eaa93f5a2f PROBLEM: putting in a loader config file a line of the form
loader_conf_files="foo bar baz"

should cause loading the files listed, and then resume with the
remaining config files (from previous values of the variable).
Unfortunately, sometimes the line was ignored -- actually even
modifying the line in /boot/default/loader.conf  sometimes doesn't work.

ANALYSIS: After much investigation, turned out to be a bug in the logic.
The existing code detected a new assignment by looking at the address
of the the variable containing the string. This only worked by pure
chance, i.e. if the new string is longer than the previous value
then the memory allocator may return a different address
to store the string hence triggering the detection.

SOLUTION: This commit contains a minimal change to fix the problem,
without altering too much the existing structure of the code.
However, as a step towards improving the quality and reliability of
this code, I have introduced a handful of one-line functions
(strget, strset, strfree, string= ) that could be used in dozens
of places in the existing code.

HOWEVER:
There is a much bigger problem here. Even though I am no Forth
expert (as most fellow src committers) I can tell that much of the
forth code (in support.4th at least) is in severe need of a
review/refactoring:

+ pieces of code are replicated multiple times instead of writing
  functions (see e.g.  set_module_*);

+ a lot of stale code (e.g. "structure" definitions for
  preloaded_files, kernel_module, pnp stuff) which is not used
  or at least belongs elsewhere.
  The code bload is extremely bad as the loader runs with very small
  memory constraints, and we already hit the limit once (see

    http://svn.freebsd.org/viewvc/base?view=revision&revision=185132
  Reducing the footprint of the forth files is critical.

+ two different styles of coding, one using pure stack functions
  (maybe beautiful but surely highly unreadable), one using
  high level mechanisms to give names to arguments and local
  variables (which leads to readable code).

Note that this code is used by default by all FreeBSD installations,
so the fragility and the code bloat are extremely damaging.
I will try to work fixing the three items above, but if others have
time, please have a look at these issues.

07e169420f Another, hopefully final set of changes to boot0 and boot0cfg.
boot0.S changes:

+ import a patch from Christoph Mallon to rearrange the various
  print functions and save another couple of bytes;

+ implement the suggestion in PR 70531 to enable booting from
  any valid partition because even the extended partitions that
  were previously in our kill list may contain a valid boot loader.
  This simplifies the code and saves some bytes;

+ followwing up PR 127764, implement conditional code to preserve
  the 'Volume ID' which might be used by other OS (NT, XP, Vista)
  and is located at offset 0x1b8. This requires a relocation of the
  parameter block within the boot sector -- there is no other
  possible workaround.
  To address this, boot0cfg has been updated to handle both
  versions of the boot code;

+ slightly rearrange the strings printed in the menus to make
  the code buildable with all options. Given the tight memory
  budget, this means that with certain options we need to
  shrink or remove certain labels.

and especially:

	make -DVOLUME_LABEL -DPXE the default options.

  This means that the newly built boot0 block will preserve the
  Volume ID, and has the (hidden) option F6 to boot from INT18/PXE.
  I think the extra functionality is well worth the change.

  The most visible difference here is that the 'Default: ' string
  now becomes 'Boot: ' (it can be reverted to the old value
  but then we need to nuke 1/2 partition name or entries to
  make up for the extra room).

boot0cfg changes:

+ modify the code to recognise the new boot0 structure (with the
  relocated options block to make room for the Volume id).

+ add two options, '-i xxxx-xxxx' to set the volume ID, -e c
  to modify the character printed in case of bad input

e0b90fff45 This commits brings in a lot of documentation and some enhancement
of the boot0.S code, with a number of compile-time selectable options,
the most interesting one being the ability to select PXE booting.

The code is completely compatible with the previous one, and with
the boot0cfg program. Even the actual code is largely unmodified,
with only minor rearrangements or fixes to make room for the new
features.

The behaviour of the standard build differs from the previous
version in the following, minor things:

+ 'noupdate' is the default, which means the code does not
  write back the selection to disk. You can enable the feature
  at runtime with boot0cfg, or changing the flags in the Makefile.

