A review of v0.10.4-rc.4, and a look at the live network, found:
- Alertmanager listening on every interface: from any node its API took
silences, with no login. Bound to loopback on the monitoring host, and the
monitoring README now installs it that way; Prometheus beside it is its only
client, and one Alertmanager needs no cluster port.
- Login and signup unbounded in memory. Each attempt runs argon2 with 64 MiB,
and nothing limited how many ran at once; the per-address throttle kept one
entry per address ever tried. Hashing now takes one of a few slots and
waits for one otherwise. The throttle expires entries whose window has
passed when it fills, and if it is still full it refuses new addresses:
evicting live ones instead would let a flood of made-up addresses reset the
throttle on the address actually being guessed.
- Metric labels taken from the request. A refused request counted the model
name it asked for, so any key holder could mint a series per request.
Requests are counted under the catalog's name, or "unknown".
- Two in code written this week. A SQLite backup made its snapshot with the
default mode in the listable backup directory, a full copy of the store
readable while the backup ran; it is now made in a private directory, and
the unit sets UMask=0077. And archive links were checked by name only, so
"a -> ." then "a/a/b -> ../.." passed and a file written through them landed
above the install directory, as root. Archives now unpack through os.Root,
and a link may only point at a file beside it — which every llama.cpp
b10991 archive, CPU and CUDA, was checked to follow.
