inpcb: retire INP_DROPPED and in_pcbdrop()2026-04-12T18:33:07ZGleb Smirnoffglebius@FreeBSD.org2026-04-12T18:33:07Zurn:sha1:40dbb06fa73cac37d57563c07e55efd0cabbd488
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.

chore: replace {0, 0} with {DEV,KOBJ}METHOD_END2026-02-25T05:59:34ZEnji Cooperngie@FreeBSD.org2026-02-21T06:14:46Zurn:sha1:0fc6c3f731a2cca3120798806c330a3081c9424b
Both of the aforementioned macros have been present in FreeBSD
for well over a decade: 2009 for `KOBJMETHOD_END`; 2011 for
`DEVMETHOD_END`.
Adapt all hardcoded references of `{0, 0}` with `DEVMETHOD_END`
and `KOBJMETHOD_END` as appropriate. This helps ensure that
future adaptations to drivers following patterns documented
in driver(9) can be made more easily/without issue.

Rename the function to send_txdataplen_max_flowc_wr to match the
parameter it sets. This function will be reused by other ULP modules.

mbuf: Don't force all M_EXTPG mbufs to be read-only2024-10-31T20:32:31ZJohn Baldwinjhb@FreeBSD.org2024-10-31T20:32:31Zurn:sha1:314cb279959b08811543612a715e47266f685c7b
Some M_EXTPG mbufs are read-only (e.g. those backing sendfile
requests), but others are not. Add a flags argument to
mb_alloc_ext_pgs that can be used to set M_RDONLY when needed rather
than setting it unconditionally. Update mb_unmapped_to_ext to
preserve M_RDONLY from the unmapped mbuf.

cxgbe(4): Changes to ULD list management.2024-07-19T16:12:49ZNavdeep Parharnp@FreeBSD.org2024-07-06T20:43:17Zurn:sha1:cf5e6370f15cffabbbf508083ba7d48ec8abfa79
* Convert t4_uld_list to an array. There will be at most 3 items in the
list and it's simpler to track them in an array with a fixed slot for
each ULD.
* There is no need to refcount ULDs so stop doing that.
* Add uld_ prefix to all members of uld_info.
* Rename async_event to uld_stop to match its actual purpose. Call it
for all ULDs and not just ULD_IWARP.
