02d0c43c | dougm | Aug. 19, 2022, 11:11 p.m. | rb_tree: speed-up double rotation
RB_ROTATE_LEFT (and it symmetric twin) modify the rb-tree, adjusting pointers so that what started as a proper tree ends up a proper tree. When two consecutive rotations move the same node up the tree, some of the pointers changed in the first rotation are immediately changed again in the second - namely, the pointer from the rising node to its new parent, and the pointer from that parent back to the rising node. This change removes from RB_ROTATE macros the responsibility for managing those two pointers, and leaves it to the code that calls for rotations to fix up those pointers afterward. That drops a comparison and a pair of assignments from every INSERT_COLOR or REMOVE_COLOR call that ends in a double rotation. A side-effect of this change is that the SWAP_CHILD macro must take as a parameter a pointer to the node that is changing children, where it is now computed from the old child. Since this macro is called in a couple of places besides the RB_ROTATE macros, those calls are also affected.

During attach we release the lock to call e6000sw_attach_miibus(), which calls mii_attach(). The mii_attach() function calls miibus_readreg() / miibus_writereg(). However, these are set to be e6000sw_readphy_locked(). That is, the read/write phy functions do not acquire the lock, but expect to be called while locked. Simply do not unlock and relock while calling mii_attach().

bffe60ea | emaste | Aug. 19, 2022, 2:38 p.m. | ssh: retire client VersionAddendum
FreeBSD introduced VersionAddendum for the server as a local change in 2001 in commit 933ca70f8f88 and later extended it to the client in commit 9e2cbe04ff4f. In 2012 upstream added support for server VersionAddendum, in commit 23528816dc10. They do not support it for the client. The argument for supporting this in the client is not nearly as strong as for the server, so retire this option to reduce the scope of our local patch set. This also avoids some cases of conflicts in ssh_config during update, as a user's configuration would typically follow the commented-out default VersionAddendum value.

Linux is using 7 bit addressing while FreeBSD uses 8 bit addresses internally, but i2c(8) uses 7 bit address. This confused me when originally doing the code and I thought that 0x50 was the 8bit EDID address while it's the 7bit address and since I did all my testing using this I didn't noticed the problem.
