The inpcb flag INP_DROPPED served two purposes. It was used by TCP and subsystems running on top of TCP as a flag that marks a connection that is now in TCPS_CLOSED, but was in some other state before (not a new-born connection). Create a new TCP flag TF_DISCONNECTED for this purpose. The in_pcbdrop() was a TCP's version of in_pcbdisconnect() that also sets INP_DROPPED. Use in_pcbdisconnect() instead. Second purpose of INP_DROPPED was a negative lookup mask in inp_smr_lock(), as SMR-protected lookup may see inpcbs that had been removed from the hash. We already have had INP_INHASHLIST that marks inpcb that is in hash. Convert it into INP_UNCONNECTED with the opposite meaning. This allows to combine it with INP_FREED for the negative lookup mask. The Chelsio/ToE and kTLS changes are done with some style refactoring, like moving inp/tp assignments up and using macros for that. However, no deep thinking was taken to check if those checks are really needed, it could be that some are not. Reviewed by: rrs Differential Revision: https://reviews.freebsd.org/D56186
FreeBSD Source:
This is the top level of the FreeBSD source directory.
FreeBSD is an operating system used to power modern servers, desktops, and embedded platforms. A large community has continually developed it for more than thirty years. Its advanced networking, security, and storage features have made FreeBSD the platform of choice for many of the busiest web sites and most pervasive embedded networking and storage devices.
