leaving multi-core CPUs massively underutilized on production Android images, OTA pipelines, and container runtimes.
|
The Solution Wire the existing erofs_workqueue thread pool into the decompression path, enabling N pclusters to decompress concurrently across N worker threads with a new --jobs=N flag.
|
Key Technical Insightz_erofs_decompress() operates on a self-contained z_erofs_decompress_req — no shared mutable state. Output written via pwrite() to non-overlapping offsets. Zero inter-thread locks during decompression.
|
Expected Impact 3–4× extraction speedup on 4-core systems for CPU-bound images. Mirrors parallel decompression already present in the Linux kernel EROFS driver, closing the gap in userspace tools. |
