* Plug a long standing leak in libtls CRL handlingtb2022-02-081-2/+1
| | | | | | | | | X509_STORE_add_crl() does not take ownership of the CRL, it bumps its refcount. So nulling out the CRL from the stack will leak it. Issue reported by KS Sreeram, thanks! ok jsing
* Provide our own signature padding defines.jsing2022-02-012-6/+38
| | | | | | | | Rather than leaking libcrypto defines through the tls_sign_cb and tls_signer_sign() interfaces, provide and use our own TLS_PADDING_* defines. ok inoguchi@ tb@
* Revise signer callback interface.jsing2022-02-012-83/+128
| | | | | | | | | | | | | | | | | | | | | | | | | | The current design of tls_sign_cb provides a pointer to a buffer where the signature needs to be copied, however it fails to provide a length which could result in buffer overwrites. Furthermore, tls_signer_sign() is designed such that it allocates and returns ownership to the caller. Revise tls_sign_cb so that the called function is expected to allocate a buffer, returning ownership of the buffer (along with its length) to the caller of the callback. This makes it far easier (and safer) to implement a tls_sign_cb callback, plus tls_signer_sign can be directly plugged in (with an appropriate cast). While here, rename and reorder some arguments - while we will normally sign a digest, there is no requirement for this to be the case hence use 'input' and 'input_len'. Move padding (an input) before the outputs and add some additional bounds/return value checks. This is technically an API/ABI break that would need a libtls major bump, however since nothing is using the signer interface (outside of regress), we'll ride the original minor bump. With input from tb@ ok inoguchi@ tb@

* Introduce a signer interface intented to make TLS privsep simplereric2022-01-257-5/+438
| | | | | | | | | | | | | | | | to implement. Add a tls_config_set_sign_cb() function that allows to register a callback for the signing operation on a tls_config. When used, the context installs fake pivate keys internally, and the callback receives the hash of the public key. Add a tls_signer_*() set of functions to manage tls_signer objects. A tls_signer is an opaque structure on which keys are added. It is used to compute signatures with private keys identified by their associated public key hash. Discussed with and ok jsing@ tb@
* Check function return value in libtlsinoguchi2022-01-191-9/+21
| | | | | | | | | | | | EVP_EncryptInit_ex, EVP_DecryptInit_ex and HMAC_Init_ex are possible to fail and return error. Error from these functions will be fatal for the callback, and I choose to return -1. SSL_CTX_set_tlsext_ticket_key_cb.3 explains the return value of callback. This also could fix Coverity CID 345319. ok jsing@ tb@

* Clarify tls_config_set_*_file() file I/O semanticskn2021-06-221-13/+11
| | | | | | | | | | | | | | | | | | | | | | | | tls_config_set_*_file(3) do not just set the file paths like tls_config_set_*_path(3) do, they do load the given file(s) into memory directly using tls_config_load_file(). This distinction is important because it means a later tls_connect(3) will not do any file I/O (at least wrt. those files), which is relevant when for example pleding without "[rwc]path" after loading files into memory and before doing tls_connect(3). The manual's current wording made me use the following due to above way of pledging a program: tls_load_file() tls_config_set_ca_mem() tls_unload_file() While in fact a single tls_config_set_ca_file() call does the same. tls_config.c r1.26 (Aug 2016) change the code but forgot to amend the manual as noted by tb, thanks.

* Use SSL_AD_INTERNAL_ERRORtb2021-06-141-2/+2

* Avoid sending a trailing dot in SNI as a clienttb2021-06-011-6/+19
| | | | | | | | | | | | | While an FQDN includes a trailing dot for the zero-length label of the root, SNI explicitly does not contain it. Contrary to other TLS implementations, our tlsext_sni_is_valid_hostname() rejects a trailing dot. The result is that LibreSSL TLS servers encountering an SNI with trailing dot abort the connection with an illegal_parameter alert. This fixes an issue reported by danj in nc(1) and by sthen in ftp(1). DNS cluebat from florian. ok jsing
