* upstream: improve the error message for u2f enrollment errors bydjm@openbsd.org2020-01-261-1/+3
| | | | | | | | | | | | | making ssh-keygen be solely responsible for printing the error message and convertint some more common error responses from the middleware to a useful ssherr.h status code. more detail remains visible via -v of course. also remove indepedent copy of sk-api.h declarations in sk-usbhid.c and just include it. feedback & ok markus@ OpenBSD-Commit-ID: a4a8ffa870d9a3e0cfd76544bcdeef5c9fb1f1bb
* upstream: translate and return error codes; retry on bad PINdjm@openbsd.org2019-12-301-1/+3
| | | | | | | | | | | | Define some well-known error codes in the SK API and pass them back via ssh-sk-helper. Use the new "wrong PIN" error code to retry PIN prompting during ssh-keygen of resident keys. feedback and ok markus@ OpenBSD-Commit-ID: 9663c6a2bb7a0bc8deaccc6c30d9a2983b481620
* upstream: Improve strictness and control over RSA-SHA2 signaturedjm@openbsd.org2018-07-031-1/+3
| | | | | | | | | | | | | | | | | | | | | | | In ssh, when an agent fails to return a RSA-SHA2 signature when requested and falls back to RSA-SHA1 instead, retry the signature to ensure that the public key algorithm sent in the SSH_MSG_USERAUTH matches the one in the signature itself. In sshd, strictly enforce that the public key algorithm sent in the SSH_MSG_USERAUTH message matches what appears in the signature. Make the sshd_config PubkeyAcceptedKeyTypes and HostbasedAcceptedKeyTypes options control accepted signature algorithms (previously they selected supported key types). This allows these options to ban RSA-SHA1 in favour of RSA-SHA2. Add new signature algorithms "rsa-sha2-256-cert-v01@openssh.com" and "rsa-sha2-512-cert-v01@openssh.com" to force use of RSA-SHA2 signatures with certificate keys. feedback and ok markus@ OpenBSD-Commit-ID: c6e9f6d45eed8962ad502d315d7eaef32c419dde

| | | | | | | | | | | | | | | | | | | | | | refactor channels.c Move static state to a "struct ssh_channels" that is allocated at runtime and tracked as a member of struct ssh. Explicitly pass "struct ssh" to all channels functions. Replace use of the legacy packet APIs in channels.c. Rework sshd_config PermitOpen handling: previously the configuration parser would call directly into the channels layer. After the refactor this is not possible, as the channels structures are allocated at connection time and aren't available when the configuration is parsed. The server config parser now tracks PermitOpen itself and explicitly configures the channels code later. ok markus@ Upstream-ID: 11828f161656b965cc306576422613614bea2d8f

| | | | | | | Refuse RSA keys <1024 bits in length. Improve reporting for keys that do not meet this requirement. ok markus@ Upstream-ID: b385e2a7b13b1484792ee681daaf79e1e203df6c
* upstream committim@openbsd.org2015-09-161-2/+2
| | | | | | | | | | - Fix error message: passphrase needs to be at least 5 characters, not 4. - Remove unused function argument. - Remove two unnecessary variables. OK djm@ Upstream-ID: 13010c05bfa8b523da1c0dc19e81dd180662bc30

| | | | | | | | | | | | Revise hostkeys@openssh.com hostkey learning extension. The client will not ask the server to prove ownership of the private halves of any hitherto-unseen hostkeys it offers to the client. Allow UpdateHostKeys option to take an 'ask' argument to let the user manually review keys offered. ok markus@

[bufaux.c bufbn.c bufec.c buffer.c buffer.h sshbuf-getput-basic.c] [sshbuf-getput-crypto.c sshbuf-misc.c sshbuf.c sshbuf.h ssherr.c] [ssherr.h] New buffer API; the first installment of the conversion/replacement of OpenSSH's internals to make them usable as a standalone library. This includes a set of wrappers to make it compatible with the existing buffer API so replacement can occur incrementally.
