[Bug 1447282] Re: Does not use encrypted swap when using GPT partitioning + encrypted home directory (ecryptfs)

[Daniel López Azaña]

I renamed a partition other than swap partition from a gpt disk with
"parted name 9 " and in the next reboot I started to be asked to
enter a passprase for the swap partition. So this is another way to
reproduce this thread's issue that I think was not mentioned.

My version of ecryptfs-utils is 111-0ubuntu1.1 (Ubuntu 16.04.2 LTS).

GPT partition with encrypted /home.

Same error occurs if / gets a label or /home gets resized.

I encountered the same issue as well on Ubuntu 16.04.
In particular, this seems to occur only after I create a LUKS Encrypted 
partition by the disk util.

[Helge Jordan]

Bug doesn't seem to be fixed. I upgraded to ecryptfs-utils - 111-0ubuntu1 (see 
post by Launchpad Janitor (janitor) of 2016-07-14 - marking it as fixed).
However, the system keeps asking for a password for cryptswap1.
I rebuilt my swap as grosso did; however no success.

Grosso - can you open a new bug and include the following information:

  Attach /etc/fstab and /etc/crypttab

  Run the following commands and include their output:
  $ sudo blkid
  $ swapon -s
  $ printf "x\np\n" | sudo fdisk /dev/sda
  $ ls -l /run/systemd/generator/

[Bug 1447282] Re: Does not use encrypted swap when using GPT partitioning + encrypted home directory (ecryptfs)

[Tyler Hicks]

** Description changed:

- I'm still sorting out the details and eliminating variables, but as far
- as I can tell:
+ CVE Request: http://openwall.com/lists/oss-security/2016/07/13/2
+ 
+ 
+ I'm still sorting out the details and eliminating variables, but as far as I 
can tell:
  
  Steps to reproduce
  ===
  
  1) Install Ubuntu using GPT partitioning for the OS drive[*]
  
  2) Choose "require my password to login", and check "encrypt my home
  directory"
  
  Expected behavior
  ===
  
  No special user interaction should be required to initialized the
  crytposwap other than normally logging in
  
  Actual behavior
  
  
  Prior to lightdm coming up, you will be prompted to enter your
  passphrase to unlock the cryptoswap, similar to how you would be
  prompted to unlock the OS drive when using full disk encryption (see
  attached photo).
  
  When lightdm comes up, you have to enter your password/passphrase again
  to login.
  
  Work-arounds
  ===
  
  1) This only seems to happen when using GTP partitioning, not MBR... so
  use MBR if you can
  
  2) Even with GTP partitioning, booting with init=/sbin/upstart seems to
  reliably fix the problem, so it certainly seems systemd related
  
  Notes
  =
  
  * As far as I can tell, there isn't a way to force Ubiquity to create a
  GPT partition table when the OS drive is < 2TB, but it will
  automatically use GPT partitioning when the OS drive is >= 2TB. My
  particular test was done using the System76 imaging server, which by
  default uses GPT partitioning even when the OS drive is < 2TB.
  
- 
  SRU INFORMATION
  
  Regression potential:
  This is delicate as we need to fix existing installations with a post-install 
script. This needs to happen as defensively as possible, but errors in this can 
still potentially completely break your partition information. Apart from 
testing that in the above scenario the unencrypted swap partition is marked as 
"no-auto" and thus after a new boot you are actually using the cryptswap1 one, 
we also need to verify that it does not destroy working systems.
  
  Test case:
  (1) Install an EFI system with "encrypt my home directory" (You can do this 
in QEMU with -bios OVMF.fd); after booting the first time you will be asked to 
enter a passprase for the swap partition, just press enter. "sudo swapon -s" 
will say something like /dev/sda3, i. e. using unencrypted swap. After 
installing this update and rebooting, the bogus passphrase prompt on boot 
should be gone, and "sudo swapon -s" should say /dev/dm-0, i. e. using 
encrypted swap.
  
