42 hours	Improve error handling of psp(4) driver.	Alexander Bluhm
	The driver for the AMD platform security processor did use a bunch of EINVAL error codes. It is better to propagate the error up from the subsystem or use more specific values. Rename the variable "ret" to "error" to make clear where we deal with an actual errno(2). Document where and why the error code is ignored. OK hshoexer@

2 days	use ifq_deq_set_oactive if we're in an if_deq_begin "transaction"	David Gwynne
	reported by and fix tested by afresh@
2 days	provide ifq_deq_set_oactive.	David Gwynne
	ifq_deq_set_oactive is a variation on ifq_set_oactive that can be called inside an if_deq_begin "transaction". afresh@ found de(4) was calling ifq_set_oactive while holding the ifq mutex via ifq_deq_begin, which led to a panic because ifq_set_oactive also tries to take the ifq mutex. ifq_deq_set_oactive assumes the caller is already holding the mutex. de(4) is confusing, so it seemed simpler to add a small tweak to ifqs than try and do major surgery on such a hairy driver. tested by afresh@
2 days	use a tailq for the global list of bpf_if structs.	David Gwynne
	this replaces a hand rolled list that's been here since 1.1. ok claudio@ kn@ tb@

	dlg concurs
3 days	fix tcpdump on pfsync interfaces.	David Gwynne
	after the last rewrite i was showing bpf ip packets, not the pfsync payload like the PFSYNC DLT expected. this also lets bpf see packets being processed by pfsync input handling, so if you want to see only what's being sent you'll need to filter by direction. reported by Marc Boisis
3 days	i was missing a .Dv in front of a macro	David Gwynne

4 days	Cast atomic_load_int(9) to signed int when loading `securelevel'.	Vitaliy Makkoveev
	The return value of atomic_load_int(9) is unsigned so needs a cast, otherwise securelevel=-1 gets misrepresented. From Paul Fertser.

4 days	bump the "mru" up to MAXMCLBYTES.	David Gwynne
	there's no reason to limit tun/tap to small packets. ok claudio@

	ok patrick@
5 days	make sure bpfsdetach is holding a bpf_d ref when invalidating stuff.	David Gwynne
	when bpfsdetach is called by an interface being destroyed, it iterates over the bpf descriptors using the interface and calls vdevgone and klist_invalidate against them. however, i'm not sure the reference the interface holds against the bpf_d is accounted for properly, so vdevgone might drop it to 0 and free it, which makes the klist_invalidate a use after free. avoid this by taking a bpf_d ref before calling vdevgone and klist_invalidate so the memory can't be freed out from under the feet of bpfsdetach. Reported-by: syzbot+b3927f8ad162452a2f39@syzkaller.appspotmail.com i wasn't able to reproduce whatever syzkaller did. it's possible this is a double free, but we'll wait and see if it pops up again. ok mpi@
5 days	ec_lib: zap a useless comment	Theo Buehler

5 days	describe the endianness of tun_hdr	David Gwynne

5 days	Minor simplifications in ec_cmp()	Theo Buehler

5 days	minor grammar/macro fixes;	Jason McIntyre

5 days	Rewrite EC_GROUP_cmp()	Theo Buehler
	Use better variable names (cf. https://jmilne.org/math/tips.html#4) and avoid the weird style of assigning to r (what does r stand for anyway?) and short circuiting subsequent tests using if (r \|\| ...). Also, do not reuse the variables for order and cofactor that were previously used for the curve coefficients. ok jsing
5 days	try documenting tun_hdr	David Gwynne

