* libfetch: don't rely on ca_root_nss for certificate validationMichael Osipov2023-10-051-8/+0
| | | | | | | | | | | | | | | | | | | | | Before certctl(8), there was no system trust store, and libfetch relied on the CA certificate bundle from the ca_root_nss port to verify peers. We now have a system trust store and a reliable mechanism for manipulating it (to explicitly add, remove, or revoke certificates), but if ca_root_nss is installed, libfetch will still prefer that to the system trust store. With this change, unless explicitly overridden, libfetch will rely on OpenSSL to pick up the default system trust store.

* libfetch: Pass a zeroed digest to DigestCalcResponse.John Baldwin2023-01-241-2/+3
| | | | | | | | | | | | | GCC 12 warns that passing "" (a constant of char[1]) to a parameter of type char[33] could potentially overread. It is not clear from the context that c->qops can never be "auth-int" (and if it can't, then the "auth-int" handling in DigestCalcResponse is dead code that should be removed since this is the only place the function is called).

* fetch: support EAI_ADDRFAMILY error, correct two error messagesMike Karels2022-12-031-2/+5
| | | | | | | | | | | | | | | With the change to return EAI_ADDRFAMILY from getaddrinfo(), fetch would print "Unknown resolver error" for that error. Add that error and its string to libfetch's table, using an #ifdef just in case. Correct error strings for EAI_NODATA (although it is currently unused) and EAI_NONAME. Should maybe rework the code to use gai_strerror(3), but that doesn't map directly, and the current strings are shortened. Reviewed in https://reviews.freebsd.org/D37139 with related changes.

* libfetch: Use memcpy in place of an odd strncpy.John Baldwin2022-11-111-1/+1
| | | | | | | | | | | | | The length passed to strncpy is the length of the source string, not the destination buffer. This triggers a non-fatal warning in GCC 12. Hoewver, the code is also odd. It is really just a memcpy of the string without its nul terminator. For that use case, memcpy is clearer.

* Replace literal uses of /usr/local in C sources with _PATH_LOCALBASEStefan Eßer2020-10-271-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | Literal references to /usr/local exist in a large number of files in the FreeBSD base system. Many are in contributed software, in configuration files, or in the documentation, but 19 uses have been identified in C source files or headers outside the contrib and sys/contrib directories. This commit makes it possible to set _PATH_LOCALBASE in paths.h to use a different prefix for locally installed software. In order to avoid changes to openssh source files, LOCALBASE is passed to the build via Makefiles under src/secure. While _PATH_LOCALBASE could have been used here, there is precedent in the construction of the path used to a xauth program which depends on the LOCALBASE value passed on the compiler command line to select a non-default directory. This could be changed in a later commit to make the openssh build consistently use _PATH_LOCALBASE. It is considered out-of-scope for this commit.

| | | | | | | | | | | | | | In the successful case, sockshost is not freed prior to return. The failure case can now be hit after fetch_reopen(), which was not true before.

* fetch(3): Add SOCKS5 supportKyle Evans2020-02-153-11/+351
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This change adds SOCKS5 support to the library fetch(3) and updates the man page. Details: Within the fetch_connect() function, fetch(3) checks if the SOCKS5_PROXY environment variable is set. If so, it connects to this host rather than the end-host. It then initializes the SOCKS5 connection in accordance with RFC 1928 and returns the resulting conn_t (file descriptor) for usage by the regular FTP/HTTP handlers. Design Decision: This change defaults all DNS resolutions through the proxy by sending all IPs as hostnames. Going forward, another feature might be to create another environmental variable to toggle resolutions through the proxy or not.. One may set the SOCKS5_PROXY environment variable in any of the formats: SOCKS5_PROXY=proxy.example.com SOCKS5_PROXY=proxy.example.com:1080 SOCKS5_PROXY=192.0.2.0 SOCKS5_PROXY=198.51.100.0:1080 SOCKS5_PROXY=[2001:db8::1] SOCKS5_PROXY=[2001:db8::2]:1080 Then perform a request with fetch(1). (note by kevans) I've since been informed that Void Linux/xbps has a fork of libfetch that also implements SOCKS5. I may compare/contrast the two in the mid-to-near future.

Since 416 is an error code, any Content-Range header in the response would refer to the error message, not the requested document, so relying on the value of size when we know we got a 416 is wrong. Instead, just verify that offset == 0 and assume that we've reached the end of the document (if offset > 0, we did not request a range, and the server is screwing with us). Note that we cannot distinguish between reaching the end and going past it, but that is a flaw in the protocol, not in the code, so we just have to assume that the caller knows what it's doing. A smart caller would request an offset slightly before what it believes is the end and compare the result to what is already in the file.
