Summary |
0001593: specify whether struct sockaddr_un.sun_path can be a flexible array member |
|
Description |
As briefly discussed on austin-group-l, the Standard currently uses flexible array member notation for struct sockaddr_un.sun_path, and this causes some confusion. No implementations are known to use a flexible array member, and furthermore, such an implementation would mean that struct sockaddr_storage would not be suitable for encapsulating a struct sockaddr_un as is intended (unless the size of struct sockaddr_storage were SIZE_MAX, which is absurd and not appropriate for automatic allocation).
If this Desired Action is considered too stringent, an alternative could be to permit sun_path to be a flexible array member. |
|
Desired Action |
Line numbers are from the 1003.1-202x Draft 2, May 2021 document.
At page 403, after line 13894 (the definition of struct sockaddr_un's members), insert the following sentence:
"The sun_path member shall have non-zero size."
At line 13903 in the APPLICATION USAGE, modify the sentence so that it reads "Applications should not assume that sun_path can hold {_POSIX_PATH_MAX} bytes (256)." |
