2024-04-12Fix race between rip_input() and soisdisconnected().Alexander Bluhm
Setting SS_CANTRCVMORE is protected by mutex of receive socket buffer. The raw inpcb loop in rip_input() does a lockless access. Protect it with READ_ONCE(), although it is not perfect. Check the socket buffer state again when the mutex is held. Drop and count the packet that is processed between the checks. Currently soisdisconnected() is called with exclusive net lock. The new code also works without net lock. OK mvs@

2024-04-11Prevent changing interface loopback flag from userland.Alexander Bluhm
IFF_LOOPBACK is telling userland the behaviour of a specific driver, it is supposed to be static and permanent. Clearing the loopback flag on lo0 could lead to a kernel crash due to inconsistent multicast igmp group. Reported-by: syzbot+2f24ed6c8ddb2d6bb22c@syzkaller.appspotmail.com OK claudio@ deraadt@
2024-04-11Don't take solock() in soreceive() for SOCK_RAW inet sockets.Vitaliy Makkoveev
For inet sockets solock() is the netlock wrapper, so soreceive() could be performed simultaneous with exclusively locked code paths. These sockets are not connection oriented, they don't call pru_rcvd(), they can't be spliced, they don't set `so_error'. Nothing to protect with solock() in soreceive() path. `so_rcv' buffer protected by `sb_mtx' mutex(9), but since it released, sblock() required to serialize concurrent soreceive() and sorflush() threads. Current sblock() is some kind of rwlock(9) implementation, so introduce `sb_lock' rwlock(9) and use it directly for that purpose. The sorflush() and callers were refactored to avoid solock() for raw inet sockets. This was done to avoid packet processing stop. Tested and ok bluhm.
2024-04-11Take solock_shared() in soo_stat().Vitaliy Makkoveev
Only unix(4) and tcp(4) sockets set (*pru_sence)() handler. The rest of soo_stat() is the read only access. ok bluhm

2024-04-11Add support for media types from the extended ethernet capabilities fields.Jonathan Matthew
If none of the regular ethernet capabilities are present, check the extended capabilities. Since we only report that the link is active if there's a detected media type, this isn't just a cosmetic change. Joerg Streckfuss reported that a gigabit SFP didn't work in a ConnectX-6 Lx, and tested that this change makes it work. ok dlg@

2024-04-10Remove `head' socket re-locking in sonewconn().Vitaliy Makkoveev
uipc_attach() releases solock() because it should be taken after `unp_gc_lock' rwlock(9) which protects the `unp_link' list. For this reason, the listening `head' socket should be unlocked too while sonewconn() calls uipc_attach(). This could be reworked because now `so_rcv' sockbuf relies on `sb_mtx' mutex(9). The last one `unp_link' foreach loop within unp_gc() discards sockets previously marked as UNP_GCDEAD. These sockets are not accessed from the userland. The only exception is the sosend() threads of connected sending peers, but they only sbappend*() mbuf(9) to `so_rcv'. So it's enough to unlink mbuf(9) chain with `sb_mtx' held and discard lockless. Please note, the existing SS_NEWCONN_WAIT logic was never used because the listening unix(4) socket protected from concurrent unp_detach() by vnode(9) lock, however `head' re-locked all times. ok bluhm

2024-04-10Unlock dosigsuspend() and with that some aspects of ppoll and pselectClaudio Jeker
Change p_sigmask from atomic back to non-atomic updates. All changes to p_sigmask are only allowed by curproc (the owner). There is no need for atomic instructions here. p_sigmask is mostly accessed by curproc with the exception of ptsignal(). In ptsignal() p_sigmask is now only read once unless a SSLEEP proc gets the signal. In that case recheck the p_sigmask before wakeup to ensure that no unnecessary wakeup happens. Add some KASSERT(p == curproc) to ensure this precondition. sigabort() is special since it is also called by ddb but apart from that only works for curproc. With and OK mvs@ OK mpi@

2024-04-09Plug route leak in IP output.Alexander Bluhm
If no struct route is passed to ip_output() or ip6_output(), it uses its own iproute on the stack. In that case any route entry in the local route cache has to be freed. After pf decides to reroute, struct route is reset to NULL. Then the route reference counter has to be released. Call rtfree() without needless NULL check. OK mvs@
