376	log file reopen should pass opened fd from master process	Tiziano Müller		"When starting nginx all the log files (error_log, access_log) are created and opened by the master process and the filehandles passed to the worker while forking.

On SIGUSR1 the master reopens the files, chown's them and then the worker reopens the files himself. This has several drawbacks:

* It is inconsistent behaviour and rather surprising (sudden change of ownership upon signal). If you really want to do it this way you should chown the files from the very beginning.
* It '''permits the unprivileged nginx user read and write access''' to the current log files which is bad from the security perspective since the unprivileged user also needs to be able to change into/read the log directory

A better solution may be to reopen the log files in the master process as currently done and then use the already available ngx_{read,write}_channel functions to pass the new filehandles down to the worker."	enhancement	accepted	minor		nginx-core					n/a	n/a