+ a drive number of 0x00 (floppy, or USB in floppy emulation) is
  now accepted as valid. Previously, it was overridden with 0x80,
  meaning that the partition table coming from the media was
  used to access sectors on a possibly different media.
  You can revert to the previous mode building with -DCHECK_DRIVE,
  and you can always use the 'setdrv' option in boot0cfg

+ certain FAT or NTFS partitions are listed as WIN instead of DOS.

+ the 'bel' character on a bad selection is replaced by a '#' to
  make it clear that the system is not hang even if the machine
  does not have a speaker. This can be reverted back at compile
  time, or at runtime with an upcoming boot0cfg option.

Additional features are available as compile time options,
and may be become the default if deemed useful. In particular:

+ INT18/PXE boot (make -DPXE)
  This option enables booting through INT 18h (which on certain
  BIOSes can be hooked to PXE) by pressing F6. There is unfortunately
  no room to print the additional menu option.
  Also, to make room for the code, the 'Default: ' string is
  changed to 'Boot: '

+ print current drive number (make -DTEST)
  Prints a line indicating the current drive number.
  This is useful to figure out what is going on for machines/bioses
  which remap drives in sometimes surprising ways.

+ disable numeric keys in console mode (make -DONLY_F_KEYS)
  Not really a significant option, but it is needed to make
  room for the -DTEST mode.

+ disable floppy support (make -DCHECK_DRIVE)
  Revert to the old behaviour of only accepting 0x80 and above
  as valid drive numbers.

e1a8c28b5e Fix a typo in previous commit: must call "putn" to print a crlf,
instead of "puts" which prints whatever is at %si, followed by a CRLF.

It was not noticed during tests because at that point %si points
to a partition entry whose first byte is 0x80, which is both a
terminator for the string and a non printable character.

6d7402ae81 Pass the pointer to the selected partition in %si to the next stage
boot code. The bug was introduced in rev.1.13, and went unnoticed
because FreeBSD's boot1 does not use it, but other systems might.

(I have been struggling for almost a full day trying to figure out
why a syslinux'ed partition would not boot when started with the
FreeBSD /boot/boot0, only to realize that the bug was ours!)

The space for the two extra bytes (push %si and pop %si) is reclaimed
by removing an extra CRLF that is printed before booting.

The bug is not a major one but if there is time it might be a good
thing to merge it into the upcoming releases.

8c1c552ad2 As reported in kern/118222, pxeboot in RELENG7 (and presumably
above) exhibits some misbehaviours on machines with AMD64 CPUs,
which at least in some cases I have tracked down to a heap overflow.

It is unclear whether it depends on the CPU or on the pxe bios
itself which may use more memory on AMD machines.

Noticeably a pxeboot compiled from 6.x sources works fine on all
machines I have tried so far, while a pxeboot compiled from 7.x
sources does not.

This patch is a first step in reducing the amount of memory used
while processing the configuration files read by the loader at boot
(some of them are quite large, 1700+ lines), and it does so by:
+ moving a buffer to static memory instead of allocating in the heap;
+ skipping empty lines;
+ reducing the amount of memory used for line descriptors;

Unfortunately there are several changes between 6.x and above,
affecting the compiler, the loader code itself, and libstand,
and it is not so straightforward to
These changes fix the behaviour on one motherboard with a
single-core AMD cpu, but are still not enough e.g on an Asus
M2N-VM (with a dual-core CPU).

I need to investigate the problem a bit more before figuring
out what should be committed to RELENG_7

- vfs.zfs.super_owner

	Allows regular users to perform privileged operations on files stored
	on ZFS file systems owned by him. Very careful with this one.

- chflags(2)

	Not all the flags are supported. This still needs work.

- ZFSBoot

	Support to boot off of ZFS pool. Not finished, AFAIK.

	Before if write requested failed, system paniced. Now one
	can select from one of three failure modes:
	- panic - panic on write error
	- wait - wait for disk to reappear
	- continue - serve read requests if possible, block write requests

- Refquota, refreservation properties

	Just quota and reservation properties, but don't count space consumed
	by children file systems, clones and snapshots.

- Sparse volumes

	ZVOLs that don't reserve space in the pool.

- External attributes

	Compatible with extattr(2).

