Push the KERNEL_LOCK() insidge pgsigio() and selwakeup().2020-02-14T14:32:44Zmpimpi@openbsd.org2020-02-14T14:32:44Zurn:sha1:112e0b7cd8c0810f5e6ec8c11d147cff217a606d
The 3 subsystems: signal, poll/select and kqueue can now be addressed
separatly.
Note that bpf(4) and audio(4) currently delay the wakeups to a separate
context in order to respect the KERNEL_LOCK() requirement. Sockets (UDP,
TCP) and pipes spin to grab the lock for the sames reasons.

Keep socket timeout intervals in nsecs and use them with tsleep_nsec(9).2020-01-15T13:17:35Zmpimpi@openbsd.org2020-01-15T13:17:35Zurn:sha1:1a273344ae32a61ecc379c236ac9b23f6623257d
Introduce and use TIMEVAL_TO_NSEC() to convert SO_RCVTIMEO/SO_SNDTIMEO
specified values into nanoseconds. As a side effect it is now possible
to specify a timeout larger that (USHRT_MAX / 100) seconds.
To keep code simple `so_linger' now represents a number of seconds with
0 meaning no timeout or 'infinity'.
Yes, the 0 -> INFSLP API change makes conversions complicated as many
timeout holders are still memset()'d.

Use the actual cluster size instead of fixed MCLBYTES for the2019-04-16T13:15:32Zyasuokayasuoka@openbsd.org2019-04-16T13:15:32Zurn:sha1:47e36d94cf73fe2760b8471620a58feafe448c87
condition in sb_compress(). Currently the actual cluster size might
be 9KB even if the mtu is 1500, in this case a lot of memory space had
been wasted, since sbcompress() doesn't compress because of previous
condition.

let sbcreatecontrol take a const void * instead of a caddr_t.2019-02-15T05:55:21Zdlgdlg@openbsd.org2019-02-15T05:55:21Zurn:sha1:edab645e68b5bf4d4b590ebc78778915ffb91f6c
this makes it easier to call since you don't have to cast to caddr_t
if it's a void *. this also changes a size argument from int to
size_t.

directly the functions and remove the defines.

mbufs and mbuf clusters are now backed by large pools. Because of this
we can relax the oversubscribe limit of socketbuffers a fair bit.
Instead of maxing out as sb_max * 1.125 or 2 * sb_hiwat the maximum is
increased to 8 * sb_hiwat -- which seems to be a good compromise between
memory waste and better socket buffer usage.

Do not unlock the KERNEL_LOCK() unconditionally in sounlock().2018-06-11T08:57:35Zmpimpi@openbsd.org2018-06-11T08:57:35Zurn:sha1:a8d8dd23955f49149264357db6db371bf1b8accf
Instead introduce two flags to deal with global lock recursion. This
is necessary until we get per-socket lock.
