description |
bash -c 'ulimit -f 1024; yes | head -n2097152' >/path/on/filesystem/under/test
On ext4, this test case prints something along the lines of:
bash: line 1: 11274 Broken pipe yes
11275 File size limit exceeded(core dumped) | head -n2097152
On ZFS, this test case incorrectly exits zero with no output, demonstrating that ZFS does not respect RLIMIT_FSIZE.
I asked a friend to run this on Solaris 5.10 and FreeBSD 10.0-CURRENT, and on those systems this test case correctly generates SIGXFSZ; so it seems that this is a bug in the Linux port of ZFS.
(This was discovered while tracking down Launchpad test suite failures under LXD on ZFS. Launchpad uses RLIMIT_FSIZE in one place to guard against bugs that cause debdiff to generate arbitrarily large amounts of output and fill the disk.)

bash -c 'ulimit -f 1024; yes | head -n2097152' >/path/on/filesystem/under/test

bash: line 1: 11274 Broken pipe yes

== Fix ==
Upstream fix https://github.com/behlendorf/zfs/commit/230c03e59d3d13d9b60125f73cf3fff327b45c21
== Test case ==
With the fix:
bash -c 'ulimit -f 1024; yes | head -n2097152' >/path/on/filesystem/under/test
should report:
bash: line 1: 11274 Broken pipe yes
11275 File size limit exceeded(core dumped) | head -n2097152
== Regression Potential ==
Could break read/writes semantics to zfs
