christos | add a kauth vnode check for creating links
|

| 20-Oct-2021 |
thorpej | Overhaul of the EVFILT_VNODE kevent(2) filter:
- Centralize vnode kevent handling in the VOP_*() wrappers, rather than
forcing each individual file system to deal with it (except VOP_RENAME(),
because VOP_RENAME() is a mess and we currently have 2 different ways
of handling it; at least it's reasonably well-centralized in the "new"
way).
- Add support for NOTE_OPEN, NOTE_CLOSE, NOTE_CLOSE_WRITE, and NOTE_READ,
compatible with the same events in FreeBSD.
- Track which kevent notifications clients are interested in receiving
to avoid doing work for events no one cares about (avoiding, e.g.
taking locks and traversing the klist to send a NOTE_WRITE when
someone is merely watching for a file to be deleted, for example).
In support of the above:
- Add support in vnode_if.sh for specifying PRE- and POST-op handlers,
to be invoked before and after vop_pre() and vop_post(), respectively.
Basic idea from FreeBSD, but implemented differently.
- Add support in vnode_if.sh for specifying CONTEXT fields in the
vop_*_args structures. These context fields are used to convey information
between the file system VOP function and the VOP wrapper, but do not
occupy an argument slot in the VOP_*() call itself. These context fields
are initialized and subsequently interpreted by PRE- and POST-op handlers.
- Version VOP_REMOVE(), uses the a context field for the file system to report
back the resulting link count of the target vnode. Return this in tmpfs,
udf, nfs, chfs, ext2fs, lfs, and ufs.
NetBSD 9.99.92.

riastradh | Round of uvm.h cleanup.
The poorly named uvm.h is generally supposed to be for uvm-internal
users only.
- Narrow it to files that actually need it -- mostly files that need
to query whether curlwp is the pagedaemon, which should maybe be
exposed by an external header.
- Use uvm_extern.h where feasible and uvm_*.h for things not exposed
by it. We should split up uvm_extern.h but this will serve for now
to reduce the uvm.h dependencies.
- Use uvm_stat.h and #ifdef UVMHIST uvm.h for files that use
UVMHIST(ubchist), since ubchist is declared in uvm.h but the
reference evaporates if UVMHIST is not defined, so we reduce header
file dependencies.
- Make uvm_device.h and uvm_swap.h independently includable while
here.

pgoyette | 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.

riastradh | branches: 1.48.4;
Change VOP_REMOVE and VOP_RMDIR to preserve lock/ref on dvp.
No change to vp -- the plan is to replace the node by the
componentname in the vop parameters, and let all directory vops do
lookups internally.

| 20-Jun-2016 |
dholland | With the previous we seem to have the changes from -r1.225 of ufs_vnops.c.
(as that was stuff from moving ffs to the new vcache and lfs has also been
moved, this is not surprising)
|
| 1.42 |
| 20-Jun-2016 |
dholland | Merge (effectively) -r1.78 of ufs_extern.h: shift ulfs_makeinode to
lfs_vnops.c and make it file-static there, as that's the only place
it's used.

ufs_vnops.c 1.221 was superseded by later changes

|
| 1.39 |
| 19-Jun-2016 |
dholland | we already have ufs_lookup.c 1.125 and ufs_vnops.c 1.218.
|
| 1.38 |
| 19-Jun-2016 |
dholland | note that we're synced with ufs_vnops.c -r1.217 and ufsmount.h -r1.41
(those changes removed lfs hooks from ufs so shouldn't be merged across)
|
| 1.37 |

dholland | Merge -r1.216 of ufs_vnops.c: comments about maxsymlinklen handling
|
| 1.36 |

pgoyette | Remove historic references to wapbl.
|
| 1.34 |
| 21-Sep-2015 |
dholland | Add 64-bit directory entry structures, and adjust accessors accordingly.
The LFS64 directory entry has a 64-bit inode number. This is stored as
two 32-bit values to avoid inducing 64-bit alignment requirements.
The exposed type for manipulating directory entries is now
LFS_DIRHEADER, following the same convention as e.g. IFILE and SEGUSE.
(But with LFS_ on it, because.)
|
| 1.33 |
| 21-Sep-2015 |
dholland | Oops; LFS_DIRECTSIZ() is going to need the fs as an argument.
Also, it turns out that dirhash needs a compile-time-constant version
of LFS_DIRECTSIZ(LFS_MAXNAMLEN+1), independent of 64-vs-32, so create
LFS_MAXDIRENTRYSIZE for this. Sigh.
|
| 1.32 |
| 15-Sep-2015 |
dholland | Pass around struct lfs_dirheader instead of struct lfs_direct.
|
| 1.31 |
| 15-Sep-2015 |
dholland | Add an accessor function for directory names.
|
| 1.30 |
| 15-Sep-2015 |
dholland | Kill off ulfs_makedirentry; just pass the data to ulfs_direnter instead.
For now, move one copy of the code that allocates and fills in a
temporary struct lfs_direct to the top of ulfs_direnter; but it should
go away shortly.
|
| 1.29 |
| 15-Sep-2015 |
dholland | Add and use accessor functions for more of the directory entry fields.
|
| 1.28 |
| 01-Sep-2015 |
dholland | Add new accessors for the d_type and d_namlen fields of struct lfs_direct.
Napalm the old byteswap access logic for these.
|
| 1.27 |
| 01-Sep-2015 |
dholland | Use the lfs dinode accessors in place of the ufs-derived ones.
(Mostly.)
The ufs-derived ones are fake structure member macros, which are gross
and not very safe. Also, it seems that a lot of places in the lfs code
were using the ffsv1 branch of them unconditionally, and this way it's
guaranteed all those places have been updated.
Found while doing this: for non-devices, have getattr produce NODEV
in the rdev field instead of leaking the address of the first direct
block.