  In all these other cases the update should not do anything and booting 
continues to work:
  (2) In the above system, "sudo apt-get install --reinstall ecryptfs-utils" 
should not change partitions again, but say something like "is already marked 
as no-auto".
  (3) Install an EFI system without home dir encryption
  (4) Install an MBR system with home dir encryption
  (5) Install an MBR system without home dir encryption

[Bug 1447282] Re: Does not use encrypted swap when using GPT partitioning + encrypted home directory (ecryptfs)

[Jason Gerard DeRose]

@diwic - I agree, there have been problems in multiple places causing
this.

Yesterday I sorted out one of them. If you have swap on a GPT
partitioned NVMe or MMC drive, ecryptfs-setup-swap isn't correctly
marking the partition as non-auto-mounting, which leads the the user
erroneously being prompted to enter a passphrase to unlock the swap
partition.

I filed a bug about this and have a merge proposal ready for review:
https://bugs.launchpad.net/ecryptfs/+bug/1597154

This bug has been present in ecryptfs-utils since the original GPT auto
mounting issues was fixed, but not that long ago in 16.04 it didn't
result in being erroneously being prompted to enter a passphrase to
unlock the swap partition. Some some recent-ish behavior change
elsewhere has re-exposed this (I'm guessing a change in systemd).

Just in case it helps someone:

This symptom seems to have more than one root cause. For me, I had more
than one entry in /etc/crypttab, one being completely wrong. It was
probably a left-over from me switching hard drives a while ago, but then
the symptom only started to appear after a 14.04 -> 16.04 upgrade.

I'm experiencing this bug too, and my partitions are /dev/sda* type, so
the workaround in comment #74 has no effect. With the other issues in
boot and upgrade I have notice that my boot last until I stop or restart
any service

I think it's not related with de partition name type.

Re-tested today/yesterday with 16.04 LTS (official release), with
existing partitions deleted.

HP Stream 11 Pro G2 notebook (Braswell SoC, Celeron N3050), with 64GB
eMMC (SSD) storage.

Issue still occurs, with prompt (black box) on startup. No pauses (for
 at command line) doing update/upgrade, but also no updates
available (at present).

Corrected (per Comment #75, #76), with:

$ cat /etc/fstab
--
# swap was on /dev/mmcblk0p3 during installation
--

$ sudo sfdisk --part-attrs /dev/mmcblk0 3 "63"

(after reboot)
$ swapon -s

I meant sfdisk in the above message, whoops.

[Bug 1447282] Re: Does not use encrypted swap when using GPT partitioning + encrypted home directory (ecryptfs)

[Ben Whitten]

I believe the issue lies in the line;
drive="${phys_dev%[0-9]*}"

This matches fine for /dev/sda* type partitions but not /dev/nvme*n*p*
or /dev/mmcblk*p* resulting in a device that fdisk doesn't know about
and cant proceed to set the no-auto flag.

This is what I did to set the flag after installation and stop the prompts, use 
at your own risk double check your partitions and devices!!
Find out what partition your swap is on, look in /etc/fstab and it says where 
it was during installation, for me this was /dev/nvme0n1p7.
Set the no-auto flag on this partition with: fsdisk --part-attrs /dev/nvme0n1 7 
"63"
Reboot to no prompt.
Check with: swapon -s
I get /dev/dm-0

I just installed 16.04 and this issue still persists.

I have NVMe for some info.

[david6]

Re-tested today/yesterday with 16.04 LTS (xenial-desktop-amd64, daily-
build, 11-Apr), with existing partitions deleted, or SSD secure erased.

(a.) HP ProDesk 600 G2 SFF (Skylake, Core i5), with 256GB SSD (SATA 3
interface) storage.

No issue occurred.

(b.) HP Stream 11 Pro G2 notebook (Braswell SoC, Celeron N3050), with
64GB eMMC (SSD) storage.

Issue still occurs, with prompt (black box) on startup. Also has
multiple pauses (for  at command line) doing update/upgrade.

This could still be specific to 'NVMe' and 'eMMC' SSD media (which use
the simple /sda /sdb /sdc for path), as this appear to be a common
feature.

[Bug 1447282] Re: Does not use encrypted swap when using GPT partitioning + encrypted home directory (ecryptfs)

[david6]

Re-tested today with 16.04 LTS (xenial-desktop-amd64, daily-build,
07-Apr), and still occurring.

