Subject: [PATCH v2 0/3] A trio of vchiq bulk transfer fixes
Date: Tue, 5 Jan 2021 16:20:27 +0000 [thread overview]
Message-ID: <20210105162030.1415213-1-phil@raspberrypi.com> (raw)
The recent batch of vchiq improvements broke bulk transfers in two ways:
1. The userdata associated with a transfer was lost in the case that a
non-blocking mode was used.
2. The 64-bit ioctl compatibility shim for a bulk transfer used the
wrong ioctl command.
This patch set fixes both of those bugs, and adds a security-related
note to the TODO file.
Changes in v2:
- Expand the commit message on patch 1 to clarify the impact of the
bug, and add Tested-by.
- Add commit 3 with an additional TODO item.
- Change the name of the patch set to be numerically accurate.
