2010-02-17Fix bug #7146 - Samba miss-parses authenticated RPC packets.Jeremy Allison1-0/+3
Parts of the Samba RPC client and server code misinterpret authenticated packets. DCE authenticated packets actually look like this : +--------------------------+ |header | | ... frag_len (packet len)| | ... auth_len | +--------------------------+ | | | Data payload | ... .... | | +--------------------------+ | | | auth_pad_len bytes | +--------------------------+ | | | Auth footer | | auth_pad_len value | +--------------------------+ | | | Auth payload | | (auth_len bytes long) | +--------------------------+ That's right. The pad bytes come *before* the footer specifying how many pad bytes there are. In order to read this you must seek to the end of the packet and subtract the auth_len (in the packet header) and the auth footer length (a known value). The client and server code gets this right (mostly) in 3.0.x -> 3.4.x so long as the pad alignment is on an 8 byte boundary (there are some special cases in the code for this). Tridge discovered there are some (DRS replication) cases where on 64-bit machines where the pad alignment is on a 16-byte boundary. This breaks the existing S3 hand-optimized rpc code. This patch removes all the special cases in client and server code, and allows the pad alignment for generated packets to be specified by changing a constant in include/local.h (this doesn't affect received packets, the new code always handles them correctly whatever pad alignment is used). This patch also works correctly with rpcclient using sign+seal from the 3.4.x and 3.3.x builds (testing with 3.0.x and 3.2.x to follow) so even as a server it should still work with older libsmbclient and winbindd code.

2007-10-10r17107: Make the 200 ms timeout value tunable in local.h...Jeremy Allison1-0/+3
Might need to be a parameter ? Jeremy. (This used to be commit 98d8d9399bb287319578daaf2a2fb42f3c48f858)
2007-10-10r14763: Add a new tuning parameter, open files database hash size,Jeremy Allison1-1/+1
this allows us to experiment with ensuring the tdb hash size for our open files and locking db are appropriately sized. Make the hash size larger by default (10007 instead of 1049) and make the locking db hash size the same as the open file db hash size. Jeremy.

about it to stop account lockouts with "security=server" mode. Sorry for the delay David. Jeremy. (This used to be commit e8819715038ed49b07ed5639b1b88ad12e994b53)
2001-05-02Had to add a "pam password change" parameter (defaults to "off") and inlinedJeremy Allison1-4/+0
the pam password change code to ensure that existing and working password chat scripts don't break with 2.2.1. PAM password changing has to be explicitly requested. Allowed wildcards in pam password change matching (matches password chat script matching). Had to add const (sorry Tim :-) to ms_fnmatch() to stop warnings. Don't worry - the const changes are isolated and don't cause any other warnings :-). Jeremy. (This used to be commit 47b4d82536c09bffe3a0d9917fa31d935f1be7d8)

2001-03-13this patch does a number of things:Andrew Tridgell1-3/+0
- removes SMB_ALIGNMENT. That macro caused all sorts of problems with getting unicode aligned right in sub-protocols (such as SMBtrans and SMBtrans2). I believe the performance reasons for having SMB_ALIGNMENT has gone away with the new variants of the SMB protocol anyway, as newer commands tend to have their own internal alignment. - fix the locations where we set smb_flg2 to absolute values. We must never do this if we want a hope of coping with unicode. - add initial support for unicode on the wire in smbd. Currently enabled using SMBD_USE_UNICODE environment variable. (This used to be commit b98b1435e9d8f8622444c9ff33082977e661f16b)

(This used to be commit f137648504362479143d50477fa38ebf7147968b)
2000-01-03added the unexpected packet database (unexpected.tdb)Andrew Tridgell1-0/+1
this means "nmblookup -S" now always works, even with broken servers the database stores all unexpected replies and these can be accessed by any client. while doing this I cleaned up a couple of functions, and put in place a better trn_id generator. in most places the code got quite a bit simpler due to the addition of simple helper functions. I haven't yet put the code in to take advantage of this for pdc replies - that will be next. Jeremys pdc finding code will then work :) (This used to be commit 280e6359d36c9bc8dcded302f15c3a1db8e3feeb)

1998-11-09I talked to Dave Miller and he thinks that we should have TCP_NODELAYAndrew Tridgell1-0/+8
on by default on OSes that support it, given the network IO pattern that Samba uses. He doesn't think it will cause problems. (This used to be commit 15016aa024854ca56ef20d1f29f54f9698a1911b)
1998-10-21at the interop Isaac (at least I _think_ it was Isaac) said that if aAndrew Tridgell1-0/+4
MS client doesn't respond to a oplock break request then we might try resending the request. This morning Sues Win95 machine had this problem (thus forcing me to do something about it!). When starting winword her box refused to answer an oplock break request. I have added code to resend the oplock break request up to 3 times at 10 second intervals before killing the socket. of course, as soon as I did this her box started to behave again so I haven't been able to tell if this fix actually works, but it can't be worse than dropping the socket immediately. (This used to be commit a1c4d8351b9171416693e6d7a9045bdce9217edb)
1998-09-30Upped default MAX_OPEN_FILES to 10000 after conversation with tridge.Jeremy Allison1-1/+1
As we're only using 1 bit per fd when idle it doesn't matter too much.... Jeremy. (This used to be commit dba55b2d3453bd18e1a0cb031d012733e5a214b9)
1998-09-30(Finally) implemented "max open files" as a global smb.conf parameter.Jeremy Allison1-0/+11
Sets up the files array correctly - limited by the smb.conf parameter and by the max fd's per process as found by getrlimit(). Jeremy. (This used to be commit eca24bd24352c688cdf48c1ef14adb8ac353468f)
1998-09-26changed the default filesystem type to NTFS (from Samba)Andrew Tridgell1-1/+1
I've finally changed this because I've found a real effect that this has. Win95 shows long filenames in a directory listing in a dos box only if this is set to NTFS or HPFS (only ones I've found so far anyway). If NTFS poses problems of some kind then we should try HPFS I wonder if this change will trigger any attempts to use ACLs ? (This used to be commit 410d54fa0dba319e802d7327d89c4c1e61f2db65)

1998-09-18gto ri of a bunch more #ifdef LARGE_SMB_OFF_T checks by introducing aAndrew Tridgell1-0/+5
SOFF_T() macro for setting an SMB_OFF_T variable also limited mmap based reads to MAX_MMAP_SIZE. We really can't mmap 2^50 bytes due to virtual address space problems. (This used to be commit 4e784b18899eddd2399a51fa7d8c219560432922)
1998-08-17moved connection_struct handling code into smbd/conn.c and changed itAndrew Tridgell1-6/+0
to a linked list with bitmap format. (This used to be commit b7aaab1b6b2d2f72b2bb7c11f5c7bf081a6093d9)
1998-08-17some cleanups from the conversion of Pipes[] to a linked list. I alsoAndrew Tridgell1-3/+0
removed most cases where a pnum is used and substituted a pipes_struct*. in files.c I added a offset of 0x1000 to all file handles on the wire. This makes it much less likely that bad parsing will give us the wrong field. (This used to be commit 8bc2627ff28d340db65bfa017daca2dc291d5ef7)
