963fb2ad94 This commit brings things into sync with the advancements that
have been made in rack and adds a few fixes in BBR. This also
removes any possibility of incorrectly doing OOB data the stacks
do not support it. Should fix the skyzaller crashes seen in the
past. Still to fix is the BBR issue just reported this weekend
with the SYN and on sending a RST. Note that this version of
rack can now do pacing as well.

d3b6c96b7d Adjust the fb to have a way to ask the underlying stack
if it can support the PRUS option (OOB). And then have
the new function call that to validate and give the
correct error response if needed to the user (rack
and bbr do not support obsoleted OOB data).

ea69bf7f5d Set LG_VADDR to 48 on RISC-V.
The Sv48 PTE format is the largest currently defined address space for
RISC-V. It makes no sense to define a larger size and doing so (at
least for 64-bits) forces rtrees down a slow path.

9e02229580 Remove now-unused rt_ifp,rt_ifa,rt_gateway,rt_mtu rte fields.
After converting routing subsystem customers to use nexthop objects
 defined in r359823, some fields in struct rtentry became unused.

This commit removes rt_ifp, rt_ifa, rt_gateway and rt_mtu from struct rtentry
 along with the code initializing and updating these fields.

Cleanup of the remaining fields will be addressed by D24669.

This commit also changes the implementation of the RTM_CHANGE handling.
Old implementation tried to perform the whole operation under radix WLOCK,
 resulting in slow performance and hacks like using RTF_RNH_LOCKED flag.
New implementation looks up the route nexthop under radix RLOCK, creates new
 nexthop and tries to update rte nhop pointer. Only last part is done under
 WLOCK.
In the hypothetical scenarious where multiple rtsock clients
 repeatedly issue RTM_CHANGE requests for the same route, route may get
 updated between read and update operation. This is addressed by retrying
 the operation multiple (3) times before returning failure back to the
 caller.

8701adbeb0 [evdev] Add AT translated set1 scancodes for F-unlocked F1-12 keys.
"F lock" is a switch between two sets of scancodes for function keys F1-F12
found on some Logitech and Microsoft PS/2 keyboards [1]. When "F lock" is
pressed, then F1-F12 act as function keys and produce usual keyscans for
these keys. When "F lock" is depressed, F1-F12 produced the same keyscans
but prefixed with E0.
Some laptops use [2] E0-prefixed F1-F12 scancodes for non-standard keys.

0c1032665c Continuation of multi page mbuf redesign from r359919.
The following series of patches addresses three things:

Now that array of pages is embedded into mbuf, we no longer need
separate structure to pass around, so struct mbuf_ext_pgs is an
artifact of the first implementation. And struct mbuf_ext_pgs_data
is a crutch to accomodate the main idea r359919 with minimal churn.

Also, M_EXT of type EXT_PGS are just a synonym of M_NOMAP.

The namespace for the newfeature is somewhat inconsistent and
sometimes has a lengthy prefixes. In these patches we will
gradually bring the namespace to "m_epg" prefix for all mbuf
fields and most functions.

Step 1 of 4:

 o Anonymize mbuf_ext_pgs_data, embed in m_ext
 o Embed mbuf_ext_pgs
 o Start documenting all this entanglement

b43a935cae Resolve conflict between the fusefs(5) and mac_bsdextended(4) tests
mac_bsdextended(4), when enabled, causes ordinary operations to send many
more VOP_GETATTRs to file system. The fusefs tests expectations aren't
written with those in mind. Optionally expecting them would greatly
obfuscate the fusefs tests. Worse, certain fusefs functionality (like
attribute caching) would be impossible to test if the tests couldn't expect
an exact number of GETATTR operations.

This commit resolves that conflict by making two changes:

1. The fusefs tests will now check for mac_bsdextended, and skip if it's
   enabled.
2. The mac_bsdextended tests will now check whether the module is enabled, not
   merely loaded. If it's loaded but disabled, the tests will automatically
   enable it for the duration of the tests.

With these changes, a CI system can achieve best coverage by loading both
fusefs and mac_bsdextended at boot, and setting
security.mac.bsdextended.enabled=0

897e43124e Don't pass bogus keys down for NULL algorithms.
The changes in r359374 added various sanity checks in sessions and
requests created by crypto consumers in part to permit backend drivers
to make assumptions instead of duplicating checks for various edge
cases.  One of the new checks was to reject sessions which provide a
pointer to a key while claiming the key is zero bits long.

IPsec ESP tripped over this as it passes along whatever key is
provided for NULL, including a pointer to a zero-length key when an
empty string ("") is used with setkey(8).  One option would be to
teach the IPsec key layer to not allocate keys of zero length, but I
went with a simpler fix of just not passing any keys down and always
using a key length of zero for NULL algorithms.

c74959537c Use the HSM SBI extension to start APs
The addition of the HSM SBI extension to OpenSBI introduces a new
breaking change: secondary harts will remain parked in the firmware,
until they are brought up explicitly via sbi_hsm_hart_start(). Add
the call to do this, sending the secondary harts to mpentry.

If the HSM extension is not present, secondary harts are assumed to be
released by the firmware, as is the case for OpenSBI =< v0.6 and BBL.

In the case that the HSM call fails we exclude the CPU, notify the
user, and allow the system to proceed with booting.