8fe107d730 Add ale(4), a driver for Atheros AR8121/AR8113/AR8114 PCIe ethernet
controller. The controller is also known as L1E(AR8121) and
L2E(AR8113/AR8114). Unlike its predecessor Attansic L1,
AR8121/AR8113/AR8114 uses completely different Rx logic such that
it requires separate driver. Datasheet for AR81xx is not available
to open source driver writers but it shares large part of Tx and
PHY logic of L1. I still don't understand some part of register
meaning and some MAC statistics counters but the driver seems to
have no critical issues for performance and stability.

The AR81xx requires copy operation to pass received frames to upper
stack such that ale(4) consumes a lot of CPU cycles than that of
other controller. A couple of silicon bugs also adds more CPU
cycles to address the known hardware bug. However, if you have fast
CPU you can still saturate the link.
Currently ale(4) supports the following hardware features.
  - MSI.
  - TCP Segmentation offload.
  - Hardware VLAN tag insertion/stripping with checksum offload.
  - Tx TCP/UDP checksum offload and Rx IP/TCP/UDP checksum offload.
  - Tx/Rx interrupt moderation.
  - Hardware statistics counters.
  - Jumbo frame.
  - WOL.

AR81xx PCIe ethernet controllers are mainly found on ASUS EeePC or
P5Q series of ASUS motherboards. Special thanks to Jeremy Chadwick
who sent the hardware to me. Without his donation writing a driver
for AR81xx would never have been possible. Big thanks to all people
who reported feedback or tested patches.

45e57c6bd2 USIII and beyond CPUs have stricter requirements when it comes
to synchronization needed after stores to internal ASIs in order
to make side-effects visible. This mainly requires the MEMBAR #Sync
after such stores to be replaced with a FLUSH. We use KERNBASE as
the address to FLUSH as it is guaranteed to not trap. Actually,
the USII synchronization rules also already require a FLUSH in
pretty much all of the cases changed.
We're also hitting an additional USIII synchronization rule which
requires stores to AA_IMMU_SFSR to be immediately followed by a DONE,
FLUSH or RETRY. Doing so triggers a RED state exception though so
leave the MEMBAR #Sync. Linux apparently also has gotten away with
doing the same for quite some time now, apart from the fact that
it's not clear to me why we need to clear the valid bit from the
SFSR in the first place.

15fcbd3b7f - Read ASI_{D,I}TLB_DATA_ACCESS_REG twice in order to work around
errata of USIII and beyond (USIII erratum #19, USIII+ erratum #1,
  USIIIi erratum #1).
- Use the cheetah PA mask in {d,i}tlb_va_to_pa_sun4u() for USIII
  and beyond. This is done so that these functions will still mask
  the debug bits of spitfire-class CPUs once we increase TD_PA_BITS
  to match the number of bits used for the PA by cheetah-class CPUs.
- Change {d,i}tlb_enter_sun4u() to also set TLB_CTX_KERNEL as the
  context of the mappings entered. This is more or less cosmetic as
  TLB_CTX_KERNEL is 0.
- Now that we have to distinguish between different sun4u CPUs in
  the loader anyway, no longer do trial and error when reading the

8735fdbd4c Enable GCC stack protection (aka Propolice) for userland:
- It is opt-out for now so as to give it maximum testing, but it may be
  turned opt-in for stable branches depending on the consensus.  You
  can turn it off with WITHOUT_SSP.
- WITHOUT_SSP was previously used to disable the build of GNU libssp.
  It is harmless to steal the knob as SSP symbols have been provided
  by libc for a long time, GNU libssp should not have been much used.
- SSP is disabled in a few corners such as system bootstrap programs
  (sys/boot), process bootstrap code (rtld, csu) and SSP symbols themselves.
- It should be safe to use -fstack-protector-all to build world, however
  libc will be automatically downgraded to -fstack-protector because it
  breaks rtld otherwise.
- This option is unavailable on ia64.

Enable GCC stack protection (aka Propolice) for kernel:
- It is opt-out for now so as to give it maximum testing.
- Do not compile your kernel with -fstack-protector-all, it won't work.

