Since c67f3b8b78 the sockbuf mutexes belong to the containing socket,
and socket buffers just point to it. In 74a68313b5 macros that access
this mutex directly were added. Go over the core socket code and
eliminate code that reaches the mutex by dereferencing the sockbuf
compatibility pointer.
This change requires a KPI change, as some functions were given the
sockbuf pointer only without any hint if it is a receive or send buffer.
This change doesn't cover the whole kernel, many protocols still use
compatibility pointers internally. However, it allows operation of a
protocol that doesn't use them.

If we already had a pipe set in the actions struct we need to take care
to clear the flag if we're overwriting it with a queue.
This can happen if we've got Ethernet rules setting a dummynet pipe.
It does this indirectly, by adding the dummynet information to a pf_mtag
associated with the mbuf.

If we delay route-to/dup-to/reply-to through dummynet we are eventually
returned to pf_test(). At that point we no longer have the context for
the route-to destination. We'd just skip the pf_test() and continue
processing. This means that route-to did not work as expected.
Extend pf_mtag to carry the route-to destination so we can apply it when
we re-enter pf_test().

If packets are processed by a route-to/dup-to/reply-to rule (i.e. they
pass through pf_route(6)) dummynet was not applied to them.
This is because pf_route(6) passes packets directly to ifp->if_output(),
so the dummynet functions were never called.
Factor out the dummynet code and call dummynet prior to
ifp->if_output(). This has a secondary benefit of reducing some code
duplication between the IPv4 and IPv6 paths.

First paragraph refers to old past "we used to" and is no longer
important today. Second paragraph has just a wrong statement that
socket buffer is destroyed before pru_detach.
On success gnu libc sched_getaffinity() should return 0, unlike underlying

This makes it so we don't leak a consistent 64 bytes anymore,
makes the searches simpler and faster, removes /all allocations/
from the driver (quite trivially, since they were absolutely needless),

does pointer-width loads/stores so it's also mostly fine, except for

The zloop.sh script is primarily designed to randomly stress

Since the longer we run zloop.sh the more likely this is to occur

Extend the size of the local rx_buffer_size variable to account for
larger buffer sizes possible on 82580, i350 chips.
From i350 datasheet, 6.2.10 Initialization Control 4 (LAN Base Address
+ Offset 0x13):
When 4 ports are enabled maximum buffer size is 36 KB. When 2 ports are
enabled maximum buffer size is 72 KB. When only a single port is
enabled maximum buffer size is 144 KB.
and 8.3:
The overall available internal buffer size in the I350 for all ports is
144 KB for receive buffers and 80 KB for transmit Buffers. Disabled
ports memory can be shared between active ports and sharing can be
asymmetric. The default buffer size for each port is loaded from the
EEPROM on initialization.
From the reporter:
But for I350 when only 2 ports are used PBA size can be set as 72KB
(see datasheet RXPbsize or e1000_rxpbs_adjust_82580 function in
e1000_82575.c). In this case calculating the rx_buffer_size overflows
as 0x0048 << 10 = 73728 or 0x12000 pushed into u16. It is then set as
0x2000 or 8192.

The PermitRootLogin option "prohibit-password" was added as a synonym
for "without-password" in 2015. Then in 2017 these were swapped:
"prohibit-password" became the canonical option and "without-password"
became a deprecated synonym (in OpenSSH commit 071325f458).
The UsePAM description in sshd_config still mentioned
"without-password." Update it to match the new canonical option.

Even on Illumos it's only available in the 32-bit programming
environment, and, quoth enable_extended_FILE_stdio(3C):

where "well-behaved" means that it

And the stdio/flush.c implementation reads:
/*
* if this is not an internal extended FILE then check
* if _file is being changed from underneath us.
* It should not be because if
* it is then then we lose our ability to guard against
* silent data corruption.
*/

(void) fprintf(stderr,
"Application violated extended FILE safety mechanism.\n"
"Please read the man page for extendedFILE.\nAborting\n");
abort();
}
This appears to be an insane workaround for broken implementation with
exposed FILE internals and _file being an u8, both only on non-LP64;
it's shimmed out on all LP64 targets in Illumos,
and we shim it out as well: just get rid of it
This appears to've been originally fixed in illumos-gate

space for 32-bit Solaris processes", "1085341 32-bit stdio routines

and enable_extended_FILE_stdio(3C):
- unsigned char _file; /* UNIX System file descriptor */
+ unsigned char _magic; /* Old home of the file descriptor */
+ /* Only fileno(3C) can retrieve the
value now */
and
+/*