| 31-May-2015 |
hannken | Change lfs from hash table to vcache.
- Change lfs_valloc() to return an inode number and version instead of
a vnode and move lfs_ialloc() and lfs_vcreate() to new lfs_init_vnode().
- Add lfs_valloc_fixed() to allocate a known inode, used by kernel
roll forward.
- Remove lfs_*ref(), these functions cannot coexist with vcache and
their commented behaviour is far away from their implementation.
- Add the cleaner lwp and blockinfo to struct ulfsmount so lfs_loadvnode()
may use hints from the cleaner.
- Remove vnode locks from ulfs_lookup() like we did with ufs_lookup().

riastradh | Tighten some kasserts in ufs_bufio code paths.
|
| 1.22 |
| 27-Mar-2015 |
riastradh | Disentangle buffer-cached I/O from page-cached I/O in UFS.
Page-cached I/O is used for regular files, and is initiated by VFS
users such as userland and NFS.
Buffer-cached I/O is used for directories and symlinks, and is issued
only internally by UFS.
New UFS routine ufs_bufio replaces vn_rdwr for internal use.
ufs_bufio is implemented by new UFS operations uo_bufrd/uo_bufwr,
which sit in ufs_readwrite.c alongside the VOP_READ/VOP_WRITE
implementations.
I preserved the code as much as possible and will leave further
simplification for future commits. I kept the ulfs_readwrite.c
copypasta close to ufs_readwrite.c in case we ever want to merge them
back; likewise ext2fs_readwrite.c.
No externally visible semantic change. All atf fs tests still pass.

dholland | Split lfs from ufs, part 1: cut and paste 15000 lines of ufs as "ulfs".
These are verbatim copies except that I've preserved the ufs rcsids
for reference. Also,
ufs/quota.h -> ulfs_quotacommon.h
ufs/ufs_quota.h -> ulfs_quota.h
Splitting lfs from ufs was ok'd by core some years ago. This is not
from my original tree, which became unmergeable after the several sets
of quota changes; I've done the work over again over the last couple
days.

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.

Update inode member i_flag --> i_state to keep up with kernel changes
Move definition of IN_ALLMOD near the flag it's a mask for.
Now we can see that it doesn't match all the flags, but changing that will
require more careful thought.
Correct confusion between i_flag and i_flags
These will have to be renamed.
Spotted by Riastradh, thanks!
Add an XXX about the missing flags so it's not buried in a commit
message.
now the XXX count for LFS is 260
Rename i_flag to i_state.
The similarity to i_flags has previously caused errors.
Use continue to denote the no-op loop to match netbsd style
newline for extra clarity.
It isn't safe to drain dirops with seglock held, it'll deadlock if there
are any dirops. drain before grabbing seglock.
lfs_dirops == 0 is always true (as we already drained dirops), so omit
that part of the comparison.
Fixes a lot of LFS deadlocks. PR kern/52301
Many thanks to dholland for help analyzing coredumps
Ifdef out KDASSERT which fires on my machine.
Deduplicate sanity check that seglock is held on segunlock
Revert r1.272 fix to PR kern/52301, the performance hit is making things
unusable.
change lfs_nextsegsleep and lfs_allclean_wakeup to use condvar
XXX had to use lfs_lock in lfs_segwait, removed kernel_lock, is this
appropriate?
fix buffer overflow/KASSERT when cookies are supplied
lfs no longer uses the ffs-style struct direct, use the correct minimum
size
from dholland
XXX more wrong
Consistently use {,UN}MARK_VNODE macros rather than function calls.
Not much point doing anything after a panic call
Ask some question about the code in a XXX comment
XXX question our double-flushing of dirops
Fix typo in comment
