16 years agoOur fts(3) API, as inherited from 4.4BSD, suffers from integer
yar [Sat, 26 Jan 2008 17:09:40 +0000 (17:09 +0000)]
Our fts(3) API, as inherited from 4.4BSD, suffers from integer
fields in FTS and FTSENT structs being too narrow.  In addition,
the narrow types creep from there into fts.c.  As a result, fts(3)
consumers, e.g., find(1) or rm(1), can't handle file trees an ordinary
user can create, which can have security implications.

To fix the historic implementation of fts(3), OpenBSD and NetBSD
have already changed <fts.h> in somewhat incompatible ways, so we
are free to do so, too.  This change is a superset of changes from
the other BSDs with a few more improvements.  It doesn't touch
fts(3) functionality; it just extends integer types used by it to
match modern reality and the C standard.

Here are its points:

o For C object sizes, use size_t unless it's 100% certain that
  the object will be really small.  (Note that fts(3) can construct
  pathnames _much_ longer than PATH_MAX for its consumers.)

o Avoid the short types because on modern platforms using them
  results in larger and slower code.  Change shorts to ints as
  follows:

- For variables than count simple, limited things like states,
  use plain vanilla `int' as it's the type of choice in C.

- For a limited number of bit flags use `unsigned' because signed
  bit-wise operations are implementation-defined, i.e., unportable,
  in C.

o For things that should be at least 64 bits wide, use long long
  and not int64_t, as the latter is an optional type.  See
  FTSENT.fts_number aka FTS.fts_bignum.  Extending fts_number `to
  satisfy future needs' is pointless because there is fts_pointer,
  which can be used to link to arbitrary data from an FTSENT.
  However, there already are fts(3) consumers that require fts_number,
  or fts_bignum, have at least 64 bits in it, so we must allow for them.

o For the tree depth, use `long'.  This is a trade-off between making
  this field too wide and allowing for 64-bit inode numbers and/or
  chain-mounted filesystems.  On the one hand, `long' is almost
  enough for 32-bit filesystems on a 32-bit platform (our ino_t is
  uint32_t now).  On the other hand, platforms with a 64-bit (or
  wider) `long' will be ready for 64-bit inode numbers, as well as
  for several 32-bit filesystems mounted one under another.  Note
  that fts_level has to be signed because -1 is a magic value for it,
  FTS_ROOTPARENTLEVEL.

o For the `nlinks' local var in fts_build(), use `long'.  The logic
  in fts_build() requires that `nlinks' be signed, but our nlink_t
  currently is uint16_t.  Therefore let's make the signed var wide
  enough to be able to represent 2^16-1 in pure C99, and even 2^32-1
  on a 64-bit platform.  Perhaps the logic should be changed just
  to use nlink_t, but it can be done later w/o breaking fts(3) ABI
  any more because `nlinks' is just a local var.

This commit also inludes supporting stuff for the fts change:

o Preserve the old versions of fts(3) functions through libc symbol
versioning because the old versions appeared in all our former releases.

o Bump __FreeBSD_version just in case.  There is a small chance that
some ill-written 3-rd party apps may fail to build or work correctly
if compiled after this change.

o Update the fts(3) manpage accordingly.  In particular, remove
references to fts_bignum, which was a FreeBSD-specific hack to work
around the too narrow types of FTSENT members.  Now fts_number is
at least 64 bits wide (long long) and fts_bignum is an undocumented
alias for fts_number kept around for compatibility reasons.  According
to Google Code Search, the only big consumers of fts_bignum are in
our own source tree, so they can be fixed easily to use fts_number.

o Mention the change in src/UPDATING.

jhb [Fri, 25 Jan 2008 19:44:46 +0000 (19:44 +0000)]
Fix a bug where a thread that hit the race where the sleep timeout fires
while the thread does not hold the thread lock would stop blocking for
subsequent interruptible sleeps and would always immediately fail the
sleep with EWOULDBLOCK instead (even sleeps that didn't have a timeout).

