94eec10ab3 Part II: Update system calls for extended attributes. Rebuild of
generated files.
2002-02-10 04:44:37 +00:00

6ca91a055c Part I: Update extended attribute API and ABI:
o Modify the system call syntax for extattr_{get,set}_{fd,file}() so
  as not to use the scatter gather API (which appeared not to be used
  by any consumers, and be less portable), rather, accepts 'data'
  and 'nbytes' in the style of other simple read/write interfaces.
  This changes the API and ABI.

o Modify system call semantics so that extattr_get_{fd,file}() return
  a size_t.  When performing a read, the number of bytes read will
  be returned, unless the data pointer is NULL, in which case the
  number of bytes of data are returned.  This changes the API only.

o Modify the VOP_GETEXTATTR() vnode operation to accept a *size_t
  argument so as to return the size, if desirable.  If set to NULL,
  the size will not be returned.

o Update various filesystems (pseodofs, ufs) to DTRT.

These changes should make extended attributes more useful and more
portable.  More commits to rebuild the system call files, as well
as update userland utilities to follow.

d45677811a o Merge various recent fixes from the MAC branch relating to extattrctl():
- Fix null-pointer dereference introduced when snapshotting
	  was introduced.  This occured because unlike the previous code,
	  vn_start_write() doesn't always return a non-NULL mp, as
	  filesystems may not support the VOP_GETWRITEMOUNT() call.  For
	  now, rely on two pointers, so that vn_finished_write() works
	  properly.
	- Fix locking problems on exit, introduced at some past time,
	  some when snapshots came in, where a vnode might not be
	  unlocked before being vrele'd in various error situations.

a028cfa65d Revise timercounters to use binary fixed point format internally.
The binary format "bintime" is a 32.64 format, it will go to 64.64
when time_t does.

The bintime format is available to consumers of time in the kernel,
and is preferable where timeintervals needs to be accumulated.

This change simplifies much of the magic math inside the timecounters
and improves the frequency and time precision by a couple of bits.

I have not been able to measure a performance difference which was not
a tiny fraction of the standard deviation on the measurements.

156f4c8aea Fixes for alpha pmap on SMP machines:
- Create a private list of active pmaps rather than abusing the list of all
  processes when we need to look up pmaps.  The process list needs a sx lock
  and we can't be getting sx locks in the middle of cpu_switch()
  (pmap_activate() can call pmap_get_asn() from cpu_switch()).  Instead, we
  protect the list with a spinlock.  This also means the list is shorter
  since a pmap can be used by more than one process and we could (at least
  in thoery) dink with pmap's more than once, but now we only touch each
  pmap once when we have to update all of them.
- Wrap pmap_activate()'s code to get a new ASN in an explicit critical section
  so that when it is called while doing an exec() we can't get preempted.
- Replace splhigh() in pmap_growkernel() with a critical section to prevent
  preemption while we are adjusting the kernel page tables.
- Fixes abuse of PCPU_GET(), which doesn't return an L-value.
- Also adds some slight cleanups to the ASN handling by adding some macros
  instead of magic numbers in relation to the ASN and ASN generations.

c6a128a4b9 Fix a race with free'ing vmspaces at process exit when vmspaces are
shared.

Also introduce vm_endcopy instead of using pointer tricks when
initializing new vmspaces.

The race occured because of how the reference was utilized:
  test vmspace reference,
  possibly block,
  decrement reference

When sharing a vmspace between multiple processes it was possible
for two processes exiting at the same time to test the reference
count, possibly block and neither one free because they wouldn't
see the other's update.

6d2dbc9944 + A variety of 23XX changes:
disable MWI on 2300

	based on function code, set an 'isp_port' for the 2312- it's a
	separate instance, but the NVRAM is shared, and the second port's
	NVRAM is at offset 256.

+ Enable RIO operation for LVD SCSI cards. This makes a *big* difference
as even under reasonable load we get batched completions of about 30
commands at a time on, say, an ISP1080.

+ Do 'continuation' mailbox commands- this allows us to specify a work
area within the softc and 'continue' repeated mailbox commands. This is
more or less on an ad hoc basis and is currently only used for firmware
loading (which f/w now loads substantially faster becuase the calling
thread is only woken when all the f/w words are loaded- not for each
one of the 40000 f/w words that gets loaded).

