cxgbe/tom: return rx credits promptly if the socket buffer's low water
mark cannot be reached because the window advertised to the peer isn't
wide enough. While here, tweak the normal credit return too.
Pass MODULES_EXTRA to the modules build. While I'm here, also always
pass WITHOUT_MODULES down. There's no need to make this conditional.
Properly quote EXTRA_MODULES and WITHOUT_MODULES to ensure that they
are passed down properly when there's more than one.
Merge latest dts files (commit c8c1b3a77934768c7f7a4a9c10140c8bec529059)
from the git tree.
File names with commas in them cause issues for freebsd-update. We
don't actually use these files at the moment, so eliminate them until
we actually do. In the mean time, freebsd-update will be updated
to eliminate the issues.
The GNU Amlogic DTS files have some errors (e.g. bad register
address, bad IRQ, etc) which are fixed by this patch.
r278239:
cxgbe(4): reserve id for iSCSI upper layer driver.
r278374:
cxgbe(4): tidy up some of the interaction between the Upper Layer
Drivers (ULDs) and the base if_cxgbe driver.
Track the per-adapter activation of ULDs in a new "active_ulds" field.
This was done pretty arbitrarily before this change -- via TOM_INIT_DONE
in adapter->flags for TOM, and the (1 << MAX_NPORTS) bit in
adapter->offload_map for iWARP.
iWARP and hw-accelerated iSCSI rely on the TOE (supported by the TOM
ULD). The rules are:
a) If the iWARP and/or iSCSI ULDs are available when TOE is enabled then
iWARP and/or iSCSI are enabled too.
b) When the iWARP and iSCSI modules are loaded they go looking for
adapters with TOE enabled and enable themselves on that adapter.
c) You cannot deactivate or unload the TOM module from underneath iWARP
or iSCSI. Any such attempt will fail with EBUSY.
Add new socket ioctls SIOC[SG]TUNFIB to set FIB number of encapsulated
packets on tunnel interfaces. Add support of these ioctls to gre(4),
gif(4) and me(4) interfaces. For incoming packets M_SETFIB() should use
if_fib value from ifnet structure, use proper value in gre(4) and me(4).
Differential Revision: https://reviews.freebsd.org/D2462
Remove in_gif.h and in6_gif.h files. They only contain function
declarations used by gif(4). Instead declare these functions in C files.
Also make some variables static.
MFC r276215:
Extern declarations in C files loses compile-time checking that
the functions' calls match their definitions. Move them to header files.
Overhaul if_gre(4).
Split it into two modules: if_gre(4) for GRE encapsulation and
if_me(4) for minimal encapsulation within IP.
gre(4) changes:
* convert to if_transmit;
* rework locking: protect access to softc with rmlock,
protect from concurrent ioctls with sx lock;
* correct interface accounting for outgoing datagramms (count only payload size);
* implement generic support for using IPv6 as delivery header;
* make implementation conform to the RFC 2784 and partially to RFC 2890;
* add support for GRE checksums - calculate for outgoing datagramms and check
for inconming datagramms;
* add support for sending sequence number in GRE header;
* remove support of cached routes. This fixes problem, when gre(4) doesn't
work at system startup. But this also removes support for having tunnels with
the same addresses for inner and outer header.
* deprecate support for various GREXXX ioctls, that doesn't used in FreeBSD.
Use our standard ioctls for tunnels.
me(4):
* implementation conform to RFC 2004;
* use if_transmit;
* use the same locking model as gre(4);

MFC r274289 (by bz):
gcc requires variables to be initialised in two places. One of them
is correctly used only under the same conditional though.
For module builds properly check if the kernel supports INET or INET6,
as otherwise various mips kernels without IPv6 support would fail to build.
MFC r274964:
Add ip_gre.h to ObsoleteFiles.inc.
r277637, and r283149 (by emaste@).
r276485 is the real change here, the rest deal with the fallout of
mp_ring's reliance on 64b atomics.
Use the incorrectly spelled 'eigth' from struct pkthdr in this branch
instead of MFC'ing r261733, which would have renamed the field of a
public structure in a -STABLE branch.

