Remove the "funny targets" make check. We no longer need embedded :: targets
to build FreeBSD (they are used in Perl man pages). We never needed embedded
"!" in targets that I can find.
We got this from OpenBSD and I cannot find any other make that supports
such things -- contrary to their commit message claim: "This behaviour
is also consistent with other versions of make.".
Now that our assembler supports the xsave family of instructions, use them
natively rather than hand-assembled versions. For xgetbv/xsetbv, add a
wrapper API to deal with xcr* registers: rxcr() and load_xcr().
Correct an error in r237513. The call to reserve_pv_entries() must come
before pmap_demote_pde() updates the PDE. Otherwise, pmap_pv_demote_pde()
can crash.
Add support for the 'xsave', 'xrstor', 'xsaveopt', 'xgetbv', and 'xsetbv'
instructions. I reimplemented this from scratch based on the Intel
manuals and the existing support for handling the fxsave and fxrstor
instructions. This will let us use these instructions natively with GCC
rather than hardcoding the opcodes in hex.
Make use of GEOM Gate direct reads feature. This allows HAST to serve
reads with native speed of the underlying provider.
There are three situations when direct reads are not used:
1. Data is being synchronized and synchronization source is the secondary
node, which means secondary node has more recent data and we should read
from it.
2. Local read failed and we have to try to read from the secondary node.
3. Local component is unavailable and all I/O requests are served from the
secondary node.
Extend GEOM Gate class to handle read I/O requests directly within the kernel.
This will allow HAST to read directly from the local component without
even communicating userland daemon.
Prefer sysctl to open/read/close for obtaining random data.
This method is more sandbox-friendly and also should be faster as only
one syscall is needed instead of three.
In case of an error fall back to the old method.
Use correct part of the Master-Key for generating encryption keys.
Before this change the IV-Key was used to generate encryption keys,
which was incorrect, but safe - for the XTS mode this key was unused
anyway and for CBC mode it was used differently to generate IV
vectors, so there is no risk that IV vector collides with encryption
key somehow.
Bump version number and keep compatibility for older versions.
- Change --nthreads parameter to --parallel for GNU compatibility
- Change default sort method to mergesort, which has a better worst case
performance than qsort
Add the possibility to specify a threshold for the number of negative cache
results required to have the cache return lookup failure.
A new configuration parameter is introduced, which must be set to a value
greater than 1 to activate this feature. The default behavior is unchanged.
The purpose of this change is to allow probes for the existence of an entry
(which are expected to fail), before that entry is added to one of the
queried databases, without the cache returning the stale information from
the probe query until that cache entry expires. If, for example, a new user
account is created after checking that the new account name is available,
the negative cache entry would prevent immediate access to the account.
For that example, the new configuration option
negative-confidence-threshold passwd 2
will require a second negative query result to consider the negative cache
entry for a passwd entry valid, but if the user account has been created
between the queries, then the positive query result from the second query
will be cached and returned.
When ip_output()/ip6_output() is supplied a struct route *ro argument,
it skips FLOWTABLE lookup. However, the non-NULL ro has dual meaning
here: it may be supplied to provide route, and it may be supplied to
store and return to caller the route that ip_output()/ip6_output()
finds. In the latter case skipping FLOWTABLE lookup is pessimisation.
The difference between struct route filled by FLOWTABLE and filled
by rtalloc() family is that the former doesn't hold a reference on
its rtentry. Reference is hold by flow entry, and it is about to
be released in future. Thus, route filled by FLOWTABLE shouldn't
be passed to RTFREE() macro.
- Introduce new flag for struct route/route_in6, that marks route
not holding a reference on rtentry.
- Introduce new macro RO_RTFREE() that cleans up a struct route
depending on its kind.
- All callers to ip_output()/ip6_output() that do supply non-NULL
but empty route should use RO_RTFREE() to free results of
lookup.
- ip_output()/ip6_output() now do FLOWTABLE lookup always when
ro->ro_rt == NULL.
Fix panics triggered by older mfiutil binaries run on the new mfi(4) driver.
