b38d86a585 warnx: fix needless static
I noticed after the review that these shouldn't be static. Remove the
'static' from them, otherwise concurrent calls to warn* might see a
similar but to the original.

4e0771b2da warnx: Save errno across calls that might change it.
When warn() family of functions is being used after err_set_file() has
been set to, for example, /dev/null, errno is being clobbered,
rendering it unreliable after, for example, procstat_getpathname()
when it is supposed to emit a warning. Then the errno is changed to
Inappropriate ioctl for device, destroying the original value (via
calls to fprintf()functions).

3e7449a37b Only use ASAN when using the in-tree compiler
When building FreeBSD 11 on a FreeBSD 12 system with
CROSS_TOOLCHAIN=llvm10 we end up trying to link against the packaged
version of the sanitizer library.  This resulted in a requirement for
getentropy(3) which is not present in FreeBSD 11.

116bc58260 xhci: Handle the case when MSI-X BAR is the same as IO BAR.
PCIe allows for MSI-X BAR to be either dedicated, or MSI-X Table may
be co-located in some functional BAR.  In the later case xhci(4) is
unable to allocate active resource for the table because BAR is
already activated.

Handle it by checking for this special case, and not try to alloc
resource if MSI-X BAR is IO.

573456a931 libelf: add compression header support
GNU and Oracle libelf implementations added support for section
compression, intended to reduce the size of DWARF debug info (which
might be an order of magnitude larger than the code).

There are two compressed ELF section formats:

1. Old GNU - sections are renmaed to start with 'z'.  Section contains
   a magic number, uncompressed size, and compressed data.

2. Oracle and New GNU - compressed sections use the SHF_COMPRESSED flag.
   The compression header contains the compression type, uncompressed
   size, and uncompressed alignment.

The second style is preferred and this change implements only that one.

3862838921 cache: reduce memory waste in struct namecache
The previous scheme for calculating the total size was doing sizeof
on the struct and then adding the wanted space for the buffer.

nc_name is at offset 58 while sizeof(struct namecache) is 64.
With CACHE_PATH_CUTOFF of 39 bytes and 1 byte of padding we were
allocating 104 bytes for the entry and never accounting for the 6
byte padding, wasting that space.

c77b04884c Udpate calendar man-page to mention the search path added in r366962.
Calendar files in /usr/lcoal/share/calendar take precedence over files in
the base system. They can be provided by a port or package, but since such
a port has not been committed, yet, no specific port name is suggested.

In fact, multiple ports could exist (e.g. per locale) without conflicting
with each other.

34b38e1245 Add search of LOCALBASE/share/calendar for calendars supplied by a port.
Calendar files in LOCALBASE override similarily named ones in the base
system. This could easily be changed if the base system calendars should
have precedence, but it could lead to a violation of POLA since then the
port's files were ignored unless those in base have been deleted.

There was no definition of _PATH_LOCALBASE in paths.h, but verbatim uses
of /usr/local existed for _PATH_DEFPATH. Use _PATH_LOCALBASE here to ease
a consistent modification of this prefix.

8a82be5044 Handle CPL_RX_DATA on active TLS sockets.
In certain edge cases, the NIC might have only received a partial TLS
record which it needs to return to the driver.  For example, if the
local socket was closed while data was still in flight, a partial TLS
record might be pending when the connection is closed.  Receiving a
RST in the middle of a TLS record is another example.  When this
happens, the firmware returns the the partial TLS record as plain TCP
data via CPL_RX_DATA.  Handle these requests by returning an error to
OpenSSL (via so_error for KTLS or via an error TLS record header for
the older Chelsio OpenSSL interface).

c7520caa4f vfs: prevent avoidable evictions on mkdir of existing directories
mkdir -p /foo/bar/baz will mkdir each path component and ignore EEXIST.

The NOCACHE lookup will make the namecache unnecessarily evict the existing entry,
and then fallback to the fs lookup routine eventually leading namei to return an
error as the directory is already there.

For invocations like mkdir -p /usr/obj/usr/src/sys/GENERIC/modules this triggers
fallbacks to the slowpath for concurrently executing lookups.

a92c4bb62a Add support for IP over infiniband, IPoIB, to lagg(4). Currently only
the failover protocol is supported due to limitations in the IPoIB
architecture. Refer to the lagg(4) manual page for how to configure
and use this new feature. A new network interface type,
IFT_INFINIBANDLAG, has been added, similar to the existing
IFT_IEEE8023ADLAG .

ifconfig(8) has been updated to accept a new laggtype argument when
creating lagg(4) network interfaces. This new argument is used to
distinguish between ethernet and infiniband type of lagg(4) network
interface. The laggtype argument is optional and defaults to
ethernet. The lagg(4) command line syntax is backwards compatible.

f85aa85895 [hwpmc] Fix call chain capture for ARM64
Use ELR register value instead of LR for PMC_TRAPFRAME_TO_PC macro since
it's the former that indicates PC if the interrupted execution thread.

This fixes a bug where pmcstat lost the leaf function of the call chain
and started with the second function in the chain.

Although this change is an improvement over the previous logic there is still
posibility for incomplete data: if the leaf function does not have stack
variables and does not call any other functions compiler would not generate
a stack frame for it and the FP value would point to the caller's frame, so
instead of the actual "caller1 -> caller2 -> leaf" chain only
"caller1 -> leaf" would be captured.
