* sync: Go 1.21rc3, QUIC support added (#207) * sync: merge with upstream tag/go-1.21rc3 (#11) * fix: all tests pass * impl: UQUIC Transport * deps: bump up min Go version * new: uquic * fix: add QUICTransportParameter * deprecated: Go 1.19 no longer supported Go 1.19 will fail to build or pass the test once we bump up to the new version. * sync: crypto/tls: restrict RSA keys in certificates to <= 8192 bits (#209) * [release-branch.go1.21] crypto/tls: restrict RSA keys in certificates to <= 8192 bits Extremely large RSA keys in certificate chains can cause a client/server to expend significant CPU time verifying signatures. Limit this by restricting the size of RSA keys transmitted during handshakes to <= 8192 bits. Based on a survey of publicly trusted RSA keys, there are currently only three certificates in circulation with keys larger than this, and all three appear to be test certificates that are not actively deployed. It is possible there are larger keys in use in private PKIs, but we target the web PKI, so causing breakage here in the interests of increasing the default safety of users of crypto/tls seems reasonable. Thanks to Mateusz Poliwczak for reporting this issue. Fixes CVE-2023-29409 * build: [ci skip] boring not included * fix: typo [ci skip] * docs: replenish readme [ci skip] replace old build status badge with new ones, bump up required version noted in docs, update developer contact to reflect current status.