The new driver changed the size of the mfi_dcmd_frame structure in such a
way that a MFI_IOC_PASSTHRU ioctl from an old amd64 binary is treated as an
MFI_IOC_PASSTHRU32 ioctl in the new driver. As a result, the user pointer
is treated as the buffer length. mfi_user_command() doesn't have a bounds
check on the buffer length, so it passes a really big value to malloc()
which panics when it tries to exhaust the kmem_map. Fix this two ways:
- Only honor MFI_IOC_PASSTHRU32 if the binary has the SV_ILP32 flag set,
otherwise treat it as an unknown ioctl.
- Add a bounds check on the buffer length passed by the user. For now
it fails any user attempts to use a buffer larger than 1MB.
While here, fix a few other nits:
- Remove an unnecessary check for a NULL return from malloc(M_WAITOK).
- Use the ENOTTY errno for invalid ioctl commands instead of ENOENT.
- Make ipfw's sched rules case insensitive, for user-friendliness.
- Add a note to the ipfw(8) man page about the rules no longer being
case sensitive.
- Fix some typos in the man page.

Begin abstracting out the RX path in preparation for RX EDMA support.
The RX EDMA support requires a modified approach to the RX descriptor
handling.
Specifically:
* There's now two RX queues - high and low priority;
* The RX queues are implemented as FIFOs; they're now an array of pointers
to buffers;
* .. and the RX buffer and descriptor are in the same "buffer", rather than
being separate.
So to that end, this commit abstracts out most of the RX related functions
from the bulk of the driver. Notably, the RX DMA/buffer allocation isn't
updated, primarily because I haven't yet fleshed out what it should look
like.
Whilst I'm here, create a set of matching but mostly unimplemented EDMA
stubs.
Tested:
* AR9280, station mode
TODO:
* Thorough AP and other mode testing for non-EDMA chips;
* Figure out how to allocate RX buffers suitable for RX EDMA, including
correctly setting the mbuf length to compensate for the RX descriptor
and completion status area.
Add a driver for the Freescale FCM module in the localbus controller.
This driver does not yet handle multiple chip selects properly.
Note that the NAND infrastructure does not perform full page
reads or writes, which means that this driver cannot make use
of the hardware ECC that is otherwise present.
Support lbc interrupts:
o Save and clear the LTESR register in the interrupt handler.
o In lbc_read_reg(), return the saved LTESR register value if applicable
(i.e. when the saved value is not invalid (read: ~0U)).
o In lbc_write_reg(), clear the bits in the saved register when when it's
written to and when the asved value is not invalid.
o Also in lbc_write_reg(), the LTESR register is unlocked (in H/W) when
bit 1 of LTEATR is cleared. We use this to invalidate our saved LTESR
register value. Subsequent reads and write go to H/W directly.
While here:
o In lbc_read_reg() & lbc_write_reg(), add some belts and suspenders to
catch when register offsets are out of range.
o In lbc_attach(), initialize completely and don't leave something left
for lbc_banks_enable().
Properly implement bus_setup_intr so that it handles the configuration
of interrupts of direct children. Have the bus_config_intr and
bus_teardown_intr methods implemented by bus_generic_config_intr and
bus_generic_teardown_intr (resp) as we don't need to do anything
special outselves.
This removes all the ``#ifdef $arch'' code that was there because powerpc
didn't have a proper nexus and people tend to copy and paste stuff.
Properly implement the bus_config_intr, bus_setup_intr and bus_teardown_intr
methods so that MI drvers can depend on us doing the right thing instead
of having to go around us and call MD code directly. See the FDT code for
example (not for long though).
Unfortunately the change in r237958 resulted in s/install/instclean/ due to
the aggressive pattern matching of the :C modifier. I tested build and
install in 2 phases, however with different solutions, resulting in the
breakage. Mea culpa.
The solution is to break out the all: target. This causes a few lines of
code duplication, but now the all: target works as it should, and the
other targets continue to work as they did before.
While I'm here, add a ===> header line to the start of each port build
to make it easier to find/more clear in the logs.
Remove device uart_z8530 and options GEOM_PART_APM from DEFAULTS and instead
add them to GENERIC and GENERIC64. They are applicable to Apple H/W and not
at all for Book-E platforms.