r276480:
Temporarily unplug cxgbe(4) from !amd64 builds.
r276485:
cxgbe(4): major tx rework.
a) Front load as much work as possible in if_transmit, before any driver
lock or software queue has to get involved.
b) Replace buf_ring with a brand new mp_ring (multiproducer ring). This
is specifically for the tx multiqueue model where one of the if_transmit
producer threads becomes the consumer and other producers carry on as
usual. mp_ring is implemented as standalone code and it should be
possible to use it in any driver with tx multiqueue. It also has:
- the ability to enqueue/dequeue multiple items. This might become
significant if packet batching is ever implemented.
- an abdication mechanism to allow a thread to give up writing tx
descriptors and have another if_transmit thread take over. A thread
that's writing tx descriptors can end up doing so for an unbounded
time period if a) there are other if_transmit threads continuously
feeding the sofware queue, and b) the chip keeps up with whatever the
thread is throwing at it.
- accurate statistics about interesting events even when the stats come
at the expense of additional branches/conditional code.
The NIC txq lock is uncontested on the fast path at this point. I've
left it there for synchronization with the control events (interface
up/down, modload/unload).
c) Add support for "type 1" coalescing work request in the normal NIC tx
path. This work request is optimized for frames with a single item in
the DMA gather list. These are very common when forwarding packets.
Note that netmap tx in cxgbe already uses these "type 1" work requests.
d) Do not request automatic cidx updates every 32 descriptors. Instead,
request updates via bits in individual work requests (still every 32
descriptors approximately). Also, request an automatic final update
when the queue idles after activity. This means NIC tx reclaim is still
performed lazily but it will catch up quickly as soon as the queue
idles. This seems to be the best middle ground and I'll probably do
something similar for netmap tx as well.
e) Implement a faster tx path for WRQs (used by TOE tx and control
queues, _not_ by the normal NIC tx). Allow work requests to be written
directly to the hardware descriptor ring if room is available. I will
convert t4_tom and iw_cxgbe modules to this faster style gradually.
r276498:
cxgbe(4): remove buf_ring specific restriction on the txq size.
r277225:
Make cxgbe(4) buildable with the gcc in base.
r277226:
Allow cxgbe(4) to be built on i386. Driver attach will succeed only on
a subset of i386 systems.
r277227:
Plug cxgbe(4) back into !powerpc && !arm builds, instead of building it
on amd64 only.
r277230:
Build cxgbe(4) on powerpc64 too.
r277637:
Make sure the compiler flag to get cxgbe(4) to compile with gcc is used
only when gcc is being used. This is what r277225 should have been.
Rename the kld for oce(4) to if_oce.ko. ifconfig(8) has special knowledge
about kld filenames for network drivers that requires them to follow the
pattern of if_<foo>. This also fixes the existing documentation in the
manpage which says to use if_oce_load=YES in loader.conf.

Various fixes for suspend and resume of PCI to PCI and PCI to Cardbus
bridges.
274633:
Remove stray empty comment. The code is adequately explained in the
block comment above, so there's nothing to add here.
274639:
Modernize comments about BIOSes being lame since in this detail they
aren't lame, the rules changed along the way. Catch up to 1999 or so
with the new rules.
274663:
Fix typo pointed out by avg@ and Joerg Sonnenberger. Add a clarifying
sentence too.
277233:
Suspend and resume were the only two functions not to follow the brdev
convention here, so fix that.
277234:
Move the suspsned and resume functions to the bus attachment. They
were accessing PCI config registers, which won't work for the ISA
version.
277235:
Always enable I/O, memory and dma cycles. Some BIOSes don't enable
them, sometimes they are reset for power state transitions or during
whatever happens while suspended. Also, it is good practice to always
do this.
281870:
Cosmetic change: use PCIR_SECLAT_2 rather than PCIR_SECLAT_1.
281871:
The minimim grant and maximum latency PCI config registers are only valid
for type 0 devices, not type 1 or 2 bridges. Don't read them for bridge
devices during bus scans and return an error when attempting to read them
as ivars for bridge devices.
281873:
Don't explicitly manage power states for PCI-PCI bridge devices in the
driver's suspend and resume routines. These have been redundant no-ops
since r214065 changed the PCI bus driver to manage power states for
all devices (including type 1/2 bridge devices) during suspend and resume.
281874:
Update the pci_cfg_save/restore routines to operate on bridge devices
(type 1 and type 2) as well as leaf devices (type 0). In particular,
this allows the existing PCI bus logic to save and restore capability
registers such as MSI and PCI-express work for bridge devices rather than
requiring that code to be duplicated in bridge drivers. It also means
that bridge drivers no longer need to save and restore basic registers
such as the PCI command register or BARs nor manage powerstates for the
bridge device.
While here, pci_setup_secbus() has been changed to initialize the 'sec'
and 'sub' fields in the 'secbus' structure instead of requiring the pcib
and pccbb drivers to do this in the NEW_PCIB + PCI_RES_BUS case.
- Virtualize interface cloner for gre(4). This fixes a panic when destroying
a vnet jail which has a gre(4) interface.
- Make net.link.gre.max_nesting vnet-local.
Fix for control endpoint handling in the DWC OTG driver. The data
stage processing is only allowed after the setup complete event has
been received. Else a race may occur and the OUT data can be corrupted.
While at it ensure resetting a FIFO has the required wait loop.
Merge 278459,278460,278461,278462 which define DTBDIR and other things
needed for install to work. Although the commit in head kinda fixed
install_as_user, it's unknown if that works in 10.x (it didn't the last
time I tried).
- Updated all files with 2015 Avago copyright, and updated LSI's copyright
dates.
- Changed all of the PCI device strings from LSI to Avago Technologies (LSI).
- Added a sysctl variable to control how StartStopUnit behavior works. User can
select to spin down disks based on if disk is SSD or HDD.
- Inquiry data is required to tell if a disk will support SSU at shutdown or
not. Due to the addition of mprssas_async, which gets Advanced Info but not
Inquiry data, the setting of supports_SSU was moved to the
mprsas_scsiio_complete function, which snoops for any Inquiry commands. And,
since disks are shutdown as a target and not a LUN, this process was
simplified by basing it on targets and not LUNs.
- Added a sysctl variable that sets the amount of time to retry after sending a
failed SATA ID command. This helps with some bad disks and large disks that
require a lot of time to spin up. Part of this change was to add a callout to
handle timeouts with the SATA ID command. The callout function is called
mprsas_ata_id_timeout(). (Fixes PR 191348)
- Changed the way resets work by allowing I/O to continue to devices that are
not currently under a reset condition. This uses devq's instead of simq's and
makes use of the MPSSAS_TARGET_INRESET flag. This change also adds a function
called mprsas_prepare_tm().
- Some changes were made to reduce code duplication when getting a SAS address
for a SATA disk.
- Fixed some formatting and whitespace.
- Bump version of mpr driver to 9.255.01.00-fbsd

