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. Thus, we need to make sure to clean up all of the conn resources
which will also close sd. For all of the points prior to fetch_reopen(), we
continue to just close sd.

fetch_socks5_getenv will allocate memory for the host (or set it to NULL) in
all cases through the function; the caller is responsible for freeing it if
we end up allocating.
While I'm here, I've eliminated a label that just jumps to the next line...
This commit separates out port parsing and validation from grabbing the host
from the env var. The only related bit really is that we need to be more
specific with the delimiter in the IPv6 case.
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.

The default package use to be FreeBSD-runtime but it should only contain
binaries and libs enough to boot to single user and repair the system, it
is also very handy to have a package that can be tranform to a small mfsroot.
So create a new package named FreeBSD-utilities and make it the default one.
Also move a few binaries and lib into this package when it make sense.

were redirected to an HTTPS URL, and HTTPS proxying was enabled, we would

Mainly focus on files that use BSD 2-Clause license, however the tool I
was using mis-identified many licenses so this was mostly a manual - error
prone - task.
The Software Package Data Exchange (SPDX) group provides a specification
to make it easier for automated tools to detect and summarize well known
opensource licenses. We are gradually adopting the specification, noting
that the tags are considered only advisory and do not, in any way,
superceed or replace the license texts.
the host argument (e.g. "www.freebsd.org:443"), the service pointer,
which is supposed to point to the port or service part, instead points
to the separator, causing getaddrinfo() to fail.
Note that I have not been able to trigger this bug with fetch(1), nor
do I believe it is possible, as libfetch always parses the host:port
specification itself. I discovered it when I copied fetch_resolve()
into an unrelated project.

Rewrite fetch_resolve() so it handles bracketed literals correctly, and
remove similar code elsewhere to avoid passing unbracketed literals to
fetch_resolve(). Remove #ifdef INET6 so we still parse IP literals
correctly even if we do not have the ability to connect to them.
While there, fix an off-by-one error which caused HTTP 400 errors to be

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.

setlocale() so that static analyzers know that the string is NUL
terminated. This was causing a false positive in Coverity even
though the longest string returned by setlocale() is ENCODING_LEN
(31) and we are copying into a 64 byte buffer. This change is also
a bit of an optimization since we don't need the strncpy() feature
of padding the rest of the destination buffer with NUL characters.
