net80211: add a new field specifically for announcing specific ciphers
This dates way, way back with the original net80211 support w/ atheros chips.
The earliest chip (AR5210) had limitations supporting software encryption.
It only had the four WEP slots, and not any keycache entries. So when
trying to do CCMP/TKIP encryption would be enabled and the key slots
would have nothing useful in them, resulting in garbage encryption/decryption.
I changed this back in 2012 to disable supporting hardware WEP for AR5210
so if_ath(4) / net80211 crypto is all done in software and yes,
I could do CCMP/TKIP on AR5210 in software.
Fast-forward to newer-ish hardware - the Qualcomm 11ac hardware.
Those also don't support pass-through keycache slots! Well, the hardware
does at that layer, but then there's a whole offload data path encap/decap
layer that's turning the frames from raw wifi into ethernet frames (for
"dumb" AP behaviours) or "wifi direct" frames (ie, "windows".)
This hides a bunch of header frame contents required for doing the software
encryption / decryption path.
But then if you enable the raw transmit/receive frame format it ALSO
bypasses the hardware encryption/decryption engine!
So for those NICs:
* If you want to do encryption, you can only use the firmware supported
ciphers w/ wifi direct or ethernet;
* If you want to use software encrypt/decrypt, you MUST disable all encryption
and instead use 100% software encryption.
The wpa_supplicant bsd driver code has a specific comment about this and
flips on supporting WEP/TKIP/CCMP, which is understandable but it doesn't
fix the ACTUAL intention of all of this stuff.
So:
* create a new field, ic_sw_cryptocaps
* populate it with the default supported set of ciphers for net80211
(right now wep, tkip, ccmp)
* Communicate the combination of both ic_sw_cryptocaps and ic_cryptocaps
to wpa_supplicant via the relevant devcap ioctl.
* Update manpage.
I'll follow this up with a driver_bsd.c change in wpa_supplicant to
trust this again, and then start adding the other cipher support there.

https://stackoverflow.com/questions/78183545/does-compiling-imagick-with-openmp-enabled-in-freebsd-13-2-cause-sched-yield
If `__kmp_register_library_startup()` detects that another instance of

called. which uses `kmpc_alloc()` to allocate memory. This function
calls `__kmp_entry_thread()` to access the thread-local memory pool,
which is a bad idea during initialization. This macro internally calls
`__kmp_get_global_thread_id_reg()` which sets the bootstrap lock at the
beginning (before calling `__kmp_register_library_startup()`).
The fix is to use `KMP_INTERNAL_MALLOC()`/`KMP_INTERNAL_FREE()` instead
of `kmpc_malloc()`/`kmpc_free()`. `KMP_INTERNAL_MALLOC` and
`KMP_INTERNAL_FREE` do not use any bootstrap locks. They just translate

pf: always mark states as unlinked before detaching them
Users have reported crashes in pf_test_state_udp() where at least one state key
is NULL.
That suggests that pf_detach_state() ran concurrently with pf_test_state_udp().
pf_test_state_udp() holds the state lock (aka the id lock), but
pf_detach_state() does not.
The intent is that detached states are not returned by STATE_LOOKUP/
pf_find_state(), as the state's timeout is set to PFTM_UNLINKED and thus
pf_find_state() does not find the state.
There are other paths to pf_detach_state() (outside of pf_unlink_state())
though, where we did not set the timeout to PFTM_UNLINKED. Fix those, and assert
that the timeout is set correctly when we enter pf_detach_state().
There is only one functional change here - we don't allow SIOCSVH (or
netlink request) to change sc->sc_version. I'm convinced that allowing
such a change doesn't brings any practical value, but creates enless
minefields in front of both developers and end users (sysadmins). If
you want to switch from VRRP to CARP or vice versa, you'd need to recreate
the VHID.
Oh, one tiny funtional change: carp_ioctl_set() won't modify any fields
if it returns EINVAL. Previously you could provide valid advbase with
invalid advskew - that used to modify advbase and return EINVAL.
All other changes is a sweep around not ever using CARP fields when
we are in VRRP mode and vice versa. Also adding assertions on sc_version
where necessary.
Do not send VRRP vars in CARP mode via NetLink and vice versa. However
in compat ioctl SIOCGVH for VRRP mode the CARP fields would be zeroes.
This allows to declare softc as union and thus prevent any future logic
deterioration wrt to mixing VRRP and CARP.
- Separate HMAC preparation (CARP specific) from tagging.
- In unicast mode (CARP specific) don't put tag at all.
- Don't put pointer to software context into the tag. Putting just vhid,
an integer value, is a safer design.
Allow carp(4) to use the VRRPv3 protocol (RFC 5798). We can distinguish carp and
VRRP based on the protocol version number (carp is 2, VRRPv3 is 3), and support
both from the carp(4) code.

busdma: better handling of small segment bouncing
Typically, when a DMA transaction requires bouncing, we will break up
the request into segments that are, at maximum, page-sized.
However, in the atypical case of a driver whose maximum segment size is
smaller than PAGE_SIZE, we end up inefficiently assigning each segment
its own bounce page. For example, the dwmmc driver has a maximum segment
size of 2048 (PAGE_SIZE / 2); a 4-page transfer ends up requiring 8
bounce pages in the current scheme.
We should attempt to batch segments into bounce pages more efficiently.
This is achieved by pushing all considerations of the maximum segment
size into the new _bus_dmamap_addsegs() function, which wraps
_bus_dmamap_addseg(). Thus we allocate the minimal number of bounce
pages required to complete the entire transfer, while still performing
the transfer with smaller-sized transactions.
For most drivers with a segment size >= PAGE_SIZE, this will have no
impact. For drivers like dwmmc mentioned above, this improves the memory
and performance efficiency when bouncing a large transfer.

git-arc: Add list mode support for the update command
This can be particularly useful to do bulk-updates of multiple commits
using the same message, e.g.
git arc update -lm "Move function xyz to libfoo" main..myfeature
Similar to the list mode for the create command, git arc will list all
the candidate revisions with a single prompt. Once that is confirmed,
all the revisions are updated without showing the diffs or pausing
further prompts.
