Hi,
Version 1.8.2 has a reproducible segfault with "-E all-fragments"
(testing on Fedora 40). When compressing the install image, it
consistently hangs on a firmware file:
sudo dnf -y install erofs-utils
wget
https://dl.fedoraproject.org/pub/fedora/linux/releases/40/Everything/x86_64/os/images/install.img
sudo mount install.img /mnt
sudo mkfs.erofs -z zstd -E all-fragments erofs.img /mnt
If you isolate just that firmware directory instead of the whole
image, it will segfault:
mkfs.erofs -z zstd -E all-fragments erofs.img
/mnt/usr/lib/firmware/nvidia/ga102/gsp
It happens with all compressors I've tried, but adding "dedupe" works
around it. Is there any change I should test? Let me know if you
need additional information.
Thanks for the report, I will look into that.
I've submited a fix for this,
https://lore.kernel.org/r/[email protected]
The original one is a SquashFS xz image:
Compression xz
Dictionary size 131072
Filters selected: x86
Block size 131072
Inodes are compressed
Data is compressed
Fragments are compressed
..
so the results are:
618008576 install.img
621953024 install.erofs (mkfs.erofs -zlzma -C131072
-Eall-fragments,ztailpacking -T0)
Since EROFS doesn't support metadata compression for now,
the difference is just out of compressed metadata.
Thanks,
Gao Xiang