992f3401a7 Implement a workaround for a long-standing problem in
libi386's time(), caused by a qemu bug.  The bug might
be present in other BIOSes, too.

qemu either does not simulate the AT RTC correctly or
has a broken BIOS 1A/02 implementation, and will return
an incorrect value if the RTC is read while it is being
updated.

The effect is worsened by the fact that qemu's INT 15/86
function ("wait" a.k.a. usleep) is non-implmeneted or
broken and returns immediately, causing beastie.4th to
spin in a tight loop calling the "read RTC" function
millions of times, triggering the problem quickly.

Therefore, we keep reading the BIOS value until we get
the same result twice.  This change fixes beastie.4th's
countdown under qemu.

7e7a99d55a Eliminate artificial increasing of 'netdev_opens' counter in loader's net_open().
This was introduced as a workaround long time ago for some Alpha firmware
(which is now gone), and actually prevented net_close() to ever be
called.

Certain firmwares (U-Boot) need local shutdown operations to be performed on a
network controller upon transaction end: such platform-specific hooks are
supposed to be called via netif_close() (from within net_close()).

This change effectively reverts the following CVS commit:

    sys/boot/common/dev_net.c

    revision 1.7
    date: 2000/05/13 15:40:46;  author: dfr;  state: Exp;  lines: +2 -1
    Only probe network settings on the first open of the network device.
    The alpha firmware takes a seriously long time to open the network device
    the first time.

Also suppress excessive output while netbooting via loader, unless debugging.

While there, make sys/boot/uboot more style(9) compliant.

700cab4d41 Change the BTX kernel to drop all the way out to real mode to invoke BIOS
routines (V86 requests from the client and hardware interrupt handlers):
- Install trampoline real mode interrupt handlers at IDT vectors 0x20-0x2f
  to handle hardware interrupts by invoking the appropriate vector (0x8-0xf
  or 0x70-0x78).  This allows the 8259As to use vectors 0x20-0x2f in real
  mode as well as protected mode will ensuring that the master 8259A
  doesn't share IDT space with CPU exceptions in protected mode.
- Since we don't need to reserve space for page tables and a page directory
  anymore since dropping paging support, move the TSS and protected mode
  IDT up by 16k.  Grow the ring 1 link stack by 16k as a result.
- Repurpose the ring 1 link stack to be used as a real mode stack when
  invoking real mode routines either via a V86 request or a hardware
  interrupts.  This simplifies a few things as we avoid disturbing the
  original user stack.
- Add some more block comments to explain how the code interacts with the
  V86 structure as this wasn't immediately obvious from the prior comments
  (e.g. that we explicitly copy the seg regs for real mode out of the V86
  struct onto the stack to be popped off when going into real mode, etc.).
  Also, document some of the stack frames we create going to real mode and
  back.
- Remove all of the virtual 86 related code including having to simulate
  various instructions and BIOS calls on a trap from virtual 86 mode.
- Explicitly panic if a user client attempts to perform a V86 CALL
  request that isn't a far call.
- Bump version to 1.2.

Assuming this works ok this should fix some of the long standing issues
with USB booting as well as etherboot.

d957274e54 MFi386: part of revision 1.51
Rework the read/write support in the bios disk driver some to cut down
  on duplicated code.
  - All of the bounce buffer and retry logic duplicated in bd_read() and
    bd_write() are merged into a single bd_io() routine that takes an
    extra direction argument.  bd_read() and bd_write() are now simple
    wrappers around bd_io().

7205d51f8d Load the bytes into the EMAC's MAC address register in the proper
order.  The kernel used to shuffle them around to get things right,
but that was recently fixed.  This makes our boot loader match the
behavior of most other boot loaders for the atmel parts.  This bug was
inherited from the Kwikbyte loader that we started from.

This bug was discovered by Bj.ANvrn KNvnig back in June, but fell on the
floor.  He provided patches to the kernel, include backwards
compatibility options that were similar to Olivier's if_ate.c commit.

