Subject: [MPTCP] [PATCH 12/24] bpfilter: switch bpfilter_ip_set_sockopt to sockptr_t
Date: Mon, 20 Jul 2020 14:47:25 +0200	[thread overview]
Message-ID: <20200720124737.118617-13-hch@lst.de> (raw)
In-Reply-To: 20200720124737.118617-1-hch@lst.de

[-- Attachment #1: Type: text/plain, Size: 4705 bytes --]

This is mostly to prepare for cleaning up the callers, as bpfilter by
design can't handle kernel pointers.

Subject: [Bridge] [PATCH 12/24] bpfilter: switch bpfilter_ip_set_sockopt to sockptr_t
Date: Mon, 20 Jul 2020 14:47:25 +0200	[thread overview]
Message-ID: <20200720124737.118617-13-hch@lst.de> (raw)
In-Reply-To: <20200720124737.118617-1-hch@lst.de>

This is mostly to prepare for cleaning up the callers, as bpfilter by
design can't handle kernel pointers.