+ If we're about to return from isp_intr with a 'bogus interrupt' indication,
and we're not a 23XX card, check to see whether the semaphore register is
currently *2* (not *1* as it should be) and whether there's an async completion
sitting in outgoing mailbox0. This seems to capture cases of lost fast posting
and RIO interrupts that the 12160 && 1080 have been known to pump out under
extreme load (extreme, as in > 250 active commands).

f0704f5ca1 Major update of the ATA RAID code, part 1:
Overhaul of the attach/detach code and structures, there were some nasty
bugs in the old implementation. This made it possible to collapse the
ATA/ATAPI device control structures into one generic structure.

A note here, the kernel is NOT ready for detach of active devices,
it fails all over in random places, but for inactive devices it works.
However for ATA RAID this works, since the RAID abstration layer
insulates the buggy^H^H^H^H^H^Hfragile device subsystem from the
physical disks.

Proberly detect the RAID's from the BIOS, and mark critical RAID1
arrays as such, but continue if there is enough of the mirror left
to do so.

Properly fail arrays on a live system. For RAID0 that means return EIO,
and for RAID1 it means continue on the still working part of the mirror
if possible, else return EIO.
If the state changes, log this to the console.

Allow for Promise & Highpoint controllers/arrays to coexist on the
same machine. It is not possible to distribute arrays over different
makes of controllers though.

If Promise SuperSwap enclosures are used, signal disk state on the
status LED on the front.

Misc fixes that I had lying around for various minor bugs.

02ad3c7aca Use osigreturn(2) instead of sigreturn(2) plus broken magic for returning
from old signal handlers.  This is simpler and faster, and fixes (new)
sigreturn(2) when %eip in the new signal context happens to match the
magic value (0x1d516).  0x1d516 is below the default ELF text section,
so this probably never broken anything in practice.

locore.s:
In addition, don't build the signal trampoline for old signal handlers
when it is not used.

alpha:
Not fixed, but seems to be even less broken in practice due to more
advanced magic. A false match occurs for register #32 in mc_regs[].
Since there is no hardware register #32, a false match is only possible
for direct calls to sigreturn(2) that happen to have the magic number
in the spare mc_regs[32] field.

ca79facdf4 In the routines vrele() and vput(), we must lock the vnode and
call VOP_INACTIVE before placing the vnode back on the free list.
Otherwise there is a race condition on SMP machines between
getnewvnode() locking the vnode to reclaim it and vrele()
locking the vnode to inactivate it. This window of vulnerability
becomes exaggerated in the presence of filesystems that have
been suspended as the inactive routine may need to temporarily
release the lock on the vnode to avoid deadlock with the syncer
process.

b616625325 Remove bogus assertion in dup2 that can lead to panics when kernel
threads race for a file slot.

dup2(2) incorrectly assumes that if it needs to grow the ofiles
array that it will get what it wants.  This assertion was valid
before we allowed shared filedescriptor tables but is now incorrect.

The assertion can trigger superfolous panics if the thread doing a
dup2 looses a race with another thread while possibly blocked in
the MALLOC call in fdalloc.  Another thread may grab the slot we
are requesting which makes fdalloc return something other than what
we asked for, this will triggering the bogus assertion.

bde
c1d433597e Made osigreturn(2) standard so that SYS_osigreturn can be used in the
signal trampoline for old signals.  The arches that support old signals
currently abuse sigreturn(2) instead.  This mainly complicates things
and slightly breaks the the new sigreturn(2).

COMPAT is too limited to support the correct configuration of osigreturn,
and this commit doesn't attempt to fix it; it just moves the bogusness:
osigreturn() must now be provided unconditionally even on arches that
don't really need it; previously it had to be provided under the bogus
condition defined(COMPAT_43).

199578d7e8 Compile osigreturn() unconditionally since it will always be needed on
some arches and the syscall table is machine-independent.  It was
(bogusly) conditional on COMPAT_43, so this usually makes no difference.

ia64: in addition:
- replace the bogus cloned comment before osigreturn() by a correct one.
  osigreturn() is just a stub fo ia64's.
- fix the formatting of cloned comment before sigreturn().
- fix the return code.  use nosys() instead of returning ENOSYS to get
  the same semantics as if the syscall is not in the syscall table.
  Generating SIGSYS is actually correct here.
- fix style bugs.

powerpc: copy the cleaned up ia64 stub.  This mainly fixes a bogus comment.

