2007-10-10r13915: Fixed a very interesting class of realloc() bugs found by Coverity.Jeremy Allison1-9/+2
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)

small modifications, this code may also work on Solaris, as they are derived from the same SVR4 codebase. When the Samba Solaris box is up and running again I will test this. Jeremy. (This used to be commit f8db87b0978be981448eafd57163703e3aeec2cb)

Jeremy. (This used to be commit da6ae57501e3cb971e82eac5bb05efcd9cf443ae)
2000-12-07Working code to read POSIX ACLs on a Linux system using the bestbitsJeremy Allison1-2/+49
ACL patch from http://acl.bestbits.at/. configure support needs more work (just assumes correct headers at the moment). ACL writing needs adding. Jeremy. (This used to be commit 6ae63e502e6adf3666a34aa87860c74e106fdb84)
2000-12-06Cause smbd to use the new posix_acls code, not the old unix_acls code.Jeremy Allison1-0/+12
Currently does exactly the same thing (returns ACLs the same way). This code is written to try and get a POSIX ACL via the abstract sys_XX interface, then fall back to providing a UNIX based ACL if the calls fail. Seems to work. Next step is to add a --with-posix-acls to configure.in and then check on a POSIX ACL system that a complex ACL is returned correctly as an NT ACL. Note that the ACL set (a more complex problem) is not addressed yet. Jeremy. (This used to be commit 4339e20202a876dbadc07980b731f711463b7299)
2000-12-06Make smbd/posix_acls.c use abstract interface.Jeremy Allison1-0/+110
