usr.bin/man: allow man(1) to search translated manpages in pure $man_lang subdirectory (+)
Currently our man(1) utility search manages only in $lang_country.$charset, $lang.$charset and,
as failover, in en.$charset which is historical behavior.
But nowadays most of ported software uses only $lang subdirectories for translated manpages
instead of use full locale notation, for example, share/ja/man1, share/de/man1, share/ru/man1.
In such cases, our man(1) utility cannot find any translated manpages and silently fallback to english version.
Add $man_lang in search path allows man(1) search and use translated manpages under historical and modern path traditions

sctp: improve handling of SO_SETFIB socket option
Since SCTP keeps fibnum in the SCTP protocol control block,
the code can't just defer the processing to the IPv4 or IPv6
layer. Therefore it needs to be implemented in the the SCTP
layer and it needs to call the socket layer function.

sound examples: trigger dsp devices via syncgroup
Triggering is only needed if device is in mmap mode, and in mmap example
the device is triggered as part of syncgroup. For non-mmap mode,
triggering is not needed at all. Triggering mmap'ed device too early
would start the IPTR/OPTR counters and that would cause those pointers
to be out of sync, so let syncgroup do the triggering once the device is
fully configured and ready for capture and playback.

amdsmu: Use devclass name instead of module name
The diagnostics array contained expected modules to be loaded but the
checking logic checked for if a devclass of that name existed instead.
Have the diagnostics array contain the devclass instead as well as the
module to load for the hint string.
Furthermore, check tha the number of devices is greater than 0 so that
leftover devclasses from unloaded modules don't skip the hint.

riscv: Map the DTB when it is outside the kernel's 1GB region
When the kernel is started directly by SBI firmware, locore.S maps only
the 1GB region that contains the kernel, and initriscv() reads the DTB
through that mapping at the physical address passed in a1. If the
firmware put the DTB in another 1GB region, as QEMU does with more than
1GB of RAM, fake_preload_metadata() faults before the console is up and
the kernel hangs.
Also map the 1GB region that contains the DTB.
This fixes direct kernel booting without FreeBSD loader(8).

tcp: Preserve borrowed ICMPv6 error mbufs
The TCP-over-UDP ICMP callback receives ip6c_m as a borrowed chain owned
by icmp6_notify_error. It used m_pulldown() to obtain a contiguous UDP
header even though that API frees the complete chain when the requested
range is unavailable. The callback could then return without
propagating the lost ownership, leaving raw ICMP delivery to read and
free a stale head.
Validate that the complete UDP header was quoted, copy it through the
chain with m_copydata(), and temporarily advance the parser offset
instead of consuming bytes from the caller-owned packet.
A remote sender can reach the old path when TCP UDP tunneling is enabled
by quoting the configured local UDP source port in an ICMPv6 error and
including only four through seven UDP-header bytes.

net: Fix handling of sockaddrs in the SIOC{ADD,DEL}MULTI handlers
The SIOCADDMULTI and SIOCDELMULTI handlers add or delete a link-layer
multicast address from an interface's multicast filter list. The
link-layer address is passed using the ifr_addr field of the request
structure.
struct ifreq's ifr_addr field is a struct sockaddr, which is a fair bit
smaller than struct sockaddr_dl (though big enough to hold an ethernet
address). Existing callers set the sockaddr length to
sizeof(struct sockaddr_dl), which is too large, and causes OOB accesses
when if_findmulti() is used to compare the address with others, or when
if_addmulti() makes a copy.
Fix this without breaking compatibility: copy the user-supplied address
into a sockaddr_dl on the stack, and use the latter for the respective
operation.
Also validate the sockaddr_dl internal length fields, suggested by zlei.

jail: Fix a race in prison_deref()
If we're killing a jail which has some user refs pending, then we would
first drop our ref and then kill all processes in the prison. However,
it's possible for the prison to be freed before we finish that
operation, generally if the processes exit on their own before
prison_proc_iterate() returns.
Thus, defer the release of the prison refcount until after we've killed
all procs.

Since OSIOCAIFADDR_IN6 does not need to copy data back out, it can
simply use a struct in6_ifaliasreq on the stack.

icmp: Limit routing table updates to the FIB of the redirect
When we receive an ICMP redirect, rib_add_redirect() is used to apply
the redirect to all FIBs. This has been the case since support for
multiple FIBs was added. However, it seems rather dubious: the new
gateway might not be routable from all FIBs, and the validation done for
v4 redirects in icmp_verify_redirect_gateway() is only applied to the
FIB from which the redirect originated.
Modify the handler to apply the redirect only in the originating FIB.