5909c8df4d Cleaned up the 0ldSiG magic check before removing it. Just use fuword()
to fetch the magic word instead of useracc() plus a direct access.
This is more efficient as well as simpler and less incorrect:
- it was inefficent because useracc() takes much longer than just
  accessing the data using a correct access method, at least on i386's.
- it was incorrect because direct access is incorrect unless the address
  has been mapped.  This and nearby direct accesses are mostly handled
  better for other arches because they have to be (direct accesses don't
  work).
- using magic in sigreturn is still fundamentally broken because false
  matches are possible.  On i386's, a false match occurs when %eip in a
  new signal context happens to equal the magic value.  This is not
  handled better for other arches.

b0fc10702a Attempt to fixup select(2) and poll(2), this should fix some races with
other threads as well as speed up the interfaces.

To fix the race and accomplish the speedup, remove selholddrop and
pollholddrop.  The entire concept is somewhat bogus because holding
the individual struct file pointers offers us no guarantees that
another thread context won't close it on us thereby removing our
access to our own reference.

Selholddrop and pollholddrop also would do multiple locks and unlocks
of mutexes _per-file_ in the fd arrays to be scanned, this needed to
be sped up.

Instead of using selholddrop and pollholddrop, simply hold the
filedesc lock over the selscan and pollscan functions.  This should
protect us against close(2)'s on the files as reduce the multiple
lock/unlock pairs per fd into a single lock over the filedesc.

5a61ac7f11 Have SIOCGIFCONF return all (if any) AF_INET addresses for the
interfaces we encounter. In Linux, all addresses are returned for
which gifconf handlers are installed. This boils down to AF_DECnet
and AF_INET. We care mostly about AF_INET for now. Adding additional
families is simple enough.

Returning the addresses is important for RPC clients to function
properly. Andrew found in some reference code that the logic that
handles the retransmission looks for an interface that's up and has
an AF_INET address. This obviously failed as we didn't return any
addresses at all.

Note also that with this change we don't return interfaces that don't
have AF_INET addresses, whereas before we returned any interface
present in the system. This is in line with what Linux does (modulo
interfaces with only AF_DECnet addresses of course :-)

4f050b1765 This patch fixes a long standing complaint with soft updates in
which small and/or nearly full filesystems would fail with `file
system full' messages when trying to replace a number of existing
files (for example during a system installation). When the allocation
routines are about to fail with a file system full condition, they
make a call to softdep_request_cleanup() which attempts to accelerate
the flushing of pending deletion requests in an effort to free up
space. In the face of filesystem I/O requests that exceed the
available disk transfer capacity, the cleanup request could take
an unbounded amount of time. Thus, the softdep_request_cleanup()
routine will only try for tickdelay seconds (default 2 seconds)
before giving up and returning a filesystem full error. Under typical
conditions, the softdep_request_cleanup() routine is able to free
up space in under fifty milliseconds.

193014bed9 The Libretto L series has no $PIR table, but does have a _PIR table.
This typo keeps us from properly routing an interrupt for CardBus
bridges on this machine.  So, now we look for $PIR and then _PIR to
cope.  With these changes, the Libretto L1 now works properly.
Evidentally, the idea comes from patch that the Japanese version of
RedHat (or against a Japanese version of Red Hat), but my Japanese
isn't good enough to to know for sure.

started proactively freeing vnodes it would never actually be called with
a dirty vnode, so this situation did not occur prior to the vnlru() code.
Now that we proactively free vnodes when kern.maxvnodes is hit, however,
vclean() winds up with work to do and improperly generates the warnings.

8ff94b6175 Oops, the previous revision (1.35) broke booting from floppies
because the buffers we use could end up spanning a 64k boundary.
Unfortunately it causes too much bloat (228 -> 72 bytes free) to
just reinstate the old malloc() function.

Instead, define a structure that contains all 4 buffers which must
not cross 64k boundaries. We allocate a 64k-aligned instance in
main() using the magic that was in the old boot2 malloc() function.
This brings the free space down to 168 bytes, but that is still
better than it was before revision 1.35 (136 bytes).

4791f4faa9 Back out the hack from rev 1.13 that was done to initiate a bus rescan
at insert time.  When asking gibbs for approval for an MFC, this was
his reply:

1) It leaks memory if it can't allocate a path.