I have an HP Stream 11 Pro G2 notebook with 64GB eMMC (SSD) storage, and
existing partitions were deleted.

Minor issue: Notebook stalled with 'sda' (USB used for install) cache
/pass-thru error, after it prompted that install was complete. This
error may have previously occurred (earlier attempts, and during
install/load), but did not stop for me to read wording.

This did NOT pause (for  at command line) doing update/upgrade.
However, only a limited number of updates were available.

--

I think this specifically relates to 'NVMe' and 'eMMC' SSD media, as
this appear to be common feature for those reporting recent issues.

[Bug 1447282] Re: Does not use encrypted swap when using GPT partitioning + encrypted home directory (ecryptfs)

[lino]

Same behavior here with 16.04. On boot and on upgrades the systems ask
me for the password. If I use solution from #59 the system don't ask for
the password anymore but the system takes 2 minutes to boot.

Sorry, been busy with work.

Re-tested today, with 16.04 LTS beta2, and still occurring. Also
repeatedly stop for  at command line, doing update/upgrade.

I have an HP notebook with 64GB eMMC (SSD) storage, and existing
partitions were already deleted.

I had to move forward on this topic and went for a reinstallation using
full disk encryption so sadly I can't provide the requested information
anymore. Hopefully it will be reproducible within a VM by anyone.

[Bug 1447282] Re: Does not use encrypted swap when using GPT partitioning + encrypted home directory (ecryptfs)

[Martin Pitt]

@Dirk: In comment 61, what's the output of "blkid"? Is there any actual
partition with UUID=xxx that /etc/crypttab takes as source? I suppose
/dev/nvme0n1p3 is the physical swap partition on which the installer was
meant to put the encrypted partition. Does that appear in /etc/fstab?
Which /run/systemd/generator/*.swap files exist?

[Bug 1447282] Re: Does not use encrypted swap when using GPT partitioning + encrypted home directory (ecryptfs)

[Dirk Thomas]

I tried it again today with the Beta 2 of Xenial. These are the steps I
did:

* Downloaded Beta 2 of Xenial and created bootable USB stick
* Select: Try Ubuntu without installing
  * (I tried the option to install directly but that always hangs after 
selecting "Erase disk and install Ubuntu" and clicking "install")
* Check: Download updates during installation
* Select: Erase disk and install Ubuntu
* Check: Encrypt my home folder
* After installation finished and a restart it asks for: Please enter 
passphrase for disk cryptswap1 on none!
  * I hit enter without entering anything (same result when entering the 
password of the user)

The relevant content of the requested files:

* /etc/fstab:

/dev/mapper/cryptswap1 none swap sw 0 0

(This looks good using the device name instead of the UUID as
before.)

* /etc/crypttab

cryptswap1 UUID=xxx /dev/urandom swap,offset=1024,cipher=aes-xts-
plain64

But the swap is still not enabled. `swapon -s` reports the following:

/dev/nvme0n1p3 partition 33427212 0 -1

Any help to get this working is highly appreciated.

The solution describe here

enter-passphrase-for-disk-cryptswap1-on-none/) which uses the device

[Bug 1447282] Re: Does not use encrypted swap when using GPT partitioning + encrypted home directory (ecryptfs)

[Martin Pitt]

I just did an installation with today's xenial amd64 desktop image with
EFI, and things come out alright. I have an encrypted swap partition and
the unencrypted fake/stub swap partition is not touched.

Please be more specific how exactly you installed, and give me the
output of the following commands:

  sudo blkid
  swapon -s
  printf "x\np\n" | sudo fdisk /dev/sda
  ls -l /run/systemd/generator/

Thanks!

Re-tested with latest daily (07-Mar), and still occurring.

Also issue at command line, doing update, with halt for 'enter password'

Also, affects installation in GUI, when basically nothing indicates a
password (or just pressing Enter key) is required ans system waits and
waits until user opens console details and see what's happening. Quite
annoying for users unaware of this as package installation waits for
user interaction *without indicating so*.

