[Bug 1741081] Re: zfs-import-cache.service fails on startup
IMHO this is completely backwards, see
https://github.com/zfsonlinux/zfs/pull/7259 for an upstream discussion
similar to this.
systemd service units are not the proper place to load modules - there
is {/lib,/etc}/modules-load.d/ which gets parsed by systemd-load-
modules.service early in the boot process, and ZoL even ships a
(disabled by default) snippet for /lib that supports. just flip that one
to enabled (admin can override via /etc) and you don't need to introduce
bogus services.

[Bug 1674838] Re: kernel BUG at /build/linux-7LGLH_/linux-4.10.0/include/linux/swapops.h:129
the only big mm changes pulled in from 4.11.x that I could find with a
quick look through the history are related to KSM, but those are missing
a later fixup (from 4.11.x as well):
d75450ff40df0199bf13dfb19f435519ff947138 which fixes ace71a19cec5 ("mm:
introduce page_vma_mapped_walk()")
ace71a19cec5 was first contained in Ubuntu-4.10.0-14.16, which AFAICT
fits nicely into the working/non-working kernels reported by various
users here?
there are also a few other commits by the same upstream author, which do
not explicitly contain any followup/fixes tags but touch similar code,
some of which were picked.
since I cannot reproduce the problem at hand, I cannot tell whether
including that fixup helps, but it might be worth a shot.

[Bug 1682368] [NEW] refcount underflow / kernel NULL dereference after attempting to add basic tc filter
Public bug reported:
== SRU Justification ==
Impact: adding a tc filter sometimes fails, potentially followed by
kernel hangs and kernel NULL pointer dereference
Fix: proposed upstream by Wolfgang Bumiller [1,2]
Regression Potential: Since nobody else noticed this issue in 4.11 >=
rc1 or Ubuntu 4.10 >= 15.17, and the fix only touches the broken code,
the regression potential should be minimal ;)

Commit 1045ba77a which was backported for #1674087 in
fc0cef7a8ec1e63ee3405f642983dd86e04ab6cc (first released with
Ubuntu-4.10.0-15.17) introduces the problematic code. Note that while
the traces below were generated using a custom patched kernel, the same
issue is reproducible using Ubuntu Zesty's 4.10.0-15.17 (and later)
kernels.
The full cover letter of the proposed fix by my colleague Wolfgang
Bumiller follows:
Commit 1045ba77a ("net sched actions: Add support for user cookies")
added code to net/sched/act_api.c's tcf_action_init_1 using the `tb`
nlattr array unconditionally, while it was otherwise used as well as
initialized only when `name == NULL`:
if (name == NULL) {
err = nla_parse_nested(tb, TCA_ACT_MAX, nla, NULL);
In the other case `nla` is instead passed over to ->init to be parsed
there (using a different set of TCA_ enum values, iow. TCA_ACT_COOKIE
then "clashes" with some other value). This lead to the following three
example commands resulting in errors (sometimes followed by more traces
and hangups some time later (although the hangups happened seconds or
sometimes minutes later, sometimes not at all - results differed between
different kernel versions (linux git-master vs ubuntu's mainline 4.11
rc6 vs. pve 4.10.5 (based off ubuntu's zesty kernel where the commit is
cherry-picked)...))):
# ip link add ve0 type veth peer name ve0b
# tc qdisc add dev ve0 handle : ingress
# tc filter add dev ve0 parent : prio 50 basic police rate 1000bps burst
1000b drop
The 3rd command would sometimes succeed, sometimes error with:
RTNETLINK answers: Invalid argument
We have an error talking to the kernel
and sometimes error with:
RTNETLINK answers: Cannot allocate memory
We have an error talking to the kernel
In the latter case I assume `cklen` became negative, which passes the
TC_COOKIE_MAX_SIZE check since it is signed but becomes unsigned later
in kmemdup() (see the crash dump below)
When the `tc filter add` command fails a backtrace shows up in dmesg,
added below.
I'm not sure why the TC_ACT_COOKIE code was added to tcf_action_init_1
where it is now. It makes me think that it's supposed to be available
universally, but the `name == NULL` check for how nla is used or passed
to ->init() shows that the there are various different TC_ACT_* enums in
use at this point, hence the 'RFC' part of the patches, I'm not that
familiar with the code yet.
Backtrace when running `tc filter add`:

[Bug 1636517] [NEW] zfs: importing zpool with vdev on zvol hangs kernel
Public bug reported:
if a zvol of an existing, already imported zpool is a vdev of another
zpool, a call to "zpool import" will everything zfs related. the stack
trace is as follows:
[] taskq_wait+0x74/0xe0 [spl]
[] taskq_destroy+0x4b/0x100 [spl]
[] vdev_open_children+0x12d/0x180 [zfs]
[] vdev_root_open+0x3c/0xc0 [zfs]
[] vdev_open+0xf5/0x4d0 [zfs]
[] spa_load+0x39e/0x1c60 [zfs]
[] spa_tryimport+0xad/0x450 [zfs]
[] zfs_ioc_pool_tryimport+0x64/0xa0 [zfs]
[] zfsdev_ioctl+0x44b/0x4e0 [zfs]
[] do_vfs_ioctl+0x29f/0x490
[] SyS_ioctl+0x79/0x90
[] entry_SYSCALL_64_fastpath+0x16/0x71
[] 0x
I traced this back to 193fb6a2c94fab8eb8ce70a5da4d21c7d4023bee (merged
in 4.4.0-6.21), which added a second parameter to lookup_bdev without
patching the zfs module (which needs to special case the vdev-on-zvol
case, and uses this exact method only in this special casing code path).
attached you can find the output of "zfs send -R" ing such a zvol
("brokenvol.raw"), running "zfs receive POOL/TARGET < FILE" followed by
"zpool import" should reproduce the hang.

[Bug 1636517] Re: zfs: importing zpool with vdev on zvol hangs kernel
attached patch with fix tested with 4.4.0-45.66 note that instead of hardcoding the patched variant of lookup_bdev, it might make sense to adapt the zfs automake files to autodetect and handle both one parameter and two parameter variants? that way, all three variations of building the zfs module would work: dkms source with either an Ubuntu or upstream kernel Ubuntu kernel with zfs module source in module/zfs/ ** Patch added: "zfs-fix-zpool-import-bug-with-nested-pools.patch" https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1636517/+attachment/4767015/+files/zfs-fix-zpool-import-bug-with-nested-pools.patch -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1636517 Title: zfs: importing zpool with vdev on zvol hangs kernel To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1636517/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

can confirm that the test packages correctly allow importing of such pools. thanks for the quick reaction! minor nitpick since you referenced me in the changelog, please either spell my last name "Grünbichler" (with 'ü'), or transcribed with 'ue', and not with an 'i' - thanks! :) -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1636517 Title: zfs: importing zpool with vdev on zvol hangs kernel To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1636517/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

[Bug 1566465] Re: [regression]: Failed to call clock_adjtime(): Invalid argument
This seems to be caused by the call to "timeval_inject_offset_valid()" introduced in kernel/time/ntp.c (in "ntp_validate_timex()") by 2ed8b5bac95a96e2334a6b9bcbe99eabaf83f931. timeval_inject_offset_valid only handles timevals with microseconds, but systemd-timesyncd uses the ADJ_NANO mode which stores nanosecond values in tv_usec. upstream 4.5 already has a fix to handle this situation by copying the tv content to a (temporary) timespec and validating that iff ADJ_NANO is used. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1566465 Title: [regression]: Failed to call clock_adjtime(): Invalid argument To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1566465/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
