The makefs msdosfs code includes fs/msdosfs/denode.h which directly uses struct buf from <sys/buf.h> rather than the makefs struct m_buf. To work around this problem provide a local denode.h that includes ffs/buf.h and defines buf as an alias for m_buf.

terminating a TCP connection. If a TCP packet must be retransmitted and the data length has changed in the retransmitted packet, due to the internal workings of TCP, typically when ACK packets are lost, then there is a 30% chance that the logic in GetDeltaSeqOut() will find the correct length, which is the last length received. This can be explained as follows: If a "227 Entering Passive Mode" packet must be retransmittet and the length changes from 51 to 50 bytes, for example, then we have three cases for the list scan in GetDeltaSeqOut(), depending on how many prior packets were received modulus N_LINK_TCP_DATA=3: case 1: index 0: original packet 51 index 1: retransmitted packet 50 index 2: not relevant case 2: index 0: not relevant index 1: original packet 51 index 2: retransmitted packet 50 case 3: index 0: retransmitted packet 50 index 1: not relevant index 2: original packet 51 This patch simply changes the searching order for TCP packets, always starting at the last received packet instead of any received packet, in GetDeltaAckIn() and GetDeltaSeqOut().

Multi page rings are mapped using a single hypercall that gets passed an array of grants to map. One of the grants in the array failing to map would lead to the failure of the whole ring setup operation, but there was no cleanup of the rest of the grant maps in the array that could have likely been created as a result of the hypercall. Add proper cleanup on the failure path during ring setup to unmap any grants that could have been created. This is part of XSA-361. Sponsored by: Citrix Systems R&Dcgit

|1158508a||jamie||Feb. 21, 2021, 9:24 p.m.||jail: Add pr_state to struct prison
Rather that using references (pr_ref and pr_uref) to deduce the state of a prison, keep track of its state explicitly. A prison is either "invalid" (pr_ref == 0), "alive" (pr_uref > 0) or "dying" (pr_uref == 0). State transitions are generally tied to the reference counts, but with some flexibility: a new prison is "invalid" even though it now starts with a reference, and jail_remove(2) sets the state to "dying" before the user reference count drops to zero (which was prviously accomplished via the PR_REMOVE flag). pr_state is protected by both the prison mutex and allprison_lock, so it has the same availablity guarantees as the reference counts do.