[Bug 1447282] Re: Does not use encrypted swap when using GPT partitioning + encrypted home directory (ecryptfs)

[Christopher Armstrong]

I think there may be a regression on this issue: I just got this same
exact behavior (asking for a cryptswap passphrase during boot) on a
brand new Ubuntu 15.10 system76 laptop with updates applied. I've
contacted System76 support to let them know.

I'm also having some problems with LXC that may be related to this
problem, but I haven't figured that out yet.

[Bug 1447282] Re: Does not use encrypted swap when using GPT partitioning + encrypted home directory (ecryptfs)

[Ralph]

I didn't read the whole thing now, me it affected affected after I
activated the swap (not mapper) entry in fstab. I've done because I
thought, what the f***, I ran without swap all the time?

Then this entry appeared before lightdm and swapon --summary showed me 
/dev/sdXX. Disabling the classic swap line gave me a /dev/dm-0 device mapper 
reference... Jupiee problem solved.
I think cryptswap doesn't need a classic entry in fstab, but if there is one 
systemd gets confused, tries to access the cryptswap, asks for password, gets 
the wrong and activates classic swap... ouch

Best Regards

JuanYang, Martin, etc.: Your situation seems different, as you use LVM.
I don't know yet whether you also  use GPT, but as it's a sufficiently
different case, please file a new bug about this. Please include the
following:

 - output of sudo blkid
 - attach /etc/fstab and /etc/crypttab
 - run sudo journalctl -b  /tmp/journal.txt and attach /tmp/journal.txt.

Thanks!

[Bug 1447282] Re: Does not use encrypted swap when using GPT partitioning + encrypted home directory (ecryptfs)

[Martin]

Oh no, stay away from the Linux books. You'll just get cranky.
I am quite new myself; roughly 15 years now.

I fixed it by removing the swap partition everywhere ... swapoff -a;
cryptsetup remove everything that looks strange to you!

gut out:  /etc/fstab

rm everything with crypt here /dev/mapper/

I think it maybe down to me fixing the partition table  somewhat after
wrestling with UEFI.

Anyway, what's important is that when it comes to Linux, less is more!

@w-martin-h

Yeah, I get the same message as you after running that command.

Must admit, this bug is very frustrating for a newbie like me. I guess I
should just get a good Linux book and dive in so things like this are
more intuitive.

Until then I hope using MBR will work. I'll be back to let you guys
know.

[Bug 1447282] Re: Does not use encrypted swap when using GPT partitioning + encrypted home directory (ecryptfs)

[JunYang Pink]

Thanks for the help Jason but that didn't work either.

Upon reboot it still gave the 'please enter passphrase for disk ubuntu
--vg-swap_1(cryptswap1) on none!' message.

Since this was a fresh install I don't have much on my computer yet so I
wont mind redoing it. I want to try again using MBR instead of GPT.
However, just wondering what your thoughts are on MBR vs GPT as far as
security? From what I've read the main difference is that GPT is much
newer. Anything else I should be concerned about before the switch?

Thanks again for the help, I truly appreciate it.

[Bug 1447282] Re: Does not use encrypted swap when using GPT partitioning + encrypted home directory (ecryptfs)

[Jason Gerard DeRose]

@jun-yang - I haven't been able to reproduce your issue. I tried:

1) OEM mode install on an Intel-GPU system
2) OEM mode install on an Nvidia-GPU system

In all cases, encrypted home directory seemed to work fine for me and I
was never prompted for a passphrase to unlock the cryptoswap (note that
I had installed all the updates prior to running Prepare for shipping
to user).

Is your 15.04 install completely up-to-date? Also, now that the
ecryptfs-utils/libecryptfs1 update has landed in vivid-updates, you only
need do to this to make sure you have a fully up-to-date system:

sudo apt-get update
sudo apt-get -y dist-upgrade
sudo reboot

Please let us know if you're still having issues after running the above
3 commands.

[JunYang Pink]

One more thing.

After just now rebooting my system again I've come to realize that my
please enter passphase message is slightly different from the one
Jason pictured (IMG_7979_01.jpg) in post #1.

Jason's message says: 'please enter passphrase for disk
primary(cryptswap1) on none!'

Mines on the other had says:  'please enter passphrase for disk ubuntu
--vg-swap_1(cryptswap1) on none!'

