Be more consistent with how we refer to fopen() - pointed out by wiz@

(kre)

In XEN PV, the idt vector table is not required to be altered at
runtime, since only entries for exceptions/traps are registered with
the hypervisor and interrupts are managed via a completely different
mechanism.

This change uses the idt_vec_reserve() mechanism nevertheless,
modifying it slightly to only do namespace management in XEN, while on
native it will continue to do idt entry init as before.

Rationale: Consistent API usage and potential future merging of
XEN/non-XEN code.

There are no functional changes in this commit.

Don't test for failure of malloc(...,M_WAITOK), it cannot fail

(maya)

Some (mostly minor) wording improvements (IMO)

(kre)

Fix xref. Remove Tn.

(wiz)

Always set XCR0_X87, to force a reload of CW. That's needed for compat
options where fx_cw is not the standard fpu value.

(maxv)

Fix xen. Not tested, but seems fine enough.

(maxv)

Avoid losing a fd (ie: close it) in the (ever so likely) case that the
fd exceeds the limits of what can be stored in a FILE (65535).

(kre)

Put back the tests for "no files matched" (in a different way than they
were written previously - but that's just style.)  This is not csh...

Use the correct test operator to test for an empty file (rather than
testing for an empty file name...)

Write test ('[') commands in a way that is defined to work, rather than
just happens to - we can afford the (negligible) performance hit here.

- don't use command substitution to glob a pattern into a list of filenames;
  it is less efficient than doing it directly and does not handle whitespace
  in filenames properly.

(christos)

be more careful about opening recovery files... in particular deal with
people trying to get 'vi -r' stuck using named pipes, symlink attacks,
and coercing others opening recovery files they did not create.

Don't #ifdef DIAGNOSTIC around KASSERTs.

the definition of KASSERT does the same thing

(skrll)

use kmem, don't check for allocation failure with KM_SLEEP

(maya)

XEN apparently has no fpuinit_mxcsr_mask() and hasn't needed it until
now, so just omit this (as it was before) for XEN.  If this is not
correct, someone who knows x86's & the XEN interface can fix it, but
at least it should build, and be essentially the same as before now.

(kre)

Add WDF_OPEN flag to really disallow opening of a disk that has been invalidated.

Restore wdbiorestart function to actually retry the failed I/O request instead
of just restarting the queue.

Fix compilation without ATADEBUG.

(mlelstv)

Handle absolute relocations coming from the kernel: preserve SHN_ABS in

Update the kernhist(9) kernel history code to address issues identified
in PR kern/52639, as well as some general cleaning-up...
(As proposed on tech-kern@ with additional changes and enhancements.)
Details of changes:
* All history arguments are now stored as uintmax_t values[1], both in
  the kernel and in the structures used for exporting the history data
  to userland via sysctl(9).  This avoids problems on some architectures
  where passing a 64-bit (or larger) value to printf(3) can cause it to
  process the value as multiple arguments.  (This can be particularly
  problematic when printf()'s format string is not a literal, since in
  that case the compiler cannot know how large each argument should be.)
* Update the data structures used for exporting kernel history data to
  include a version number as well as the length of history arguments.
* All [2] existing users of kernhist(9) have had their format strings
  updated.  Each format specifier now includes an explicit length
  modifier 'j' to refer to numeric values of the size of uintmax_t.
* All [2] existing users of kernhist(9) have had their format strings
  updated to replace uses of "%p" with "%#jx", and the pointer
  arguments are now cast to (uintptr_t) before being subsequently cast
  to (uintmax_t).  This is needed to avoid compiler warnings about
  casting "pointer to integer of a different size."
* All [2] existing users of kernhist(9) have had instances of "%s" or
  "%c" format strings replaced with numeric formats; several instances
  of mis-match between format string and argument list have been fixed.
* vmstat(1) has been modified to handle the new size of arguments in the
  history data as exported by sysctl(9).
* vmstat(1) now provides a warning message if the history requested with
  the -u option does not exist (previously, this condition was silently
  ignored, with only a single blank line being printed).
* vmstat(1) now checks the version and argument length included in the
  data exported via sysctl(9) and exits if they do not match the values
  with which vmstat was built.
* The kernhist(9) man-page has been updated to note the additional
  requirements imposed on the format strings, along with several other
  minor changes and enhancements.
[1] It would have been possible to use an explicit length (for example,
    uint64_t) for the history arguments.  But that would require another
    "rototill" of all the users in the future when we add support for an
    architecture that supports a larger size.  Also, the printf(3)
format
    specifiers for explicitly-sized values, such as "%"PRIu64, are much
    more verbose (and less aesthetically appealing, IMHO) than simply
    using "%ju".
[2] I've tried very hard to find "all [the] existing users of
kernhist(9)"
    but it is possible that I've missed some of them.  I would be glad
to
    update any stragglers that anyone identifies.
--
For some reason this single kernel seems to have outgrown its declared
size as a result of the kernhist(9) changes.  Bump the size.
XXX The amount of increase may be excessive - anyone with more detailed
XXX knowledge please feel free to further adjust the value
appropriately.
--
Misssed one cast of pointer --> uintptr_t in previous kernhist(9) commit
--
And yet another one.  :(
--
Use correct mark-up for NetBSD version.
--
More improvements in grammar and readability.
--
Remove a stray '"' (obvious typo) and add a couple of casts that are
probably needed.
--
And replace an instance of "%p" conversion with "%#jx"
--
Whitespace fix. Give Bl tag table a width. Fix Xr.