Fix a typo that resulted in or-ing PTE_UW twice whrn PTE_SW was needed.
Note that setting the PTE_MODIFIED bit based on whether write is possible
is incorrect. We should set PTE_MODIFIED based on whether the access
is a write operation.
Extend the KPI to lock and unlock f_offset member of struct file. It
now fully encapsulates all accesses to f_offset, and extends f_offset
locking to other consumers that need it, in particular, to lseek() and
variants of getdirentries().
Ensure that on 32bit architectures f_offset, which is 64bit quantity,
always read and written under the mtxpool protection. This fixes
apparently easy to trigger race when parallel lseek()s or lseek() and
read/write could destroy file offset.
The already broken ABI emulations, including iBCS and SysV, are not
converted (yet).
Instruct the firmware not to provision resources for TCP offload if the
kernel is being built without TCP_OFFLOAD. But never override
toecaps_allowed if it has been set manually.
There's no need to make filemon specific to i386 and amd64. All
LP64 architectures define elf64_freebsd_sysvec and all ILP32
architectures define elf32_freebsd_sysvec.
Add a one second sleep before touching the spool directory. If the touch
occurs in the same second as the earlier operations to create the temporary
file and the cron(8) daemon is rescans the spool directory during that
second, then the daemon may miss a cron edit and not properly update its
internal database.
Remove 14 not very useful characters " HDA CODEC PCM" from HDA pcm device
names to shorten them. PulseAudio reported to have problems with names
longer then 63 chars and at least in XMMS long names are inconvinient.
Fix two layout bugs in the previous change:
- Properly increase y_mem when per-CPU stats are enabled.
- Update y_arc for per-CPU stats being enabled/disabled.
Remove route caching from IP multicast routing code. There is no
reason to do that, and also, cached route never got unreferenced,
which meant a reference leak.
Cosmetic display change of Cx states via cx_supported sysctl entries.
Adjust power_profile script to handle the new world order as well.
Some vendors are opting out of a C2 state and only defining C1 & C3. This
leads the acpi_cpu display to indicate that the machine supports C1 & C2
which is caused by the (mis)use of the index of the cx_state array as the
ACPI_STATE_CX value.
e.g. the code was pretending that cx_state[i] would
always convert to i by subtracting 1.
New build KNOB: WITHOUT_PKGBOOTSTRAP to condition building of usr.sbin/pkg
Do not condition usr.sbin/pkg building on WITHOUT_PKGTOOLS anymore, so that users can
remove the old pkg_* tools without removing the pkgng boostrap
Do not override an error from uiomove() with (non-)error result from
bwrite(). VFS needs to know about EFAULT from uiomove() and does not
care much that partially filled block writeback after EFAULT was
successfull. Early return without error causes short write to be
reported to usermode.
Reported and tested by: andreast
MFC after: 3 weeks
Add acpi_asus_wmi(4) -- driver for random extras found on WMI-compatible
Asus laptops. It is alike to acpi_asus(4), but uses WMI interface instead
of separate ACPI device.
On Asus EeePC T101MT netbook it allows to handle hotkeys and on/off WLAN,
Bluetooth, LCD backlight, camera, cardreader and touchpad.
On Asus UX31A ultrabook it allows to handle hotkeys, on/off WLAN, Bluetooth,
Wireless LED, control keyboard backlight brightness, monitor temperature
and fan speed. LCD brightness control doesn't work now for unknown reason,
possibly requiring some video card initialization.
For the ports modules building code, clean WRKDIR before building. This is
important for those that use -DNO_CLEAN routinely, since it will prevent
installing stale stuff, and even more important when the port is upgraded
to a newer version. When the user doesn't use -DNO_CLEAN, this will create
an infinitesimal amount of extra work, but won't hurt anything.
This is necessary because the ports tree has flags that prevent the ususal
'update the build if newer source files exist' logic from doing what it
would do in the base.
ctype_l(3): Note that not all these functions are specified by POSIX.1-2008.
The function isascii_l() is not in POSIX even though isascii() is,
probably because isascii() is marked as obsolete. The other functions,
like digittoint_l() and ishexnumber_l(), are FreeBSD-specific just like
their non-_l versions.