I don't know if it matters much, just thought I should mention it.
Again, any help will be appreciated as I'd like to go about setting up
the rest of my environment.

[Bug 1447282] Re: Does not use encrypted swap when using GPT partitioning + encrypted home directory (ecryptfs)

[JunYang Pink]

Hey guys,

I'm still having trouble with this bug. Perhaps because I'm still fairly
new (~1 year) to linux.

I first noticed the please enter passphase error after the initial
install however, I didn't pay it any mind. Fast forward a few hours and
I decided to run the system updater because I did my install of 'vivid'
while offline. It was here when I ran into this cryptoswap1 error again
(I got the same screen as Jason in post #24).

Thats when I found this thread. Since then I've tried two things, first was:
$apt-get install --only-upgrade ecryptfs-utils

Every thing seemed to load fine however, when I tried the system update
it eventually did the same thing as above. Next after more digging I
tired : $bzr branch lp:ubuntu/vivid/ecryptfs-utils. This time after it
had finished I restarted my machine and was greeted with the same
please enter passphase error.  However, I was able to successfully run
the system updater with the cryptoswap1 error.

Any clue on what steps I should take to get rid of this error when
starting up my computer?

[Bug 1447282] Re: Does not use encrypted swap when using GPT partitioning + encrypted home directory (ecryptfs)

[Alistair Grant]

Just in case anyone else comes across this before the fix is released:

Booting without the normal splash screen, i.e. /etc/default/grub
contains:

GRUB_CMDLINE_LINUX_DEFAULT=

and not:

GRUB_CMDLINE_LINUX_DEFAULT=quiet splash

can result in the boot hanging waiting for input without a prompt.

[Bug 1447282] Re: Does not use encrypted swap when using GPT partitioning + encrypted home directory (ecryptfs)

[Jason Gerard DeRose]

@akgrant0710 - I haven't been able to reproduce your issues.

I started with an OEM mode install, installed all the updates currently
in Vivid proposed, created a user account with encrypted home directory,
confirmed that encrypted swap was working as expected.

Then I changed the /etc/default/grub line to:

GRUB_CMDLINE_LINUX_DEFAULT=

And then ran `sudo update-grub`.

But for me,  I wasn't prompted erroneously for the ecrypted swap
passphrase, and the swap was correctly initialized, confirmed with:

$ swapon --summary

When you tested, did you have all the updates from proposed installed?
The new ecryptfs-utils package hasn't yet hit Vivid updates.

[Bug 1447282] Re: Does not use encrypted swap when using GPT partitioning + encrypted home directory (ecryptfs)

[Steve Langasek]

Martin, you've marked bug #1449555 as a duplicate of this bug, but this
bug is assigned to ecryptfs-utils.  The problem described in bug
#1449555 does *not* require ecryptfs-utils to be installed in order to
reproduce.  All that's required is to configure a line in /etc/crypttab
for /dev/urandom encryption - it doesn't even have to be enabled in
/etc/fstab.

This is a bug in systemd's handling of /etc/crypttab lines with
keyfile=/dev/urandom, and has *nothing* to do with ecryptfs-utils setup
of partitions.  I'm marking this bug as verification-failed.

[Bug 1447282] Re: Does not use encrypted swap when using GPT partitioning + encrypted home directory (ecryptfs)

[Martin Pitt]

Steve, given that the original reporter here confirmed that the fix
works, I'm marking this back as v-done. Bug 1449555 has a description
which is exactly the same as here: where the user selects to encrypt
their home directory, they will get a password prompt during boot and at
other times on the command-line requesting a password for cryptswap1..
This is due to the insufficient ecryptfs-setup-swap script, which is the
bug here.

Can you please file a new bug about your specific setup? Thanks!

[Bug 1447282] Re: Does not use encrypted swap when using GPT partitioning + encrypted home directory (ecryptfs)

[Jason Gerard DeRose]

Okay, if you apply all the updates currently in proposed using update-
manger (when you have an encrypted home directory setup), update-manager
will hang while configuring udev.

The only way to tell that's it's prompting for your cryptoswap
passphrase (which gets ignored anyway) is to expand the update-manger
details (see attached screenshot).

