[-- Attachment #1 --] Hi list, I was asked if it is possible to MFC r281599 in FreeBSD 10: --- Fix an old and well-documented use-after-free race condition in TCP timers: - Add a reference from tcpcb to its inpcb - Defer tcpcb deletion until TCP timers have finished --- https://svnweb.freebsd.org/base?view=revision&revision=281599 First, I thought it was no possible as it touches struct tcp_timer/struct tcpcb_mem. Second, John pointed me that these two structures are used only internally. The only side effect I was able to find is the increase of struct tcpcb_mem size: - stable/10: struct tcpcb_mem size is 1024 bytes - stable/10 + tcp timer change: struct tcpcb_mem size is 1032 bytes - currently in head: struct tcpcb_mem size is 1048 bytes If you have extra concerns on MFC-ing this change please scream. Without nice yelps I plan to "MFC after: 1 month" (around May 16th). Thanks. -- Julien [-- Attachment #2 --] -----BEGIN PGP SIGNATURE----- Comment: GPGTools - https://gpgtools.org iQEcBAEBCgAGBQJVSLsnAAoJEKVlQ5Je6dhx5ecIAJY06figfPivHZJ5Waugmqs4 IzBfWprlSceunaVnIKBChd76TpYtvqsKkweUQZn9EUhxIqHovIgVnIB2c8W/XPWs 78JiPBFH5jGYkSAR7/ekyFkDmEOR5gAcGqwtH2DgcIzUbTmIHBNjADrSnhmAow26 HjglhFBJUuRmubGTNKpDJld36D1+Yb8/GpqJcgsfgyPObhnlIcl/x4x7i6Yw0xp4 IVtqBPBDwV7172ZBpxjlyNtfw5y2gGx3+nRWZXjz4SL4oQxQuIYg8Tx4QL+rvtV6 SgoEiCrpKzk27iiZUoXVMOE/XQnF5nVxFGZwKJ7wkvJh69GshrDRCFznRV/A4DE= =ZRUX -----END PGP SIGNATURE-----