2) It defers allocation of aic->path until the call to scan the
   bus.  This means the path may be NULL when an interrupt occurs
   prior to the call to scan the bus (stray bus reset for instance),
   which will lead to a panic.

3) The driver in current doesn't recover from the failure to allocate
   aic->path.  The driver doesn't check during normal operation if
   the path is NULL, so again a panic will result.

4) aic_cam_rescan calls malloc with M_WAITOK.  aic_cam_rescan is called
   from attach where it isn't necessarily safe to sleep.

5) And most importantly, it co-opts the xpt_periph from the driver level.
   This was never part of the design (xpt_periph used to be static).  Making
   a call of this type may completely confuse the XPT if other XPT operations
   are ongoing.

In the long term, Justin and Warner agreed to implement solution where
CAM itself will initiate the bus rescan if a new bus is added.  For
the time being (and in particular in light of the upcoming 4.5
release), we now have camcontrol available on the boot floppy, and can
have pccardd initiate the rescan through it.

One to notify the system that the MTU for VLAN can be 1500 so the vlan

the error case if the received frame is to long.

The frame size notification came from code in the SIS driver, and
the support for long frames derived from the NetBSD Tulip driver.

b8d6599e4c When downgrading a filesystem from read-write to read-only, operations
involving file removal or file update were not always being fully
committed to disk. The result was lost files or corrupted file data.
This change ensures that the filesystem is properly synced to disk
before the filesystem is down-graded.

This delta also fixes a long standing bug in which a file open for
reading has been unlinked. When the last open reference to the file
is closed, the inode is reclaimed by the filesystem. Previously,
if the filesystem had been down-graded to read-only, the inode could
not be reclaimed, and thus was lost and had to be later recovered
by fsck.  With this change, such files are found at the time of the
down-grade.  Normally they will result in the filesystem down-grade
failing with `device busy'. If a forcible down-grade is done, then
the affected files will be revoked causing the inode to be released
and the open file descriptors to begin failing on attempts to read.

2f096f0e0a The datasheet for the 6710/6722 says that you must use one method to
detect 3.3V cards for the 6710 and another method for the 6722.  This
latter method is also how the 6729/6730 is supposed to detect 3.3V
cards.  This method works great on my Fujitsu Stylistic 500.  Sadly,
it appears that not all laptop makers are as detail oriented as the
folks that made the Stylistic.  IBM Thinkpad 701C and AST Asentia 810N
both hang hard when the 6729 method is used, but at least the thinkpad
works when the 6710 method is used.  The failure mode appears to be any
access to the memory that we've mapped the CIS in causes the machine to
hang until you eject the card.  The Thinkpad, at least, works with this
change, and it doesn't break my Stylistic.

844237b396 SMP Lock struct file, filedesc and the global file list.
Seigo Tanimura (tanimura) posted the initial delta.

I've polished it quite a bit reducing the need for locking and
adapting it for KSE.

Locks:

1 mutex in each filedesc
   protects all the fields.
   protects "struct file" initialization, while a struct file
     is being changed from &badfileops -> &pipeops or something
     the filedesc should be locked.

1 mutex in each struct file
   protects the refcount fields.
   doesn't protect anything else.
   the flags used for garbage collection have been moved to
     f_gcflag which was the FILLER short, this doesn't need
     locking because the garbage collection is a single threaded
     container.
  could likely be made to use a pool mutex.

1 sx lock for the global filelist.

struct file *	fhold(struct file *fp);
        /* increments reference count on a file */

struct file *	fhold_locked(struct file *fp);
        /* like fhold but expects file to locked */

struct file *	ffind_hold(struct thread *, int fd);
        /* finds the struct file in thread, adds one reference and
                returns it unlocked */

struct file *	ffind_lock(struct thread *, int fd);
        /* ffind_hold, but returns file locked */

I still have to smp-safe the fget cruft, I'll get to that asap.

a2d0f7e01a It is required by VOP_CREATE, VOP_MKNOD, VOP_SYMLINK and VOP_MKDIR
that va_mode of the supplied attributes is filled in with a valid
file mode (i.e not VNOVAL, and only ALLPERM bits set). However,
some NFS server op functions didn't guarantee this for all possible
request messages:

If a V3 client chose not include to a mode specification, we could
end up creating an ffs inode with mode 0177777, requiring a manual
fsck on the next reboot. Fix this by setting va_mode to 0 before
calling the VOP if a mode hasn't been supplied by the client.