2f8a906c36 First cut at support for booting a GPT labeled disk via the BIOS bootstrap
on i386 and amd64 machines.  The overall process is that /boot/pmbr lives
in the PMBR (similar to /boot/mbr for MBR disks) and is responsible for
locating and loading /boot/gptboot.  /boot/gptboot is similar to /boot/boot
except that it groks GPT rather than MBR + bsdlabel.  Unlike /boot/boot,
/boot/gptboot lives in its own dedicated GPT partition with a new
"FreeBSD boot" type.  This partition does not have a fixed size in that
/boot/pmbr will load the entire partition into the lower 640k.  However,
it is limited in that it can only be 545k.  That's still a lot better than
the current 7.5k limit for boot2 on MBR.  gptboot mostly acts just like
boot2 in that it reads /boot.config and loads up /boot/loader.  Some more
details:
- Include uuid_equal() and uuid_is_nil() in libstand.
- Add a new 'boot' command to gpt(8) which makes a GPT disk bootable using
  /boot/pmbr and /boot/gptboot.  Note that the disk must have some free
  space for the boot partition.
  - This required exposing the backend of the 'add' function as a
    gpt_add_part() function to the rest of gpt(8).  'boot' uses this to
    create a boot partition if needed.
- Don't cripple cgbase() in the UFS boot code for /boot/gptboot so that
  it can handle a filesystem > 1.5 TB.
- /boot/gptboot has a simple loader (gptldr) that doesn't do any I/O
  unlike boot1 since /boot/pmbr loads all of gptboot up front.  The
  C portion of gptboot (gptboot.c) has been repocopied from boot2.c.
  The primary changes are to parse the GPT to find a root filesystem
  and to use 64-bit disk addresses.  Currently gptboot assumes that the
  first UFS partition on the disk is the / filesystem, but this algorithm
  will likely be improved in the future.
- Teach the biosdisk driver in /boot/loader to understand GPT tables.
  GPT partitions are identified as 'disk0pX:' (e.g. disk0p2:) which is
  similar to the /dev names the kernel uses (e.g. /dev/ad0p2).
- Add a new "freebsd-boot" alias to g_part() for the new boot UUID.

7781c2181a Rework the read/write support in the bios disk driver some to cut down
on duplicated code and support 64-bit LBAs for GPT.
- The code to manage an EDD or C/H/S I/O request are now in their own
  routines.  The EDD routine now handles a full 64-bit LBA instead of
  truncating LBAs to the lower 32-bits.  (MBRs and BSD labels only
  have 32-bit LBAs anyway, so the only LBAs ever passed down were 32-bit).
- All of the bounce buffer and retry logic duplicated in bd_read() and
  bd_write() are merged into a single bd_io() routine that takes an
  extra direction argument.  bd_read() and bd_write() are now simple
  wrappers around bd_io().
- If a disk supports EDD then always use it rather than only using it if
  the cylinder is > 1023.  Other parts of the boot code already do
  something similar to this.  Also, GPT just uses LBAs, so for a GPT disk
  it's probably best to ignore C/H/S completely.  Always using EDD when
  it is supported by a disk is an easy way to accomplish this.

d6e6728367 - Make better use of the global chosen, memory and mmu handles instead
of obtaining them over and over again and pretending we could do
  anything useful without them (for chosen this includes adding a
  declaration and initializing it in OF_init()).
- In OF_init() if obtaining the memory or mmu handle fails just call
  OF_exit() instead of panic() as the loader hasn't initialized the
  console at these early stages yet and trying to print out something
  causes a hang. With OF_exit() one at least has a change to get back
  to the OFW boot monitor and debug the problem.
- Fix OF_call_method() on 64-bit machines (this is a merge of
  sys/dev/ofw/openfirm.c rev 1.6).
- Replace OF_alloc_phys(), OF_claim_virt(), OF_map_phys() and
  OF_release_phys() in the MI part of the loader with wrappers around
  OF_call_method() in the sparc64. Beside the fact that they duplicate
  OF_call_method() the formers should never have been in the MI part
  of the loader as contrary to the OFW spec they use two-cell physical
  addresses.
- Remove unused functions which are also MD dupes of OF_call_method().
- In sys/boot/sparc64/loader/main.c add __func__ to panic strings as
  different functions use otherwise identical panic strings and make
  some of the panic strings a tad more user-friendly instead of just
  mentioning the name of the function that returned an unexpected
  result.
