2010-01-08Re-fix bug 5202 - cannot change ACLs on writable file with "dos filemode=yes"Jeremy Allison1-0/+3
This bug re-occurred for 3.3.x and above. The reason is that to change a NT ACL we now have to open the file requesting WRITE_DAC and WRITE_OWNER access. The mapping from POSIX "w" to NT permissions in posix_acls doesn't add these bits when "dos filemode = yes", so even though the permission or owner change would be allowed by the POSIX ACL code, the NTCreateX call fails with ACCESS_DENIED now we always check NT permissions first. Added in the mapping from "w" to WRITE_DAC and WRITE_OWNER access. Jeremy.

2010-01-07s3:passdb: store the plain nt passwords hashes in history, not salted md5Michael Adam1-5/+10
This is in order to be able to do challenge response with the history, so that this can be checked when an invalid password was entered: If the given password is wrong but in the history, then the bad password count should not be updated... The "lucky" bit here is that the md5 has and the nt hash (md4) both are 16 bytes long. This is part of the fix for bug #4347 . Michael
2010-01-07s3:smbd:password_in_history: treat entry with 0 salt as 0 + plain nt hashMichael Adam1-6/+24
This is to introduce a new format of the password history, maintaining backwards compatibility: The old format was 16 byte hash + 16 byte md5(salt + nt hash). The new format is 16 zero bytes and 16 bytes nt hash. This will allow us to respect the last X entries of the nt password history when deciding whether to increment the bad password count. This is part of the fix for bug #4347 . Michael
2010-01-07s3: Remove some code that has become unnecessaryVolker Lendecke1-8/+0
The code I just removed was checked in with e5466fffc286a99f as a bug fix for https://bugzilla.samba.org/show_bug.cgi?id=3319. With the changes to is_visible_file made with 9e8b8f8c16612 these lines have become unnecessary, even with "hide unreadable = yes" dead msdfs symlinks show. This is because we can not stat(2) them and default to showing them. Why this change? I have a user who wants to use "hide unreadable" on msdfs links. Because you can't edit acls on symlinks themselves, the user created the targets as bogus, empty files that just exist as acl placeholders. With the code in place that this patch removes, we never allow this to work. Jeremy, please check! :-) Thanks, Volker

2010-01-07s3:auth:check_sam_security: null out sampass after it has been stolen.Michael Adam1-0/+1
So that a later talloc_free would not harm. I could have used talloc_move instead of talloc steal in make_server_info_sam(), but this would have required a change of the signature. Michael
2010-01-07s3:auth:sam_password_ok: take username, acct_ctrl and nt/lm hashes, not sampassMichael Adam1-14/+20
This is in preparation to extending check_sam_security to also check against the password history before updating the bad password count. This way, sam_password_ok can more easily be reused for that purpose. Michael
2010-01-07s3:auth: use data_blob_null instead of data_blob(NULL, 0) in sam_password_ok()Michael Adam1-2/+2
This way it is more explicit that there is no allocated data here that may leak. Michael
2010-01-07s3:auth:sam_password_ok: fix allocation of a data blob.Michael Adam1-1/+1
data_blob(mem_ctx, 16) does not use mem_ctx as a talloc ctx but copies 16 bytes from mem_ctx into the newly allocated data blob. This can not have been intentional. A blank uint8_t array of length 16 is allocated by passing NULL instead of mem_ctx. And using data_blob_talloc(mem_ctx, NULL, 16) adds the allocated blank 16 byte array to mem_ctx - so this is what must have been intended. Michael

This is not strictly necessary, since this only leaks into the struct samu, and this is not so long-lived in the code path that changes the password, but it definitely correct and does not harm. Michael