In nfsrv_symlink(), S_IFMT bits supplied by a V2 client could end
up in the va_mode passed to VOP_SYMLINK with similar effects. We
now use the macro nfstov_mode() to correctly mask the bits.

c6e526cffc When going to sleep, we must save our SPL so that it does not get
lost if some other process uses the lock while we are sleeping. We
restore it after we have slept. This functionality is provided by
a new routine interlocked_sleep() that wraps the interlocking with
functions that sleep. This function is then used in place of the
old ACQUIRE_LOCK_INTERLOCKED() and FREE_LOCK_INTERLOCKED() macros.

641697c62b Fix a few NFSv2 issues that slipped in during the big cleanup. The
semantics of the nfsm_reply() macro were changed so that the caller
has to explicitly handle the V2 error case, whereas before,
nfsm_reply() did a `goto nfsmout' then. A few server ops (setattr,
readlink, create, mkdir) weren't updated to match, so errors in the
V2 case could cause protocol hangs and leaked mbufs.

Correct some comments that describe the old nfsm_reply behaviour.

[older, harmless nit] Remove the unnecessary `nfsmreply0' label in
nfsrv_create(), since for its users, the main `ereply' label does
the same thing.

e41e7ac3ee The macro nfsm_reply() is supposed to allocate a reply in all cases,
but since the nfs cleanup, it hasn't done so in the case where
`error' is EBADRPC. Callers of this macro expect it to initialise
*mrq, and the `nfsmout' exit point expects a reply to be allocated
if error == 0. When nfsm_reply() was called with error = EBADRPC,
whatever junk was in *mrq (often a stale pointer to an old reply
mbuf) would be assumed to be a valid reply and passed to pru_sosend(),
causing a crash sooner or later.

Fix this by allocating a reply even in the EBADRPC case like we
used to do. This bug was specific to -current.

cfacbbda64 I don't think that these modules should export symbols at all. All
intermodule communication is done via kobj calls.  If anything
currently depends on them, let it break so that we can fix it.  Maybe
we'll need to export some of the card_if.c or power_if.c symbols, but
I think those should be in the base kernel (since all *_if.c should be
in the base kernel for just these reasons).

bfc7272806 Make the alpha boot1 work on filesystems that have a block size
larger than 8k. We now use 4k buffers regardless of the filesystem
block size, so there is no longer a static limit.

Simply increasing the buffer size from 8k to 16k as done on the
i386 doesn't work on the alpha, probably because it causes us
to overshoot boot1's 48k runtime memory limit.

2f13afa09c Reverse the sense of EXPORT_SYMS. If EXPORT_SYMS is not

the typical configuration for most device drivers and
standalone modules; only infrastructure modules or those with
special requirements typically need to export symbols.

Don't print the objcopy commands as they are run when converting

been removed from the cache-list as part of a previous unmount.

This would result in panics (page fault in dqflush()) during subsequent

hash do something are active.

This can probably explain a number of weird quota related behaviours.

traps on the first instruction of signal handlers.

In trap.c:syscall(), fake a trace trap if the single-step flag was set

This fixes bogus trace traps after the last instruction of signal handlers.

gdb-4.18 (the version in FreeBSD) still has problems with the program in

2eab148603 Eliminate the use of commons in the kernel and modules,
simplifying the module linking process and eliminating the risks
associated with doubly-defined variables.

Cases where commons were legitimately used (detection of
compiled-in subsystems) have been converted to use sysinits, and
any new code should use this or an equivalent practice as a
matter of course.

Modules can override this behaviour by substituting -fno-common
out of ${CFLAGS} in cases where commons are necessary
(eg. third-party object modules).  Commons will be resolved and
allocated space when the kld is linked as part of the module
build process, so they will not pose a risk to the kernel or
other modules.

Provide a mechanism for controlling the export of symbols from
the module namespace.  The EXPORT_SYMS variable may be set in the
Makefile to NO (export no symbols), a list of symbols to export,
or the name of a file containing a newline-seperated list of
symbols to be exported.  Non-exported symbols are converted to
local symbols.  If EXPORT_SYMS is not set, all global symbols are
currently exported.  This behaviour is expected to change (to
exporting no symbols) once modules have been converted.
