Hi all,
I have fuzzed EROFS for about a day and observed the following
issues due to corrupted compression images by my first fuzzer
(It seems ok for uncompressed images for now). Now it can survive
for 10+ minutes on my PC (Let me send out what I'm done and
I will dig it more deeply...)
All the fixes are trivial.
Note that those have dependency on EFSCORRUPTED, so for-next
is needed and I will manually backport them by hand due to
many cleanup patches...
Thanks,
Gao Xiang

staging: erofs: some compressed cluster should be submitted for
corrupted images
staging: erofs: cannot set EROFS_V_Z_INITED_BIT if fill_inode_lazy
fails
staging: erofs: add two missing erofs_workgroup_put for corrupted
images
staging: erofs: avoid loop in submit chains
staging: erofs: detect potential multiref due to corrupted images
staging: erofs: avoid endless loop of invalid lookback distance 0