So in total there are still some issues with what's currently sitting in
proposed. Whether or not this is enough of a problem to block these
SRUs, I don't know... on the one hand, I'm keen to see the ecryptfs-
utils SRU land as soon as possible. On the other hand, these updates
currently need some hand-holding by the user (when encrypted home
directory is being used anyway).

I suppose one work-around is to just land the ecryptfs-utils SRU first,
then wait on the systemd SRU for a few days to minimize the number of
users effecting by updating both at the same time. Actually, I'll test
that scenario now just to double check.

[Jason Gerard DeRose]

The ecryptfs-utils update itself seems fine. However, the systemd update
in proposed seems to have problems when encrypted home directory is
being used, whether or not you've installed the ecryptfs-utils update
first (and even rebooted) prior to installing the other packages in
proposed.

I need to experiment a bit more with this...

[Bug 1447282] Re: Does not use encrypted swap when using GPT partitioning + encrypted home directory (ecryptfs)

[Jason Gerard DeRose]

Some more details: I tested 3 scenarios, all starting with an OEM mode
install. The first 2 worked fine, the 3rd seems to have some issues:

1) Install all current updates in proposed from the OEM account, then
prepare for shipping to user, then create a user account with an
encrypted home directory. No issues.

2) Prepare for shipping to user, then create a user account with an
encrypted home directory, then install *only* ecryptfs-utils,
libecryptfs0 from proposed. No issues.

3) Prepare for shipping to user, then create a user account with an
encrypted home directory, then install *all* updates from proposed. The
systemd update is prompts for the encrypted swap passphrase twice and
results in a package error (an indicator pops up with the error),
although after a reboot things seem to probably be fine.

I ran scenario (3) from a terminal, still need to see what happens when
I run it from the update-manager. Also, if you don't enter your
passphrase (or at least press enter, the passphrase seems to be ignored
anyway), the prompt will hit a timeout and the update will fail. So my
biggest concern in running this from the update manager, will try that
now...

Okay, if you update ecryptfs-utils, libecryptfs0 first *and* reboot
prior to installing the other updates currently in proposed, then there
are no issues.

I'm removing the verification-needed tag as from the perspective of
this ecryptfs-utils SRU itself, things are all good in my book. But
folks should keep in mind the gotchas involved with the systemd SRU
combined with encrypted home directory.

Yes, I agree. My concern is that this bug here will cause the udev
prompt for pretty much any package update (from -proposed or
-security) that runs the udev package trigger. So we should get
ecryptfs in ASAP, and postpone the others.

ubiquity can also install updates during installation, so that at
least some new installs will get the correct partitions
right away.

Thanks for your extensive tests!

Martin,

I just built ecryptfs-utils with your updated patch, and it seem solid,
no issues found. FYI, I tested in OEM mode where the customer chooses
encrypted home directory during the first-run-user-config, as that's the
scenario that's most important for System76.

Thanks!

[Bug 1447282] Re: Does not use encrypted swap when using GPT partitioning + encrypted home directory (ecryptfs)

[Martin Pitt]

** Description changed:

  I'm still sorting out the details and eliminating variables, but as far
  as I can tell:
  
  Steps to reproduce
  ===
  
  1) Install Ubuntu using GPT partitioning for the OS drive[*]
  
  2) Choose require my password to login, and check encrypt my home
  directory
  
  Expected behavior
  ===
  
  No special user interaction should be required to initialized the
  crytposwap other than normally logging in
  
  Actual behavior
  
  
  Prior to lightdm coming up, you will be prompted to enter your
  passphrase to unlock the cryptoswap, similar to how you would be
  prompted to unlock the OS drive when using full disk encryption (see
  attached photo).
  
  When lightdm comes up, you have to enter your password/passphrase again
  to login.
  
  Work-arounds
  ===
  
  1) This only seems to happen when using GTP partitioning, not MBR... so
  use MBR if you can
  
  2) Even with GTP partitioning, booting with init=/sbin/upstart seems to
  reliably fix the problem, so it certainly seems systemd related
  
  Notes
  =
  
  * As far as I can tell, there isn't a way to force Ubiquity to create a
  GPT partition table when the OS drive is  2TB, but it will
  automatically use GPT partitioning when the OS drive is = 2TB. My
  particular test was done using the System76 imaging server, which by
  default uses GPT partitioning even when the OS drive is  2TB.
  
