|
| 1.20 |
| 09-Mar-2011 |
drochner | -start to make the GZIP code similar to DEFLATE: make error handling
work the same way, grow output buffer exponentially and kill
reallocation of metadata
-minor cleanup, make definitions private which are implementation
details of deflate.gzip
|
| 1.19 |
| 24-Feb-2011 |
drochner | small modifications in dealing with the unknown result size of compression/
decompression:
-seperate the IPCOMP specific rule that compression must not grow the
data from general compression semantics: Introduce a special name
CRYPTO_DEFLATE_COMP_NOGROW/comp_algo_deflate_nogrow to describe
the IPCOMP semantics and use it there. (being here, fix the check
so that equal size is considered failure as well as required by
RFC2393)
Customers of CRYPTO_DEFLATE_COMP/comp_algo_deflate now always get
deflated data back, even if they are not smaller than the original.
-allow to pass a "size hint" to the DEFLATE decompression function
which is used for the initial buffer allocation. Due to the changes
done there, additional allocations and extra copies are avoided if the
initial allocation is sufficient. Set the size hint to MCLBYTES (=2k)
in IPCOMP which should be good for many use cases.
|
| 1.18 |
| 18-Feb-2011 |
drochner | redo result buffer allocation, to avoid dynamic allocations:
-use exponentially growing buffer sizes instead of just linear extension
-drop the dynamic allocation of buffer metadata introduced in rev.1.8 --
if the initial array is not sufficient something is wrong
-apply some (arbitrary, heuristic) limit so that compressed data
which extract into insane amounts of constant data don't kill the system
This addresses PR kern/36864 by Wolfgang Stukenbrock. Some tuning
might be useful, but hopefully this is an improvement already.
|
| 1.17 |
| 18-Feb-2011 |
drochner | address the obvious byteorder and alignment problems in gzip size/crc
tail, should fix PR kern/44210 by Wolfgang Stukenbrock
being here, fix a bug in crc calculation of decompressed data, and
actually verify the crc
|
| 1.16 |
| 17-Feb-2011 |
drochner | The decompressor in sys/net/zlib.c has a bug: It returns Z_BUF_ERROR after
a successful decompression in rare cases. A necessary but not sufficient
condition seems to be that the decompressed data end exactly at the end
of an allocated output buffer. (I can reproduce this reliably with
a userland program built against kernel zlib. Userland libz is much
newer and not affected.)
Since kernel zlib is based on an old version and heavily modified, I don't
dare to touch it. So catch this case in the wrapper.
Being here, reorder deflate/inflate error handling and add comments
to make understandable what is tested and why.
|
| 1.15 |
| 16-Feb-2011 |
drochner | -avoid allocation of an extra result buffer and data copy in case
the DEFLATE complssion/decompression result is within a single
buffer already
-simplify bookkeeping of allocated buffers (and don't waste the
last member of the metadata array)
from Wolfgang Stukenbrock per PR kern/36865 (with some cleanup
of error handling by me)
The Gzip compression case can be improved too, but for now I've applied
the buffer bookkeeping changes.
tested with IP4 IPCOMP
|
| 1.14 |
| 10-Feb-2011 |
drochner | whan compressing, set the Z_FINISH flag to zlib to tell that
the data chunk is the final one, which makes that zlib issues the
proper termination marker
(KAME IPSEC does this, but doesn't check eagerly in the receive
path, so the missing termination didn't cause problems so far)
closes my PR kern/44539
being here, replace the Z_PARTIAL_FLUSH flag which is marked
deprecated by zlib by Z_SYNC_FLUSH in the decompression path
(tested with IPv4 IPCOMP on i386)

darran | branches: 1.13.4; 1.13.6; 1.13.8;
Fixes PR kern/41069 and PR kern/41070.
Extends the Opencrypto API to allow the destination buffer size to be
specified when its not the same size as the input buffer (i.e. for
operations like compress and decompress).
The crypto_op and crypt_n_op structures gain a u_int dst_len field.
The session_op structure gains a comp_alg field to specify a compression
algorithm.
Moved four ioctls to new ids; CIOCGSESSION, CIOCNGSESSION, CIOCCRYPT,
and CIOCNCRYPTM.
Added four backward compatible ioctls; OCIOCGSESSION, OCIOCNGSESSION,
OCIOCCRYPT, and OCIOCNCRYPTM.
Backward compatibility is maintained in ocryptodev.h and ocryptodev.c which
implement the original ioctls and set dst_len and comp_alg to 0.
Adds user-space access to compression features.
Adds software gzip support (CRYPTO_GZIP_COMP).
Adds the fast version of crc32 from zlib to libkern. This should be generally
useful and provide a place to start normalizing the various crc32 routines
in the kernel. The crc32 routine is used in this patch to support GZIP.
With input and support from tls@NetBSD.org.

dsl | Change about 4500 of the K&R function definitions to ANSI ones.
There are still about 1600 left, but they have ',' or /* ... */
in the actual variable definitions - which my awk script doesn't handle.
There are also many that need () -> (void).
(The script does handle misordered arguments.)

Add ipv6 support for fast_ipsec
Note that currently, packet with extensions headers are not correctly
supported
Change the ipcomp logic
Add sysctl tree to modify the fast_ipsec options related to ipv6. Similar
to the sysctl kame interface.
Choose the good default policy, depending of the adress family of the
desired policy
Increase the refcount for the default ipv6 policy so nobody can reclaim it
Always compute the sp index even if we don't have any sp in spd. It will
let us to choose the right default policy (based on the adress family
requested).
While here, fix an error message
Use dynamic array instead of an static array to decompress. It lets us to
decompress any data, whatever is the radio decompressed data / compressed
data.
It fixes the last issues with fast_ipsec and ipcomp.
