* libsysdecode: add Netlink attribute decoding infrastructureIshan Agrawal2026-07-241-2/+213
| | | | | | | | | | | | Introduce a generic Netlink attribute decoding framework based on attribute decoder tables. The framework supports decoding primitive attribute types as well as nested attributes and can be reused by different Generic Netlink families.

* libproc: link against libctf if MK_CTF != no instead of MK_CDDL != noEnji Cooper2026-07-161-1/+1
| | | | | | | | | | | | | | | Logic prior to this change would incorrectly try linking when MK_CDDL != no, instead of MK_CTF != no, which could result in the library and the tests being broken if/when MK_CTF == no and MK_CDDL != no (an uncommon, but possible combination with today's build knobs). This change updates the conditional to correctly track the value of MK_CTF, which in turn is properly toggled to no if/when MK_CDDL == no as it's a dependent build knob. This [niche] build bug has been present in FreeBSD since 2014. MFC after: 1 week

* libfetch: Add read bufferingDag-Erling Smørgrav2026-07-134-71/+118
| | | | | | | | | | | | | | | | | Previously, we would read FTP control connection messages and HTTP reponse headers one character at a time. Now, we read as much as will fit in our buffer and look for a newline. If there is data left over, it will be reused by the next fetch_getln() call. This also requires the addition of a fetch_bufread() which takes the buffer into account, otherwise the start of the HTTP response body will be stuck in the buffer after we read the last line of the header. This should noticeably improve HTTP performance, especially for small transfers. MFC after: 1 week Reviewed by: op Differential Revision: https://reviews.freebsd.org/D57907

* libllvmminimal: Fix building with LLVM < 21 on riscv64Jessica Clarke2026-07-061-1/+1
| | | | | | | | | | | | | | | | | | | | | | On most architectures we end up not needing ABIBreak.cpp as, although some of the sources here do reference EnableABIBreakingChecks (or, if assertions are disabled, DisableABIBreakingChecks) at a source level, we compile with -ffunction-sections and -fdata-sections, and link with --gc-sections, and it happens to be the case that all references can be GC'ed. However, prior to LLVM 21, the RISC-V backend did not apply -fdata-sections to .sdata, where references to these symbols end up, and for some files we're building with such references we end up not being able to GC .sdata due to the other unrelated data in it, meaning that we do in fact need to build ABIBreak.cpp. Whilst we could make this conditional on the architecture, it's a tiny file, and it's a bit fragile to rely on GC behaviour, so just include it unconditionally.

| | | | | | | | | | | | | | | | | When we switched from the BIND4 resolver to the BIND9 resolver, the sortlist parser was inadvertently disabled due to a missing #define, and nobody seemed to notice. The sorting code remained enabled in the resolver, but there was no way to set a sort order. Reimplement the sortlist parser, but correctly, and update the manual accordingly. The new parser accepts IPv4 and IPv6 addresses with or without a mask or prefix length, just like the old one, except IPv6 support was a bit wonky in the original code.

Sprinkle bounds checks and code comments all around. The sortlist code, which has been disabled for the past 20 years, will be dealt with in a separate commit.

| | | | | | | | | | | | | | | | | | | | | | | | Start the loop by finding the end of the option name, the name-value separator (if any), and the end of the option. Use those pointers to simplify matching the option name and parsing the option value, and validate option names and values more strictly. This means that: * We no longer accept trailing garbage in an option name or value. For instance, we would previously interpret “edns0123” as “edns0” and “timeout:3xyz” as “timeout:3”. This was actually quite lucky because we also failed to recognize the newline at the end of the option line as a whitespace character. * For options that take a numerical argument, we would previously accept negative values and treat non-numerical arguments as 0, while large numerical arguments would be capped to the option's maximum permitted value. Now, any failure to parse the argument, including overflow, results in the option being left unchanged.