+ 
+ SRU INFORMATION
+ 
+ Regression potential:
+ This is delicate as we need to fix existing installations with a post-install 
script. This needs to happen as defensively as possible, but errors in this can 
still potentially completely break your partition information. Apart from 
testing that in the above scenario the unencrypted swap partition is marked as 
no-auto and thus after a new boot you are actually using the cryptswap1 one, 
we also need to verify that it does not destroy working systems.
+ 
+ Test case:
+ (1) Install an EFI system with encrypt my home directory (You can do this 
in QEMU with -bios OVMF.fd); after booting the first time you will be asked to 
enter a passprase for the swap partition, just press enter. sudo swapon -s 
will say something like /dev/sda3, i. e. using unencrypted swap. After 
installing this update and rebooting, the bogus passphrase prompt on boot 
should be gone, and sudo swapon -s should say /dev/dm-0, i. e. using 
encrypted swap.
+ 
+ In all these other cases the update should not do anything and booting 
continues to work:
+ (2) In the above system, sudo apt-get install --reinstall ecryptfs-utils 
should not change partitions again, but say something like is already marked 
as no-auto.
+ (3) Install an EFI system without home dir encryption
+ (4) Install an MBR system with home dir encryption
+ (5) Install an MBR system without home dir encryption

[Bug 1447282] Re: Does not use encrypted swap when using GPT partitioning + encrypted home directory (ecryptfs)

[Martin Pitt]

Two ideas how to fix that:

 * ecryptfs-setup-swap should change the partition type UUID to not be swap 
any more so that we don't try and auto-activate it. This is my preferred 
solution if it works.
 * ecryptfs-setup-swap creates an override .swap unit which disables the 
auto-mounting. But as we would again have to refer to real device names, we 
lose the entire point of keeping the underlying unencrypted swap partition, i. 
e. so that we can refer to it by UUID.

** Package changed: systemd (Ubuntu Vivid) = ecryptfs-utils (Ubuntu
Vivid)

[Bug 1447282] Re: Does not use encrypted swap when using GPT partitioning + encrypted home directory (ecryptfs)

[Martin Pitt]

So it is as I suspected:

 * ecryptfs-setup-swap creates cryptswap1 at 512KiB offset of the former real 
swap partition (vda3), and adds that to /etc/crypttab; as we need/want the 
UUID, we keep the original swap header
 * During boot, systemd-gpt-generator sees the apparent unencrypted swap 
partition on vda3 and creates a .swap unit for this. This doesn't happen on 
classic MBR partitions, as there are no partition type UUIDs and no 
auto-discovery
 * The real encrypted swap partition (cryptswap1) gets enabled later, and 
that fails with busy as the unencrypted partition is already active.

[Bug 1447282] Re: Does not use encrypted swap when using GPT partitioning + encrypted home directory (ecryptfs)

[Martin Pitt]

For w-series and upstream we need to fix this in ecryptfs-setup-swap
directly -- either mark the partition as such, or better yet, stop
having a swap partition in the first place. This has created an
inordinate amount of pain and breakage so far :-(

** Also affects: ecryptfs-utils
   Importance: Undecided
   Status: New

This is the debdiff I uploaded to the vivid-proposed review queue.
WARNING: the code will make your eyes pop out :-(

I tested this under various scenarios to make sure it doesn't destroy
anything unrelated, and it does fix this issue.

For the record, this horrible echo | fstab construction is apparently
the only thing (apart from dd) which can change GPT partition flags. I
talked to upstream util-linux, and Karel will work on adding support for
GPT to sfdisk, so that this will look less hideous.

[Jason Gerard DeRose]

Martin,

I just built ecryptfs-utils with your patch, and it fixed the problem!
I'll beat up on it more through the day, see if I come across any corner
cases where there are still issues.

And you're right... that's some seriously scary looking shell scripting
in there. But it works :D

Thanks!
