Subject: [PATCH net-next v2 0/2] support SO_PRIORITY cmsg
The changes introduce a new helper function,
`sk_set_prio_allowed`, which centralizes the logic for validating
priority settings. This series adds support for the `SO_PRIORITY`
control message, allowing user-space applications to set socket
priority via control messages (cmsg).
Patch Overview:
Patch 1/2: Introduces `sk_set_prio_allowed` helper function.
Patch 2/2: Implements support for setting `SO_PRIORITY` via control
messages.
v2:
- Suggested by Willem de Bruijn <willemdebruijn.kernel@...il.com>
introduce "sk_set_prio_allowed" helper to check priority setting
capability
- drop new fields and change sockcm_cookie::priority from "char" to
"u32" to match with sk_buff::priority
- cork->tos value check before priority setting
moved from __ip_make_skb() to ip_setup_cork()
- rebased on net-next