Some background:
- KSE has a facility for allowing one thread to interrupt another thread.
  During this process, the target thread aborts any interruptible sleeps
  much as if the target thread had a pending signal.  Once the target
  thread acknowledges the interrupt, normal sleep handling resumes.  KSE
  manages this via the TDF_INTERRUPTED flag.  Specifically, it sets the
  flag when it sends an interrupt to another thread and clears it when
  the interrupt is acknowledged.  (Note that this is purely a software
  interrupt sort of thing and has no relation to hardware interrupts
  or kernel interrupt threads.)
- The old code for handling the sleep timeout race handled the race
  by setting the TDF_INTERRUPT flag and faking a KSE-style thread
  interrupt to the thread in the process of going to sleep.  It probably
  should have just checked the TDF_TIMEOUT flag in sleepq_catch_signals()
  instead.
- The bug was that the sleepq code would set TDF_INTERRUPT but it was
  never cleared.  The sleepq code couldn't safely clear it in case there
  actually was a real KSE thread interrupt pending for the target thread
  (in fact, the sleepq timeout actually stomped on said pending interrupt).
  Thus, any future interruptible sleeps (*sleep(.. PCATCH ..) or
  cv_*wait_sig()) would see the TDF_INTERRUPT flag set and immediately
  fail with EWOULDBLOCK.  The flag could be cleared if the thread belonged
  to a KSE process and another thread posted an interrupt to the original
  thread.  However, in the more common case of a non-KSE process, the
  thread would pretty much stop sleeping.
- Fix the bug by just setting TDF_TIMEOUT in the sleepq timeout code and
  not messing with TDF_INTERRUPT and td_intrval.  With yesterday's fix to
  fix sleepq_switch() to check TDF_TIMEOUT, this is now sufficient.

16 years agoFix a race in the sleepqueue timeout code that resulted in sleeps not
jhb [Fri, 25 Jan 2008 02:09:38 +0000 (02:09 +0000)]
Fix a race in the sleepqueue timeout code that resulted in sleeps not
being properly cancelled by a timeout.  In general there is a race
between a the sleepq timeout handler firing while the thread is still
in the process of going to sleep.  In 6.x with sched_lock, the race was
largely protected by sched_lock.  The only place it was "exposed" and had
to be handled was while checking for any pending signals in
sleepq_catch_signals().

With the thread lock changes, the thread lock is dropped in between
sleepq_add() and sleepq_*wait*() opening up a new window for this race.
Thus, if the timeout fired while the sleeping thread was in between
sleepq_add() and sleepq_*wait*(), the thread would be marked as timed
out, but the thread would not be dequeued and sleepq_switch() would
still block the thread until it was awakened via some other means.  In
the case of pause(9) where there is no other wakeup, the thread would
never be awakened.

Fix this by teaching sleepq_switch() to check if the thread has had its
sleep canceled before blocking by checking the TDF_TIMEOUT flag and
aborting the sleep and dequeueing the thread if it is set.

rwatson [Wed, 23 Jan 2008 21:15:51 +0000 (21:15 +0000)]
tcp_usrreq.c:1.313 removed tcbinfo locking from tcp_usr_accept(), which
while in principle a good idea, opened us up to a race inherrent to
the syncache's direct insertion of incoming TCP connections into the
"completed connection" listen queue, as it transpires that the socket
is inserted before the inpcb is fully filled in by syncache_expand().
The bug manifested with the occasional returning of 0.0.0.0:0 in the
address returned by the accept() system call, which occurred if accept
managed to execute tcp_usr_accept() before syncache_expand() had copied
the endpoint addresses into inpcb connection state.

Re-add tcbinfo locking around the address copyout, which has the effect
of delaying the copy until syncache_expand() has finished running, as
it is run while the tcbinfo lock is held.  This is undesirable in that
it increases contention on tcbinfo further, but a more significant
change will be required to how the syncache inserts new sockets in
order to fix this and keep more granular locking here.  In particular,
either more state needs to be passed into sonewconn() so that
pru_attach() can fill in the fields *before* the socket is inserted, or
the socket needs to be inserted in the incomplete connection queue
until it is actually ready to be used.

full terminal length can be used for output lines.

Make -l always have the SUSv2 meaning of "check links."
GNU tar changed -l to match SUSv2 a couple of years ago,
so bsdtar no longer needs to pander to this particular GNUism.
