* Use password/group cache functions and avoid stashing a pointer tomillert2018-09-211-32/+20
| | | | | | | | the return value of getgrgid(3) or getgrnam(3) which relies on undefined behavior. The rdist server will now use getgroups(2) to determine group membership of the invoking user. In addition, there is now one implementation of tilde expansion instead of two. OK tb@ tim@
* Fix a crash in rdistd triggered by the recent getpw{ent,nam,uid}millert2018-09-091-4/+6
| | | | | | | | | | | changes. This stems from rdist stashing a pointer to the static area used by getpw{ent,nam,uid} and using it to avoid repeating passwd lookups when pw->pw_name matches the user to be looked up. This relied on undefined behavior, and with the recent passwd changes, is no longer possible as the old pointer will be invalidated. A better approach is to use the upcoming uid_from_user(3) functions. Found by and fix OK tim@

* Avoid compiler warning about zero-length printf format strings.millert2016-03-301-3/+3
| | | | | | Allow a NULL format in message() and switch the two calls to error() and message() with an empty format string to using NULL. OK deraadt@
* The change to make mkstemp(3) require at least 6 trailing Xs brokemillert2016-03-301-14/+8
| | | | | | | | | | rdistd for directories that do not exist on the destination. Calling mkstemp(3) twice with the same format (filled in by the first mkstemp(3) call) is bogus so call chkparent() *before* mkstemp(3) instead of only on error. This costs an extra lstat(2) in the case where the directory already exists but simplifies the code and doesn't rely on undefined behavior (namely, the state of the template when mkstemp fails). OK tim@

| | | | | | | | | rdist/client.h and rdistd/server.h Only put #includes in .h files that are necessary for the .h to be used; all other #includes go in the .c files Move all extern variable declarations to the .h files, renaming local variables to avoid shadowing Replace me_type member of mntent_t with an "is NFS?" flag bit

Switch to PATH_MAX, NGROUPS_MAX, HOST_NAME_MAX+1, LOGIN_NAME_MAX, etc. Change MIN() and MAX() to local definitions of MINIMUM() and MAXIMUM() where sensible to avoid pulling in the pollution. These are the files confirmed through binary verification. ok guenther, millert, doug (helped with the verification protocol)
