The HCL1 parser did not respect connect.sidecar_task.resources if the
connect.sidecar_service block was not set (an optimiztion that no longer
makes sense with connect gateways).
Fixes#10899
* driver: fix integer conversion error
The shared executor incorrectly parsed the user's group into int32 and
then cast to uint32 without bounds checking. This is harmless because
an out-of-bounds gid will throw an error later, but it triggers
security and code quality scans. Parse directly to uint32 so that we
get correct error handling.
* helper: fix integer conversion error
The autopilot flags helper incorrectly parses a uint64 to a uint which
is machine specific size. Although we don't have 32-bit builds, this
sets off security and code quality scaans. Parse to the machine sized
uint.
* driver: restrict bounds of port map
The plugin server doesn't constrain the maximum integer for port
maps. This could result in a user-visible misconfiguration, but it
also triggers security and code quality scans. Restrict the bounds
before casting to int32 and return an error.
* cpuset: restrict upper bounds of cpuset values
Our cpuset configuration expects values in the range of uint16 to
match the expectations set by the kernel, but we don't constrain the
values before downcasting. An underflow could lead to allocations
failing on the client rather than being caught earlier. This also make
security and code quality scanners happy.
* http: fix integer downcast for per_page parameter
The parser for the `per_page` query parameter downcasts to int32
without bounds checking. This could result in underflow and
nonsensical paging, but there's no server-side consequences for
this. Fixing this will silence some security and code quality scanners
though.
This PR sets the minimum Go version for the `api` submodule to Go 1.17.
It also upgrades
- gorilla/websocket 1.4.1 -> 1.4.2
- mitchelh/mapstructure 1.4.2 -> 1.4.3
- stretchr/testify 1.5.1 -> 1.7.0
Closes#11518#11602#11528
The volumewatcher that runs on the leader needs to make RPC calls
rather than writing to raft (as we do in the deploymentwatcher)
because the unpublish workflow needs to make RPC calls to the
clients. This requires that the volumewatcher has access to the
leader's ACL token.
But when leadership transitions, the new leader creates a new leader
ACL token. This ACL token needs to be passed into the volumewatcher
when we enable it, otherwise the volumewatcher can find itself with a
stale token.
The examples for `nomad volume create` and `nomad volume register` are
not setting `mount_flags` using an array of strings.
This fixes the issue by changing the example to be `mount_flags =
["noatime"]`.
This PR upgrades our CI images and fixes some affected tests.
- upgrade go-machine-image to premade latest ubuntu LTS (ubuntu-2004:202111-02)
- eliminate go-machine-recent-image (no longer necessary)
- manage GOPATH in GNUMakefile (see https://discuss.circleci.com/t/gopath-is-set-to-multiple-directories/7174)
- fix tcp dial error check (message seems to be OS specific)
- spot check values measured instead of specifically 'RSS' (rss no longer reported in cgroups v2)
- use safe MkdirTemp for generating tmpfiles
NOT applied: (too flakey)
- eliminate setting GOMAXPROCS=1 (build tools were also affected by this setting)
- upgrade resource type for all imanges to large (2C -> 4C)
github.com/kr/pty was moved to github.com/creack/pty
Swap this dependency so we can upgrade to the latest version
and no longer need a replace directive.
After swapping gzip handler to use the gorilla library, we
must account for a quirk in how zero/minimal length response
bodies are delivered.
The previous gzip handler was configured to compress all responses
regardless of size - even if the data was zero length or below the
network MTU. This behavior changed in [v1.1.0](c551b6c3b4 (diff-de723e6602cc2f16f7a9d85fd89d69954edc12a49134dab8901b10ee06d1879d))
which is why we could not upgrade.
The Nomad HTTP Client mutates the http.Response.Body object, making
a strong assumption that if the Content-Encoding header is set to "gzip",
the response will be readable via gzip decoder. This is no longer true
for the nytimes gzip handler, and is also not true for the gorilla gzip
handler.
It seems in practice this only makes a difference on the /v1/operator/license
endpoint which returns an empty response in OSS Nomad.
The fix here is to simply not wrap the response body reader if we
encounter an io.EOF while creating the gzip reader - indicating there
is no data to decode.
This has been pinned since the Go modules migration, because the
nytimes gzip handler was modified in version v1.1.0 in a way that
is no longer compatible.
Pretty sure it is this commit: c551b6c3b4
Instead use handler.CompressHandler from gorilla, which is a web toolkit we already
make use of for other things.
