2021-12-12New manual page providing a rudimentary description of BIO_new_NDEF(3).schwarze4-5/+127
The API surrounding this is so complicated and streaming is so rarely used in practice that describing this in more detail is not a priority right now. The documentation of the wrapper BIO_new_CMS(3) is also rather vague, and BIO_new_PKCS7() isn't described at all so far.

2021-12-11Merge two bugfixes in ASN1_STRING_TABLE_add(3) and ASN1_STRING_TABLE_get(3)schwarze3-36/+189
from the OpenSSL 1.1.1 branch, which is still under a free license, mostly this commit: commit d35c0ff30b31be9fd5dcf3d552a16feb8de464bc Author: Dr. Stephen Henson <steve@openssl.org> Date: Fri Oct 19 15:06:31 2012 +0000 fix ASN1_STRING_TABLE_add so it can override existing string table values This fixes a segfault in ASN1_STRING_TABLE_add(3), which tried to change a static const entry when called with an nid already in the default table, and it switches the precedence of the two tables in ASN1_STRING_TABLE_get(3). In addition, it changes behaviour in the following minor ways: * Ignore negative minsize and maxsize arguments, not just -1. * Ignore a zero mask and zero flags. It's unclear whether these additional changes make the API absolutely better, but we want compatibility with OpenSSL in these functions. Tweaks & OK tb@.

2021-12-09Add a section "NAMING CONVENTIONS".schwarze1-36/+285
There is no need to explain well-known acronyms that are widely used outside OpenSSL, too (like AES, ASN.1, CMS, ECDSA, PKCS...), but OpenSSL uses plenty of idiosyncratic naming elements that deserve to be explained (like d2i, ex, get0, ndef, sk, ...). Requested by jsing@; feedback and OK tb@.
2021-12-08lsearch(3): reimplement using lfind(3)cheloha1-32/+13
lsearch(3) is really just lfind(3) with an additional branch to append the key if lfind(3) fails. If we get rid of the underlying linear_base() function and move the search portion into lfind(3) and the key-copying portion into lsearch(3) we get smaller and simpler code. Misc. notes: - We do not need to keep the historical comment about errno. lsearch(3) is pure computation and does not set errno. That's really all you need to know. The specification reserves no errors, either. - We are using lfind(3) internally now, so it switches from PROTO_DEPRECATED to PROTO_NORMAL in hidden/search.h and needs DEF_WEAK in stdlib/lsearch.c. With advice from guenther@ on symbol housekeeping in libc. Thread: https://marc.info/?l=openbsd-tech&m=163885187632449&w=2 ok millert@

2021-12-07lsearch(3): append key to array with memmove(3) instead of memcpy(3)cheloha1-2/+7
If the key overlaps the end of the array, memcpy(3) mutates the key and copies a corrupted value into the end of the array. If we use memmove(3) instead we at least end up with a clean copy of the key at the end of the array. This is closer to the intended behavior. With input from millert@ and deraadt@.

2021-12-06In the next major bump, some BN macros will become functions.schwarze5-27/+11
In order to not forget it, already remove the statements that these APIs are currently implemented as macros: Not saying that doesn't make the documentation wrong.
2021-12-06Clean up a bunch of dead code in s_server.c and s_socket.ctb3-36/+21
jsg's analysis tool flagged a potential double free in do_server(). While this looks like a false positive, we can clean this code up a little: the host name passed to the callbacks isn't used by either sv_body() and www_body(), so it can be made local to do_accept() (an extra variable would not even be needed). Simplify the callbacks' signatures accordingly. Remove some commented out linger code that would never be used again anyway. ok inoguchi jsg
2021-12-05Simplify DH_check_params a bit.tb1-12/+4
It makes no sense to allocate an entire BN_CTX if we only use it to get a single BIGNUM, from which we subtract 1 to compare it to g. We can just use a plain BIGNUM and delete a bunch of lines. ok inoguchi jsing
