Subject: [PATCH net-next v3 0/3] SO_PRIORITY cmsg patch summary
Introduce a new helper function, `sk_set_prio_allowed`,
to centralize the logic for validating priority settings.
Add support for the `SO_PRIORITY` control message,
enabling user-space applications to set socket priority
via control messages (cmsg).
Patch Overview:
Patch 1/3: Introduce `sk_set_prio_allowed` helper function.
Patch 2/3: Add support for setting `SO_PRIORITY` via control messages
Patch 3/3: Add test for SO_PRIORITY setting via control messages
v3:
- Updated cover letter text.
- Removed priority field from ipcm_cookie.
- Removed cork->tos value check from ip_setup_cork, so
cork->priority will now take its value from ipc->sockc.priority.
- Replaced ipc->priority with ipc->sockc.priority
in ip_cmsg_send().
- Modified the error handling for the SO_PRIORITY
case in __sock_cmsg_send().
- Added missing initialization for ipc6.sockc.priority.
- Introduced cmsg_so_priority.sh test script.
- Modified cmsg_sender.c to set priority via control message (cmsg).
- Rebased on net-next
v2:
https://lore.kernel.org/netdev/20241102125136.5030-1-annaemesenyiri@gmail.com/
- Introduced sk_set_prio_allowed helper to check capability
for setting priority.
- Removed new fields and changed sockcm_cookie::priority
from char to u32 to align with sk_buff::priority.
- Moved the cork->tos value check for priority setting
from __ip_make_skb() to ip_setup_cork().
- Rebased on net-next.