5 days	make a first pass at documenting the network offload support.	David Gwynne
	the ioctls are here, the offload header is next.
5 days	provide network offloads between the kernel and userland again	David Gwynne
	userland can request that network packets that are read from or written to the device special file get prepended with a "tun_hdr" struct. this struct contains bits which say what offloads are requested for the packet, including things like ip/tcp/udp/icmp checksums, tcp segmentation offloads, or ethernet vlan tags. userland can write a packet with any of these offloads requested into the kernel at any time, but has to request which ones it's able to handle coming from the kernel. enabling the tun_hdr struct and which offloads userland can handle is done with a new TUNSCAP ioctl. this is based on the virtio_net_hdr in linux, which jan@ actually implemented and had working with vmd. however, claudio@ and i strongly opposed to what feels like a layer violation by pulling virtio structures into the tun driver, and then trying to emulate virtio/linux semantics in our network stack, and playing catch up when the "upstream" projects decide to change the shape or meaning of these bits. tun_hdr is specific to the openbsd network stack and it's semantics, which simplifies our kernel implementation. jan has been pretty gracious about the extra work on the vmd side of things. tested by and ok jan@ ok claudio@ sthen@ backed this out cos of confusion with the ioctl numbers i picked to controlling this feature. i've picked new numbers that don't conflict this time.
5 days	Add qccpucp(4), a driver for the CPUSS Control Processor (CPUCP) mailbox	Tobias Heider
	controller. It is used as doorbell for the arm-scmi perf protocol and a prerequisite for cpu frequency management on X Elite chips. ok patrick@
6 days	Do not call layout_fix_panes if wp is NULL (that is, a popup).	Nicholas Marriott

6 days	Simplify signature of ec_wNAF_mul()	Theo Buehler
	The only caller passes in num = 1 and is itself called in a path that ensures that the multiplier of the generator is != NULL. Consequently we don't need to deal with an array of points and an array of scalars so rename them accordingly. In addition, the change implies that numblocks and num_scalar are now always 1, so inline this information and take a first step towards disentangling this gordian knot. ok jsing
6 days	Provide a SHA-256 assembly implementation for amd64 using SHA-NI.	Joel Sing
	This provides a SHA-256 assembly implementation for amd64, which uses the Intel SHA Extensions (aka SHA New Instructions or SHA-NI). This provides a 3-5x performance gain on some Intel CPUs and many AMD CPUs. ok tb@
6 days	Remove sha512-x86_64.pl.	Joel Sing
	Now that we have replacement SHA-256 and SHA-512 assembly implementations for amd64, sha512-x86_64.pl can go the way of the dodo.
6 days	Provide a replacement assembly implementation for SHA-512 on amd64.	Joel Sing
	Replace the perlasm generated SHA-512 assembly with a more readable version and the same C wrapper introduced for SHA-256. As for SHA-256, on a modern CPU the performance is largely the same. ok tb@
6 days	Adjust deep logic in cursig() to handle sig_stop specially.	Claudio Jeker
	If any other signal is pending the stop signal should be deferred. Now cursig() uses ffs() to select the signal and so higher numbered signals like SIGUSR1 would be ignored when going to sleep. So handle default stop signals specially in the deep case, stash them and only use them if no other signal is pending. Fix for signal-stress regress (problem reported by anton@) With and OK mpi@
6 days	Add CPU capability detection for the Intel SHA extensions (aka SHA-NI).	Joel Sing
	This also provides a crypto_cpu_caps_amd64 variable that can be checked for CRYPTO_CPU_CAPS_AMD64_SHA. ok tb@
6 days	Remove unreachable check for orphaned process groups in cursig.	Claudio Jeker
	setsigctx() now does this check and clears sig_stop in that case and instead set sig_ignore. So the check in cursig that is based on sig_stop can never be true. OK mpi@
6 days	Specify size for K256 symbol.	Joel Sing
	Missing sizes spotted by guenther@
6 days	Merge ec_kmeth into ec_key	Theo Buehler

6 days	Shuffle the global default_ec_key_meth down a few lines	Theo Buehler

6 days	Move the default EC_KEY_METHOD to the end of the file	Theo Buehler

6 days	Do not dereference `pve' after releasing `pv_mtx'.	Martin Pieuchot
	Prevent a race where anything can happen on `pve' resultint in an incorrect locking of a given pmap. Found the hardway by sthen@. ok jsg@, miod@, kettenis@, jca@
6 days	Use a better curve and a better hash for the ECDSA_do_sign() example	Theo Buehler
	(Many examples in this directory are really bad. This is no exception.)
7 days	wait for ice(4) software interrupt to occur when flushing queue interrupts	Stefan Sperling
	This codes runs under IPL_NET. Interrupt processing would get delayed until the ioctl handler was done which is probably not what the device is expecting.