The NFS client wasn't handling getdirentries(2) requests for sizes
that are not an exact multiple of DIRBLKSIZ correctly. Fortunately
readdir(3) always uses an exact multiple of DIRBLKSIZ, so few applications
were affected. This patch fixes this problem by reducing the size
of the directory read to an exact multiple of DIRBLKSIZ.
Add CAP_FCNTL to the lease file capsicum rights, and limit to
CAP_FCNTL_GETFL. Without CAP_FCNTL_GETFL, the lease file truncation
in rewrite_client_leases() will fail to trim old data when rewriting
the file with a lesser amount of data.
Add 3wire and std as terminal types/classes. These are similar to
the existing terminal types/classes that have the baudrate suffix,
but differ in that no baudrate is set/defined.
Remove trailing whitespaces.
MFC r283785:
Require the embedded packet to contain 8 bytes after the IP header instead
of only 4. This is guaranteed by RFC 792 and the verification of GRE, ICMP

There is no payload anymore. So compute the minimum packet length
correctly and use 40 as the default (if the minumum allows it), as

Extend the maximum number of allowed PCM channels in a PCM stream to
127 and decrease the maximum number of sub-channels to 1. These
definitions are only used inside the kernel and can be changed later
if more than one sub-channel is desired. This has been done to allow
so-called USB audio rack modules to work with FreeBSD.
Add support for more than 8 audio channels per PCM stream for USB
audio class compliant devices under FreeBSD. Tested using 16 recording
and 16 playback audio channels simultaneously.
Bump the FreeBSD version to force recompiling all external modules.
It's common for multi-threaded processes to create a thread for
the purpose of synchronously processing signals. Allow such processes to
utilize a capabilities sandbox.
- Remove mac_get_fd/mac_set_fd - those are not syscalls. The
__mac_get_fd() and __mac_set_fd() syscalls are listed earlier.
- Correct typo in syscall name. It should be sched_rr_get_interval,
not sched_rr_getinterval.
In the reply to SADB_X_SPDGET message use the same sequence number that
was in the request. Some IKE deamons expect it will the same. Linux and
NetBSD also follow this behaviour.

Various updates to the ftruncate(2) documentation:
- Note that ftruncate(2) can operate on shared memory objects and cross
reference shm_open(2).
- Note that ftruncate(2) does not change the file position pointer (aka
seek pointer) of the file descriptor.
- ftruncate(2) will fail with EINVAL for all sorts of other fd types than
just sockets, so instead note that it fails for all but regular files and
shared memory objects.
- Note that ftruncate(2) also appeared in 4.2BSD along with truncate(2).
(Or at least the manpage for both appeared in 4.2, I did not check the
kernel code itself to see if either predated 4.2.)

Remove THRMISC_VERSION. The thrmisc structure doesn't include a version
number, so this wasn't used (and can't easily be added). If at some point
we want to extend thrmisc, we will probably need to just add a new note

Move the 32-bit compatible procfs types from freebsd32.h to <sys/procfs.h>
and export them to userland.
- Define __HAVE_REG32 on platforms that define a reg32 structure and check
for this in <sys/procfs.h> to control when to export prstatus32, etc.
- Add prstatus32_t and prpsinfo32_t typedefs for the 32-bit structures.
libbfd looks for these types, and having them fixes 'gcore' in gdb of a
32-bit process on a 64-bit platform.
- Use the structure definitions from <sys/procfs.h> in gcore's elf32 core
dump code instead of duplicating the definitions.
