Summary: sll_family required for bind() on AF_PACKET socket
Product: Documentation
Version: unspecified
Hardware: All
OS: Linux
Status: NEW
Severity: normal
Priority: P1
Component: man-pages
Assignee: documentation_man-pages-ztI5WcYan/[email protected]
Reporter: [email protected]
Regression: No
This is from "man 7 packet":
Quoted 1 line
When you send packets it is enough to specify
sll_family,sll_addr,sll_halen,sll_ifindex. The other fields should be 0.sll_hatypeandsll_pkttypeare set on received packets for your information. For bind onlysll_protocolandsll_ifindexare used.
However, the last sentence is not correct. You have to specifiy sll_family for bind() too, otherwise it will fail.

Resolution|--- |PATCH_ALREADY_AVAILABLE--- Comment #1 from Michael Kerrisk <[email protected]> --- By chance, this was actually reported and fixed a few weeks ago, and the text that will appear in the next man-pages release is:
Fields used for binding are sll_family (should be AF_PACKET), sll_protocol, and sll_ifindex.
