ValueError: Invalid salt - cannot login after update to 0.22.1

rubo77 commented 7 years ago

After the latest update from 0.19 to 0.22 and then to 0.22.1 some users cannot login to our postgres database any more, some can.

This is the error in homeserver.log:

rubo77 commented 7 years ago

More info:

so the line that is broken is

    return bcrypt.hashpw(password.encode('utf8') + self.hs.config.password_pepper,
                         stored_hash.encode('utf8')) == stored_hash

which sounds like we may have changed the password_pepper in the HS config when doing the upgrade, but we didn't do anything

we have no pepper defined in our homeserver.yaml
looking at https://stackoverflow.com/a/36465345/6764493 it looks like you get that error if /anything/ goes wrong inside bcrypt so i will try upgrading the system bcrypt library and/or upgrading the python bcrypt package in my venv and hope that fixes it.

I upgraded libgcrypt20:amd64 (1.7.6-2, 1.7.6-2+deb9u1), but that didn't help

these are the versions installed:

libcrypt-openssl-random-perl 0.11-1+b3
libcrypt-random-seed-perl 0.03-1
libcrypt-random-source-perl 0.11-3
libcryptsetup4:amd64 2:1.7.3-4
python-bcrypt 3.1.2-1

rubo77 commented 7 years ago

I watched the homeserver.log for this error during the last two days and no more login 500 errors occur.

I can only create the error if i log n with one of the known two users.

it seems like only those two users on our server have this issue both created on the same computer at timestamp 1456866113 and 1491747697 but a user created in between at timestamp 1456870597 is working fine, so it cannot have anything to do with the version we used the time of user creation (all some time during 0.17.x or 0.18.x)

I'll try to analyse more of the difference between the userdata in the database, using this database structure visualisation to documentation

rubo77 commented 7 years ago

I think I found the error:

all users that cannot login have a password_hash that begins with

$2b$12$.....

all users that still can login start with this instead:

$2a$12$....

So you can fix the error with

psql -q --dbname="synapse" --command="update users set password_hash=replace(password_hash,'\$2b\$','\$2a\$') where password_hash like '\$2b%'"

rubo77 commented 7 years ago

At first I had not installed py-bcrypt. now I installed it with

pip install py-bcrypt

see:

$ pip freeze|grep bcrypt                                                                                              
bcrypt==3.1.2
py-bcrypt==0.4

maybe that would also have been a solution

richvdh commented 7 years ago

some things worth noting about this problem:

@rubo77 has bcrypt 3.1 installed in his virtualenv; synapse's python_dependencies.py requests py-bcrypt. These packages both provide implementations of the bcrypt module.
The users with problems have password hashes starting $2b$ . Those with hashes starting $2a$ do not cause a problem.
$2a$ and $2b$ correspond to different implementations of the bcrypt algorithm. In practice, they are the same, except for long (>72 chars?) passwords.
In my testing, bcrypt 3.1 generated $2b$ hashes, and supported decoding of both formats. py-bcrypt 0.4 only generated and supported $2a$ hashes.

The above explains why @rubo77 has $2b$ hashes in his users table. It does not explain why those users can't log in.

I suspect what has happened is that the virtualenv has got into a confused state and is now actually using the py-bcrypt implementation, rather than the bcrypt implementation, despite the fact that pip freeze reports otherwise.

rubo77 commented 7 years ago

so what would be the fix, if someone else would go into this problem? The manual sais:

pip2.7 install py-bcrypt

so maybe I should uninstall python-bcrypt, but that seems difficult:

apt-get remove python-bcrypt
...
The following packages will be REMOVED:
matrix-synapse python-bcrypt

richvdh commented 7 years ago

The main fix would be not to mix up the debian package and virtualenv. Decide which you want to use and stick with it.

The manual sais:

pip2.7 install py-bcrypt

It only says that under the Arch linux section, as a solution to a specific problem. Don't cut and paste random commands unless you know what you're doing.

maxidorius commented 7 years ago

This also happens under a standard package install without any virtualenv when trying to reset a password using hash_password.

My system: Linux Mint 18.1 (ubuntu 16.04 based) matrix-synapse 0.22.1-1
