2007-10-10r13915: Fixed a very interesting class of realloc() bugs found by Coverity.Jeremy Allison1-11/+6
realloc can return NULL in one of two cases - (1) the realloc failed, (2) realloc succeeded but the new size requested was zero, in which case this is identical to a free() call. The error paths dealing with these two cases should be different, but mostly weren't. Secondly the standard idiom for dealing with realloc when you know the new size is non-zero is the following : tmp = realloc(p, size); if (!tmp) { SAFE_FREE(p); return error; } else { p = tmp; } However, there were *many* *many* places in Samba where we were using the old (broken) idiom of : p = realloc(p, size) if (!p) { return error; } which will leak the memory pointed to by p on realloc fail. This commit (hopefully) fixes all these cases by moving to a standard idiom of : p = SMB_REALLOC(p, size) if (!p) { return error; } Where if the realloc returns null due to the realloc failing or size == 0 we *guarentee* that the storage pointed to by p has been freed. This allows me to remove a lot of code that was dealing with the standard (more verbose) method that required a tmp pointer. This is almost always what you want. When a realloc fails you never usually want the old memory, you want to free it and get into your error processing asap. For the 11 remaining cases where we really do need to keep the old pointer I have invented the new macro SMB_REALLOC_KEEP_OLD_ON_ERROR, which can be used as follows : tmp = SMB_REALLOC_KEEP_OLD_ON_ERROR(p, size); if (!tmp) { SAFE_FREE(p); return error; } else { p = tmp; } SMB_REALLOC_KEEP_OLD_ON_ERROR guarentees never to free the pointer p, even on size == 0 or realloc fail. All this is done by a hidden extra argument to Realloc(), BOOL free_old_on_error which is set appropriately by the SMB_REALLOC and SMB_REALLOC_KEEP_OLD_ON_ERROR macros (and their array counterparts). It remains to be seen what this will do to our Coverity bug count :-). Jeremy. (This used to be commit 1d710d06a214f3f1740e80e0bffd6aab44aac2b0)

2007-10-10r11511: A classic "friday night check-in" :-). This moves muchJeremy Allison1-7/+7
of the Samba4 timezone handling code back into Samba3. Gets rid of "kludge-gmt" and removes the effectiveness of the parameter "time offset" (I can add this back in very easily if needed) - it's no longer being looked at. I'm hoping this will fix the problems people have been having with DST transitions. I'll start comprehensive testing tomorrow, but for now all modifications are done. Splits time get/set functions into srv_XXX and cli_XXX as they need to look at different timezone offsets. Get rid of much of the "efficiency" cruft that was added to Samba back in the day when the C library timezone handling functions were slow. Jeremy.

2007-10-10r7151: Fix for bug #2698. If a unicode to unix charset conversion fails (due ↵Jeremy Allison1-10/+40
to buggy iconv?) we can be left with a filename that doesn't exist on the remote machine. If we then do a findnext with this file the server gets confused and restarts from the beginning of the directory, causing directory listing loops. Fix this by keeping a copy of the "raw" filename data and length and using this as the argument to findnext. This won't fix the incorrect iconv conversion into the finfo struct but at least it ensures that directory listings always terminate. Tested against NTFS and FAT directories. Jeremy.

2007-10-10r5520: fix last remaining dfs issues with smbclient.Gerald Carter1-2/+8
* all the unix extension commands should work * send the correct TRANS2_FINDFIRST format to 2k to get a listing from a msdfs root share (tested against smbd as well). * mkdir, rmdir, etc... all seem ok. I'm sure bugs will pop up so keep testing. Last thing I plan on doing is to clean up the horrible mess with connection management in smbclient and global variables (so i can move the cli_cm_xx() routines to a separate file).

2003-08-02Correct fix (removed the earlier band-aid) for what I thought was a signingJeremy Allison1-2/+10
bug with w2k. Turns out that when we're doing a trans/trans2/nttrans call the MID and send_sequence_number and reply_sequence_number must remain constant. This was something we got very wrong in earlier versions of Samba. I can now get a directory listing from WINNT\SYSTEM32 with the older earlier parameters for clilist.c This still needs to be fixed for the server side of Samba, client appears to be working happily now (I'm doing a signed smbtar download of an entire W2K3 image to test this :-).

This patch catches up on the rest of the work - as much string checking as is possible is done at compile time, and the rest at runtime.

2001-08-10A rewrite of the error handling in the libsmb client code. I've separatedTim Potter1-2/+3
out the error handling into a bunch of separate functions rather than all being handled in one big function. Fetch error codes from the last received packet: void cli_dos_error(struct cli_state *cli, uint8 *eclass, uint32 *num); uint32 cli_nt_error(struct cli_state *); Convert errors to UNIX errno values: int cli_errno_from_dos(uint8 eclass, uint32 num); int cli_errno_from_nt(uint32 status); int cli_errno(struct cli_state *cli); Detect different kinds of errors: BOOL cli_is_dos_error(struct cli_state *cli); BOOL cli_is_nt_error(struct cli_state *cli); BOOL cli_is_error(struct cli_state *cli); This also means we now support CAP_STATUS32 as we can decode and understand NT errors instead of just DOS errors. Yay! Ported a whole bunch of files in libsmb to use this new API instead of the just the DOS error. (This used to be commit 6dbdb0d813f3c7ab20b38baa1223b0b479aadec9)