Revert previous on demand.

Rationale:

The DSO handle is a required part of the (external) __cxa_atexit interface.
The atexit mapping is an implementation detail and not part of the public
interface. Doing it directly creates UB as it involves casting function
pointers between incompatible types.

  -- Joerg

(kamil)

Correct handling of __cxa_atexit(a,b,NULL) in libc

In the NetBSD implementation and suggested by Itanium C++ ABI, we wrap
the atexit(x) call as __cxa_atexit(x,NULL,NULL).

__cxa_atexit() is an internal function for the usage of C++.

Correct a bug that __cxa_atexit(x,y,NULL) is handled in the same way as
atexit(x) (which is simplified to __cxa_atexit(x,NULL,NULL).

This misbehavior has been detected in the Thread Sanitizer port to NetBSD.

Implement it in a few tty drivers. If this flag is set, the underlying

No need to pull-up to -8 - the extra cast really won't hurt anything.

Fix npfclt reload on rump kernels

It fails because npfctl cannot get an errno when it calls ioctl to the (rump)
kernel; npfctl (libnpf) expects that an errno is returned via proplib,
however, the rump library of npf doesn't so. It happens because of mishandlings
of complicate npf kernel options.

Provisionally return to declaring midi_cd unconditionally.

Apparently this breaks compiling some kernels, although how they ever
managed to link if midi_cd is not declared in ioconf.h, and therefore
presumably not defined in ioconf.c, is beyond me.

Maybe someone who knows how sequencer is supposed to work, and/or
someone who knows how arm kernels are linked, can figure this out...

Randomize the kernel segments independently. That is to say, put text,
rodata and data at different addresses (and in a random order).

To achieve that, the mapping order in the prekern is changed. Until now,
we were creating the kernel map the following way:
-> choose a random VA
-> map [kernpa_start; kernpa_end[ at this VA
-> parse the ELF structures from there
-> determine where exactly the kernel segments are located
-> relocate etc
Now, we are doing:
-> create a read-only view of [kernpa_start; kernpa_end[
-> from this view, compute the size of the "head" region
-> choose a random VA in the HEAD window, and map the head there
-> for each region in (text, rodata, data, boot)
-> compute the size of the region from the RO view
-> choose a random VA in the KASLR window
-> map the region there
-> relocate etc

Each time we map a region, we initialize its bootspace fields right away.

The "head" region must be put before the other regions in memory, because
the kernel uses (headva + sh_offset) to get the addresses of the symbols,
and the offset is unsigned.

Given that the head does not have an mcmodel constraint, its location is
randomized in a window located below the KASLR window.

The rest of the regions being in the same window, we need to detect
collisions.

Note that the module map is embedded in the "boot" region, and that
therefore its location is randomized too.

(maxv)

Use bootspace.head.va instead of the direct map. Otherwise there's the
assumption that the offsets contained in sh_offset in physical memory are
equal to the offsets in virtual memory, which won't be true in the future.

(maxv)

Add three functions and start using them; will be more useful soon.

(maxv)

Add a fifth region, called "head". On kaslr kernels it contains the ELF
Header and the ELF Section Headers. On normal kernels it is empty (the
headers are in the "boot" region).

Note: if you're using GENERIC_KASLR, you also need to rebuild the prekern.

Misssed one cast of pointer --> uintptr_t in previous kernhist(9) commit

(pgoyette)

It appears that Xen remaps the userland %cs to 0xE033. So add it to the
checklist. Otherwise we're going through Luexit32: %fs gets reloaded,
which sets the FS.base to NULL, which will cause the thread to page-fault
next time it accesses its TLS (as seen in PR/52662).

This fix is not very clean, and it would be nice to understand why Xen
remaps %cs. But I'm committing it now anyway, so that people can test.

(maxv)

Fix a mistake I made in the very first revision. The calculation of the
number of slots was incorrect in some cases, and it could cause the
prekern to fault right away at boot time, or the kernel to fault when
loading kernel modules near the end of the module map.

The variables are divided by PAGE_SIZE to prevent integer overflows.

Allow only one pending call to a pool's backing allocator at a time.

Candidate fix for problems with hanging after kva fragmentation related
to PR kern/45718.

Proposed on tech-kern:

https://mail-index.NetBSD.org/tech-kern/2017/10/23/msg022472.html

Tested by bouyer@ on i386.

This makes one small change to the semantics of pool_prime and
pool_setlowat: they may fail with EWOULDBLOCK instead of ENOMEM, if
there is a pending call to the backing allocator in another thread but
we are not actually out of memory.  That is unlikely because nearly
always these are used during initialization, when the pool is not in
use.
